6 FAQs about [The voltage of the screw air compressor is too high]

What is the normal working voltage of screw air compressor?

The normal working rated voltage of screw air compressor is 380V, which can fluctuate up and down around 5%. This refers to the voltage during normal operation. The transformer is relatively small. When the device is not turned on, the voltage is 400V, but when the device is turned on, the voltage drops to 350V.

What happens if the pressure of the screw air compressor unit exceeds?

The pressure of the screw air compressor unit exceeds the rated pressure. For example, if the actual pressure reaches 0.85MPa, the machine with 0.8MPa is prone to overload. It is recommended to purchase suitable machines according to the company's own needs and not to use equipment beyond the regulations. 5.

What are the problems of screw air compressor?

Contactor failure of screw air compressor The contactor of the screw air compressor is aging, the suction is not good, and the contact surface is small, which causes the current to increase.
