Repair of oil heaters with their own hands

click fraud protection

Oil-filled elektrootopiteli - popular in household units, characterized by a high durability, since their production is performed in an industrial environment using modern technologies. However, these appliances are not designed for resistance to all emergency situations in everyday life and still fail.

The device even the most advanced machine allows in some cases to perform the repair of oil heaters independently.

Consider this popular home heating from the perspective of assessing its recoverability after exit down as needed to repair the oil heater with a safety guarantee for its future operation.

Common faults of the oil heater, their symptoms and how to repair

Remedy elektrootopitelya oil-filled, as well as repair of the infrared heater of any other kind, requires certain skills and adherence to certain rules.

Important! Failure of any of the structural elements of the oil heater heating operation must be stopped until repaired.

First of all, should be aware that the recovery efficiency of the majority of the components heater in the home is not possible or requires professional knowledge and skills. Experimentation with hors de electrical components may have unpredictable consequences (electrical accident, termotravma, fire, explosion), so oil heater repair their own hands, without training, in most cases, you should only by replacing dilapidated details.

In addition, the repair elektrootopitelya necessary to satisfy the following rules:

  • the device should be unplugged from the outlet;
  • heater must be cooled down to room temperature;
  • equipping the device with homemade accessories is prohibited;
  • should avoid contact with the body of transformer oil, as well as wiring insulation;
  • Replacement of regular mains electric cable to the ground without dwelling on the earth wire is prohibited.

oil leak

Violation of the oil cooler leak occurs usually when it mechanical damage or corrosion caused by the defect of the protective paint coating.

When used for a long time, the usual drip oil cooler, a natural question arises, what to do, why not try to restore the integrity of his own hands?

However, repair of the infrared heater in the home in case of a leak is possible only under the condition that the device - aggregate national old-style production with a steel heat sink and removable flat execution TAN.

Flat oil elektrootopiteli domestic production of steel radiators

For the production of repair of the instrument body control unit is disconnected, under which there is PETN. Then, after disconnecting the heater contacts unscrewed and oil through the mounting seat merges into a clean container. residual oil drained, whereupon the radiator is filled with water to prevent the ignition of oil inside it.

The wall thickness of such radiators is 1-1.2 mm, which allows using electric welding. Leakages on the body cleaned grinder with sanding disc or manual - rough sandpaper. Depending on the location and size of the lesion, the patch was cut from steel of appropriate thickness, it is applied to a mouth and scald using semiautomatic Kemppi.

Weld cleaned and sanded, and then boil again, if necessary. After degreasing spot repair paint heat resistant paint, for example, Rustins High Heat Black Pain.

Important! If the heater is painted by powder technology, then for repairs need to strive for a minimum cover damage - in a domestic environment can not restore it.

After drying radiator fill 80% oil, and a heater assembled in reverse order.

If the oil heater before performing repairs clicked when heated, do not expect that the clicks will disappear after tightness recovery - coupling housing parts are deformed with increasing temperature and wherein crackle.

Repair finned radiators oil heaters not expedient, since they are made of a thin steel sheet using laser welding. Restoration of the tightness of these tanks is technically difficult, in a residential area does not guarantee success or the cost is comparable to the cost of a new heater. Furthermore, if the heater is not removable, the oil can be drained through the damage, but it back fill will no longer be possible.

No heating

Technically defective oil-filled heater home when the network quietly bursting. This factor is not dangerous because it is due only to the expansion of prefabricated housing unit that snaps when heated.

If after the assembly and installation of the required power and temperature values ​​of the heating device silent, it means that the radiator heating does not occur, and the problem should be sought in the electrical part.

First of all, visually inspect the integrity of the electric cable. If there is no visible damage, you must first be removed from the bottom of the rack unit enclosure with wheels.

Then you need to disconnect from a radiator the control unit, which on top of it with a screwdriver to hook and removed the nominal sign saying Do not cover, under which there are fixing screws.

The location of the fastening screws of the control unit to the body

Unscrewing the fastener from above the bottom of the control unit is also given to a detachable fixing screws or springs (in depending on the model), with the block joint edges with the radiator shroud is removed and the assembly dismantled is placed inside side out.

The sequence of dismantling the control box to the housing of the oil heater

Produce a visual inspection of the integrity of the wiring and insulation, as well as the quality of the contacts in the joints of the wires, paying attention to areas with corners and oxidation. The wire with a clear internal damage is replaced by a new, oxidized contacts dismantled, cleaned with sandpaper and collected again.

Upon completion of a visual inspection proceed to the "continuity" of components using Testori - multimeter, which begins with a test wire strands portion of the plug to the nearest connection. Operation is simplified by different colors lived in appliance cable, making it easy to track the direction of the wiring.

Beep Testori indicates prozvanivat portion integrity, no signal - of the damage.

Replacing the tubular heater

TEN, other than heating, is equipped with the outside fuses for current and temperature, the presence of which must be considered in continuity. There is a possibility a situation where at the proper PETN burned one of these fuses, or even out of order two.

Fuses PETN left - on temperature, on the right - the current

If the test still showed the failure of the tubular heater, then further actions depend on the method of installation of heating element in the radiator. Threaded mounting the heater in the absence of the rolling allows to perform its replacement. In this case, the heater can be turned out from the radiator and replace it with the replacement of the gasket is set with identical parameters heater power and turn off temperature.

Tubular electric threaded installation method in the heater

When nonremovable embodiment seamed heater installation in the socket radiator. razvaltsevat old and install the new heater in the domestic environment by doing it sealed rolling, it is very difficult, so you should think about buying a new oil heater.

Problem Temperature Controller

Testing of this assembly is as follows:

  • prozvanivat chain portion of the plug to the thermostat;
  • regulator set at a minimum temperature and tested - chain must be opened;
  • while turning each of the heaters individually, as well as two heaters at the same time as the temperature controller set to a nonzero value circuit should be closed.

If the thermostat continuity test showed his fault, that is, the oil heater is not responding to power switching modes or change the temperature by turning the flywheel device must be replaced, as the diagnosis of its technical characteristics and then repair the results of testing in industrial conditions are not suitable, and to do this in living conditions are extremely complicated.

In the absence of fault controller is purified from dust and tighten contacts.

Failure of the bimetallic strip

Question, oil heater, actual, as the oil pressure in the radiator can explode if It reaches high values, and the air "cushion" in the form of 20% of its volume is still limited potential. To avoid this, in the present design of the heater thermostat, which should switch off the heater in case of overheating.

Under normal conditions, the relay constituting a bimetallic lamina should close the electrical circuit. If the multimeter circuit ascertains this thermal fuse, it should also be replaced by a new one with the same characteristics.

Continuity of oil-filled heater thermostat and thermostat appearance

Oil heaters explode rarely, precisely because they have several degrees of protection, overlapping, and the probability of a simultaneous failure of all devices providing safety, small.

The absence of disconnection of the heater rollover

Opening of the circuit when the oil heater is tilted or inverted by a device, the operating principle which is based on the presence in its structure suspended sinker which, when the vertical deflection unit retains its position.

Testing of devices produced by the vertical deflection heater manually. If you turn off the device does not occur, the element must be cleaned of dust and costs, and better - to replace the new installation is not difficult.

It should be noted that in case of failure of the circuit breaker oil heater does not explode - Overtemperature Heaters, not covered with oil, thermal protection triggered tubular heater or opens an electrical circuit thermostat.

conclusion

Oil cooler - a device to diagnose where the problem is quite real, but the repair of the device for its forces better to minimize the replacement of defective parts with new parts as features of operation (danger factor using electric current, the high pressure and the oil temperature) require skills and attention to execution of works.
