Q&A| Instant Download Pdf
1. Which component is primarily responsible for converting electrical
energy into mechanical energy in a well pump system?
A. Pressure tank
B. Motor
C. Check valve
D. Foot valve
The motor converts electrical energy into mechanical energy to drive
the pump impeller and lift water.
2. What type of pump is most commonly used for deep wells over 25
feet in depth?
A. Centrifugal shallow-well pump
B. Hand pump
C. Submersible pump
D. Jet pump
Submersible pumps are designed to operate underwater in deep well
applications, providing greater efficiency and lift capacity.
3. Which device prevents water from flowing back into the well after it
has been pumped into the system?
A. Pressure switch
B. Check valve
C. Pressure gauge
D. Suction line
A check valve allows water to flow in one direction and prevents
backflow, maintaining system pressure.
,4. What is the primary purpose of a pressure tank in a well pump
system?
A. To filter water
B. To store pressurized water and reduce pump cycling
C. To increase flow rate
D. To reduce water hardness
The pressure tank stores water under pressure which reduces the
frequency of pump starts and stops.
5. What measurement is used to determine how much water a well can
deliver?
A. Pressure
B. GPM (gallons per minute)
C. Voltage
D. Ohms
Gallons per minute quantifies the flow rate a well can produce under
specific conditions.
6. When installing a submersible pump, how far above the well bottom
should it be placed to avoid drawing sediment?
A. 1 foot
B. 5 feet
C. 10 feet
D. 20 feet
Placing the pump about 10 feet above the bottom helps avoid
sediment intake and prolongs pump life.
7. Which instrument is used to measure well depth and water level?
A. Multimeter
B. Pressure switch
C. Flow meter
D. Sounder tape
Sounder tape is lowered into the well to determine the depth to
water and the total depth of the well.
8. What electrical hazard must be protected against in a well pump
installation?
A. Low pressure
B. Ground fault
, C. Chemical corrosion
D. Suction loss
Ground faults can cause shocks or fires, so proper grounding and
protection are critical.
9. Which component activates the pump based on pressure changes in
the system?
A. Flow restrictor
B. Check valve
C. Pressure switch
D. Relief valve
The pressure switch senses pressure changes and signals the pump to
start or stop.
10. What does NEMA stand for in reference to electrical motors?
A. National Energy and Maintenance Association
B. National Electrical Motor Alliance
C. National Electrical Manufacturers Association
D. National Electrical Mechanical Assembly
NEMA is the association that sets standards for electrical equipment
including motors.
11. What condition is indicated by frequent short pump cycles?
A. Low voltage
B. Clean water
C. Incorrect pressure tank precharge
D. Excess flow
Incorrect precharge in the pressure tank causes the pump to start
and stop frequently.
12. Which type of wire is typically used for submersible pump
installations?
A. Aluminum rope
B. Solid copper
C. Triplex submersible cable
D. Coaxial cable
Triplex cable includes conductors and a ground, designed for
submersible pump use.
