【発明の名称】遠心ポンプと真空ポンプの組合せ、およびガス分離遠心ポンプの機能を制御する方法
Document Type and Number:
Japanese Patent JP2001525898
Kind Code:
A
Abstract:
The method uses a centrifugal pump impeller (14) and a vacuum pump rotor (44) placed on the same shaft (49). The gas separated in the centrifugal pump from the material to be pumped is discharged from the centrifugal pump. The discharge uses the vacuum pump and a gas outlet duct (26) located between the two pumps. The gas flow in the gas outlet duct between the two pumps is controlled by changing the cross sectional flow area of the gas outlet duct.
