Electric fire pumps are used in various water environments

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 motor fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

There are many types of electric fire pump sets, including long-axis fire pumps, vertical single-stage or multi-stage fire pumps, horizontal fire pumps, etc., and are selected based on the installation environment and performance requirements (pressurization/stabilization, etc.). Fire pumps occupy an important position in both life and production, requiring more but stable performance. As long as you choose a suitable fire pump manufacturer to ensure the quality of the pump and the correct selection of the pump, there will be fewer troubles for daily use. There are two types of seals for electric fire pump sets: packing seal and mechanical seal. Different forms can be used in different environments. The difficulty of manufacturing and material selection lead to different prices. For most users, the suitable fire pump selection material is very good. High-quality equipment does not need to exceed the requirements of good materials and oversized models, otherwise it will easily cause many failures and difficult maintenance.

    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.
