Easier to fix the infrared heater with spirals. Broken is easy to detect visually, and the second continues to glow. Two or more spirals, manufacturers tend to make products flexible in terms of power settings. In contrast to oil heaters, infrared are deprived of a thermostat, they are simply a block of doubling of the network on the branches, each of which is switched on by a lamp or a spiral. Today we will talk about repairing the heater. Consider the products in broad terms and hope that the review will be useful.
Infrared - many of the families of heaters. Classification:
- By type of fuel: Gas;Diesel fuel;Kerosene, other types of fuel.
- According to the nature of the heat emitter: Dark;Light.
- On electricity:
- Micatermic and similar.
We believe the classification is incomplete, but informative enough for readers to see how diverse the family of infrared heaters is. Today we will not talk about fuel models - professionals are engaged in the repair of explosive equipment. We mention that the units are simple - a burner with a ceramic stove and a pipe for joining with a balloon - and complex. The latter include electric fireplaces.
It must be said that the device of an infrared heater on liquid fuel is similar to the gas models. Inside protection against extinction of the burner in the form of a thermocouple, which supplies potential to the solenoid valve. This is how most electric stoves and gas water heaters work.
Verification comes down to dismantling the system, evaluating the performance. For example, a thermocouple is heated with a match to measure the potential at the output. This is the order of tens of mV or less. The valve is purged, the trigger is evaluated by the heated match of the attached thermocouple. If no clicks are heard, and the gas passes in any case, the fault lies here. Gas fireplaces are simpler than columns; attentive readers of the reviews posted on the website will determine or even eliminate the main types of breakdowns.
Clean the burner as well. Sometimes the heater comes with a pilot group, sometimes without. This is taken into account during the repair. In addition, behind the rear wall is a fan. In the Russian Federation, this is rarely found, but in the US they love these things. The motor is asynchronous( not an industrial model), the windings must ring. There is a capacitor nearby, check if it is bloated, is it working properly. If the windings do not ring, do not rush to throw out the motor. Under the braid, close to the coils, there is a thermal fuse, check for operability. The response temperature is inscribed on the body of the element, which is used when choosing a new spare part. You can even put a relay instead of a thermal overload, so that the protection becomes reusable. For example, KSD 301 or similar. With the right temperature response, of course.
Finally, when assembling the joints, check with soap suds. So do the wizard for the installation of gas communications. In electric fires there is a ceramic lattice. If the metal is in soot, it does not play a role in terms of performance. We mention the exhaust control system( so that carbon monoxide does not destroy people with families, as it once happened in a village near Volgograd).In the fireplaces, a coaxial chimney is used, a double pipe - one in the other - in the center air is released, and a fence is conducted along the periphery. Or in the opposite way by design. If the burner goes out, there is not enough oxygen, carbon monoxide and other harmful substances go outside. The fire goes out, the thermocouple loses its potential, the supply of blue fuel stops.
Because feedback control is sometimes not. If the air intake comes from the room, in any case, protection devices are available. For example, a pipe from the chimney to the pilot group. If the draft disappears, as a result of an increase in pressure above the flame, a part of the combustion products is supplied to the mixing device. The combination of gas and carbon dioxide can not burn. The fire is extinguished, the potential of the thermocouple disappears, the supply of blue fuel stops.
Light infrared heaters probably work on a similar principle. Heat guns are distinguished by the fact that the ceramic grille is absent, but the flame is blown by a fan( as in a furnace).By the way, a similar process takes place inside the dark heaters, where the products of combustion are passed through long pipes. Do not believe it, but the remedies are similar. The nozzle has a thermocouple, if suddenly the flame is extinguished, the unlocking potential disappears, the solenoid valve closes, the fuel stops flowing. The described control method is used in heat guns, where diesel fuel burns, for example. Moreover, the nozzle is designed so that the fuel is sucked according to Bernoulli's law, the flow of the fan( taken from a special turbine).The blades stop, the suction stops, the fire goes out, the potential of the thermocouple disappears, the solenoid valve is slammed down - the supply of blue fuel is stopped.
Heaters on fuel are the same( as geysers).For example, in traveling versions, the ignition candle stands next to the thermocouple candle. The burning control is carried out according to the scheme described above. As for ignition, a separate piezoelectric element is used( or a step-up circuit powered by a battery).Monitor the spark visually. Rarely, but there are systems with electrical ignition. In this case, the spark is punched by the formation of a high-voltage arc on the capacitor and the key element. Monitor the discharge visually( pierces from the spark plug on the body), repair the circuit if there is no bluish lightning.
Many will notice that electric stoves and other devices are arranged in a similar way. Household appliances from the inside is based on the same elements. Although the modes of operation are specific. This is observed by the example of bimetallic plates used in household appliances:
- Oil Heater.
- Electric kettle.
As for the sensors, the sensors form the operational basis for the protection relays of refrigerators. Knowing the basic principles, it is easy to understand the device of household appliances.
The device of a convector heater includes a case, a heating element, a thermostat. The body is specially designed so that air enters from below and exits from above. Due to this, the flow naturally blows the heating element in the form of a plate of arbitrary configuration.
For example, Electrolux is the letter X. This is done so that the heat release goes in accelerated steps. The thermostat stands below, in the path of the incoming air flow. Already guessed that this is a bimetallic plate, adjusted by a screw to the desired mode. Outside, the regulator looks like a knob. Meet also digital systems with sensors on thermistors or thermocouples. This will allow the processor to flexibly handle the settings( set the most accurate parameters).In the auto repair tester video of the 50s, it is shown that thermocouple contacts are permissible to slightly bend if the modes are not as specified. Convectors can not be dry things, it violates the thermostat. The heating element will remain on until victorious - until the item lights up.
Other devices are additionally supplied with air ionizers and humidifiers. To repair a convector heater, you need to find out what is included in the equipment: what will break. Try to present the main faults in advance.
It must be said that the device of an oil heater differs little from a convector. Let's say more: the last one is included in the trimmed version. It is not joke. On the side of the accordion is an electronics unit, where air travels from the floor to the ceiling of the compartment. Inside there is a bimetallic plate, on the other hand there is a flat heating element - the edge of the extreme section, a convector in its pure form without a tank with oil.
Add, inside the tank( usually double) TEN, sometimes burning. Then you have to fix the oil heater, turn to the tin master. The reason - sections are rolled, as well as heating elements. Tank holes are eliminated by liquid welding( if there is no choice), inside you will see a pair of safety devices. This works on the principle of shutdown when the temperature exceeds a critical value. As protection will act thermal fuses, relays.
We hope that readers now know how to fix the heater. It is important to understand that the units consist of identical parts. By picking up an unfamiliar model of the heater, you will be able to fix it. Learn the materiel, and the process will turn into a fascinating activity. For example, each of our regular readers knows that in an oil heater, the tank is 85 to 90 percent filled to create an air cushion.
