09 – Functions of lubricant. Cooling

In this video, we will delve into another of the functions of lubricant and how it is improved when
moving from oil level to oil mist lubrication.

We analyze in detail the function of cooling or removing heat. The differences between both lubrication
methods are notable, as far as the function of removing heat is concerned. In the oil bath or level, there
is the problem that part of the machine’s power must be used to “move” the oil in a liquid state. The
dissipation of this heat is slow. When oil mist lubrication is applied, and the need for the oil bath is
eliminated, liquid friction is directly eliminated. If, in addition, we consider that the oil mist enters the
system between 16 and 20 Celsius degrees of temperature; a better effect of dissipation of the
generated heat is also produced. These two effects result in temperature decreases of 10 °C on average,
and energy savings when moving from oil level to mist lubrication.

HIGH EFFICIENCY FILTRATION OF A COMBINED CYCLE GAS TURBINE IN CATALONIA

At the end of October, Sicelub Ibérico, our company in Spain, carried out an intervention in an important Combined Cycle Power Plant in Catalonia. We intervened on a gas turbine.

We drained the lubricating oil from the main tank, approximately 23,000 liters, into an external tank, where a high efficiency filtration is carried out, while a mechanical cleaning of the tank is carried out, considered a Confined Space. It is important to indicate that during the cleaning we found tools inside the tank (see photo).

Once the cleaning of the tank was completed, and having the approval of the owner, the oil is loaded again under filtration; until reaching the appropriate ISO cleaning code.

A 320 lt/min filtration system was used with 34” long filter elements and β1›1000 (filtration efficiency of 99.9% for particles larger than 1 micron).

It can be seen in the ISO 4406 Code evolution curve how the lubricant cleanliness level was improved from ISO 19/18/14 to ISO 14/13/11. This means that the lubricant oil is delivered with 30 times less particle content. This feature provides a greater probability of correct operation of the turbine, and a longer expected life of the lubricant.

It is also very important to highlight that, due to the Meteorological Alert, we had to change the return route of our technicians, to avoid any risk.

We would like to thank our clients, our suppliers, and our staff for their trust in us, in providing a quality, safe, and environmentally friendly service.

08 – Lubricant Functions. Particle Removal.

In this video, we are going to delve into another of the lubricant’s functions and how it is improved by moving from oil level to oil mist lubrication.

We analyze in detail the function of removing particles. When we have an oil bath, it is easy to notice that any dirt or wear particles present will remain suspended in the oil bath, and there is no possibility of them being eliminated. The presence of these particles will cause abrasive wear of the bearings. In the case of oil mist lubrication, since there is a permanent flow of oil mist entering and leaving the system, it is easy to notice that any dirt or wear particles present will be expelled outside the tribological contact zone. A common example is to compare the situation of taking a daily immersion bath, always using the same water, which periodically becomes dirty; with the situation of changing the above for a fresh shower with clean water, a situation that is undoubtedly much more effective and common.

The process that would be quite strange for a daily personal hygiene situation; It is widely accepted in the industry when it comes to bearing lubrication. Undoubtedly, an opportunity for significant improvement.
