Stationary Blade Restoration

During the most recent outage season, PSG was contracted to perform the in-place restoration of stationary blades on an 800MW Steam Turbine for a large power producer in the United States.  The customer was looking for a solution where the blades could be restored without completely disassembling the unit and sending the components to a shop – enabling them to save valuable generation time and significant expense.  Our Field Machining Division mobilized our specialized technicians and equipment and began the detailed process of restoring the blades, ultimately returning them to operating specifications.

The customer was extremely pleased with the outcome of the project and commented on the high-quality craftsmanship displayed by our technicians.  This is another example of the complicated turbine repairs we can perform on-site, and a testament to the quality of our execution personnel.

Measure the Cause, Not the Symptom

Directly measuring bearing metal temperature is the most effective way to really determine if a bearing is running hot. Bearing oil drain temperatures are still being utilized on older machines. By the time the bearing oil drain temperature has increased, the bearing may have already been compromised (wiped). PSG recommends that these older machines should have temperature probes (thermocouples or RTD’s) installed in the bearing Babbitt to properly monitor performance. A two-level alarm is recommended (not automatic trip). The first alarm should be set a few degrees above the highest temperature in the recommended normal operating range. Operators should closely monitor bearing temperature after the first alarm sounds. If the temperature rises abruptly and unexpectedly, the bearing may have been compromised and immediate action needs to be taken. Gradual temperature changes which trigger the alarm may be the result of other factors but are still a concern and should be thoroughly investigated. The second alarm should be set at the maximum operating temperature of the bearing material. Operators should manually trip the unit in a controlled manner as soon as possible after this second alarm sounds and determine the cause. The critical temperatures for each of the two levels can be supplied by the manufacturer or recommended by PSG for your individual unit configuration. Different temperature ranges are recommended for Tilt Pad, Elliptical, Short Elliptical and Thrust bearings. Measuring drain oil temperature is too slow and too imprecise to effectively minimize your overall cost of maintenance. Retrofit your machine and save your bottom line.

Spill Strip Installation

We are in the process of installing new spill strips for an industrial GE Steam Turbine. Very nice work by our Steam Path Repair facility in Pevely, Missouri.

69th Annual AREGC Conference

We are at the 69th Annual AREGC Conference in Lanier Islands, Georgia this week.  Please stop by and visit us if you are attending.  This year’s conference is being hosted by Oglethorpe Power Corporation.  Thank you to all those who organized the event!

New 1st Stage Bucket Installation

PSG’s Steam Path Repair Facility, located just outside of St. Louis, Missouri, has been busy this spring.  One of the many projects we executed last month was the installation of new 1st stage buckets on an industrial GE Steam Turbine.  The time and precision it takes to successfully install these buckets is extremely impressive.  The meticulous attention to detail by our trained technicians allowed us to complete the installation safely, on-time, and with the highest level of quality.  Great work team!

2018 Frame 6 User’s Group Conference

We look forward to seeing everyone at this year’s Frame 6 Users Group Conference in Ponte Vedra Beach, Florida! It should be another fun event. Please stop by Power Services Group at Booth #13 during the Vendor Trade Show. Safe travels and see you next week!

 

CPS Energy tees off United Way campaign to support SAMMinistries

Great work by everyone that made this possible. PSG is proud to have been part of this event and the good that it has done for the San Antonio community. The volunteers that make all of this happen are amazing individuals, thank you!

PSG is equipped and ready to tackle your Journal and Shaft Machining Projects

Power Services Group’s field machining division, Orbital Energy Services, has successfully repaired thousands of shafts and bearing journals in power and industrial facilities across the globe over the past 20 years. Our unique, on-site machining process requires absolutely no need for shaft rotation, and avoids the issues related to removing and shipping equipment to a shop: costly mobilizations, exorbitant shipping costs, potential damage during shipment, valuable lay down space, and plant crane and rigging requirements. Orbital Energy Services’ finely tuned and safe processes coupled with a full range of equipment ensure customers receive the highest quality at a competitive price. If you have a journal or shaft machining project, planned or an emergency, please contact us anytime for a fast response.
