        Efficiency in a pump Analysis and Promotion Scheme

        In a pump efficiency reasons for the decline
        1, due to water erosion, water pump impeller and the inner wall of the flow path through the water became rough, the friction coefficient of the pump flow path increases, plus Sheung Shui in the pump flow rate greatly increased head loss. Hydraulic efficiency.
        2, since the drugs before dosing pump or water quality and other reasons, so that the pump housing severe fouling or corrosion. Severe fouling pump housing can increase the casing wall thickness of about 2ram, dirt and water pump wall to form tumors, so that the pump volume reduced, reducing the amount of pumping, and the flow path coarse, increase head loss. Customer product efficiency and hydraulic efficiency is reduced.
        3, casting defects caused due process pumps, cavitation, erosion, corrosion and chemical attack and other causes produce the pump flow passage holes or cracks, resulting in water flow caused by vortices of energy loss. Hydraulic efficiency.
        4, the surface of the impeller cavitation. Due to the dorsal surface of the blade run-time negative pressure, when the pressure Pk5, volume loss and mechanical loss. Since the pump using a long time, and resistance to mechanical wear and tear resulting leakage increases, the volumetric efficiency and mechanical efficiency. For these reasons, the pump performance deteriorates. Operating efficiency is reduced by 2 to 5%, the pump can be severely reduced by more than 10% efficiency.
        Enhance the efficiency of the pump in the open
        1, the use of polymer composites
        In pump operation, the pump flow of water is affected with the runner and the pump impeller surface friction and viscosity of the water itself, the energy consumed by the pump is mainly used for frictional resistance to flow and eddy-current resistance of the water surface. Energy (head loss) of water consumed in the flow process is used to overcome friction and friction within the water and equipment interface. If the pump impeller smooth surface (this surface is called hydraulic smooth surfaces) surface resistance is small. Energy consumption is small, the water pump and impeller flow surface coating polymer composite material on its surface forms a smooth surface water, ultra-smooth surface coating surface finish is 20 times through polished stainless steel, this very smooth surface reduction the stratified fluid pump, reducing pump internal turbulence, reducing the volume loss and loss of hydraulic pump, reducing the power consumption. To reduce the flow resistance loss purposes, thereby enhancing the efficiency of the hydraulic pump, and to a certain extent, can also improve mechanical efficiency and volumetric efficiency. Dense molecular structure of the coating can be isolated from contact with the air, water and other media and the pump impeller base material to minimize corrosion and electrochemical corrosion. Furthermore, the nature of the polymer composite material is a polymer having chemical resistance, corrosion resistance can be improved pump, the pump can greatly enhance erosion resistance and corrosion resistance.
        2, using a new sealing technology
        Pump part of energy loss during operation, including mechanical wear volume loss and water loss, mechanical loss refers to the water pump seal friction bushings, bearing friction, friction with the liquid surface of the impeller. Using Blu-Goo Super pump lubricant to reduce friction sealing sleeve, bearing friction, so as to improve pump efficiency, energy saving purposes. Which is a special inert material for a variety of purposes, mainly for reducing inter-metal contact. As a thread sealing compound, the material between the external and internal threads to form a contact surface that protects joints from impact of friction and wear, and can withstand 1407 kg / cm², even wear, corrosion or machine error processing flank. The product is also an excellent gearbox additive to a film can be formed on the inner member, thereby reducing friction and gear noise and leakage. It also significantly reduces torque stress, pressure to meet the power requirements can be used as a filler gasket surfaces or supplemented by a seal to prevent fluid leakage. It can be applied at a temperature of 316 ℃.
