What are the common failure causes of single-head hydraulic pipe benders

Feb 25,2021
First, the piston rod of the single-head hydraulic pipe bender stretches out a certain length and shakes the handle, and the top rod stretches and shrinks. Treatment method: the oil filler plug is not loosened, and the oil outlet valve port in the pump body is not sealed. The oil outlet valve steel ball is not rounded. There is waste in the oil. Clean the engine oil and replace the steel ball. Oil leakage at the piston rods of the large and small pumps. Treatment: Damaged sealing ring Replace the sealing ring in the spare parts bag.
     Oil leakage at the switch. Solution: The pressure ring inside the switch is too loose. After removing the limit screw and switch, tighten the pressure ring. The ejector rod is weak and unable to work.
     What should we do in general? If the steel ball in the switch is not well sealed, and the top of the single-head hydraulic pipe bender does not hold the steel ball or drop the steel ball, we can add a steel ball, and then exchange the steel ball to tighten the switch.

  • How to carry out load test on pipe bending machineJan 22,2024
    Bending pipes are important components commonly used in various industrial boundaries, and pipe bending machines are generally used for bending. Pipe bending machines can generally be divided into CNC pipe bending machines
  • Where is the CNC pipe bending machine used?Jan 18,2024
    The CNC pipe bending machine can bend hoops or ribs, and the steel bars can be directly cut and bent by the CNC machine according to the charging and discharging frame.
