Features of automatic control and fault protection

Boiler steam pressure automatic regulation system

When the control system of the boiler steam pressure automatic regulation system enters the working state, when the necessary conditions for combustion are satisfied:

When the steam pressure in the pot is higher than or equal to the set upper limit of pressure, the control system outputs the stop signal.Until it stops burning.

2 Feed water control:

When the system is working and normal, start the feed pump, the water pump is working, and the water level differential pressure transmitter detects the water level signal to keep the water level of the pot stable.Ensure the quality of steam.

The water level regulating instrument shows the boiler water level.

3. Manual control: The water pump can also be manually controlled by touching the key on the control panel.

Fault alarm and protection

The control system can monitor the current working condition of the gas-steam boiler in real time and carry out real-time and comprehensive intelligent fault identification and treatment.The control system can diagnose and deal with the following faults in real time:

1. Protection of extremely high steam pressure: When the steam in the pot is overpressured, the control system will immediately enter the chain, and sound and light alarm will be given, and the screen will display "extremely high steam pressure".After the fault is eliminated, press the reset button to break the chain.

2. Water shortage protection in the boiler: in case of extremely low water level failure due to pump failure or other reasons, the control system will immediately shut down the burner's power supply, enter the chain, and alarm with sound and light, and the screen will display extremely low water level.After the fault is eliminated, press the reset button to break the chain.

Ultra high boiler water level: when the water level in the pot is higher than the upper warning level, sound and light alarm will be given.Prompt "ultra high limit of water level in the pot", the display screen prompt drainage.Automatic recovery after the fault is eliminated, stop the pump without stopping the furnace.

4. Overload of water pump motor: heat relay action when the water pump motor is over current, cut off the power supply of the water pump motor, and stop the water pump, which is realized by hardware.

Power failure: In case of power failure, the control system will immediately shut down the power supply of all equipment in the cabinet where power failure occurs.When the power is restored, the cabinet will be in the off-duty state automatically. It is necessary to restart the machine and start the equipment to ensure the safety of the equipment.
