Mechanical installation
2.1.1
Basics
There are multiple potential sources of oil mist inside an engine. These are for
example defective main bearings, connecting rod bearings as well as piston
seizures, chains and covers of pumps. For each of these individual sources you
could determine the "optimum" suction point. The result would be a vast number of
holes to be distributed over the entire engine. To find out a safe and economic
solution to monitor oil mist SCHALLER AUTOMATION recommends the OMDEA-test
(Oil Mist Detection Efficiency Approval). In each case the following rules are
recommended.
CAUTION! Do not ignore the warnings. The safety of persons
can be endangered
Following rules are recommended by SCHALLER AUTOMATION:
Use at least one suction point per compartment.
Use always the long version of the suction funnels. This makes the
installation independent from the rotation sense of the engine.
At least one suction point per chain drive or gear drive is necessary.
Avoid the splash oil disk of the crankshaft bearings.
Select points in the upper area of the crankcase, as oil mist tends to rise
upwards!
The detection unit has to be placed above the suction points.
Installation Rules: it is not allowed to make U-bends or kinks in the tubing
system.
o
VN115 with pipe siphons: Mount one pipe siphon at each end of the
horizontal header pipes, place the pipes a little bit above the suction
points and connect the pipes and the engine wall connections with
flexible tubes.
o
VN115 with siphon blocks: Use one siphon block at each compartment.
If possible mount the device on the engine side opposite to the crankcase
relief valves, to reduce danger to the crew during a damage situation.
If possible place the VISATRON® detection unit in the center of the engine to
avoid long pipe runs.
Select only suction points which allow the use of long suction funnels. In this
case the installation side is independent from the rotation sense of the
engine. Installations without any suction funnels are not allowed.
