Young heng compressor

Has anyone Increased the cooling port sizes to increase coolant flow? 

Has anyone made a closed loop cooling system filled with automotive or diesel coolant?

After lots of research, I believe these modifications to the cooling system could decrease corrosion inside the cooling jacket and increase cooling efficiency. 

The automotive coolant will be less likely to cavitate and corrode the aluminum jacket cooler. I believe cavitation may be causing some of the corrosion seen in units people are rebuilding. Diesel coolants have cavitation preventative additives as well as anticorrosion / anti-electrolysis additives.I see people using water wetters. I do not believe water wetters decrease the coolant boiling temperature or prevent cavitation, or corrosion or electrolysis. They may but not to the extent a diesel coolant will. 

Increasing the water jacket port sizes can increase coolant flow. This will also probably need to be paired with larger coolant hoses and pump. 

A closed loop system with a 5 gallon bucket heat sink to me seems like a good set up. The closed loop allow for the use of automotive coolant gaining the benefits of automotive coolant. The five gallon bucket heat sink allows for the use of ice further cooling the compressor. For the heat exchanger in the bucket a copper coil could be used.



I think these additions could increase duty cycle times as well as prevent corrosion. 

Thoughts?

Yes, it's been done many times. But I have never heard back from any of those that did it. Although I bought all the gear I need to do it I don''t bother because I only need to run for 20 minutes and a half gallon jug of ice in my 2.5gal bucket gives me all the time I need and keeps it cooler than any cooling system would. If you want to run it longer you will need to cool the motor as well because these things are not made to have a long duty cycle. As far as corrosion goes I ran mine for two years with plain tap water then I put some water wetter in it hoping it would stop any corrosion going on.

I just sold a setup like that . My uncle rigged it up with a small portable cooler filled with antifreeze. He ran the pump inside it and hooked it up to a small radiator mounted on top of the Compressor. It was a Tuxing single cyl but same principle. It works just fine but its not really portable as you have to pick everything up at once and its hard for one guy to do. I think it held about 2 gallons of af. Sorry didn't take a pic..

Thanks for the responses. Good to know part of the duty cycle is the engine getting too hot. I just figured it was based on the piston head temps. 



If i do these mods i will post pics.

Wouldn't it be easier to just run a 6000 or 8000btu a/c window unit that you already have in your bedroom (you guys know why) and run flex tubing from the vents directed to feed a VORNADO using an improvised funnel ram set up pointed right at it? Along with your beer and champagne filled ice chest filled with ice and water and improved pump? Yo!

I would do that too. But the wife would get mad. Also this pump is not kid safe and the kids would hear it and come running.

MY two cents
1. The YH compessor is most definatly disigned to fill tanks not just guns.
2. Most of the heat is from compressing the air. Same energy pushed into a smaller space this happens with ALL compessors.
3. When buying a YH make sure it is a real YH not a knock off. I have had both and the knock off are what give the YH the bad rep.
4. Reducing the voltage will only make the pump draw more amps. Dont do it!!
5. Last but not least and this is a Big one. The secret to long life of YH compessors is simple, if your pump is getting hot it means you need to change your second stage piston rings. If my compressor starts getting over 60 deg when filling my 75 cuft tank from 3000 to 4500 I know that its time to change the rings. I have never timed filling my tank but I would say its never more then 10 min. And will easily go to 5000 PSI, I did this by accident one time. 

On these compessors the second stage rings are a maintance item and not a repair item and should be listed this way in the owners manual

I run a 5 gallon home depot bucket with 50/50 coolant and a bottle of water wetter. Seems to work well here in the heat of AZ right now. Actually just added the water wetter due to the 100 degree + weather. Might want to try that stuff. I try to run the pump a night when the temp is cooler. Also the reason I run anti-freeze is to prevent corrosion/pitting inside the head of the compressor. Seems this is common when running just water. The pump will still reach 57c but holds there in the heat of the day.
