    1.Product Introduction

     

    EDJ series is a packaged fire pump set,generally an automatic fire water supply system It consists of a main pump (driven by an electrical motor),stand by pump (driven by diesel engine) and a jockey pump.This model comes equipped with a separate controller,or one that is attached to the skid,The package also contains discharge valves,common header,and accessories.
     

     

    2. Working Principle

     

    Generally the pipeline network’s pressure is between the low pressure P1 and the high pressure P2.When the above pressure is lower than P1,the pressure maintaining pump will start automatically and not stop until the pressure rises gradually to P2.Due to the pipeline network’s leakage,its pressure will drop to P1 gradually,and then the pressure maintaining pump will start automatically again.with such a repeated process,the pipeline network’s pressure is maintained between P1 and P2 all the time.when the pipeline network’s pressure can’t be maintained between P1 and P2 (for instance,when the water consumption increases a lot) and drops to the minimum pressure P3,the electric pump will start automatically and the pressure will rise to Pw and meet the need for fire water supply,if the mains supply is power-off or the electric pump fails,the pressure will continue to drop from P3 to the ultimate pressure P4.then the diesel pump set will start automatically,and the pressure will rise to Pw and meet the need for fire water supply.the electric or diesel pump shall be stopped manually after human judgment (except automatic switching ).

    Diesel engine pump Specs

     

    Diameter of pump outlet:DN80-800mm
    Pump flow range :Q≤11600m3/h
    Pump lift head range:H≤200m
    Pump working pressure:P≤2.5Mpa
    Pump working temperature:T≤105°C
    Pump working voltage:U=380V,6kV,10kV

     

    The diesel engine is fixed on the base with anti-vibration rubber pads and the pump is directly coupled to a diesel engine through flexible coupling, According to the power output of the engine the electrical system,the diesel engine can be Cummins,Deutz,Perkins and Other China brand engine(Shangchai,Yuchai,ec.) and it consists of alternator, started motor, fuel system, lubricating system, exhaust system, etc.

    Electric motor pump and Jockey pump

     

    The electric pump is Horizontal Split Case Centrifugal Pump,we also can choose end suction pump and horizontal multistage pump,just as per client's pump specs requirement.

     

    The motor is squirrel cage industrial type and foot mounted suitable for 3 phase, with required hose power rating.

     

    The Jockey pump specs will be choosed as per Diesel engine & electric motor pump specifications.

     

    Controller Information

    The common controller is fabricated from mild steel and epoxy powder coated to red color. The enclosure id IP 54 rated and having all the required controls complying with the applicable standards (NFPA).

    Manual starting: If set up for the”Manual”position with the black 2# three-way switch on the control panel mode,That you can use “Manual” start button and “Manual” stop button to control diesel engine pump start or stop. when the black three-way switch to the”stop”position,diesel pump can’t work.

    Automatic starting: If set up for the”Auto”position with the black three-way switch on the control panel mode,it will receives an effective fire alarm signal to control diesel pump start or stop. Through the pressure controllers on the common outlet pipe to achieve pressure control.first, use two 1” 1.5 square signal lines to connect between the pressure controller normally open contacts and the control cabinet’s terminal No. 111 and 127. then, set a low-value and high-pressure for pressure controller to achieve low-voltage to start pump and high-pressure to stop pump. Last,if the electric main pump is overload,the diesel engine pump will start.
