I'm not sure if this is the best place, but here it goes....
I recently bought a 48"x"48" plasma cutting table. Well actually I bought everything but the actual table. I got all the rails, electronics, controls, computer and plasma cutter itself.
I'm looking at making a water table to cut down on the smoke produced by the cutting process. I'd like to be able to fill up to 4" and make the table the size of the cutting area 48"x48".
By my calculations, I would need about 30 Gal to fill it all the way.
My idea is to use a 35 Gal tank from Tractor Supply Leg Style Storage Tank, 35 gal. - 2137324 | Tractor Supply Company
I think with three valves I can make filling and emptying the table pretty easy.
I'd like to put one inlet air connection to feed air pressure from my compressor. This connection would be at the top of the tank above the water level at all times. When filling the table, this valve will be opened and the only place for the pressure to excape is to push the water out of the tube connecting to the table.
A second connection to act as a vent when emptying the table. This will be closed with a solenoid normally. It will be opened when draining the table back into the tank.
A third connection that will have a feed tube to about 1/2" of the bottom of the tank. This would be controlled with a simple ball valve. This would be open when filling or emptying the tank. It will be closed when the table is at the desired level.
I may want to automate the whole process with a float switch so I can auto fill the table and it will stop when it's reached the high mark. This part I will not have any issues with.
Mostly my questions is does this seem possible? I normally run my compressor to 120 PSI, but plan on putting a regulator before the tank. I'm sure I will not need much pressure. I will only be lifting the water maybe 30" to the table. The tank will remain on the ground so gravity can be used to drain the tank.
Maybe someone on this forum has built something like this before.
