Improved structure of the vertical suspended semi submersible vertical turbine pump 

An improved vertical suspended semi submersible vertical turbine pump structure, comprising a motor frame, an upper shaft, and a lower shaft. The motor frame is connected to a water outlet bend pipe, and the left end of the water outlet bend pipe is located at the bottom of the motor frame and connected to a bearing box. The left end of the bearing box is connected to a bearing cover, and a journal is set between the bearing cover and the outer circle of the upper shaft. The left end of the journal is limited by a hanging nut and fixed twice by a bolt; A packing box is provided between the outlet bend pipe and the outer circle of the upper shaft, and the left end of the packing box is fixed to the packing cover by bolts. A packing shaft sleeve is provided between the packing cover and the outer circle of the upper shaft, and an oil seal is provided on the outer circle of the packing shaft sleeve. This technical method has a compact structure, stable operation, simple operation, and an integrated water outlet bend for easy installation. The combination of the packing box and oil seal makes the probability of medium leakage from the pump almost zero, with good sealing effect, safety, and environmental protection.
