The reasons and solutions for the stuck Roots blower are as follows:
1、 Reason for jamming
1. Foreign object jamming: Large particles enter the fan chamber, blocking the gaps between various parts and causing the Roots blower to fail to rotate.
2. Impeller damage: The impellers interlock with each other, causing the impellers to not rotate and the fan to get stuck.
3. Gear damage: The gear meshing area is too large, and the meshing force is too strong, causing the gear to be unable to rotate and resulting in the fan getting stuck.
4. Bearing damage: Bearing damage on Roots blower can cause changes in the clearance between impellers, casings, and wall panels, resulting in impeller friction and preventing the fan from rotating.
5. Rusting and jamming: If the Roots blower is idle for a long time, rusting may occur, and the impeller may rust together with the wall panel or casing, or the rust may fall off in large areas, resulting in jamming between the impellers.
6. Motor damage: The Roots blower has a motor malfunction, which naturally results in the inability to rotate.
7. Excessive system load: The system load connected to the fan exceeds its design range, causing the fan to overload and potentially leading to jamming.
8. Component deformation: Prolonged use or external force can cause deformation of the rotor or housing, resulting in insufficient clearance and causing friction and jamming.
2、 Solution method
1. Immediately stop the operation of the fan: When a stuck fault is detected, the primary task is to immediately turn off the power and stop the operation of the fan to prevent further damage to the equipment or accidents.
2. Check and clean up foreign objects: Open the fan casing, check if the impeller and rotor are stuck, and if there are any foreign objects blocking. If present, appropriate tools and personal protective equipment should be used to clean it thoroughly.
3. Replace damaged components: If components such as impellers, rotors, gears, or bearings are damaged, they should be replaced with new components in a timely manner.
4. Rust removal treatment: For cases where rust is stuck, methods such as soaking in kerosene or washing with gasoline can be used to clean the rust and adjust the gap.
5. Check the motor: Confirm whether the motor is in good working condition, and repair or replace it promptly if there are any abnormalities.
6. Adjust system load: If the system load is too large, adjust the system load or add additional fans to share the load.
7. Regular preventive maintenance: In order to avoid the occurrence of stuck faults in Roots blowers, regular preventive maintenance and inspection should be carried out, including cleaning the inside of the blower, checking the wear of bearings, adjusting the fit size between the shaft and bearings, etc.
8. Contact professional maintenance personnel: If the above methods cannot solve the stuck fault of the Roots blower, it is recommended to contact professional maintenance personnel or manufacturer technicians for diagnosis and repair.
