The importance of pressure stability in hydraulic wrench pumping stations.Pneumatic Pump company
source:Industry News release time:2021-12-14 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. It will also have a negative impact on the service life of the hydraulic torque wrench and the service life of the disassembled nut, and it will also produce hydraulic shocks. harm.
The output is unstable, which seriously affects the service life of the bolt: after the nut has been repaired and disassembled for many times, the hexagonal surface of most nuts will fail, causing it to be unable to be tightened and scrapped. Moreover, the change of the output torque of the hydraulic wrench will also produce mechanical impact between the sleeve and the locking nut, which will damage the hexagonal surface of the locked nut to a certain extent, causing the nut to fail, and will greatly reduce the number of times the equipment bolt can be removed for maintenance.
Unstable output pressure causes potential hazards to the installation of the equipment: the thrust of the hydraulic cylinder F=PxA, when the output pressure P of the hydraulic pump station is unstable, obviously the output force F of the hydraulic cylinder will also fluctuate, which will cause the output of the hydraulic torque wrench. The instability of the torque affects the instability of the tightening torque of the bolts and causes potential hazards 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, which will cause mechanical shock between the relative moving parts of the hydraulic torque wrench. This mechanical shock will directly shorten the movement accuracy and service life of the parts. Ultimately, the life span of the entire hydraulic torque wrench is shortened.
