Rotating in high speed,
machinery turbines are supported by bearings prevented from grinding against
each other only by thin layers of oil. Such a mechanism is a common sight in
all power plants around the world. In the event that the lubricant
runs out, though, significant damage can occur to the turbine’s bearings due to
the abrupt change in speed. This type of incident calls for months of outage
repairs, impairing production and leading to the loss of millions’ worth of
revenue (especially during demand peaks and spikes).
How long does turbine oil
last, actually? Suppliers would say around 5 to 15 years, but a lot of factors
have to be considered for a more accurate estimate. Aside from operating hours
and maintenance practices, another important variable that determines turbine
oil longevity is oil quality itself. High-grade oil can endure extreme heat for
a longer period of time to inhibit premature wear on turbine parts.
When purchasing turbine
oil, opt for a product that has undergone proper testing and maintenance. Whether it’s a high-temperature gas turbine
system or a combo with integral gearing, choose a lubricant that won’t only
protect your machine from corrosion but which can also minimize the
accumulation of deposits in the bearings and control valves, helping reduce your
equipment’s maintenance and repair.
