Description

Product features

  1. Firstly, determine the boundary conditions of fluid flowing in different blade runners and flow passage geometric parameters of the impeller inlet and the outlet by the design method of one-dimensional flow, and then, make joint optimization calculations on geometric parameters of flow passage and variable conditions by means of the three-dimensional flow method, which not only ensures the accurate design parameters and the high efficiency, but also avoids the disadvantages of poor predictability and accuracy of flowing of the flow passage when designing the high specific speed pump by means of one-dimensional flow, ensuring the consistency of design and operating conditions. The pump operating efficiency is as high as 88-90%.
  2. Simplify the structure by shortening for the axial length to about 5metres, so that the shaft and seal is simple and not easy to leak which is safe and reliable.
  3. Being removed the traditional shaft sleeve protection process design, the outer surface of shaft (including surface of impeller) is painted with high strength wear-resistant materials, so as to simplify the structure and improve the reliability.
  4. The drive has double speed, which achieves the flexible adjustment of the pump with the change of season and main engine’s loads.
  5. The application is the circulation system of power plant.
