Impeller bearing support structure of cooling water intake pump

摘要

This is designed to be related to cooling water pump to make reprisals specified water supply (mainly water) from power plant, and more specifically, the pump impeller supporting structure for accommodating the water of beginning improves the vibration that the reliability reduction pump impeller of sikieo pumps. ;Thus, suction air chamber's cooling water entrance (1), it is installed to a motor (2) axis 3 of the front end of impeller (4), for holding pump shaft 3, a upper bearing (metal) (5) and impeller (4) in the cool, keeping and impeller includes that the water pump structure of a upper bearing (metal) quantity of the catch makes 6, by the impeller that lower bearing expands to the front end of 4 axis 3 there is a lower bearing housing 7 to be mounted on suction air chamber (1) (8) and has been kept impeller (4) equipped with reward, certain hajjok.
