What are the main factors contributing to excessive power consumption of the water pump?

The term "pump" is not unfamiliar to us. It is used in many industries and is indispensable in our daily lives. So, what are the factors that cause excessive power consumption of pumps? Our Xucheng Pump Industry editor will answer this for you.
I remember when there was no running water in our houses, every household had a well. But for irrigation of farmland, pumps were needed. A large amount of water flowed into the farmland, and children played in it. At that time, I thought the pump was a magical thing - so small yet it could moisten a large area of farmland. Now, pumps are used more widely. They are needed in water supply plants, hydropower stations, thermal power stations, and some factories. With more applications, there are also more malfunctions. What are the reasons for the excessive power consumption of the pumps and the resulting malfunctions?
【The factors causing excessive power consumption of the pump】
(1) The pump speed is too high;
(2) The specific gravity of the transported liquid exceeds the original design value;
(3) The liquid being transported has a high viscosity;
(4) The size of the pump impeller is too large;
(5) The resistance of the pipeline system exceeds or falls short of the predetermined value.
(6) The pump's head is too low and the flow rate is too high.
(7) There is friction between the rotor parts and the stator parts.
(8) Bearing wear or damage;
(9) The pressure exerted by the mechanical seal on the sealing seat is too high;
(10) The outlet pipeline has ruptured;
(11) The pump shaft of the water pump is bent.
(12) Uneven thermal expansion of different parts within the pump
(13) The dynamometer is inaccurate.
(14) The pump balance device is not functioning.
The above 14 points are the causes of excessive power consumption of the water pump. Of course, we hope that no faults will occur during the daily use of the water pump. These sorted-out fault causes are the basis for conducting a thorough investigation and quickly resolving the problems in case of faults. We hope that this will be helpful for your daily use of the water pump. Moreover, "prevention is more useful than cure". Regular maintenance and upkeep are good ways to reduce the occurrence of faults.
