Talk about centrifugal air compressor

 

 

Centrifugal air compressor is a mechanical device for conveying gas, which is composed of rotor, stator and bearing. The rotor consists of the main shaft, impeller, coupling, etc., and sometimes also includes the shaft sleeve and smooth disk. The stator consists of a housing, an interstage seal and a shaft end seal, an intake chamber and a volute chamber. Centrifugal air compressor is a kind of turbine air compressor, which is completely different from the working principle of piston air compressor and belongs to the rotating blade machine.

In view of the increasing operating load of mechanical equipment in the chemical industry, the failure rate of centrifugal air compressor also increases significantly: 1. The oil pressure drops suddenly 2. The air outlet flow rate decreases 3. The exhaust temperature cooler temperature is too high 4. The bearing temperature is too high, the bearing vibration is too high, and the cooling effect of the cooler is poor

Routine maintenance of centrifugal air compressor:

Regularly check the functional status of the mechanical system of the air compressor, find hidden dangers through the equipment debugging method, and deal with the operation failure in advance; On the other hand, check and remove major components such as bearings and coolers to determine whether mechanical parts are worn. Lubrication and other problems, timely supplement lubricating oil to improve system operation efficiency; For some aging compressor equipment, if necessary, you can replace the new equipment or components, which is also an effective way to prevent failures.
