XBD-D multistage fire fighting diesel engine centrifugal water pump

XBD-D multistage fire fighting centrifugal pump -- Product Introduction
XBD-D horizontal single suction multistage segmented fire pump is the latest energy-saving series product developed and produced. The utility model has the advantages of high efficiency, low operating noise, good cavitation resistance, reasonable structure and long service life. For conveying clean water without solid particles and its physical and chemical properties
Liquid similar to water is mainly used for pressurization and water supply of fire protection system, water supply and drainage of factories and mines, pressurization and water supply of high-rise buildings, long-distance water supply, heating, bathroom, circulating pressurization of boiler cold and warm water, water supply of air conditioning and refrigeration system and equipment matching.
The performance and technical conditions of xbd-d series fire pumps produced by our factory meet the requirements of gb6245-1998 fire pump performance requirements and test methods newly issued by the state, and the products have passed the test by the national fire equipment quality supervision and testing center.

XBD-D multistage fire centrifugal pump -- product advantages
1. The pump has the advantages of compact structure, small volume, beautiful appearance, small floor area and saving construction cost;
2. The rotor parts of the pump are supported by rolling bearings at both ends, and the pump operates stably;
3. The inlet of the pump is horizontal and the outlet is arranged vertically upward to simplify the pipeline;
XBD-D multistage fire fighting centrifugal pump -- product features
1. This type of pump is a single-stage multi-stage segmental structure. Its suction inlet is horizontal, and its discharge outlet is arranged vertically upward. It is equipped with diameters of 50, 75, 100, 125 and 150. Users can select pumps with different diameters and stages according to the needs of flow and head;
2. This type of pump is mainly composed of inlet section, middle section, guide vane, impeller, outlet section, bearing body parts, sealing parts, etc. its structural design is reasonable;
3. The rotor components of the pump are composed of medium carbon steel shaft, cast iron impeller, balance disc and shaft sleeve. Both ends of the rotor are supported on dry oil lubricated rolling bearings. Due to the excellent dynamic and static balance of the impeller and the hydraulic balance of the balance disc, the pump runs very smoothly with low noise
Low vibration.
4. The joint surfaces of the water inlet section, the middle section and the water outlet section are tightened with paper pads through tensioning bolts to achieve sealing. In order to prevent liquid leakage from the main shafts at both ends, soft packing shaft seals are set. At the same time, rubber water retaining rings and O-type rubber sealing rings are installed on the shaft to prevent water from entering the shaft sleeve cavity;
5. In order to prevent the wear of the middle section and guide vane, vulnerable parts such as impeller sealing ring and guide vane sleeve are specially designed. When the gap between the impeller and these vulnerable parts exceeds the specified value, they shall be replaced;
6. The pump and motor are installed on the common cast iron base at the same time, and its torque is transmitted through the elastic coupling.
