Working Description
1.	Decomposition of the rotor, cleaning all parts
2.	Screw surface coating of female rotor and male rotor, and the grinding process for coating
3.	Dynamic balance of female rotor and male screw test
4.	of the rotor housing for spraying , grinding
5.	Female screw and male screw and the case will be carried out with the ground screw, and adjust the gap
6.	According to our standard procedures and requirements to replace a full set of bearings, seals , oil seals and other components, adjust the gap between the parts, re-assembly of the rotor ok
7.	General cleaning of the shell exterior, painting, packaging

  Product Photos: Before Overhaul              After Overhaul          The above mentioned are comparison pictures before and after maintenance for high pressure rotor, balancing test data are as follows 1,   Female and male rotor balancing test , installation, gap adjustment, replacing worn parts 2,   The test results is rotor manually running normal , no noise inside 3,   Balancing test standard and results analysis Type YYQ-80 hard bearing balancing machines be used to test and measure the balancing of female and male rotor, using graphic supporting method, selection removing the gravimetric method.   Notice: The equipment must be installed and debugged by the professional engineers specialized in oil-less air compressor, after complete installation,  point-start the host to ensure that gearbox oil supply is sufficient , running unloading more than twenty minutes to ensure the surface breaking in of the rotor, then load operation.    OTHERS FOR REFERENCE ATLAS COPCO Standard major overhaul detailed work content(FOR OIL COMPRESSOR ALSO)
