Summer Maintenance Checklist

Summertime is almost here!  That means summer run season is beginning and many turbine generator sets will be in operation over these next few months.  While the units are in operation that provides facilities with the opportunity check some items off of the to-do list.  We offer a variety of non-turbine outage services during the summer months.  Please see our common summer services below and let us know if there is anything we can help you accomplish.

Wind Turbine Shaft Machining

 

We recently received a call to perform an uptower repair of a damaged shaft inside a Wind Turbine.  We have experienced technicians that are specifically trained for uptower Wind Turbine repairs, and have the expertise and equipment to successfully execute these projects.  The final results are a safe, quality project – with a shaft that is back within OEM specified tolerances.  The photos below show the before and after of a shaft in need of refurbishment, and the excellent work that our technicians perform.  The end result is another satisfied customer…

Shaft Machining

Our Field Machining Division was dispatched to repair an inboard fan shaft for a Utility customer in the Midwest.  We mobilized a total of 4 specialty field machining personnel, and began the process of machining the inboard fan shaft which had severe shaft damage and hard spots.  We cleaned up 100% of the shaft, had hardness checks performed, and then proceeded to final hone and polish.

The total duration of the project was 3 days from start to finish, and the end result was another satisfied customer.  The photos below will give you an idea of the severity of the original shaft damage, as well as the final condition upon completion.  Another great project by our Field Machining Division!

Collector Ring Machining

 

During any turbine generator outage season we often receive an influx of calls to perform collector ring machining on various makes and models of generators.  It is critical to maintain as much brush to collector ring contact as possible, and machining the rings can make sure the surface is free from defects that may inhibit brush to ring contact.  The need for this machining is typically determined after the generator has been disassembled and inspected, making this service an emergent repair that needs to be performed within a time-sensitive window.  When these requests are received we typically request basic dimensional data and then provide a quick quotation for services.  Once approved, we immediately dispatch our qualified technicians to site along with specialized machining equipment.  This work is typically completed in 1-2 shifts, and the customer is able to continue forward without this service having any impact on the overall schedule.

Bearing Saddle Machining

 

We were recently called into a power plant to machine out damage present in a bearing saddle.  This required the use of specialized machining equipment (photo of equipment being set up shown below), as well as highly skilled Field Machinists to operate the equipment, and maintain extremely critical tolerances in final machining.  Very nice job by our Field Machinists, and another example of our critical machining capabilities.
