Sliding vane rotary-piston of the present invention has two kinds of purposes, and the first is as motor, namely when high-pressure liquid and low-pressure fluid exist simultaneously, promotes the piston rotation, and and then promote rotatingshaft and externally do work; It two is as pump, namely when there is rotating power source the outside, drives piston and rotates, and force low-pressure fluid to enter into hyperbaric chamber.These two kinds of usage piston basic structures are identical, but fluid inlet 7 is different with the position of fluid output 8, are used as the occasion of motor in the present invention, and fluid inlet 7 communicates with hyperbaric chamber 5, and fluid output 8 communicates with low-pressure cavity 6; Be used as the occasion of pump in the present invention, fluid inlet 7 communicates with low-pressure cavity 6, and fluid output 8 communicates with hyperbaric chamber 5, and with the exception of this, the structure of other parts is all identical.
Moving direction according to slide plate 2 relative rotors 1, the present invention is divided into radially two types of sliding vane rotary-pistons and axial sliding-vane type rotary-piston, illustrated in figures 1 and 2 be sliding vane rotary-piston basic structure schematic representation radially, and shown in Figure 3 be axial sliding-vane type rotary-piston basic structure schematic representation.
Fig. 1 is the cross sectional representation of sliding vane rotary-piston basic structure radially, when piston is used as motor, high-pressure liquid enters hyperbaric chamber 5 by fluid inlet 7, owing to have at least a slide plate to be positioned at piston region, and with hyperbaric chamber and low-pressure cavity isolation, there is pressure difference on the both sides of slide plate, high-pressure liquid will have active force to act on this slide plate this moment, slide plate is given rotor with force transmission, promotes the rotor rotation, and slide plate is also along with the rotor rotation, after this slide plate has rotated out piston region along with rotor, entered low-pressure cavity, the piston two sides no longer includes pressure difference, and moment no longer is provided, but because designing requirement constantly all has a slide plate at least in piston region for any one, therefore next slide plate one fixes in the piston region, and hyperbaric chamber and low-pressure cavity are isolated, and this slide plate then provides moment, thereby the moment that causes rotor to be continued, this process is carried out again and again, and rotor will continue to have moment loading, just can externally provide to rotatablely move.
The slide plate that enters low-pressure cavity slides along radial centripetal in this chamber, before entering the answer district, slide in the rotor, slide plate will be tried one's best in rotor and do not contacted to reduce friction with spacing block in replying the district, will be along radially centrifugal slip after the slide plate rotation enters hyperbaric chamber, before entering piston region, rotate to appointed positions in order to enter into piston region, the position of slide plate should be able to guarantee certain sealing effect to reach the requirement with high-pressure liquid and low-pressure fluid isolation in piston region, and the method that realizes this effect is structure such as the housing of slide plate and piston region wall, the front and back end socket, spacing block, rotors etc. keep in touch and do not stay excessive gap.The formula that endwisely slips rotary-piston is identical with the work course that radially slides the formula rotary-piston, different places be slide plate in low-pressure cavity along axial retraction, along axially skidding off, therefore rotor and other parts will carry out some corresponding structural adjustments at hyperbaric chamber.
When piston is used as pump, external power supply promotes the rotor rotation, and then promotion slide plate rotation, the direction of rotation should be to push low-pressure fluid to high-pressure liquid, slide plate before entering piston region owing to have at least a slide plate to be positioned at piston region, low-pressure fluid in the folded space of these two slide plates is just seized on both sides by the arms in the high-pressure spray tagma, and this process is carried out again and again, and low-pressure fluid will enter into hyperbaric chamber constantly.
In said process, the slide plate that enters hyperbaric chamber slides along radial centripetal in this chamber, before entering the answer district, slide in the rotor, slide plate will be tried one's best in rotor and do not contacted to reduce friction with spacing block in replying the district, will be along radially centrifugal slip after the slide plate rotation enters low-pressure cavity, rotate to appointed positions in order to enter into piston region before entering piston region, the position of slide plate should be able to guarantee that certain sealing effect is to reach the requirement with high-pressure liquid and low-pressure fluid isolation in piston region.The formula that endwisely slips rotary-piston is identical with the work course that radially slides the formula rotary-piston, different places be slide plate in low-pressure cavity along axial retraction, along axially skidding off, therefore rotor and other parts will carry out some corresponding structural adjustments at hyperbaric chamber.In the process that slide plate slides, the relative rotor of slide plate can be translation, and rotation to a certain degree also can be arranged.
No matter piston is used as motor still as pump, owing to require spacing block to have buffer action, high-pressure liquid can not enter into low-pressure fluid by this place.Therefore spacing block is a tabular or block structure, should be fixed on the housing, and perhaps simply be exactly a constituent element of housing, also contact with rotor or slide plate simultaneously, and should guarantee that spacing block and rotor or slide plate contact position have certain sealing effect.
Fluid inlet and fluid output can be arranged on the housing, also can be arranged on the end socket, perhaps one housing another on end socket, decide on user demand.Its fluid inlet of piston structure shown in Figure 2 and fluid output are all on housing, and its fluid inlet of piston structure shown in Figure 3 and fluid output are all on end socket.
The method of control slide plate arrival specified position has a variety of, and the most frequently used is at end socket or housing guide groove to be set, projection that cooperates with it of design on the slide plate, and this method is widely used in sliding-vane compressor, is technical mature methods.
The quantity of slide plate determines that method is as follows:
Centered by the axis of rotor rotation line, establish the angle that piston region opens and be
, owing to require to have a slide plate in any moment piston region at least, so the quantity of slide plate
Should satisfy
But consider that the sealing effect between common slide plate and housing, end socket and the rotor is not good; in order to improve sealing, be recommended in and will have guaranteed two slide plates in the piston region at least, this method can reduce the pressure difference of each slide plate both sides; reduce gas leakage/leakage speed, at this moment the quantity of slide plate
Should satisfy
To rotor require as follows:
Rotor should be solid of rotation, has groove on it, and the degree of depth of groove, length and width should be able to guarantee that slide plate can place wherein, and can guarantee that slide plate can be free to slide in the sliding area of design appointment.
To piston cavity require as follows:
The cavity of piston cavity for being surrounded by piston wall, piston wall is made up of one section stator wall and one section rotor outer wall, described stator wall refers to the surface of inner walls face, end socket internal face or spacing block, slide plate in piston cavity along with rotor moves perpendicular to piston wall, and should block the piston wall cross section, realize remaining the function that high-pressure liquid and low-pressure fluid are isolated.Piston cavity can be that transfiguration is long-pending, it also can be constant volume, the long-pending volume that refers to that two slide plates in the piston cavity surround of so-called transfiguration can change in rotation process, constant volume refers to that then the volume that two slide plates in the piston cavity surround can not change in rotation process, selecting variable volume still is that immutable volume needs to decide according to the demand of product.
In general, when piston axially can be very long the time, recommend to adopt radially sliding vane rotary-piston, when piston axially can not be oversize, or the housing radius recommends to adopt the axial sliding-vane type piston can be very big the time.
To motor, in a cycle of motion, the course that slide plate experiences is: reply district → hyperbaric chamber → piston cavity → low-pressure cavity → answer district; To pump, in a cycle of motion, the course that slide plate experiences is: reply district → low-pressure cavity → piston cavity → hyperbaric chamber → answer district, wherein slide plate only lives through a piston cavity, rotary piston with above-mentioned feature is called as the monocycle piston, if the course that the slide plate of rotary piston experiences is: reply district 1 → low (height) and press chamber 1 → piston cavity 1 → high (low) to press chamber 1 → answer district 2 → low (height) to press chamber 2 → piston cavity 2 → high (low) to press chamber 2 → answer district 1, be that slide plate can experience two piston cavity when rotating a circle, no matter how hyperbaric chamber and low-pressure cavity dispose, no matter be used as motor or as pump, all be called the binary cycle piston.Three cycles, the situation of multicycle piston such as phase piston all around can also be arranged equally, but generally speaking, monocycle piston and binary cycle piston are the most common situations.
The present invention and crank-connecting rod piston system have identical effect, and every crank-connecting rod piston system operable occasion the present invention all can use, but owing to eliminated the inertia loss from mechanism, its efficient will be higher than the crank-connecting rod piston system far away.The present invention can be used for turbomachineries such as automobile, generating, also can be used for the occasion of incompressible fluids such as hydroelectric power, hydraulic pump, has purposes very widely.
