Using polymer composite materials in the work process 600S75 pump double suction pump, the pump flow of water by the energy with the flow channel and pump impeller surface friction and viscosity affect the water itself, the pump is mainly used for the consumption of water surface resistance friction and eddy flow resistance. Energy (head loss) of water consumed in the flow process is used to overcome the friction and the internal friction of the water and the device interface. If the pump impeller smooth surface (this surface is called hydraulic smooth surface) surface resistance is small. Energy consumption is small, the water pump and impeller flow surface coating polymer composites 150S50 double suction pump to the surface to form a smooth surface water, ultra-smooth surface coating surface finish is polished stainless steel after 20 times, this very smooth surface reduces the stratified fluid pump, thereby reducing internal turbulence pump double suction pump, reducing the volume loss and hydraulic losses in the pump and reduce power consumption. To reduce flow resistance loss purposes, thereby improving the efficiency of the hydraulic pump, while a certain extent, also increase the mechanical efficiency and volumetric efficiency. Dense molecular structure of the coating, can be isolated from contact with the air, water and other media and base metal pump impeller, minimize galvanic corrosion and rust. Further, the nature of the polymer composite material is a polymer 900S23 double suction pump, having a chemical resistance, corrosion resistance can be improved pump, the pump can greatly enhance the resistance to erosion and corrosion resistance. Mechanical rotating unbalanced motor and pump parts quality, shoddy, poor quality of the installation, the axis of the asymmetric unit, runout exceeds the allowable value, the poor mechanical strength and stiffness of components, bearings and seals to wear and tear parts, as well as the critical speed of the pump appears natural frequency and resonance unit has been caused, will have a strong vibration and noise. 12SH-28 double suction pump, water pump Xin Cheng (certified), double suction pump provided by Hebei Xin-pump factory.
