Description
Technical field
This utility model relates to sliding-vane pump, a kind of sliding-vane pump with low speed adaptation ability.
Background technology
Pump is the energy conversion device of the pressure energy mechanical energy of prime mover being converted to liquid.Pump is mainly used to carry the liquid such as water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal, it is possible to conveying liquid, gas mixture and the liquid containing suspended solids.The classification of pump has multiple, and wherein, sliding-vane pump is a wide variety of class pump.
The operation principle of existing sliding-vane pump is, slide plate in rotor is fitted with the inwall of pump case under the influence of centrifugal force, during rotor rotates, volume between slide plate and pump housing endophragm the most constantly changes, and the change of slide plate and pump case volume will realize input and the discharge of liquid, the sliding-vane pump of this structure operationally, is fitted with pump case to make slide plate can produce sufficiently large centrifugal force, rotor must reach the highest rotating speed, and external motive device is also had higher requirement by this.
Utility model content
This utility model is intended to provide a kind of rotor that has only to have the relatively slow-speed of revolution and just can realize the low speed that has that sliding-vane pump normally works and adapt to the sliding-vane pump of ability.
The low speed that has in this programme adapts to the sliding-vane pump of ability, including pump case, pump case is provided with working chamber, working chamber be respectively provided on two sides with the inlet opening and liquid outlet communicated with working chamber, go back eccentric setting in working chamber and have rotor, rotor is connected with external motive device, rotor circumference is evenly equipped with at least four the first groove, it is provided with screw in first groove, screw is connected with rotor threads, the slide plate that can move back and forth it is additionally provided with along the first groove in first groove, the second groove is offered on slide plate, the head of screw stretches in the second groove, it is additionally provided with stage clip between screw and the second groove, stage clip one end offsets with the second groove, the stage clip other end offsets with the head of screw.
The principle of this programme is: rotor drives the slide plate in the first groove to rotate together under the effect of external motive device, slide plate remains the laminating with pump housing endophragm when rotating under the effect of centrifugal force and stage clip, thus between slide plate and pump housing endophragm, form some cavitys, owing to rotor is off being arranged in working chamber, therefore rotor is during rotating, the cavity of the slide plate and pump housing endophragm formation that are positioned at inlet opening side will be gradually increased and form low pressure chamber, in now liquid is inhaled into cavity, when rotor continues to rotate at liquid outlet, the cavity that slide plate is formed with pump housing endophragm is gradually increased and becomes high pressure chest, liquid after pressurized will flow out at liquid outlet, rotor ceaselessly rotates, thus realize liquid and ceaselessly suck and discharge, until the conveying of liquid completes.
The effect of this programme is: this programme sets up stage clip at slide plate, when rotor speed is the lowest, in the case of slide plate centrifugal force is the least, stage clip also can make the slide plate inwall all the time with pump case fit and form the cavity of closing, therefore the sliding-vane pump of this programme has only to rotor and has relatively low rotating speed and just can normally work, and sliding-vane pump is relatively low to the requirement of external motive device.
Further, rotor is attached by flat key with external motive device, the connected mode convenient disassembly of flat key and stable and reliable working performance.
Further, rotor circumference is evenly equipped with six the first grooves, and rotor rotates a circle and can realize suction and the discharge of six liquid, improves the work efficiency of sliding-vane pump, and the intensity of rotor self also can guarantee that.
Further, pump case being arranged with centered by working chamber two footing, footing is provided with installing hole, and pump case is fixed on external rack by the installing hole at two footing.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: pump case 1, inlet opening 2, working chamber 3, footing 4, liquid outlet 5, rotor 6, screw 7, slide plate 8, stage clip 9.
Embodiment is the most as shown in Figure 1: has low speed and adapts to the sliding-vane pump of ability, including pump case 1, the right side of pump case 1 is provided with inlet opening 2, the first inner stopper it is further opened with at inlet opening 2, the working chamber 3 of circle it is additionally provided with in the left side of inlet opening 2, the right side of working chamber 3 communicates with the left side of inlet opening 2, it is additionally provided with liquid outlet 5 in the left side of working chamber 3, the left side of working chamber 3 and the right side of liquid outlet 5 communicate, the second inner stopper it is further opened with at liquid outlet 5, pump case 1 carries out location fit by the first inner stopper and the second inner stopper with external pipe, centered by working chamber 3, two footing 4 also it are arranged with in the downside of pump case 1, installing hole is all offered on two footing 4, pump case 1 is fixed by two installing holes on footing 4.
In the working chamber 3 of pump case 1, eccentric setting has the rotor 6 of circle, the center of its rotor 6 is above working chamber 3 center, offering flat key groove on rotor 6, rotor 6 is attached by flat key with external device (ED), the connected mode convenient disassembly of flat key and stable and reliable working performance.
Circumference at rotor 6 is also evenly equipped with the first some grooves, in the present embodiment, the first groove is six that circumference is uniform, for convenience of description, illustrate as a example by the first groove that the present embodiment is located on the upside of round rotor 6 longitudinal axis, screw 7 it is provided with in the first groove, the downside of screw 7 is threaded togather with rotor 6, and the height that screw 7 occupies in the first groove is about 3/4ths of the first groove height.
It is additionally provided with slide plate 8 at the first groove, slide plate 8 can move back and forth along the first groove, the second groove is offered in the middle part of slide plate 8, the width of the second groove is as the criterion with the head that can place lower screw 7, it is additionally provided with flexible member between the second groove and screw 7, the present embodiment uses stage clip 9, the stable work in work of stage clip 9 and low cost, the upper end of stage clip 9 offsets with the second groove of slide plate 8, the lower end of slide plate 8 offsets with the head of screw 7, under the active force of stage clip 9, slide plate 8 can remain and the fitting tightly of pump case 1 inwall.
When rotor 6 turns clockwise under the drive of external motive device, the cavity formed between slide plate 8 and pump case 1 inwall at inlet opening 2 is gradually increased, outside liquid enters cavity, the cavity formed between slide plate 8 and pump case 1 inwall at liquid outlet 5 is gradually reduced, liquid flows out from liquid outlet 5, thus under rotor 6 ceaselessly rotates, it is achieved liquid do not stop suck and flow out.
