What is the reason for the excessive current of the pump working motor?

Water pump is a general-purpose machine, which is widely used in various fields of national economic construction, such as petrochemical industry, mining, metallurgy, electric power, water conservancy, national defense, farmland irrigation and drainage, urban water supply and drainage, etc. Because ordinary water pumps are castings, they are generally delivered after simple polishing in the factory. The fluid surface of the pump is extremely rough, and the resistance of the fluid in the pump is too large, which will increase the shaft power of the pump and cause energy waste. In addition, due to the different operating environment of the pump, the over-flow parts of the pump, such as impeller and shell, will be damaged to varying degrees, such as cavitation, wear and chemical corrosion, and then the impeller will be damaged by grooves and honeycombs, which will affect the operating efficiency of the pump. Therefore, if we can improve and maintain the efficiency of the pump and reduce energy consumption, it will produce far-reaching social benefits.

Recommended patented technology-"high efficiency and energy saving coated pump" technology. In recent years, more than a thousand circulating pumps in many enterprises have been reformed, and the energy-saving effect is obvious. After transformation, the energy-saving rate of water pump is generally around 10%, and the energy-saving effect is obvious within three years. The technical principle is that liquid ceramic material, a patented product independently developed by our company, is brushed on the surface of pump casing and impeller after surface treatment. This material is a super-smooth polymer filled with ceramics, which has strong adhesion. After curing, a coating with high gloss and low friction coefficient can be obtained, and it is hydrophobic. In addition, the high elastic surface of polymer material itself can reduce or offset the impact of water flow and resist all kinds of acid and alkali corrosion. The embodiment of various performances can effectively reduce the energy consumption of pump equipment at this stage.
