Hydraulic wrench (hydraulic torque wrench, referred to as hydraulic wrench) is a professional bolt tightening tool used for bolt installation and disassembly, which is powered by hydraulic pressure and provides high torque. It is often used to tighten and loosen bolts larger than M20. The maximum output torque of the hydraulic torque wrench can reach 110000Nm, which not only improves work efficiency and reduces labor intensity, but also greatly improves installation quality and is also conducive to site safety management.
The scope of use of hydraulic wrenches is very wide. In shipbuilding, petrochemical, construction, electric power, mining, metallurgy and other industries, hydraulic wrenches are a very important tool for the installation and disassembly of large-size bolts. It is irreplaceable with other tools. Not only is it easy to use and light, but the torque provided is huge and very accurate. The torque repeatability is about 3%. According to relevant statistics, about 50% of equipment operation failures are caused by bolt problems. At the same time, the number of major equipment accidents caused by bolt problems is also very staggering. Therefore, tighten the bolts during equipment installation, maintenance and gun repair. The torque for fixing and disassembly is strict in most cases, and it is difficult to meet the requirements with manual methods. For bolts that provide large torques, hydraulic wrenches are the ideal choice.
The hydraulic torque wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Through the high-pressure oil pipe, the hydraulic pump transmits the power to the working head, and drives the working head to tighten or loosen the nut. The hydraulic pump can be driven by electricity or compressed air.
The working head of the hydraulic wrench is mainly composed of three parts, the frame (also called the shell), the oil cylinder and the 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 component is the arm of the hydraulic wrench. The output of the oil cylinder multiplied by the arm is the theoretical output torque of the hydraulic wrench. The actual output torque is smaller than the theoretical output torque.
