Maintenance of Hydraulic Torque Wrench Parts
As a special tool for fastening or loosening nuts, Hydraulic torque wrench has different degrees of wear after high-strength and high-pressure work. Therefore, when completing the work induction, it is not only necessary to handle with care, not to bump at will, but also to maintain and clean the wrench parts regularly.
1. Spring care: springs are installed between the driving pawl and the reaction pawl. The springs in these positions are easy to wear, and once they are damaged, they can not be repaired, so they can only be replaced. So regular inspection is very important, the time is generally two years to check and replace once.
2. Sealing device of oil cylinder: once the oil cylinder leaks, it can’t work, so it is necessary to check the sealing state of oil cylinder regularly. If oil leakage is found, the sealing ring and other components with problems should be replaced.

3. Wrench structure: check whether it is damaged, deformed or broken every year, and replace the structure if there is any problem. The rotary joint on the hydraulic wrench should also be checked regularly. If there is leakage, the seal should be replaced. If there is damage, the rotary joint should be replaced.
4. Regular cleaning of parts: clean all the parts with cleaning solution, but soak them with non corrosive immersion solution, and finally clean and wipe them with hydraulic oil（ Xiaobian is usually cleaned with diesel oil, then dried and assembled. Before assembly, apply a thin layer of hydraulic oil.)
5. Remember not to drag the oil pipe with wrench on the ground at will, which will not only cause oil leakage at the joint of the oil pipe, but also damage the external protective layer of the oil pipe, reduce the service life of the oil pipe and affect the normal work in the future.
Although hydraulic torque wrench seems to be omnipotent and hard, it needs careful care and maintenance to work and use for a long time. Therefore, the maintenance of hydraulic wrench parts should not be underestimated, and parts are also an important part of the normal work of hydraulic wrench.
