Change the material of the pump. Due to the excessive running loss of the traditional material pump, some Western countries have used pump materials to improve the efficiency of the pump, and Himax composite materials have superior corrosion resistance to seawater and acid-alkaline media. It is a structural composite material. Completely machined by CNC machine tools, all composite materials are manufactured structurally. The unique graphite-based phenolic resin-reinforced composite fibers are bi- or tri-directionally intertwined and these reinforcement fibers are continuous for high strength and elasticity; the use of Hi-Mix-mixed novolac epoxy resin-mixed thermosetting resin matrix The resin exhibits excellent mechanical properties and good chemical resistance; Hilmst is a continuous woven graphite fiber, glass fiber and synthetic fiber, all continuous fiber, three-dimensional weaving, suitable for high strength such as pump impeller The application has a significant improvement in the efficiency of the pump.
The efficiency of the pump varies under different flow rates and inlet and outlet pressures. There are working curves in the general manufacturer's specifications. Pump efficiency should be stable under fixed conditions. However, when the pump is lower than the rated flow, increasing the frequency converter can reduce motor power consumption and increase efficiency. Because the process of adjusting the flow rate is generally to reduce the outlet flow area, through the throttling effect, increase the water outlet resistance, reduce the flow, throttling will have irreversible losses; and the inverter is to change the motor speed, reduce the flow of water, water Export resistance changed little.
In the process of pump operation using polymer composite materials, the water flowing in the pump is affected by the friction with the flow path and the surface of the pump impeller and the viscosity of the water itself. The energy consumed by the pump is mainly used to resist the flow friction on the water surface and Eddy current resistance. The energy consumed by the water during the flow (head loss) is used to overcome the internal friction and the friction between the water and the equipment interface. If the surface of the pump or impeller is smooth (this surface is called a hydro-smooth surface), the surface resistance is small and the energy consumption is small.
The polymer composite material is sprayed on the water flow face of the pump and the impeller to form a smooth and smooth surface. The surface finish of the ultra-smooth surface coating is 20 times that of polished stainless steel. This extremely smooth surface reduces the fluid in the pump. Stratification reduces the internal turbulence in the pump, reduces the volume loss and hydraulic loss in the pump, and reduces power consumption. To achieve the purpose of reducing the resistance loss of the water flow, thereby improving the hydraulic efficiency of the pump, and at the same time, it can also improve the mechanical efficiency and the volumetric efficiency to some extent. The denseness of the molecular structure of the coating can prevent the contact of air, water and other media with the base material of the pump impeller, and minimize electrochemical corrosion and corrosion. In addition, the polymer composite material is essentially a high-molecular polymer, has chemical resistance, can improve the corrosion resistance of the pump, and can greatly enhance the pump resistance to erosion and corrosion resistance.
