在中央试验室对一系列的液压设备进行符合要求的检验,内部零件在维修拆卸时进行常规的检验。遗憾的是没有保存设备的各种零件的原始详细数据,因而就不可能定出这些零件的使用寿命。英国煤炭研究院中央试验室在模拟工况试验期间,检验了被侵蚀液压设备的元件,并作出了完整的统计资料,调查结果汇总于表1中。冲蚀术语“冲蚀”常用来描述许多种磨损机理,但在液压设备中可能有三种主要类型: 气蚀——在液压高速流体中气泡的破灭而引起的材料剥离,这情况通常发生在节流 A series of hydraulic equipment in the central laboratory to carry out the required inspection, internal parts during maintenance and disassembly for routine inspection. Unfortunately, the original details of the various parts of the equipment are not saved, so it is impossible to determine the useful life of these parts. British Coal Research Institute of the Central Laboratory test conditions during the simulation of the hydraulic equipment has been erosion of components and made a complete statistical data, the survey results are summarized in Table 1. Erosion The term “erosion” is often used to describe many types of wear mechanisms but there are three main types of hydraulic equipment possible: Cavitation - material delamination caused by the collapse of bubbles in a hydraulic high-velocity fluid, flow
