Factory direct sales of efficient and convenient fire pump sets

The fire pump is part of the water supply of the fire sprinkler system and can be powered by electricity or diesel. The inlet of the pump is connected either to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). The pump supplies water at higher pressure to the sprinkler system risers and hose risers.
Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

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.

    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.
