[0002] A hydraulic wrench is a tool that tightens bolts through the action of hydraulic pressure. It uses the hydraulic principle to convert hydraulic energy into mechanical energy, thereby achieving torque transmission and completing the work. The principle is that when the hydraulic pump is started, hydraulic oil is pumped into the hydraulic cylinder, causing the piston to move forward. The pressure of the hydraulic oil is transmitted to the wrench head through the piston, generating torque. By adjusting the pressure of the hydraulic oil, the size of the torque can be controlled. When the hydraulic pump stops working, the hydraulic oil is prevented from flowing, the piston stops moving, and the torque on the wrench head also stops being generated.
