Title:
STRUCTURALLY IMPROVED MAGNETIC DRIVE PUMP
Document Type and Number:
WIPO Patent Application WO/2017/008738
Kind Code:
A1
Abstract:
The present invention relates to a structurally improved magnetic drive pump. A first tapered roller bearing (8) is cooperatively mounted between an inner wall of a pump body (1) and an impeller (2), and a pump spindle (7) is mounted inside a pump cavity under the support of a second tapered roller bearing (9). The magnetic drive pump with this structure can effectively control the poor dynamic balance of the impeller (2) and effectively control the axial end play of the pump spindle (7) and the impeller (2), thereby increasing the durability of the magnetic drive pump in use and improving the operational reliability and safety of the magnetic drive pump.
