Product Description
The burner adopts domestic and foreign high-quality burners, with beautiful appearance and high degree of automation. It can realize full automatic control from pre purging, ignition, automatic conversion of fire power to automatic shutdown and flameout protection.
The feed pump adopts high-efficiency boiler feed pump to realize automatic boiler feed water.
It is equipped with water level gauge, water level control alarm, pressure gauge and pressure controller to effectively monitor and control water level and pressure
Automatic control system description
The fuel gas boiler adopts a fully automatic burner with good technical performance as the main combustion equipment. The combustion program of the burner is controlled by a more advanced combustion program controller, which can realize various functions necessary for the normal combustion of the boiler, and can automatically implement protective shutdown under normal, accident and extraordinary conditions. It is equipped with corresponding water level controller and pressure regulator to realize high and low water level indication, overpressure indication Adjust to ensure that the water level fluctuates within the normal range, the steam pressure is within the allowable pressure fluctuation range, and realize the protective stop indication when the water level is extremely low and overpressure.
(1) basic operation:
Turn on the power, press the "start" key, the controller opens, the buzzer sounds, and the digital display window displays the steam pressure.
Press the "start" key, the operation indicator light is on, and the controller works according to the selected control requirements.
Press the "stop" key, the operation indicator light goes out, and the controller stops running.
(2) setting operation:
Press the "set" key, the setting indicator light is on, and the indication enters the setting state. At the same time, the setting value indicator light is on, and press the "+" and "-" keys to modify.
① Current time:
② The current time is in 24-hour system, which will take effect immediately when this setting is modified.
③ Start up time: when the current time reaches the start-up time, the boiler enters the running state.
④ Stop time: when the current time reaches the stop time, the boiler stops running.
(3) main control parameters:
I pressure control:
① The pressure regulator 1yt is adjusted at 1.26MPa.
② The pressure regulator 2yt is adjusted at 1.28mpa.
③ The pressure regulator 3yt is adjusted at 1.29mpa.
II water level control:
Water level control alarm (udz-453a-g)
① When the normal water level is +40mm, the high water level alarm is output.
② When -40mm below the normal water level, the low water level alarm is output.
③ When -45mm below the normal water level, the protective shutdown shall be implemented.
III ignition control:
The combustion program controller provides a group of independent start and stop control contacts. It can be equipped with various burners. A 10A fuse is connected in series with the start and stop control relay circuit. The start and stop control relay can be connected to the start and stop control end of the burner, and can also directly control the power supply of the burner.
(4) alarm signal condition:
① When the normal water level is + 40mm, a yellow indicator light is on to indicate the high water level state, and an electric bell sounds to indicate the high water level alarm, and the water pump stops running.
② Under the normal water level - 40mm, a red indicator light is on, and an electric bell sounds to indicate the low water level alarm, and the start-up procedure of the water pump is started.
③ Under the normal water level - 45mm, a red indicator light is on to indicate the extremely low water level, and an electric bell sounds to indicate the extremely low water level alarm, and the protective shutdown procedure is started.
④ When the normal pressure is 1.26MPa, a red indicator light is on, indicating that the pressure exceeds 1.26MPa and implementing the first-class (small fire) fire state.
⑤ When the pressure reaches 1.28mpa, the output bell sounds an alarm. When the pressure exceeds 1.29mpa, cut off the power supply of the burner and implement emergency shutdown.
⑥ When the burner cannot work normally due to various faults, the output failure alarm, the red indicator light is on, and there is an electric bell sound.
(5) indication status:
① When the water pump is working and running, the "automatic" signal light is on when it is in the automatic state, and the "manual" signal light is on when it is in the manual state, which is indicated by a green indicator light.
② High water level, large fire burning, small fire burning and other states are indicated by yellow indicator lights.
③ Low water level, extremely low water level, overpressure, burner failure and other states are indicated by red indicator lights.
(6) system control principle:
① After turning on the power switch, click the open position of the water pump control switch to raise the boiler feed water to the normal position, click the burner power switch, click the start button, the control system power is turned on, and the burner enters the working state. According to the action procedure of the program controller, carry out small fire combustion first, and then enter the large fire combustion state, and the boiler enters the normal operation stage.
② When the water level rises to the high water level, the output high water level alarm signal indicator light is on, accompanied by an electric bell sound, and the protection shutdown is realized to cut off the power supply of the controller.
When the water level rises to + 40mm, the water pump stops running. When the water level drops to -40mm, the water pump automatically restarts,
When the water level drops to - 45mm, the output low water level alarm signal indicator light is on, accompanied by an electric bell sound, and the protection shutdown is realized to cut off the power supply of the controller.
③ When the pressure rises to 1.26MPa, the output overpressure signal indicator lights up, reducing fuel supply, and the burner changes from high fire to low fire.
When the pressure rises to 1.28mpa, the overpressure signal is output, and an electric bell sound is sent out to alarm.
When the pressure rises above 1.29mpa, the third overpressure signal is output to cut off the power supply of the control system to realize the emergency shutdown of the boiler.
When the pressure exceeds the upper limit of the regulating pressure, the controller outputs a low fire signal to close the high fire valve and open the low fire valve to burn with low fire.
When the pressure drops below the lower limit of the regulating pressure, the controller outputs a high fire signal to open the high fire gas valve to burn with high fire.
④ In case of burner failure, the combustion controller will automatically close the gas valve to stop combustion.
(7) alarm protection:
After the full-automatic controller is turned on, it continuously detects the set values of pressure sensor, water level power supply and fuel gas pressure. The pressure sensor, water level power supply, fuel gas and its own circuit shall be tested at all times. In case of any problem, the alarm shall be given immediately and the boiler shall be shut down for protection. The controller will automatically display the fault point and send out an alarm sound in the machine.
