FEB 2006 as reported by Mark Dye
P6001A P6001B P6003A N East firewater pond West firewater pond P6003B P6002B P6002A East isolation gate West isolation gate Pump house layout
This is the pumps hydraulic end With the pump submerged, the water flows up through the shaft housing
The business end !
The pump and first pipe spool being lowered into the well…
…into the icy water below
Looking down through the spool to the pump top below
A shaft bearing is installed between each pipe spool and clamped between the flanges The bearing is water lubricated and made of PTFE
The shaft joining piece has a left hand thread! The next pipe spool is lowered into position
The flanges are bolted together, then torqued down to 175 ft-lbs. The support is opened, and the pump is lowered.
With all the parts assembled we have… The pump at approx 2.5 metres Three spools at 1.7 metres each One spool at 1 metre Giving a total of 8.6 metres Now we need the stuffing box assembly
The stuffing box assembly is unpacked, And the top bearing assembly removed.
The top bearing assembly is keyed to the shaft because it also contains a ratchet device to prevent back turning of the shaft.
STEADY AS SHE GOES!!!
Thread the shaft through and line up the spool bolts. The whole assembly now needs to be lifted to remove the spool support. The combined weight is now 3.7 tonnes.
The top bearing is re-installed and keyed to the shaft.
The coupling housing and motor stand installed. The coolingwater supply, …and return, and constant level oiler is fitted.
