In daily life, the use of pumps is widespread. They are essential for transporting liquids or increasing their pressure. Pumps transfer mechanical energy to the liquid, thereby boosting its energy level. They can handle not only pure liquids but also gas-liquid mixtures or fluids containing suspended solids. However, when using a pump, maintenance issues are inevitable. This article will discuss key considerations for pump maintenance.
First, avoid relying on "experience" alone. For instance, if a pump valve leaks, some people may try to fix it by filling the inlet pipe with dry soil before starting the pump, hoping that the soil will seal the valve. While this method might seem simple, it is actually unsafe. When the pump starts, the soil can be sucked into the pump, causing severe wear to the impeller, pump housing, and shaft, which significantly shortens the pump’s lifespan. The correct approach is to overhaul or replace the faulty bottom valve instead of trying temporary fixes.
Second, any faults should be addressed promptly. Do not allow the pump to continue operating while malfunctioning. For example, if the packing around the pump shaft is worn out, simply adding more packing is not a long-term solution. If left unchecked, the leakage can increase energy consumption and accelerate cavitation, which damages the impeller and reduces the pump's overall service life. Similarly, if the pump vibrates abnormally, it should be stopped immediately for inspection. Ignoring vibration could lead to serious issues like shaft bending or deformation, posing safety risks.
In addition to these points, proper maintenance during daily use is equally important. After each use, the pump should be cleaned regularly to prevent buildup. Bearings should be checked and kept clean to ensure smooth operation. Also, make sure that no debris enters the system, as it can cause blockages or damage internal components. Following these practices not only extends the pump’s life but also ensures safe and efficient performance. Regular attention to these details can prevent many common problems and save time and money in the long run.
