XBD-D multi-stage fire-fighting centrifugal pump
D-type multi-stage fire-fighting centrifugal pumps are used in fire-fighting systems, factories and mines, high-rise buildings, heating, boiler water circulation, air-conditioning and refrigeration, and supporting equipment, etc.
Product introduction:
XBD-D horizontal single-suction multi-stage segmented fire pump is a newly developed series of energy-saving products. It has significant advantages such as high efficiency, low operating noise, good anti-cavitation performance, reasonable structure and long service life. For conveying clean water without solid particles and physical and chemical properties
The use of liquid similar to water is mainly used for pressurized water supply in fire fighting systems, and can also be used for water supply and drainage in factories and mines, pressurized water supply for high-rise buildings, long-distance water supply, heating, bathroom, boiler heating and cooling water cycle pressurization, air conditioning and refrigeration system water supply and Equipment matching and other occasions.
Technical Parameters:
Flow rate: 5-45L/S;
Pressure: 0.18-2.61Mpa;
Power: 2.2-180KW;
Speed: 1450r/min;
Caliber: φ50-φ150;

product advantages:
1. The pump has compact structure, small size, beautiful appearance, small floor space, and save construction cost;
2. The rotor parts of the pump are supported by rolling bearings at both ends, so the pump runs smoothly;
3. The inlet of the pump is horizontal, and the outlet is arranged vertically upwards, simplifying the pipeline;
Features:
1. This type of pump has a single-stage multi-stage segmental structure. Its suction port is horizontal and its discharge port is arranged vertically upwards. It is equipped with calibers of 50, 75, 100, 125, 150, etc. according to the requirements of flow and head. Choose pumps of different product diameters and stages to be satisfied;
2. This type of pump is mainly composed of water inlet section, middle section, guide vane, impeller, water outlet section, bearing body parts, sealing parts, etc., and its structure design is reasonable;
3. The rotor parts of the pump are composed of medium carbon steel shaft, cast iron impeller, balance disc and shaft sleeve, etc. Both ends of the rotor are supported on dry oil lubricated rolling bearings. Due to the dynamic and static balance of the impeller and the hydraulic balance of the balance disc, the pump It runs very smoothly, with low noise,
The vibration is small.
4. The joint surface of the water inlet section, the middle section and the water outlet section are sealed with paper pads by tightening bolts. In order to prevent the liquid from leaking from the main shafts at both ends, a soft packing shaft seal is installed, and a rubber water retaining ring is installed on the shaft. O-shaped rubber sealing ring, which enters the shaft sleeve cavity for waterproof;
5. In order to prevent wear of the middle section and guide vanes, vulnerable parts such as impeller seal ring and guide vane sleeve are specially set. When the gap between the impeller and these vulnerable parts exceeds the specified value, they should be replaced;
6. The pump and the motor are installed on a common cast iron base at the same time, and the torque is transmitted through the elastic coupling.
