一、检测与调整 在进行螺杆主机的装配调试过程中,常可看到因轴承轴向游隙值过大并难以调整或是两转子的轴向游隙值不一致而使排气端及齿形面间气体泄漏过大,以致降低了主机的排气量及气压的情况;我厂的中压螺杆主机过去一直是采用在轴端面加垫并直接在主机上来调整轴承组的轴向游隙值的,装配时需要凋整,检测几次才能完成,调试起来很不方便,且主机经 First, the detection and adjustment During the screw host assembly and debugging process, you can often see the bearing axial clearance is too large and difficult to adjust or inconsistent axial clearance of the two rotors and the exhaust end of the tooth Gas leakage between the surface is too large, resulting in reduced the host of displacement and pressure conditions; I plant in the pressure screw host has been used in the shaft end pad and directly on the host to adjust the bearing group axial clearance value , The assembly needs to be adjusted, testing several times to complete, it is inconvenient to debug, and the host by
