The Service and Maintenance of Screw Air Compressor (1)
- Jul 05, 2018 -

The routine maintenance of the screw air compressor is to replace the four components of the screw air compressor air filter, oil filter, oil separator and screw air compressor oil. Good maintenance and maintenance of screw air compressor will bring about twice the result with half the effort. On the contrary, if the maintenance is not timely, the air compressor will make troubles with you from time to time.

1. Replacement of the oil filter of the screw air compressor.

The first run of the new machine is usually 500 hours, and the oil filter needs to be replaced.

It is recommended to replace the oil filter every 2,000 hours. When changing the oil, change the oil filter at the same time. When the environment is bad, the replacement cycle should be shortened. The service life of oil filter and screw air compressor oil has a great relationship with the cleanliness of air filter.

It is strictly forbidden to use oil filter beyond the time limit. Otherwise, the filter element is severely blocked, the pressure difference exceeds the limit of the bypass valve, and the bypass valve is automatically opened. A large amount of waste and particles will directly enter the screw air compressor main machine, causing serious consequences.

2. Service and maintenance of the air filter of the screw air compressor.

The air filter is a goalkeeper that filters out air impurities, and the filtered clean air enters the compression chamber of the screw rotor for compression. The internal clearance of the screw air compressor is only allowed to filter out particles within 15 υm. If the air filter plug is damaged, a large amount of particles larger than 15u will enter the screw main body to circulate, which will not only shorten the service life of the oil filter and the oil separation, but also cause a large amount of particulate matter to directly enter the bearing cavity, accelerate the bearing wear and increase the rotor clearance, and reduce the compression efficiency, even the rotor bites.

Therefore, the air filter should be serviced once a week, using compressed gas, from the inner cavity, blowing dust particles on the outer surface of the air filter.

The air filter is normally replaced 1000-2000 hours. In harsh environments, such as mining, paper, and textile industries, it is recommended to replace the air filter every 1000 hours.
