【発明の名称】自吸式液体リングポンプの運転方法および装置
Document Type and Number:
Japanese Patent JP2553551
Kind Code:
B2
Abstract:
Stalling of liquid ring pumps during start-up is prevented, without the need for a separate liquid pump or other means for initiating or sustaining the flow of make-up pumping liquid into the pump, by providing a bypass conduit for initially conveying some pumping liquid from the relatively high liquid pressure side of the pump to the relatively low liquid pressure side of the pump. This helps the pump establish the internal liquid distribution needed to form a viable liquid ring and create the gas pressure differential necessary to initiate and sustain the inflow of make-up pumping liquid.
