Of course, in other embodiments, the inner diameter R2 of the sealed housing 10 and the inner diameter R1 of the pressure vessel T are the same, and the thickness of the cylinder body of the sealed housing 10 (that is, the sealing of the cylinder body 122 is the same). The shell body wall thickness tc) is the same as that of the pressure vessel T (that is, the pressure vessel body wall thickness Tc of the pressure vessel body T3), and the thickness of the end plate of the sealed shell 10 (that is, the back cover 123 The back cover plate thickness te) is the same as the end plate thickness of the pressure vessel (that is, the pressure vessel end plate thickness Te of the pressure vessel end plate T4).

The pressure-resistant motor of the present invention has a hermetic joint structure with the pressure vessel, and in a structure where the motor is arranged outside the pressure vessel, leakage of the pressure vessel through the structure connected to the pressure-resistant motor can be avoided. In addition, the barrel thickness and end plate thickness of the sealed shell and the pressure vessel follow the aforementioned thickness specifications, and can be applied to sealed shells and pressure vessels of different sizes.

However, the above are only preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the description of the invention, All are still within the scope of the invention patent.
