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 relates to an oil transfer pump for an oil refinery. The oil transfer pump for the oil refinery comprises a pump body and an impeller arranged in the pump body. The impeller comprises an aluminum alloy impeller body and a zirconium carbide system ceramic material layer outside the impeller body; the components of aluminum alloy and copper alloy are simple so as to meet the strength requirement of the oil pump; surface treatment processes such as acid pickling and passivating are carried out on the aluminum alloy and the copper alloy with the components, so that the problems such as the occurrence of any surface black spot are solved, and the surface cleanliness is realized.

Description

technical field [0001] The invention relates to an oil delivery pump for an oil refinery, and belongs to the technical field of oil refinery 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-term oil delivery operatio...
