The butt welding machine should be settled indoors, and should have a reliable grounding or zero connection, when a plurality of butt welding machines are connected to each other, the distance from each other shall not be less than 3m, and they should be connected to different corresponding power grids, and should have their own knife switches. Before welding, the pressure of the butt welder should be checked and determined.

21。 The unit is overheating The radiator in the unit is equipped with a temperature switch (normally closed point), and when the temperature exceeds 85°C, the normally closed point of the temperature relay is disconnected, and the unit is overheated and faulty. Check whether the cabinet top fan is working properly, whether the unit cabinet fan switch is tripped, and whether the filter screen is blocked.

1. Air switch Air switch is also called air circuit breaker, referred to as air open, is an indispensable component of the control cabinet, usually from the outside into the cabinet of power supply, must go through the air open, in order to reach the inside, the function of air open in addition to the power supply, more as short circuit protection and overload protection...

Transportation power, urban rail responsibility. With the vigorous development of emerging technologies such as 5G, cloud computing, big data, and artificial intelligence, more innovative technologies are accelerating the empowerment of urban rail transit, and smart urban rail is ushering in a "golden age" of development. As a deep cultivator in the field of smart urban rail, Hollysys adheres to technological innovation.

1. The CPU is abnormal When the CPU is abnormally alarmed, check all the devices connected to the internal bus of the CPU unit. The specific method is to replace the potentially problematic units sequentially, find out the problematic units, and deal with them accordingly. Second, the memory is abnormal Memory anomaly alarm ...

1. Understand the type of variable frequency load The correct selection of the frequency converter is very critical for the proper operation of the control system. When selecting a frequency converter, it is important to fully understand the load characteristics driven by the frequency converter. In practice, production machinery is often divided into three types: constant torque load, constant ...

Laser spot welding machine, also known as resistance welding machine, is usually divided into three categories according to the nature of the welding power source: 1. AC spot welding machine; 2. Energy storage spot welding machine; 3. DC spot welding machine. 1. AC spot welding machine Precision AC spot welding machine generally refers to the spot welding machine with a power of less than 16KVA.

Precautions for maintenance of high-voltage inverters 1. Carefully monitor and record the display parameters on the man-machine interface of the inverter, and reflect the abnormality immediately 2. Carefully monitor and record the ambient temperature of the inverter room, and the ambient temperature should be between -5 °C and 40 °C. Phase-shifting transformers ...

1. If there is a sharp acceleration or deceleration, please extend the acceleration and deceleration time. 2. Avoid rapid increase in load. 3. Check whether there is a short circuit in the UVW of the motor terminal. 4. The module is damaged, and the drive circuit is damaged, resulting in an overcurrent alarm. ...

What aspects should be paid attention to in the application and protection of AC arc welding machine: (1) It should be used according to the additional welding current and load continuation rate of the welding machine, and should not be overloaded. (2) The welding machine is not allowed to be short-circuited for a long time. (3) The regulating current should be operated at no load. （4） ...

1. Intelligent network The intelligent inverter does not need to set a lot of parameters when it is used, and it has the function of fault self-diagnosis, which has high stability, high reliability and practicability. The Internet can be used to realize the linkage of multiple inverters, and even the inverter complex in the factory.

1. Select the inverter according to the load characteristics A: Fans and pumps are the most common loads: the requirements for the inverter are the simplest, as long as the inverter capacity is equal to the capacity of the motor (air compressors, deep water pumps, sediment pumps, and fast-changing music fountains need to increase their capacity). ...

1. External equipment failure. Such faults come from external devices such as various sensors, switches, actuators, and loads. The failure of this part of the equipment will directly affect the control function of the system. This type of failure is usually caused by the quality and longevity of the equipment itself. 2. System failure ...

With the rapid development of the machinery manufacturing industry, the traditional general machine tool can no longer meet the changing parts processing needs of the shopping mall. CNC machine tools have undeniably become the mainstream processing equipment of today's machinery manufacturing. In response to the special application needs of the machine tool industry, Megmeet has launched the MV series of high-function ...

1) Hand arc welding (STICK) Shielded Arc Welding (abbreviated SMAW) in English, The principle is: the arc occurs between the coating electrode and the base metal, and the welding method of arc thermal ablation electrode and base metal is used. The outer layer of the electrode is covered with solder, which is dissipated in case of heat.

1. Leakage protection switch Phenomenon: The leakage protection switch of the equipment is activated when the inverter is powered on or running Measures: When the inverter drives the motor, the leakage value is larger than that of the non-inverter system, and the leakage protection value of the leakage protection switch is required to be 150mA and above, and the action delay is ...

1. The Megmeet rectifier module is damaged It is usually caused by grid voltage or internal short circuit. In the case of sweeping the internal short circuit, the rectifier bridge is replaced. When dealing with faults on site, we should focus on checking the status of the user's power grid. Such as the power grid voltage, whether there is an electric welding machine, etc.

1. The inverter must be selected correctly. 2. Read the product manual carefully, and wiring, installation and use in accordance with the requirements of the manual. 3. The inverter device should be reliably grounded, and the radio frequency interference should be suppressed to prevent the inverter from causing electric shock due to leakage. 4、 ...
