Abstract
The utility model provides a submersible motor. The submersible motor includes a motor housing, an upper end ring, a bolt, an upper guide bearing pedestal, a connecting flange and a cover-shaped nut, wherein the upper end ring is embedded in the motor housing; the upper guide bearing pedestal is installed on the upper end ring in a pressed manner; the connecting flange is installed on the upper guide bearing pedestal in a pressed manner; the bolt fixes the connecting flange, the upper guide bearing pedestal and the upper end ring are fixed on the motor housing from the above. The submersible motor is characterized in that an O-shaped ring, a press sleeve and two Teflon press rings are added; one of the Teflon press rings, the O-shaped ring, the other one of the Teflon press rings and the press sleeve are sleeved on the bolt successively from bottom up; and the bolt is installed in a bolt hole in the center of the connecting flange in a pressed manner through the cover-shaped nut. According to the utility model, a sealing body is composed of the one of the Teflon press rings, the O-shaped ring, the other one of the Teflon press rings and the press sleeve in a combined manner. The submersible motor can bear sealing load reaching up to 20MPa and is good in working performance.
