Conveying Condensable Vapours
Version “Aqua”:
♦ Close the shut-off valve in the suction line
♦ Warm up the vacuum pump for approx. 10 minutes
At process start:
♦
Open the shut-off valve in the suction line
At the process end:
♦ Close the shut-off valve in the suction line
♦ Open the ambient air valve
♦ Operate the vacuum pump for another approx. 10 minutes
♦ Close the ambient air valve
♦ Regularly drain condensate from the anti-pulsation
chamber (n)
Maintenance
•
Prior to disconnecting connections make sure that the
connected pipes/lines are vented to atmospheric pressure
Maintenance Schedule
Note: The maintenance intervals depend very much on the
individual operating conditions. The intervals given below are upper
limits that must not be exceeded.
Particularly heavy duty operation, such like high dust loads in the
environment or in the process gas, other contaminations or ingress
of process material, can make it necessary to shorten the
maintenance intervals significantly.
Monthly
In case of dusty process gases:
Note: In case of dusty process gases despite an inlet air filter
finest dust particles can enter the vacuum pump and collect in
the anti-pulsation chamber. By means of short-time operation
with unrestricted suction (= maximum flow rate) the dust will be
blow out from the anti-pulsation chamber.
♦
Open the suction connection
♦ Operate the vacuum pump for approx. 5 minutes with
unrestricted suction
•
Make sure that the vacuum pump is shut down and locked
against inadvertent start up
In case an inlet air filter (l) is installed:
♦ Check the inlet air filter (l), if necessary replace
In case of operation in a dusty environment:
♦ Clean as described under
➔
page 13: Every 6 Months
Every 3 Months:
•
Make sure that the vacuum pump is shut down and locked
against inadvertent start up
•
Check the level of the synchronising gear oil
The level shall be slightly above the middle of the sight glass (f).
The level of the synchronising gear should stay constant over the
lifetime of the oil. If the level does fall, the gear is leaky and the
vacuum pump requires repair (Busch service).
WARNING
Do not open the vacuum pump in potentially explosive
atmosphere.
Risk of explosion!
CAUTION
Due to the corrosion protection coating CPC the vacuum pump
is capable of conveying water vapour.
Very humid process gases and/or adverse operating cycles can
lead to residual condensates, though, which cause corrosion.
If this is the case, it is necessary to counteract residual
condensates by warming up the vacuum pump, conveyance of
ambient air after process end and regular draining of the anti-
pulsation chamber (m).
WARNING
The approval of the vacuum pump for use in potentially
explosive areas remains valid only if the maintenance is
conducted regularly according to the maintenance
schedule below and genuine spare parts and consumables,
approved for use in potentially explosive areas by Busch,
are used exclusively.
Maintenance work must be executed by qualified
personnel, specially instructed in the maintenance of this
type of vacuum pump by Busch.
CAUTION
During operation the surface of the vacuum pump may reach
temperatures of more than 70 °C.
Risk of burns!
DANGER
In case the vacuum pump conveyed gas that was
contaminated with foreign materials which are dangerous
to health, harmful material can reside in filters.
Danger to health during inspection, cleaning or
replacement of filters.
Danger to the environment.
Personal protective equipment must be worn during the
handling of contaminated filters.
Contaminated filters are special waste and must be
disposed of separately in compliance with applicable
regulations.
