Prelim Quiz 3

What is the primary reason for conducting a general inspection before starting a separator system?

• To verify the separator's electrical consumption

• To ensure cleanliness, check for leaks, and confirm proper component installation

• To determine the speed of the separator motor

• To check if the sludge discharge valve is fully open

Why is it essential to inspect the bowl and bowl hood before starting the separator?

• To confirm the separator is receiving adequate power

• To verify if the sludge pump is functioning properly

• To detect cracks, misalignment, or contamination that may affect efficiency

• To ensure the separator achieves maximum rotational speed

How does the gravity disk influence the separation process?

• It regulates the oil temperature to improve separation efficiency

• It controls the interface between oil and water inside the separator

• It ensures that the separator bowl is correctly aligned with the shaft

• It adjusts the pressure within the separator chamber

What should be checked when inspecting the centrifugal pump before startup?

• Presence of air bubbles in the oil feed line

• Proper lubrication, absence of leaks, and smooth operation

• Whether the oil viscosity matches the design specification

• If the sludge discharge rate matches the system capacity

Why is checking the control panel important before starting the separator?

• To confirm that pressure and temperature readings are within safe limits

• To ensure the separator will achieve maximum RPM immediately

• To determine if the separator requires additional lubrication

• To verify that the sludge pump is operating continuously

What is the first step when operating a separator in manual mode?

• Start the feed pump and open the sludge discharge valve

• Verify that the oil heater is reaching the correct temperature

• Perform pre-starting checks and ensure valves are set correctly

• Increase the motor speed immediately after switching on power

During manual operation, how can the oil-water interface be adjusted?

• By changing the separator motor speed

• By adjusting the gravity disk position and monitoring oil discharge

• By increasing the sludge discharge rate

• By closing all water inlet valves to prevent mixing

What should be done if the oil in the separator is too thick for proper separation?

• Increase the oil temperature using the oil heater

• Close the oil discharge valve to allow more time for separation

• Reduce the separator motor speed to slow down the process

• Increase the feed rate to force oil through the system

Which electrical component plays a key role in controlling the separator’s automatic functions?

• The feed pump motor

• The control panel with sensors and actuators

• The sludge tank heating element

• The water discharge valve

Why is it necessary to perform a shutdown procedure after separator operation?

• To allow the motor to cool down before the next cycle

• To ensure that the oil and sludge discharge lines remain clean

• To prevent residual oil or sludge from affecting the next operation

• To reduce the risk of electrical faults when restarting the system
