Oil Sampling Best Practices (Part 2)

Posted by Augustus Kaskons

Bottles

Sampling bottles come in many shapes and sizes. 120 ml (4 oz) HDPE (opaque) bottles have been the most common sampling bottle for many years. Many suppliers now provide clear PET, or PS bottles for oil sampling so end users can readily see debris or water in the sample, forcing a resample before sending it over to the testing area, or outside service provider.

Oil Sampling Best Practices

Posted by Augustus Kaskons

Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These access sampling points make it easier for operators to quickly and easily take representative oil samples.

Automated Oil Particle Analysis Helps Prevent Gearbox Failures

Posted by Augustus Kaskons

The major issue for premature failure in wind turbine gearboxes is bearing failure, which leads to gearbox failure. A wind turbine gearbox will not survive if the oil is not clean and especially if the hard ferrous particles are not removed from around the bearings.

Guide To Coolant In Oil Test Methods

Posted by Augustus Kaskons

Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, leading to formation of glycolic acids. These acids attack nonferrous bearing surfaces and form metal salts. The acids also react with the oil anti wear and anti oxidant additives and, along with water, create sludges that plug filters and cause the oil to lose its lubricity properties, thus increasing abrasive wear. Glycol contamination in engines and transmissions is considered to be a more severe contaminant than water alone (up to 10 times more damaging). Depending on the oil temperature, the glycol coolant may break down rapidly, or over time. This instability is a major challenge for determining the true glycol content in the oil at a given time, and is the major reason why field and lab tests often do not agree with each other.

Case Studies Show Benefit of On-Site Oil Analysis

Posted by Augustus Kaskons

On-site oil analysis pays off for fleet maintenance

Fleets use on-site oil analysis to reduce downtime and save money. This article highlights several different fleets including a municipal utilities fleet, a sheriff's fleet, a sanitation fleet and a city fleet, and how oil analysis benefits their maintenance activities. One of the biggest costs for the municipal utilities fleet was the labor cost associated with performing the oil changes. Safely extending oil change intervals saved them enough money to pay off the cost of the on-site oil analysis equipment in two years.  

For the sheriff's fleet, the biggest cost was the cost of having law enforcement officers not out on the road doing their jobs. Bringing a vehicle in for an oil change often required paying officers overtime and took away from their more important activities. Extending oil change intervals saved on this cost.

Fast, accurate total ferrous measurement

Posted by Augustus Kaskons

The measurement and trending of abnormal ferrous wear debris in machinery lubrication oils is arguably the most significant indicator of machinery health and a key predictor of catastrophic machinery failure. There are several methods available to measure the ferrous content of lubrication oil.

Guide to Measuring Biofuel Blending

Posted by Augustus Kaskons

As the global commitment to renewable energy sources grows, the importance of using biodiesel as a blending component with diesel fuel has increased. Biodiesel consists of fatty acid methyl esters (FAME) which are produced by the transesterification of certain feedstock oils, such as soy, rapeseed, canola, and others. The biodiesel is then blended with diesel fuel at amounts required by the regulatory agencies of different countries. It is important for fuel terminals and distributors, as well as regulatory agencies, to check the concentration of biodiesel in the diesel fuel in order to make sure it is within these allowable limits. Diesel fuel with too little biodiesel will not meet renewable fuel standards and fuel with too much biodiesel may cause engine failures.

Techniques for Soot in Oil Analysis

Posted by Augustus Kaskons


Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and become more dangerous. The soot levels will continue to increase and the particles clump together until it reaches a level great enough to precipitate out of the oil. This precipitation will both increase the viscosity of the oil and attach itself to the engine surfaces which will significantly increase wear on the engine. This precipitation can also lead to filter plugging. Performing regular soot checks can realize cost savings by extending drain periods, reducing used oil disposal, and extending the life of diesel engines.
