Atlas Copco 2906073700,The measuring tools in the Atlas Copco rotor inspection kit are usually made of alloy steel to ensure accuracy and durability. For specific components such as rotor sleeves, nickel-based superalloys may be used to withstand high-speed and high-temperature environments. In some new centrifugal air compressors, composite material sleeves are also used, with a metal inner layer and a non-metal outer layer, to balance heat dissipation and suppress eddy current losses. Key parameters, the wear amount at the rotor meshing area, is typically required not to exceed 0.5mm - 0.7mm of the diameter. The scratch standard: the scratch area should not exceed 25mm² and the depth should not exceed 1.5mm. The coaxiality: the radial runout or out-of-balance at the rotor end should generally not exceed 0.010mm. The clearance requirement: the clearance between the rotor and the body is approximately 0.1mm, and the clearance between the rotor exhaust end face and the bearing seat is approximately 0.05 - 0.1mm. The wear grooves on the inner sealing surface of the rotor should be less than 0.1mm.

It is widely used for regular maintenance and fault diagnosis of screw-type and centrifugal air compressors. It is applicable to air compressor equipment in multiple industrial fields such as metallurgy, mining, chemical industry, pharmaceuticals, and power. It is particularly used for verifying the condition of main machines that have operated for more than 15,000 hours, have experienced abnormal sounds or vibrations, or have undergone bearing replacement and other maintenance.
