Landfill gas engine analysis
This service monitors engine and lubricant conditions to detect premature wear and contamination
Description
Landfill gas presents a unique set of challenges for engines; early detection of premature engine wear, coolant leaks and lubricant contamination is necessary for continued operation. This analysis helps you discover these issues before they can result in costly downtime or expensive repairs.
Test | Purpose | Importance of test |
---|---|---|
Chlorine | To determine the level of chlorine contamination | Chlorine from landfill chlorinated fluorocarbons, in conjunction with moisture, can cause excessive metal corrosion |
Coolant Indicator | To determine the level of sodium, potassium and boron in the compressor oil | Indicative of a coolant leak into the compressor |
Metals | To determine the presence and levels of metallic content in the oil, including contaminants and wear particles | The level of metals helps determine if equipment components are wearing or if harmful contamination is entering the oil. The level of metals that are part of the additive chemistry are also reported |
Nitration | To measure the amount of nitrogen by-products in hydraulic oil | In high-pressure pumps, nitration results from the rapid compression of entrained air. As a result, if unchecked, nitrogen and oxidation precursors might form sticky varnishes, which may lead to valve sticking |
Oxidation | To determine the level of lubricant oxidation and deterioration |
Oxidation can mean:
|
Particle Qualification (PQ) Index | To determine ferrous metal fatigue failures and metal-to-metal contact not usually detectable with some spectrographic analysis |
PQ Index can detect at an early stage:
|
Total Acid Number (TAN) | To measure acidic oil oxidation by-products | An elevated Total Acid Number may indicate increased oil acidity resulting from increased oil oxidation |
Ultra Centrifuge | To measure varnish deposit formation in hydraulic oil | Elevated deposit formation can indicate potential for varnish formation |
Viscosity | To determine the oil’s resistance to flow |
|
Water | To detect presence of water contamination | Water contamination may cause severe corrosion and subsequent wear, poor oil film thickness or hydrogen embrittlement |
