Description
Technical field
The utility model relates to a kind of pump, and a kind of positive displacement sliding vane pump of more specifically saying so belongs to the fluid varactor machine technical field.
Background technique
The positive displacement sliding vane pump of prior art, owing to there be the high speed rotating frottage of slide plate to the front and rear covers end face, cause the wear out failure of slide plate and front and rear covers, make axial clearance not reach requirement, in let out area and strengthen, more cause parts to repair difficulty, change frequent, cost up, problems such as the shortening in working life of pump.In order to address this problem, Chinese patent literature CN1563721A discloses a kind of interior enclosed sliding slab self suction pump, comprise pump case and the stator that is set in the pump case, rotor is housed in the stator prejudicially, have groove on the rotor, slide plate is housed in the groove, is installed with front screen and backboard respectively, one wear-resistant material layer is arranged at front screen and backboard inner side surface in the both ends of the surface of rotor.Because the setting of described front screen and backboard, make described slide plate not contact with front and rear covers, thereby avoided friction with front and rear covers, play certain sealing effect, but the present invention does not solve the compensation problem after slide plate is worn, and still exists sealing problem and leakage problem after promptly described slide plate and front screen and the backboard wearing and tearing.
The model utility content
For this reason, technical problem to be solved in the utility model is to propose after a kind of slide plate wearing and tearing still the positive displacement sliding vane pump that can closely contact with front cover and rear end cover.
For solving the problems of the technologies described above, positive displacement sliding vane pump of the present utility model, comprise by columnar stator and be arranged on the front cover at described stator two ends, the pump case that rear end cover constitutes, be arranged on the rotor in the stator prejudicially, have groove on the rotor, slide plate is housed in the groove, the two halves structure of described slide plate for separating along rotor axial, and described slide plate is subjected to a biasing force that makes described two halves structure towards front cover and rear end cover.
Between described two halves structure, be provided with a thrust spring that applies described biasing force.
Staggered form fit by intercoupling between the described two halves structure.
A kind of landslide that is used for above-mentioned positive displacement sliding vane pump, the two halves structure of described slide plate for separating along rotor axial, and described slide plate is subjected to a biasing force that makes described two halves structure towards front cover and rear end cover.
Between the two halves structure of described slide plate, be provided with a thrust spring that applies described biasing force.
Staggered form fit by intercoupling between the two halves structure of described slide plate.
Technique scheme of the present utility model compared with prior art has following advantage: by with described slide plate along rotor axial structure in two, and a mechanism that makes described two halves structure towards the generation biasing force of front cover and rear end cover is set between the two halves structure, even make described slide plate after wearing and tearing, because the existence of the mechanism of described generation biasing force and can keep lasting quality of fit with front cover and rear end cover, thereby improved sealing, avoided problems such as working life of leakage problem, part replacement problem, pump is short; The slide plate that is used for the positive displacement sliding vane pump of the present utility model, simple in structure, easy to process, good sealing effect is very suitable for promoting.
Description of drawings
In order to make content of the present utility model, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below by clearer understanding
Fig. 1 is the radial structure schematic representation of positive displacement sliding vane pump of the present utility model;
Fig. 2 is the axial arrangement schematic representation of positive displacement sliding vane pump of the present utility model;
Fig. 3 is a kind of schematic representation of mode of execution of the slide plate of positive displacement sliding vane pump of the present utility model;
Fig. 4 is the schematic representation of another mode of execution of the slide plate of positive displacement sliding vane pump of the present utility model.
Reference character is expressed as among the figure: 1-positive displacement sliding vane pump, 2-stator, 3-front cover, 4-rear end cover, 5-rotor, 6-slide plate, 7-suction port, 8-exhaust port, 9-thrust spring.
Embodiment
Fig. 1 and Fig. 2 are the structural representations of positive displacement sliding vane pump of the present utility model, comprise by columnar stator 2 and the front cover 3 that is arranged on described stator 2 two ends, the pump case that rear end cover 4 constitutes, be arranged on the rotor 5 in the stator 2 prejudicially, have groove on the rotor 5, slide plate 6 is housed in the groove, wherein, stator 2 is made of circle tube member and the suction port 7 and the exhaust port 8 that are molded on the circle tube member, the two halves structure of described slide plate 6 for axially separating along rotor 5, and described slide plate 6 is subjected to the biasing force of the described two halves structure of making of thrust spring 9 towards front cover 3 and rear end cover 4, staggered form fit by intercoupling between the described two halves structure is referring to Fig. 3 and Fig. 4.
In addition, in the structure of slide plate 6, what described two halves structure was applied biasing force not only can be that thrust spring 9 can also be other device, as utilizing magnetic pole of the same name to produce the device of repulsion or utilizing gum sleeve to produce the device etc. of elastic force.
The working procedure of positive displacement sliding vane pump 1 of the present utility model is as follows:
When eccentric rotor 5 presses that the direction of arrow is rotated among the figure in stator 2, drive slide plate 6 also along with rotor 5 rotates stator 2 in, because of stator 2 and rotor 5 have a throw of eccentric, so can form the sealed mode volume-variation.Under action of centrifugal force, several airtight swept volumes have been constituted between two adjacent slide plates 6 and stator 2 internal surfaces and rotor 5 outer surfaces, referring to Fig. 1, top slide plate 6 stretches out gradually, the work visitor that slide plate is 6 is long-pending to increase gradually, forms parital vacuum, and the fluid in the container is under the atmospheric pressure effect, enter the seal operation volume by suction port 7, finished the process that pump is inhaled fluid; Bottom slide plate 6 is pushed back in the groove gradually by stator 2 surfaces, and swept volume reduces gradually, discharges through exhaust port 8, has finished the process of pump current drainage body.
In the above-described embodiments, by with described slide plate 6 along rotor axial structure in two, and a mechanism that makes described two halves structure towards the generation biasing force of front cover and rear end cover is set between the two halves structure, even make described slide plate 6 after wearing and tearing, because the existence of the mechanism of described generation biasing force and can keep lasting quality of fit with front cover 3 and rear end cover 4, thereby improved sealing, avoided problems such as working life of leakage problem, part replacement problem, pump is short.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
