I am not sure if my sons nebulizer is working properly.?

I plan on calling the doctors office after they open up this morning, but I did not know if I could tell them that it is not working right. He has the Nebulizador Familiar A Piston / Piston Compressor Nebulizer / Model 3050/3040. The trouble shooting section mentions that there should be an aerosol that comes out of the nebulizer, but nothing but air comes out. No mist, steam, anything like that. Is it broken or what. It is new.

How does a external compressor attached to a gearbox provide air conditioning to a piston engine?

how does a piston engine aircraft consisting of a external compressor attached to the gearbox provide air condtioning and pressurization

Thanks guys

Lenox Merit Series Home AC unit will stop working during a certain part of the day?

I had a used Lenox central heat and air conditioning installed in my home a few months ago. When it’s working it cools down my 1200 sq. ft. home great. The problem I’m having is when I leave my unit on for a long period of time it stops cooling my house down, When I shut it off for about a 1/2 hour then turn it on again the compressor will kick in then it will start cooling my home again. Could this be an over charge? The installers installed a TXV Valve because the original piston wasn’t available. Any Help would be greatly appreciated. Thankyou! DSmith
Kclifer, Thankyou for your answer, I will look into a pressure switch. I also forgot to mention, sometimes I can hose the condenser down with cool water after a minute or so the compressor will kick on? That baffles me as well:)
Hey Guys..Thanks for the response. I will certainly have the unit serviced for sure! I have a few more questions if you could help me out. I’m not sure if a HARD START was installed with the TXV, what would I look for? And are they expensive to install? And, If there was an over charge is it a pretty simple process to remove some of the R-22 coolant to a normal level? I will have to get another Heating and Cooling Company to service my unit, the original installers are not very helpful and will not respond to my issues.:(

Help with physics problem! Air compression/ 1st law of thermodynamics? 10 pts best answer?

A reciprocating compressor is a device that compresses air by a back-and-forth straight-line motion, like a piston in a cylinder. Consider a reciprocating compressor running at 180 rpm. During a compression stroke, 1.50 mol of air is compressed. The initial temperature of the air is 390 K, the engine of the compressor is supplying 7.1 kW of power to compress the air, and heat is being removed at the rate of 1.0 kW.

Calculate the temperature change per compression stroke.

I have stared at this for hours and still have no idea how to solve it! Any help is appreciated!

air compressor problems.?

OK. i build my own air compressor with a 5 horse motor a single piston pump and an old aluminum tank i found. . . i built it for a "home made" FUBA system… it lets me breath underwater… but the only pressure relief i have is a 125 pop off valve that doesn’t close until it drops to just under 40 psi… and when it gets this low it make it to where my regulator doesn’t feed me are very well…. so i was wanting to use a pressure switch and a clutch on the motor or pump to make it to where it stops pumping are at like 100psi… but i don’t have any idea on how to do that….

Which way does the bolt on a Porter Cable air compressor piston turn for belt replacement?

Have a small tank compressor (not a pancake) and we are trying to replace the drive belt. The piston has to be removed from the large gear to slip the belt over it and we can’t get it to budge. We are concerned it may be reverse threads.

Please simplify this for me :D?

The mechanism of an air compressor is similar to internal combustion with a crankshaft driving a piston down a cylinder to compress valve entrapped air and generate kinetic energy.

PLEASE HELP THANKS SO MUCH!

Could I run an old 1 piston 4 stroke engine on compressed air?

I have an old 148cc Briggs and Stratton engine from a lawnmower. I want to run it on compressed air just for an interesting project but I’m having problems. I was hoping that I could just replace the carburetor with a compressed air input and that when the intake valve was open the compressed air would power the motor. I don’t have a starter for it though so I put a vice grips on the shank to turn the motor by hand. I start my compressor, and turn the motor trying to get it to start but it get’s "stuck" in one place. It feels like the piston is trying to compress against the air from the compressor. So will the engine run on compressed air with the cam and valve setup for internal combustion? Do I need to turn the engine faster for it to start or should a hand cranking it at approx 60rpm start it?
