Dry screw vacuum pump is a vacuum device that uses a pair of screws to rotate synchronously at high speed in the pump housing to produce suction and exhaust effects. Its working principle is to achieve gas suction, compression and discharge by periodically changing the volume between teeth through the rotation of the screw. Dry screw vacuum pump has the following main features:
Oil-free lubrication: Dry screw vacuum pump does not require lubricating oil during operation, so it can provide a clean and oil-free vacuum environment, especially suitable for occasions with high cleanliness requirements, such as electronics, semiconductors, pharmaceuticals and other industries.
Strong adaptability: The pump can extract gases containing a large amount of water vapor and a small amount of dust, and has good adaptability to complex gases such as corrosive gases and condensable vapors.
High efficiency and energy saving: The dry screw vacuum pump has a high ultimate vacuum degree, low power consumption, and has the advantages of energy saving and maintenance-free.
Simple structure: It has few parts, no wearing parts, reliable operation, long life, and easy operation and maintenance.
Widely used: Dry screw vacuum pumps are widely used in chemical industry, metallurgy, electronics, petroleum, aerospace, food, medicine and other fields.
