Sealing structure of rolling bearings for suspended semi submersible vertical turbine pump
The rolling bearing sealing structure of a suspended semi submersible vertical turbine pump relates to the sealing structure of a suspended semi submersible vertical turbine pump, which includes an outer connecting pipe and an ear seat set on the outer surface. The ear seat is set at the coupling connection of the pump shaft, and the bearing seat is connected to the ear seat by bolts, and the bearing seat is inside the outer connecting pipe; The interior of the bearing seat is equipped with rolling bearings that cooperate with the pump shaft. The lower rolling bearing is equipped with a sealing element. The top of the bearing seat is equipped with a bearing cover, and a sealing element is provided between the bearing cover and the pump shaft; A bearing sleeve is provided between the bearing cover and the bearing. The purpose of this technical method is to provide a suspended semi submersible vertical turbine pump rolling bearing sealing structure, which changes the sliding bearing to a rolling bearing, uses grease lubrication, and sets up a sealing structure to avoid wear caused by impurities in the medium; At the same time, ensure smooth transmission.
Technical requirements: 1. A suspended semi submersible vertical turbine pump rolling bearing sealing structure, comprising an outer connecting pipe (1) and an ear seat (2) arranged on the outer surface, the ear seat (2) being arranged at the connection of the coupling (31) of the pump shaft (3), characterized in that a bearing seat (21) is connected to the ear seat (2) through bolts, and the bearing seat (21) is inside the outer connecting pipe (1); The interior of the bearing seat (21) is equipped with a rolling bearing (4) that cooperates with the pump shaft (3), and the lower rolling bearing (4) is equipped with a sealing element (6). The top of the bearing seat (21) is equipped with a bearing cover (42), and a sealing element (6) is installed between the bearing cover (42) and the pump shaft (3); A bearing sleeve (41) is provided between the bearing cover (42) and the rolling bearing (4).
