High Quality Air Cooled Dry Oil Free Screw Vacuum Pump for Lab Vacuum Distillation
Product description
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.
An oil-free vacuum pump is a type of pump that does not use lubricants in the chamber to generate vacuum or cool the pump. It achieves gas suction and vacuum creation through specific mechanical structures and working principles. Due to not using oil as a lubricant, it avoids oil pollution and oil vapor emissions, which meets environmental requirements. The oil-free design reduces the maintenance cost of the pump and extends its service life. Due to its unique performance and advantages, oil-free vacuum pumps are widely used in multiple fields.
Turbovacuum pumps use the rotation of the turbine to extract gas. A limited working chamber is formed between the turbine and the pump chamber. When the turbine rotates, the gas in the working chamber is discharged and new gas is sucked in. Molecular sieve adsorption vacuum pump utilizes the adsorption effect of molecular sieve on gas to achieve suction. Molecular sieves have a highly porous structure and can selectively adsorb gas molecules. When the molecular sieve is saturated with adsorption, it is released by heating to restore its adsorption capacity.
The reciprocating vacuum pump achieves gas suction through the reciprocating motion of the piston in the pump chamber. When the piston moves outward, the gas in the pump chamber is discharged; When the piston moves inward, the pump chamber is open to the atmosphere and draws in more gas. By continuously repeating this process, the effect of continuous suction is achieved. Liquid ring vacuum pump is similar to reciprocating vacuum pump, but uses liquid as the working medium. There is an eccentric wheel in the pump chamber. When the eccentric wheel rotates, the liquid will form a circulation along the inner wall of the pump chamber, and the gas is sucked in and discharged through the volume change of the liquid ring.
