Abstract
Owing to that in the circular arc recess of the end of the sliding vane contacting the surface of the inner diameter of the stator or outer diameter of the rotor, there is a sealing strip capable of floating around the center along with the variation of the angle contacting the surface of the inner diameter of the stator or outer diameter of the rotor, so that the contact of the sliding vane to the inner diameter of the stator or outer diameter of the rotor changes the line contact of the existent technology into surface contact, thus the contact strength is greatly decreased, the reliablity and life are increased. The invented penetrating double-vane composite sliding vane can also make the contour of the inner diameter of the stator of penetrating sliding vane pump or compressor changes from the curve shape into ordinary circular shape, thus the process for processing the inner diameter of the stator is simplified greatly.

The enforcement structural drawing that Fig. 2 and Fig. 3 look and overlook for the single slide plate (1A) in the penetration type biplate combination slide plate (1) or master (1B), dotted line is depicted as oilhole among the figure.
When Fig. 4 surpasses two for the quantity when penetration type biplate combination slide plate (1) in penetration type sliding vane pump or the compressor, middle single slide plate (1C) or enforcement structural drawing (1D).
Fig. 5 and Fig. 6 are that the master who is used for the one chip slide plate (3) of non-penetration type pump or compressor and rolling rotor-type pump or compressor looks and overlook the enforcement structural drawing, and (2) are the floating seal bar among the figure.
Purpose of the present invention illustrates it is to realize like this in conjunction with the embodiment of Fig. 7, Fig. 7 is a kind of enforcement structural drawing with penetration type sliding vane pump of two penetration type biplate combination slide plates (1), it is by stator (5), rotor (4), suction port (6) and exhaust port compositions such as (7), it is characterized in that: slide plate is penetration type biplate combination slide plate (1), single slide plate (1A) of its composition and (1B) and in the contacted end arc-shaped slot of stator (5), respectively there is its one side in groove, to swing, the floating seal bar (2) that another side then fits with the wall of stator (5) internal diameter.Its operating principle is: when rotor (4) drives penetration type biplate combination slide plate (1) in the groove and rotates in stator (5) under external force drives, since penetration type biplate combination slide plate (1) by single slide plate (1A) and (1B) and two floating seal bars (2) form, and single slide plate (1A) and (1B) it is laid floating seal bar (2) thickness and weight on one side and all is slightly larger than tail end, thereby under action of centrifugal force, make single slide plate (1A) and (1B) promote floating seal bar (2) and fit with stator (5) inner diameter wall.Simultaneously when rotor (4) is pressed among the figure direction of arrow rotation, the pressure that is transferred fluid acts on the tail end of the step of single slide plate (1A) and single slide plate (1B) simultaneously, thereby makes floating seal bar (2) more tight with contacting of stator (5) inner diameter wall.In order not cause the pressure that is transferred fluid excessive with the specific pressure of stator (5) inner diameter wall to floating seal bar (2), single slide plate (1A) and (1B) thickness of tail end change to be thinned to and make the specific pressure of floating seal bar (2) and stator (5) inner diameter wall reach appropriate thickness, make it to become stepped shaft.Because rotor (4) is eccentric in the internal diameter of stator (5), so the floating seal bar (2) in penetration type biplate combination slide plate (1) groove and the wrapping angle of stator (5) inner diameter wall, whenever revolve have in going around twice ascending, descending circuit simultaneously, floating seal bar (2) is swung in the groove of penetration type biplate combination slide plate (1), thereby guaranteed to contact with the reliable face of stator (5) inner diameter wall.
Since penetration type biplate combination slide plate (1) by two single slide plates (1A) and (1B) and two floating seal bars (2) form, and except that whole slide plate can move in the groove of rotor (4), two single slide plates (1A) and (1B) also can and be transferred under the effect of hydrodynamic pressure and relatively move at centrifugal force, therefore adopt penetration type pump or its stator of compressor (5) internal diameter of slide plate design of the present invention to can be plain cylindrical form, and needn't make the equidistant curve shape of rotor (4) rotating center, thereby design and manufacturing process have been simplified significantly, change by changing simultaneously, the penetration type sliding vane pump that the throw of eccentric of stator is made adjustable flow becomes possibility, and also simplified maintaining, improved operational safety and service life.
Fig. 8 is a kind of enforcement structural drawing of penetration type sliding vane pump of can regulate output flow, it is by stator (5), inner stator (10), rotor (4), adjusting screw rod (12), nut (11), spring (8), spring seat (9), suction port (6) and exhaust port compositions such as (7), it is characterized in that penetration type slide plate (1) is the biplate combined type, at penetration type biplate combination slide plate (1) and the contacted end of inner stator (10) inner diameter wall, a floating seal bar (2) is respectively arranged, its inner stator (10) can move radially at the internal diameter of stator (5) by the adjusting to adjusting screw rod (12), thereby reach by changing relative eccentricity, the purpose that realizes regulating output flow to rotor (4).
Fig. 9 obtains the enforcement structural drawing of the penetration type sliding vane pump of balance for adopting penetration type biplate combination slide plate (1) and radial force.It is characterized in that in stator (5), having the inner stator (10) of an oval internal diameter, cross next side that goes up of rotor (4) center line at inner stator (10) internal diameter minor axis, respectively there is an energy under the output fluid pressure effect, to keep the auxiliary slide plate (13) of a stepped shaft that contacts with stator (4) external diameter symmetrically, in the step gap of auxiliary slide plate (13), there is an aperture (15) to communicate with exhaust port (7), make it under the effect of discharging hydrodynamic pressure, produce the pressure that a maintenance contacts with rotor (4) external diameter appropriateness, therefore favourable minimizing pump in let out, improve volumetric efficiency.Also have an aperture (14) to communicate with pump intake (6) in the top clearance of auxiliary slide plate (13), the fluid that leaks in order to release reduces back pressure.Because four penetration type biplate combination slide plates (1) are arranged in the rotor (4), and a suction port (6) and an exhaust port (7) are respectively arranged on the both sides of rotor (4) symmetry, therefore the on-stream fluid that makes obtains balance to the radial force of rotor (4), and its working principle is described identical with Fig. 1.
Figure 10 makes up the enforcement structural drawing of the penetration type slide vane compressor of slide plate (1) for adopting the penetration type biplate, its working principle is when rotor (4) rotates under external force drives, under the effect of penetration type biplate combination slide plate (1), working fluid is pressed among the figure direction of arrow and is flowed, in order to reduce the radial leakage in the fluid compression procedure, set up an auxiliary slide plate (16) on the top of stator (5), in the step gap of auxiliary slide plate (16), there is an aperture (15) to communicate with relief opening, utilize the pressure of discharging fluid to make auxiliary slide plate (16) keep contacting with the appropriateness of rotor (4) external diameter, in order to reduce the pressure of leak fluid to auxiliary slide plate (16) top, in the gap at its top, also there is an aperture (14) to communicate, to reduce its back pressure with the suction port of stator (5).
Figure 11 is used for the enforcement structural drawing of rolling rotor-type pump or compressor for one chip slide plate (3).It is made up of stator (27), spring (24), one chip slide plate (3), rotor outer ring (22), rolling bearing (21), eccentric rotor (26) etc., it is characterized in that: the one chip slide plate (3) that is placed in stator (27) top has an arc-shaped slot with rotor outer ring (22) the contacted end of external diameter, there are its one side and the circular arc of groove to match the floating seal bar (2) that the external diameter of another side and rotor outer ring (22) fits in the groove; The ring elastic ring (23) that between rotor outer ring (22) and rolling bearing (21), also has materials such as an open circles annular that is made of metal or polyurethane elastomer or rubber or polythene, polyvinyl chloride, nylon, fluoroplastic to make.Because added this elastic ring (23) thus can guarantee on the one hand reliable contact of rotor outer ring (22) and stator (5) inner diameter wall, the machining accuracy and the matching requirements of reduction eccentric rotor (26) that on the other hand can be bigger and stator (5) internal diameter size, thus help reducing manufacture cost.Here for the reliable contact of bonding chip slide plate (3) to rotor outer ring (22), but do not cause its contact force excessive, the thickness of one chip slide plate (3) is made stepped shaft, on one side of its step towards the exhaust port that extrudes fluid, the pressure of fluid is added on the step, thereby guaranteed the contact pressure of one chip slide plate (3) to rotor outer ring (22) external diameter, in order to make pump or compressor bonding chip slide plate (3) when starting also have a spring (24) at the top of one chip slide plate (3) to the reliable contact of rotor outer ring (22).The working principle of rolling rotor-type pump of the present invention or compressor is: when eccentric rotor (26) is pressed among the figure direction of arrow rotation, drive rolling bearing (21), roll along stator (27) inner diameter wall in elastic ring (23) and rotor outer ring (22), fluid is inhaled into by the direction of arrow the figure from import, when the off-centre of eccentric rotor (26) forwards top dead center to, one chip slide plate (3) all is pressed in the stator (27), at this moment the volume maximum that is inhaled into of fluid, volume progressively dwindles when being rotated further, at this moment because the iris action of one chip slide plate (3), force fluid under the moment effect of eccentric rotor (26), the elastic resistance footpath exhaust port that overcomes reed valve plate (25) is discharged.Because the end that one chip slide plate (3) contacts with rotor outer ring (22) external diameter among the present invention, a floating seal bar (2) is arranged, and this root floating seal bar (2) can be along with the axle center along self swings in the groove of one chip slide plate (3) with the variation of rotor outer ring (22) external diameter contact angle, thereby make the contact that becomes face that contacts of one chip slide plate (3) and rotor outer ring (22) external diameter, therefore contact stress is reduced greatly, and also help the formation of lubricant film, this can improve the operational safety and the running life of this class pump or compressor greatly.
