Vertical suspended semi submersible self regulating long axis sewage sump pump

At present, most suspended semi submersible vertical turbine pumps are processed in sections due to the long pump shaft, which is difficult to machine. However, due to the long size of the shaft, it is difficult to control the radial runout, which increases the gap between the pump shaft and the sliding bearing, making it difficult to maintain a fixed gap and affecting the normal use of the pump. The composition of this vertical suspended semi submersible self-adjusting long axis sewage sump pump technology method includes: a motor seat (1), a motor (11) installed on the top of the motor seat, a motor coupling connected to a universal joint, the lower end of the universal joint connected to the pump coupling, and the pump coupling connected to the pump shaft. The upper end of the pump shaft is equipped with paired tapered roller bearings, and the lower end of the pump shaft is equipped with rolling ball bearings. The pump body is connected to the suction pipe (9) and the outlet pipe (10) respectively. This technical method is used for vertical self-adjusting long axis sewage sump pumps.
