Faults that may occur in the operation of screw air compressors

During the daily operation of the screw air compressor, failure problems may occur, which is inevitable. Just like a car, it breaks down when it is driven, which is normal.Sudden shutdown, high exhaust pressure, poor start-up and even air compressor stuck during operation may all occur.In view of the above failure problems, summarize the causes and corresponding troubleshooting methods for the majority of users：

The suction pressure is too low, below the low voltage lower limit of the pressure relay；

If the oil pressure is too low, the oil pressure relay will act to relay the power.；

Exclusion method：

Check the cooling volume or cooling air volume of the condenser；

Check whether the power supply voltage is low or the cold load is too large；

2. The exhaust pressure is too high

The scale on the surface of the cooler is too large or the oil is too thick, making it difficult to dissipate heat.；

The valve in the exhaust pipe fails, causing the pressure to be too high；

Check whether the valve is fully open, increase the water supply or check the motor voltage, speed, or whether the transmission belt is too loose；

Let go of the air in the cooling system；

The power supply is disconnected, the fuse is in poor contact, and the fuse is burned.；

The temperature controller fails or fails；

Exclusion method：

Check the starter and wipe the contacts with gauze；

Check the components of the pressure relay or adjust the value；

Fourth, the air compressor is stuck

The lubricating oil is not good, and there are too many impurities, including impurities in the oil, carbon deposits, coking, etc.；

Exclusion method：

Choosing lubricating oil is the key. Choose good-quality lubricating oil and do a good job of oil change and maintenance in time.；

Regularly maintain and overhaul the nose.
