In said mechanism, because stator has only an import and an outlet, rotor radial is subjected to force unbalance, and radial force is big, and pump shaft has amount of deflection, has had a strong impact on the working life of bearing and sealing.Particularly importantly, in the running of pump, slide plate directly contacts with stator inner surface all the time and makes sliding movement, easy to wear between slide plate and the stator, heating, not only influence reliability of products, and make the vaporizing liquid of conveying, cause the sliding vane pump working efficiency sharply to descend; Also cavitation phenomenons be may produce simultaneously, the normal operation and the work of pump seriously hindered.
(3) summary of the invention
Directly contact between the slide plate and stator inner surface in order to overcome in the prior art, the deficiency that cause serious wear, heating value is big, efficient is low, working life is short, the utility model provides a kind of slide plate not contact all the time with stator, and nothing is worn and torn, heating value is low, efficient is high, the double-action connectless sliding vane pump of long service life.
The technical solution of the utility model is:
A kind of double-action connectless sliding vane pump, comprise motor, coupling, pump housing assembly, described pump housing assembly comprises stifle, pump cover, pump closure, the pump housing, stator, slide plate, rotor, pump shaft, the saturating lid that connects successively, roller assembly, the axle of motor is connected by coupling with pump shaft, slide plate places in the radial groove of rotor slidably, roller assembly is installed at the slide plate two ends, pump closure is equipped with in the pump cover inboard, described roller assembly frame is on the pump closure internal surface, and described pump closure internal surface has and the same or analogous molded lines of the cross section of described stator interior.
Further, the curve of the cross section of described stator interior is by the orthodrome of radiuses such as two sections little circular arcs that wait radiuses, two sections, and four sections formed with the slick and sly excessive function curve of big or small circular arc, every section corresponding suction port of function curve or an exhaust port, described exhaust port is two outlets of radial symmetric.
Further, have uniform compensating groove on the slide plate, described compensating groove connects slide plate top and root, and the compensating groove opening direction is consistent with the sense of rotation of rotor.
The beneficial effect of double-action connectless sliding vane pump described in the utility model mainly shows: 1, utilize the roller assembly that is installed on the pump closure to control the movement locus of slide plate, guaranteeing that the slide plate top does not have directly with stator inner surface contacts, eliminated wearing and tearing and heating between slide plate and the stator, made efficient height, the good reliability of sliding vane pump; 2, the curve symmetry of the cross section of stator interior, be provided with two exhaust ports of two suction ports, described exhaust port is two outlets of radial symmetric, makes the balanced radial force of rotor, reduced noise and vibration in the pump operation process, the flow of sliding vane pump doubles simultaneously; 3, have uniform compensating groove on the slide plate, make to import and export the fluid pressure balance that the hydraulic coupling that acts on the slide plate top and rotor and cavity volume that slide plate surrounds act on the slide plate root, reduced the radial force of slide plate.

(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to accompanying drawing: a kind of double-action connectless sliding vane pump, comprise motor, coupling, pump housing assembly, described pump housing assembly comprises the stifle 1 that connects successively, pump cover 2, pump closure 3, the pump housing 4, stator 5, slide plate 6, rotor 7, pump shaft 8, saturating lid 9, roller assembly 11, the axle of motor is connected by coupling with pump shaft 8, slide plate 6 places in the radial groove of rotor 7 slidably, roller assembly 11 is installed at slide plate 6 two ends, pump closure 3 is equipped with in pump cover 2 inboards, 11 of described roller assemblies are on pump closure 3 internal surfaces 10, and described pump closure 3 internal surfaces have and the same or analogous molded lines of the cross section of described stator interior.Described stator interior is a stator inner surface.
The curve of the cross section of described stator interior is by the orthodrome of radiuses such as two sections little circular arcs that wait radiuses, two sections, and four sections formed with the slick and sly excessive function curve of big or small circular arc, every section corresponding suction port 13 of function curve or an exhaust port, described exhaust port are two outlets 14 of radial symmetric.
Have uniform compensating groove 12 on the slide plate 6, described compensating groove connects slide plate top and root, and the compensating groove opening direction is consistent with the sense of rotation of rotor 7.
During work, when slide plate 6 with before stator 5 internal surfaces contact, place the roller assembly 11 at slide plate 6 two ends to contact with the internal surface of pump closure 3.Because pump closure 3 internal surfaces have and the same or analogous molded lines of the cross section of described stator interior; roller assembly 11 is done rolling motion along pump closure 3 inner molded lines; controlling the motion of slide plate 6 simultaneously at stator 5 internal surfaces; guarantee to keep between slide plate 6 and stator 5 internal surfaces very little gap; go into very thin liquid film, this layer liquid film has the function of good heat conduction and bearing part residual solution pressure.
The pump closure 3 of slide plate 6, stator 5 internal surfaces and both sides forms a gap sealed cavity volume, rotation along with rotor 7, volume increases gradually from zero, continue rotation, volume reaches maximum value, when slide plate 6 forwarded the another one function curve to along with roller assembly 11, volume reduced gradually, and liquid is discharged from; When rotor 7 continued rotation, volume increased to maximum value again gradually, reduced to zero subsequently again.So in the utility model, rotor 7 whenever rotates a circle, therefore the volume periodically-varied twice in the cavity volume has reached the effect of double sucking double-row.
The purpose of compensating groove is in order to make the suffered residual solution pressure of slide plate 6 and rotor 7 reduce, no matter slide plate 6 is in suction area or discharge zone, all can flow into the cavity volume the inside that slide plate 6 roots and rotor 7 grooves are surrounded with the contacted liquid in slide plate 6 tops, make the hydraulic coupling that acts on slide plate 6 tops and root offset by compensating groove.And the sense of rotation of compensating groove opening direction and rotor 7 is consistent, and like this, the liquid that just slide plate 6 roots and rotor 7 grooves are formed in the cavity volume during slide plate 6 moving up and down in rotor 7 troughs becomes dead volume.
