Vacuum Receiver tank5/24
If you have a rotary screw vacuum pump are you running a vacuum receiver tank with it?
Sulliar 30 HP rotary screw.
Not sure why you would want to unless you're running a small unit.
Its a 25hp Kaeser. If you set it to Modulating there may be cycling which will cause a pulsation?
Its not hooked up yet so I am not sure, Just trying to understand what everyone else is doing. A vacuum tank is not inexpensive so I don't want to invest the money of it is not needed.
Not sure how I have mine set.
I bought it used at auction, changed the oil, turned it on and it's run 8 hours per day for 5 years.
If you have a pulsation issue it'd likely be when the pump is running and the vacuum table is off. When the cnc is running there will be a constant "leak" that will keep the pump running evenly.
We've got a 40 HP Quincy screw on a 5 x 10, No tank. I've never seen a tank used in over 20 years of owning and looking at many at the IWF show. A tank would delay coming to full vacuum, seems like a disadvantage.
Thanks Larry. We are going to plumb it in without it and see what happens.
We plumbed in the pump to our machine and this is what happens. When you load a new sheet the pump will modulate back and forth from 28" to 24" until there are enough cuts to bleed some air then it will hold at 28" on plywood.
My conclusion is no tank is necessary as others have said.
No tank is needed
Seal the edges of your spoil board with paint or glue sizing, and block off unused space
When running corian we are reading 35 and 40 vs 34 with melamine.
The name of the game is good flycut fibers, proper depth, decent suction and nesting - return onion skin strategy with smaller parts
What is reading 35 to 40?
Cabinetmaker, What are the units you use to measure your vacuum levels? Can't be the usual "Hg.
