Internal Structure
Working Principle
The screw vacuum pump employs a sophisticated design that uses a pair of intricately engineered screws rotating in opposite directions within the pump casing. This high-speed, synchronized reverse rotation creates a powerful suction and exhaust mechanism. Each of the two screws undergoes precise dynamic balance correction and is supported by robust bearings, ensuring they are securely mounted within the casing. Notably, there is a specific clearance between the screws, which eliminates friction during operation. The results are impressive: smooth operation, low noise levels, and the ability to efficiently expel substantial amounts of water vapor along with minimal dust-laden gases. The pump's higher vacuum capability and lower power consumption contribute to its energy-saving and maintenance-free benefits. These attributes make our screw vacuum pump the ideal choice for industries with stringent clean vacuum requirements, including pharmaceuticals, chemicals, semiconductors, and food packaging.
