The invention relates to the technical field of water-cooled motors, and discloses a fully-sealed
vacuum pump water-cooled motor, which comprises a casing and a rotating rod rotationally penetrating through the casing for connection, an end disc is fixed on the outer side of the casing, a rotor is fixed on the outer side of the rotating rod, the rotor is located on the inner side of the casing, a
stator is fixed on the inner side of the casing, and a shielding sleeve is fixed on the inner side of the casing. A
water pipe penetrates through the interior of the
machine shell, and the fluorescent
powder flushing part is arranged at one end of the
water pipe; the detection part is arranged on the outer side of the rotating rod, penetrates through the end disc and is located on the outer side of the
machine shell; the injection protection part is arranged on the outer side of the
machine shell, is connected with the end disc and extends into the detection part; the cooling water carries
fluorescence before entering the
water pipe, the
ultraviolet lamp arranged on the outer side of the machine shell is used for translation during regular inspection, the machine shell is continuously irradiated in the translation process, and the
ultraviolet lamp is used for enabling the
fluorescence carried in the cooling water leaked from the small
water leakage point of the machine shell to emit light, so that the
water leakage point is conspicuous, and the
water leakage effect is improved. The inspection efficiency is improved.
