Yongy cooling overkill!

[steve123]

I think because we use that beverage cooler the cold sinks into the motor a little too???

I could see filling a tank from empty would tax the motor so you gotta do whatever is needed to keep it cool.

We have 26 fills now, approx 20 minutes each.

Check the amp draw on the motor. As long as it stays in spec it will probably last over twenty years. That's how you set up an electric motor, by load. Electric motors have a service factor usually between 1.00 and 1.20 so if an electric motor is rated for 15 amps with a service factor of 1.15 it can draw 17.25 amps for a short time with no harm but running amps need to stay at 15 or less.

I would say the limiting factor for yong heng compressors is flex where the two pistons mount to each other. The factor told me that they increased the thickness of the big piston to prevent breakage in the first year of production. There doesn't seem to be many problems after that so I would think you could run it as much as you want as long as the temperature and amp draw stay in spec.

I have a large chiller on my cnc laser but I never saw the need to connect it to my yong heng. When the compressor was new it would overheat pretty quick but now that it's well broken in it stays cool no matter what. I do have wicking on the stainless tubes that I keep wet when filling tanks but other than that I just use plain water for cooling.

I had to empty two of my scba tanks (14L) and topping the second one right now as we speak (a second day). From absolute empty to 300 bars I needed about 3 hrs on a first tank.

I am running the YH like for an hour before shutting down to cool the electro motor. And no ice. But a 15L bucket under the tap and filling slowly with cold water to keep a level about 3/4th of height, the return line doesn't go back to a bucket - flashing it down in a sink. Never exceeds 44C, haven't seen 50C for many months.

Nothing wrong with that method. I don't see much over 50C either. I don't have a 15L bucket to handle (I use 2 gallons in a small toolbox WITH ice). I don't have water flushing down the sink. More than one way to do things and different ways will suit different people.

Good to know,, thanks.

My friend Randy might know how to check the amps. That's completely out of my wheelhouse.
