摘要
一个液压系统在某处都会或多或少的产生一定的压降,但压降在某处是必须的,在某处是不必要的。很多液压系统故障的根本原因就是由压降没有合理解决引发的。通过该文的分析,提出合理的运用(压降必须处)﹑控制压降(压降不必要处)的方法,使液压系统设计更合理,减少液压系统故障率,提升液压系统有效效率。
A hydraulic system somewhere will be more or less produce a certain pressure drop,but the pressure drop is necessary somewhere and it is unnecessary somewhere.The root causes of the many hydraulic system failures are triggered by the unreasonable pressure drop.Through the analysis in this paper,the methods of reasonable use （as necessary） and control of pressure drop （as unnecessary） are proposed to make the hydraulic system design more reasonable,reduce hydraulic system failure rate,and enhance the effective efficiency of the hydraulic system.
