The inlet end lube oil temperature corresponds to the
oil temperature in the tank and is displayed locally by
thermometer MBV23CT511. Temperature at the outlet end
is displayed locally by thermometer MBV23CT512.

Cooling water pressures are displayed locally; at the
inlet end by pressure gauge MBV23CP513 and at the
outlet end by pressure gauge MBV23CP514. Isolation of
these pressure gauges, i.e., for test purposes, is possible
using shutoff valves MBV23AA311 and MBV23AA313.
Function
The lube oil cooler is connected in the supply line of the
lube oil system and cools the lube oil to such an extent that
a downstream temperature control valve can produce a
mixture with the oil cooler bypass flow so as to establish
the lube oil supply temperature required by the bearings.
Cooling water temperatures are displayed locally; at the
inlet end by thermometer MBV23CP513 and at the outlet
end by thermometer MBV23CP514.
Spring-loaded safety valve MBV23AA191 is installed on
the water side to protect the cooler against excessive
internal pressure.

Non-redundant
water-cooled,
plate-type
heat
exchanger (PHX) MBV23AH001 is implemented to cool the
lube oil. Heat removal is achieved using a cooling water
loop.
Configuration
This cooler is installed in the immediate vicinity of the
lube oil tank.
Configuration and Functional Principle
Warm lube oil flows into cooler MBV23AH001 at
connection HA and after cooling exits the cooler at
connection HB, flowing in the direction of the lube oil
system temperature control valve.
Shutoff valve MBV23AA401 is used to drain the oil side
of the PHX. Permanent venting at the highest point of the
cooler is performed via orifice MBV23BP511. A venting line
runs from connection HC to the lube oil tank.
The lube oil inlet end pressure corresponds to the
system pressure upstream of the lube oil system cooler
and is displayed locally on pressure gauge MBV23CP511.
The lube oil pressure at the outlet end is displayed locally
on pressure gauge MBV23CP512. Isolation of these
pressure gauges, i.e., for test purposes, is possible using
shutoff valves MBV23AA301 and MBV23AA303.
