BWA-KXE-Fetteinzelstehlager_englisch_02.doc
Maintenance
Structural component Daily Weekly Quarterly Yearly
impeller An inspection of the impeller must be carried out immediately, if
� the permissible limiting values (see chapter 9.1.2 Limiting values vibrations) are
exceeded,
� changed impeller noises occur.
Examine the impeller every 5,000 operating hours and check it for alteration (cracks,
geometric alterations, balancing condition, wear and sticking material), but at least
once a year.
Check the impeller e.g. by non-destructive crack testing.
Fans that are subject to high dynamical stresses are to be checked in accordance with the
additional agreement (maintenance schedule) within the prescribed intervals.
bearings
An inspection of the bearings must be carried out immediately, if
� the permissible limiting values (see chapter 9.1.2 Limiting values vibrations and
9.1.3 Limiting values bearing temperatures) are exceeded,
� changed running noises occur
� unusual alterations of the lubricant occur.
Re-lubrification intervals acc. to plate “Maintenance of the bearings” (see chapt.
7.3.1.2 Lubrication intervals)
shaft seal The shaft sealing rings have to be checked and exchanged if the sealing gas
consumption or leakage increases. Exchange the shaft seal ring when the rings are
worn or damaged. If the seal ring consists of more than one part, replace the full seal
ring set.
shaft earthing Check the correct functioning of the shaft earthing regularly and in dependence of
the operating conditions and replace it, if required.
condensate drain Drain the accumulated condense water in regular intervals or when required in a
suitable drain receptacle and dispose of it in an environmentally compatible way.
coupling If noise levels are changed abruptly and / or vibrations occur abruptly, the coupling
must be checked and if required, it must be re-aligned or exchanged.
