Problems solved by technology

[0002] The solid-liquid two-phase flow horizontal centrifugal pump used in China for conveying potatoes and other materials has the advantages of high efficiency, energy saving, corrosion resistance, long service life and high-concentration hydraulic transportation, but the corrosion resistance of the metal is poor, and the flow channel Small, easy to adhere to crystals and sediment, block the flow channel, reduce the operating efficiency of the pump, fail to reach the design parameters, and may damage the pump body in severe cases
However, the existing plastic pumps can only be used to transport clear water, and the scope of adaptation is narrow.
