Pre-lubrication oil system
Why pre-lubrication?
Pre-lubrication is necessary in situations listed below, in order to provide
sufficient lubricating oil at locations where this is most needed (oil pump,
bearings, pistons en piston rings) to ensure that any risk on 'dry running' is
minimized or even better eliminated. Dry-running of oil pump bearings pistons
and piston rings will initiate and after initiation worsen the wear of the parts
mentioned and eventually even damage the crank shaft and cylinder liners or
even more parts.
When pre-lubrication?
1.
Before initial start-up
2.
Before start-up after overhauling compressor
3.
Before start-up after renewal of oil
4.
Before start-up after standstill period of more than 1 month
