After the system control principle of vertical gas-fired steam central heating stainless steel pellet boiler for sale is turned on the power switch, click the pump control switch to turn on the position, carry on the boiler feed water to rise to the normal position, click the burner power switch, click the start button. The power supply of the control system is turned on and the burner enters the working state. According to the operation procedure of the program controller, the low-fire combustion is carried out first and then into the fire-burning state, and the boiler enters the normal operation stage. When the water level rises to the high water level, the output high water level alarm signal light is lit, accompanied by the sound of the electric bell, and the protection shutdown is realized to cut off the power supply of the controller. When the water level rises to + 30mm, the pump stops running, and when the water level drops to-30mmm, the pump automatically restarts, When the water level drops to ±50mm, the output is extremely high, the warning signal light is lit at the very low water level, accompanied by the sound of the electric bell, and the power supply of the controller is cut off by protecting the shutdown of the furnace. When the pressure rises to 0.72MPa, the overpressure signal, the sound of the electric bell, alarm and cut off the power supply of the control system to realize the emergency shutdown of the furnace. When the pressure exceeds the upper limit of the regulating pressure, the controller outputs a small fire signal to close the fire valve and open the small fire valve to burn in a small fire. When the pressure falls below the lower limit of the regulating pressure, the controller outputs a fire signal to open the fire valve to burn the fire. When the burner failure occurs, the combustion controller automatically closes the valve to stop combustion. When the exhaust temperature is higher than 250 ℃, there is a blue light, accompanied by the sound of the electric bell, and the protection shut down the power supply of the controller.

Steam central heating stainless steel pellet boiler for sale plant how to judge the phenomenon occurs when less water is already the minimum water level inferior to a predetermined height, the water meter water level can still be seen, is slightly less water; water was observed when the counted water level can not be measured when, for severe water shortages. Status summarized below: inferior to a predetermined height (1) Drum Level reasonable level height; (2) low water prompt, automatically sounds an alarm, warning lights; (3) the superheated steam temperature is increased; (4) the amount of water unreasonable, less than the amount of steam; (5) increase the temperature of flue gas emissions.

Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of central heating stainless steel pellet boiler for sale welds is more guaranteed.

Recommend siting the central heating stainless steel pellet boiler for sale room and the location of the cell site visit in accordance with the relevant provisions of the above-mentioned gas boiler room design, only the lawn area above the garage of imports in line with site conditions. 1. Since underground garage height is limited, coupled with the explosion vent port without reasonable position, can not meet the specifications of the boiler installation, boiler room should be considered semi-underground structure, i.e., the building height of 2 meters above the top layer in the garage, according to the total height of the boiler room 5 m design. 2. Semi-basement boiler room structure is met by installing the boiler, also addresses the regulatory requirements of explosion-proof explosion venting port, ensure safe and efficient operation of the boiler room. 3. supporting auxiliary boiler, circulation pump house, water treatment facilities have been installed in the negative layer. For abutting against the original return pipe line system. 4. The second heat exchanger unit to be installed in the basement area, respectively.
