In the use of hydraulic pipe bending machine, sometimes there will be a machine oil leakage, which affecting the use of the pipe bending machine. So how to solve the problem of hydraulic pipe bending machine oil leakage?
1.In the hydraulic pipe bending machineback to the pool of oil on the end of the cover to dig a small hole and weld a shut-off valve in the operation of the operation of the shearing machine operating procedures on the addition of another: the shut-off valve should be closed when the power on, each time after the end of the shear and immediately open the valve in order to facilitate the leakage of nitrogen leakage to the pool of nitrogen discharged into the atmosphere in a timely manner.
2.When the manual button or foot switch is released, at this time the hydraulic oil in the lower post is pressed back to the oil pool by the downward movement of the piston of the nitrogen accumulator and the piston of the main cylinder is moved upward through the oil circuit to make the cutter frame rise, and the hydraulic oil in the upper chamber is returned to the oil pool through the main circuit.
3.When it is found difficult to lift the tool holder, the accumulator should be replenished with nitrogen.
4.Replace the O-ring in the accumulator with nitrogen if the tool holder lifts very slowly.
5.Replace the piston in the accumulator when nitrogen filling is frequent.
