Compressor Burn-Out

The first thing you must install the replacement of the compressor was the nature of the error. Of course, if it was a mechanical problem, such as a broken connecting rod, change compressor a relatively simple. In case of electrical failure, cleaning is rather specific. Many times a service company can't seem to keep the compressor is in operation in a particular installation. The reason-incorrect procedure was followed.

The severity of emotional burnout sometimes, when the refrigerant line bled. The smell of burning refrigeration oils unmistakably aggressive. Exercise extreme caution in regard to the exhaustion of vapor; if you keep your skin and eyes. Always assume the oil has acidity, and you don't get into any trouble.

When the system pressure is equalized with the atmosphere, and start taking compressor escape from its valves and pipelines. Assume nothing, spill some oil from the old compressor in a clean jar.
Perform a litmus test acid kit. Direction to come in each set. Even when there is no unpleasant smell for cooling oil, acid, still could not be present in the system. If you do not, and acid, present, insulation new compressors winding will be attacked and destroyed by causing electrical problems. Time between installation and the failure is regulated by the concentration of acid in oil.

The first thing you need to do is keep the system acids. On most commercial units using the - semi-hermetic compressors changmg oil is relatively easy. There are two schools of thought about the acid cleaning system. Change the suction line filter-driers are often, and another is often to change the oil. I saw that the oil and the filter is the only way to do a thorough job. Oil acts as a sponge absorbs water and acid. It may take a few oil changes with a few hours of operation of compressors, before all traces of acid removed.

In some commercial structures, when the evaporator is lower than the condensing unit, it helps to place a drain valve at the lowest point of the coil. This valve is used for drainage of the oil, which can be caught in the evaporator. The new compressor is in operation,

the oil level be milflt AeM and IWHlflht tfl tllfi M WW TlUS on most of semi-hermetic compressors with Carter, a sight glass.

When working on the hermetic compressor installed at the residence of the cleaning process is slightly different. All manufacturers of compressors to place the consumption of oil in the compressor when shipped from the factory. Compressor, you can change also has a plant oil free. Oil quantity is measured in ounces not very many, even a few ounces, what you need, this can create problems in the compressor. For this reason, care should be taken to measure the amount of oil released during compressor change.

I carried kitchen measuring Cup with a 32 oz capacity. When the compressor has been removed from the Cabinet of the unit, I would pour the oil from the compressor in a measuring Cup. If the compressor was 14 ounces potential, and only eight ounces were in a Cup, six ounces were still in the system. With the use of nitrogen enough pressure can be put through a pipeline for removal sue ounces. R-12 refrigerant can also be used as a cleaning agent to remove contaminated oil from the system.

After all this, install the suction line filter-dehydrator. In most cases, residential units were not equipped with them. Some liquid line Hairdryer. If the device you are working with liquid line on the earth, change it and then install the suction line of the earth. I also recommend the use of flare fittings on the suction of the earth, if possible. Suction line drier must be changed after the launch of the block for a few days. There should be about 40 hours filter. Of course, that's only the average. Cleaning is very poor tramp requires a filter-dehydrator be changed within a few hours after the initial launch of the new compressor.

It is difficult to get an oil sample from a small hermetic residential unit. For this reason, make your cleaning suitable. Oil can be felt in the hot gas discharge line. This oil should only imagine how in the mist evaporates. If it feels like a drop of oil, the system has inflated the price of oil. This is a situation that can cause problems with compressor, depending on the amount of excess fat. The only way to remove some of them, allowing them to escape from the discharge line. Of course, this method requires to cover the cost before you leave the unit.

The acid test-sets are a valuable tool and is not used quite a lot of equipment. In many commercial preventive maintenance programs that you implement, it should become a standard procedure to take litmus test unit once a year. In many cases, the compressor can be maintained, oil change. When the acid begins to form, but delete before attacking the windings of the motor of the compressor, it will not hurt. Years ago, acid sight glass was used on large commercial units. It was a beautiful sight glass piece of copper in the place where the indicator of humidity. When the technician checked the level of the refrigerant in the sight glass, he could see if any deterioration occurred with fine copper wire. If so, then attracted his attention, to start neutralization program. He immediately started oil changing keep under constant control acid sight glass to see if it has progressed and stopped. Ive not seen this type of sight glass in parts of houses for a long time. Stop things before they happen most of your work. A few drops of grease in the bearings the motor stops purring and prolongs engine life.
