Страница: 13 / 16

WARNING:
Ensure the Sterimixer/Sanimixer is in a
safe state before performing any service.
Before performing maintenance and service ensure;
• the impeller and vessel are fully cleaned from any
process fluid and that no process fluid can enter the
vessel during maintenance.
• the vessel is fully vented from any possible gases.
• the vessel is depressurised.
• the main power is switched-off and cannot be acci-
dentally switched on during maintenance.
• the vessel has been cooled to a temperature below
50
◦
C (or a limit set by local regulations).
5.1. Routine maintenance during start up/running in
Following maintenance schedule should be performed at
start up and/or running in of the Sterimixer/Sanimixer.
• Remove and check the impeller.
• If particles are stuck to the impeller they have to be
removed.
• Due to the strong magnets inside the impeller all
magnetic particles will get stuck inside the impeller.
Therefore, check the inside of the impeller in particu-
lar.
• The impeller must not be scratched or in any way
damaged. If it has been damaged, the impeller and
bearing must be replaced. The impeller can be sent
to Steridose for refurbishment.
5.1.1. At least once a year - interval dependent on appli-
cation
The following maintenance schedule should be performed
at least once a year. Note that the interval will be highly
dependant on the application.
• Remove and check the bearing and the impeller for
signs of surface damage and general wear of the bear-
ings.
• Change the bearing and the impeller if the surface
is coarse or uneven, scratched or if fragments have
been knocked out from the bearing. The impeller can
be sent to Steridose for refurbishment.
• Change the PTFE washer when dismounting the bear-
ing.
• Make a general inspection of the motor, gearbox and
other Sterimixer/Sanimixer parts. Make sure the
gearbox is not leaking oil.
• ATEX application specific advice can be found in sec-
tion 4.7
5.1.2. General guidelines on bearing wear
Actual wear of the impeller bearing and the male bearing
unit will depend on the application. Impeller bearings
can in many cases be replaced as part of an impeller re-
furbishment. This refurbishment can only be done at the
Steridose factory or authorized Steridose service center.
Male bearing units cannot refurbished, they must be re-
placed when worn.
The outline of a bearing wear assessment is as follows:
1. Measure the inner diameter of the impeller bearing,
ID =
2. Measure the outer diamater of the male bearing unit,
OD =
3. Calculate the difference ID − OD = and check that
the difference does not exceed 0.14 mm. If the mea-
sured value exceeds the 0.14 mm, send in your im-
peller and bearing unit in for evaluation and repair.
