TH176290B - "Vertical pump" - Google Patents

Abstract

The invention relates to a vertical shaft type pump that Even for high capacity pumps Help to change Bearings that are easily immersed Without lifting the pump When the pump is in position And improve the reliability of bearings being immersed. This vertical shaft type pump is provided with a guide shell (1), a suspended pipe (3), a guide shell suspension (1) inside the water tank (5), a supply bend pipe (4) at Is connected to the top end of the suspension tube (3), the impeller (10), which is coupled inside the guide shell (1) and the rotating shaft (6), in which the impeller (10) is fixed, the rotating shaft (6) is Rotatable supported by the immersed bearing unit (12) and external bearing (11), the immersed bearing unit (12) is positioned under the impeller (10) and supported the lower end of the rotating shaft ( 6) The rotating shaft (6) protrudes from the external bearing (11) through the impeller (10) without protrusion through the bearing other than the external bearing (11) .The immersed bearing unit (12) has a bearing. An internal contact supporting the sliding part of the rotating shaft (6) on the bearing surface along the inner ring and having an external contact bearing supporting the sliding part of the rotating shaft (6) on the outer circumferential surface of the bearing. Bearing

Claims (1)

1. A vertical pump consisting of an impeller, a rotating shaft that extends through the impeller, and in which the impeller is bolted, an external bearing that supports the rotating shaft and the shaft.
