Used air compressor and hand DTH drilling leasing, recycling, sell! The need to overhaul Screw Compressors host and working screw compressor host running between the screw and the screw between the screw and the host of the housing and the front and rear ends are not in contact theory, Shanxi Kisan Air Machine Leasing Co., Ltd. with you to analyze the reasons, for three reasons: ① film while a host formation so that no direct contact between the screw and the screw, of course, the host just starting or stopping a short time because the film has not yet formed or film poor state, there will be some direct contact between the screw and the screw; precision screw ② host housing ensures proper clearance between Gansu old air compressor leasing assembly screw the host and the host of the housing, the gap size has been taken into account differences in temperature of the host running the screw and the deformation of the housing problem; ③ screw with fore and aft end of the gap is to ensure that according to the technical parameters required when making screw assembly, the size of the gap is also been taken into account when the host is running a high temperature screw differences in the amount of deformation of the front and rear end face of the problem, while the screw radial load and axial compressive load generated by the locating bearing hosts across the bear, no axial displacement of the screw, so end clearance has been further guaranteed.

As the screw compressor effect does not exist in the machine wearing parts, compression due to the characteristics of a pair of rotors and adequate lubrication of the rotor surface structure with a layer of film itself is protected so there is no metal in contact with the phenomenon does not appear worn. So long-term continuous operation of the economy is much better than the piston compressor.
