Abstract

The invention discloses a double-acting spacial warped surface sealing sliding plate piston pump. The piston pump comprises a left pump cover, a left end cover, a left rotor, a right rotor, a right end cover, a shaft, a sliding plate, a pump body, a safety valve, a valve deck and a right pump cover; the left rotor and the right rotor are arranged on the shaft; the opposite surfaces of the left rotor and the right rotor are both warped curved surfaces; the sliding plate is arranged between the left rotor and the right rotor; a sliding plate balancing hole is formed in the middle of the slidingplate; a high-pressure drainage hole is formed in the pump body and is a semicircular hole; the valve deck is fixed to the upper end of the pump body through a bolt; the safety valve is arranged in the valve deck and comprises a spring, valve plates, a valve rod and a valve pocket; the valve rod is sleeved with the valve pocket, and the valve pocket is sleeved with the spring, the valve plates arematched with the two ends of the spring; and a balance hole is vertically formed in the right side of the safety valve. According to the piston pump, one pair of rotors with the warped curved surfaceis utilized to enable the space to warp so that the volume can be changed; sealing of the volume can be ensured through the sliding plate; and the outlet pressure can be prevented from being excessively high through the high-pressure drainage hole and the safety valve.

Description

【Technical field】 [0001] The invention relates to the technical field of piston pumps, in particular to the technical field of a double-acting space twisted surface sealing slide plate piston pump. 【Background technique】 [0002] A pump is a machine that moves or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali liquid, emulsion, suspoemulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids. The structure of the existing pump is complex, and the high-pressure liquid at the outlet is prone to damage the pump operating system. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a double-acting space-distorted surface-sealed slide plate piston pump, which uses a pair of ro...
