EDJ fire pump set is a fire emergency system consisting of diesel engine fire pump set, electric motor fire pump set, jockey pump, pressure vessel, control cabinet, pipeline and automatic control system.

1.Adjust the pressure switch: the upper limit of the pressure of the jockey pump to 110% of the rated pressure, the lower limit to the rated pressure. The electric/diesel main pump pressure is limited to the rated pressure and the lower limit is 85% of the rated pressure.
2. Check before the test machine: a. The water level of the main pipe is higher than the inlet pipe or the negative pressure of the inlet pipe -0.02~-0.04, b. The diesel engine water tank is filled with the antifreeze with -5 °C, and the engine oil is CF-4 15W/ Type 40, the oil is added to the oil scale display position, and the battery switch is closed at a voltage of 12V/24V or higher.
3. Test machine start: The diesel engine first turns on the manual mode, starts the diesel engine speed in the idle position (rated 3000r/min idle speed 2000r/min, rated 1500r/min idle speed 1000r/min), the water temperature rises to 40-50°C, adjusts the throttle to the rated speed. (rated 3000r/min, rated 1500r/min).
4. Connect the control cabinet into the line, switch the automatic control pressure pump to pressurize the pipe network pressure to 110% of the rated pressure.
5. The diesel engine control panel button and the electric main pump control knob are all in the automatic position.
6. Test start: open the outlet valve, the pressure drops to the rated pressure, the jockey pump automatically opens, the pressure drops Up to 85% of the rated pressure, the electric main pump is automatically turned on, and the main power supply is turned off. The diesel pump is automatically turned on (dual power supply) Switch to the backup power supply).

    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.
