ICHEM QUIZ 6

Which of the statements is correct? In the fuel oil service system:

• The volume of fuel oil that flows through the circulating pump pressure control valve is inversely proportional to the volume that flows through the the supply pump pressure control valve.

• The volume of fuel oil that flows through the flowmeter is the same volume that is not flowing through the pressure control valves.

• The volume of fuel oil that flows through the flowmeter is not the same volume that is not flowing through the pressure control valves.

• The volume of fuel oil that flows through the circulating pump pressure control valve is directly proportional to the volume that flows through the the supply pump pressure control valve.

In the fuel oil service system, when the engine increases speed:

• The flow through both pressure control valves increases.

• the flow through the pressure control valves reduces.

• The flow through both pressure control valves does not reduce.

• the flow through the pressure control valves does not increase.

In the Ship in, what is the in the air control system of auxiliary engine at the top?

• Control stop solenoid valve.

• fuel oil starting limiter solenoid valve

• [none]

• fuel oil stopping limiter solenoid valve

What happens to the fuel oil flow when the main engine is at full speed?

• The fuel oil flow through to both pressure control valves is at the lowest.

• The fuel oil flow through to both pressure control valves is at the highest.

• [none]

• The fuel oil through one of the pressure control valves is at their lowest while the other is at their highest

Which is not part of the safety system in the fuel oil transfer system?

• Start and stop switches.

• Quick Closing Valve

• Vent Head

• Float Switches

In the fuel oil purifying system, in following the fuel oil flow, what component is after the fuel oil heater?

• Purifier

• Thermostat

• 3-way valve

• Thermostatic Valve

Which of the statements is NOT correct?

• The volume of fuel that passes through the flowmeter is NOT equal to the volume that is not recirculated.

• The volume of fuel that passes through the flowmeter is NOT equal to the volume that is recirculated.

• The volume of fuel oil that passes through the flowmeter is equal to the volume that is not recirculated in the supply circuit

• The volume of fuel oil that passes through the flowmeter is equal to the volume that is recirculated in the supply circuit

What happens to the fuel oil flow when the main engine is stopped?

• The fuel oil flow through to both pressure control valves is at the lowest.

• The fuel oil flow through to both pressure control valves is at the highest.

• [none]

• The fuel oil flow through one of the pressure control valves is at the lowest, while the other is at the highest

In the fuel oil transfer system, how many float switches are there is the settling tank:

• 3

• 4

• 5

• 6

What is the component before the fuel oil purifier?

• Fuel oil heater

• 3-way valve

• Thermostat

• Shut off valve
