A lower support structure for a suspended semi submersible vertical turbine pump


This relates to a component structure of a suspended semi submersible vertical turbine pump, specifically a lower support structure of the suspended semi submersible vertical turbine pump. The lower support structure of the suspended semi submersible vertical turbine pump includes a pump body and an impeller installed inside the pump body, and a sliding bearing is provided above the impeller shaft; The lower end of the impeller shaft is installed on a bearing seat through a lower bearing, which is connected to the pump body through a section of cylinder; There are suction ports that run through the inner and outer walls of the cylinder. Compared with traditional structures, this technology adds a lower bearing device to provide positioning support for both the upper and lower parts of the impeller, ensuring minimal radial runout during operation, while reducing axial force during impeller operation, minimizing wear on sliding bearings and shaft sleeves, and reducing maintenance costs; At the same time, by setting a suction port on the wall of the cylinder, the requirements for setting the suction port are solved. The setting of the tongue can avoid the phenomenon of vortex flow and improve the anti blocking performance of the inlet. During pump operation, the inlet is in a negative pressure state, reducing the impact of liquid flow on the lower bearing sealing device and improving the sealing performance of the bearing body.
