6 FAQs about [Overload of the main engine of the power frequency screw air compressor]

What are the most prone failures of screw air compressors?

One of the most prone failures of screw air compressors is the overload of the main engine motor. I believe that many companies have similar experiences when using them, mainly due to the following 5 reasons: 1. Loose wiring

What is air compressor overload?

Air compressor overload is a common issue that can result in equipment shutdowns, reduced efficiency, and even damage to the machine. Understanding the causes of overload is essential for maintaining optimal performance and preventing costly downtime.

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 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 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. In this case, the electrical system is easily burned out. This reason is also the most likely to cause more extensive damage.
