Need help on airing off corrosives

I would be interested in this as well since I may soon be learning this....

 

Look at conn. on trailer for ideas reg.3/8 air line can be used or 3/4 or 1in. are most used but all depends on CFM of compressor?

 

When we use our truck air to unload tankers we just run 3/4in hose and no regulator but then again we are using the engine compressor that airs up the brakes so it hardly builds over 12 psi in the trailer before its empty.

Now if we are using customer supplied air they have regulators set for around 40psi and usually end up having to kinda watch things as we get towards the end as it will get around 20-25 psi in the tank. If it starts creapin much over 25 I will close off the air supply 1/2 way to slow the air flow going into the tank letting the pressure drop. This is also how you should set up your truck. Hard pipe from the compressor to a regulator to a ball valve to the Chicago fitting. Should be 3/4 or 1 inch plumbing and regulator with 3/4 inch hose. The smaller regulators used for home garages are normally 3/8" and will really slow things down flow wise. You would still get plenty of pressure but pressure wont unload the product if you dont have the volume to keep up with the 2 or 3" product plumbing.

 

DO NOT install a regulator on your compressor unless it goes into a tank then you could put a regulator on the tank outflow. Failing to do this could cause , safties to blow on your compressor, something blowing (like, air fittings, pipes, or compressor).

 

You need to be trained....ask.

 

Training...disconnecting a hose under air pressure can kill you...you need to be trained for your own good.

you want the most airflow, if the compressor exit is 1", you need to use components that are one inch.

Same with the air hose, we had one 1/2" and it really made the unload take longer than the 3/4" we usually had.

You need to understand how to not trap pressure in a hose and understand that even a small pressure differential exerts a bunch of force on dome lids and hose connections.

Get training. Did I mention that you need training?

 

Yeah, you need more training. I know it's late...but if you have any other questions, PM me.

Best of luck!

 

I think you need to mind your own business!

 

Cruise control is your friend. Just keep hitting accel until the engine finally starts ramping up. Think I set it about 1000 rpm. Gets you to 25-30psi easy.
