7.1.4 Load-bearing
Bolts
Only greased load-bearing bolts ensure the even swinging of the buckets, and
therefore, the quiet run of the centrifuge. Ungreased bolts can lead to a system
shut-down due to imbalances.
•
Grease the load-bearing bolts of the rotor after each cleaning slightly with
grease for load-bearing bolts (part no. 70284).
7.1.5 Glass
Breakage
•
Glass particles will damage the surface coating (e.g. Eloxal) of the buckets,
which will then lead to corrosion.
•
Glass particles in the rubber cushions of the buckets will cause glass
breakage again.
•
Glass particles on the pivot bearing of the load-bearing bolts prevent the
buckets and carriers from swinging evenly, which will cause an imbalance.
•
Glass particles in the centrifuge chamber will cause metal abrasion due to the
strong air circulation. This metal dust will not only pollute the centrifuge
chamber, rotor, and materials to be centrifuged but also damage the surfaces
of the accessories, rotors, and centrifuge chamber.
In the case of glass breakage, immediately remove all glass particles (e.g.
with a vacuum cleaner).
Replace the rubber cushions since even thorough
cleaning will not remove all glass particles.
In order to completely remove the glass particles and the metal dust from the
rotor chamber:
•
Grease the upper third of the centrifuge chamber with e.g. Vaseline.
•
Then, let the rotor rotate for a few minutes at a moderate speed (approx.
2,000 rpm). The glass and metal particles will now collect at the greased part
and can easily be removed with a cloth together with the grease.
•
Remove the grease with glass and metal particles with a cloth.
•
If necessary, repeat this procedure.
