The main reasons for low oil pressure, reduced or interrupted oil supply in the lubricating oil system of Roots fan and the solutions to deal with them.
The main reasons are divided into the following five points:
- Oil ring bearing box oil amount is too much or too little, or oil ring manufacturing quality is too poor, so that the oil ring can not rotate or with oil is too small. At this time, the oil volume should be adjusted, repair or replace the oil ring.
- The oil level in the tank drops below the minimum level. At this time, refueling should be done immediately to raise the oil level.
- The lubricant in the hydraulic pump or tubing freezes during parking. In this case, the frozen lubricant should be replaced and cleaned.
- Bearing installation will be installed in the direction of the liner inlet reverse or for the right, bearing lubricant inlet at the throttle ring aperture is too small or blocked. At this time, the bush should be re-anchored, increase the aperture of the throttle ring, remove dirt.
- Gear hydraulic pump, oil cooler or piping on the failure of the machine parts. At this point, should be poorly clear reasons, respectively, to deal with.
