Dirt is the main issues I see in these systems. When you do your sampling you should look at how clean you fluid looks. If you start cleaner you will have less issues.
totally agree and sometimes the dirt may even be in the container of new oil! Having clean oil to start with is critical, as well as the proper filter elemet to control dirt in the system, and potenial engress into the system
appreciate the feedback - naturally demending upon the operating environment, indoor or out, different contaimnents will occur - and system configuration makes a big difference too.
Most of the times we found that Dirt is not Dirt but WEAR PARTICLEs from the pump, valves, cylinders actuators, etc. sometimes those metal particles ammount to 80 % of the contamination!
Agree with Otto34 that most particles are most likely wear metals. Hydraulic systems are closed systems, and therefore are not prone to dirt ingress as others (e.g. lube systems).
The dirt contamination I've seen has been mainly introduced into the oil due to poor storage and handling conditions of the oil prior to introducing into the system.
If varnish deposits are leading to sticky valves and you need to reduce your particle counts, please contact me or go to our website for information. www.kleentek.com
