As more and more people pay attention to the centrifugal pump, we can find that the inlet and the outlet of the double suction pump are both below the axis of the pump, and the horizontal direction is perpendicular to the axis. The pump casing is open , No need to dismantle the inlet water, exhaust pipe and motor from the coupling to the direction of the pump, the pump is counterclockwise rotation. The next main analysis of double suction pump working principle. Double-side inlet pump double suction pump working principle and structure Impeller after static balance verification, with the sleeve and the sleeve nut on both sides of its axial position can be adjusted by the sleeve nut, the impeller axial force Balanced with the symmetrical arrangement of its blades, some of the remaining axial forces may be supported on the coaxial end bearings. The pump shaft is supported by two single row radial ball bearings mounted on the bearing body at both ends of the pump body and lubricated with grease. Double suction seal ring to reduce the pump water pressure water chamber leakage back to the suction chamber. The main structure of the double suction pump: pump body, pump cover, impeller, shaft, double suction sealing ring, sleeve, bearings and so on. In addition to the shaft material for high-quality carbon steel, the rest mostly made of cast iron. The pump body and the pump cover form the working chamber of the impeller. The inlet and outlet water flanges are provided with tube screw holes for installing the vacuum gauge and the pressure gauge, and the tube screw holes for discharging water are provided under the water flanges. The pump is driven directly by the motor through the coupling. Shaft seal for the soft packing, in order to cool the lubrication seal chamber and prevent air leakage pump, there is a water seal between the packing, pump a small amount of high-pressure water flow through the filling pipe from the filling chamber sealing effect. Through the study of its working principle, we can find that the working principle of the double suction pump is on the other hand shows the working principle of the centrifugal pump in more detail. As the use scope of the double suction pump gradually increases, more and more people pay attention to the research The working principle of the product development and improvement has a very important role. A product is not only its own value, more likely to represent the direction of the development of the entire product, just as the barrel principle, only by all aspects of development, the rapid development of the entire industry. The same is true for double suction pumps. Related Articles: Single-side water pump single suction pump working principle and structure diagram Volute pump working principle and structure
