Abstract
A pump mounting structure of a canned submersible motor for a deep well pump is disclosed. The motor comprises a stator chamber and bearing brackets provided on opposite sides of the stator chamber. The bearing bracket on a load side of the motor includes a pump mounting flange for supporting the pump thereon. The improvement consists of a pump suction port being formed in the load side bearing bracket to thereby make the load side bearing bracket serve as a pump suction casing, and of the pump mounting flange being constituted as a pump body mounting flange. By this means, heat generated in the stator chamber is dissipated efficiently by the water passing through the suction port provided in the bearing bracket. Also, as a pump suction casing is not necessary, an axial length of the pump can be shortened and the number of parts can be reduced.
