Flushing the Vacuum Pump
WARNING
_ad
Degraded oil can choke pipes and coolers.
Risk of damage to the vacuum pump due to insufficient lubrica-
tion.
Risk of explosion due to overheating.
If there is a suspicion that deposits have gathered inside the
vacuum pump the vacuum pump shall be flushed.
Make sure that all the used oil is drained
Create 0.1 litre(s) (RB 0006 C) or 0.2 litre(s) (RB 0006 E) resp.
flushing agent from 50 percent oil and 50 percent paraffin or diesel
fuel/fuel oil
Make sure that the sight glass (g) is firmly inserted
Remove the filling plug (b)
Fill in the flushing agent
Firmly reinsert the filling plug (b)
Close the suction line
Run the vacuum pump for at least half an hour
Drain the flushing agent and dispose of it in compliance with appli-
cable regulations
Note
: Due to the use of paraffin and even more in case of using diesel
fuel/fuel oil, an unpleasant odour can occur after recommissioning. If
this is a problem, diesel fuel/fuel oil should be avoided and the vacuum
pump be run at idle in a suitable place until the unpleasant odour
vanishes.
Filling in Fresh Oil
Note
: In case the exhaust filter is yet to be removed, fill in fresh oil only
after the exhaust filter is in place again.
Keep 0.1 litre(s) (RB 0006 C) or 0.2 litre(s) (RB 0006 E) resp. oil
acc. to the table Oil (
page 17) ready
Note
: The amount given in these operating instructions is a guide. The
sight glass (g) indicates the actual amount to be filled in.
Make sure that the sight glass (g) is firmly inserted
CAUTION
_a
Filling oil through the suction connection (c) will result in breakage
of the vanes and destruction of the vacuum pump.
Oil may be filled through the filling port (b) only.
Remove the filling plug (b)
Fill in approx. 0.1 litre(s) (RB 0006 C) or 0.2 litre(s) (RB 0006
E) resp. of oil
Make sure that the level is between the MIN and the MAX-mark-
ings of the sight glass (g)
Make sure that the seal ring is inserted into the filling plug (b) and
undamaged, if necessary replace the filling plug (b)
Firmly reinsert the filling plug (b) together with the seal ring
Exhaust Filter
Checks during Operation
Make sure that the vacuum pump is running
Check that the drive motor current drawn is in the usual range
Version with oil return valve (RB 0006 C/E):
Note
: The discharged gas will also contain oil if the vacuum pump is
operated without interruption for too long a period (
page 7: Opera-
tion Notes).
Check that the discharged gas is free from oil
Assessment
If
the drive motor draws too much current and/or the pump flow rate
has dropped,
then the exhaust filter is clogged and must be replaced.
Note
: Exhaust filters cannot be cleaned successfully. Clogged exhaust
filters must be replaced with new ones.
If
the drive motor draws less current than usual,
then the exhaust filter is broken through and must be replaced.
If the discharged gas contains oil,
the exhaust filter can either be clogged or broken through and, if appli-
cable, must be replaced.
Change of the Exhaust Filter
DANGER
_age32
In case the vacuum pump conveyed gas that was contaminated
with harmful foreign material the exhaust filter will be contami-
nated with harmful material.
Danger to health during the changing of the contaminated exhaust
filter.
Danger to the environment.
Wear personal protective equipment during the changing of the
contaminated exhaust filter.
Used exhaust filters are special waste and must be disposed of
separately in compliance with applicable regulations.
Removing the Exhaust Filter
Make sure that the vacuum pump is shut down and locked against
inadvertent start up
Prior to disconnecting pipes/lines make sure that the connected
pipes/lines are vented to atmospheric pressure
Make sure that the oil is drained
Remove the discharge line, if necessary
Remove the oil separator (f)
Undo the exhaust filter from the oil separator (f)
Inserting the Exhaust Filter
CAUTION
_a
The non-OEM spares market offers exhaust filters that are geomet-
rically compatible with Busch-vacuum pumps, but do not feature
the high retention capacity of genuine Busch-exhaust filters and de-
teriorate the service life and the efficiency of the vacuum pump due
to their increased back pressure.
Increased risk of damage to health.
Adverse effect on efficiency and service life.
In order to keep the emission on the lowest possible level and to
preserve efficiency and service life only genuine Busch-exhaust fil-
ters shall be used.
