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.

The small-flow, high-stability fire-fighting pressure-stabilizing pump is designed specifically for building fire protection engineering. It can continuously maintain the pressure of the fire protection pipeline network, avoid frequent starts of the main pump, and is suitable for sprinkler and fire hydrant systems, significantly improving the stability and reliability of the fire protection system.

The fire pump is actually a pump that needs to be used in fire protection. According to different classification methods, it can be divided into different types of pumps. With its characteristics of full sealing, no leakage and corrosion resistance, it is widely used in environmental protection, water treatment, fire protection and other departments to pump various liquids. The pump types of the system are similar, but the head and flow are different. The selection basis of the fire pump should be considered from five aspects according to the technological process and water supply and drainage requirements. Fire truck fire pumps are used in fire protection, water treatment, environmental protection and other departments to pump various liquids.

The lower the pumping head of the fire pump, the smaller the motor load. Under the misleading of this kind of misunderstanding, when purchasing a water pump, the head of the water pump is often selected to be very high. In fact, for centrifugal water pumps, when the pump model is determined, the power consumption is proportional to the actual flow of the pump. The flow rate of the water pump will decrease with the increase of the head, so the higher the head, the smaller the flow rate and the smaller the power consumption. Conversely, the lower the lift, the greater the flow and the greater the power consumption. Therefore, in order to prevent the motor from overloading, it is generally required that the actual pumping head of the pump should not be lower than 60% of the calibrated head.

Electric fire pumps are used in various water environments, not only to meet the general water supply but also to be a good helper for fire-fighting water. The electric fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The electric fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

Fire pumps can be installed in locations with limited space, but it’s important to follow space requirements outlined in the manufacturer’s specifications and local codes. Proper clearances around the pump ensure ventilation and accessibility for maintenance.
