Face up to the correct use of the bolt hydraulic wrench tensioner.Air band saw Processing
source:Industry News release time:2021-12-07 Article author:Rosit Popular:Air band saw
The oil pressure must be calculated before the tensioner is used to avoid excessive working pressure, which exceeds the bearing capacity of the bolt (composition: head and screw), causing the bolt (composition: head and screw) to undergo plastic deformation and vandalism. Bolt (composition: head and screw). 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 part. 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. The tensile force (tensile pull) produced by the bolt (composition: head and screw) stretcher is equal to the product of the output pressure of the power source and the effective area of the piston. Therefore, the allowable stress can be calculated according to the strength level of the bolt (composition: head and screw) used, so as to reverse the output pressure of the pump. Ensure that the deformation of the bolt (composition: head and screw) is within elastic degeneration, and complete the work without destroying (vandalism) the bolt (composition: head and screw). In the process of pressurization (guò chéng), pressurization should be as uniform as possible (jūn yún). Every time a certain pressure is increased, the pressure must be stabilized and then increased to avoid excessive impact tension, which will affect the pre-tightening effect of the bolt (composition: head and screw). In the stretching process (guò chéng), attention should be paid to the maximum design stroke of the stretcher. If the maximum stroke is exceeded, the seals may be cut, or a safety accident may occur. Generally, the stretcher has a maximum stroke warning (warning notice) line, and the user is required to pay attention to the maximum stroke at any time during use.
