2018 Key Reminder: Four Inspection Items for Angle Roller Work
Common faults of angle roller in daily work:
- Check the domination valve. First clean the safety valve and check if the valve core can wear out. If angle roller is worn, replace it. If there is no change after the safety valve device, check the valve valve wear condition of the domination valve. The gap application limit is 0.06 mm, and the wear should be changed seriously.
- Masure the pressure of the hydraulic pump. If the pressure is too low, stop the adjustment and the pressure will not be adjusted. Explain the serious wear of the hydraulic pump.
- Check the internal leakage of the hydraulic cylinder of the boom profile stretcher. The easiest way is to raise the boom to see if there is a clear and comfortable landing. If the drop is obvious, check the pull-bending machine's cylinder. If the seal ring has worn, it should be changed.
- When the body of the angle roller, the grinding head and the frame connection bolt should be tightened.
