  • 液壓扳手是干什么用的?

液壓扳手是液壓力矩扳手簡(jiǎn)稱。是以液壓為動(dòng)力,提供大扭矩輸出,
用于螺栓的安裝及拆卸的專業(yè)螺栓上緊工具,經(jīng)常用來上緊和拆松大于一英寸的螺栓。
液壓扳手是由工作頭、液壓泵以及高壓油管組成。
通過高壓油管,液壓泵將動(dòng)力傳輸?shù)焦ぷ黝^,驅(qū)動(dòng)工作頭旋轉(zhuǎn)螺母的擰緊或松開。液壓泵可以由電力或壓縮空氣驅(qū)動(dòng)。
液壓扳手的工作頭主要由三部分組成,框架(也叫殼體),油缸和傳動(dòng)部件。油缸輸出力,油缸活塞桿與傳動(dòng)部分組成運(yùn)動(dòng)副,油缸中心到傳動(dòng)部件中心這個(gè)距離是液壓扳手放大力臂,油缸出力乘以力臂,就是液壓扳手理論輸出扭矩,由于摩擦阻力存在,液壓扳手實(shí)際輸出扭矩要小于理論輸出扭矩。
Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is powered by hydraulic pressure to provide large torque output,
A professional bolt tightening tool for bolt installation and disassembly, which is often used to tighten and loosen bolts greater than one inch.
The hydraulic wrench is composed of working head, hydraulic pump and high-pressure oil pipe.
Through the high-pressure oil pipe, the hydraulic pump transmits power to the working head to drive the tightening or loosening of the rotating nut of the working head. The hydraulic pump can be driven by electricity or compressed air.
The working head of hydraulic wrench is mainly composed of three parts: frame (also known as shell), oil cylinder and transmission parts. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair. The distance from the center of the oil cylinder to the center of the transmission part is the amplified force arm of the hydraulic wrench. The output of the oil cylinder multiplied by the force arm is the theoretical output torque of the hydraulic wrench. Due to the existence of friction resistance, the actual output torque of the hydraulic wrench is less than the theoretical output torque.
