In this, we will tell you about how does a water pump work. The water pump can be defined as the pump which uses the principles like mechanical as well as hydraulic throughout a piping system and to create sufficient force for its future use. At present these pumps are utilized within the wide range of housing, farming, municipal, and the manufacturing applications.
How Does a Water Pump Work
- There are other types of the water pump, however, the positive displacement varieties, such as the manually operated piston pumps which are often found in parks, as well as developing countries.
- Positive displacement pumps work by trapping water from a central reservoir and then forcing its volume upwards into a discharge pipe.
- This is achieved through the use of a valved piston and cylinder, which when merged, draw water via suction up into the cylinder, before redistributing it through a descending valved piston head into an expanding higher chamber.
- When the piston begins to rise, its own valve is forced shut by increased pressure within the higher cylinder chamber, while the cylinder’s reservoir valve is pulled open by a release of pressure in the lower chamber.
- This empowers the pockets of water to be continuously drawn up from an underground source to an outlet on the surface.
- Historically, water pumps were invented to optimize the retrieval of water from town wells, which previously had employed simple but labor-intensive bucket-on-rope methods.
Water Pump Parts
- Force rod – The external lever of the pump, the user must apply force to this rod to draw the piston up and down the cylinder.
- Check valves – The check valves are one-way, non-return valves, and allow water to pass through first from the reservoir and second through the piston head on its journey to the surface.
- Cylinder – The vertical body of pump, the cylinder offers an enclosed compartment for the pump’s piston to move through.
- Piston – The piston descends and ascends through the cylinder, with water from lower chamber forced through its head valve via a boost in pressure.
- Reservoir – The mediating tank or chamber where the pump’s water is stored ready for extraction.
