The internal structure and working principle of hydraulic wrench
source:Industry News release time:2022-07-13 Article author:yu Popular:Air band saw
1. Internal structure of hydraulic wrench: The internal structure of hydraulic wrench is composed of reaction arm, ratchet, pawl, drive shaft and rotary joint.
2. Working principle of hydraulic wrench: Hydraulic torque wrench is composed of working head, hydraulic pump and high-pressure oil pipe. The working head of the hydraulic wrench is mainly composed of three parts, the frame (also called the shell), the oil cylinder and the transmission parts. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair, the distance from the center of the oil cylinder to the center of the transmission part is the hydraulic wrench amplifying force arm, and the output of the oil cylinder multiplied by the force arm is the theoretical output torque of the hydraulic wrench. The actual output torque is less than the theoretical output torque. After the hydraulic wrench pump is started, the internal pressure is generated by the motor motor, and the internal hydraulic oil is transmitted to the hydraulic wrench through the oil pipe medium, and then the piston rod of the hydraulic wrench is pushed, and the piston rod drives the ratchet at the front of the wrench, so that the ratchet can drive the drive shaft. A process to complete the pre-tightening of bolts.
Because hydraulic wrenches are often used in small spaces and inconvenient locations during construction, the volume and weight of the wrench are relatively important indicators. In order to reduce the size of components, the use of high-strength alloy materials and heat treatment are common methods. Wharton hydraulic wrench is made of high-tech aerospace aluminum-titanium alloy material. I believe you have mastered the relevant content of "Internal Structure and Working Principle of Hydraulic Wrench". If you have any unclear points in the subsequent use process
