Abstract
The utility model relates to an enclosed volume displacement oil well pump. The centre of a cylindrical body of the utility model is provided with a swing axle; a medium outlet and a medium suction inlet are arranged on the upper and the lower positions of the cylindrical body; a lamellar bottom valve is arranged on the cylindrical body at the end part of the suction inlet; the inner ends of the suction inlet and the outlet are provided with one-way valves; a pair of a stationary blade and a moving blade which present a cross shape is arranged on the swinging axis; a cavity of the pump forms A, B, C, D chambers. The utility model has the advantages of simple structure, easy fabrication, reduced pump length, low cost, no idle running work, high pumping efficiency, minimum contact friction, slow abrasion and prolonged service life; the utility model is suitable for hydraulic oil production.
Description
The utility model relates to a kind of hydraulic oil producing that is applicable to and places the closed volume oil well pump of underground work.
Most mechanical type oil pumping technologies that adopt in the petroleum production process, various mechanical accidents that its equipment attrition causes or generation is often arranged with electrification have influenced oil recovery efficiency and have increased cost of production, thereby
Begin to develop hydraulic oil producing technology at present, but its original oil well pump can't be applicable to hydraulic oil producing.The purpose of this utility model is to provide a kind of and is applicable to hydraulic oil producing, places the closed volume oil well pump of underground work, has usefulness such as efficient height, little, the encapsulation of wearing and tearing are strong, long service life.
The purpose of this utility model is achieved in that a kind of closed volume oil well pump, have a cylindrical pump barrel body, it is characterized in that being provided with swing axis in the middle of the cylindrical shell, the upper and lower position of cylindrical shell is provided with medium exhaust port and suction port, the suction port end cylinder is provided with the sheet bottom valve, reach sealing process to pump chamber, make in the preceding pump chamber of start and do not advance impurity or oil, be provided with one-way valve at suction port and exhaust port the inner, medium is flowed by a direction, swing axis is provided with a pair of stator blade and moving vane is " ten " font, makes its pump chamber form four Room.Its working principle is: after it and oil hydraulic motor are assembled, and under oil hydraulic motor drives, the balance staff action that is connected with motor output shaft, moving vane moves with axle, when chamber is enlarged, the closed check valve on the exhaust port, the one-way valve on the suction port is opened, the suction medium; When chamber was dwindled, the closed check valve on the suction port and one-way valve on the exhaust port is opened was discharged medium, forms liquid stream one-way flow, compiles at the outlet end at last, finishes the drawing liquid process.
This model utility structure tube is single, easy to manufacture, cost is low, no idle running work, encapsulation strong, wearing and tearing are little, efficient is high, has use value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
As shown in Figure 1, a kind of closed volume oil well pump, have a cylindrical pump barrel body (1), be provided with swing axis (2) in the middle of its cylindrical shell (1), the upper and lower position of cylindrical shell is provided with medium exhaust port (9) and suction port (8), suction port (8) end cylinder is provided with sheet bottom valve (5), be provided with one-way valve (6,7) in suction port (8) and exhaust port (9) the inner, swing axis (2) is provided with a pair of stator blade (3) and is " ten " font with moving vane (4), and its pump chamber forms A, B, C, D four Room.
