Problems solved by technology

In order to prolong the service life of the oil pump, the current solution is to lay segmented sintered ceramic sleeves on the inner wall of the oil pump barrel and the outer wall of the plunger. Although this improvement is excellent in wear resistance, high temperature resistance, and corrosion resistance , but the ceramic sleeve is prone to breakage, cracking and dislocation, and its impact resistance is low, which affects the performance of the oil delivery pump and is not conducive to long-term oil delivery operations.

Abstract

The invention provides an oil conveying pump which comprises a pump body and an impeller arranged in the pump body. The pump body comprises a copper alloy pump body, a titanium oxide system ceramic material layer on the outer surface of the pump body and a zirconium oxide system ceramic material layer on the inner surface of the pump body. The impeller comprises an aluminum alloy impeller body and a zirconium carbide system ceramic material layer outside the impeller body. Acid cleaning and passivating surface processing processes are conducted on aluminum alloy and copper alloy of the components, the problems of surface black points and the like are avoided, and the obtained surface is clean; the surfaces of the aluminum alloy and the copper alloy are coated with the ceramic materials, and the corrosion prevention, wear resistance and high-temperature resistance performance of the materials is improved.

Description

technical field [0001] The invention relates to an oil delivery pump, in particular to a pipeline oil delivery pump, and belongs to the technical field of oil delivery equipment manufacturing. Background technique [0002] The quality of the oil pump is becoming more and more important. The most vulnerable damages in use are corrosion, wear and sand jams. The service life of the oil delivery pump is getting shorter and shorter, and the cost of oil delivery is increasing year by year. In order to prolong the service life of the oil pump, the current solution is to lay segmented sintered ceramic sleeves on the inner wall of the oil pump barrel and the outer wall of the plunger. Although this improvement is excellent in wear resistance, high temperature resistance, and corrosion resistance , but the ceramic sleeve is prone to breakage, cracking and dislocation, and its impact resistance is low, which affects the performance of the oil delivery pump and is not conducive to long...
