Public transportation systems, including subway stations and railway terminals, are complex environments with high volumes of passengers and potential fire hazards from electrical equipment, flammable materials, and mechanical systems. Fire pumps are vital in these settings for delivering the water or suppression agents necessary to extinguish fires in tunnels, platforms, and adjacent facilities. Jockey pumps ensure constant pressure in the system, so fire suppression mechanisms like sprinklers, hydrants, and standpipes are always prepared to respond. Given the confined and underground nature of many transportation hubs, fire protection systems must be capable of addressing fires in tight, poorly ventilated spaces while facilitating the safe evacuation of passengers. The pumps also need to support fire hose connections for firefighters, who might need to cover long distances within tunnels or elevated railways. Regular inspections and emergency drills are essential to ensure that fire pumps are fully operational and integrated with ventilation and evacuation systems, providing a coordinated response to fire emergencies in these high-risk, densely populated environments.

First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
1. Centrifugal pump

Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
2. Impeller
The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

3. Cavitation

Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.
