十年来液压测试技术的发展,主要表现在普遍采用计算机技术。除了常规的几个主要参数的测试仪器有了进一步的发展外,特别是在寻求在线测试液压系统的污染度以及测量泵和阀的主要参数的元件专用测试系统,均有不少新发展。此外,对液压系统的监测和故障诊断也是近几年的热门研制对象。1.压力测量固定式数字式压力表已很普遍,但值得一提的是某些携带式压力测试仪。这种仪器一般有两个压力传感器片附温度传感器。使用这种仪器可以测量两个测压点的压力或压
Ten years of development of hydraulic test technology, mainly in the widespread use of computer technology. In addition to further development of conventional test instruments for several major parameters, there have been many new developments in the field of component-specific test systems that seek to test the on-line contamination of hydraulic systems and to measure the main parameters of pumps and valves. In addition, the hydraulic system monitoring and fault diagnosis is also a hot development object in recent years. 1. Pressure measurement Fixed digital pressure gauge has been very common, but it is worth mentioning that some portable pressure tester. This kind of instrument generally has two pressure sensor pieces to attach the temperature sensor. With this instrument it is possible to measure the pressure or pressure at both pressure points
