reciprocating movement meaning in English

往复运动

Motor with reciprocating movement
往复运动电动机
For separated push rod , switch on , under no - load condition , the oil cylinder makes reciprocating movement for several times , to discharge air in the cylinder and oil pipeline , then adds load
分体推杆，接上电源让油缸在无负载情况下，往复动作数次使油缸和油管中空气排出、再带上负载。
Electrohydraulic push rod drives the two - way pump to output pressure oil with rotation of motor clockwise and counter - clockwise , by control of hydraulic valve , send to the hydraulic cylinder , to achieve the reciprocating movement of the piston rod
电液推杆以电动机正反转，带动双向泵输出压力油，经液压阀控制，送至液压缸，实现活塞杆的往复运动。
As well known the shock absorber is a key part of auto & motorcycle that is easy to be failure . the guide bushing & piston rod is also easy to fail mostly in the shock absorber . therefore it is very important practical and theoretical meaning to study friction & wear mechanism during this reciprocating movement
减振器是汽车、摩托车中一个关键的易损零部件，主要是内部导向套?活塞杆这对往复运动摩擦副的失效导致，因此研究此类型往复运动的摩擦磨损机理具有十分重要的实际意义和理论意义。
