Taking into consideration the sources, sizes, and quantity of contaminates when engineering a complex hydraulic system is essential. These factors can influence the size, micron rating, and location of filters
Manufacturing & Maintenance
Manufacturing and maintenance can introduce a large range of particles and solid debris. Even the most rigorous cleaning methods can still fail to eliminate all contaminants, which in turn can enter the system once it’s been put into operation. There is no guarantee that all of the correct procedures will be followed during the installation phase which can lead to wear and tear. This is why ensuring high quality filtration is implemented into your hydraulic system is essential.
Tank Leakage
Unsecured inspection plates and other unsealed joints inside the tank can introduce a great deal of dirt into the fluid, especially if the air itself is polluted.
Air Through Breathers
A majority of hydraulic systems will draw in and release air as the oil level in the reservoir changes. If the proper installation and maintenance of sufficient filter breathers are not taken into consideration this can be the main source of dirt ingestion.
Dirty Oil
Modern hydraulic systems require immensely clean standards of oil. Even if oil is described as “clean” by certain suppliers it will still be required to be stored properly and filtered before entering the reservoir.
Pump Wear
Worn pumps can introduce metal particles into your system which can create major damage. Metal particles themselves are of great concern due to their;
1. Potential to damage valves, cylinders, and motors immediately downstream.
2. Their ability to generate additional particles into the system.
3. Action as a stimulus in the fluid oxidation process.
Piping
Older pipes can introduce particles such as scale, rust, and welding slag.
Cylinder Rods
During operation cylinder rods can draw in an abundance of smaller particles, depending on the concentration of airborne dirt and the quality of the rod seals. This can be a problem specific to systems with a number of large cylinders.
System Design Consideration
Reducing the number of contaminants in a system will require a range of steps. Such as careful manufacturing and maintenance, rigorous cleaning, sealing reservoirs and pipe joints, tight seals, and so on. Even with the best practices systems will still require high quality filters.
