The pipe bending machine is a new type of pipe bending tool with a curved pipe function and a topping function. It has many advantages such as reasonable structure, safe use, convenient operation, reasonable price, fast loading and unloading, easy to carry, multi-purpose, etc. It has a large share in the domestic hydraulic market, mainly used in factories, warehouses, docks, buildings, railways and automobiles. Wait for the installation of pipes and repairs. In addition to the elbow function, it can also be used to remove the elbow parts as a separate hydraulic overhead machine.

Then, when purchasing back, pay attention to the following points when using:

1. Before operation, please check whether the lubrication points of the machine are lack of oil, whether the safety protection device is reliable, whether the movement mechanism is loose, etc.

2. Start the oil pump and check whether the system pressure is within the specified range. If it is high, it will damage the hydraulic components and waste power. If it is too low, it will affect the work.

3. Adjust the position and required angle of the part and position the part to the required length.

4. Adjust the vertical lifting rail to make the guiding mold pressing cylinder advance to clamp the tight iron pipe.

5. The clamping mold clamping cylinder can clamp the iron pipe.

6. Normal operation Put the workpiece into the bending mold, and the front end is in contact with the positioning, and the foot switch can be stepped on.

7. After the work is finished, cut off the power supply and do the cleaning and lubrication work.

8. In case of emergency, press the emergency stop button, then turn the twist switch to the manual position and use manual reset. If the fault occurs, please report it in time.

Let's talk about eight methods for tube maintenance:

One: When operating, it must be operated in strict accordance with the operating regulations (emphasis).

Two: The tube bending machine must be kept clean, and the unpainted parts should be coated with anti-rust grease.

Three: Before each start-up, according to the lubrication chart, the lubricant should be added regularly, fixed point and quantitatively. The oil should be clean and free of sediment.

Four: Regularly check the repair switch, insurance, handle, to ensure that its work is reliable.

Five: The lubricant in the motor bearing should be replaced regularly, and often check whether the motor part is working properly.

Six: Regularly check whether the V-belt, handle, knob, and button are damaged. If the wear is serious, replace it in time.

Seven: It is strictly forbidden for non-designated personnel to operate the equipment. It is usually necessary to stop the person from leaving the machine.

Eight: 10 minutes before leaving work every day, the pipe bending machine is lubricated and cleaned.

Finally, the experts and experts said that in addition to the function of bending, the cylinder in the elbow part can be removed as a separate hydraulic topping machine. Generally, it has good anti-emulsification performance and good anti-foaming performance. Lubricating oil with good performance.

Everyone knows that the pipe bending machine is the most common type of machine in our life. It mainly bends an object and is mainly used for electric power construction, public railway construction, boilers, bridges, ships, furniture, decoration, etc. Pipe laying and repairing has the advantages of many functions, reasonable structure and simple operation. The pipe bender reduces labor costs in the traditional mode and greatly improves work efficiency. We can't do without bender products around our lives. For example, the office seats we go to work need to use pipe benders where there are pipes bent, especially in the industrial field, bend pipes are widely used. Important parts. So what is the standard for the bending machine equipment? See the following:

I. Complete and complete parts, quality meets requirements

1 The main drive and auxiliary system parts are complete and complete, the hydraulic system has no leakage, complete accessories, and the quality meets the technical requirements.

2 Pressure gauge, oil mark and pressure relay are sensitive and reliable, and the oil quality meets the technical standards of hydraulic oil.

3 The body and the foundation foot are firmly connected without looseness.

2. The equipment is operating normally and has good performance.

1 Under the rated load condition, the relay protection system is sensitive and reliable, and reaches the nameplate output standard.

2 The equipment is well lubricated, the oil passage is smooth, the oil quality meets the technical requirements, the lubrication is fixed, and the oil is filtered in three stages.

3 All the gears in the gearbox of the machine tool are sealed with splash and the other parts are dispersed and single-point lubricated.

Three technical information is complete and accurate

2 When the equipment is running, the statistics are accurate, the operation record is complete, there are reasonable operating procedures, and the equipment maintenance and repair procedures are carefully implemented.

3 Technical specifications, consumable parts drawings are complete, and there are assembly drawings that meet the maintenance needs.

4. Equipment and environment are neat and clean

1 The environment is clean and tidy, no dripping or leaking. When the work stops, the tools and the tires return to their original positions.

2 There are prescribed safety passages, and the accessories are arranged neatly and reasonably.

So what is the standard for the bend radius of the bend?

First of all, one tube and one mold, for a tube, no matter how many bends, regardless of the bending angle (not greater than 180 ° C), the bending radius is preferably uniform. Since one tube is a mold, what is the appropriate bending radius for pipes of different diameters? The minimum bending radius depends on the material properties, the bending angle, the allowable amount of thinning outside the curved wall and the size of the inner wrinkles, and the ellipticity at the bend. In general, the minimum bend radius should not be less than 2 to 2.5 times the outer diameter of the tube. For the duct of an aircraft or an engine, since the various pipes are traversed in a limited space inside and outside, the bending radius of the pipe is preferably small. The small bending radius makes the shape of the tube change flexible and adaptable. For large diameter engines and large aircraft, a slightly larger bend radius can be chosen with a looser piping arrangement. Because the large bending radius facilitates bending, it is advantageous for the elbow.

Secondly, the multi-tube model, the so-called multi-tube and one-die, is that the same diameter pipe should use the same bending radius. That is, using the same set of molds to bend different shapes of the tube shape. In this way, it is beneficial to minimize the compression of special process equipment and reduce the manufacturing cost of the bending mold, thereby reducing the production cost. In general, pipes of the same diameter are only required to have an assembly radius that does not necessarily meet the actual position. Therefore, pipes of the same diameter can be selected from 2 to 4 bending radii to meet actual needs. If the bending radius is 2D (where D is the outer diameter of the tube), then 2D, 2.5D, 3D, 4D can be used. Of course, this ratio is not fixed bending radius, the actual situation of the aircraft or engine should be selected, but should not be selected too large radius. The specification of the bending radius should not be too much, otherwise the benefits of multi-tube and one-mode will be lost.

The same bending radius (ie, one tube and one mold) and the bending radius of the same specification tube are standardized on one tube (multi-tube and one mold), which is the characteristic and general trend of the current foreign catheter design modeling, mechanization and automation. Instead of the inevitable result of manual labor, it is also a combination of designing advanced processing technology and advanced processing technology to promote design.

As an emerging control system, the embedded system has obvious control advantages in the industrial field. As a low-power, cost-effective, and highly flexible control core, the embedded system is bound to replace the traditional industrial computer It plays an indispensable and important role in machine control. Embedded measurement and control system used in industrial field, especially in the field of CNC pipe bending machine, will definitely bring a new round of revolution to the development of CNC tube bender!

First, the hardware selection of pipe bending machine measurement and control system

In the process of designing an embedded measurement and control system for a pipe bender, the choice of embedded microprocessor is particularly important. The foundation of an embedded microprocessor is the CPU in a general-purpose computer. In order to meet the special requirements of embedded applications, although the embedded microprocessor is basically the same in function as the standard microprocessor, various enhancements have been made in terms of operating temperature, anti-electromagnetic interference, and reliability. Embedded microprocessors have the advantages of small size, light weight, and low cost.

Selection of Servo Motor for Pipe Bending Machine

管 The servo motor of pipe bender is also called executive motor. In the automatic control system, it is used as an actuator to convert the electric signal received into the angular displacement or angular velocity output on the motor shaft. Divided into DC and AC servo motors, the main feature is that when the signal voltage is zero, there is no rotation, and the speed decreases uniformly with the increase of torque. Servo motors mainly rely on servos to locate by pulses. When a servo motor receives a pulse, it will rotate the angle corresponding to 1 pulse to achieve displacement. Because the servo motor itself has the function of sending pulses, each time the servo motor rotates one At the angle, a corresponding number of pulses will be sent, so that it echoes the pulses received by the servo motor, or is called a closed loop. In this way, the system will know how many pulses are sent to the servo motor, and how many pulses are received at the same time. , It can control the rotation of the motor very accurately, so as to achieve accurate positioning, which can reach 0.001mm.

With the continuous development of science and technology, the types of three-dimensional numerical control pipe benders have become increasingly diversified, and the pipe bending performance has also been greatly improved. The application of microcomputers, single-chip computers, programmable controllers, advanced AC servo systems, new hydraulic components and hydraulic technology makes the functions of three-dimensional CNC pipe bending machines more perfect. And CNC 3D CNC pipe bending machine will be the main equipment of modern pipe production.

During the rolling process of the workpiece by the 3D CNC pipe bender, the rolled workpiece is bent due to uneven hardness of the surface layer under the effect of external force. The bending rotation center is high, and the rolling pressure is large, and the plastic deformation is also large, so that the degree of bending of the workpiece is further increased. This phenomenon is particularly prominent when rigid rolling tools are used.

Today, our experts from Taiwan and Machinery mainly talk to you, what is the load force of 3D CNC pipe bending machine bending? When the three-dimensional numerical control pipe bender is bent, the trolley is used as a load to be pulled forward by the pipe. In order to improve the bending, avoid excessively thinning the wall thickness of the bent part of the pipe, reduce springback, and add a booster device.

When bending, the die not only compresses the tube, but is pushed forward by the boosting force to form a side thrust to assist the bend. The pipe bending arm and the bending main shaft are integrated into one body, the pipe bending die shaft can be replaced, and the clamping die moves up and down. This not only has a reasonable structure, increases the strength of the mechanical part, but also has a simple structure, which simplifies the electrical circuit. There are many industries where 3D CNC pipe benders are applied, mainly in the decoration industry, automotive industry, power construction, railway construction, boilers, bridges, ships, and pipeline laying and transformation.

Correctly operating the 3D CNC pipe bender can ensure the personal safety of the operator, and is very conducive to extending the service life of the 3D CNC pipe bender. The pipe bend not only avoids the collision between the trolley and the die, ensures the successful completion of the last bend, but also reduces the material head clamping loss and reduces the production cost.

Pipe processing machines, pipe bending machine, hydraulic tube bending machine, metal circular saws, pipe cutters, pipe end forming machines, mechanical presses, hydraulic presses, fully automatic pipe benders, high-speed presses, plate rolling machines, shear folds Sheet metal processing equipment such as machine tools and roll forming production lines have made significant progress in terms of processing accuracy, reliability, technical indicators, energy saving and emission reduction, and pleasantness. The new product development capabilities and market competitiveness have been greatly improved. So what is the relationship between the pipe bending machine value and the three-dimensional coordinate data? Now let's listen to the stage and the mechanical experts.

Improving security capabilities. First, we must actively promote lean management of pipe bender production. Deepen the state maintenance of power transmission and transformation equipment, and increase the application of advanced technologies and equipment such as live detection. Comprehensively implement equipment status inspections, and actively expand the integration of power transmission and operation and maintenance pilots. The second is to strengthen the research on the company's operation control technology. In-depth analysis of the operating characteristics and structural changes of companies such as UHV commissioning, optimizing the company's operating methods, deepening the application of intelligent company scheduling technology support systems, and improving the company's level of safe and economic operation.

The processing value of the pipe bending equipment can of course be converted into three-dimensional coordinate data and can be marked on the three-dimensional diagram, but it should be noted that the rebound value of the material must be distinguished by +-, and the direction and angle of the pipe rotation can also be changed. It is noted in the three-dimensional icon, but in production and use, it is necessary to pay attention to the distinction of actual values. In the CNC and NC2 pipe bending equipment, the example of converting the pipe bending machine processing value into three-dimensional coordinate data has been used for a long time. The 3 coordinates usually used by pipe benders are X.Y.Z, and the coordinates displayed on CNC pipe benders are Y.B.C. These two kinds of coordinates can be directly converted to each other on the pipe bender.

With the advancement of technology and the increase of labor cost, unmanned factories are gradually popularized worldwide. To build an unmanned factory, the core equipment is CNC machine tools and industrial robots. Digitalization and intelligence in manufacturing are at the core of a new round of industrial revolution, including product innovation, manufacturing technology innovation, and industrial model innovation. Deeply reforming the production mode and industrial form of the manufacturing industry is the core technology of the new industrial revolution.

Today, our experts in Taiwan and machinery talk about the various pipe bending techniques and methods of pipe bending machines for bending various profiles and guide pipes used in aircraft. We know that the numerical control technology of pipe bending machines can not only make the bending quality of catheters. With a reliable guarantee, and the production efficiency has been greatly improved, the appearance of the manual pipe bender has changed. However, due to the complicated spatial geometry of the catheter, it is difficult to accurately express it with design drawings; and it is also very difficult to measure the tubular standard sample, so editing the "pipe bending program" has become the current use of CNC pipe bending New problems to be solved.

At present, the pipe bending program can only be recorded by trial bending one by one-preliminary data-trial bending the entire tube shape-correction data-finally determining the data. In this way, not only a certain number of tubes are scrapped, but also the efficiency is very low.

In order to find a better way to bend the guide pipe of the new pipe bender, we use the vector pipe bending technology of the CNC automatic pipe bender. Based on the vector theory, the center line of each straight segment on the pipe shape is regarded as a series of spaces. Vector, using the basic concepts and operations of vectors, to accurately calculate "incremental tubular data" to control vector pipe benders. The bent pipe can also be automatically inspected, and compared with the standard pipe shape data, the "difference" is calculated, and the "difference" is used to modify the pipe bending program to obtain a new pipe bending program, and then bend the next one. Pipe, this is the basic characteristic of vector pipe bending technology.

The so-called vector is a quantity with size and direction. A directed line segment in geometry is an intuitive vector. From the definition of two vectors being equal, we can know that after moving a vector in parallel, it is still a vector equal to the original vector. So the starting point of the vector can be placed at any point in space.

The pipe bending machine and cnc tube bender manufacturer industry is a manufacturer and servicer of the metal pipe bending machine industry. Every move of the pipe bending industry affects the nerve of the pipe bending machine industry. Because the pipe bending machine should do a good job for the pipe processing industry and provide better equipment. China's pipe bending machine is on the way to further open the international market, and is advancing towards high-quality production, high-tech research and reliable services. The industry should fully realize new, automated, multifunctional integrated, low-carbon and environmentally friendly pipe processing. system.

Although China's pipe bender industry has achieved certain results, we should also see the bottlenecks encountered in the development of our country. Technical innovation has always been a flaw in the domestic pipe processing machine tool industry. Compared with foreign pipe benders and pipe cutting machine tool processing industry, China's pipe bender industry is significantly behind in terms of manufacturing technology, and there are serious shortcomings in terms of technical level and operating speed. If we want to solve this problem, we must take strong countermeasures.

At present, most pipe processing enterprises such as pipe benders and pipe end forming machines in China lack a sense of independent innovation. Can't do in-depth research and development of technology. This restricts the development of pipe benders. In order to solve this phenomenon, innovation is the key. Enterprises should increase technical support, combine development and innovation in the pipe bender industry, define future development goals, and accelerate the development of pipe bender technology while ensuring product quality. Because China is currently underdeveloped, most companies have short-term development strategies and technological innovation is particularly slow. Therefore, relevant government departments should give support to jointly promote the development of the pipe bender industry.

As an important processing tool, pipe bending machine for pipe processing machinery will play an important role in the development of China's high-tech industry in the future. Therefore, both the enterprise and the government should do their best to promote the development of the pipe bender industry in China.

With the smooth transfer of government, policies are becoming more and more stable, and economic development is the last word. The focus of the central decision-making level will shift to domestic economic growth. The realization of economic growth must first be driven by our equipment manufacturing industry, and then the machine tool industry such as pipe bending machines and automatic tube shrinking machines will achieve rapid growth.

The perfect development of industrial automation not only enhances the development momentum of the industry, but also reduces the burden of human labor in some new areas. The future factory production mode will become more efficient and concise. In fully mechanized production, it will not only improve the industry Standardization of quality is more quality in quality and technology. The level of industry depends on equipment manufacturing, and the level of equipment manufacturing depends on machine tools. How many times this sentence has been questioned, it has been verified again and again. The machine tool is called the "mother of industry", and all module parts in the industry are produced by it. The product quality directly restricts China's industrial development level. The transformation of the manufacturing industry has begun in all directions, and the machine tool industry is really pushed to the forefront.

 "Internet +" is an upgraded version of the integration of the two industries. The Internet is taken as the core feature of the current development of information technology, and it is fully integrated with service industries such as industry, commerce, and finance. The key is innovation. Only innovation can make this + truly valuable and meaningful. Because of this, "Internet +" is considered to be a new form of Internet development and a new business format under Innovation 2.0, and a new form of economic and social development driven by Knowledge Society Innovation 2.0. In popular terms, "Internet +" is "Internet + various traditional industries", but this is not a simple addition of the two. Instead, it uses information and communication technology and the Internet platform to allow the Internet to deeply integrate with traditional industries and create new ones. Develop the ecology and change their production methods and industrial structure with their own strength. "Internet + Industry" has become an important breakthrough for traditional industries such as machine tools.

For the tube bending machine and pipe processing manufacturing industry, in recent years, the global Internet-based development model of products has formed a new round of marketing system, which will completely overturn the traditional business methods in the past. With the vigorous development of the Internet by Taiwan and Machinery, our current product marketing channels are basically based on the Internet for product promotion and marketing, and some sales offices in the past have now transformed into our products. The post-maintenance service point is complemented by online promotion and offline experience. The post-maintenance of the pipe bender products will be arranged by the company directly in the past, and the maintenance service will be more complete and timely.

China is the world's largest machine tool producer and the world's largest importer of high-end machine tools--this reflects a current situation in China's machine tool industry: high-end failure and low-end surplus.

The combination of the pipe bender industry and the Internet will be a long-lasting process; the re-engineering ability of the Internet will give enterprises more innovative challenges. This is not a road that two companies can explore. It requires our entire industry to go hand in hand. Find out what really suits the Chinese machine tool industry, and can quickly catch up with foreign innovation.

In the bad market environment of low-price competition, such as CNC machine tools such as cnc pipe benders and cnc hydraulic tube benders, many domestic manufacturers and brands are not prominent, lack of technological innovation, rely heavily on advanced foreign technology, and lack core competitiveness. At the same time, the rise in labor costs and the rise in raw materials have also greatly increased the cost pressure of many enterprises.

Although the machine tools in the pipe bender industry in China started late, they are supported by the downstream machinery processing and other related industries. The industry as a whole is developing rapidly and the scale is also growing. But for the time being, although many companies have improved their strength, they are still in an extensive business model. Due to excessive competition, the homogeneity of products is serious, resulting in narrow profit margins, and also restricts the development of many enterprises. So how to obtain the automatic pipe bender with less investment is a question worth exploring. Can you upgrade the original machine without buying a fully automatic pipe bender? The answer is yes. The experience of upgrading and reforming for several years tells us that this is very promising, not only good practical performance and short cycle, but also can save a lot of money.

Questions that need attention in CNC upgrade, what kind of machine tool is suitable for CNC upgrade and remanufacturing? Experience has shown that vertical and horizontal lathes (especially large vertical and horizontal lathes), gantry milling upgrade NC gantry milling, gantry planer upgrade Upgrading of horizontal boring and milling machine to CNC horizontal boring and milling machine and vertical and horizontal grinder to upgrade CNC grinding machine have better effects.

CNC upgrade must be redesigned and remanufactured first to make it meet the requirements of CNC. Simply adding servo motors and numerical control systems cannot achieve the purpose of upgrading. To do this, generally do the following:

Replace the original trapezoidal lead screw with a ball screw to improve accuracy, reduce friction, grind, scrape and grind the guide rail, or use the linear rolling guide to refine the spindle system, improve the accuracy of the spindle, design an automatic cooling chip removal system, and increase the degree of machine automation when necessary Increase the tool change mechanism-the tool magazine manipulator designs and manufactures an automatic lubrication system.

The CNC system and servo system should be determined and selected during the transformation. The function of the CNC system is not as good as possible, and the system with more functions is generally more expensive. The domestic system and the imported system should be selected according to the needs. At present, there is still a gap between domestic systems and imported systems. Generally, imported systems are better for large-scale high-precision equipment. However, the domestic system has made great progress in recent years, and it can be used reliably for general lathes and milling machines. The servo motor first selects the AC servo motor.

的 The choice of remanufactured CNC upgrade contracting company is also very important. To choose a company that has passed the certification certification, the current remanufacturing industry is still very unregulated. The prices of different companies for the same machine tool modification vary widely, and sometimes the difference is as high as-times. Fixed sites, companies without a stable technical team cannot do remanufacturing. A good remanufacturing enterprise must have strong electromechanical design capabilities and certain processing and manufacturing capabilities.

Both the platform and the fully automatic pipe bending machine generated by the machine have a modular, open, flexible and unified structure, providing a visual interface and network integration functions, with multi-channel and multi-NC axis functions, suitable for all processes. In addition, high-end hardware such as ultra-high-speed processors using the latest chip technology and optical fiber transmission technology have been applied in the new CNC system, which has greatly improved the performance of the CNC system. The most important thing is that the NC system it is equipped with is more suitable, and the operation interface of this system is very respectable. Today we mainly talk about what is the rolling straightening method of pipe bender?

管 The pipe bender can use the plastic deformation of the metal under the external force during the rolling process to change the internal stress to straighten the shaft and rod workpieces with better rigidity.

During the rolling process of the workpiece by the pipe bender, the rolled workpiece is bent due to uneven hardness of the surface layer under the effect of external force. The bending rotation center is high, and the rolling pressure is large, and the plastic deformation is also large, so that the degree of bending of the workpiece is further increased. This phenomenon is particularly prominent when rigid rolling tools are used.

The method of rolling straightening is to check the radial runout of the workpiece after the first rolling of the workpiece, mark it everywhere, and use a four-jaw chuck to adjust the recess of the workpiece to the height of the turning center of the machine. It is proportional to the size of the workpiece bending, and then rolled a second time, then use a dial indicator and adjust the jaws of the four-jaw chuck to correct the workpiece. Then use a dial indicator to check the bending condition. If it is still bent, use the above method to adjust the workpiece and perform the third rolling until the straightness required by the workpiece is reached.

刀 The length of the knife travel after the second time should be based on the specific situation. Table and mechanical pipe bender experts suggest that rolling straightening is generally performed during the rolling process of the workpiece. This will not only damage the surface of the workpiece, but also cause the outer surface of the workpiece to be rolled uniformly. , So there will be no dead bends, which is convenient for operation.

In the past year, the company has been improving and upgrading various pipe bending machine products. In order to achieve the overall development of the pipe bending process and the production efficiency of pipe bending equipment, we have carried out a number of technological revolutions on the pipe bending machine products. The improvement and promotion of the pipe bending process make the pipe bending process of the small-diameter pipe fitting and the large-diameter pipe fitting no longer complicated.

In the use of hydraulic pipe bending machine equipment customers, the most common problem failure is nothing more than that the pipe bending machine cannot bend or clamp and a component cannot be used normally. If there is no pressure problem after the pipe bending machine starts, we should Check if there is any problem with the hydraulic oil used on the pipe bending machine, or the inside of the case is too dirty for the oil pump to suck in the oil. Under the premise that the power cord is not replaced under normal conditions, the starter motor is running normally, and the oil pump will not work due to reverse rotation. .

If the oil pump inlet of the motor is running normally, we should check its solenoid valve. First, check the relief valve without pressure. After disassembling the relief valve, check if there is any garbage such as iron pins. The spool is stuck. After disassembling the solenoid valve, use gasoline or kerosene to clean the inside. After cleaning, use a gas nozzle to blow off the remaining gasoline or kerosene, and then restore and install it according to the original steps.

Hydraulic pipe bending machine equipment can work normally without pressure. After excluding oil and motor faults, there are only solenoid valve problems and electrical problems. However, in the manual mode, you can press any action and the overflow valve will display. If the work lamp is not on, the appliance has a problem. If the work lamp is on, the appliance is normal. You only need to disassemble and clean the relief valve to eliminate the fault.

Suzhou Wonsten - China pipe and tube bending machine manufacturer

We all know that the working principle of the pipe bending machine is that the high-pressure oil output by the electric oil pump is sent into the working cylinder through the high-pressure oil pipe. The high-pressure oil pushes the plunger in the working cylinder to generate thrust and bend the pipe through the pipe bending component. The general structure of the pipe bending machine: The pipe bending machine is generally composed of electric oil pump, high pressure oil pipe, quick joint, working cylinder, plunger, pipe bend parts (including upper flower plate, lower flower plate, die head, roller). Then, in order to make the pipe bending machine run reliably, we need to understand some electrical safety measures of the pipe bending machine. The following table and mechanical experts will explain to you:

1. The power supply of the pipe bending machine must be three-phase and grounded in accordance with local power regulations.

2. The power supply mark should be displayed on the machine and control box to warn the staff working in the power system.

3. The personnel who do the power maintenance and inspection of the pipe bending machine must be trained by the professional knowledge of electric power. Please confirm the circuit diagram of the preparation line before the maintenance.

4, limit switch and other protection equipment, it should not be short-circuited or bypassed.
