Intelligent hydraulic wrench is composed of body, intelligent electric hydraulic pump, double high pressure oil pipe and high strength sleeve. After the intelligent hydraulic pump is started, the pressure is generated by the motor, and the internal hydraulic oil is transmitted to the intelligent hydraulic wrench through the oil pipe medium, and then the piston rod of the intelligent hydraulic wrench is pushed. The piston rod drives the ratchet wheel at the front of the wrench, so that the ratchet wheel can drive the drive shaft to complete the pre tightening and loosening of the bolts.
The special pump for hydraulic wrench can be driven by electric or pneumatic.
The body of the hydraulic wrench is mainly composed of three parts, the body (also known as the shell), oil cylinder and transmission parts. The distance between the center of the oil cylinder and the center of the transmission part is the amplification arm of the hydraulic wrench. The output of the oil cylinder multiplied by the force arm is the theoretical output torque of the hydraulic wrench.
