Medium & High Speed Engine Maintenance & Monitoring Equipment Significantly Reduces Downtime
Reduce Downtime in Medium and High Speed Engine with Maintenance and Monitoring Equipment
Medium and High Speed Engines operating on residual fuel are among the most demanding of applications for lubricants.
The oil in Medium and High Speed Diesel Engines experience a greater stress than that in a 2 Stroke Engines. It must lubricate the bearings and pistons, keep them clean, cool under the piston crown and also protect the liner and rings from acidic combustion gasses. During this process, it is consumed and replaced with new oil top up. The Directory of Bearing Failures illustrates what can happen if a sufficient oil analysis programme is not implemented in Medium Speed Engines and High Speed Engines.
Total Base Number (TBN)
Monitoring oil consumption rates have been reducing, both as a mechanism to control fouling around the rings and piston crown and also to control hydrocarbon and particulates emissions in the exhaust. This reduces the amount of new oil top up and increases the rate at which the TBN will deplete. Very low oil consumption engines operated on high sulphur fuel can experience an oil life of less than 1000 hours (more similar to land fill fuelled gas engines). Monitoring the TBN in Medium and High Speed Engines and using a high BN oil is proven to greatly reduce the cost of lubrication under these circumstances, as exemplified by one customer operating a cement plant in India and using our equipment for this purpose. TBN can be tested using the Kittiwake Electronic TBN Test or the DIGI TBN Test Kit
Water in Oil & Insolubles Monitoring in Medium and High Speed Engines
After TBN depletion, the most common problem is water followed by insolubles. A rapid rise in insolubles is indicative of combustion problems. A rise in either should be investigated before the alarm limit is reached and the oil condemned.
Viscosity Testing in Medium and High Speed Engines
High Speed Engines and Medium Speed Engcan additionally experience dilution of the oil from distillate fuel. The fuel enters either via leakage at the fuel pumps or through combustion problems. Kittiwake viscosity tests are very sensitive to fuel dilution and can detect a very low contamination level. Viscosity is also affected by top up with the incorrect oil grade.
Ferrous Wear Debris Testing in Medium and High Speed Engines
Testing for ferrous wear debris often highlights the earliest visible onset of failure. Worn engine parts will leave trace particles in the oil which when trended using simple onsite test equipment will provide extremely useful data that helps save your critical plant.
Other tests which are commonly carried out on Medium Speed Diesel Engines and High Speed Diesel Engines:
