5.1 Assembly
5.1.1 Fastening screws
Figure 5-1
Threaded holes 1 are provided on the sides of the
compressor air ends. These are used for standard
fastening. Only suitable screws with a METRIC
THREAD are to be screwed into this female
thread.
In addition, there three-point fastening is also pos-
sible.
5.1.2 Three-point fastening
Figure 5-2
With screw compressor air ends driven by a V-
belt, it must be ensured that the screw compres-
sors are not twisted on the delivery side under
mounted supports. In case of twisting or deforma-
tions of the compressor air end, there is a danger
of the rotors jamming and the screw compressor
air end being destroyed.
The contact surfaces should be machined and flat.
Only three of the holes 1 present in the housing/
support feed may be used for fastening. The fourth
hole 2 is to remain clear (three-point fastening).
5.1.3 Pipe connections
Pipe connections with a female thread for a com-
pressed-air outlet, oil circulation, draining and con-
trol lines are provided on the compressor air ends.
Only fittings or screw connections with a CYLIN-
DRICAL INCH THREAD suitable for these female
threads may be screwed in.
CONICAL THREADS must be avoided, as dam-
age to the housing of the screw compressor air
end can occur when screwing in (see installation
drawing).
Caution:
The maximum permissible tightening torque for all
screw connections may not be exceeded.
VDI 2330 (see chapter 9.2 "Tightening torques")
Only screws suitable for fastening the compressor
air ends may be used for this purpose.
Consult ROTORCOMP beforehand if necessary.
