D - type pump single - suction multi - stage centrifugal pump structure and use
发布时间：2023-03-29 10:07:00 点击：
D type pump on the basis of DA type pump improved into a new series of single suction multistage type centrifugal pump, the stator part of the pump is mainly composed of front section, middle section, after section, guide wing, tail cover and bearing body and other parts of the screw connection. The rotor part is mainly composed of several impellers installed on the shaft (according to the required lift) and a balance plate used to balance the axial force. Both ends of the entire rotor section are supported on a single row of greased centripetal roller bearings.
More than 200mm diameter pump using babbitt alloy sliding bearing.The static joint surface between the front section, the back section and the middle section of the D type pump is sealed with paper pads. Between the levels of the pumpIn order to prevent water from entering the bearing, O-ring and water retaining ring are installed. The rotating part of the seal is by the impeller before the seal ring and the guide wing sleeve and the front section, themiddle section and the guide wing between the small gap to the pump with soft packing or mechanical seal at both ends of the studio, to prevent air entry and a lot of liquid seepage packing box by water section, tail cover, packing gland, packing ring and packing. A small amount of fluid with a certain pressure passes into the packing chamber to act as a liquid seal.
From the motor direction, the direction of rotation of the pump is clockwise. Type D multistage centrifugal pump production, many applications, is used to transport water and physical and chemical properties similar to water liquid. It is suitable for mine drainage, urban, factory water supply.Thetechnical specifications of type D pump are the most in the multi-stage centrifugal pump. For example, the flow rate is 3.75~1100m/h, the head is 52.5~1870m, and the power is 5.5~2300kW.
