Basic knowledge of refrigeration compressor

After shutting down, stop for at least 3 minutes before starting again to eliminate the pressure difference between the compressor inlet and outlet. Because in the case of a large pressure difference, the starting torque of the motor will increase, causing the current to rise to a certain level, the protector will act and the compressor cannot continue to run.

Types and functions of adsorbents for drying machines

The working principle of the suction dryer (also known as the adsorption dryer) is to reduce the moisture content in the compressed air by using the characteristics of the adsorbent to absorb moisture. Generally speaking, the pressure dew point of the outlet air of the suction dryer reaches -20℃~-70℃ .

Intake valve cannot open fault

Quanzhou failure analysis In Quanzhou in the past two days, I was debugging an air compressor. I encountered such a problem. The unit was operating normally for the first time. However, after shutting down and turning on, the unit was abnormal and could not pump air. At present, it can be guaranteed that the original electrical appliances are normal.

Introduction to the principle of electric screw machine

One. The electrical control system of the microcomputer controller electric screw air compressor is the key system of the electric screw compressor. Its main function is to reduce the voltage and reduce the starting current when the three-phase asynchronous motor (capacity is greater than 10KW) is started, so as not to generate excessive power in the power supply line. Voltage drop to reduce the impact on the grid.
