Who has the circuit diagram and principle description of the fire pump control cabinet?

The control cabinet of automatic spray pump should be able to receive the pressure transmission signal from the pressure sensor on the outlet water pipe of the pump group. When the pressure is lower than the starting pressure value of the pressure stabilizing pump, the control cabinet sends an instruction to start the pressure stabilizing pump, and when the system reaches the set pressure value, the pressure stabilizing pump is closed.

When the pressure is lower than the starting pressure value of the automatic spray main pump, the control cabinet sends an instruction to start the automatic spray main pump to provide enough water for the spray system to meet the design value. Passive electric shock signal should be reserved for the fire alarm system in the fire pump control cabinet, and the bidder is responsible for coordinating and determining the reserved position of passive contact signal contact.

Extended data?

The ammeter in the motor circuit uses open scale in the normal range and compressed scale outside the working range to indicate the starting current of the motor. The open scale accounts for about 60% of the scale range, and a red mark or pointer is provided to indicate the normal full load current of the motor. Buttons and indicators

The styles of buttons and indicator lights should be coordinated. Start button and indicator light should be green, stop button should be red, emergency stop button and indicator light should be red and have self-locking function. The emergency stop button set next to the motor shall be equipped with necessary steel structure supports, trays and other accessories, and signs that can clearly indicate the controlled equipment.
