hydraulic wrench pressure conversion
source:Industry News release time:2022-10-10 Article author:yu Popular:Air band saw
In recent years, hydraulic wrenches have been used by many industrial and mining machinery companies and play an important role in disassembling and tightening bolts. However, there are still many people who do not know what is the method of converting the torque and pressure of the hydraulic wrench. Today, Wharton Hydraulic Wrench will tell you in detail how to convert torque and pressure of hydraulic wrench.
1. Torque and pressure conversion of hydraulic wrench - an introduction to torque and pressure units
nm is the torque unit, and psi is the pressure unit. There is no direct correspondence between the conversion of nm to psi in the hydraulic wrench. A distance value is required to convert. The output pressure of the hydraulic wrench pump station needs to be converted into torque output. Use the wrench cylinder to push the piston to complete, and the specific hydraulic wrench nm is converted into psi. Generally, Wharton hydraulic wrench will provide the "pressure-torque comparison table" to the user. The user can find out the corresponding needs according to the torque value they need. psi value.
Second, the hydraulic wrench torque pressure conversion method:
1. Known conditions: bolt tension F, bolt diameter M
Calculate the torque value N.m required for the bolt: torque value Nm=F(KN)×M(mm)×factor 0.16
Assumption: The bolts require a pulling force of 70 tons, and the bolts are M52
2. Calculation:
(70×9.8)KN×52mm×0.16(coefficient)=5707.5Nm
