Positioning mechanism for vertical suspended semi submersible vertical turbine pump

The positioning mechanism for a vertical suspended semi submersible vertical turbine pump includes a motor frame, adjusting nuts, keys, bolts, bearing bodies, bolts, bearing discs, radial bearings, shafts, bolts, bearing sleeves, angular contact ball bearings, and bolts. Its feature is that a positioning ring is installed on the shaft below the motor frame, and a rubber buffer pad is installed on the shaft between the positioning ring and the radial bearing at the bottom of the motor frame. Its characteristics are: the positioning ring is a circular ring structure with a thickness h of 18-25mm, an inner diameter equal to the outer diameter of the shaft, a gap with a width of 2mm on the plane, a countersunk hole and a through hole are machined above the gap, and a threaded hole is machined below the gap. The positioning ring is fixed to the shaft by screws passing through the countersunk hole and the through hole. The advantage of this technical method is that it can position the entire rotor and prevent it from being lifted upwards. The rubber buffer pad serves as a buffer to prevent the radial bearings from being damaged by impact. So the mechanism effectively prevents the rotor from lifting upwards and avoids damage to the bearings.
