    The minimum fire rated pressure of ED small fire fighting package set water supply equipment is 3 bar and the minimum fire rated capacity is 25 GPM. ED small fire fighting package set water supply equipment includes at least two power or power source driven pumping units, pressure tanks, pipes, valves and accessories, measurement and control instruments, control cabinets, outdoor rain cover, etc.
    Motor: Three-phase asynchronous squirrel-cage motor independently developed and manufactured by our company, which can be controlled in production time and greatly shorten the whole set production time.
    Diesel Engine: According to the different parameters of customers, we will choose diesel engines with high cost performance ratio. The main brands are QuanChai, Weichai, ShangChai, FAWDE, Cummins, etc.
    Electric Pumps: Electric pumps can use vertical in-line pumps, horizontal end-suction pumps, vertical multi-
    stage pumps, horizontal multi-stage pumps, split casing pumps and so on according to the different flow and head of customers.
    Diesel Pumps: Diesel pumps can use vertical in-line pumps, horizontal end-suction pumps, vertical multi-
    stage pumps, horizontal multi-stage pumps, split casing pumps and so on according to the different flow and head of customers.
    Electronic Components: The main electric components is CHNT, if Schneider or other brand electrical are need, should mention it before place the order.
    Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
    Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.

    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.
