wear, lubrication, vane-slot
The reason for the abnormal wear between the vane-slot and the vane in the rotary compressor is analyzed in this paper. Firstly, the influence of lubrication at the clearance, the machining equipment accuracy and oil circulation (oil flow rate) is analyzed. Then the material characteristics including the hardness of the vane and vane-slot, the surface treatment of the vane and the deformation of the vane-slot after welding are discussed. After we find the main correlating factors, we will examine the results from the experiments. Eventually, problem of the abnormal wear is solved by inducing an innovative oil circulation.
