Why need to vacuum in transformer chamber before filling transformer oil and how long need to vacuum?
we need vacuum to remove moisture from tank
Why do you use a vacuum pump on an air conditioning unit?
They are used when installing, to ensure there is no air or moisture in the pipework. On large industrial and commercial systems a sight glass may also be installed so the presence of moisture can be constantly checked for.
Why do you do load test in transformers?
Moisture causes problems in transformers, and is not desired. Pulling a vacuum causes the moister in the oil impregnated paper and nonmetallic supports to evaporate, and as the vacuum is held, this moister can be removed.
How do you remove oxide layer from steel after vacuum heat treatment?
It is important to heat treat in vacuum as otherwise lots of oxides form; after heat treat in vacuum oxides are removed, if part small enough, by use of an abrasive grit pad, such as Scothbrite A, and cleaned with acetone followed by isopropyl alcohol. If not protected, however, oxides will continue to form in air
Can you assign temperature to a vacuum?
Answer Yes, you can. I think the answer is no. A physical object in a vacuum can have some energy/heat in it, and the energy associated with electromagnetic radiation can have energy/heat associated with it, but the vacuum itself cannot. ______________________________________________________________________ There is no such thing as a vacuum.
Do you have to vacuum system when changing hi switch in sable?
Anytime you open the system to the atmosphere you have to evacuate the system to remove contaminates and moisture.

Is it ok to run vehicle with a vacuum on ac system?
Yes, the heat from the engine will actually help remove a little more of the moisture from the system................

What happen if you don't pull a vacuum on an ac system?
You will not be able to charge the system correctly plus you will have moisture stuck in the system.....
How do install a new ac compressor. where is it located and what does it take to remove and replace a compressor.?
replacing freon is only possible if it has been properly been cleaned and recycled back to it's original state - the key to recharging a freon system is first to vacuum the tubes and then when it is in a vacuum - purge the system with nitrogen to rid the system of moisture - maybe twice - to make sure - then either install new freon or reinstall cleaned freon - as the system has failed - most likely due to moisture that has entered the system

What will Moisture in a vehicle's AC system will cause?
Moisture in a vehicles AC system can react with the R134a or R12 refrigerant and create an acid that will eventually eat through seals and o-rings and even orifice tube parts. It is recommended you vacuum your system whenever it loses charge or whenever your extremely low on refrigerant. You can rent a vacuum at Auto Zone for free (200$ refundable deposit) and pull a 26-28 inch vacuum.
How do you fix an ac conditioning vacuum leak?
In order to remove all the unwanted moisture and gases from the refrigerant system, a state of near-vacuum has to be achieved in which the pressure in the system is forced to go below the atmospheric pressure. The absolute value of the atmospheric pressure at sea level is given by 29.92 in. Hg or 14.696 psia In the typical system, the vacuum pump is required to create a vacuum. state of about 300 to 500 microns. An electronic vacuum gauge is needed to measure the level of vacuum in the system. Check the specifications of the vacuum pump and make sure that it is able to achieve the vacuum state as required by the manufacturers of the equipment.
