A vacuum water pump works by creating a vacuum to draw water into a chamber and then using compression to expel the water. Here’s a breakdown of the process:
Working Principle Explained
The primary function of a vacuum water pump relies on cyclical changes in pressure within a sealed chamber. The steps involved are:
-
Vacuum Generation: The process starts with the expansion of a sealed chamber. This expansion creates a vacuum (a space with significantly reduced pressure).
-
Intake: The vacuum pulls fluid (water, in this case) through the intake valve and into the chamber. The pressure difference between the outside environment (higher pressure) and the chamber (lower pressure) is what forces the water in.
-
Chamber Filling: The chamber continues to expand and fill with water until it reaches its full expansion capacity.
-
Valve Switching: Once the pump is fully expanded and the chamber is full (or nearly full) of water, the intake valves close to prevent backflow. Simultaneously, the exhaust valve opens.
-
Compression and Exhaust: As compression occurs within the chamber, the fluid (water) is forced out through the exhaust valve. The reduction in volume within the chamber increases the pressure, pushing the water out.
Summary Table
| Step | Description | Valve Status |
|---|---|---|
| Vacuum Generation | Sealed chamber expands, creating a vacuum. | Intake Open |
| Intake | Vacuum pulls fluid (water) through the intake valve into the chamber. | Intake Open |
| Chamber Filling | Chamber fills with water. | Intake Open |
| Valve Switching | Intake valve closes, and exhaust valve opens. | Intake Closed, Exhaust Open |
| Compression | Chamber compresses, forcing water out through the exhaust valve. | Exhaust Open |
