Understanding the Components

To comprehend how a submersible well pump works, it’s essential to understand its key components. The main parts include:

  • Motor: This is typically located at the bottom of the pump and is responsible for driving the impellers.
  • Impellers: These are rotating blades that move water through the pump.
  • Discharge Head: The part of the pump that pushes the water up to the surface.
  • Pump Shaft: This connects the motor to the impellers.
  • Electrical Cable: Supplies power to the motor from the surface.

Step 1: Installation and Positioning

Proper installation is crucial for a submersible well pump. Follow these steps:

  1. Select an appropriate location in the well for the pump.
  2. Ensure the pump is submerged in water, typically at least a few feet below the water level.
  3. Connect the discharge pipe to the well and route it to the desired location.
  4. Attach the electrical cable that powers the motor.

Step 2: Powering the Pump

Once installed, the next step is powering the pump:

  1. Connect the electrical cable to the power source on the surface.
  2. Ensure that all electrical connections are secure to prevent failures.
  3. Turn on the power supply to activate the motor.

Step 3: Water Movement Mechanism

Now, let's look at how the pump actually moves water:

  1. When the motor receives power, it starts to run.
  2. The motor drives the pump shaft, which rotates the impellers.
  3. The rotating impellers create a suction effect, drawing water into the pump.
  4. The design of the impellers pushes the water upward through the discharge head.

Step 4: Water Delivery

The final step is delivering water to the intended location:

  1. As water is pushed through the discharge head, it flows into the attached pipe.
  2. The water then travels up to the surface, where it can be accessed through a tap or plumbing system.
  3. Make sure to monitor the flow rate to ensure it's meeting your needs.

Maintenance and Troubleshooting

To keep the submersible well pump functioning efficiently, consider regular maintenance:

  • Inspect electrical connections for wear and tear.
  • Check the pump for any blockages or debris.
  • Test the water pressure to ensure the system is operating optimally.

Conclusion

A submersible well pump operates using a straightforward process: it utilizes an electric motor to drive impellers that pull and push water from deep underground up to the surface. Understanding the components and operating steps can help maintain the system for long-term use.
