Standard fire pumps are mainly used to transport water for fire fighting
Fire pump is one of the fire-fighting equipment, its function is mainly used to transport water or other fire-extinguishing liquid for fire-fighting. Pumping water with equipment such as fire pumps has a very high water delivery efficiency. There are many types of fire pumps, and the air pumping methods of different fire pumps are also different. Sprinklers, fire hydrants, and water cannons and window sprays commonly used in business have the same pump-starting principle, but the fire-fighting linkage principle is different.
1. 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 more reliably. It is required that the structure of the pump body is more reasonable, the material is more appropriate, and the reliability is higher.
2. The water supply of the fire pump generally adopts the method of directly supplying water to the fire extinguishing facilities (fire hydrant, sprinkler head) 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.
3. The fire pump is used for extinguishing fire, and it is required to be fast and timely. The corresponding requirement is that the fire pump has a shorter water diversion time than ordinary life pumps and better starting performance.
