6 Commissioning
6.1 Preparation for commissioning
The components of the screw compressor air end
system are carefully checked and tested at the
factory. These tests ensure that the required per-
formance and checking data are complied with.
Nevertheless, the screw compressor air end sys-
tem should be observed during the initial operating
hours.
Before commissioning, it must be checked
whether the screw compressor air end system has
been properly installed.
As it is probable that there is no oil in the feed
chamber following transport and storage, 0.53 to
2.1 quarts (0.5 to 2 liters) of clean oil of the speci-
fied oil quality must be added to the system before
initial start-up in dependence on the screw com-
pressor air end size and the system. This prevents
the rotors from running dry during starting.
Caution:
With regard to commissioning, the applicable reg-
ulations of the specific country must be observed.
In Germany these include the Operating Safety
Ordinance.
The following points must be observed prior to ini-
tial commissioning:
– Be sure to observe the direction of rotation (see
chapter 6.2 "Checking direction of rotation").
– The final pressure specified on the nameplate
may not be exceeded.
– Do not switch off screw compressor air end
systems running under load at the Emergency-
Stop or main switch.
– Check the oil level.
– Before each initial commissioning and when
recommissioning after a longer shut-down of
the screw compressor air end system, always
carry out the activities described in chapter 6.4
"Recommissioning screw compressor air end
system".
– With a belt drive: check the belt tension and belt
routing (see chapter 7 "Maintenance").
– Check the position of the shut-off valve.
– Check all screw fitting and fastening screws for
firm seating.
Caution:
– Commissioning is only allowed when the sys-
tem is complete (Danger from being pulled into
the screw, hot oil and compressed air escap-
ing).
6.2 Checking direction of rotation
Direction of rotation:
Standard model rotating to the left (counter-
clockwise) looking at the shaft.
The design with a transmission rotates to the
right (clockwise)
Caution:
The direction of rotation of the screw compressor
air end must be checked during initial commission-
ing and each time changes are made to the elec-
trical supply line of the electric motor drive. For this
purpose, switch on the drive motor briefly and then
switch off again immediately.
An incorrect direction of rotation for more than
2 seconds will result in destruction in the screw
compressor air end. Reconnect the phases of the
connection cable if necessary.
6.3 Test run
Caution:
The system is discharged extremely quickly down
to the opening pressure "minimum pressure valve"
in the Stop mode, "with shut-off valve opened"!
This can result in the oil in the separating tank
foaming up.
The possible consequences include:
– Oil escaping with the discharge air
– Oil flooding the fine separator cartridges
– Compressed air containing oil when
restarting the system
Therefore, the following points must be observed
during the test run:
– Only switch off the system with the shut-off
valve closed!
– If possible, connect the system to a com-
pressed-air reservoir!
Caution:
Maintain appropriate safety distance.
There is a risk of injury if the rotors are blocked.
For safety reasons, only drive for a few seconds
during initial startup.
For safety reasons, operation in open state must
not be carried out.
Wear ear protection.
