Essential Interview Questions For Pumper
1. Explain the difference between a centrifugal pump and a positive displacement pump?
A centrifugal pump and a positive displacement pump are essentially different in their operating principles:
- Centrifugal pump: Uses rotating impellers to create centrifugal force, which accelerates the fluid outward from the center of the pump. The velocity of the fluid increases as it moves away from the center, and this increased velocity creates pressure, which forces the fluid through the discharge port. Centrifugal pumps are typically used for high-flow, low-pressure applications.
- Positive displacement pump: Uses a variety of mechanisms, such as pistons, gears, or diaphragms, to trap and move a fixed volume of fluid. The volume of fluid displaced by the pump is directly proportional to the speed of the pump. Positive displacement pumps are typically used for low-flow, high-pressure applications.
2. Describe the different types of centrifugal pumps?
Single-stage pumps
- Single-stage pumps use a single impeller to raise the pressure of the fluid. They are typically used for low-pressure applications.
Multi-stage pumps
- Multi-stage pumps use multiple impellers to raise the pressure of the fluid. They are typically used for high-pressure applications.
End-suction pumps
- End-suction pumps have the suction port located at the end of the pump. They are typically used for applications where the fluid level is above the pump.
Side-suction pumps
- Side-suction pumps have the suction port located on the side of the pump. They are typically used for applications where the fluid level is below the pump.
Vertical pumps
- Vertical pumps have the shaft positioned vertically. They are typically used for applications where the pump must be submerged in the fluid.
3. What are the different types of positive displacement pumps?
- Reciprocating pumps: Use a piston or diaphragm to move the fluid. Reciprocating pumps are typically used for high-pressure applications.
- Rotary pumps: Use rotating gears or vanes to move the fluid. Rotary pumps are typically used for low-pressure applications.
4. How do you calculate the flow rate of a pump?
The flow rate of a pump is calculated using the following formula:
- Q = V * N
- where:
- Q = flow rate (in gallons per minute)
- V = volume of fluid displaced by the pump per revolution (in gallons per revolution)
- N = speed of the pump (in revolutions per minute)
5. How do you calculate the head of a pump?
The head of a pump is calculated using the following formula:
- H = P / (SG * g)
- where:
- H = head (in feet)
- P = pressure (in pounds per square inch)
- SG = specific gravity of the fluid
- g = acceleration due to gravity (in feet per second squared)
6. How do you select the right pump for a particular application?
The following factors should be considered when selecting a pump for a particular application:
- Flow rate
- Head
- Fluid type
- Temperature
- Pressure
- NPSH
7. What is NPSH?
- NPSH stands for Net Positive Suction Head. It is the minimum pressure that must be maintained at the suction port of a pump to prevent cavitation.
8. What is cavitation?
- Cavitation is the formation of vapor bubbles in a fluid due to a decrease in pressure. Cavitation can damage the pump and reduce its performance.
9. How do you troubleshoot a pump that is not working properly?
- Check the power supply to the pump.
- Check the pump for leaks.
- Check the impeller for damage.
- Check the bearings for wear.
- Check the seals for leaks.
10. What is your experience with pumps?
- I have worked with pumps for over 10 years. I have experience with a variety of pumps, including centrifugal pumps, positive displacement pumps, and submersible pumps. I have also experience with troubleshooting and repairing pumps.
