In a steam turbine and reduction gear main propulsion plant, the alarm sensor for low turbine oil pressure is usually installed __________.

🔍 Key Concepts

• Purpose of low lube oil pressure alarms in turbine and reduction gear systems • How oil is distributed through supply headers, bearings, and returns in a main propulsion plant • Where a pressure reading best represents the actual pressure available at the bearings

💭 Think About

• Think about what the alarm is trying to protect: which components are most critical if oil pressure drops? • Would you want the alarm to sense pressure before or after the oil has passed the bearings? Why? • If there are several bearings supplied from a common header, where would a single sensor give the most representative reading of the lowest pressure in the system?

✅ Before You Answer

• Identify the direction of oil flow: pump → cooler/filter → header → bearings → drain/return • Decide whether the alarm should see pressure as close as possible to the bearings or after the oil has already done its job • Consider which location would detect a pressure loss affecting all bearings rather than just one point in the system

Question 1 of 27070

In a steam turbine and reduction gear main propulsion plant, the alarm sensor for low turbine oil pressure is usually installed __________.

at a point on the inlet side of the main bearings as close to the bearings as possible

at the end of the supply line header to the bearings

at the outlet of the main thrust bearing

at a point on the outlet side of the main bearings as close to the bearings as possible
