谈林业机械维修测试技术分析 　　Talk about forestry machinery maintenance test of the technical analysis 　　LuChunYing 　　The new forest forest new Lin masses do 　　Abstract: the hydraulic system of testing and commissioning including whole no-load debugging and load test. In the specific test before going to completely check the commissioning of the loader hydraulicsystem installation is correct, the hydraulic pipe is correct and reliable, hydraulic oil brand is correct, whether to conform to the cleanliness requirements, the height of the oil tank in compliance with requirements, determine the correct, conducted only after the whole debugging. 　　Keywords: loader maintenance technology 　　A, hydraulic pressure system of performance requirements 　　Hydraulic system can pressure, flow rate, and the adjustment of the work location, etc, in order to make component or system reaches the technical index; Maintenance and repair is to make components or every technical indicator of the system can meet the requirements of the loader normal work, and can eliminate or avoid the potential failure point. Hydraulic system mainly including hydraulic components and hydraulic system. The maintenance of hydraulic components and detection, in order to guarantee the accuracy of the test and the reliability, to test equipment is perfect, environment in good laboratory or the workshop; The hydraulic system of the adjustment of the whole, usually in the host, in order to make full use of the existing equipment and mechanical equipment, meanwhile, ensure hydraulic system for the whole host adaptability. 　　Second, hydraulic components of the test 　　1, power components of the test. Loader power components of hydraulic pump is mainly. Hydraulic pump is mainly detected work pressure and flow two performance parameters. The test shall be in hydraulic pump nominal rated speed, through the pressure gauge and flow measurement is in the concrete pump rated speed of output under the pressure and flow. Specifi
