Many people occasionally have some small problems on the machine when using Roots blower, which causes the fan to fail to operate normally. Customers without maintenance experience should not blindly adjust the machine. Today, I will take you to understand the hidden dangers of Roots blower.
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 there is any abnormal noise in roots blower, it should be caused by rotor collision and friction, bearing damage, and gear meshing problems. It can be repaired and solved according to the key maintenance methods of roots blower.
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 the key treatment of 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.
I believe that after reading the above contents, you should also have some understanding of the hidden dangers of Roots blower. I hope it will be helpful to you.
