What are the main factors that affect the efficiency of centrifugal pumps? Below we will share with you the main factors that affect the efficiency of centrifugal pumps, hoping to be helpful to you!
1. The efficiency of the pump itself is the most fundamental influencing factor. Under the same working conditions, the efficiency of the pump may differ by more than 15%.
2. Before starting the centrifugal pump, the staff did not pay attention to the preparation work before starting the centrifugal pump. The basic operating rules of temperature pumps, disc pumps, and liquid filling pumps have not been fully implemented, often resulting in pump cavitation, high noise, vibration, and low pump efficiency.
3. Hydraulic losses include hydraulic friction and local resistance losses. After a certain operating cycle, the surface of the impeller and guide vanes will inevitably wear out, hydraulic losses will increase, and hydraulic efficiency will decrease.
4. The operating condition of a centrifugal pump is lower than the rated condition of the pump. Low pump efficiency and high energy consumption.
5. The centrifugal pump is in an idle state due to blockage of the filter cartridge and the inlet of the pipeline.
6. The volume loss of a pump, also known as leakage loss, includes three types of leakage losses: impeller sealing ring, interstage, and axial force balance mechanism. The level of volumetric efficiency is not only related to design and manufacturing, but also to later management. After a certain period of continuous operation of the pump, due to friction between various components, the gap increases and the volumetric efficiency decreases.
7. The efficiency of the motor remains basically unchanged during operation. Therefore, choosing a high-efficiency motor is crucial.
8. The impact of mechanical efficiency is mainly related to design and manufacturing quality. After selecting the pump, the impact on later management is relatively small.
