In most industrial and commercial applications, fluid handling systems are largely dependent on the performance of suction pipes, foot valves, and strainers. The smooth and efficient running of pumps, mostly centrifugal pumps, depends on these three components. Being part of any mechanical system, however, they may face some problems that hamper their performance. Being able to diagnose and troubleshoot these common problems can help keep your systems running efficiently and avoid expensive downtime.
1. Suction Pipe Problems
1.1 Air Leaks
Problem: One of the most frequent suction pipe issues is air leaks. Air ingress into the suction line is quite dangerous because it causes cavitation, strongly damaging the pump and reducing efficiency.
Troubleshooting:
- Check Connections: Check all the joints and connections along the suction pipe. Ensure that the fittings are all tightly fastened and no gaps or visible cracks are there.
- Inspect the Pipe: Inspect the pipe for any damage or wear; any punctures or cracks should be repaired or replaced.
- Test the System: Test the system for leaks by conducting a pressure test on the suction line. This is done by closing the discharge valve and noting the drop in pressure.
1.2 Clogging
Problem: Most often, suction pipes of pumps block due to debris or sediment, considerably reducing the effective fluid flow through them and hence their performance.
Troubleshooting:
- Check for Blockages: Check for blockages inside the suction pipe. Clean the pipe properly to remove accumulated debris material.
- Regular Maintenance: Devise a periodic check for cleaning the suction pipe to avoid this problem in the future.
- Use a Strainer: A strainer at the suction inlet may be installed to catch debris before it enters the pipe and pump system.
2. Foot Valve Problems
2.1 Valve Leakage
Problem: Foot valves are installed on the end of a suction line to prevent backflow and maintain prime in the suction line. A leaking or faulty foot valve will allow the loss of prime and a subsequent loss in pump efficiency.
Troubleshooting:
- Inspect Valve: Check the valve for leakage or wear. Replace seals or components if damage is noted.
- Clean Valve: Debris or sediment may be blocking the foot valve, preventing proper operation. Clean the valve and ensure it opens freely without interference.
- Check Operation: Check the foot valve to make sure that it closes properly and will hold fluid in the suction line.
2.2 Valve Sticking
Problem: This can result in operational problems and even loss of suction due to sticking of the foot valve to the well, caused by debris or corrosion.
Troubleshooting:
- Check for Debris: Check for any debris or other obstructions on this valve that could result in sticking. The valve should be cleaned properly.
- Lubrication: Make sure the moving parts of the valve are lubricated enough so that they don’t stick.
- Replace if Necessary: If the valve is badly corroded or otherwise damaged, it may be necessary to replace it with a new one.
3. Problems with the Strainer
3.1 Clogging
Problem: Strainers are put in place to filter debris and thereby block entrance into the pump system. They can, over time, become clogged and really cut down their effectiveness.
Troubleshooting:
- Check for Clogging and Clean: The strainer should periodically be checked for clogging. Remove and clean the strainer to regain its proper filtering capability.
- Replace if Needed: Replace with a new strainer if it is damaged or has accumulated more debris than usual.
- Adjust Scheduled Maintenance: On observation of a large amount of debris in the system, the frequency of maintenance for strainer inspection and cleaning should be increased.
3.2 Incorrect Sizing
Problem: A strainer that is too small or too large for the system results in poor performance.
Troubleshooting:
- Check Size and Type: Ensure that it is of an appropriate size relative to the flow rate and fluid type in your system.
- Consult Manufacturer: Consult specifications given by the manufacturer or consult a professional regarding strainer sizing.
