液压扳手是液压力矩扳手简称。是以液压为动力,提供大扭矩输出,
用于螺栓的安装及拆卸的专业螺栓上紧工具,经常用来上紧和拆松大于一英寸的螺栓。
液压扳手是由工作头、液压泵以及高压油管组成。
通过高压油管,液压泵将动力传输到工作头,驱动工作头旋转螺母的拧紧或松开。液压泵可以由电力或压缩空气驱动。
液压扳手的工作头主要由三部分组成,框架(也叫壳体),油缸和传动部件。油缸输出力,油缸活塞杆与传动部分组成运动副,油缸中心到传动部件中心这个距离是液压扳手放大力臂,油缸出力乘以力臂,就是液压扳手理论输出扭矩,由于摩擦阻力存在,液压扳手实际输出扭矩要小于理论输出扭矩。
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.
