Bearing seat for suspended semi submersible vertical turbine pump with external water-cooled chamber

The bearing seat of a suspended semi submersible vertical turbine pump with an external water-cooled chamber includes a motor, a pump shaft, a bearing seat, and a bearing cover. Its characteristic is that the bearing seat, the bearing cover, and the bearing sleeve tightly integrated with the shaft fix the rolling bearing and the thrust bearing, and form a relatively sealed chamber structure; The external connecting pipe of the bearing seat is equipped with a cover plate horizontally on the upper end surface of the external connecting pipe, and a bottom plate on the lower end surface of the external connecting pipe. Both the cover plate and the bottom plate are tightly connected to the bearing seat, forming a sealed cavity; The upper part of the external connecting pipe is equipped with an inlet, and the lower part is equipped with an outlet. The purpose of this technical method is to use an external circulation water-cooled chamber to achieve temperature control of bearings and their internal grease.

Technical requirements: 1. A bearing seat for a suspended semi submersible vertical turbine pump with an external water-cooled chamber, comprising a motor (31) and a pump shaft (3), characterized in that the bearing seat (1), bearing cover (2), and bearing sleeve (32) tightly combined with the pump shaft (3) fix the rolling bearing (301) and thrust bearing (302), and form a relatively sealed chamber structure; The outer connecting pipe (101) is provided on the outside of the bearing seat (1), and the upper end surface of the outer connecting pipe (101) is horizontally provided with a cover plate (102), and the lower end surface of the outer connecting pipe (101) is provided with a bottom plate (103), and both the cover plate (102) and the bottom plate (103) are tightly connected to the bearing seat (1), forming a sealed cooling chamber (11); The upper part of the external connecting pipe (101) is provided with an inlet (105), and the lower part is provided with an outlet (104). A bearing sleeve (41) is provided between the bearing cover (42) and the rolling bearing (4).
