If your Air compressor shutdown by overloaded, please check these 7 cases
The reasons for the air compressor mainframe or motor overload fault are:
The voltage is too low: the rated working voltage of the general compressor is the standard voltage of your country, and the upper and lower limits are allowed to float at around 5%.
2. Loose wiring: Check the input power cord for signs of heat and burn.
3. The unit pressure exceeds the rated pressure: for example, the machine with 0.7MPa, the actual pressure reaches 0.75MPa, it is prone to overload phenomenon.
4, the oil separator is blocked: Do not think that you have not blocked the new things for a long time, the site environment is dirty, the impurities inside the oil and gas barrels are easy to block the oil. One of my customers, using the factory accessories, used less than 3,000 hours, the machine was overloaded and stopped, and the pressure was normal after replacing the new parts.
5, contactor failure: replace the new piece...
6, external pressure sensor failure: zero drift, wiring error, upper and lower limits are not set correctly or reversed, according to different sensors have different setting methods and troubleshooting methods.
7, phase loss, blocking, etc. will cause current overload
