The stator is composed of the cylinder-shaped component, a liquid suction inlet and a liquid exhaust outlet which are shaped on the cylinder-shaped component; a rotor is eccentricly arranged in the stator and is provided with cutting grooves which is arranged with a sliding blade; An annular groove is provided on the both end surfaces of the stator and is presented in the shape of arc-shaped grooves between the cutting grooves, each arch-shaped groove is provided with a gland strip, and the ends of the gland strip can be hermetically and movably contacted with the sliding blade. In the sliding vane pump with the technical proposal, the rotor and the sliding blade cannot produce friction with the front and the rear covers of the sliding vane pump, therefore guaranteeing the seal inside the sliding vane pump, and greatly prolonging the service life of the sliding vane pump.
Description
Technical field
The utility model relates to a kind of sliding vane pump.Specifically a kind of sliding vane pump that is provided with Sealing.
Background technique
Originally just there is matching gap in the sliding vane pump of prior art when it is made, and its rotor and slide plate high speed rotating in the using process, produces very big friction with the inboard of the front and rear covers of sliding vane pump.This friction causes the wear out failure of parts such as rotor, slide plate and front and rear covers, can not guarantee that not only sliding vane pump seals all the time, and the frequently replacing of the parts of wearing and tearing, makes cost up, has shortened the working life of sliding vane pump.For solving the friction problem between the parts, Chinese patent literature CN1563721 proposes to be installed with front screen and backboard respectively in the both ends of the surface of rotor, and scribbles the high-abrasive material of a strata tetrafluoro class material membrane or chrome-plated metal layer at the inner side surface of front screen and backboard.But the high-abrasive material price of using in this repacking is very expensive, and cost has been improved greatly.
The model utility content
For this reason, technical problem to be solved in the utility model is to produce friction because of the front and rear covers of rotor, slide plate and sliding vane pump, and the component wear that causes causes sliding vane pump to lose the problem of sealing effect.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of sliding vane pump that is provided with Sealing comprises the pump case that is made of stator and the forward and backward lid that is arranged on the circle tube member two ends; Described stator is made of described circle tube member and the fluid intake and the fluid discharge outlet that are molded on the described circle tube member; Rotor is housed in the described stator prejudicially, on described rotor, offer grooving, be provided with slide plate in the described grooving, on two end faces of described rotor, have circular groove, described circular groove is shown as curve bath one by one between described grooving, be provided with Stamping Steel Ribbon in each described curve bath, the end of described Stamping Steel Ribbon is suitable for described slide plate sealing and contacts slidably.
Described Stamping Steel Ribbon is an elastic material, and described Stamping Steel Ribbon embeds in the described curve bath along described rotor axial direction compression ground.
Technique scheme of the present utility model has the following advantages compared to existing technology, adopted the sliding vane pump of technique scheme, rotor and slide plate do not produce friction with the front and rear covers of sliding vane pump, have guaranteed the sealing of sliding vane pump inside, and have promoted the working life of sliding vane pump significantly.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, 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
Fig. 1 is the sectional drawing of sliding vane pump of the present utility model;
Fig. 2 is the left sectional view of sliding vane pump of the present utility model.
Reference character is expressed as among the figure: 1-stator, 2-rotor, 3-slide plate, 4-curve bath, 5-rubber weather strip, 6-fluid intake, 7-fluid discharge outlet
Embodiment
To shown in Figure 2, sliding vane pump of the present utility model comprises the pump case that is made of stator 1 and the forward and backward lid that is arranged on the circle tube member two ends as Fig. 1; Described stator 1 is made of described circle tube member and the fluid intake 6 and the fluid discharge outlet 7 that are molded on the described circle tube member; The inside of described stator 1 is equipped with rotor 2 prejudicially, offers grooving on described rotor 2, is provided with slide plate 3 in the described grooving.On two end faces of described rotor 2, have circular groove, described circular groove is shown as curve bath 4 one by one between described grooving, in each described curve bath 4, be provided with rubber weather strip 5, described rubber weather strip 5 embeds in the described curve bath 4 along described rotor 2 axial directions compression ground, the end of described rubber weather strip 5 is suitable for described slide plate 3 sealings and contacts slidably, and described rubber weather strip 5 also seals and contacts slidably with the front and rear covers of sliding vane pump.When using sliding vane pump; described rotor 2 and described slide plate 3 be high speed rotating in described stator 1; owing to be provided with described rubber weather strip 5; described rotor 2 can directly not contact with the front and rear covers of described sliding vane pump with described slide plate 3; can not produce friction between them, therefore protect the parts such as front and rear covers of described rotor 2, described slide plate 3 and described sliding vane pump up hill and dale.The friction that the front and rear covers of described rubber weather strip 5 and described sliding vane pump produces, can make described rubber weather strip 5 wearing and tearing, but because described rubber weather strip 5 is to embed in the described curve bath 4 along described rotor 2 axial directions compression ground, because the restoration characteristics after elastic material is compressed, even, also can keep the sealing effect of sliding vane pump so described rubber weather strip 5 is worn away.
When sliding vane pump was worked, described rotor 2 of driven by motor and described slide plate 3 rotated in described stator 1, because described stator 1 and described rotor 2 have a throw of eccentric, so form the sealed mode volume-variation.Constituted the swept volume of several sealed between the internal surface of two adjacent described slide plates 3 and described stator 1 and the outer surface of described rotor 2.When described rotor 2 clockwise rotates, right half of slide plate 3 stretches out described grooving gradually, swept volume between the described slide plate also just increases gradually, form parital vacuum, liquid in the container or gas are under atmospheric effect, enter the seal operation volume by fluid intake 6, thereby finished the fluid suction process of pump; The half of slide plate 3 in a left side is pushed back in the described grooving by the internal surface of described stator 1 gradually, and described swept volume also reduces gradually, and liquid or gas are discharged through fluid discharge outlet 7, have finished the fluid discharge process of sliding vane pump.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to mode of execution.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 conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
