Improved suspended semi submersible vertical turbine pump

An improved suspended semi submersible vertical turbine pump includes a pump shaft and rubber bearings installed on the pump shaft. The cooling water pipeline of the rubber bearings is connected to the tap water tank through a booster pump. The upper sealing end of the pump shaft is sequentially fitted with a set of first stage mechanical static seal ring, first stage mechanical dynamic seal ring, mechanical seal adjustment spring, second stage mechanical dynamic seal ring, second stage mechanical static seal ring, and mechanical seal end cover from bottom to top. This technical method has high efficiency, stable operation, low equipment maintenance costs, long service life, and simple operation.
