Fire pump refers to a clean water pump used for fire water supply, and a single water pump with a treatment medium temperature lower than 80 degrees and non-corrosive. The pump unit is a joint operation of multiple fire pumps to ensure the quantity and stability of water supply. The electric motor fire pump set adopts multiple fire water pumps powered by electric motors.

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.

Learn how to troubleshoot common fire pump issues, including low pressure, cavitation, and motor failures.

The application of fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise building underpressure water delivery.

The diesel engine fire pump is usually used as a backup facility. It will only start automatically when the electric water pump fails or is powered off when the fire signal comes. When equipped with an ultra-low pressure pump starting device, the matching electric pump control cabinet should also be equipped with an ultra-low pressure pump starting device, and the lower limit of the pump should have a certain pressure difference. Of course, it is also possible to design a control system that is more suitable for customer needs according to customer requirements.

Setting up the fire pump control system correctly is crucial to ensure the pump operates efficiently and reliably during emergencies. Here are the general steps to set up the fire pump control
