5.1
Lubricating oils for VM screw compressors
Continuous operation with differential pressure < 2 bar
Lubricant to be used :
ISO VG 46
Fully synthetic (PAO) poly-alpha-olefin,
gearbox or compressor oil
Example
:
BP Enersyn RC-S46
Order no.: 174 884
Operating conditions:
On VM machines with an installed pressure ratio of �i = 3 and a
differential pressure of ∆p = (p2-p1) < 2 bar in continuous operation.
Compressors with �i = 4 are
NOT permitted for differential pressures of < 2 bar
during continuous operation.
5.2
Lubricating oils for VML screw compressors
Continuous operation with differential pressure < 1 bar
Lubricant to be used :
ISO VG 46
Fully synthetic (PAO) poly-alpha-olefin,
gearbox or compressor oil
Example
:
BP Enersyn RC-S 46
Order no.: 174 884
Operating conditions:
On VML machines with an installed pressure ratio of �i = 1.8 and a differential
pressure of ∆p = (p2-p1) < 1 bar in continuous operation.
Compressors with �i = 2.3 are
NOT permitted for differential pressures of < 1 bar
in continuous operation.
Changing to other oil types
The Aerzener special rotary piston oil and PAO oils are completely consolute.
•
When switching from one type of oil to another, there are no special measures
to be taken into account. However, in order to maintain the useful properties of
the new oil type, the oil to be changed should be completely drained and a single
intermediate oil change undertaken after an operating period of 100 hours. Only
the same oil should be used for refilling.
