The delay of pressure switch in the hydraulic system and the precaution measures

TANG Kai-yong(Hunan Metallurgy Professional Technology Institute,Zhuzhou 412000,China)  
The delay of pressure switch is a control problem which usually occurs in the hydraulic systems.It always reflects in that the pressure change on the machine does not fit in with the requirement of the practical control.The inappropriate maintenance of the overflow valve,the pressure adjust valve,the change over valve and the release valve(卸荷阀)in the hydraulic system can lead to the sluggish movement of the valve fuse,which will then cause the delay of pressure switch.Furthermore,the hydraulic system lacking of rigidity can also lead to the delay of pressure switch.The timely maintenance and repair of the related valves,and promoting the rigidity of the system are the basic precaution measures to delay of pressure switch.In the hydraulic system.
