Oil - The Most Important Component of any Hydraulic Press
Filed Under Hydraulic Press Care |
Here at Hydraulic Press Now we have given considerable attention to hydraulic press maintenance. One of the most important aspects of proper press maintenance is care of fluids - especially oil.
There are four things to keep in mind when maintaining hydraulic press oil:
The first thing to keep in mind is that oil changes can be reduced considerably by implementing proper filtering precautions on your hydraulic press. Oil changes are usually spurred on by contamination that results in depletion of additives. The other reason for oil changes could be degrading of the base oil. While these are both valid reasons for oil changes, these reasons can be reduced by proper filtration. Don’t ignore it, and spend a little time implementing proper filtration techniques.
Another type of contamination is by non-oil particles entering the hydraulic lines. If you can keep your fluid at a cleanliness of ISO 4406 16/14/11 you can increase your average time between breakdowns by a factor of ten. Studies have shown this to be the case, especially in some of the latest studies, some which have been lengthy studies spanning three years or more on both mobile and industrial machines. Make no mistake about it - there is a direct connection between the cleanliness of your fluid and oil breakdown frequency.
You can extend the life of your hydraulic press fluid by using additives in your hydraulic lines. Particles can strip out additives, so use additives. The additives work by attaching themselves to particles, which then make these particles large enough to be (a) caught by the filters or (b) too heavy to float in the oil, thus causing them to sink to the bottom of the oil resevoirs.
The final thing you want to do as a hydraulic press operator is keep the fluid cool. Keep the fluid cool. Oil can (and will) oxidize if you do not keep the temperatures low. If the hydraulic press oil oxidizes, the life of the oil decreasese significantly because sludge will begin to form in the lines. You’ll get clogged filters, valve spool stiction and other random crap that just makes life miserable as a hydraulic press operator.
As mentioned previously, anytime there is an oil leak, attention should be given to the hydraulic press.If any oil is noticeable on the ram, for instance, the ram seal should be immediately replaced. There should NEVER be drops of oil. Instead there should just be a very light film of oil on it.

Fine depth filtration will remove the particles that are too small to be caught by the standardin-line filters. It will also protect the in-line filters, servo valves and pumps. The usual cost savings, when using depth filtration and oil analysis, on a hydraulic piece of equipment is around $4,000.00 US.
COMO Filtration Systems is a producer of depth filtration and can help you to see these kinds of savings.
Depth filters also hold over 10# of dirt per filter and up to 1 gallon of water. Some customers see dirt holding capacity in the 40# - 70# range.
Thanks for the heads up on your company Kevin and the extra information!
