Running Roots Blower There will also be some small faults, which must be found and eliminated in time. According to experience, there are generally several aspects. 1. Small air volume and high current
When there are many foreign matters such as dust trapped in the air inlet filter, the air inlet will be affected, causing the motor current to increase and the air volume to decrease. At this time, the filter screen should be replaced or cleaned.
2. Low air volume and current
At this time, check whether the speed regulation function of the frequency converter is invalid and whether the display frequency is inconsistent with the actual situation. Also check whether the drive belt is too loose and slipping.
3. High current and pressure
When the air outlet pipe is blocked or the valve fails, the air outlet is not favorable. At this time, check whether there are obstacles blocking the pipeline, check whether the square valve plate falls off, and timely repair, clean up, and eliminate the fault. If the pressure exceeds the limit, the limit vent pressure of the safety valve shall be set. 4. Belt slipping or belt powder falling
Belt slippage will shorten the life of the belt on the one hand, and will also reduce the fan speed. If such problems are found during patrol inspection, they should be tightened in time; If the end of the belt is found, it is generally caused by the inconsistency between the belt and the groove. The large and small pulleys should be adjusted to be in the same plane. If the new belt is wrong, it should be replaced in time.
5. Abnormal sound
If the Roots blower makes abnormal noise, it should be caused by rotor collision and friction, bearing damage, and gear meshing problems, which can be repaired and solved according to Several Keys to Roots Blower Maintenance.
6. Vibration elimination
The vibration of Roots blower may come from the looseness of foundation and fasteners, and the fastening shall be checked. If the vibration comes from bearings, rotors and gears, please refer to Several Keys to Roots Blower Maintenance.
7. High temperature of bearing and gearbox
Such problems are mostly caused by poor lubrication, and the lubricating oil should be replaced in time. The heating caused by other reasons can also be solved by referring to the maintenance method. At the same time, equipment sanitation shall be cleaned and ventilation shall be strengthened to create conditions for equipment heat dissipation.
