Hydraulic systems are used in industrial, mobile, and aviation applications to deliver power to various pieces of equipment. These systems are compact, highly efficient, and lightweight compared to mechanical equivalent systems. Hydraulic fluids introduce a force into the system and are carefully selected by the maker of the system. Companies can benefit from hydraulic oil analysis services. Cedar Rapids, IA is served by these experienced providers in the hydraulic oil analysis sector.
Viscosity, chemical stability, fire points, high flash, and oxidation resistance are all valued. As a result, synthetic and mineral hydrocarbon fluids are selected for mobile and industrial systems. On the other hand functional chemicals that include phosphate esters are chosen for dedicated industrial and aviation applications.
Oil Analysis to Evaluate Performance
The only way to determine if the hydraulic fluid is impacting expected performances through monitoring hydraulics with hydraulics oil analysis services. Failure is caused by contamination much of the time and this can include dirt ingression or water contamination. Hydraulic systems contain filters and structured monitoring is performed in order to identify signs of contamination and associated wear, and also to establish the success level of the filtration.
Hydraulic system tolerances are generally quite tight. Servo valve clearances are generally around 40 to 80 µm in the clearances on actuators may be considerably lower at 10 µm, such that particles bigger than 4 µm may impose serious problems on hydraulic systems. The measuring of particles in hydraulic systems can be evaluated according to ASTM methods, ISO codes, and SAE guidelines. These codes and other techniques often identify particles by size and concentration
Manufactures of hydraulic systems will often indicate what ISO code should be used when evaluating system cleanliness. For example, On the other hand, an 18/16/13 ISO code may be used for an actuator and valve. On the other hand, a 20/18/15 ISO code may be applied to a pump in hydraulic system.
Water as a Contaminant
Waters the other contaminant often found in hydraulic systems. This contaminant can cause oxidization and corrosion of the hydraulic fluid. Often water contamination should be under 2500 ppm.
Other important parameters to monitor include: particle counting, kinematic viscosity, total acid number, elemental spectroscopy, oxidation by infrared analysis, and wear debris analysis/analytical ferrography.
