Adjusting air cylinder cushions.
Adjusting air cylinder cushions.
(OP)
I have been ask to adj. all air cushions on a machine with probable 200 or more air cylinders. Its been while since I have done this. If I remember I can open the cushion up all the way as long as the pressure isn't to high and causeses the cyl. to hit real hard. Then gradually turn the cushion in until the desired setting is acheived. I guess I could also close the cushion all the way and then start opening it until the desired setting is acheived. Does the air cushion just use the exhausting air to slow the cyl. down at the end of the stroke?
Any help would be appreciated!
Thanks Nod

RE: Adjusting air cylinder cushions.
An air cushion is really a small piston attached to the top and bottom of the larger main piston. The smaller one fits into a cylinder at the each end of the the main cylinder. When this small piston enters the cylinder at the end, it begins closing the exhaust port.
Not all cushions are adjustable. In fact, I have never adjusted one, so I can't give you any advice on how to do it. I would think closing it fully, then opening until the desired setting is reached would be the best way to do it.

Therefore you have to start with the cushions over-damped at normal operating pressure.
