There’s no genius in dumping oil or changing components until a problem goes away…..Anybody can do that!
The fact that over 75% of all hydraulic failures is contamination related, behooves us to look at oil cleanliness as a top priority.
1. The number of contamination particles in the hydraulic oil directly relates to the amount of maintenance of hydraulic systems.
If you double the number of particles in the oil, you increase the wear of the components, If you cut in half the number of particles, you cut in half the amount of wear of the parts. Virtually all pump, valve and cylinder maintenance repair requirements are caused by particle contamination.
2. Water is a poor lubricant.
Hydraulic systems use hydraulic oil to lubricate parts and transfer power. Water in hydraulic oil creates friction of the moving parts, which produces more particles in the system. Removing the water eliminates the friction. Because of the sheer size of your power unit the more surface you have to allow water to condense and enter your hydraulic system.
3. If particle and water contamination are removed from hydraulic oil, component life will be extended dramatically.
It has been demonstrated, that by the use of an off-line filter increases the life of hydraulic components by a minimum factor of 4 and a maximum factor of 14. This means that maintenance costs of hydraulic components can be reduced to between 7 and 25% of original costs.
4. The only way to filter and remove water effectively is to do it 24 hours a day, 365 days a year.
Never stop filtering and removing water. As soon as a filter is removed from a hydraulic system, particle numbers grow in the system. Particles in a system create more particles in a system, due to increased wear and friction, and they increase exponentially. Within 48 hours of removing a filter unit from a hydraulic system, particle levels will have doubled. The wear on the components in a system will have doubled, also.
Off-line Filters/Separator cartridges have the ability to filter and hold large quantities of solids at a very small particle size. It has been demonstrated that these cartridges have a particulate holding capacity of over 15 lbs. per filter cartridge, while maintaining a nominal filter rating of 0.8 micron, and an absolute rating of 3 micron. This dirt holding capacity generally leads to a cartridge insert life of about 1 year in most applications, (depending on oil type). Cartridge cost: between $150 – $280 each depending on the filter system used.
When all is considered you will see the advantages and cost savings in the long run of utilizing an off-fine filter system. The payback on this system would be very short and from then on it’s on the job for many years as inexpensive insurance.
