タポンプ。[Scope of Claim for Utility Model Registration] (1) A motor outer casing formed by drawing a steel plate into a cylindrical cup shape, and a motor inner casing formed by drawing a steel plate into a cylindrical cup shape with a smaller diameter than the motor outer casing. a pump casing made by drawing a steel plate, punching out a suction port and a discharge port, and welding a suction pipe and a discharge pipe thereto; and a partition made of a press-formed steel plate for sealing the internal casing of the motor. The motor stator is sandwiched and fixed between the cylinders of the motor outer casing and the motor inner casing, and the motor rotor is mounted inside the motor inner casing together with a pair of front and rear bearings having a slightly larger diameter than the outer diameter of the motor rotor. the rotor shafts are respectively fixed to the bearings, one end of which is extended into the pump casing through the partition plate, and an impeller is coupled thereto, and a cylindrical cup-shaped boss is attached to the partition plate. A part is molded to surround the motor rotor shaft, and one end of the bearing is elastically pressed and fixed at one end side part of the boss part, and the partition plate is welded to an opening of the motor internal casing. A canned motor pump characterized in that the opening end edges of the motor outer casing, the motor inner casing, and the pump casing are integrally welded together. (2) The scope of the utility model registration claim, in which the partition plate is provided with a liquid passage hole for introducing a portion of the handling liquid into the internal casing of the motor, and the motor rotor shaft is provided with a through hole for discharging the handling liquid. The canned motor pump according to item 1. (3) The canned motor pump according to claim 2, wherein a filter is provided in the liquid passage hole of the partition plate.
