PRODUCT DISPLAY
The role of the burner: It can ensure the normal combustion of gas,
which from the nozzle high pressure injection into the burner
inside the Venturi tube, causing the pressure in the tube down. Air
(the first air) is inhaled and mixed with gas, Which will rush out
gas hole to burn. The air that is still insufficient after the
first mixing is partially mixed by the second mixing of air around
the fire to form a complete combustion.
The role of water pressure switch: In order to ensure the normal
operation of the heating system, the system is filled with water,
and maintain a certain pressure. The water shortage protection can
be achieved by detecting the system pressure through the water
pressure switch.
The function of the main control circuit board: it is used to
control the start, stop and constant temperature of the HVAC
equipment.
The role of the main board: It is used to control the start and
stop of the HVAC equipment, and constant temperature of the system.
The function of the gas valve is to ensure the normal combustion of
the boiler. In a certain range of gas pressure, make the boiler
stable combustion and can automatically adjust the gas supply
according to the requirements of the boiler heat output, in order
to realize the automatic shutdown of the boiler and gas proportion
regulation.
The role of the air pressure switch: The air pressure switch is
mainly responsible for the safety protection in the wall mounted
furnace system. It is divided into two chambers by a valve inside,
and the two chambers on both sides of the valve are respectively
connected with two pressure measuring tubes. By comparing the
pressure obtained by the pressure measuring tube, it can detect
whether the smoke exhaust system is normal.
Combined gas heating hot water furnace, suitable for residential
communities, hotels, office buildings, hospitals, schools and other
enterprises and institutions. Furnace body The furnace body is
provided with a water collecting pipe, a temperature detection
probe is arranged above the water collecting pipe, and a water
inlet branch pipe and an outlet branch pipe are arranged below, and
a heating unit is arranged between the two pipes, and a collecting
pipe is arranged at the bottom of the furnace. Supply gas to the
heating unit. Pulse ignition, water and gas induction linkage,
built-in controller to control ignition, combustion, heating water
temperature, water pump start and stop. And the heating hot water
stove has water shortage protection, anti-overheating protection,
accidental flame out protection and other functions.
The furnace body has a collection pipe, inlet branch pipe, outlet
branch pipe, circulating water pump, isolating water valve,
collecting pipe, gas branch pipe, isolating gas valve, solenoid
valve. Combustion first, its structural characteristics are: stove
below the collecting pipe, the collecting pipe on the collecting
pipe branch, the stove above the collecting pipe, the water inlet
branch pipe and the water outlet branch pipe below the collecting
pipe. There is a heating unit in parallel between the roads. The
heating unit is composed of water passage, air passage and
combustion chamber. The inlet branch is connected with the
circulating water pump through the isolation water valve, and the
circulating water pump is connected with the water diversion
device, and the water diversion device is connected with the heat
exchanger. The heat exchanger is connected to the water branch by
isolating the water valve. The combustion chamber is located below
the heat exchanger. The lower part of the combustion chamber is
provided with a combustion head, the combustion head is provided
with a pulse ignition needle and ignition needle, and the bottom is provided with a solenoid valve.
