Technical data HV2/219
General description:
Model HV2/219 LP is a two cylinder, two stage, water cooled compressor. The compressor is mounted together with an electric motor on a well stiffened foundation with a flexible coupling between the flywheel and drive flange.
All bearings are pressure lubricated by an oil pump gear driven by the crankshaft.
Two replaceable coolers are fitted in the compressor cylinder block. The first serves to cool the air after first stage compression,the second provides cooling after second stage compression.
The cooling water intake and outlet are located so that the water circulates through the cylinder block and ensures efficient cooling of the air and cylinder walls. Design particulars:
