Problems solved by technology

[0003] Under the premise of the same base size and the same number of poles, the length of the iron core of the submersible motor increases with the increase of power, and the outer diameter of the rotor is much smaller than the outer diameter of the motor. The outer diameter is 10 times or even larger. When the submersible motor is installed horizontally or obliquely, the rotor of the motor will be deflected and deformed under the influence of its own gravity, which will cause the air gap between the stator and rotor to be uneven, and the vibration of the motor will be large.
When the bending becomes large enough, the outer circle of the rotor will rub against the inner hole of the stator, causing sweeping, until the motor is burned

Abstract

The invention relates to a horizontal type submersible motor which comprises a shaft, a rotor and a stator. The motor is characterized in that the rotor comprises upper and lower rotors; the shaft comprises an upper second step circular truncated cone connected to the upper rotor, a lower second step circular truncated cone connected to the lower rotor, a first step circular truncated cone positioned between the upper second step circular truncated cone and the lower second step circular truncated cone, an upper third step circular truncated cone positioned in the upper end of the upper secondstep circular truncated cone, a lower third step circular truncated cone positioned in the lower end of the lower second step circular truncated cone, an upper cooperation part positioned in the upper end of the upper third step circular truncated cone and cooperated with an upper guiding bearing, and a lower cooperation part positioned in the lower end of the lower third step circular truncatedcone and cooperated with a lower guiding bearing; the external diameter of the first step circular truncated cone is greater than that of the upper second step circular truncated cone; the external diameter of the first step circular truncated cone is greater than that of the lower second step circular truncated cone; the external diameter of the upper second step circular truncated cone is greater than that of the upper third step circular truncated cone; and the external diameter of the lower second step circular truncated cone is greater than that of the lower third step circular truncatedcone.

Description

technical field [0001] The invention belongs to the technical field of submersible pumps, in particular to a horizontal submersible motor. Background technique [0002] Due to its simple structure, reliable operation, long service life, convenient maintenance, and high performance index, the submersible motor is widely used in industry, agriculture, mining, oil exploration and other fields, and has become an ideal driving force for water supply and drainage. . The submersible motor is generally designed as a slender structure due to the requirements of the installation well diameter, and its length is much larger than its diameter. Mostly used for vertical installation. With the changes in the use environment and other factors, more and more users require horizontal installation and use. [0003] Under the premise of the same frame size and the same number of poles, the length of the iron core of the submersible motor increases with the increase of power. The outer diamet...
