Description
Technical field
The present invention relates to positive displacement pump technical field, feature is that low friction, bottom noise, structure be simple, efficient.
Background technique
Positive displacement pump causes swept volume periodically to increase and reduce and suction medium by the movement of workpiece, and leans on
The folding of workpiece squeezes and directly can increase the pressure of medium.Different according to moving component motion mode are divided into again:
Two class of reciprocating pump and drum pump.Performance parameter mainly has flow and lift, and in addition there are more than shaft power, revolving speed and required cavitation
Amount;Flow refers to the amount of liquid exported in the unit time by pump discharge, generally uses volume flow;Lift is that Unit Weight is defeated
Energy increment of the liquor charging body from pump intake to outlet, for positive displacement pump, energy increment is mainly reflected in pressure and can increase,
So usually replacing lift to indicate with pressure increment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low friction occlusion pump, half round rotor of 4- and 3- folding work
Arm is combined into the swept volume body of a similar eccentric circular, by eccentric shaft mode continuous rotation, drives similar disk
Volume done in cylinder body folding roll compression, thus cause 1- drive end bearing bracket swept volume periodically to increase and reduce and
Suction medium, and squeezed by the folding of workpiece and directly can increase the pressure of medium.

Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
Since during whole service, device and device are mainly mutually rolled, without direct friction, to drop significantly
Low friction ratio, increases the operational effectiveness of product.
Folding work arm is in entire operation, and since geometrical relationship generates the effect of regulations and parameters power, pressurization is situated between in by compression
In matter, further increase compression ratio.
Wherein improve the mode of pump output ripple and increase the method for flow, goes out the rolling of N group low friction in axis direction array
Pump, main component: 1- drive end bearing bracket；2- eccentric shaft；3- folding work arm；Half round rotor of 4-；5- rear end cap；6- enters check valve；7-
Check valve out；8- fore bearing gasket；9- fore bearing；10- rear bearing；11- rear bearing gasket；The example as cited by Fig. 3.
2- bias shaft design, each unit design angle are that 360/ array goes out N group number=eccentric shaft drive shaft angle；
Angle design after the array of 2- eccentric shaft, the exemplary diagram by taking 1 to 4 2- eccentric shaft combines as an example；The example as cited by Fig. 5.
3- folding work arm, length are to be less than 1- drive end bearing bracket inside diameter greater than 4- semicircle root diameter；With 1- drive end bearing bracket
The tangent side diameter of inside diameter is equal to 1- drive end bearing bracket inside diameter；Cooperate oil-free axis at the inner circle cooperation of axis outer circle and drive end bearing bracket
Close connection is held, there is stronger leakproofness.
3- folding work arm and the half round rotor joint 4- cooperation oilless bearing closely connect, and temperature becomes after long-play
Height has the generation of excessively cooperation phenomenon, there is stronger leakproofness.
