Pump Curve The first step toward troubleshooting the centrifugal pump is to look at the Pump Curve (Figure 1). This curve is published by the manufacturer to plot the … Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.

Solved problems on centrifugal pumps can help build knowledge and expertise in pump maintenance and troubleshooting.
Problems with Centrifugal Pump
There are several common problems that can occur with centrifugal pumps, including:
1. **Cavitation**: This occurs when vapor bubbles form in the pump due to low pressure, causing damage to the impeller and reducing pump efficiency.
2. **Low Flow Rate**: Issues such as clogged impellers, air leaks, or incorrect pump settings can result in a lower flow rate than desired.
3. **Overheating**: Excessive heat generation in the pump can lead to mechanical failure and reduced pump lifespan.
4. **Vibration and Noise**: Unusual vibrations or noises during pump operation may indicate misalignment, worn bearings, or other mechanical issues.
Troubleshooting Centrifugal Pump Problems
When faced with centrifugal pump problems, it is essential to follow a systematic troubleshooting process to identify and resolve the root cause of the issue. Here are some general steps to troubleshoot centrifugal pump problems:
1. **Check Suction and Discharge Lines**: Ensure that the suction and discharge lines are free from blockages or restrictions that could impede flow.
2. **Inspect Impeller and Wear Rings**: Examine the impeller and wear rings for signs of damage, wear, or erosion that could affect pump performance.
3. **Verify Pump Settings**: Check that the pump settings, such as speed, impeller size, and motor power, are correctly configured for the application.
4. **Monitor Operating Conditions**: Keep an eye on operating conditions such as temperature, pressure, and flow rate to detect any abnormalities.
5. **Perform Regular Maintenance**: Implement a preventive maintenance schedule to clean, lubricate, and inspect the pump components regularly.
Centrifugal Pump Not Taking Suction
If a centrifugal pump is not taking suction, it could be due to several reasons, including:
1. **Air Leaks**: Check for air leaks in the suction line or pump casing that could prevent proper suction.
2. **Clogged Strainer**: A clogged strainer can restrict flow into the pump, causing suction issues.
3. **Low Liquid Level**: Insufficient liquid level in the suction tank can prevent the pump from priming and taking suction.
Centrifugal Pump Problems and Solutions
To address centrifugal pump problems effectively, it is crucial to implement appropriate solutions based on the specific issue at hand. Some common solutions to centrifugal pump problems include:
1. **Cavitation**: Increase suction pressure, reduce pump speed, or install a larger impeller to mitigate cavitation issues.
2. **Low Flow Rate**: Clear any blockages in the suction line, adjust pump settings for higher flow, or replace worn impellers to improve flow rate.
3. **Overheating**: Improve cooling system efficiency, reduce pump speed, or install temperature sensors to prevent overheating.
Check the appearance and condition of the pump internal components. Check when the pump was last serviced. Check for any changes in pump noise or vibration. This will save …
