Background
The oil well pump is a device for assisting people in quickly taking petroleum, and along with the continuous development of science and technology, the requirements of people on the manufacturing process of the oil well pump are higher and higher; the existing oil well pump has certain defects when in use, the plunger and the pump barrel of the existing oil well pump are both metal surface coatings, the plunger and the pump barrel are in clearance fit, when crude oil contains sand, sand particles enter the fit clearance of the plunger and the pump barrel, phenomena such as eccentric wear, pump clamping and the like are easy to occur, efficiency is reduced or oil pumping equipment is in fault, certain adverse effects are brought to the use process of people, and therefore the anti-eccentric wear anti-clamping pump composite plunger oil well pump is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an anti-eccentric wear anti-sticking pump composite plunger oil-well pump can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an anti-eccentric wear anti-sticking pump compound plunger oil-well pump, includes the plunger, the outer wall of plunger is provided with the seal cover, the both ends surface of plunger all is provided with the jump ring, the surface of seal cover is provided with the pump barrel.
The sealing sleeve and the plunger are matched in a zero-clearance or interference fit manner, and the sand grains are organized to enter the matching surface of the pump barrel and the plunger, so that the phenomenon of eccentric wear and pump clamping is prevented.
Preferably, the outer surface of one side of the sealing sleeve is fixedly connected with the inner surface of the pump barrel through a clamping spring.
Preferably, a clamp spring groove is formed between the clamp spring and the plunger, and the outer surface of one side of the clamp spring is fixedly connected with the outer surface of one end of the plunger through the clamp spring groove.
Preferably, the number of the clamp springs and the number of the clamp spring grooves are two.
Preferably, the clamping spring is made of an anti-corrosion wear-resistant spring steel material.
Preferably, the sealing sleeve is made of wear-resistant and temperature-resistant plastic.
Compared with the prior art, the utility model discloses following beneficial effect has: this prevent eccentric wear and prevent compound plunger oil-well pump of sticking pump, become interference fit by traditional clearance fit, eliminate the clearance between plunger and the pump barrel, stop the sand grain and get into the pump barrel inner wall, prevent by the sticking pump, the output reduction or the equipment damage that wearing and tearing caused, be favorable to people to use, the metal friction between plunger and the pump barrel changes the friction between temperature resistant wear-resisting plastics and the metal into, the protection pump barrel inner wall is not destroyed, be favorable to people's use, whole oil-well pump simple structure, high durability and convenient operation, the effect of use is better for traditional mode.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-4, the eccentric wear and pump clamping prevention composite plunger oil well pump comprises a plunger 1, a sealing sleeve 3 is arranged on the outer wall of the plunger 1, clamp springs 2 are arranged on the outer surfaces of two ends of the plunger 1, and a pump barrel 4 is arranged on the outer surface of the sealing sleeve 3.
The outer surface of one side of the sealing sleeve 3 is fixedly connected with the inner surface of the pump barrel 4 through the clamp spring 2, so that the clamp spring 2 can be conveniently fixed; a clamp spring groove is formed between the clamp spring 2 and the plunger 1, and the outer surface of one side of the clamp spring 2 is fixedly connected with the outer surface of one end of the plunger 1 through the clamp spring groove, so that people can conveniently fix the plunger 1; the number of the clamp springs 2 and the number of the clamp spring grooves are two; the clamp spring 2 is made of an anti-corrosion and wear-resistant spring steel material, so that the service life of the clamp spring 2 can be prolonged; the material of the sealing sleeve 3 is wear-resistant temperature-resistant plastic.
It should be noted that, the utility model relates to an anti-eccentric wear anti-sticking pump composite plunger oil-well pump, when using, evenly process the jump ring groove on the oil-well pump plunger 1, jump ring 2 is anticorrosive wear-resisting spring steel material, the card is in the jump ring groove, seal cover 3 is wear-resisting temperature resistant plastics, seal cover 3 cooperates for zero clearance or interference fit with plunger 1, organize sand grain entering pump barrel 4 and plunger 1 fitting surface, prevent eccentric wear sticking pump phenomenon, become interference fit by traditional clearance fit, eliminate the clearance between plunger 1 and the pump barrel 4, stop sand grain entering pump barrel 4 inner wall, prevent by the sticking pump, the output reduction or the equipment damage that wearing and tearing caused, metal friction between plunger 1 and the pump barrel 4 changes the friction between temperature resistant wear resistant plastics and the metal into, protection pump barrel 4 inner wall is not destroyed, it is more practical.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
