The working principle of hydraulic wrench

Hydraulic wrench by hydraulic power, provide high torque output, used for the installation of the bolt and remove the bolt tightening tools, often used for tightening bolts and break loose is more than an inch. Hydraulic torque wrench maximum output torque of 110000 nm, not only improve the work efficiency, reduce the labor intensity, and greatly improve the quality of installation, also is advantageous to the site safety management. The use of hydraulic wrench very extensive. In Marine engineering, petrochemical industry, building, electric power, mining, metallurgical industries such as construction, maintenance and repair work, such as hydraulic wrench for large size bolt installation and removal is a very important tool. Have the property of other tools can not be replaced. Not only easy to use and lighter, and the torque provided huge and very accurate. Torque repeat accuracy is + / - 3%. According to the statistics, about 50% in the equipment operation fault was caused by a bolt problem, at the same time the equipment the number of major accidents caused by bolt problem also is terrible, so in equipment installation, maintenance and gun in the process of repairing on the bolts and remove the torque in the vast majority of cases are more strict, and methods of choose and employ persons worker worker is hard to meet the requirements. Provide the output torque of the large size for bolts, the hydraulic wrench is an ideal choice.
