5.2.16 Pure oil mist Lubrication

Pure oil mist system utilize a continuous oil mist flow

through the bewaring housing to deliver clean oil

directly to the bearings and to maintain an outward

flow of air from the housing to prevent the ingress of

moisture and other corrosive contaminants. . If the

pump will be started after a longer storage period, the

bearing housing should be first flushed and cleaned

with gasoline. It is not necessary to remove the

preservation oil.

The supplied air must be dry and clean.

The cleanness shall be < 5µm.

The bearing housing requires a minimum SCFM

value as follows:

The pressure in the bearing housing shall be 0,05

bar (0,74 psi) (20 inches of water column). A

continuous lubrication should occur during

operation and standby.

Pre Lubrication shall be performed at least 1h

before first start up.

After start up the bearing temperature

must be observed carefully. The temperature at the

bearing housing should not exceed 85°C.

Refer to the General Arrangement

drawing regarding the connections for the oil mist

lubrication.

5.2.17 Oil quality
