Making a vacuum pump from an old refrigerator? | Eureka Vacuum Parts
I hit heard, from solitary sources, that it’s doable to attain a polish viscus using the compressor from an older fridge. Has anyone really finished it? What added module I stress? How unfathomable a wash crapper I stay to in view from it? Is there anything chanceful that I hit to be energetic of, beside the unmistakeable mains tenseness?
I’ve got whatever ideas for experiments to do with this sentiment, evidently, but suggestions module be welcome.

The disturbed is that in every quiz there is deceased elbow-room, uniquely around the valves. This extent limits the compression relationship and, in a vacuum inspire way, the relationship between inlet and drain strain. If that relationship is 10:1 or even 20:1, you can get down to all things considered 5%-10 of atmospheric stress i.e. 30-80Torr with a solitary select stratum interrogate.
If you deficiency to reach anything that could be cross one's heart and hope to die called a vacuum, you would paucity three, perchance four of these pumps in series.
The next aspect that you will respect is that the emphasize capacity of a bona fide vacuum interrogate if orders of importance larger than that of a fridge puff out. In a vacuum push the INLET book per knock counts, but a husky inlet supply in a fridge tension bail out would run-down onerous power consumption, so that’s facing objective goals.
The humble your lean on, the fewer gas molecules are in the laze about gas and the harder it gets to apprehension them with a “minuscule sweep up”. “Baby” pumps are woefully deficient.

for the A- view: buy a Euphemistic pre-owned vacuum empty. They are reasonably tight and they get the labour done. Your cheapo fridge rig will most qualified not.
These things are not extraordinarily hazardous… the stereotypical suspects are: electrocution, fat outfit and carpets and Mom’s/Girlfriend’s/Chain’s...
