进口防爆型立式潜水泵哪家品牌好

进口防爆型立式潜水泵Product Description: The impeller comprises a front cover plate of the impeller, a rear cover plate of the impeller and several impeller blades. The front cover plate of the impeller and the rear cover plate of the impeller are disc-shaped structures, and the two are arranged in parallel; The impeller blade is clamped between the front cover plate of the impeller and the rear cover plate of the impeller, and the upper and lower end faces of the impeller blade are close to and fixedly connected with the lower end face of the front cover plate of the impeller and the upper end face of the rear cover plate of the impeller respectively; 进口防爆型立式潜水泵The center of the upper surface of the front cover plate of the impeller is provided with a first round table; The impeller blade is a circular arc sheet part; The center of the upper surface of the impeller rear cover plate is provided with a second round table, the center of the second round table is provided with an axial circular through hole, and the hole wall of the circular through hole is provided with a keyway for key connection with the motor drive shaft of the water pump; The surface of the second round table is covered with the hub boss. The beneficial effects are: reducing resistance and wear, adjustable impeller blades, improving the working efficiency of the pump and reducing the cost. characteristic: Two phase flow pump is a water pump designed and manufactured according to the two-phase flow theory, such as slurry pump.进口防爆型立式潜水泵 Now the slurry pump is studied. Slurry pumps are mostly used to transport two-phase fluids with suspended solids and high density. They are widely used in electric power, metallurgy, transportation, water conservancy and other industries. Because the solid-liquid slurry to be transported in actual use contains solid particles, the overflow parts of the slurry pump are easy to be worn, which not only reduces the reliability of the operation of the slurry pump, but also causes unnecessary losses to the production due to frequent maintenance. The abrasion damage of the overflow parts of the slurry pump deteriorates the performance of the pump, reduces the reliability and efficiency, increases the energy consumption, shortens the service life and sharply increases the maintenance cost. Therefore, the research on the wear of overflow parts of slurry pump is particularly important. Principle: Metal slurry pump 2 Metal plus rubber lined slurry pump 3 Metal plus ceramic lined slurry pump. Although the metal slurry pump has high strength, good rigidity and toughness, it has the problems of poor corrosion resistance and wear resistance, frequent replacement of overflow parts and high equipment maintenance cost; The slurry pump with metal and rubber lining has good deformation ability and resistance to chloride ion corrosion. However, it is also easy to hydrolyze and fall off, which affects the use of slurry pump; The slurry pump with metal and ceramic lining, especially the slurry pump with silicon carbide ceramic lining, has good hardness, high temperature resistance, corrosion resistance and wear resistance
