Structure Instruction
XBD-D type horizontal multi-stage fire pump for the horizontal single suction multi-stage centrifugal pump, the suction inlet for the horizontal direction, the outlet for the vertical upward arrangement. The pump is composed of pump body parts and rotor parts. The pump body is composed of inlet section, middle section, guide vane, outlet section, tail cover and bearing body and other components, and the rotor parts are composed of stainless steel shaft, copper alloy impeller, balance plate and shaft sleeve. Both ends of the rotor are supported on grease-lubricated rolling bearings. The joint surface of the inlet section, the middle section and the outlet section is sealed by tightening with paper pad. In order to prevent water from leaking out of the shaft from both ends, a packing seal is provided, or a mechanical seal can be used. At the same time, a rubber water retaining ring and an O-type rubber sealing ring are arranged on the shaft to prevent water entering the bearing cavity. In order to prevent the wear of the middle section and guide vane, the impeller sealing ring and guide vane sleeve and other vulnerable parts are provided. When these parts are worn to a certain extent, they can be replaced.
