Hi, i’m planning on building a vaccum resiviour and i’m not sure where to start and what materials to buy, any assistance will be greatly appreciated.
thanks
Source a used, large fire extinguisher. (100 lbs of powder or so).
You can use your own imagination, as long as it fits your needs.
hi herman, thanks for the reply, a picture of how this is connected to the pump will be greatly appreciated.
i’m planning on turning the pump off after pulling some vaccum and then let the resivour take over, am i on the right track?
I made one out of PVC pipe and used barbed 1/4 nylon fittings
==edit==
Not in a rush so here’s my full response. Like Herman said you have the correct mindset. At the simplest level you need to find a container that can hold up under pressure, and then attach the necessary fittings to allow air to escape, and then seal the container when it’s empty. In terms of prices you they can range from under 20 to a few hundred depending on the gizmos you add, like clear lid, vacuum gauge, automatic valves etc.
On the right track, yes.
If you can weld, you have an advantage. If you cant, have someone weld a couple of connectors of your choice to a suitable barrel. (an old compressor tank will do as well).
Basicly the lineup goes like this:
-pump
-non return valve (if there is none in the pump)
-filter (paper filter is enough)
-hose
-tank
On the tank:
-connector for a vacuum switch (Danfoss RT121 or similar)
-as many connectors for vacuum hoses as you want.
The connectors can be prefab 1/2" weld-on ones. (basicly a very short piece of metal tube, with 1/2" threads onthe inside).
The vacuum switch will control your pump. That way it shuts up when it is not needed, but switches on if vacuum levels fall below an adjustable level.
wow thank you very much
I use a tank from a broken craftsman air compressor. They already have a several standard pipe thread ports so they are easy to connect. Just remove the compressor pump and connect your lines.
You can usually find a used air compressor with a broken pump for pretty cheap, somtimes free
Make sure it is wide and shallow, not tall. I used to use PVC piping until some resin went off inside it and nearly melted through. Not sure if this was a fire hazard but man, it was hot.
I now use a paint pressure pot.
