徐工在RP751等型号摊铺机上应用两位四通电磁换向阀之后收到了很好的效果。1.控制液压缸往复运动两位四通电磁换向阀能改变油液的流动方向,从而控制液压缸活塞杆的往复运动。图1中,电磁阀1和2分别控制摊铺机的大臂支撑缸和油门缸。通过电磁铁的通、断改变A1、B1和A2、B2高、低压腔
Xugong RP751 paver and other models in the application of two four-way solenoid valve received good results. 1. Control of reciprocating hydraulic cylinder Two-position four-way solenoid valve can change the flow direction of oil to control the hydraulic cylinder reciprocating rod. In FIG. 1, the solenoid valves 1 and 2 respectively control the boom support cylinder and the throttle cylinder of the paver. Through the electromagnet pass, off change A1, B1 and A2, B2 high and low pressure chamber
