4 GENERAL DESCRIPTION AND OPERATION
4.1 CONFIGURATION
The 5217.2.IA water-cooled compressor is of the four cylinder, single acting, two stage, 90°-vee
configuration which provides complete primary balance.
4.2 LUBRICATION
The forced feed system is shown on following page.
The specified lubricant must be used at all times to ensure safe and efficient operation with minimum
wear and maximum protection against moist air corrosion.
Recommendations are the result of extensive research at Reavell and all responsibility for the use of an
oil other than that recommended is placed on the purchaser and his oil company.
THE NORMAL GUARANTEE MAY BE INVALIDATED SHOULD A FAILURE BE ATTRIBUTED BY
REAVELL TO THE USE OF A LUBRICANT NOT RECOMMENDED.
4.3 SYNTHETIC OILS
These oils are arrived at by chemical synthesis from petroleum feed stocks, although in some
cases they can be from vegetable and mineral oils rather than by straight run distillation of crude.
Advantages
Carbon deposits are reduced compared with mineral type oils.
It may be possible to extend oil change periods in some cases.
Wear rates are reduced.
These oils, being produced to close tolerances, have properties and performance which are consistent
from batch to batch.
Oil carry-over can be reduced by up to 35%.
Disadvantages
Certain materials, e.g. some rubbers, paints, plastics and metals are not compatible with synthetic oils.
All components on the booster are compatible but as problems may exist with auxiliary equipment, their
manufacturers should be consulted.
The following synthetic type oils are approved:-
*REAVELLITE ANDEROL 555
MOBIL RARUS 827 CASTROL SN100
* Preferred oil
4.4 COOLING
Cooling is by water flowing through the jackets and passages, either from the mains or a closed circuit
system using a radiator or cooling tower. A bursting disc is fitted to prevent excessive pressure build up
in the water spaces if a leak should occur from the coolers.
Electrolytic corrosion of the cooler tubes and fittings is prevented by the provision of a sacrificial anode
(corrosion rod) in the water jacket which will be chemically attacked before the machine components.
4.5 DRIVE
Drive is by either flange mounted motor or vee belt transmission from a suitable power source, such as
electric motor or diesel engine.
