Centrifugal pumps are extensively applied in different industries for liquid conveying. Their usage, however, like all mechanical equipment may have complications periodically.
Cavitation is the formation and collapse of vapor bubbles inside the pump due to a drop-in pressure of the fluid below its vapor pressure. This can cause noise, vibration, and damage to the pump parts.
Raise suction pressure by installing a cavitation-resistant impeller or reducing fluid velocity. Additionally, ensure proper priming and no air leaks on the suction line.
Low flow rate delivery by the pump may be caused by blockage at the suction line, worn impeller or wrong speed of the pump.
Check for blockages in the suction line, inspect and clean the impeller, adjust as necessary and make sure that there is good alignment between piping system and pumps.
Leaks occur either through shaft seals, casing joints or gaskets resulting in lower efficiency as well as safety hazards.
Inspect damaged seals, rings or gaskets before replacing them. Ensure proper tightening of casing joints as well as aligning them. For you upgrade to mechanical seals will enable your machine function more effectively.
Misalignment among other causes such as worn bearings, cavitation or resonance within a system could be responsible for too much vibration
Correct any misalignment between pump and motor; change out worn bearings; address cavitations issues then install vibration monitoring systems to detect early signs of trouble
Overheating can come about because of excessive friction inadequate cooling or incorrect lubrication process.
Properly lubricate bearings, moving parts etc., provide better cooling through suitable flow of fluid for external cooling devices while also maintaining operating temperatures at right levels.
The performance capacity of the pumping system can be compromised in the event of impeller wear.
Conduct regular inspections on impellers for indications of erosion, damage or even wearing and replace them when necessary. You may also consider using wear-resistant materials with longer service life.
Air leaks, poor priming, design inadequacy of suction line is some causes of suction problems.
Check for air leaks in the suction line and seal off any you find. Prime your pump properly before it starts working and ensure the suction is designed to minimize air entrapment and maximize flow rates.
Regular maintenance such as inspection, lubrication and replacement of worn out parts should be done to prevent such common issues on centrifugal pumps. Also consult pump manufacturers or experienced technicians to assist in trouble shooting these spe
