Abstract
Disclosed is a multistage centrifugal acid-resisting clean water pump for drainage of a coal bed in a mine. An existing drainage pump is low in drainage efficiency due to poor balancing effect. The multistage centrifugal acid-resisting clean water pump comprises a rotating shaft (19), the left end of the rotating shaft is fixed on a front cover (21) via a left bearing part (1), the front cover is connected with a water inlet section shell (4), a primary impeller (6) is mounted on the rotating shaft in the water inlet section shell and is connected with a secondary impeller (10), a middle section shell (9) is arranged outside the secondary impeller which is connected with a water outlet section impeller (13), a water outlet section shell (17) is mounted outside the water outlet impeller and is connected with a tail cover (18), and the tail cover is connected with a right bearing part (20) which is mounted on the rotating shaft. The multistage centrifugal acid-resisting clean water pump is used for drainage of the coal bed in the mine.
