I am trying to remember how an oil lubricator works?,how you adjust it?, how you know if it is working?

I am a maintenance tech at a heat treating facilty. We have air filter-regulator-lubricator systems over these furnaces there. also in other various places. The air cyclinders that lift the doors seam to struggle going up and down. I have turned the adjusting screw on top and I cannot see anything dripping out of the sight glass. Do the doors have to open and close in order for me to see if any oil goes thru the sight glass. I did one of the hexhead screws on top of the oiler and it started leaking oil. Is the heat from the furnaces affecting the oilers. Furnaces run 24/7. I can disconnect an air line or loosen to draw air out to see if the oiler will work. The doors do not open alot due to the process. There are 8 air cylinders, 6 of them operate as a pair.Only one pair or one operate at a time. So there is not a lot of draw at a time. The lubricators are not directly over the furnace. I am not sure how much heat will afect the lubricators? I would have to put a heat gun on them to see how warm they are. The adjusting screws were tight when I moved them, like they were preset and set with a little glue. I look forward to your response.

Mei, please go to the site map page, and scroll down to the Lubricators section. Have a read of the pages there.

All the answers you are looking for are there, including how much oil.

If, when you are done, I haven't answered your question, or you have another one about your air compressor lubricators, please add another question here as a comment.

Cheers,

Bill

Hi !
Every web site, book's provide much infrmation but the real question is never answer. Do we know what is the quantity of of necessary for the fonction like cylinders?
Does a rule of thumbs exist. Like 1 drop for 20 scfm.
Also: The choice of à lubricator! What is the minimum flow that lubricator need to work good!
Thank you

Denis, it is difficult to provide an absolute recommendation for how many drops of air line lubricant are required, as every application for lubrication is different.

If you view the site map under Lubricators, you will see pages providing more details about how much oil to use in an air circuit. The information also indicates the difficulty with being specific. Variable come into play like distance of the lubricator to the appliance being lubricated, ambient temperature, what the air demand of the appliance is, how fast it cycles and so on.

A visitor whom I know to be an expert in compressed air systems and air equipment writes... "Most industrial applications only need a few drops every day... once a week you should see some lowering movement in the oil level in the lubricator bowl... adjust the oil drip and fill the lubricator based on this weekly total movement."

Cheers,

Bill
