When a hydraulic wrench is used, various faults (faults) of the hydraulic wrench are often caused due to the operation control method or the working environment, which brings more inconvenience to the production (Produce) at this time. Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is a professional bolt tightening tool that is powered by hydraulic pressure and provides high torque output. It is used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Therefore, when the mechanic finds out the work performance advantages of hydraulic wrenches (explanation: can overwhelm the opponent’s favorable situation), he also needs to pay attention to the troubleshooting of hydraulic wrenches (chǔ lǐ), so that the hydraulic wrench can be used. Show the inherent ability) the best performance, to bring substantial help for production.

The common faults of hydraulic wrenches are mainly manifested in two aspects: particularly high-strength work causes deformation of the cylinder sealing ring, oil leakage and pressure increase, etc.; machine maintenance and repair are not In place, there is weakness or failure to work.

　　For the former, the main reason is that the hydraulic wrench operation control method is incorrect, the wrench is not used properly, the working time is too long or the working intensity is too large to exceed the load of the hydraulic wrench, which causes the internal damage of the hydraulic wrench and the serious oil leakage of the wrench.

On the other hand, the long-term use of hydraulic wrenches (a basic type of component failure) is large, the components are not updated in time, and the maintenance is not in place, causing the machine to rust or loosen. When the hydraulic wrench is weak or inflexible to use, it cannot meet the needs of the production (Produce), and the ratchet and pawl parts are severely damaged. In this regard, it is necessary to remind the operation control master to pay attention to the daily maintenance, maintenance and repair of the hydraulic wrench, and the best maintenance of the machine can increase its lifetime.
