Abstract
An annular vane pump is composed of a pump body, a stator, a spring, a rotor, an elastic floating body, vanes, a liquid suction port, a liquid pressing port and the like, wherein the liquid suction port and the liquid pressing port are arranged on the pump body; the rotor, the stator and the spring are arranged in the pump body; the vanes contact with the inner surface of the stator through elastic force of the spring; and the elastic floating body is installed on the rotor and can adjust the volume in a liquid cavity along with the change of revolving speed under the actions of centrifugal force and self elastic expansion to increase or decrease the discharge volume so as to compensate the discharge capacity change of the pump when the revolving speed changes. The vane pump is simple in structure, easy to produce, safe, reliable, and capable of adjusting the discharge capacity due to the change of the revolving speed and delivering liquids such as gas, water and oil.
Description
Technical field
The utility model relates to a kind of pump, particularly relates to a kind of ring-like vane pump.
Background technique
Vane pump is that the blade in the rotor contacts with pump case (track ring), with the liquid of suction by the pump of oil-feed side pressure to the oil extraction side.Vane pump is comprised of parts such as rotor, stator, blade, oil distribution casing and end caps.The internal surface of stator is cylindrical hole, exists off-centre between rotor and the stator.Blade can slide in the groove of rotor flexibly, centrifugal force when rotor rotates and passing under the effect of root of blade pressure oil, vane tip is adjacent on stator inner surface, so just formed the one by one active chamber of sealing between two adjacent blades, oil distribution casing, stator and rotor.When rotor rotated by counter clockwise direction, the blade on right side was protruding, and the pressurization working lumen volume increases gradually, produced vacuum, so by window on inlet port and the oil distribution casing oil is sucked.And the inward indentation of left side blade, the volume of Seal cage dwindles gradually, and the fluid in the Seal cage is forced out and outputs in the system through another window of oil distribution casing and force feed mouth and goes.This pump in rotor is goed around process, the oil suction force feed each once, therefore claim single-acting pump.Rotor is subject to hydraulic radial influence of unbalance power, therefore claim again the unbalanced pump, its bearing load is larger.The vane pump that uses at present is along with the rotating speed of motor increases, and the power-assisted pump delivery also will along with increase, affect the application of vane pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ring-like vane pump is provided.
Ring-like vane pump described in the utility model, vane pump is comprised of the pump housing, stator, spring, rotor, elastic floating body, blade, liquid sucting port, hydraulic fluid mouth etc., at the pump housing liquid sucting port and hydraulic fluid mouth are arranged, be provided with rotor, stator and spring in the pump housing, blade contacts with the elastic force of stator inner surface by spring.Elastic floating body is installed on the rotor, along with the variation elastic floating body of rotating speed can be adjusted at the volume that occupies in the sap cavity under the effect of centrifugal force and self elastic telescopic, increases or reduces lifting rate, pump delivery variation when changing in order to compensating rotational speed.
The utlity model has good beneficial effect, simple in structure, easily make, safe and reliable, can adjust because of rotation speed change pump delivery size.Can carry gas, water, wet goods liquid.
Description of drawings
Fig. 1 is ring-like vane pump structure diagram, among the figure:
1 pump case; 2 stators; 3 springs; 4 rotors; 5 elastic floating bodies; 6 blades; 7 liquid sucting ports; 8 hydraulic fluid mouths.
Embodiment
In conjunction with above-mentioned accompanying drawing the utility model is further described.
Ring-like vane pump described in the utility model, the pump housing is made of the pump housing 1, stator 2, spring 3, rotor 4, elastic floating body 5, blade 6, liquid sucting port 7, hydraulic fluid mouth 8 etc., at the pump housing 1 liquid sucting port 7 and hydraulic fluid mouth 8 are arranged, be provided with rotor 4, stator 2 and spring 3 in the pump housing 1, blade 6 contacts with the elastic force of stator 2 internal surfaces by spring 3.Elastic floating body 5 is installed on the rotor 4, along with the variation elastic floating body 5 of rotating speed can be adjusted at the volume that occupies in the sap cavity under centrifugal force and self flexible effect, increases or reduces lifting rate, pump delivery variation when changing in order to compensating rotational speed.
