日立建机公司研制出一种检测液压泵故障的装置(HICLAS-A)。这一装置适用于检验液压式铲车或起重机等建筑机械上所用的轴向柱塞泵。它是靠振动变化来检测其损伤程度,并通过微型电算机来分析处理判断故障的设备。其特点是,不象过去那样,把泵拆开,而是从外部简单地在短时间内就能检测结果的基础上,推断出该泵的使用寿命。近来,检测故障 Hitachi Construction Machinery has developed a hydraulic pump failure detection device (HICLAS-A). This device is suitable for testing axial piston pumps used in construction machinery such as hydraulic forklift trucks or cranes. It is based on changes in vibration to detect the extent of its damage, and through the microcomputer to analyze and process equipment to determine the fault. Its characteristic is, unlike in the past, the pump apart, but from the outside simply in a short period of time can detect the results based on the estimated service life of the pump. Recently, the problem was detected
