Ship Specific Flashcards
Compressor
Compresses and pumps low pressure refrigerant vapor into the condenser at high pressure
Evaporator/Cooling Coil
Liquid refrigerant is turned into vapor state and absorbs heat from the air and chill water
Condenser/ heat exchanger
Vapor refrigerant is turned into a liquid by a cooling medium
Receiver
Hold liquid refrigerant until it is needed
Thermal Expansion Valve
Valve that regulates the flow of refrigerant going to the evaporator/cooling core
Chilled Water Pump
1 & 2 chill water pumps located in AMR
Production of Potable Water
Strainer, low pressure pump, 5 micron filter, 20 micron filter, high pressure pump, membranes, in-line brominator, and potable water tank
Potable Water Requirements
.2 - 2.0 approved government source 2 or greater from non government source
Steering System
Trick wheel in aft steeringHand pump in aft steering Hand wheel in the bridge
Bow Thruster
Aids in steering, powered by turbine
LLPM
Light Load Propulsion Motor used for minesweeping
GATX
General American Tank Corporation
GATX modes
At sea - outside 3 NMIn port - held in CHT tank and pumped to shore stationTransit - within 3 NM, held in collection tank
Gray Water
Dirty water from sinks, drainage, scuttles
Black Water
Piss and shit
Macerators
Grinds CHT to prevent clogging the transfer pump or piping2 GATX, 1 Doc’s P-way
What is a brominator?
Used to chemically treat ship’s water to the required bromine level
Potable Water Capacity
6000 gallons per day
Low Pressure Air (LP)
0-125 psiUsed to start MMGTG, MPDEs, SSDGs, engage clutches for MPDEs and LLPMs, to engage shaft brakes, and supply air through out the ship
Medium Pressure (MP)
125-600 psiControl UCHS
Reverse Osmosis
Located in AMR3x2k R/O
Power Turbine
Rotates at a constant rate of 22300 rpmFirst stage reduction reduces to 6000 rpmSecond stage reduces to 1800 rpm
Solar Gas Turbine Controls
CCS at the ECCO console and locally by the AMRO at the local control panel
Purpose of Solar Gas Turbine System
Provides direct current voltage to DC switchboardDC switchboard provides power to bow thruster, mag-tail, and LLPM
