Hydraulic wrench

Put the hydraulic wrench and torque sensor on the middle table of the torque measurement and verification, and connect the three with a rotating shaft and the conversion connector. During the connection, be sure to keep the operating table firm and not messy, and make the torque sensor and the hydraulic wrench torque center line persist in level and strictly require the coaxial line. After adjusting the parts between each other, fix the end of the hydraulic wrench support arm and the countertop of the working cabinet to ensure that the two do not cause the parts between each other to move during the application of force on the hydraulic wrench.

As the torque value of the hydraulic wrench, appropriately select the measurement range of the standard torque sensor. Before the device, you must distinguish the zero position of the pressure gauge of the adjusting specification device and the hydraulic wrench.

Add the hydraulic wrench appropriately on the specification device, and then gradually and stably apply it to the rated torque value according to the selected metering and verification point, and read and record the torque value of each point. This technical specification is carried out at least three times. After each time the rated torque value is applied, the load is removed, the specification device and hydraulic wrench instigator return to zero, and the zero position is newly adjusted.
