3. Check the oil level in the gear unit of the Börger machine.
On standing versions, the oil level must reach at least
halfway up the oil sight glass. If this is not the case, the gear
oil (cf. data sheet) must be refilled, see
Ä
Chapter 6.2.2
“Lubricant fill level and changing the lubricants” on page 116.
4. Ensure that the breather system at the gear unit is properly
installed.
5. Ensure that the breather at the intermediate chamber is
properly installed and the quench fluid can drain of
f freely in
the event of a seal leakage, or, when no medium must be
released into the atmosphere, that a suitable drain system is
installed.
NOTE!
The quench fluid is used for monitoring the integrity of the
mechanical seals, and also for protection, lubrication and
cooling of the mechanical seals, see
Ä
Chapter 3.1.5 “Shaft
seal” on page 40 and
Ä
Chapter 3.1.6 “Intermediate
chamber (quench)” on page 41.
6. Check whether the delivered quench fluid (see enclosed
data sheet) is suitable or whether an alternative fluid must be
used in order to observe environmental protection regula-
tions, or for biological or other reasons. This must be compat-
ible with the medium, and must not adversely affect the O-
rings of the mechanical seals. Consult Börger GmbH
regarding this, if necessary.
7. Check the fill level in the intermediate chamber. On
standing versions, the quench fluid must reach halfway up
the top shaft. Otherwise, the quench fluid (cf. data sheet)
must be refilled. If there is much more fluid in the inter-
mediate chamber than the optimum fill level when the
mechanical seal is intact, some of the fluid should be drained
of
f in order to prevent premature overflowing. Otherwise, the
functionality of the leak monitor may be compromised. In this
regard, also see
Ä
Chapter 6.2.2 “Lubricant fill level and
changing the lubricants” on page 116.
8. Check that the coupling guard or the V
-belt or chain guard
is positioned correctly and fixed securely.
