Summary of the invention
The double-acting rotor pump hydraulic booster element radial force imbalance that will solve the utility model causes the problem that stator component surface molded lines is impaired and the hydraulic booster element is easy to wear, reliability is low, the life-span is short, and a kind of hydraulic booster element radial force stress balance, not easy to wear, reliability is high, the life-span is long double-acting rotor pump are provided.
The technical solution of the utility model:
Double-acting rotor pump, comprise the pump housing, stator component, rotor element, the hydraulic booster element, main shaft, described rotor element is installed in stator component inside, the outer rim of described rotor element is evenly equipped with the mounting groove of hydraulic booster element, it is characterized in that: described hydraulic booster element is a rolling slide plate, described rolling slide plate comprises the slide plate body, the both sides, top of described slide plate body are provided with the rolling seat of protrusion, be provided with first compensating groove between described slide plate body and the rotor element mounting groove, described first compensating groove be communicated with described slide plate body on, following two ends chamber, be provided with second compensating groove between the described rolling seat, on the described seat that rolls of described second compensating groove connection, following two ends chamber is equipped with tourelle on the described rolling seat.
Further, described tourelle comprises bearing, little axle, and described bearing is fixed on the described rolling seat by little axle.
The utility model working principle: the driven by motor main shaft rotates around clockwise direction, and main shaft makes rotor element rotate around clockwise direction by key.Under action of centrifugal force, the hydraulic booster element will be thrown out of, and contact with stator component surface molded lines.In the rotary course of rotor element, along with the volume between rotor element and the stator component will constantly change, and the volume that changes has formed the pump cavity that the rotor pump fluid medium is carried out supercharging.Flowing medium enters pump cavity from stator component inlet, and the hydraulic booster element carries out supercharging with fluid medium, and the fluid after the supercharging is from the outlet port excavationg pump cavity of stator component, and this is a circulation.
When hydraulic booster element of the present utility model carried out supercharging to liquid, its front portion was a high-pressure medium, and the rear portion is low piezodielectric.The hydraulic booster element has been subjected to P
