Horizontal multistage fresh water pump is a new series of multistage segmented centrifugal pumps improved on the basis of DA type pumps. The stator part of the pump is mainly composed of front section, middle section, rear section, guide wing, tail cover and bearing body, which are connected by screw. The rotor part is mainly composed of several impellers mounted on the shaft (depending on the required head) and a balance disc for balancing the axial force. The entire rotor section is supported at both ends on single-row radial roller bearings lubricated with grease. Pumps with a diameter of more than 200mm adopt babb alloy sliding bearings. The static joint surface between the front, rear and middle sections of the horizontal multistage fresh water pump is sealed with paper cushion. The sealing of the rotating part between the stages of the pump is achieved by the sealing ring in front of the impeller and the small gap between the guide wing sleeve and the front section, the middle section and the guide wing. In order to prevent water from entering the bearing, the O-ring and the water retaining ring are installed. Both ends of the pump's working chamber are sealed with soft packing or mechanical seals to prevent air from entering and a large amount of liquid from leaking out. The stuffing box is composed of water inlet section, tail cover, packing gland, packing ring and packing. A small amount of liquid with a certain pressure acts as a liquid seal through the filling chamber. The direction of rotation of the pump is clockwise as viewed from the direction of the motor. Horizontal multi-stage fresh water pump production, more applications, the use is for the transport of water and physical and chemical properties similar to water liquid. It is suitable for mine drainage, urban and factory water supply. The technical specifications of horizontal multistage fresh water pump are more than one in multistage centrifugal pumps, for example, flow rate: 3. 75 -1100 m3/h, lift: 52. 5~1870m, with power: 5.5 ~ 2300kW.
