Ingersoll-Rand SSR M11, Operation And Maintenance Manual

GENERAL INFORMATION

M4 M5,5 M7,5 M11
The power transmission from the drive motor to the airend male
rotor is by pulley and V–belts. The constant auto tensioning system,
using motor mass and torque, ensures that the belts are always under
the correct tension, eliminating the need for adjustment and maximising
the life of the belts.
By cooling the discharge air, much of the water vapour naturally
contained in the air is condensed and may be drained from the
downstream piping and equipment.
The coolant system consists of a sump, cooler, thermostatic valve
and a filter. When the unit is operating, the coolant is pressurised and
forced to the compressor bearings.
The compressor load control system is automatic ’On–Off line’. The
compressor will operate to maintain a set discharge line pressure and
is provided with an autorestart system for use in plants where the air
demand varies widely.
Safety of operation is provided for as the compressor will shut down
if excessive temperatures or electrical overload conditions should
occur.
