Imported hydraulic wrench pump pressure should be stable.hydraulic impact wrench company
source:Industry News release time:2021-12-15 Article author:Rosit Popular:Air band saw
Imported hydraulic wrench pump pressure stability is extremely important, everyone must pay attention to this aspect of the problem, in order to better ensure the stability of the hydraulic wrench pump, let's take a look together below.
The stability of the hydraulic wrench pump pressure will directly affect the accuracy of the output torque of the hydraulic torque wrench. Unstable output pressure will also have a negative impact on the service life of the hydraulic torque wrench and the service life of the disassembled nut, as well as hydraulic shock hazards. .
1. 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 torque of the hydraulic torque wrench to be unstable, which will affect the locking of the bolts. The torque is unstable, causing potential hazards to the installation of the equipment;
2. Due to the fluctuation of the output pressure of the hydraulic torque wrench pump, the fluctuation of the output torque will be changed, which will cause a mechanical shock between the relative moving parts of the hydraulic torque wrench. This mechanical shock will directly shorten the movement accuracy and The service life will eventually shorten the service life of the entire hydraulic torque wrench;
3. We all know that after many maintenance and disassembly of the nut, the hexagonal surface of most nuts will fail, causing it to be impossible to tighten and scrap. The same reason as the second is that the change in the output torque of the hydraulic torque wrench will also be caused by the sleeve and lock. A mechanical impact is generated between the tightening nuts, which breaks the hexagonal surface of the tightened nut and causes the nut to fail.
