urbine and the condenser. Also open the drains from
the steam strainer, etc. This will considerably reduce the time the
turbine requires to come to rest. Still more time may be saved by
leaving the field current on the generator.

Care should be taken, when the vacuum falls and the turbine slows down,
to see that the water is shut off from the glands for fear it may leak
out to such an extent as to let the water into the bearings and impair
the lubricating qualities of the oil.

Inspection

At regular intervals thorough inspection should be made of all parts of
the turbine. As often as it appears necessary from the temperature of
the oil, depending on the quality of the oil and the use of the turbine,
remove the oil-cooling coil and clean it both on the inside and outside
as previously directed; also clean out the chamber in which it is kept.
Put in a fresh supply of oil. This need not necessarily be new, but may
be oil that has been in use before but has been filtered. We recommend
that an oil filter be kept for this purpose. Entirely new oil need only
be put into the turbine when the old oil shows marked deterioration.
With a first-class oil this will probably be a very infrequent
necessity, as some new oil has to be put in from time to time to make up
the losses from leakage and waste.

Clean out the oil strainer, blowing steam through the wire gauze to
remove any accumulation of dirt. Every six months to a year take off the
bearing covers, remove the bearings, and take them apart and clean out
thoroughly. Even the best oil will deposit more or less solid matter
upon hot surfaces in time, which will tend to prevent the free
circulation of the oil through the bearings and effectively stop the
cushioning effect on the bearings. Take apart the main and secondary
valves and clean thoroughly, seeing that all parts are in good working
order. Clean and inspect the governor and the valve-gear, wiping out any
accumulation of oil and dirt that may appear. Be sure to clean out the
drains from the glands so that any water that may pass out of them will
run off freely and will not get into the bearings.

At the end of the first three months, and after that about once a year,
take off the cylinder cover and remove the spindle. When the turbine is
first started up, there is very apt to be considerable foreign matter
come over in the steam, such as balls of red lead or small pieces of
gasket too small to be stopped by the str
