Hydraulic torque wrench high pressure hose joint should not bend excessively or at the root, at least 1.5 times its diameter. When the high-pressure hose of the hydraulic wrench moves to the limit position, it should not be pulled too tightly, but should be relatively relaxed. Avoid the twist deformation of hose as far as possible. The high-pressure hose of hydraulic wrench should be as far away from the thermal radiation parts as possible, and the heat insulation board should be used when necessary. External damage of hoses should be avoided, such as long-term friction with the surface of parts in use. If the weight of the hose causes excessive deformation, it should be supported.

What are the maintenance precautions for the hydraulic wrench in use?

  1. Attention should be paid to hydraulic wrench in operation: when changing hydraulic oil frequently, the working fluid of hydraulic wrench must be wear-resistant hydraulic oil. Alcohol, water and other substances shall not be used as working fluid for hydraulic wrenches. And wear-resistant hydraulic oil must be clean, pure hydraulic oil can allow the use of hydraulic wrenches. This can extend the life of the wrench.
  2. In order to prevent the hydraulic wrench working fluid from being polluted, it is better to replace the connection between the High pressure hose joint tubing and the threaded joint in the hydraulic system with the threaded joint, so as to effectively prevent the working fluid from being polluted by pollutants.
  3. When the hydraulic wrench works, attention should be paid to keeping the surrounding working environment clean and tidy, avoiding a small amount of oil pollution into the hydraulic wrench, which will affect the working performance and service life of the hydraulic wrench.
  4. For hydraulic wrenches which are not often used, attention should be paid to the dry storage environment, rather than the wet environment. In order to prevent rust on the surface, it is better to apply Vaseline evenly on the surface of the wrench before storage. Then put them in matching boxes and in a dry, ventilated room.
