Schmalz EVE-KL, Operating Instructions Manual

Page: 8 / 20

Delta connection, multi-voltage motor with 12 terminals (middle
voltage):
Star connection, multi-voltage motor with 12 terminals (high voltage):
Version with three-phase motor:
♦
Determine the intended direction of rotation with the
arrow (c) (stuck on or cast)
♦
“Bump” the drive motor
♦
Watch the fan wheel of the drive motor and determine the
direction of rotation just before the fan wheel stops
If the rotation must be changed:
♦
Switch any two of the drive motor wires (three-phase
motor)
Connecting Lines/Pipes
•
Connect the suction line
•
Connect the discharge line
Installation without discharge line:
♦
Make sure that the gas discharge (k) is open
•
Make sure that all provided covers, guards, hoods etc. are
mounted
•
Make sure that the cooling air inlets and outlets are not covered
or obstructed and that the cooling air flow is not affected
adversely in any other way
Recording of Operational Parameters
As soon as the vacuum pump is operated under normal operating
conditions:
•
Measure the drive motor current and record it as reference for
future maintenance and troubleshooting work
Operating Notes
Use
The vacuum pump is intended for
−
the suction
of
−
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Max. allowed temperature of the inlet gas: 40 °C
Standard-version:
The gas shall be free from vapours that would condensate under
the temperature and pressure conditions inside the vacuum
pump.
Version “Aqua”:
The vacuum pump is intended for the placement in a non-potentially
explosive environment.
Max. permissible number of startings per hour: 12
Vacuum pumps MM 1324 AV standard-version are thermally
suitable for continuous operation down to ultimate pressure.
Vacuum pumps MM 1324 AV Version “Aqua” are thermally suitable
for continuous operation at intake pressures down to 200 hPa abs
(200 mbar abs). By means of process control and/or vacuum relief
valves it must be made sure that the minimum allowed intake
pressure will not be underrun.
Vacuum pumps MM 1202 AV, MM 1200 AV, MM 1252 AV and
MM 1250 AV are thermally suitable for continuous operation at
intake pressures down to 100 hPa abs (100 mbar abs). By means of
process control and/or vacuum relief valves it must be made sure
that the minimum allowed intake pressure will not be underrun.
Vacuum pumps MM 1322 AV and MM 1320 AV (version
600…3600 min
-1
) are thermally suitable for continuous operation at
intake pressures down to 150 hPa abs (150 mbar abs). MM 1320 AV
(version 600…4200 min
-1
) are thermally suitable for continuous
operation at intake pressures down to 200 hPa abs (200 mbar abs).
By means of process control and/or vacuum relief valves it must be
made sure that the minimum allowed intake pressure will not be
underrun.
Version “Aqua”:
The safety valve on the vacuum pump protects the vacuum
pump against overheating only. It is not designed for frequent
use and must therefore not be used as a system pressure
regulating valve.
CAUTION
The vacuum pump is designed for operation under the
conditions described below.
In case of disregard risk of damage or destruction of the
vacuum pump and adjoining plant components!
Risk of injury!
The vacuum pump must only be operated under the conditions
described below.
CAUTION
Operation in the wrong direction of rotation can destroy the
vacuum pump in short time
Prior to starting-up it must be made sure that the vacuum pump
is operated in the proper direction (clockwise rotating field).
Installation and Commissioning
Seite
8 30.30.01.00867-00_EN / 04.2015
Conveying media with a lower or higher density than air leads to an
increased thermal and/or mechanical load on the vacuum pump and
is permissible only after prior consultation with
Schmalz
.
The vacuum pump features the corrosion protection coating
CPC and is capable of conveying water vapour
➔
page 9:
Conveying Condensable Vapours). Conveyance of other
vapours shall be agreed upon with
Schmalz
. Conveyance of
water or other liquids in liquid phase increases the power
consumption and shall therefore be avoided (risk of drive
overload).
