Compressor block IK120
The design of the compressor block is shown in Fig. 5. For the
mode of operation refer to the flow diagram, Fig. 6.
The compressor block is used to compress air in the high
pressuare range. The max. allowable operating pressure is
350 bar.
The compressor block is of a three stage, three cylinder
design. The cylinders are arranged in a W form, 1st stage in
the centre, 2nd stage on the right, and 3rd stage on the left
side looking from the filter side.
These compressor blocks are particularly suitable for
continuous operation because of their rugged design and
the corrosion resistant intermediate filter and cooler
assemblies. Smooth running is a particular feature of this
BAUER design. The balance of masses of the 1st rank is zero.
The moving parts of the driving gear are all equally balanced.
This results in a vibration-free running.
The driving gear is fitted with energy saving cylinder roller
bearings. The upper and lower connecting rod bearings are
also roller bearings. This allows for an even longer life which
lasts at least 30,000 operating hours.
