CHINA FACTORY XBD-HL VERTICAL FIRE-FIGHTING CONSTANT PRESSURE TANGENT PUMP. XBD-HL SERIES OF FIRE FIGHTING PUMP MANUFACTURERS, FACTORY, SUPPLIERS FROM CHINA

The fire constant pressure tangent pump has the characteristics of variable flow and voltage regulation, that is, in the full flow range, the pressure change is not large, and when the pump changes from zero flow to the required large flow range, the pressure change is within the range of 5%, and the small There is no overpressure at flow or zero flow, thus avoiding the phenomenon that the ordinary centrifugal pump is overpressured at medium and small flow and cannot supply water at large flow at the fire scene. 

 

Water supply for industrial and civil building fire-fighting systems (fire hydrant fire-extinguishing systems, automatic sprinkler systems and water mist fire-extinguishing systems). Fire-fighting and living (production) shared water supply systems and construction, municipal, industrial and mining, boiler water supply and other occasions.

 

Speed: 1450r/min, 2900r/min;

Medium temperature: ≤80 ℃ clean water Rinsing;

Flow range: 0～80L/s;

Pressure range: 0.3～2.0Mpa;

Rotation direction: The pump rotates clockwise when viewed from the motor end.

 

1. The fire flow is relatively regular. The fire hydrant water supply system is incremented by 5L/s. The automatic sprinkler system increases the flow value corresponding to the light, medium, and severe hazard levels.

2. The fire pump is used to ensure the water volume and water pressure of the fire water, which involves personal safety and property protection and must operate reliably. The pump body is required to have a reasonable structure, appropriate material and high reliability.

3. The fire pump water supply generally adopts the method of directly supplying water to the fire hydrants and sprinklers of the fire extinguishing facilities by the water pump. In the initial fire extinguishing or self-checking operation, the water supply is small flow, and the water supply is designed according to the design flow in the fire development stage. When the flow rate-lift curve of the pump is steep, it is easy to generate overpressure during small flow operation, and corresponding technical measures should be taken for this.

4. The fire pump is used for fire extinguishing, and it is required to be fast and timely. The corresponding requirements of the fire pump are short water diversion time and good start-up performance.
