1故障诊断的一般原则1.1检查液压系统工作环境正确的工作环境和工作条件是液压系统正常工作的前提。液压系统要正常的工作,需要一定的工作环境和工作条件作平台,如果工作环境严重不符合该系统正常工作的标准,想要系统不出现故障几乎是不可能的,所以在故障诊断之初我们就应该首先判断并确定液压系统的工作条件和外围环境是否正常。 A general troubleshooting principle 1.1 Check the hydraulic system working environment Correct working conditions and working conditions are the premise of the hydraulic system to work properly. Hydraulic system to normal work, the need for a certain working environment and working conditions for the platform, if the work environment is serious does not meet the normal working standards of the system, it is almost impossible to system failure does not appear, so at the beginning of fault diagnosis we It should first determine and determine the hydraulic system working conditions and the external environment is normal.
