在设计一台机器,一种部件或一个元件时,除了要考虑其性能和可靠性以及寿命,还要考虑使用维修方便,特别是节省维修时间。液压元件采取插装式结构就是实现这种设计思想的措施之一。叶片泵有插装式的。如果泵出故障,只要拆开泵盖,取出泵的心脏部分(转子和定子组件),换上新组件即可。油管、联轴节等机械连接部分都不必动。液压缸缸套密封环部分也有插装式的。当更换活塞杆密封环时,先拆掉活塞杆端部的耳环,取出密封插装组件,然后更换密封环。这不必使用大板手把整个缸套完全拆下。阀也有插装式结构,而且结构型式很多。
In designing a machine, a component or an element, in addition to taking into account its performance and reliability as well as its lifetime, but also consider the use of easy maintenance, in particular, to save maintenance time. Hydraulic components to take the plug-in structure is one of the measures to achieve this design idea. Vane pump cartridge type. If the pump fails, simply remove the pump cover, remove the heart of the pump (rotor and stator assembly), and replace with a new one. Tubing, couplings and other mechanical connections do not have to move. Cylinder cylinder seal ring part also has a cartridge type. When replacing the piston rod seal ring, first remove the earrings from the end of the piston rod, remove the seal insert assembly, and then replace the seal ring. This eliminates the need to use a large wrench to completely remove the entire cylinder liner. Valve also has a plug-in structure, and the structure of many types.
