1. The replacement of the pump material due to excessive loss of operation of traditional material pump, improve the pump efficiency pump replacement material used in western countries, including the United States the Simms composite effective pump. The utility model has the advantages of strong corrosion resistance to sea water and acid alkali medium, and is a structural composite material, which is completely processed by a numerical control machine tool. Graphite phenolic resin with unique fiber reinforced composite two-way or three to interweave together and to obtain high strength and elasticity, the fiber is continuously mixed; using Simms phenolic epoxy resin hybrid thermosetting resin matrix, the resin exhibits excellent mechanical properties and good chemical resistance; himst is graphite fiber, continuous woven glass fiber and synthetic fiber, fiber continuous, three-dimensional braiding, high strength suitable for applications such as pump impeller, to significantly improve the efficiency of the pump is increased.
2. The pump in different flow and import and export pressure, the efficiency is changed, the General Factory instructions have a working curve. The pump efficiency should be stable under fixed conditions. However, when the pump is lower than the rated flow, increase the frequency converter can reduce the power consumption, improve efficiency. Because the process of adjusting flow, the general is to reduce the export flow area, through the throttling effect, increase the export of water resistance, reduce the throttle flow, there will be irreversible loss; the inverter is to change the motor speed, reduce the water flow, water outlet resistance changed little. The polymer composite material in pump work, the pump by flowing water and its impact on the flow and the friction surface of water pump impeller and the pump itself viscosity, the energy consumption is mainly used for resistance to flow friction and eddy current resistance of water surface. The energy consumed by water in the process of flow (head loss) is used to overcome the internal friction and the friction between water and equipment. If the pump, impeller surface smooth (this surface is called hydraulic smooth surface) surface resistance is small, the energy consumption is small.
3. In the pump flow surface of impeller and spraying polymer composite materials, the formation of the hydraulic smooth surface on the surface of ultra smooth surface coating surface finish is after 20 times after polishing stainless steel, this extremely smooth surface reduces stratification within the pump fluid, thereby reducing the pump internal turbulent flow, reduce the pump volume the loss and hydraulic loss, reduces the power consumption. The aim of reducing the resistance loss of water flow is to improve the hydraulic efficiency of the pump, and to a certain extent, the mechanical efficiency and volumetric efficiency can also be improved. The molecular structure of the coating is compact, can be isolated from the air, water and other media and pump impeller base metal contact, to minimize the electrochemical corrosion and corrosion. In addition, the polymer composite material is a polymer, chemical corrosion resistance, can improve the corrosion resistance of the pump, can greatly enhance the pump resistance to erosion and corrosion resistance.
