Surface of contact between described bearing ejection ring and lower bearing gland is sealed by seal ring, and the surface of contact between described bearing pressure ring and upper bearing (metal) gland is sealed by labyrinth seal structure.
Described upper bearing (metal) is roller bearing, and described lower bearing is tapered roller bearing.
Beneficial effect:
All there is limit stoper at bearing inner race upper and lower sides of the present utility model, when rotated, can not there is upper and lower play and cause the axial impact loading of bearing excessive in bearing inner race with pump shaft, lower bearing lost efficacy and causes the situation of the damage of whole pump.
