  AW21-600 Pneumatic impact wrench

  Nm is torque unit, psi is pressure unit, hydraulic wrench nm and no direct correspondence between the psi, need to have a distance to conversion, pump output pressure in hydraulic wrench to into torque output, it is through the oil cylinder pressure wrench to push the piston to complete, and specific hydraulic wrench nm into psi, General Wharton hydraulic wrench will provide "pressure-torque comparison table" provided to the user, the user can according to their required torque value to find out the corresponding need psi value.

  Hydraulic wrench torque pressure conversion method:

  1. Known conditions: bolt tension F, bolt diameter M

  N M: torque value Nm=F(KN)×M(mm)× coefficient 0.16

  Assumption: the bolt tension is 70 tons and the bolt is M52
