Matters needing attention when the oil-free air compressor shuts down and starts up

22KW screw air compressor


  1. During shutdown, if possible, heat the air compressor as much as possible; if not possible, try to cover the compressor with plastic cloth or other shelters to prevent wind and snow.


  1. When the air compressor unit is working, the temperature is relatively high; after stopping, due to the low external temperature, a large amount of condensed water will be generated and exist in the pipeline. If it is not discharged in time, the cold weather in winter may cause blockage, freezing and cracking of the exhaust pipe of the air compressor and other equipment. Therefore, after the air compressor is shut down and cooled in winter, it is necessary to pay attention to emptying all the gas, oil and liquid water in the compressor and pipeline.


  1. After the holiday shutdown, the operator should turn off the power, open the drainage and sewage valves, and try to rotate the coupling quickly by hand in the direction indicated by the arrow to make the body rotate quickly and discharge the water in the body as much as possible.


  1. Please check all kinds of valves opened before the holiday before the next start-up after the holiday. Before starting the machine (power off), whether the coupling is operated normally by hand, and the machine can be started only after there is no abnormality.


  1. Attention should be paid to the instant start-up. Because the ambient temperature is too low, the fluidity of the lubricating oil is weakened, which will cause damage to the body. If possible, increase the ambient temperature before starting the machine. Pay close attention to the oil injection pressure at the moment of starting up, some machine gears run at a very high speed, if the oil is not filled in time, the gears may be easily damaged).


  1. It is not recommended to use the automatic operation function of the air compressor in an extremely cold environment.
