XK12 Installation, Operating & Maintenance Manual
Installation
3.5 PTO and prop. shaft drive alignment
(cont.)
Alignment - See Figure 8
The axis on majority of PTO’s is mounted at approximately 2° - 5° to the
horizontal, which refl ects the angle of the engine and gearbox.
The compressor should be mounted so that its drive axis is parallel to the
PTO’s drive axis.
The compressor should also be mounted so that the prop. shaft angle
between the PTO and XK12 in any plane is less than or equal to 12°.
Consideration should be given to the prop. shaft length when mounting the
machine.
The prop. shaft should be sized so that it always has sliding clearance.
It is recommended that a torque limiting device should be installed between
the compressor and PTO drive fl anges to protect the drive line against all
eventualities. Torque limiting couplings are supplied as standard.
3.6 Pipe Work
Figures 10a and 10b show a breakdown of packages 1 and 2.
Flexible pipe is provided in the inlet induction kit with both packages.
Where any pipe work is to be fabricated using slip-on-weld fl anges, such
as on the inlet in Fig 9, the following points should be followed to prevent
damage to the machine and contamination of the discharged product.
• All inlet pipe work must be stainless steel or thick wall aluminium to
help prevent corroded particles entering the machine and reduce
noise emissions.
• Outlet pipe work can fabricated from any material (including mild
steel) to suit the application.
• All fabricated pipe work, should be de-scaled/cleaned before
commissioning the compressor.
• Pipe work should be attached to the vehicle chassis using fl exible
mountings to prevent unnecessary vibration and noise transfer.
• A fl exible element is recommended in the discharge pipe work (and
inlet pipe work when necessary) to prevent distortion of the XK12
from the fabricated pipe work through chassis movement and heat
expansion.
3.7 Commissioning Filter
The compressor is supplied with a commissioning fi lter fi tted to the inlet
port to prevent debris entering the machine during the installation and initial
commissioning processes.
Also check the prop shaft
manufacturers information.
NOTE
After the initial 15 minute
commissioning run (at
1000rpm, 1810 rpm high
speed), the fi lter
must
be
replaced with the standard
inlet fl ange gasket.
Prolonged or higher speed
operation with the fi lter fi tted
will result in machine failure.
Tighten item 1 fi g. 9 to a
torque of 50 Nm. See above.
NOTE
Figure 9. Inlet Flange
The compound prop.shaft
angle must also be less than
12°.
