Abstract

The invention discloses a three-blade distortion plane equal speed increasing and decreasing hook face volume rotor pump which comprises an abnormal-shaped guide shaft, a pump body, a cover plate, anend cover, a shaft, a rotor, a lining plate, a key and a sliding sheet. The sliding sheet is embedded in the abnormal-shaped guide shaft, the rotor is in key connection to the shaft, the two side faces of the rotor are distortion hook faces which are three-blade distortion hook faces, the distortion hook faces are of double-face structures with three wave crests and three troughs, the difference between the wave crests is 120 degrees, the difference between the wave crests and the troughs is 60 degrees, and the wave crests and the troughs are horizontal planes; a rotor groove is vertically formed in the middle portion of the sliding sheet, and a high pressure drainage groove is transversely formed in the middle portion of the sliding sheet; and a step notch at the lower end of the abnormal-shaped guide shaft is matched with the upper end of the lining plate. The three-blade distortion plane equal speed increasing and decreasing hook face rotor is adopted, the sliding sheet, the symmetrical lining plates and the rotor are used for isolating inlet and outlet cavities of the pump, and the volume is changed through rotation of the hook face rotor with three wave crests and three troughs; and the high pressure drainage groove prevents forming of flowing dead zones in cavities in the left and right ends of the sliding sheet.

Description

【Technical field】 [0001] The invention relates to the technical field of rotor pumps, in particular to the technical field of a three-blade twisted plane equal acceleration and deceleration curved surface volume rotor 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 it is easy to generate a dead zone, thereby causing damage to the pump operating system. Therefore, for pumps with high pressure and low flow, a new type of rotor pump is needed. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in t...
