Mini Air Pump
A Mini Air Pump is a pump for pushing air. Examples include a bicycle pump, pumps that are used to aerate an aquarium or a pond via an airstone; a gas compressor used to power a pneumatic tool, air horn or pipe organ; a bellows used to encourage a fire; a vacuum cleaner and a vacuum pump.
All Mini Air Pumps contain a part that moves (vane, piston, impeller, diaphragm etc.) which drives the flow of air. When the air gets moved, an area of low pressure gets created which fills up with more air.
Mini Air Pumps and compressors use very similar mechanisms, and basically perform the same action, but in different fluid regimes. At some point there is a crossover point in terminology, but here are some stereotypes:
• Compressors operate on compressible fluids, typically gases. Pumps operate on fluids, typically liquids, approximated as in-compressible.
• Compressors are intended to develop a very high pressure rise against a closed system; pumps are designed to develop relatively little pressure against a free-flowing system with minimal back-pressure.
• Mini Air Pumps are often used in continuous-flow operation, while many lower-end compressors must have intermittent duty cycles.
• Compressors usually have a feedback sensor to shut off when they reach a desired pressure; pumps have a fixed design and operate freely across their performance curve as conditions change
In 1649, Otto von Guericke invented the spool vacuum air pump. This pump was called Mini Air Pump in 19th century lexicons. Additionally, Guericke’s air pump decreased any potential leaks between the piston and the cylinder by utilizing washers made from leather.
The first effective Mini Air Pump constructed in England for scientific purposes was made in 1658 by Robert Hooke for Robert Boyle.
In 1705, an English scientist by the name of Francis Hauksbee, developed a style of a double-barrelled air pump. Hauksbee’s double-barrelled air pump was used primarily for scientific research, and had the ability to create a vacuum.
- The invention of the Mini Air Pump lead to the invention of the vacuum pump and the vacuum tube. The vacuum tube lead to a revelation in many different areas.
- vacuum pumps are used to manufacture light bulbs, the freeze drying process in the medical, food and biological industries, and the atomic energy industry.
- Compressed air allowed for better and more powerful pneumatic tools that helped the growth of big cities through the process of construction. Many important buildings in today’s days society are possible because of these tools, such as skyscrapers, hotels, tenements, and stadiums.
- through the use of reciprocating pumps, engines were created allowing for the use of automobiles.
The Hill reports that, “HVAC systems, and the contractors who install them, are vital to the economy and our livelihoods. They ensure a fresh food supply and that data centers are operational. They also provide essential comfort and indoor air quality for every home, health care facility, and office building.
An air compressor turns power (gasoline or an electrical motor) into potential energy. This potential energy is stored in a tank and forces air into the tank creating positive pressure. Normally a hose is connected to the tank and then when opened with a valve or switch air is shot out of the hose at high speeds.
One of the oldest ways to pump air. A simple mechanism that consists of a flexible bag that has rigid boards or handles on each side. The bag can be expanded and contracted by working the handles away from each other and together forcing air out of the nozzle.
When the bag is inflated or the handles are pulled away from each other a valve is opened on the side allowing air in. When the handles are pushed together that valve is closed and air is forced out the end.
