High vacuum pumps are designed to run at higher speeds and pressures than traditional vacuum pumps. A high vacuum pump is required for any use where pressure ratings and pump speeds are beyond the capabilities of a traditional vacuum pump. Many manufacturers require the use of high vacuum pumps to complete vital industrial processes in a variety of industries and processes. High vacuum pumps manufacturers typically make three different types of high vacuum pumps for a variety of different uses, including turbomolecular pumps, cryo pumps, and oil diffusion pumps. Each pump has its own unique uses that make it the ideal choice for different industrial applications.
I spent one year as a Rotary Youth Exchange student in Mexico. While there I was able to live with three different Mexican families, learn Spanish, go to school and participate in cultural celebrations such as the Mexican Independence Day and Flag Day. I ate as much Mexican food as humanly possible, from tostadas to tacos to enchiladas to burritos to quesadillas and so on and so forth. I traveled extensively throughout the country and absolutely fell in love with it. Another aspect of Mexican culture and tradition that I learned to appreciate was tequila.
Doubling as both a vacuum pump and a gas compressor, water sealed vacuum pumps are versatile. Water is used as a source of energy in order to compress the gas. A vacuum is created as water is pumped through a cylinder-shaped rotor. As the pump spins as a result of the vacuum, the process of gas compression begins.
Lubricated vacuum pumps remind me of the phrase “well oiled machine,” for something that runs smoothly, without many kinks and not making much noise. The exact opposite of a lubricated vacuum pump is the oil less vacuum pump. The main difference being one uses oil and is considered a wet pump and the other doe not use oil and is considered a dry pump. A low vapor pressure oil is used in the wet pump’s pumping mechanism. Oil liquid and vapor must both exist in the pump’s vacuum volume in order to function properly.
In the mid 1600s, a German mayor of a small town performed a trick using 2 metal half-spheres and a team of sixteen horses to entertain some houseguests. It was the first time he put his invention-a piston and air gun cylinder with two-way flaps designed to pull air out of whatever vessel it was connected to-to use in front of other people. The mayor, named Otto von Guericke, joined the two copper hemispheres together and pumped the air out using his contraption. He then harnessed eight horses to each half. The result? An astonished audience, completely inseparable copper hemispheres and the very first demonstration of a vacuum pump. It didn’t take long for this trick to gain popularity, and Guericke began performing in the German court with more and more horses. The power of a vacuum quickly caught the eye of scientists, who began using vacuum pumps to study properties of gasses and electricity. Today, you’d be hard pressed to find a single industrial factory or experimentation facility that doesn’t use a vacuum pump.
