HYDRAULIC ROTARY VANE COMPRESSORS
OPERATING INSTRUCTIONS
Picture 7: Operating description: Oil cooling
7. The heat generated by the compression of the air is transferred to the oil. Oil is
cooled by passing it through a special radiator which is cooled by an air flow
of a fan. Thermostatic by-pass valve controls the oil temperature during the
operation.
When supply line is closed and preset air pressure is reached, compressor starts
to run automatically in off-load mode. Pneumatically controlled intake valve is
closed and compressor’s internal pressure drops to 3 bar. Pressure in supply line
remains until supply line is opened.
When the compressed air is consumed, off-load automatic controls the intake
valve according to the current air demand.
The nominal discharge is achieved when the compressor is rotated by hydraulic
flow adequate to the nominal rotation speed.
