LAKE MAY
PELTON WHEELS
Out of Lee, Massachusetts FRL has acquired three complete Pelton
wheel hydraulic turbines. FRL has since salvaged the equipment out
of the powerhouse and it is sitting by our warehouse. These
machines come with three runners, three pelton cases, six bearings,
six bearing pedestals, three pelton deflectors, three complete
pelton nozzles, three high pressure valves, three high pressure pipe
flanges, two Pelton and one Woodward governors, two induction
generators, and one synchronous generator. The Pelton wheels
are 330 HP at 410 ft of head and at that head they rotate at 600
RPM. The synchronous generator is a Westinghouse, It is 300
kva at a 0.8 power factor. It generates at 2300 volts and turns at
600 RPM. A couple of the coils to this generator are bad but all
the other ones are good. The name plates off the two induction
generators are missing but to the best of our knowledge they are
250KW generators and operate 2300 volts and 600 RPM. The shafts to
the two induction units were cut at the couplings but they are
easily repairable. FRL has a machine shop that can fix these
shafts. All the generator bearings are included. The Pelton buckets
are in excellent condition, with no holes or major pitting. Also a
full set of extra buckets was included. Lastly the original power
house drawing was located. |

Celeste Fay wondering what the
best rigging points are.

The Number Two synchronous
machine. Last run in 1993.

Will standing next to the Number
One asynchronous machine. Last run in 1990.

The number two runner being
loaded to take back to the shop.

Celeste inspecting the Number Two
Unit.

Will Fay has been very busy with
a 30# demolition hammer (rivet buster). It is astonishing how it can remove
hardened/reinforced concrete. The turbine case has been removed. The lower
deflector nozzle still needs to be removed. Note the Pelton waterwheel governor
in background. Note how nice Will kept the area after he was finished each
night.

This is typical of the ongoing
work. Incredible that a 17 year old removed and rigged out this equipment!! Of
course this was the ninth power plant Will had worked on!

No.3 turbine deflector nozzle
being pulled with the overhead monorail. This unit never ran. The plant made
more power with two units running then when all three units ran together. The
penstock was 7000 feet long and the head losses with three units running was too
much. |
