1. Adopt polymer composite materials

During the working process of the pump, the water flowing in the pump is affected by the friction between it and the surface of the runner and the pump impeller, as well as the viscosity of the water itself. The energy consumed by the pump is mainly used to resist the flow friction and eddy current resistance of the water surface. The energy (head loss) consumed by water in the flow process is used to overcome the internal friction and the friction between water and equipment interface. If the surface of pump and impeller is smooth (this surface is called hydraulic smooth surface), the surface resistance is small. The energy consumption is small. Polymer composite materials are sprayed on the overflow surface and impeller of the pump to form a hydraulically smooth surface. The surface finish of the super smooth surface coating is 20 times that of the polished stainless steel. This extremely smooth surface reduces the stratification of the fluid in the pump, thereby reducing the turbulence in the pump, reducing the volume loss and hydraulic loss in the pump, and reducing the power consumption. The purpose of reducing the flow resistance loss is achieved, so as to improve the hydraulic efficiency of the pump. At the same time, the mechanical efficiency and volumetric efficiency can be improved to a certain extent. The density of the coating molecular structure can isolate the contact between air, water and other media and the base metal of the pump impeller, and minimize electrochemical corrosion and corrosion. In addition, the polymer composite material is essentially a polymer with chemical corrosion resistance, which can improve the corrosion resistance of the pump and greatly enhance the ability of the pump to resist erosion and corrosion.

2. New sealing technology

There is a part of energy loss in the working process of the pump, including mechanical wear, volume loss and hydraulic loss. Mechanical loss refers to the shaft sleeve seal friction, bearing friction, impeller surface and liquid friction of the pump. Blu Goo super lubricant is used to reduce the seal friction and bearing friction of the water pump shaft sleeve, so as to improve the efficiency of the water pump, save energy and reduce consumption. It is a special inert material with multiple uses, mainly used to reduce the contact between metals. As a thread sealing compound, the material forms a contact surface between the external thread and the internal thread, which can protect the joint from friction and wear. At the same time, it can withstand a pressure of 1407 kg/cm2, even the worn, corroded or wrongly machined thread surface. This product is also an excellent gearbox additive, which can form a film on the internal parts to reduce friction, gear noise and leakage. It also significantly reduces the torque stress to meet the requirements of dynamic pressure reduction. It can be used for gasket face or as a filler supplement to prevent fluid leakage through sealing. It can be used at 316 ℃.
