A drain pump works by using an electric motor to power an impeller, which creates suction to draw water in and then pushes it out through pipes to a designated drainage area.
Here's a more detailed breakdown:
-
Electric Motor: The heart of the drain pump is an electric motor. When power is supplied, the motor spins.
-
Impeller: The motor is connected to an impeller, a rotating component with vanes or blades. As the impeller spins, it creates centrifugal force.
-
Suction and Water Intake: The spinning impeller generates a low-pressure area (suction) that draws water into the pump housing. The water enters through an inlet.
-
Water Movement: The impeller's rotating blades then catch the water and propel it outwards, increasing its velocity and pressure.
-
Discharge: This pressurized water is forced through an outlet port and into a discharge pipe or hose. The pipe then carries the water to a designated drainage point, such as a storm drain, a septic tank, or a different area of the property.
Simplified Analogy:
Think of a drain pump like a water wheel turned by electricity. The motor makes the wheel (impeller) spin, the spinning wheel scoops up water (creates suction), and then throws the water out and away (discharge).
Types of Drain Pumps:
Drain pumps are used in various appliances and systems. Here are a few examples:
- Washing Machine Drain Pump: Removes wastewater after a wash cycle.
- Dishwasher Drain Pump: Removes dirty water after each wash and rinse cycle.
- Sump Pump: Removes accumulated water from basements or crawl spaces.
