When it comes to maintaining hydraulic systems, many operators focus on pressure levels, temperature ranges, and fluid properties. However, one critical factor often overlooked is oil cleanliness. NAS 7, a specific classification under the NAS 1638 cleanliness standard, provides a benchmark for controlling particle contamination in hydraulic fluids. This article explores how NAS 7 cleanliness enhances system reliability and how Sinopec’s hydraulic oils help you achieve it effortlessly.
Breaking Down NAS 7 Cleanliness
NAS 7 refers to a cleanliness level in the NAS 1638 standard, which measures and categorizes contamination in hydraulic oil based on particle size. It limits the number of particles per 100 milliliters of fluid, ensuring hydraulic systems remain free from harmful debris that could compromise functionality.
For example, under NAS 7, the number of particles sized between 5-15 µm is capped at 32,000, while particles larger than 100 µm are limited to 32. Adhering to these standards ensures smooth operation and reduces risks associated with contamination.
The Impact of Clean Hydraulic Oil on Performance
Hydraulic systems are highly sensitive to impurities. Even small particles can:
-
Erode components: Leading to leaks and loss of efficiency.
-
Increase friction: Causing higher energy consumption and overheating.
-
Clog filters: Leading to reduced flow and unexpected breakdowns.
By maintaining NAS 7 cleanliness levels, you ensure:
-
Prolonged Component Life: Fewer contaminants mean less wear and tear.
-
Reduced Operational Costs: Lower repair expenses and downtime.
-
Enhanced Efficiency: Smooth operation with minimal resistance.
