More Information
Summary:The invention discloses a built-in boosting device of a centrifugal water pump. The built-in boosting device can compress a vacuum low-pressure area at the side position of an impeller in the centrifugal water pump through a first gas compression pipe, a second gas compression pipe and an air compression ball arranged in the built-in boosting device when the centrifugal water pump performs boosting work; in the process that the pressure intensity is gradually increased, the sealing performance in an inner cavity of the centrifugal water pump can be improved through the arranged sealing boosting auxiliary mechanism, and it is guaranteed that the sealing strength in the inner cavity of the centrifugal water pump can meet the requirement for increasing of the pressure intensity; and therefore, the problem of air leakage caused by pressure intensity rise is solved, normal boosting work is ensured, and the working efficiency and the working economic benefit of the centrifugal water pump areensured. 本发明公开了一种离心水泵内置升
