As a vane of rubber and plastics professions and a barometer of shopping malls, the World Rubber and Plastics Exhibition has a 350,000 square meter ...

The basic principle of a high-voltage inverter There are two categories of frequency conversion process of frequency converter: AC-AC form and AC-DC-AC form. Now it is mostly in the form of AC-DC-AC, and the following is a brief introduction to the working principle of this form. Three-phase high-voltage electricity enters the high...

1. PLC industrial gateway has rich interfaces and is easy to deploy It supports 4G, 3G, PPPOE, Wi-Fi network, digital IO input and output, and serial terminal communication, providing different access solutions for different applications. 2. Intelligent analysis and efficient access Inline protocol analysis ...

1. Damage to the welding power supply. Due to the high current and high voltage during welding, when the welding current exceeds 20% of the rated value, overcurrent protection will appear, so that the circuit will automatically cut off the power supply. In addition, if the welding time is too long, it can also cause overcurrent. Therefore, we should try our best to ...

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 ...

One. It is difficult to start the arc and easy to break the arc 1. Confirm that the quality of the electrode you use is good, and the poor quality electrode may not meet the requirements of high-quality welding: 2. The welding rod that has not undergone drying treatment is also not easy to arc, and causes the arc to be unstable, so that the welding defects increase, and the welding ...

1. Data backup When carrying out maintenance, we must cut off the power, data backup between power outages is an important link, for the data that needs to be archived for a long time, you can back up the historical trend data to the mobile hard disk, and then turn off the Windows-based operating system (Note...

1. The arc is stable in the field of full current, the spatter is small, and the same welding machine is not only suitable for small current base welding, but also suitable for high current and high deposition rate work 2. Arc concentration and strong penetration. With the same penetration depth, the heat input is reduced by more than 20% compared with other gas shielded welding machines, and the thermal deformation ...

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 ...

5) PLASMA The principle of plasma cutting is: arc discharge between the base metal (including the nozzle in the cutting torch) and the electric in the cutting torch, and use the discharge heat energy to make the compressed gas produce a high-temperature and high-speed plasma arc to fuse the cutting method of the base metal. The small hole of the nozzle ...

1。 How do you distinguish between heavy and light failures? When the fault is light, the system sends out an alarm signal, and the fault indicator flashes. When a major fault occurs, the system issues a fault indication, and the fault indicator is always on. At the same time, a command is issued to break the high voltage and close the prohibition, and the fault information and high voltage are instructed.

1. Fault phenomenon: light voltage abnormal indicator Cause: Due to the slow start-up action, the switch contact is not synchronized. Solution: You can turn the device off and on again. 2. Fault phenomenon: the fan does not rotate, and the abnormal voltage indicator light is lit together Causes ...

1. The circuit board inside the inverter belongs to precision electronic components, which needs to be moisture-proof and dust-proof, and the temperature and humidity are not too high, and cannot be installed on the bare wall, so the inverter should be installed in the middle of the control cabinet; The inverter should be installed vertically, and the installation should be avoided directly above and below ...

When the oscilloscope looks at the current monitoring output of the driver, it is all noisy and cannot be read Cause: The current monitoring output is not blocked from the AC power supply (transformer). Solution: You can use a DC voltmeter to detect and investigate. Servo motor high-speed rotation ...

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. 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. The electrical control cabinet installed with PLC should have a clean and dry environment. Moisture-absorbing dry materials should be placed inside, and the splashing of coolant and oil mist should be prevented. 2. Regardless of the system working or shutdown, the electrical cabinet door should always be closed, and the electrical components should be kept in a good state.

1. Common processing: reset the monitoring timer, perform hardware checks, user memory checks, etc. 2. Program execution: The CPU interprets and executes each instruction in the order of first left and then right, first up and then down, and reads out each relay according to the input image register and the component image register.
