Title:
SIDE RUNNER PUMP
Document Type and Number:
WIPO Patent Application WO/2021/027720
Kind Code:
A1
Abstract:
A side runner pump, comprising a housing (20) and a cover (10) connected to each other, and an impeller (30) accommodated in a pump cavity (201) formed by the cover (10) and the housing (20). The impeller (30) is rotatably supported in the pump cavity (201); the cover (10) is provided with an inlet (11); the housing (20) comprises a base (27) and a side wall (21); an output substantially tangential and communicated with a fluid at the inlet (11) is provided on the side wall (21); an inner cavity cross section (211) of the outlet (210) perpendicular to an air flow direction is non-circular. The side runner pump reduces pressure pulsation caused by the airflow, and thus effectively reduces the noise.
