Abstract
The invention discloses a sliding vane pump for conveying high-viscosity fluid. The sliding vane pump comprises a pump shell. A liquid inlet hole and a liquid outlet hole are formed in the two sides of the pump shell respectively. A rotor cavity is further formed between the liquid inlet hole and the liquid outlet hole. A rotor is arranged in the rotor cavity eccentrically. Six first grooves are evenly distributed in the circumferential direction of the rotor. A guide post and a sliding vane are arranged at each first groove. A gap is formed between each sliding vane and the corresponding first groove. A second groove is formed in each sliding vane. One side of each guide post is connected with the rotor, and the other side of each guide post stretches into the corresponding second groove. Each sliding vane can move along the corresponding guide post in a reciprocating mode. Compared with traditional sliding vane pumps, the sliding vane pump is advantageous in that since the first grooves have no guide function for the sliding vanes, the distances between the sliding vanes and the first grooves can be made large; in this way, even the high-viscosity fluid adheres to the sliding vanes, the sliding vanes still can work normally along the guide posts, accordingly, the sliding vane pump can effectively meet the requirement for conveying the high-viscosity fluid, and the application range of the sliding vane pump is widened.
Description
Technical field
The present invention relates to sliding vane pump, be specially a kind of sliding vane pump for high viscosity Liquid transfer.
Background technique
Pump is the energy conversion device of the pressure energy mechanical energy of prime mover being converted to liquid.Pump is mainly used to the liquid such as conveying water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal, also can conveying liquid, gas mixture and the liquid containing suspended solids.The classification of pump has multiple, and wherein, sliding vane pump is a class pump of extensive use.
The slide plate of sliding vane pump is generally placed in radial groove that rotor is opened, under the influence of centrifugal force, slide plate radially groove moves back and forth, when the sliding vane pump of this structure is when carrying some full-bodied liquid, slide plate inevitably adheres to some full-bodied liquid, because the movement of radial groove to slide plate has leading role, therefore only there is very little gap between radial groove and slide plate, therefore when slide plate being stained with full-bodied liquid, slide plate cannot be got back in radial groove again, this will cause sliding vane pump normally to work, so the sliding vane pump of planting structure cannot be used in some occasions needing to carry high viscosity liquid, the using scope of sliding vane pump will be restricted.
Summary of the invention
The invention is intended to provide one effectively can meet high viscosity Liquid transfer demand, effectively expand the sliding vane pump for high viscosity Liquid transfer of sliding vane pump using scope.
The sliding vane pump for high viscosity Liquid transfer in this programme, comprise pump case, pump case both sides offer inlet opening and liquid outlet opening respectively, also rotor chamber is provided with between inlet opening and liquid outlet opening, rotor chamber both sides communicate with inlet opening and liquid outlet opening respectively, in rotor chamber, eccentric setting has rotor, rotor is connected with external motor, periphery of rotor is evenly equipped with six the first grooves, first groove is provided with directional post and slide plate, between slide plate and the first groove, there is space, slide plate offers the second groove, the side of directional post is connected with rotor, the opposite side of directional post puts in the second groove, slide plate can move back and forth along directional post.
The principle of this programme is: under the drive of external motor, rotor drives slide plate High Rotation Speed, slide plate under the effect of self centrifugal force along directional post outwards movement, until the inwall of slide plate and pump case fits tightly, now six slide plates by between the inwall of pump case by formation six active chambers, because rotor eccentricity is arranged in rotor chamber, therefore in rotor rotation process, slide plate is when inlet opening, the active chamber that the inwall of slide plate and pump case is formed will increase gradually and form low-pressure cavity, now liquid is inhaled in active chamber, when slide plate is near liquid outlet opening place, the active chamber that the inwall of slide plate and pump case is formed will reduce gradually and form hyperbaric chamber, now liquid flows out from liquid outlet opening, rotor ceaselessly rotates, thus realize continuous suction and the outflow of liquid, complete the object of Liquid transfer.
The effect of this programme is: this programme arranges directional post in the first groove, slide plate moves back and forth along given route under the effect of directional post, this programme is compared with traditional sliding vane pump, because the first groove does not play the guiding role to slide plate, therefore the distance between slide plate and the first groove can do larger, even if therefore slide plate is stained with full-bodied liquid, slide plate still normally can work along directional post, therefore the sliding vane pump of this programme effectively can meet the delivery requirements of high viscosity liquid, expands the using scope of sliding vane pump.
Further, directional post comprises cylindrical section and thread section, and the thread section of directional post is connected with rotor threads, and directional post and rotor threads link together, the reliable performance be threaded and dismounting and easy for installation.
Further, inlet opening place offers the first inner stopper, and liquid outlet opening place offers the second inner stopper, and pump case to position with external pipe respectively by the first inner stopper of both sides and the second inner stopper and coordinates.
Further, pump case is arranged with centered by rotor chamber two and installs footing, install on footing and offer mounting hole, pump case is connected with external rack by the mounting hole installed on footing.
