The fire pump control cabinet prioritizes starting the electric fire pump; in the event of a power outage or a failure of the electric fire pump, it starts the diesel fire pump. When the pipeline network pressure drops to 0.8 MPa, the control cabinet immediately activates the pressure stabilization pump; if, after a 30-second delay, or in the event of a failure of the main pressure stabilization pump, the pressure fails to reach 0.8 MPa, the backup pressure stabilization pump is activated automatically. When the pipeline network pressure rises to 0.80 Mpa, after a 15-second delay, the pressure stabilization pump automatically stops operating ； The electric fire pump is started via a pressure switch; when the pressure in the pipeline network drops to 0.70 MPa or a remote start signal is received from the plant’s fire alarm panel, the fire pump control cabinet immediately activates one electric fire pump. If the pressure is still not sufficient, the second and third electric fire pumps are activated, while the pressure stabilizing pump stops operating automatically. If there is no power supply or if the electric fire pumps fail and the pressure in the main pipeline network remains below 0.70 MPa, the fire pump control cabinet will immediately start the diesel fire pump after 10 seconds. Some expert, please help! Thank you!
