What is the reason for the decrease in exhaust pressure of Roots blower
The decrease in exhaust pressure of Roots blower may be caused by various reasons, and the following are some common reasons for analysis:
1. Selection error:
If the selection of Roots blower does not meet the actual needs, such as selecting too small, its output air volume may be insufficient, resulting in the exhaust pressure not meeting the design requirements.
2. Loose or slipping belt:
Roots blowers typically use belt drives, and if the belt becomes loose or slips, it can cause a decrease in fan speed, which in turn affects exhaust pressure.
3. Motor issue:
Motor damage or incorrect motor wiring (such as reverse rotation) may also cause a decrease in exhaust pressure of the Roots blower. Motor damage may manifest as a decrease in power or inability to operate normally, while incorrect wiring may cause the fan to reverse, turning the exhaust outlet into an intake outlet.
4. Import pipeline issues:
Blockage, deformation or damage of the inlet pipeline can affect the intake volume of the fan, thereby affecting the exhaust pressure. In addition, blockage or deformation of imported dampers may also lead to similar problems.
5. Impeller issue:
The accumulation of dust and skin on the impeller or improper clearance between the impellers (such as excessive clearance) can reduce the efficiency of the fan, resulting in a decrease in exhaust pressure.
6. Sealing issue:
If the sealing between the components of the Roots blower is not sufficient, it will cause gas leakage, thereby reducing the exhaust pressure.
7. Wear and tear after prolonged operation:
After prolonged operation, the performance of various components of the Roots blower may decrease due to wear and tear, thereby affecting the exhaust pressure.
The following measures can be taken to investigate and handle the above reasons:
1. Check if the selection of Roots blower meets actual needs, and if necessary, replace it with a suitable blower model.
2. Check if the belt is loose or slipping, and if necessary, adjust the belt tension or replace it with a new belt.
3. Check if the motor is damaged or if the wiring is correct. If necessary, replace the motor or rewire it.
4. Clean the inlet pipes and dampers to ensure they are unobstructed.
5. Check for dust and skin buildup on the surface of the impeller. If necessary, clean the impeller and ensure its surface is smooth. At the same time, check if the impeller clearance is appropriate, and adjust the clearance if necessary.
6. Check whether the sealing between each component is good, and if necessary, replace the sealing components or strengthen the sealing measures.
7. Regularly maintain and upkeep the Roots blower to extend its service life and maintain its stable performance.
If the above measures cannot solve the problem, it is recommended to contact the manufacturer or personnel for repair and debugging.
