1. Pipeline centrifugal pump is used to transport clean water and other liquids with physical and chemical properties similar to clean water. It is applicable to industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden irrigation, pressurized fire fighting and supporting equipment.

2. Hot water circulating pumps (high temperature) are widely used in energy, metallurgy, chemical industry, textiles, paper, hotels and other boilers for high-temperature hot water pressurized circulating transmission and urban heating system circulating pumps. The ISWR service temperature is less than or equal to 120 ℃, and the WRG service temperature is less than or equal to 240 ℃.

3. Horizontal chemical pump, which is used to transport non solid particles, corrosive liquids with viscosity similar to water, is suitable for petroleum, chemical industry, metallurgy, power, paper making, food, pharmacy, synthetic fiber and other industries. The operating temperature is T: - 20 ℃ to 120 ℃.

4. Horizontal oil pump is used to transport gasoline, diesel oil, kerosene and other petroleum products, and the operating temperature T: 20 ℃ to 120 ℃.

Improve the efficiency of horizontal centrifugal pump

The energy saving and consumption reduction of centrifugal pump should be explored constantly under the condition of combining theory with practice, boldly applying new technologies and looking for more reasonable and economic energy saving measures.

During the working process of centrifugal pump, the flow of pump water affects the viscosity of the friction and flow channel pump impeller surface and water itself. The energy consumption of the pump is mainly used to resist the water friction surface flow and eddy current resistance. The energy consumed in the water flow (head loss) is used to overcome the internal friction and the friction between the water and the device.

If the surface of pump and impeller is smooth (this surface is called hydraulic smooth surface), the surface resistance is small and the energy consumption is small.
