The pump types are similar, but the head and flow are different.

The diesel engine fire pump and the electric fire pump are “one standby and one use”. The control boxes of the diesel engine fire pump and the electric fire pump should be kept independent of each other, and the diesel engine fire pump must be used as the backup pump of the electric fire pump, and cannot be used as backup for each other.

The pump start signal in the fire extinguishing system is directly connected to the electric fire pump control box, and it is not suitable to be connected to the diesel engine fire pump control box at the same time. The pump start fault signal of the electric fire pump control box and the pump start signal in the fire extinguishing system are used as the automatic start pump start signal of the diesel engine fire pump control box, and the line is connected to the control box of the diesel engine fire pump. The pump start failure signal of the diesel engine fire pump control box received an alarm from the fire control center. After receiving the alarm, the authorized personnel rushed to the pump room to force the diesel pump to start in an emergency.
