Trying A Big Head Yong Heng Type Pump

[Jterrones]

I've been using one for the past few months and had some challenges early on keeping the water cool enough. I was using a bucket and it was going over temp with not even 1/4 my venturi 300 bar bottle fill. I'd shut it down and replace the water, even filled it up with ice. Didn't help much. Finally ended up filling the entire deep sink up with water and that worked. Never had a heat problem with heat after that. The next problem was with the pressure disk blowing at around 200-220 bar. Believe it's rated for around 300 bar so after three blown disks I was frustrated. Ended up using two disks instead of one. Managed to hit 250 bar before I shut it down because I was afraid it was going to blow up my house (or at a minimum scrare the crap out of me). Anyone have advise on this one?

@jtorrones, if I’m not mistaken, someone posted that when he was blowing burst discs, he found a dirty check-valve. Maybe start a new post titled “Blowing burst discs” will get the responses you need? Chances are you’ll get it sorted, good luck!

Thanks Scotty, I'll do that for sure.

I used the first big head pump that was leaking air into the water jacket tonight to fill my 74cu/ft tank from 200 to 300 bar. Even though I tightened the head bolts very well it still let a tiny stream of bubbles into the water. The pump ran well and relatively quiet. Filled from 200 to 300bar in 20 minutes reaching a max temperature of 49c using 4 gallons of water in a 5 gallon bucket no additives. I would only recommend this pump to an experienced compressor mechanic.

I'm curious as to why no one has tried just hooking the water supply on these water cooled units direct to a faucet for continuous cool water supply and let the warm outlet just drain to waste. No need for the pump or reservoir. Gpm required is very minimal

Actually, that has been mentioned directly, & indirectly in pictures, a few times. I think most don't do it, as they don't have a running water source available where the compressor is running.

Some people do that and it's common practice for many tig welders. Some people have been brainwashed into the idea that they could "waste water" but last time I checked all the water that has ever been on this planet is still on this planet less a few gallons we left in space. I think it's a great idea.

In Kalifornia we can't waste water for a continuous flow cooling system because the state is flushing 90% of our water into the ocean. The alternative is to use ice which strains our precarious electrical grid. Bought a more efficient ice chest to cut the kwh use in summer, none of this silliness is sustainable...
