2次液壓扳手是由本體、電動(dòng)液壓泵、雙聯(lián)高壓油管、高強(qiáng)度套筒組成。液壓泵啟動(dòng)后通過馬達(dá)產(chǎn)生壓力，將內(nèi)部的液壓油通過油管介質(zhì)傳送到液壓扳手，然后推動(dòng)液壓扳手的活塞桿，由活塞桿帶動(dòng)扳手前部的棘輪使棘輪能帶動(dòng)驅(qū)動(dòng)軸來完成螺栓的預(yù)緊拆松工作。
Hydraulic wrench is the abbreviation of hydraulic torque wrench. High torque is used to provide power.
Secondary hydraulic wrench is generally composed of hydraulic wrench body, special pump station for hydraulic wrench, double high-pressure hose and high-strength heavy sleeve.
The special pump for hydraulic wrench can be driven by electric or pneumatic.
The secondary hydraulic wrench is composed of body, electro-hydraulic pump, double high-pressure oil pipe and high-strength sleeve. After the hydraulic pump is started, the pressure is generated by the motor to transmit the internal hydraulic oil to the hydraulic wrench through the oil pipe medium, and then push the piston rod of the hydraulic wrench. The piston rod drives the ratchet in front of the wrench, so that the ratchet can drive the drive shaft to complete the pre tightening and loosening of the bolts.
