ROTOR SLIDING-VANE MACHINE

摘要

The invention relates to mechanical engineering and can be used as rotary gate high-pressure machine with uniform volumetric feed which can operate as a pump or as a hydraulic motor. The invention is aimed at overcoming reasons causing increased power dissipative loss, as well as at reliability increase by creating means of hydrostatic rotor balancing adjustment and mobile packing, resistant to the machine elements wear and working fluid contamination, and also compatible with means of cavitation overcoming in vane chambers. A rotor sliding-vane machine comprises a rotor including working (1) and supporting parts (4) connected via force chambers (6) of variable length so that they rotate synchronously with a possibility of little reciprocal axial movements and tilts. The vanes (8) are located in vane chambers (7) of the working part (1) of the rotor and when the rotor is rotating they cyclically change the degree of protrusion into the annular groove (2) made on the face surface of the working part of the rotor. Between the supporting cover plate (5) of the housing and supporting part of the rotor there are supporting cavities hydraulically connected via the means of local pressures balancing to the force chambers of variable length and cavities of the working chamber in the annular groove of the working part of the rotor. Supporting cavities and force chambers of variable length are made so that pressure forces of the working fluid contained in the force chambers significantly balance pressure forces of the working fluid forcing out the working and supporting parts of the rotor from the working and supporting cover plates of the housing providing just a small tightening required for insulation. Losses for friction and cavitation are reduced and reliability of rotary gate machines is improved.
