Perry Oscillating Pump Smoke - it's WORKS???
hey guys
all of you the "smokers" RC guys,
did anyone try this Perry Oscillating Pump Gas & Smoke for smoke system?
i have one airplane with smoke system with smoke electric pump... but i have another one, and i want to make smoke without "electric smoke pump"...
so......... this "Perry Oscillating Pump Gas & Smoke" is working? anyone try it?? or have other "working" idea for smoke without electric pump??
Thanksssssss guys!
i added pic and link to his "Perry Oscillating Pump Gas & Smoke"...

RE: Perry Oscillating Pump Smoke - it's WORKS???
Excellent idea. I just wonder how you would turn the smoke one and off as this would supply pressure as soon as the engine is cranked? Do you put a servo actuated valve in the line like you do in using an electric smoke pump? If you do, what effect would that have on the Perry Pump with it pumping against a closed exhaust port?
I too would like to have some feedback on this as I would love to put smoke in my new Yak 54, and in the Goldberg Ultimate I will be picking up soon using the gift card Christmas present from my sons and their families.

RE: Perry Oscillating Pump Smoke - it's WORKS???
I'm not shure i'll use it...
anyway this Perry Oscillating Pump is for use without electric pump...
about close and open the smoke, i'll use mechanic oil-valve with servo.. like this one..
look on this link.....

Wow! Who said you can't teach old dogs new tricks. You have really enlightened me, and no, I did not come in on a load of pumpkins, and although I was born in the dark, it wasn't last night! LOL!
In replying to your original post I really blew it on the question when I asked, "what effect would that have on the Perry Pump with it pumping against a closed exhaust port?" What I intended to ask was, What happens with the pump pumping against a closed valve? It would appear to me that the pump would be what we commonly call, "pumping to a dead head." With no outlet for the pressure from the pump with the valve in the "off" position like when cranking and taxing, won't the possibilities exist for leaks and possible damage to the pump since there is no way to turn the pump on or off??
Just a thought, because I really like your idea and would strongly consider using it rather than on of those expensive smoke systems available.

RE: Perry Oscillating Pump Smoke - it's WORKS???
but if you cut the oil to the pump, wont that cut the smoke off as well? stop making the smoke in the first place rather than trying to stop it from exiting the plane...

I expect your correct on that, but what happens to the pressure generated by the pump? If it was being used to pressure the tank to force fuel to the engine, it would always create a positive pressure on the fuel tank with the pressure being relieved by way of the fuel going into the carburetor, but if that line is blocked by a valve, the pressure would continue to build up, somewhat like a balloon under pressure. If not vented or relieved, the balloon will eventually explode and make a mess all over the place. Same thing can happen when a pump is "dead-headed," or pumping into a tank that is full and no way for overflow or to vent.
I don't know about this application, but am somewhat familiar with balloons and pumps pumping and the outlet being valved or blocked off (same effect). I really don' know, but would like to know as there has to be a way of either venting the pressure created by the pump, or turning the pump off. Like I said, I was . . . born in the dark!! LOL! Surly, someone out there has some information. Of course, that information might be with the instructions as it is a pump for a smoke system. I just don't want to spend the money until I know. I'm not real fond of spending my hard earned cash on something like this until I know the details!
Sorry if I have muddied up the water for you. It is an excellent post on a subject that I had some interest in. Perhaps someone with experience using the Perry Oscillating Smoke Pump and Valve will join in the discussion and straighten me out.
I'm just looking for an answer or some insight into the matter before I go out and purchase a set up like this. Gosh, I may be all wet on the matter or making a big deal out of nothing. If so, someone please tell me! I'm just kind of fond of getting the lesson before the test, not afterward!!

RE: Perry Oscillating Pump Smoke - it's WORKS???
by the looks of the towerhobbies description, this is a mechanically powered pump that uses the vibration from the engine to swing something within it , and makes no mention of any smoke being produced... quite ingenious, i think
if you cut the flow to the pump, it should literally be sucking at vacuum, which i imagine is a lot less harmful than pumping against a dead head... altho the effect is not going to be instantaneous

RE: Perry Oscillating Pump Smoke - it's WORKS???
Or here is another idea that will not block the pump pressure.
Since it will always pump off the engine vibrations couldnt you just vent it back into the tank and let the oil loop over and over. Then to move the oil to muffler shut the valve to tank and open the one to the muffler. Maybe have both valves in line with one servo and use push pull to open one and close the other.
I never tried this just an idea but seems like it would work. Kind of made me want to try this out now since I just typed it..haha

RE: Perry Oscillating Pump Smoke - it's WORKS???
yes, that is a good idea, since its a servo that is dividing the flow of the oil, we could have proportional control over the amount of smoke that is generated while keeping the pump working at spec, i.e. full flow at all times...but that means extra plumbing
abit off topic, but seeing that the pump uses nothing but engine vibration to work, cant we use it to pump the fuel of the engine , into the engine, and make some kind of supercharger for 4 strokes?

Hey is there any reason you couldn't use one of those bladdered tanks for smoke oil. Hook the one side to muffler pressure just like the fuel tank and then just have a servo actuated valve to run it?

RE: Perry Oscillating Pump Smoke - it's WORKS???
I was just browsing these forums and noticed this thread. There is an rc nut out there, Don Giandomenico, who has devised a neat smoke system using dubro smoke valves, perry pumps and a dedicated smoke servo. Here is the site [link]http://www.rcdon.com[/link] Go to the aircraft video section and watch super smoker part I and II. It is very informative. I have replicated the system and it was fairly easy, but I have yet to fly it yet to see how it works. Good Luck
