Small Vaccum Pumps Used in Aircraft Cockpits

One of my favorite things to do is fly. I like the experience and excitement that an airplane brings. As the pilot comes on over the intercom system and makes announcements as to how long we will be in the air, at what altitude we will be flying and what the weather is like at our destination, I fidget with excitement and look out the window as we take off and admire the clouds as we glide past them. While I am well aware of the physics and scientific reasoning behind how a plane flies and how it stays in the air, the whole experience, however, makes me wonder in awe.

Small vacuum pumps are used in the aircraft cockpit. An engine-driven vacuum pump drives three gyroscopic instruments found in the cockpit. The three instruments are attitude indicator, turn and bank indicator and gyro compass. The vacuum system is the power source of the attitude indicator and gyro compass. Air is sucked in to the vacuum pump and is used to pump the rotor to make the instruments function. The gyroscopic instruments are used to measure and/or maintain orientation while the aircraft is operating in the air.

Not only are small vacuum pumps used in aircrafts they can be used in a variety of medical and dental procedures where any type of suction is required. They can be found laboratories, out-patient surgery, operating rooms, dental offices and other areas. Small vacuum pumps can also be portable and found on ambulances and in high-risk areas where emergencies may happen such as pools and nursing homes.

Small vacuum pumps are typically made of stainless steel or aluminum because of the materials’ resistance to contamination and durability. They are also made compact and in a variety of different dimensions so they are able to fit in small, hard-to-fit places. Even though small vacuum pumps are smaller than other types of vacuum pumps, it does not mean they are less effective.
