　　Comparison of hydraulic wrench and ordinary wrench

　　Hydraulic wrenches are referred to as hydraulic torque wrenches. It is powered by hydraulic pressure and provides high torque output. It is used with standard sleeves. It is a professional bolt tightening and dismounting tool used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch.

　　Compared with ordinary wrenches, hydraulic wrenches have the following advantages:

　　One. Hydraulic wrench is easy to use. It can be used with a socket. A wrench and a variety of sockets can be used to install and remove bolts of different sizes (composition: head and screw) and nuts;

　　Second, the hydraulic wrench has a light structure and is easy to carry. It can replace a full set of heavy ordinary wrenches, and it is relatively convenient and quick to replace and replace (meaning: fast and agile);

　　3. It is convenient to operate and control when installing and disassembling nuts or bolts when using hydraulic wrenches. The use of 360-degree rotating tubing joints has less limited operating space and a wider range of use (fàn wéi). The safe operation of hydraulic wrenches can also improve work efficiency ( efficiency).

　　Four, hydraulic wrenches are easier to grasp (familiar and can use) the torque when used, and it is easier to tighten and disassemble than ordinary wrenches, and the efficiency (efficiency) will be higher;

　　5. The hydraulic wrench adopts a precision ratchet, the accuracy is as high as ±3%, which cannot be achieved by ordinary wrenches;

　　6. The hydraulic wrench is made of high-tech aerospace materials and super-strength alloy steel (alloy steel). The body is integrally formed, which comprehensively strengthens the body's strength and toughness. It is not easy Damaged and durable.

　　Because of these characteristics of hydraulic wrenches, in high-precision (precision) and high-strength (strength) manufacturing enterprises, hydraulic wrenches have gradually (step by step) begun to replace ordinary wrenches, not only can reduce operation control The physical strength and energy of the participants have simplified the work process and greatly improved the work efficiency. The hydraulic wrench transmits power to the working head through the high-pressure oil pipe and the hydraulic pump, which drives the working head to tighten or loosen the nut. The hydraulic pump can be driven by electricity or compressed air. 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 component is the hydraulic wrench amplification arm. The oil cylinder output multiplied by the arm is the theoretical output torque of the hydraulic wrench. The actual output torque is smaller than the theoretical output torque. Understand (Find out) the basic common sense of hydraulic wrench, you can better perform service production (Produce) processing.
