VACUUM LIQUID RING PUMP Russian patent published in 2008 - IPC F04C7/00 F04C19/00 

FIELD: motors and pumps.

SUBSTANCE: invention relates to mechanic engineering and may be used for development of vacuum liquid ring pumps. The pump contains chamber made of two separated similar sections in the shape of cups. The inner cup diameter is selected as equal to circle diameter describing lattice inlet. Chamber sections are rigidly and tightly fixed to the above lattice. Two sleeves are provided at the ends of chamber sections perpendicular to lattice plate. The lattice is fixed to cup-shaped flange and a wheel is located inside the flange with some shifting from flange axis. The wheel is fitted on the half axle and fixed by dowel and retaining ring. One end of bushing is linked with the body base, whereas the other end is coupled with the main pump flange along its central line. The half axle is located inside bushing and crosses highly heat-conducting washers with recesses. The sealing ring is freely positioned on half axle inside the above washer recesses. The lattice openings for supply and discharge are made by through channels.

EFFECT: simple design, increased time of operation, output and wide choice of materials to be used for pump production.
