Abstract

PURPOSE: In a thrust bearing of a canned motor pump, to automatically adjust the position of its rotating disc by providing water paths which run toward the opposed side wall and intersects each other on the periphery of the rotating disc.
CONSTITUTION: During operation of a pump, when a rotating disc 1 of a thrust bearing gets near the side wall 3b of a housing 3 for example, the inlets of 7b... of the water paths 7a..., and 7b... which are opened on the periphery of the rotating disc 1 and run from one side wall to the other so as to intersect each other are blocked by a peripheral wall 3c. Thereby, a water from a feed water port 6 which opens to the housing 3 in the circumferential direction of the rotating disc 1 at right angles to a shaft 4 is flushed towards a thrust shoe 2b. The rotating disc 1 is moved by the water pressure so that the shoe 2b is detached from the side wall 3b, by which the rotating disc 1 is automatically controlled to be put approximately in the center position of the housing 3.
