What is the function of screw air compressor protection and early warning

Screw air compressors are now mostly controlled by microcomputers, which are intelligent and convenient to use, and have better protection for the air compressors. As the name implies, the screw air compressor protection and early warning function mainly refers to two types of functions: protection function and early warning function

1. The protection function of the screw air compressor

The main reason is that the computer detects an abnormal signal and organizes the air compressor to start to avoid failure. The specific protection functions are as follows:

(1) Power phase error protection

(2) Power phase loss protection

(3) Three-phase current unbalance protection

(4) Main motor current overload protection

(5) Low or high external voltage protection

(6) High temperature automatic protection

(7) Air supply pressure high pressure protection

(8) Pressure sensor failure protection.

2. Early warning function of screw air compressor:

The early warning function is the parameter information prefabricated on the microcomputer of the air compressor according to the performance of each type of air compressor when the air compressor leaves the factory, to remind the user what should be executed at the corresponding time:

(1) Air filter expiration warning prompt

(2) Oil filter expiration warning prompt

(3) Oil and gas separator expiration warning prompt

(4) Early warning prompt for screw oil expiration

(5) Early warning prompt for motor lubricating oil expiration.
