A submersible well pump works by pushing water to the surface, offering high pressure and flow rate while being fully immersed in the water.
Here's a breakdown of how it works:
- Immersion: The pump is designed to be submerged inside the well.
- High Pressure & Flow Rate: It can deliver water at a high pressure and flow rate, even from significant depths (according to the [YouTube video reference][]).
- Mechanism: Instead of sucking water, the submersible pump pushes the water to the surface. While the reference doesn't explicitly detail the internal mechanism, submersible pumps typically use a series of impellers and diffusers.
- Impellers: Rotating blades that increase the water's velocity and kinetic energy.
- Diffusers: Stationary components that convert the kinetic energy into pressure.
- Multi-Stage Design: Many submersible well pumps use a multi-stage design, with multiple impeller/diffuser sets stacked on top of each other, further increasing pressure output.
Here's how the process typically unfolds:
- Water Enters: Water enters the pump through a screen, preventing large debris from entering and damaging the impellers.
- Impeller Rotation: The motor spins the impellers, accelerating the water outward.
- Pressure Increase: As the water passes through the diffusers, its velocity is reduced, and the pressure increases.
- Discharge: The pressurized water is then forced upwards through the drop pipe to the surface.
