Aux 1 Unit 12 Q3

1 / 10

How is horizontal misalignment corrected during motor and pump alignment?

C) By reducing the speed of the pump

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

2 / 10

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

C) Rotating the motor by hand

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

D) Increasing the pump's speed

A) Adjusting the motor's mounting bolts

3 / 10

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

D) Increase the load on the motor

B) Start the motor immediately without further checks

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

C) Disconnect the motor from the pump

4 / 10

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

B) Start the motor at maximum speed

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

C) Disconnect the pump from the motor

D) Reduce the load on the pump

5 / 10

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

C) A screwdriver

D) A wrench

B) A spirit level and a straightedge

A) A hammer

6 / 10

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

D) To lubricate the motor

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

7 / 10

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

D) Begin operating the pump without alignment

C) Disconnect the motor from the pump

A) Start the motor immediately

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

8 / 10

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

A) Tightening all bolts as much as possible

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

D) Visual inspection only

C) Rotating the motor without any load

9 / 10

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

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

D) Increase the coupling's size

B) Disconnect the coupling from the motor

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

10 / 10

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

A) To increase the alignment precision

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

C) To improve the motor's efficiency

D) To decrease the pump's output
