A spring is arranged in the groove. A slide plate is arranged in the slide sheet. A slide sleeve is arranged between the shell body and the slide plate. Both sides of the slide plate are protruded and sealed on both ends of the slide sleeve. The utility model has safe and convenient use, and small volume, overcomes the restraining force of the high viscosity of the thick liquid on slide sheets, causes the slide sheets to freely extend, and effectively improves the volumetric efficiency of the pump. The utility model has high work efficiency, long service life, good sealing performance and stable performance, and cost reduction.
Description
Technical field
The utility model relates to a kind of liquid pump, relates in particular to the high efficiency reciprocating rotor thick oil pump that the suction and the discharge of various media are finished in a kind of to-and-fro motion.
Background technique
The domestic and international at present reciprocating type rotor pump that in the conveying of high viscosity liquid, is adopted, JB/T8099-1999 type oil field rotor thick oil pump, its structure is: epitrochanterian slide plate is in the rotor rotation process, under action of centrifugal force, contact with inner surface of stator, cause wearing and tearing big, it is low that contact force reduces volumetric efficiency.The problem that JB/T8099-1999 type thick oil pump exists is that the life-span of pump is low, inefficiency, and volume is big, the cost of production height.
The model utility content
Technical problem to be solved in the utility model is in thick oil pump, and rotor and stator inner surface wearing and tearing are big, inefficiency, problems such as life-span weak point.
In order to solve the problems of the technologies described above, the utility model is achieved in that it comprises pump case, pump shaft, rotor and stator, its rotor and stator are eccentric structure, rotor is made up of synchronizing wheel and slide plate, and each slide plate two ends spindle nose is separately positioned in the chute of synchronizing wheel separately, and the working surface end of slide plate is provided with groove, be provided with spring in the groove, slide plate is arranged in the slide plate, is provided with sliding sleeve between pump case and the slide plate, and slide plate both sides projection is enclosed in the two ends of sliding sleeve.
The utility model uses safe ready, and volume is little, and it has overcome the restraining force of the high viscosity of thick liquid to slide plate, and slide plate is stretched out freely, has effectively improved the volumetric efficiency of pump; The spring structure that is provided with in the thick oil pump rotor of this kind structure and the eccentric structure of stator and the slide plate, the slide plate to-and-fro motion is not subjected to the influence of centrifugal force, makes the wearing and tearing of rotor and stator inner surface little, the working efficiency and the life-span of having improved pump; Sealing and stability are good; Volume is little, has reduced cost, is beneficial to enforcement.

Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1-8.The utility model comprises parts such as pump case 6, pump shaft 9, rotor, stator, end cap 11, pump cover 12.Wherein liquid sucting port 14 and liquid port 15 link to each other with separately pipeline respectively.Pump shaft is arranged in the eccentric pivot hole of end cap 11.Rotor is made up of synchronizing wheel 1 and slide plate 3, and synchronizing wheel 1 is hinged by the axle sleeve type sliding bearing with slide plate 3.Each slide plate 3 two ends spindle nose 7 is separately positioned in the chute 13 of synchronizing wheel 1 separately, and chute 13 is complementary with slide plate 3 two ends spindle noses 7, is 6.In rotation process, slide plate 3 to-and-fro motion by synchronizing wheel 1 effect, make slide plate 3 active forces even, generation can be good with absorption, the suction amount is big, defeated outward pressure height, and pulse is little, the lift height, and pulse and lift are irrelevant, and the rotor sliding-vane 3 of thick oil pump and stator inner surface wearing and tearing can be compensated automatically, increase the service life.The working surface end of slide plate 3 is provided with groove, is provided with spring 4 in the groove, improves the encapsulation of pump.Slide plate 2 is arranged in the slide plate 3.Be provided with sliding sleeve 5 between pump case 6 and the slide plate 2, slide plate 2 both sides projectioies are enclosed in the two ends of sliding sleeve 5, have improved the encapsulation of thick oil pump, have increased the wear resistance and the stability of thick oil pump.Be provided with thrust-bearing 10 between the end cap 11 of pump and the pump cover 12, reduce the pressure of axle, improved the stability of axle, increased the life-span of axle.The slide plate face of slide plate 2 can be the inclined-plane of 10 degree to 30 degree, and the best gradient of the slide plate face of slide plate 2 is 15 degree.Between synchronizing wheel 1 and pump shaft 9, be provided with equalizer bearing 8, improved the stability of thick oil pump.
When the rotor of high efficiency reciprocating rotor thick oil pump rotates under the driving of motor, because between rotor and stator is eccentric structure, rotor has adopted the spring automatic compensation structure of synchronizing wheel 1 structure and rotor, form the volume of sealing between rotor and stator, in rotation process, this volume changes from small to big, and more from large to small, thereby realizes imbibition and discharge opeing process.
