Oil free vacuum pumps draw air into the pump through specific mechanical structures such as molecular pumps, dry screw pumps, etc. Compress the gas inside the pump to reduce its volume and increase pressure. The compressed gas is discharged from the pump through the exhaust pipe to form a certain negative pressure, thereby achieving a vacuum effect. Oil free vacuum pump is an environmentally friendly, efficient, and reliable vacuum pump equipment widely used in multiple fields. During the selection and use process, it is necessary to pay attention to relevant matters to ensure its normal operation and extend its service life.

The vacuum pump extracts gas from the container being pumped through different mechanisms, thereby creating and maintaining a vacuum state in the space. According to the different working principles, vacuum pumps are mainly divided into two categories: gas capture pumps and gas transfer pumps. Gas capture pumps mainly capture gas molecules through physical or chemical means, such as molecular sieve adsorption vacuum pumps; Gas transfer pumps, on the other hand, transmit gas from one location to another through mechanical movements such as rotation and reciprocating motion, such as reciprocating vacuum pumps and turbine vacuum pumps.
