液压柱塞泵精密件失效原因分析及维护
|
摘要
液压柱塞泵是在液压系统压力油源核心部件,它的性能好坏直接影响到整个液压系统效率高低甚至能否连续正常工作。从液压轴向柱塞泵内部精密件结构特点和3对摩擦副工作机理,分析说明柱塞泵精密件基本磨损失效形式;同时,从使用过程中常见作业方法不当引起精密件失效原因共同分析,并说明相应使用维护正确方法。目的是通过了解其失效原理后,可以在工作中用有效的方法防止和规避柱塞泵内部精密件的失效和故障,减少液压系统的故障率,提高设备工作效率。
Hydraulic plunger pump is the core component of pressure oil source in hydraulic system, its performance directly affects the efficiency of the whole hydraulic system and even whether it can work continuously and normally. Based on the structural characteristics of precision parts in hydraulic axial piston pump and the working mechanism of three pairs of friction pairs, the basic wear failure forms of precision parts of plunger pump are analyzed and explained. At the same time, the failure causes of precision parts caused by improper working methods are analyzed, and the correct methods of using them are explained. The purpose is to prevent and avoid the failure and failure of the internal precision parts of the plunger pump by understanding its failure principle, and to reduce the liquid in the work. The failure rate of the pressure system improves the working efficiency of the equipment.
