The Science behind a Vacuum Pump
The science behind a vacuum pump was first developed in the 1700’s and was developed mostly for scientific research. A vacuum was created in an enclosed surface to study the effects of gasses and electricity without air being a part of the study. As technology developed, inventions were created to make use of this newly found vacuum pump.
When most people think of a vacuum pump, they think of the vacuum cleaner itself. It is true that a vacuum uses a vacuum pump but that is not the only use for a vacuum pump. Vacuum pumps exist in many items, from cars to microwave ovens. The use for each vacuum pump varies from one mechanical device to another.
In the case of an actual vacuum, the pump is in fact the motor with the rotating fan attached to it. The fan itself has curved blades, which brings air up and into the vacuum cleaner. As the fan rotates faster and faster with the help of the electric motor, the fan pushes air faster into the vacuum. The semi suction that is created helps to take in air, as well as dirt and dust from most surfaces. This is how vacuum cleaners work.
Imagine for a moment sucking liquid up a straw. As you drink, your mouth becomes a vacuum pump, the device that creates the vacuum and the pressure needed to push liquid up and out of the cup and into your mouth. It is the same principle with most anything that creates a sort of vacuum. Even fans that are built to keep you cool create a vacuum as it pumps air through; it sucks air from the back to bring air moving fast into the front.
For vacuum cleaners, the vacuum pump is the basis of most vacuums. The suction that the vacuum pump creates helps to clean surfaces. In some cases, the vacuum pump may need replacing if the vacuum cleaner does not clean as well as it once did and the filters have already been checked for cleanliness. This could mean that the motor isn’t pushing the fan fast enough to create that semi vacuum that helps to suck up air, dirt and other particles.
Replacement vacuum pumps for vacuum cleaners can be found in most hardware shops, through the manufacturer of the vacuum, and through online retail sources. There are many models of vacuum pumps so it is necessary to match the right vacuum pump model to the correct brand.
Often when the vacuum pump itself goes out, the entire vacuum cleaner ends up being replaced and the old vacuum is thrown out. This is always an option but it could be an expensive one. Replacing the entire vacuum would usually cost more than it would to simply replace the vacuum pump. In most cases you can replace the vacuum pump yourself. Instructions are usually prepared or you can find assistance online or through calling the manufacturer’s customer service number. In any case you can usually find someone who will be able to repair your vacuum and replace the pump at minimal charge.
