🔎 Quick Fact
In Australian mobile and mining hydraulics, heat thins the fluid and dust never sleeps. Together they multiply wear, shorten valve life, and drive varnish. The simplest lever is cleanliness control from the drum to the return line.
🔬 How It Works
Particles and hot oil team up, like sandpaper riding the pump and valve clearances. Fine solids cut surfaces, then oxidation bonds their fragments into sticky films that slow response. As a result, components run harder, seals suffer, and downtime creeps into the schedule.
🧠 Advisor Tip
Set and trend a cleanliness target using ISO 4406 (a particle count code for fluid cleanliness). Choose filters validated to ISO 16889 (the multi-pass filter test) and keep breathers efficient. In practice, control transfer steps, sample from a live zone, label dedicated hoses, and record results consistently.
