Mieco provides new models of vacuum pumps. Vacuum pump is used to remove gas molecules from a sealed volume so that the partial vacuum can be separated. The first vacuum pump was preceded by the suction pump, which is associated with antiquity.
In the 17th century, the redesigned water pumps with improved versions with measurable vacuums are produced. Pumps are broadly categorized on the basis of three techniques.
–Positivedisplacement pumps use a mechanism to increase the decay that allows gas to flow in from the chamber, insulate the cavity and exhaust it to the atmosphere.
–Momentumtransfer pumps are also called molecular pumps which is used in high speed jets of heavy fluid and high speed rotating blades to knock gas molecules out of the chamber.
–Positivedisplacement pumps are more effective for low vacuums. And momentum transfer pumps in conjunction with one or two positive displacement pumps are the most common configuration used to achieve high vacuums.
