Product overview
XBD fire pump is divided into single suction single stage and single suction multi-stage sectional type. It is used for conveying clear water without solid particles and liquid with physical and chemical properties similar to water. It is mainly used for pressurized water supply of fire fighting system and water supply and drainage of factories and mines. The flow range of conveying liquid is 5 ~ 80L / s, the pressure range is 0.2 ~ 2.25mpa, the matching power range is 1.5 ~ 200kW, and the caliber range is φ 50 ~ φ 250mm.
main features
1. The fire pump has compact structure, small volume and beautiful appearance. Its horizontal structure determines that the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the operation stability and service life of the pump.
2. The suction and discharge of the fire pump are horizontal, which simplifies the connection of the pipeline.
3. The multi-stage fire pump can be installed in the same direction or 90 ° 180 ° and 270 ° different directions to meet different connection occasions.
4. The pressure of the fire pump can be increased or decreased according to the need and the outer diameter of the impeller can be cut to meet the requirement without changing the installation area, which is not available for other pumps.
5. The fire pump rotor has small winding, stable operation, small vibration, low noise and long service life.
Product use
XBD fire pump is mainly used for pressurized water supply of fire system pipeline. It can also be used in industrial city water supply and drainage, high-rise buildings pressurized water supply, long-distance water supply, heating, bathroom, boiler cooling and heating water cycle pressurized air conditioning refrigeration system water supply and equipment matching, etc., instead of the original is centrifugal pump.
Structure elucidation
Xbd-l vertical single-stage single suction stabilized pressure fire pump is composed of motor and pump. The pump and motor are coaxial. The pump structure includes pump body, impeller, pump cover, mechanical seal and other components. The inlet and outlet of the pump are on the same horizontal axis, and the caliber specifications are the same. It is very convenient to load and unload, and the floor area is small. The pump is equipped with a mounting base to facilitate the installation and increase the stability of the pump operation. The pump seal adopts mechanical seal, which has the characteristics of reliable seal and no leakage. The axial force of the pump is balanced by the impeller with a balance ring. The inlet and outlet flange of the pump is designed according to the pressure of 1.6Mpa, with convenient pipeline matching.
Xbd-l vertical single-stage single suction fire-fighting stabilized pressure pump is composed of two parts of motor. The motor is Y-type three-phase asynchronous motor. The pump and motor are connected by coupling, and the whole is rigid connection, so no correction is required when using. The pump is composed of stator part and rotor part. The stator part of the pump consists of water inlet section, middle section, guide vane, water outlet section, stuffing box and other parts. In order to prevent the stator from wearing, the stator is equipped with sealing ring, balance sleeve, etc., which can be replaced with spare parts after wearing. The rotor part consists of shaft and middle wheel. Balance drum and other components. The lower end of the rotor is water lubricated bearing and the upper part is angular contact ball bearing. Most of the axial force of the pump is borne by the balance drum, and the remaining small part of the residual axial downward force is borne by the angular contact ball bearing. The joint surface of the water inlet section, the middle section and the water outlet section is sealed with paper pad through tension, which can be selected by users according to their needs.
