You got a muffler on you pneumatic drill? You should have. Really cuts down on the racket.
McMaster-Carr sells mufflers. See page 334 of their on-line catalog.
Now think GASOLINE.
I want to find out how much gasoline I can flow through one of those
80-micron mufflers if the gas has an 11" head.That's the basic Going In data I need to quantify.
Worse-case, I need about 5.5 gallons per HOUR.
Gallon is 234 fluid ounces (I think. Have to look that up.)
So I'm looking for a pneumatic muffler that can pass 1287 fluid ounces per hour.
That's 21.45 ounces PER MINUTE. Which ain't much. Big beer mug is 16 ounces. Mug and a half is 20.
The Hot Project is to make up a plate to hold the pneumatic muffler, which uses NPT, and plumb it to something that I can use as a gas tank. Something portable, so I can adjust the head-height to 11 inches.
But this is just a step along the way. Once I've found a sintered bronze filter that can pass the required volume of fuel I was planning to design a sediment bowl to go along with it. A Po'Boy Gascolator.
The sediment bowl is actually a water-catcher so you want it to be glass. And it has to have a drain. I've already done some experiments using baby food jars but when some fellow overseas asked 'What's a baby-food jar?' I realized I was making the design to specific.. I needed a sediment bowl that could be duplicated more easily. Which tossed that aspect of the Project into the Head- scratcher Dept.
To me, the fuel system is something you want to make as bullet-proof as possible,so there are a lot of little tests that need to be done, with good records kept showing not only the quantitative test results but with drawings showing the test rig that was used.
