PISTON-TYPE PUMP PLANT Russian patent published in 2010 - IPC F04B47/06 

FIELD: engines and pumps.

SUBSTANCE: proposed plant serves to pump out edge waters and deposits located at major depth in liquid state. This plant comprises motor (1) coupled with reduction gear (5), converter of rotation of drive shaft (3) in reciprocation of rod (12) linked up with piston (14) moving in cylinder (15). The latter is coupled with flow column (18) with inlet and outlet valves (16), (17). Proposed invention differs from known designs in that motor (1) represents a deep-well pump coupled with reduction gear (5) via starting clutch (2), while reduction gear (5) represents planetary mechanism comprising drive gear (6), planet pinions (7), pinion frame (8), driven wheel (9) rigidly coupled with outer collar (10) of helical rolling bearing (11). Rod (12) represents inner collar of rolling bearing (11). Opposite end of rod (12) is coupled with pinion frame by feedback. The latter comprises tie rod (20), spring (21), double-sided thrust bearing (22) coupled with guides (23) supporting face gear wheels (24), (25), (26), (27). Piston (14) comprises damper (32).

EFFECT: reduced weight, power consumption, piston idling and metal input.
