Essential Interview Questions For Cavity Pump Operator
1. Explain the working principle of a cavity pump?
A cavity pump operates on the principle of progressive cavity. It consists of a single helical rotor and a double helical stator. The rotor and stator are made of elastomeric materials and fit together with a close tolerance. As the rotor turns, it creates a series of cavities between itself and the stator. These cavities progress along the length of the pump, moving the fluid from the inlet to the outlet.
2. What are the advantages of using a cavity pump?
High efficiency
- Cavity pumps are highly efficient because they have a positive displacement design. This means that they do not rely on the velocity of the fluid to create pressure, which results in less energy consumption.
Gentle pumping action
- Cavity pumps have a gentle pumping action, which makes them ideal for pumping shear-sensitive fluids. The elastomeric materials used in the rotor and stator create a seal that prevents the fluid from being damaged.
Low maintenance
- Cavity pumps are low maintenance because they have a simple design and few moving parts. The elastomeric materials used in the rotor and stator are wear-resistant, which extends the life of the pump.
3. What are the different types of cavity pumps?
- There are two main types of cavity pumps: open throat and closed throat.
- Open throat pumps have a clearance between the rotor and stator, allowing solids to pass through the pump without damaging it.
- Closed throat pumps have a tight fit between the rotor and stator, which prevents solids from passing through. This type of pump is used for pumping clean fluids.
4. What are the factors to consider when selecting a cavity pump?
- The flow rate and pressure requirements of the application.
- The type of fluid being pumped.
- The presence of solids in the fluid.
- The temperature of the fluid.
- The space available for the pump.
5. How do you maintain a cavity pump?
- Regularly inspect the pump for wear and tear.
- Replace the rotor and stator as needed.
- Lubricate the pump according to the manufacturer’s instructions.
- Keep the pump clean and free of debris.
6. What are the common problems that can occur with cavity pumps?
- Wear and tear of the rotor and stator.
- Clogging of the pump with solids.
- Loss of prime.
- Overheating of the pump.
7. How do you troubleshoot a cavity pump that is not working properly?
- Check the power supply to the pump.
- Inspect the pump for leaks.
- Check the flow rate and pressure of the pump.
- Inspect the rotor and stator for wear and tear.
- Clean the pump if it is clogged with solids.
8. What are the safety precautions that should be taken when operating a cavity pump?
- Never operate a pump that is not properly grounded.
- Do not work on a pump that is running.
- Wear appropriate personal protective equipment, such as gloves and safety glasses.
- Keep the work area clean and free of hazards.
9. What is the difference between a cavity pump and a centrifugal pump?
- Cavity pumps are positive displacement pumps, while centrifugal pumps are velocity pumps.
- Cavity pumps have a high efficiency, while centrifugal pumps have a lower efficiency.
- Cavity pumps have a gentle pumping action, while centrifugal pumps have a more aggressive pumping action.
- Cavity pumps can be used to pump fluids with solids, while centrifugal pumps cannot.
10. What is the difference between a cavity pump and a reciprocating pump?
- Cavity pumps are rotary pumps, while reciprocating pumps are positive displacement pumps.
- Cavity pumps have a continuous flow, while reciprocating pumps have a pulsating flow.
- Cavity pumps are more compact than reciprocating pumps.
- Cavity pumps can be used to pump fluids with solids, while reciprocating pumps cannot.
