Power Plants
Power generating plants with inadequate maintenance programs will invariably be unable to compete in today’s very competitive industry. For this reason, power plants are implementing a variety of technologies to reduce the costs of maintenance and to increase plant reliability and efficiency.
Oil analysis can be a very effective tool in determining its condition. Even though the primary focus should be on monitoring for wear, determining the condition of the oil through analysis is still important. By analyzing the oil it is possible to establish the oil’s condition and its ability to continue protecting the equipment. An oil analysis program will indicate any changes in viscosity, oxidation and depletion of additives in the oil. It will also show if any contaminants are present.
Lubricating oil contamination is a major problem and if not controlled can lead to catastrophic failures of power plant equipment. Some of the contaminants in lubricating oils include gases, liquids such as water, and solid particulates. Gases decrease viscosity and promote foaming that in turn reduces the lubricating properties of the oil
To minimize undesirable properties in the oil, additives are often used. Antioxidant additives are added to increase the life and storage of oils, while antifoam additives help to reduce foaming. Other additives include: anti-wear, extreme pressure, pour point depressants, corrosion and rust inhibitors, de-mulsifiers, detergents and dispersants.
Varnish Potential Analysis
Varnish is an insoluble film that coats the internal components of machinery lubrication systems. The specific lubricant degradation byproducts associated with varnish formation remain elusive so is the need for the special test for finding the VPI ( Varnish Potential Index).

To increase power plant efficiency, Triple R products are used in plants that generate their power from fossil, nuclear, and renewable sources. Power customers around the world rely on Triple R to provide products that will maintain clean oil and fluids consistently, reliably, and economically.
What this means to you is simple; power plant efficiency.
To help insure power plant efficiency, Triple R provides depth filters, vacuum filters, and centrifuges to maintain oil in hydraulic systems, pulverizers, steam turbines, power transformers and other power generation equipment.
Maintaining power plant efficiency can be difficult; operating conditions for hydraulics and other fluid systems in power stations are harsh. Contamination, dust and moisture in pulverizers have a serious negative impact on gear oil.
Oil undergoes rapid oxidation and and induces corrosion of bearings as a result of steam/water and contamination. The insulation efficiency of transformer oil is reduced due to water and gases.
Triple R has the knowledge and experience to prevent equipment failures due to water and contamination effects, helping maintain power plant efficiency.
For companies renting power generator sets all over industry, efficient and cost effective maintenance isn’t easy to achieve. Equipment failures due to water and excessive contamination are common.
But Triple R offers a series of filtration systems that assure perfectly clean OIL and FUEL cleanliness. Thanks to Triple R oil changes can be extended from 400-500 hrs up to 2.000 hrs. Ask your Triple R representative for further details.
