530kW motor checks? !!

I've contacted ABB in the hope they can supply full and detailed technical info on the motors, as it's been very difficult to find proper specs about them online, or if their motors were ever reused before and any detailed reinstallation instructions for that.


But this forum has given me lots of checking points to do and that's wonderful.

?‍? It's a great learning school here as these large motors are not something I've ever dealt with before, so again many thanks for all assistance! ?



BUT interestingly downloading their current brochure, it shows the motor bearing system used:


and that shows a 'waste grease box' fitted to the front and rear, so.... as Zoomup mentioned:

'An oil leak or grease leak does not immediately indicate a failed bearing. In fact the grease may have escaped and carried away dirt and metal shavings etc. which is good.'


It could indeed be just an overflowing waste box, as the leakage is mainly localised in one place, certainly at the rearend.


Their brochure also mention locks, that should be set prior to any transportation


It seems they have to be fitted (?) and thus may not be internally already inside the motor which one can then simply lock into a transport safe position. Hopefully ABB can advise on the locks for this motor as there may not be any in the storeroom or that could even be yet another vital part that needs to be salvaged, before someone scraps it!!


Can anyone though advise about large motor cooling - and if IP55 motors were JUST designed to be outside?


I'm wondering with the adverse weather now if plans should be altered to enclose the entire motorpump into a pumphouse?

Hopefully ABB can supply the exact cooling system, but their new motors seem to follow the same format


I'm sure the motor would last far longer if inside but am not sure of the possibly restricted cooling effects of placing the unit inside a building, except ducting or vents could be included I suppose, allowing external outside airflow during operation.


Housed would certainly make maintenance schedules far easier and most importantly non-weather dependant too.

It also would be rather nice to have a pre-warmed pumphouse, for the engineer to then work in!


I'm also wondering now (if they can be housed), if it's better to try and obtain 2 pump units, so one can be the runner with another placed as a standby with necessary pipework gate valves fitted to quickly switch the units over.

Gatevalves could possibly be also salvaged, before any currently onsite were just scrapped.


That setup again would simplify maintenance schedules, as the idle unit can be prepared for reuse and given a proper full complete service (while the main unit runs hopefully happily), and thus means a zero downtime of the main pumpunit if there was only one used.


Interesting.

I'm learning lots!
