Stability of hydraulic wrench in use of pump station pressure.Hollow hydraulic wrench
source:Industry News release time:2022-04-06 Article author:Rosit Popular:Air band saw
The stability of the output pressure of the hydraulic wrench pump station will directly affect the accuracy of the output torque of the hydraulic torque wrench, and will also have a negative impact on the service life of the hydraulic torque wrench and the service life of the disassembled nut, and will also cause hydraulic shock hazards. .
After the nut has been repaired and disassembled for many times, the hexagonal surface of most nuts will fail, causing it to be scrapped because it cannot be tightened. Same as the second point, the change of the output torque of the hydraulic wrench will also produce a mechanical impact between the sleeve and the lock nut. , thereby destroying the hexagonal surface of the locked nut, causing the nut to fail, and the unstable pressure of the hydraulic wrench pump will greatly shorten the number of times the equipment bolts can be disassembled and repaired.
The thrust of the hydraulic cylinder F=PxA, when the output pressure P of the hydraulic pump station is unstable, it is obvious that the output force F of the hydraulic cylinder will fluctuate, resulting in the instability of the output torque of the hydraulic torque wrench, thus affecting the tightening torque of the bolt. Stable, causing potential hidden dangers to the installation of the equipment;
Due to the fluctuation of the output hydraulic pressure of the hydraulic wrench, the fluctuation of the output torque will be changed, so that a mechanical impact will be generated between the relative moving parts of the hydraulic torque wrench. This mechanical impact will directly shorten the movement accuracy and service life of the parts. Ultimately, the life of the entire hydraulic torque wrench is shortened.
