The aviation, industrial, and mobile industry sectors utilize hydraulic systems to deliver power to equipment on a consistent basis. These are compact, efficient, and lightweight systems. Hydraulic fluids are used in systems such as these as well. Fire points, high flash, viscosity, and chemical stability as well as oxidation resistance are valued and as a result mineral and synthetic hydrocarbon are the prime choice for industrial and mobile applications. While in industrial and aviation applications, phosphate esters and other functional chemicals are utilized. Many businesses can benefit from hydraulic oil analysis services. Minneapolis, MN is served by companies that can provide these high-value services.
Performance Evaluation With Oil Analysis
The way to determine if hydraulic fluid is deterred from expected performances is through the monitoring employed by hydraulic oil analysis services. Failures caused by contamination – either dirt ingression, water contamination, or both. Filters on hydraulic systems as well as systematic monitoring can help identify signs of contamination and wear. They can also help determine how successful the filtration system is operating.
When evaluating system cleanliness, the manufactures of hydraulic systems identify what specific ISO code should be used. For example a 20/18/15 ISO code may be applied to hydraulic system pump. On the other hand, in 18/16/13 ISO code may be applied to actuator and valve.
There tight tolerances used in hydraulic systems. For instance servo valves utilize tolerances of 40 to 80 µm. Actuators may utilize tolerances as low as 10 µm. Particles greater in size than 4 µm may introduce problems into hydraulic systems. Measuring particles in hydraulic systems is governed by a number of documents, including SAE guidelines, ASTM methods, and ISO codes. These techniques and/or codes generally identify particles based on concentration and size.
Water is a contaminant found often in hydraulic systems – it can lead to oxidation and corrosion of hydraulic fluid. The contamination level of water should be kept beneath 2500 ppm.
Additional parameters to monitor include total acid number, kinematic viscosity, particle counting, wear debris analysis/analytical ferrography, oxidation by infrared analysis, and elemental spectroscopy.
