4.3.2 V-belt drive
V-belt drive is recommended where the motor speed
needs to be transformed or reduced.
Note nominal speed according to „1.0
Technical data“ on page 3!
The V-belt pulleys listed in the following diagrams can
be placed directly on the free end of the shaft.
DIAGRAM 5. V-belt pulley for SLS 34
DIAGRAM 6. V-belt pulley for SLS 54
Carefully and precisely align the axes in all planes,
both for the driving as well as for the driven shaft!
The grooves of the belt pulley must not be offset.
The selected length of the V-belt is decisive for uni-
form belt tension.
The tension setting for the V-belts must allow them to
be depressed by about an inch.
4.3.3 Coupling drive
see „Stationary operation“ on page 8.
4.4 Pipelines
Remove the dummy flanges and plugs from all pipe-
lines, in addition thoroughly clean all pipes prior to fit-
ting.
Condensate traps with drain cocks must be fitted at
the lowest point of the outlet pipes, in particular in
riser pipes.
4.5 Safety and monitoring equipment
4.5.1 Check valve
For compressor and vacuum pumps, the check valve
(8) is to be fitted in way of the intake fitting (7)
(Diagram 7 on page 12).
On machines with a four-way cock, the
check valve is fitted inside the cock!
4.5.2 Safety valve
In accordance with the applicable regulations, a non-
lockable safety valve must be fitted downstream of
every compressor.
The size and setting of the safety valve must be
selected so that the highest permissible pressure is
not exceeded by more than 10 %.
It must be able to blow-off the complete quantity sup-
plied by the compressor.
The safety valve must be fitted with a manually opera-
ted vent.
Important installation instructions:
•
Install directly downstream of the com-
pressor and upstream of every shut-off
fitting.
•
The component markings by the TUV and the
security seals must be present.
•
Adjust in accordance with the permissible opera-
ting pressure (see „Technical data“ on page 3.).
