Understanding how water pumps work can be among the most exciting endeavours for physics and engineering enthusiasts. While many excellent models and types have already dominated the market today, one can be made certain that improved models can still be invented in the mind through a basic review of the concepts involved.
There are various water pump types which are in use today either in residential or in commercial buildings or both. It will be helpful for one to be able to familiarize the mechanisms of each.
One type is called the well pump which is basically a more fundamental type of pump. The source is underground water, hence it can be inferred that the liquid had to be pushed upward in order to deliver water into the tank or container. In distributing from the tank to the household faucets, the tank would have to act as a water pump itself. Anyway, well pumps are most common in households. Since they are driven by electricity through a motor, the household may suffer from temporary loss of water supply when power surges come, though.
Another, but more general, classification of pumps is called centrifugal pumps. These pumps are used to convey not only water but also other liquids which are relatively thin. The main characteristic of centrifugal pumps is that they are operated by means of one or more impellers. An impeller is simply a rotating motor within a machine, and it is designed to initialise fluid movement by rotation. When impellers are used for centrifugal pumps, the term “centrifugal” will find better meaning in the minds of the learning ones. Indeed, centrifuges move about in a rotational manner, hence the name. When a desired pressure difference is reached by the centrifugal mechanism of the pump, the liquid will then be conveyed as designed. Centrifugal pumps encompass widely diversified types, and are thus common in both residential and commercial buildings.
While not really water pumps, positive displacement pumps are also widely used types and have a few similarities with centrifugal pumps. They do not usually convey water since they are designed for thicker or more viscous fluids. Positive displacement pumps do not make use of impellers; instead, they rely on other rotating or reciprocating parts to create the desired pressure difference. Clearly, these types are of more use in industrial settings rather than the residential ones.
In the end, it can be said that the enthusiast has certainly been amazed with the intelligibility of the concepts discovered and the applications made out of those concepts. He is then challenged to further be thinking outside of the box and trying to make more innovations out of those that have already been established. Who knows if he gets to invent the next model of pumps Australia will be most honoured of?
