Oil well pumps are downhole equipment for pumping oil. The liquid it sucks contains sand, wax, water, gas and corrosive substances, and it works underground at hundreds of meters to thousands of meters, and the internal pressure of the pump may be as high as 10 MPa or more. Therefore, its working environment is complex and the conditions are harsh, and the pump's working quality directly affects the output of the oil well. Therefore, the oil well pump should generally meet the following requirements:
(1) Simple structure, high strength, good quality, and reliable sealing of the connection part;
(2) The manufacturing material has good wear resistance and corrosion resistance, and has a long service life;
(3) The specifications and types can meet the needs of oil well drainage, and have strong adaptability;
(4) Easy to get up and down;
(5) Sand and gas control should be considered in the structure, and necessary auxiliary equipment should be provided.
