Abstract
The utility model discloses an energy-saving plunger pump, relating to the structural improvement of a plunger pump. The utility model provides an energy-saving plunger pump, which can reduce the loadof the horsehead, and comprises a pump cylinder, wherein a plunger in the pump cylinder is connected with a sucker rod on the horsehead; check valves are respectively arranged at the bottoms of the pump cylinder and a plunger chamber; and an oil through hole is arranged at the upper part of the plunger chamber. The structural key points of the plunger pump lie in that the plunger consists of a lower plunger and an upper plunger; the outer diameter of the lower plunger is equal to the inner diameter of the pump cylinder; and the outer diameter of the upper plunger is equal to the inner diameter of a stop dog of the pump cylinder.
Description
Technical field:
The utility model relates to the improvement of plunger pump structure.
Background technique:
At present, in the oil recovery process of oil field, major part is to pump with pumping unit horsehead, drives oil well pump work under the deep-well by sucker rod, shaft bottom oil is taken out risen to ground.
Oil well pump adopts plunger pump usually under the deep-well, and plunger pump comprises the plunger in pump barrel and the pump barrel body, and the bottom in the bottom of pump barrel body and the plunger is respectively arranged with one-way valve; When the sucker rod drive lower plunger of horse head pulling is up, reduced the pressure of pump barrel, because the oil pressure effect in shaft bottom, OIH is opened the one-way valve of pump barrel body bottom, enters in the pump barrel body; Drive lower plunger when descending at the sucker rod of horse head pulling, pump barrel body internal pressure raises, and the one-way valve in the plunger is opened, the oil in the pump barrel enter the cavity of plunger by one-way valve and the oil pipe that links to each other with the cavity of plunger in; Motion rises to ground with shaft bottom oil so again and again.
Because the diameter of plunger upper-end surface is identical with pump barrel body internal diameter, plunger bears bigger pressure in up process, and just horse head bears bigger load, has wasted the energy.
The content of model utility:
The utility model is exactly at the problems referred to above, and a kind of energy-conservation plunger pump that reduces horse head load is provided.
For achieving the above object, the utility model adopts following technological scheme, the utility model comprises pump barrel, plunger in the pump barrel links to each other with the sucker rod on the horse head, the bottom of pump barrel, plunger cavity is respectively arranged with one-way valve, and the top of plunger cavity is provided with oil through, and its structure outline plunger is to be made of bottom plunger and top plunger two-part, the external diameter of bottom plunger is identical with the internal diameter of pump barrel, and the external diameter of top plunger is identical with the internal diameter of the block of pump barrel.
The beneficial effects of the utility model:
Plunger of the present utility model is in up process, because the block in the pump barrel blocks from the oil pressure in the oil pipe, the pressure that makes horse head bear is less, has reached good energy-conservation purpose.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises pump barrel 1, plunger 3 in the pump barrel 1 links to each other with the sucker rod on the horse head 9, the bottom of pump barrel 1, plunger cavity 4 is respectively arranged with one-way valve 2, one-way valve 10, the top of plunger cavity 4 is provided with oil through 6, plunger 3 is to be made of bottom plunger 11 and top plunger 12 two-part, the external diameter of bottom plunger 11 is identical with the internal diameter of pump barrel 1, and the external diameter of top plunger 12 is identical with the internal diameter of the block 7 of pump barrel 1.
Be provided with pressure-releasing cavity 5 between block 7 and the bottom plunger 11, the pump barrel 1 of pressure-releasing cavity 5 is provided with the oil through 8 that can communicate with pump barrel 1 outer oil jacket ring; So that the draining between pump barrel 1 and the bottom plunger 3 is discharged smoothly.
