Abstract
A blade type hand pump comprises a pump body, a rotor, blades and a pump shaft; a blade pump modular unit is mounted on an inner cavity of the pump body and comprises a pump chamber assembly and a rotor assembly; in the structure, arc-shaped trilateral equal-width cam groove plates are used as guiding mechanisms for the blades, the rotor and two side plates are connected into a whole to rotate synchronously, thus, during operation, heating caused by the fact that end surfaces of the blades rub against side surfaces can be avoided, vibration and noises produced by liquid trapping can be avoided, and the modular blade pump can be used for delivering oil and water. Compared with a traditional reciprocating manual pump, the blade type hand pump has the advantages that the blade type hand pump can save half the time when sucking same volume of water, a rotating handle better meets the operation habit of a person than an up-and-down swing arm, the person does not feel fatigue easily, all that is required for pump repair is to replace a module, the pump is convenient and rapid to repair, and the pump is high in self-priming performance, balanced in liquid flow and high in efficiency.
Description
Technical field
The present invention relates to a kind of displacement pump, particularly vane type hand pump.
Background technology
Currently known hand pump is swing arm piston reciprocating manual pump mostly, and this pump suction capacity is strong, simple in construction,
But shortcoming is suction one row, current are intermittent, and the cycle that discharges water is long.The vane pump belonging to displacement pump together also has good self-priming merit
Can, current are continuous, are highly suitable as hand pump, and it is by with suctions, the pump housing of outlet, the rotor of biasing, multiple slotting
Blade in rotor radial groove and pump shaft composition, due to simple in construction, compact, suction capacity is strong, the steady no pulse of liquid stream, effect
Rate is up to more than 80%, is used widely as oil pump.But traditional vane pump also has its defect, and one is the outer face of blade
All produce friction with the two sides of the inner surface of the pump housing and blade and left and right two static side plates, cause heating;Two be by
The closing space that rotor outer circle, pump housing inner chamber and two blades are surrounded, its volume constantly produces change in operation process, when
Volume from large to small time, tired liquid situation easily occurs, due to liquid Incoercibility, unnecessary liquid is forced to squeeze from gap
Go out, thus produce noise and vibration;Above-mentioned two defect makes the efficiency of pump decline, and may be only available for the oil product that lubricity is good,
And the water of poor lubricity cannot be applicable to, also uncomfortable as hand pump.
Summary of the invention
It is an object of the invention to: the shortcoming existed for above-mentioned swing arm piston reciprocating manual pump and vane pump, propose
A kind of compact conformation, current are coherent, blade will not abrasion, vibrations and the vane type hand pump of noise will not be produced.
In order to achieve the above object, vane type hand pump of the present invention, by the pump housing 1, the rotor 2 of biasing and the radial direction of rotor 2
The sliding blade 3 joined of groove and the pump shaft 4 bonded with described rotor 2 form, and it is characterized in that the described pump housing 1 inner chamber fills
Vane pump modular unit 5, described modular unit 5 is had to be made up of with rotor assembly 7 two large divisions pump chamber assembly 6, described pump
Chamber assembly 6 by pump chamber is divided into low-pressure area and the upper cut water 8 of higher-pressure region, lower cut water 9 and the front dividing plate 10 that is fixedly mounted with both with
Rear bulkhead 11 is formed, and described front dividing plate 10 and rear bulkhead 11 are equipped with the circular arc three coaxial with rotor 2 towards the inner side of rotor 2
Limit shape constant breadth cam frid 12, described rotor assembly 7 is by rotor 2 and is packed in two of described rotor 2 both sides synchronous rotary
The blade 3 that side plate 13 and multiple cunning fit in rotor 2 radial slot is formed, and the inner both sides of described blade 3 are shaped with coaxial turning
Axle 14, the rotating shaft 14 of the inner both sides of described blade 3 is respectively inserted in described front dividing plate 10 and the arc triangle etc. on rear bulkhead 11
In the groove of the frid 12 of wide cam frid 12.
The inner side of the described upper cut water 8 in the technology of the present invention solution can be shaped with the arc surface 15 coaxial with rotor 2,
The radius of described arc surface 15 can be equal with described blade 3 radius during overhang maximum from the radial slot of rotor 2, institute
The width stating cut water 8 can correspond to 60 ° of central angles in rotor 2 axle center.
The inner side of the described lower cut water 9 in the technology of the present invention solution can be shaped with rotor 2 with the arc surface of radius
16, the width of described lower cut water 9 can correspond to 60 ° of central angles in rotor 2 axle center.
The external part of the described pump shaft 4 in the technology of the present invention solution can be equipped with handle 20.
Vane type hand pump of the present invention uses modularized design, and this modular construction 5 is by pump chamber assembly 6 and rotor assembly 7
Two large divisions forms.Wherein pump chamber assembly 6 is the stationary part being arranged in the pump housing 1, and the operating portion that rotor assembly 7 is pump
Point.
The movement in the radial slot of rotor 2 of the said structure Leaf is the control by arc triangle constant breadth cam frid 12
System, the maximum overhang of blade is controlled, now outside blade by the arc surface that radius in arc triangle constant breadth cam groove is R2
It is accurate matched in clearance between the arc surface 15 of end face and upper cut water 8, between them, does not produce friction;Additionally, two side plates
13 are fixedly mounted with rotor 2 and to be integrated and synchronous rotary, rotor 2 band moving vane 3 synchronous rotary again, therefore, and two side plates 13 and blade 3
Basic synchronization rotates, and only produces a small amount of relative displacement, do not produce high-speed friction between two sides and the biside plate of blade 3, therefore
This also will not generate heat.
By rotor 2 external cylindrical surface, upper cut water 8 arc surface 15 and two blades between the closing space that surrounded of angle
In operation process, its volume will not change, and reason is the arc surface 15 of upper cut water 8 and rotor 2 external cylindrical surface is
Concentric circular, two interlobate angles are fixing, and during the rotation of therefore two blades, the size of closed volume is constant fixed number,
Tired liquid phenomenon will not occur.And this two arc surface is the most concentric in traditional blades pump, so when two blades rotate, its volume
Occur constantly to change, when volume from large to small time, necessarily lead to tired liquid phenomenon.
The positive effect of the present invention is;
Hand pump compact conformation the most of the present invention, water outlet link up no pulse, and the period ratio swing arm manual pump that discharges water shortens one times.
2. outer face and the two sides of blade 3 are on-stream less than rubbing, the most not producing because of liquid phenomenon, therefore, and hand fortune
Turn light.
3. modularized design, uses different module widths, can obtain different grades of flow, generalization degree, save
Production cost.
