Öljynäyteanalyysi

Öljynäyteanalyysi, also known as oil analysis, is a diagnostic technique used to assess the condition of lubricants and the machinery they are lubricating. By taking a small sample of used oil from a piece of equipment and subjecting it to various laboratory tests, valuable information can be gathered about the lubricant's performance and the internal health of the machine.

The primary goals of oil analysis are to detect potential problems before they lead to catastrophic equipment failure, to optimize maintenance schedules, and to extend the service life of both the oil and the machinery. This proactive approach can significantly reduce maintenance costs and downtime.

Key parameters analyzed typically include physical properties such as viscosity, color, and water content, as well as chemical properties like additive depletion and the presence of contaminants. Spectrometric analysis can identify wear metals, which indicate which components within the machine are showing signs of abrasion or damage. Elemental analysis can also detect the presence of foreign materials like dirt, dust, or coolant.

The interpretation of oil analysis results requires expertise. Technicians compare the findings against established normal ranges and historical data for the specific equipment and lubricant type. Trends over time are particularly important, as a gradual increase in wear metals or a decrease in additive concentration can signal an impending issue.

Oil analysis is widely applied in various industries, including manufacturing, transportation, power generation, and mining. It is a cost-effective and efficient method for predictive maintenance, contributing to improved reliability and operational efficiency.
