Belt conveyor is the use of friction to convey the dynamic, with belts, steel belts, steel fiber belts and chemical fiber belts as a kind of compliance with the transmission of materials and traction operations.

Due to the heavy rain and humidity in some areas recently, in order to avoid long-term power failure and the impact of wetting on the inverter, the following points can be used as various precautions before customers resume production: 1. Look inside the electrical cabinet, e.g. ...

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

It is hoped that Sunland inverter is mainly used in three-phase asynchronous AC motor to control and adjust the motor speed. Sunland inverter is mainly composed of microprocessor, including rectification, filtering, inverter, brake, drive, detection, etc. In order to achieve the purpose of changing the power supply voltage, according to the actual needs of the motor...

1. Make proper grounding After a detailed investigation of the site, we can see that the grounding situation on the site is not very ambitious. The correct grounding can not only be useful for the system to press the external disturbance, but also to reduce the disturbance of the equipment itself to the outside world, which is the most useful for dealing with the disturbance of the inverter.

The general voltage in industry is 0... 5(10)V or current 0(4)... 20mA is used as an analog signal transmission method, and it is also a method often used by program control machines. So what is the difference between the transmission method of voltage and current, and when to choose what method, the following will be briefly introduced.

1. The power-on trip or the main power terminal part of the inverter shows a spark. Detection method and discrimination: disconnect the power line, check whether the input terminal of the inverter is short-circuited, and check whether the DC side terminals P and N of the central circuit of the inverter are short-circuited. It may be due to a damaged rectifier or a central ...

1. Discrimination The inverter power module mainly includes IGBT, IPM, etc., check whether the appearance has exploded, and whether there are ablation marks between the terminal and the connected printed board. Use a multimeter to check whether C-E, G-C, G-E have been passed, or use a multimeter to measure whether the resistance of P to U, V, W and N to U, V, W is inadequate.

In the process of repairing the switching power supply, the step-down method can be selected. The method is: by connecting the power plug of the display to a communication voltage regulator, and then adjusting the output voltage of the voltage regulator to about 100V, and then repairing it with electricity, and gradually improving the power supply voltage for repair. ...

Dry-type transformer is a kind of power equipment, and under normal circumstances, dry-type transformer also requires a certain amount of overload, that is, the workload beyond its working ability. So what about the overload of dry-type transformers and how to influence them? ...

Hope Senlan inverter control panel button function diagram 1. The "FUNC/DATA" button is a programming key, press this button once to convert the operation mode, and press it again to read and write the utility code. 2."S ...

At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

1. Why can the rotation speed of the motor be changed freely? The unit of motor rotation speed: r/min the number of rotations per minute, can also be expressed as rpm. Example: 2-pole motor 50Hz3000 [r/min] 4-pole motor 50Hz1500[r/min] Conclusion: The rotation of the motor ...

Voltage Space Vector (SVPWM) Manipulation Method: It is based on the premise of the overall generation effect of the three-phase waveform, with the intention of approximating the ideal circular rotating magnetic field trajectory of the motor air gap, generating the three-phase modulation waveform at one time, and controlling it by approaching the circle with inscribed polygons. In practice, ...

1. Plan a special inverter room When the power of the inverter is large or the number is large, a special inverter room can be planned. The doors, windows and cable holes in the room need to be sealed to avoid dust ingress; It is necessary to plan air filtration equipment and circulation channels to adhere to the normal indoor air ...

What is a frequency converter? Variable Frequency Drive (VFD) uses inverter technology and microelectronics to change the operating power frequency of the motor to control the power control unit of the communication motor. The inverter is mainly composed of rectifier (from communication to DC), inverter, inverter (from DC to communication) ...

1) Operating temperature: The inverter is a high-power electronic component, which is simply affected by the operating temperature, and the general temperature requirement is 0 - 55. However, in order to ensure the safety and reliability of the operation, it is necessary to consider freeing up space when using, and it is best to control it below 40. The inverter generally requires the device to operate ...
