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.

A multistage pump refers to a pump with two or more impellers, which can absorb and press water in multiple stages, so as to lift the water to a high position. The lift can be increased or decreased according to the needs of the pump impeller. The multistage pump can be equipped with a four-stage motor by increasing the number of impellers when the single-stage pump head needs to be equipped with a two-stage motor, which can improve the service life of the pump and reduce the noise of the unit.

The full name of diesel engine fire pump is engineering diesel engine fire pump set, which can be automatically charged, automatically started, and has the functions of automatic alarm and automatic preheating. The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

Designed for harsh environments, the outdoor fire pump system features waterproof, dustproof, and corrosion-resistant features, making it suitable for fire water supply in factories, docks, chemical plants, and remote buildings.
