Types of multistage centrifugal pumps are divided into: Self-balancing multi-stage pump, single suction multi-stage centrifugal pump, double inlet multi-stage centrifugal pump, double suction horizontal multistage centrifugal pump and multi-stage double-suction pump, each of which has its own unique advantages, in this article, multi-stage centrifugal pump manufacturer Changsha Zoomlian Pump industry will focus on introducing the product advantages of two Stage Split Case Pump designed and produced by our company, after reading this article, You will have a deeper understanding of the multi-stage medium-open double suction pump.
1、high efficiency and energy saving: the use of high efficiency hydraulic model and optimized flow channel, so that the hydraulic efficiency of two Stage Split Case Pump to achieve the best. Double inlet parallel flow channel structure, no balanced water leakage, sealing water leakage and volume loss caused by axial force balancing device, while no additional axial force balancing device such as balance drum, no axial channeling during operation 1.
2、large flow capacity: double suction pump is equivalent to two single suction impeller of the same diameter working at the same time, under the same impeller diameter flow can be doubled 2516. This structural design makes the double suction pump widely used in industrial scenarios requiring large flow rates.
3、easy maintenance: pump shell horizontal open, easy inspection and maintenance. The inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet water pipe. We should not underestimate this advantage. In long-term operation, convenient maintenance will be a very obvious advantage.
4、symmetrical structure, smooth operation: the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is stable. The optimal design of the double suction impeller reduces the axial force to a minimum, and has excellent hydraulic performance of the blade profile, and has been optimized18.
5、wide range of application: Suitable for industrial and urban water supply and drainage, agricultural drainage and irrigation, water and other liquids with physical and chemical properties similar to water, the temperature range of the transported liquid is wide, from -20 ° C to 80 ° C, widely used in water conservancy projects, especially in high-altitude areas of water diversion projects, often use single-suction multi-stage centrifugal pump and multi-stage double-suction pump combination. To achieve the purpose of large flow, high lift water transport.
6、good anti-cavitation performance: in the horizontal in the open double suction volute and impeller structure, so that the two Stage Split Case Pump anti-cavitation performance than the single suction multi-stage centrifugal pump has obvious advantages, which means that the pump can adapt to higher suction, the installation conditions have greater tolerance.
