5, can invert, it is achieved counter arrange well-flushing.
6, multistage slide block rotor pump unit can be multistage connected in series by keyway axis.
Accompanying drawing illustrates:
Fig. 1 is a kind of example structure schematic diagram of the present invention；
Fig. 2 is A-A structural representation as shown in Figure 1；
Fig. 3 is that B-B as shown in Figure 1 is to structural representation；
Fig. 4 is that C-C as shown in Figure 1 is to structural representation.
Detailed description of the invention:
Refering to Fig. 1-Fig. 4, a kind of down-hole oil production slide block rotor pump installation, including multistage slide block rotor pump unit and keyway axis 4.Multistage slide block rotor pump unit, including upper discharge sealing plate 1, negative camber body 2, lower suction seal plate 3, rotor block 5, slide block 6, pin 8 and pump case 9, linked together by keyway axis 4, and constrain in pump case 9, two ends are compressed by pump flooded suction 10 and discharge 11 respectively, lower suction seal plate 3 and negative camber body 2 are fixed with upper discharge sealing plate 1 by pin 8, form multistage slide block rotor pump unit, this multistage slide block rotor pump unit relies on slide block 6, form suction and seal interval, it was respectively provided with circulation groove 7 on upper discharge sealing plate 1 and lower suction seal plate 3, liquid is crossed in circulation groove 7 from this and is passed through, keyway axis 4 is linked together with rotor block 5 by long key, and drive it to rotate.Depending on multistage slide block rotor pump unit can be passed through keyway axis 4 1-200 connected in series level or need according to scene.
Slide block 6, at least provided with 3 pieces, represents 4 pieces in figure, and its one end is installed on the circumference of rotor block 5 in uniform way, and other end end face is arc surface structure, and this arc surface contacts with the face, interior garden of negative camber body 2.Circulation groove 7 of crossing on upper discharge sealing plate 1 is eccentric involute circle arc curve groove.Circulation groove 7 excessively on lower suction seal plate 3 is eccentric involute circle arc curve groove, and this curved groove is corresponding and in opposite direction with circulation groove 7 position excessively on upper discharge sealing plate 1.Rotor block 5 is installed with keyway axis 4 phase by long key.Keyway axis 4 is provided with long keyway, coordinates with the long key installed on rotor block 5 and installs mutually.
