Damage of O-ring of hydraulic wrench during installation.Air impact wrench price
source:Industry News release time:2022-02-14 Article author:Rosit Popular:Air band saw
Reason: This situation often occurs in dynamic seals and static seals. The main reason is that the edges of the sealing groove are angular, which does not meet the standard. When installing, do not apply lubricating oil, so that the sealing ring is divided, twisted or jammed by sharp edges, and the surface is concave or convex.
Solution: According to the design requirements, process the sealing groove without leaving sharp edges. 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. During installation, lubricating oil can be applied to the groove (meaning: the recessed groove on the surface of the object) and the sealing ring. When the hydraulic wrench O-wrench is threaded, the metal band or steel band can be sleeved on the thread, so that the sealing ring can be inserted smoothly.
