Description
Technical field
The present invention relates to a kind of displacement pump, particularly associated mode vane pump.
Background technology
Currently known traditional blades pump be by with suction, the pump housing of outlet, the rotor of biasing, multiple be inserted in rotor
Blade in radial slot and pump shaft composition, due to simple in construction, compact, suction capacity is strong, the steady no pulse of liquid stream, and efficiency is up to
More than 80%, it is used widely as oil pump.But traditional vane pump also has its defect, i.e. vane pump the most all can not
It is directly installed on motor, but is connect with motor by shaft coupling, and be installed along with on the pump seat of heaviness, but people expect
Vane pump is directly installed on motor, volume is little, lightweight associated mode vane pump, particularly can carry the straight of water
Connection formula vane pump, it can save shaft coupling and pump seat, substantially reduce the axial length of pump, save installing space, subtract again
Raw material and production cost are lacked.Additionally, traditional blades pump also has following two defect, one is outer face and the pump housing of blade
The two sides of inner surface and blade and left and right two static side plates all produce high-speed friction, cause heating, even make defeated
Medium is sent to produce vaporization；Two is the closing space surrounded by rotor outer circle, pump housing inner chamber and two blades, and its volume is in operating
During constantly produce change, when volume from large to small time, tired liquid situation easily occurs, due to liquid Incoercibility, unnecessary
Liquid from gap, be forced to extrusion, thus produce noise and vibration；Above-mentioned two critical defect not only makes the efficiency of pump bright
Aobvious decline, particularly blade rubbing heating, medium vaporizes, makes pump cisco unity malfunction.So, traditional blades pump can only be fitted reluctantly
For carrying the oil product that lubricity is good, and cannot be applicable to carry the water that lubricity is poor.
Summary of the invention
It is an object of the invention to: the shortcoming existed for above-mentioned vane pump, proposing one can be mounted directly vane pump
On the flange of motor, compact conformation is lightweight, blade will not produce and frictional heating, on-stream tired liquid will not occur
, can be not only used for conveying oil again can be used for carry water associated mode vane pump.
In order to achieve the above object, associated mode vane 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 vane pump 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 before pump chamber being divided into low-pressure area and the upper cut water 8 of higher-pressure region, lower cut water 9 and being fixedly mounted with both every
Plate 10 is formed with rear bulkhead 11, and described front dividing plate 10 and rear bulkhead 11 are equipped with coaxial with rotor 2 towards the inner side of rotor 2
Arc triangle constant breadth cam frid 12, described rotor assembly 7 is by rotor 2 and is packed in described rotor 2 both sides synchronous rotary
Two side plates 13 and the blade 3 that fits in rotor 2 radial slot of multiple cunning formed, the inner both sides of described blade 3 be shaped with
The rotating shaft 14 of axle, the rotating shaft 14 of the inner both sides of described blade 3 is respectively inserted in described front dividing plate 10 and the circular arc three on rear bulkhead 11
In the groove of limit shape constant breadth cam frid 12, the described pump housing 1 is directly packed on the flange of motor by motor link span 18, described
Pump shaft 4 and motor projecting shaft direct connection.
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.
Described upper cut water 8 and the two sides of lower cut water 9 in the technology of the present invention solution can be equipped with multiple small balls
17。
The present invention uses modularized design, and this modular construction 5 is made up of with rotor assembly 7 two large divisions pump chamber assembly 6.
Wherein pump chamber assembly 6 is the stationary part being arranged in the pump housing 1, and rotor assembly 7 is the machinery of pump.
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 high-speed friction；Additionally, two
Side plate 13 and rotor 2 are fixedly mounted with and are integrated and synchronous rotary, rotor 2 band moving vane 3 synchronous rotary again, therefore, two side plates 13 with
Blade 3 basic synchronization rotates, and only produces a small amount of relative displacement between two sides and the biside plate of blade 3, does not produce and rubs at a high speed
Wipe, so 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；
1. vane pump is directly installed on the flange of motor, and it can save shaft coupling and pump seat, substantially reduces pump
Axial length, saves installing space, decreases again raw material and production cost.
2. the present invention uses modular construction, uses the module of different in width can produce different grades of flow, one
Individual pump and fundamental mode can derive from the pump of multiple different flow.
3. according to displacement pump principle, the pressure of pump is unrelated with flow, but relevant to supporting power of motor, a stylobate type pump
It is equipped with the motor of different capacity, the series pump of different pressures can be formed.
4. blade 3 outer face and two sides are on-stream will not generate heat because of high-speed friction, will not make to be carried Jie
Matter vaporizes.
5. pump is on-stream does not produce because of liquid phenomenon, had both eliminated noise and vibration further improves efficiency, and
Operate steadily, service life long.
