Single stage multi-suction pump
The XBD-W single-suction multi-stage sectional fire pump consists of two parts: the motor and the pump. The motor is a Y-type three-phase asynchronous motor. The fire pump and the motor are connected by a coupling. The whole is a rigid connection, and no correction is needed for use. The fire pump consists of a stator part and a rotor part. The stator part of the fire pump is composed of the inlet section, the middle section, the guide vane, the outlet section, and the stuffing body. In order to prevent the stator from being worn, the stator is equipped with a sealing ring, a balance sleeve, etc., and can be replaced with spare parts after wear. The rotor part has a shaft, a middle wheel, a balance drum and the like. The lower end of the rotor is a water-lubricated bearing, and the upper part is an angular contact ball bearing. The axial force of the pump is mostly carried by the balance drum, and the remaining small part of the residual shaft is subjected to the angular contact force by the angular contact ball bearing. The paper mat of the water inlet section, the middle section and the water outlet section is sealed by tensioning, and the user can select according to the needs.
