Novel oil well pump

Abstract

The invention relates to the technical field of oil well pumps, and discloses a novel oil well pump. The novel oil well pump comprises a base, through holes are formed in the left side of the base, nuts are movably installed on the left sides of the through holes, and a motor barrel is inserted into the right side of the base. According to the novel oil well pump, the nuts are arranged, the two through holes are formed in the left side of the base of the oil well pump and include the oil filling hole and the air discharging hole, the nuts are installed on the left sides of the through holes, sealing gaskets are fixedly installed at the joints of the through holes and the nuts, so that the sealing effect is better, meanwhile, sealing gaskets are fixedly installed at the joints between threaded pipes and the nuts, between the motor barrel and an oil cylinder, between the oil cylinder and a cylinder cover, between the cylinder cover and a pump cover and at the position, located at a coilhole, between the oil cylinder and the cylinder cover, the coil hole is transferred to the joint between the oil cylinder and the cylinder cover from the side wall of the motor barrel, so that the sealing performance of the joints of all the components of the oil well pump is improved, external gas is prevented from entering the oil well pump, or oil is prevented from leaking out, and the workingefficiency of the oil well pump is improved.

Description

technical field [0001] The invention relates to the technical field of oil well pumps, in particular to a novel oil well pump. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also be used to transport liquid and gas mixtures and liquids containing suspended solids. [0003] The oil well pumps currently on the market are mainly used in the production of chemical and petroleum sectors, but the traditional oil well pump wire outlet is on the side wall of the motor barrel, and the internal connection structure is not sealed by a sealing ring, the sealing effect is poor, and the number of fixed structures is insufficient. Oil well pumps are easy to freeze and burst in cold re...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of oil well pump, which has the advantages of good sealing effect and firm fixation, and solves the problem that the traditional oil well pump wire outlet is on the side wall of the motor barrel, and the internal connection structure has no sealing ring. , the sealing effect is poor, and at the same time, the number of fixed structures is insufficient. In cold areas, the oil well pump is easy to be frozen and burst.
