Generally, the oil cylinder of the pipe bending machine leaks because the oil cylinder has not replaced the seal ring for a long time, which causes the seal ring to wear and the seal ring life is limited. Generally, a new seal ring needs to be replaced for about two years or the cylinder is roughed, and the seal ring is worn and damaged. The pipe bender is divided into four control valves and five cylinders. The main oil cylinder drives the movement of the bending arm, and the two clamping cylinders control the clamping mold for clamping. The core pulling cylinder plays the role of core pulling of the mandrel. There is also an auxiliary push to prevent the deformation of the tube and push the tube to bend. . In the daily process of using the pipe bender, you should check whether the pipe bender is leaking at any time. In the face of oil leakage, you should deal with it promptly: remove the oil cylinder and replace it with a new sealing ring. Replace the cylinder, just replace it with a new cylinder and install it!
