Rotating machinery Oil Analysis

LBE_Website_III_03_Gas turbine researchLaborelec provides oil condition monitoring services for rotating machines. Trending the analyses of the lubricating oils to get an accurate view of both the condition of the oil and the machinery.

Lubricating and hydraulic oil quality assessment

Checking the functionalities of oils for rotating machinery

Laborelec trends the quality of lubricating and hydraulic oils in service to assess to what extent these oils still retain their functional properties (lubrication, heat exchange, corrosion protection, and elimination of internal contamination).

Lubricating oil expert advice

To determine that oils remain within OEM or industry maintenance specifications (for instance ASTM D4378). To prevent sludging, varnishing, and corrosion as well as machinery wear due to insufficient lubrication. To avoid unforeseen maintenance costs and shut downs.

If certain parameters prove to be insufficient, our experts determine the most appropriate maintenance actions or oil bath replacement.

Machinery Lubrication Oil Training

Specific training courses (on-site or at Laborelec) to help customers increase their knowledge of important aspects of oil analyses,  analytical techniques, and interpretation of data.

Training: Monitoring the condition of rotating machines through regular oil analyses

List of Rotating Machinery oil tests

The determination of acidity is a basic analysis for trending ageing in turbine and hydraulic oils. The MPC or VPI test allows to assess the risk on varnish formation in degraded oil circuit.
