balanced piston sleeve for compressor

    Screw refrigeration compressor balanced piston sleeve

    The balancing piston gives the synchronous gear and the rotor an opposite axial force under the action of lubricating oil pressure, so that the compressor runs smoothly; the balancing piston is fixed to the end of the suction side of the active rotor by bolts (or keys). The piston sleeve rotates with a barrel of the rotor and bears the oil pressure to balance part of the axial force. The function is to extend the service life of the thrust bearing. The balance piston and balance piston sleeve must be replaced when they are seriously worn.
