一、压力冲击的产生首先,简述一下张力放线的工作原理。如图1所示:在牵引机牵引力的作用下,导线8带动双摩擦卷筒1转动。通过减速机2(此时减速机作为增速机运行)驱动液压油泵4,液压油泵4输出液压油给溢流阀6,控制溢流阀6的工作压力即控制了液压油泵的工作压力,也就控制了导线的张力。 First, the emergence of pressure shock First, briefly describe the working principle of tension line. As shown in FIG. 1 , under the action of the traction force of the tractor, the wire 8 drives the double friction drum 1 to rotate. The hydraulic oil pump 4 is driven by the speed reducer 2 (in this case, the speed reducer operates as a speed increaser), and the hydraulic oil pump 4 outputs hydraulic oil to the relief valve 6, and the working pressure of the relief valve 6 is controlled to control the working pressure of the hydraulic oil pump. It controls the tension of the wire.
