Technical Field

The invention belongs to a new material, and particularly relates to a low-cost wear-resistant cylinder sleeve with stable quality and a process thereof.

Background

The high-pressure slurry pump is the heart of the petroleum drilling and geological exploration working platform, and the slurry pump cylinder sleeve is an important component of the slurry pump. The mud pump cylinder sleeve that uses at present divide into bimetal cylinder sleeve, pure alumina ceramics cylinder sleeve and three kinds of materials processing of pure zirconia ceramics cylinder sleeve and forms: because the working condition is very bad, the bimetallic cylinder sleeve is not wear-resistant, corrosion-resistant and scouring-resistant, and the service life is very short; the pure alumina ceramic cylinder sleeve has low strength and toughness and is easy to break under high pressure; the pure zirconia ceramic cylinder sleeve is easy to pulverize, low in heat conductivity coefficient, large in expansion coefficient, low in hardness, easy to damage a matched piston, high in processing cost, high in selling price, low in cost performance and incapable of achieving ideal effects.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the low-cost wear-resistant cylinder sleeve and the process thereof, wherein the low-cost wear-resistant cylinder sleeve is low in production cost, simple in processing method, reasonable in process, stable and reliable in product quality and wear-resistant.

The invention relates to a low-cost wear-resistant cylinder sleeve with stable quality, which comprises the following components in percentage by weight: the aluminum oxide powder is mainly used, the content is 50-99 wt%, and the content of the zirconium element ore powder, the magnesium element containing compound powder, the chromium element containing compound powder, the manganese element containing compound powder, the Suzhou soil powder and the barium element containing compound powder is respectively 0.1-10 wt%.

Wherein: the aluminum oxide is alumina powder, the mineral powder of zirconium element is zirconium silicate or zirconium oxide, the compound powder containing magnesium element is magnesium carbonate, magnesium oxide, magnesium nitrate or talcum powder, the compound powder containing chromium element is chromium oxide or chromium carbonate, the compound powder containing manganese element is manganese oxide or manganese carbonate, the Suzhou soil powder is mineral containing silicon element, and the compound powder containing barium element is barium oxide or barium carbonate.

The preparation process of the low-cost wear-resistant cylinder sleeve with stable quality comprises the following steps:

firstly, ball milling and spray drying raw materials weighed according to a formula to prepare granular powder;

secondly, the granular powder is made into a wear-resistant pipe through cold isostatic pressing (forming by adopting cold isostatic pressing equipment) and high-temperature sintering;

processing the excircle and the end face of the high-temperature sintered wear-resistant pipe, and placing the processed wear-resistant pipe into a fully expanded metal jacket;

and fourthly, performing coarse grinding and polishing on the inner circle of the wear-resistant pipe, thereby preparing the low-cost wear-resistant cylinder sleeve.

The preparation method is simple, the process is reasonable, the qualification rate of finished products is high, the production cost is greatly reduced, the prepared products are stable, reliable and wear-resistant in quality, and the service life of the products is greatly prolonged.
