Embodiment Construction

[0015] The oil well pump includes a pump cylinder and a plunger, ceramic coatings are respectively provided on the inner and outer walls of the pump cylinder, and ceramic coatings are respectively provided on the inner and outer walls of the plunger.

[0016] Since the inner and outer walls of the pump barrel are respectively provided with ceramic coatings, and the inner and outer walls of the plunger are respectively provided with ceramic coatings, and the ceramic coating is a very dense structure, so the high temperature corrosion resistance of the oil well pump is guaranteed. Strong, high friction and wear resistance, greatly extended service life.

[0017] In addition, the pump barrel and the plunger are all aluminum alloys (the reasons for choosing high-strength aluminum alloys are: 1. Aluminum alloys can be subjected to plasma electrolytic oxidation treatment, which is the best way to prepare dense Al alloys. 2 o 3 One of the necessary conditions for ceramic coating; 2....

Abstract

The invention discloses an oil well pump which comprises a pump cylinder and a plunger piston, wherein ceramic coatings are arranged on the inner wall and the outer wall of the pump cylinder respectively; and ceramic coatings are arranged on the inner wall and the outer wall of the plunger piston respectively. The ceramic coatings are arranged on the inner wall and the outer wall of the pump cylinder respectively, the ceramic coatings are arranged on the inner wall and the outer wall of the plunger piston respectively, and the ceramic coatings are in a very compact structure, so that high temperature resistance ability and high corrosion resistance ability of the oil well pump are guaranteed, the anti-friction ability and the wear resistance ability are high, and the service life is greatly prolonged. A manufacturing method of the oil well pump is also provided.

Description

technical field [0001] The invention belongs to the technical field of oil recovery in oil fields, and in particular relates to an oil well pump and a method for manufacturing the oil well pump. Background technique [0002] The oil well pump is one of the main equipment in the field of oil production in the oil field, so the service life of the oil well pump is directly related to the production efficiency and economic benefits of the oil field. Due to the specific working environment requirements of the oil production industry, the oil well pump has been exposed to high-temperature nitrogen and crude oil corrosion environment for a long time, and occasionally fine sand is mixed in when it is working, so that the plunger and pump barrel of the oil well pump are in a state of friction and wear for a long time . The effects of corrosion and friction and wear make the service life of the oil well pump low, and the scrapping of the oil well pump will cause great loss of oil pr...
