A hydraulic pump has a body with plate covers, movable partitions arranged as diaphragm, those form with the body guide chambers connected by means of mains and gas-distribution slide to boiler and condenser with formation of closed circulation contour and pump that pumps working body in the system. On movable partitions at two opposite sides pistons are fixed, those are placed in cylindrical part of the body. In the middle part of the body partition with central opening is arranged, through it rod goes, this is connected to placed in opposite positions pistons that form with the body and partition working chambers connected to inlet and outlet pipelines by means of valves. In placed in opposite positions pistons closed long grooves are provided. In one groove of the piston a rod of gas-distributing spool is mounted movably, and in the groove of the opposite piston a plunger with central channel is placed, this is rigidly connected to the cover of the body. The plunger with central channel and with the piston long groove forms the pump cavity connected to main pipes by means of suction and discharge valves with boiler and condenser. Such implementation of hydro-pump makes it possible to increase liquid pressure. |
