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
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
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 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
