往复式矿浆液压隔膜泵无泄漏隔膜的结构
Structure of non-leakage diaphragm of reciprocating hydraulic diaphragm pump for slurry transportation
摘要
Abstract
Conventional reciprocating hydraulic diaphragm pumps usually are with a single-layer dia-phragm structure to transport slurries.When the diaphragm ruptures,the leaked slurry can contaminate the hydraulic oil and subsequently damage to the hydraulic end components,eventually,increase the user maintenance costs.In order to eliminate this problem,a double-layer diaphragm structure without leakage is developed by studying the working principle of both the pump and the diaphragm and by analyzing the single-layer diaphragm structure,the rupture forms of diaphragm and the causes for rup-ture.Based on an analysis of design principle and working mechanism of the double-layer diaphragm, the pump with a double-layer diaphragm structure shows no difference in the performance from the pump with a single-layer diaphragm,and the drawback of the single-layer diaphragm is removed.A practical application proves that the double-layer diaphragm structure can completely meet the require-ments on design under actual working conditions.Thus,such a structure is greatly valuable to study on the reciprocating hydraulic diaphragm pumps for slurry transportation,and also of significance to ex-plore other similar diaphragm structures in a certain degree.关键词
