Atlas Copco 0634100078

Atlas Copco 0634100078,The material of Atlas Copco seals is selected based on the working environment. Common types include: Polytetrafluoroethylene, which has the characteristics of high temperature resistance, corrosion resistance, and low friction coefficient, and is suitable for high-speed rotating shaft seals. It is mainly used for shaft seals of oil-free screw compressors and sealing in high-pressure environments. Nitrile rubber material has good oil resistance and low cost, but its temperature resistance is poor. It is mainly used for valve plates of piston machines and sealing gaskets of crankcase.

Application scope: Depending on the type of compressor. PTFE bushings are used for the piston shaft seal in screw compressors, while metal graphite gaskets are used for high-temperature areas. For piston compressors, NBR or fluororubber sealing rings are used for the cylinders and valve plates; PTFE oil seals are used for the crankshaft. For centrifugal compressors, asbestos-free gaskets are used for the oil tank and end cover seals.
