centrifugal pump sample problems|solved problems on centrifugal pumps : store The document contains 20 problems related to centrifugal pumps. The problems cover topics such as calculating specific speed, total suction head, impeller diameter, pump work, horsepower required, number of stages, efficiency, … Screw pumps for power transmission systems are generally used only on submarines. Although low in efficiency and expensive, the screw pump is suitable for high pressures (3000 psi), and delivers fluid with little noise or pressure pulsation. Screw pumps are available in several different designs; however, they all operate in a similar manner.

Reduced Flow or Low Flow
One of the most common problems encountered with centrifugal pumps is reduced flow or low flow rate. This can be caused by a variety of factors, including clogged impellers, air leaks in the suction line, or worn-out pump components. To address this issue, follow these troubleshooting steps:
- Check the impeller for any debris or blockages that may be restricting flow.
- Inspect the suction line for air leaks and repair any leaks found.
- Replace worn-out pump components, such as impeller or casing, if necessary.
By addressing these issues, you can restore the pump's flow rate to its optimal level and ensure efficient operation.
Abnormal Noises
Another common problem with centrifugal pumps is the presence of abnormal noises during operation. These noises can indicate issues such as cavitation, loose components, or misalignment. To troubleshoot abnormal noises, follow these steps:
- Check for cavitation, which is caused by low pressure at the impeller inlet. Adjust the pump's operating conditions to prevent cavitation.
- Inspect for loose components or misalignment in the pump assembly. Tighten any loose components and realign the pump as needed.
By addressing these issues, you can eliminate abnormal noises and prevent potential damage to the pump.
Leaks
Leaks in a centrifugal pump can lead to loss of fluid, reduced efficiency, and potential safety hazards. Common causes of leaks include worn-out seals, gaskets, or O-rings. To fix leaks in a centrifugal pump, follow these steps:
- Inspect the seals, gaskets, and O-rings for wear and tear. Replace any damaged components with new ones.
- Ensure that all connections and fittings are properly tightened to prevent leaks.
By addressing leaks promptly, you can prevent further damage to the pump and ensure safe and efficient operation.
In conclusion, centrifugal pumps are essential equipment in various industries, and encountering problems with them is not uncommon. By following the troubleshooting steps outlined in this article, you can effectively diagnose and resolve common centrifugal pump issues, ensuring smooth operation and optimal performance.
