Description
Technical field：
The present invention relates to a kind of Hydraulic Field, specifically a kind of variable vane pump.
Background technology：
Hydraulic pump is the energy conversion device for converting mechanical energy into hydraulic energy, in hydraulic system, hydraulic pump as power source,
Pressure oil is provided to hydraulic system, the species of hydraulic pump is a lot, and single acting vane pump is exactly one of which, is used for variable pump,
Variable vane pump is to realize the work of oil suction and force feed by the closed working chamber volume change formed between blade, stator and rotor
Make pump, according to each seal operation volume rotor rotate a circle suction, force feed number determine, variable vane pump is complicated at present,
Blade is easily stuck, and use is not steady enough, and manufacturing cost is high.
The content of the invention：
The invention aims to overcome the shortcomings of the above, there is provided it is a kind of it is simple in construction, manufacturing cost is low, using it is steady, prolong
The variable vane pump of linear leaf service life.
The purpose of the present invention is achieved through the following technical solutions：A kind of variable vane pump, including the pump housing, pump body
The rotor and oil distribution casing of stator, stator interior, rotor deviate stator center and set, and are respectively press oil port and suction on the outside of pump housing both ends
Hydraulic fluid port, press oil port and the junction of inlet port and the pump housing are horn mouth, by rotating axis connection, stator between oil distribution casing and rotor
Inwall be provided with a circle wearing layer, rotor is provided with multiple blades, and blade is uniformly distributed using stator as the center of circle is contour in a ring.
The present invention further improvement is that：Blade is 6 or 8.
The present invention further improvement is that：Each blade is stainless steel, and each vane thickness is 3.5cm.
The present invention has advantages below compared with prior art：Rotor is provided with stator, is provided with rotor multiple
Blade, when the rotor is turning, due to the effect of centrifugal force, stator, rotor, blade and the oil distribution casing of both sides form several sealings
Working space, when rotor rotate, interlobate working space gradually increases, by inlet port oil suction, interlobate working space
Reducing, fluid extrudes from press oil port, and blade is stainless steel, and each vane thickness is 3.5cm, and blade is not easy to be stuck,
Extend the service life of blade, the present invention is simple in construction, manufacturing cost is low, using it is steady, extend blade service life, while loudspeaker
The setting of mouth is played a part of increasing fluid oil mass.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Label in figure：The 1- pump housings, 2- stators, 3- rotors, 4- oil distribution casings, 5- press oil ports, 6- inlet ports, 7- wearing layers, 8-
Blade, 9- rotary shafts, 10- horn mouths.
Embodiment：
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, the implementation
Example is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As Fig. 1 show stator 2 inside a kind of embodiment of variable vane pump of the present invention, including the pump housing 1, the pump housing 1,
Rotor 3 and oil distribution casing 4 inside stator 2, the deviation stator 2 of rotor 3 is centrally disposed, is respectively the He of press oil port 5 on the outside of the both ends of the pump housing 1
Inlet port 6, press oil port 5 and the junction of inlet port 6 and the pump housing 1 are horn mouth 10, and increase fluid is played in the setting of horn mouth 10
The effect of flow, connected between oil distribution casing 4 and rotor 3 by rotary shaft 6, the inwall of stator 2 is provided with a circle wearing layer 7, rotor 3
6 or 8 blades 8 are provided with, blade 8 is uniformly distributed with stator 2 for the center of circle is contour in a ring, and each blade 8 is stainless steel
Matter, each thickness of blade 8 are 3.5cm.
Rotor 3 is provided with stator 2, multiple blades 8 are provided with rotor 3, when rotor 3 rotates, due to centrifugal force
Effect, stator 2, rotor 3, blade 8 and the oil distribution casing 4 of both sides form the working space of several sealings, when rotor 3 rotates
Side, the working space between blade 8 gradually increase, by the oil suction of inlet port 6, when rotor 3 goes to opposite side, and the work between blade 8
Reduced space, fluid extrude from press oil port 5, and blade 8 is stainless steel, and each thickness of blade 8 is 3.5cm, and blade 8 is not easy
Be stuck, extend the service life of blade 8, the present invention have simple in construction, manufacturing cost is low, using it is steady, extend blade and make
The advantages of with the life-span.
