Compressor blocks IK150,IK180 IK15.1, IK15.11 and
IK18.1
The compressor blocks IK150, IK15.1, and IK180 are
used to compress air in the high pressure ranges PN200 and
PN300 for breathing air application, for industrial applica
tion up to 350 bar (5,000 psi). The max. allowable operating
pressure (adjustment of final pressure safety valve) is 225
bar (3,200 psi) or 330 bar (4,700 psi), respectively for
breathing air units, and 365 bar (5,290 psi) for industrial
units.
Compressor blocks IK15.11 and IK18.1 are used to com
press air in the high pressure range PN420 for breathing air
application, for industrial application up to 500 bar (7,000
psi). The max. allowable operating pressure (adjustment of
final pressure safety valve) is 435 bar (6,300 psi) for breath
ing air units, and 525 bar (7,600 psi) for industrial units.
All compressor blocks except the IK18.1 are of a four stage,
four cylinder design. The four cylinders are arranged at an
angle of 90to each other, 1st and 2nd stage, and 3rd and
4th stage opposite to each other. The 4th stage cylinder is
lubricated by means of the force-feed lubrication system,
the other cylinders are splash-lubricated.
The design of the compressor block is shown in Fig. 8.to
Fig. 11. For the mode of operation refer to the flow diagram
in sec. F.
