Wynoochee Hydro Mechanical Repairs Fall 2014 to Spring 2015

During a recent attempt to eliminate a tenacious oil leak on the turbine generator at Wynoochee, a number of problems were discovered and repaired. These included failed welds inside the generator support structure, a failed rubber turbine guide bearing, a damaged turbine shaft seal, silt plugs inside the heat exchangers and drain lines, and a worn generator shaft support that allowed the shaft to swing like a pendulum. The 15 megawatt Wynoochee Electosila Generator and LMZ turbine, which were purchased shortly after the fall of the Soviet Union, were installed in 1994.

The 40,000 pound upper bracket with the broken welds was removed and sent to Thompson Metal Fabrication. They ground out the damaged welds, replaced them and baked the piece in a large oven to relieve any stresses. It was subsequently, shipped to A.F. Dick Machine shop to have its surfaces trued up, sandblasted and receive a new coat of paint.

Fortunately, a new rubber bearing that had been preserved for 20 years was located in the Wynoochee store house. The old bearing was removed and the new bearing was installed.

The fretted, copper interference rings that supported the generator shaft were replaced with new bronze rings.

Tacoma Power hired HCMS a contractor that specializes in hydro generator work, to re-assemble and balance the unit. They worked closely with Tacoma Engineers, Cushman staff and NAES mechanics to assemble the unit. After the assembly was completed an attempt to balance the unit was made. The assembly team did such a great job that the unit was deemed balanced without the addition of balance weights. The unit was restored to service March 19.

FIGURE 2. The 35,000 pound bracket sits on the 20-foot diameter turntable at A.F. Dick Manufacturing Machine Shop in Astoria, OR (Contact Art Dick at 503-458-6292). Art Dick was awesome and allowed our bracket to be slipped in the schedule between an order for rocket bodies for NASA and a giant hydro generator shaft from CA.

Figure 3. A chilling effect: The bronze interference ring is cooled with dry ice to shrink fit for installation.

Figure 5. Inserting the sub chilled bronze rings into the thrust block.

Figure 6. Machining the vertical keyway through the surface of the new bronze interference rings with a large shaper. The interference fit of the bronze ring in the steel thrust block is 0.009 inches. The bore of the block was subsequently machined on the Betz Boring Mill to a o.oo3 interference fit between the bronze bore and the steel generator shaft.
