BUSCH R5 RE 0016 B, Инструкция по установке и эксплуатации

Страница: 3 / 24

Product Description
Use
The vacuum pump is intended for
–
the suction
of
–
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in-
creased thermal and/or mechanical load on the vacuum pump and is
permissible only after prior consultation with Busch.
Max. allowed temperature of the inlet gas: 40 °C
Disclaimer: The vacuum pump comes with a couple of features
(
Ú
page 3: Safety Concept) meant to accommodate the approval of
the vacuum pump for use in/with potentially explosive atmosphere.
The provision of these features by Busch does not constitute any kind
of implicit approval or certification of the vacuum pump for the use
in/with potentially explosive atmosphere. The assessment of the suit-
ability of these features for the safe operation of the vacuum pump
in/with potentially explosive atmosphere is solely in the responsibil-
ity of the manufacturer of the superordinate machinery (i.e. the ma-
chinery into which the vacuum pump is to be incorporated) and/or
the certifying body for the superordinate machinery. Further measures
may have to be taken, depending on the specific application and/or
the applicable national explosion safety regulations.
The explosion safety regulations of the European Union require a dif-
ferent approach, hence the vacuum pump R 5 RE 0016 B / RE 0040 B
/ RE 0063 B is not meant for use in/with potentially explosive atmo-
sphere within the European Union.
In case the vacuum pump is equipped with a gas ballast (optional) wa-
ter vapour within the gas flow can be tolerated within certain limits
(
Ú
page 9: Conveying Condensable Vapours). The conveyance of
other vapours shall be agreed upon with Busch.
The vacuum pump is thermally suitable for continuous operation
(100 percent duty).
The vacuum pump is ultimate pressure proof.
Safety Concept
The vacuum pump comes with a couple of features meant to accom-
modate the approval of the vacuum pump for use in/with potentially
explosive atmosphere. These measures reflect two safety principles be-
ing independent from each other:
1. Avoidance of ignition caused by an electric or non-electric ignition
source inside or outside the vacuum pump.
In order to avoid an ignition inside as well as outside the vacuum pump
must be kept from running out of oil and must also be kept from gen-
erating too high pressure inside the oil separator (j) (too high pressure
entails too high temperature!).
–
The sight glass (p) must be read every day prior to the start of the
vacuum pump, in case of continuous operation again in intervals of
max. 24 hours. If a daily inspection cannot be guaranteed, an oil
level switch must be installed that will shut down the vacuum
pump in case of low oil level (the oil level switch does not form
part of the Busch scope of delivery).
–
The safety valve relieves overpressure that might occur e.g. due to
a partially clogged exhaust filter, a partially clogged flame arrestor
