Aux 1 Unit 12 Q3

1 / 10

Why is it important to check for any potential soft foot condition before operating the pump?

B) To ensure that all motor feet are making even contact with the base, preventing misalignment and undue stress on the motor and pump

A) To increase the alignment precision

D) To decrease the pump's output

C) To improve the motor's efficiency

2 / 10

What is one of the critical checks to perform before operating the pump after the motor alignment is completed?

A) Check for proper shaft alignment using a dial indicator to ensure that the alignment remains within tolerance

B) Start the motor at maximum speed

D) Reduce the load on the pump

C) Disconnect the pump from the motor

3 / 10

What final step should be taken once alignment is completed and verified?

D) Increase the load on the motor

C) Disconnect the motor from the pump

A) Tighten all mounting bolts securely and perform a final check to ensure the alignment has not shifted

B) Start the motor immediately without further checks

4 / 10

Which tool is commonly used to check the initial rough alignment between the motor and the pump?

D) A wrench

A) A hammer

B) A spirit level and a straightedge

C) A screwdriver

5 / 10

What additional check should be made regarding the coupling before using the pump after alignment?

A) Ensure the coupling is properly lubricated and secured, and that there is no excessive wear or damage

C) Rotate the coupling manually to ensure it is not moving

D) Increase the coupling's size

B) Disconnect the coupling from the motor

6 / 10

After the initial rough alignment, what method is typically used for fine alignment?

D) Visual inspection only

B) Using a dial indicator to measure the misalignment between the motor and pump shafts

C) Rotating the motor without any load

A) Tightening all bolts as much as possible

7 / 10

How is horizontal misalignment corrected during motor and pump alignment?

D) By adjusting the pump's impeller

B) By adjusting the position of the motor base horizontally, often using bolts or jacking screws

A) By increasing the load on the motor

C) By reducing the speed of the pump

8 / 10

What is a common method for correcting vertical misalignment during motor and pump alignment?

D) Increasing the pump's speed

B) Adding or removing shims under the motor's feet to achieve the correct height

C) Rotating the motor by hand

A) Adjusting the motor's mounting bolts

9 / 10

Why is it important to rotate the shafts and recheck alignment at various points during the process?

C) To decrease the load on the motor

A) To increase the speed of alignment

B) To ensure the alignment is consistent throughout the rotation, detecting any potential angular misalignment or shaft runout

D) To lubricate the motor

10 / 10

What is the first step in aligning a new motor with an existing pump?

D) Begin operating the pump without alignment

A) Start the motor immediately

C) Disconnect the motor from the pump

B) Ensure that both the motor and pump are securely mounted on their respective bases
