Description
The application is applied for the day 20201 month 20 days, the application number: 202010065072.X, named: the "pressure-resistant motor" is filed separately.
Technical Field
The present invention relates to a motor structure, and more particularly, to a pressure-resistant motor.
Background
If it is desired to agitate, e.g. mix, the pressure vessel, then typically fan blades are provided in the pressure vessel. The motor for driving the fan blade may be installed at the outside of the pressure vessel, referring to fig. 1, the fan blade F is installed at the inside of the pressure vessel T, the rotation axis a of the fan blade F extends to the outside of the pressure vessel T, the motor M is installed at the outer wall surface of the pressure vessel T, and the motor M is covered by the outer cover C. In addition, the motor for driving the fan blade may be installed inside the pressure vessel, referring to fig. 2, the fan blade F is installed inside the pressure vessel T, and the motor M for driving the fan blade F is also installed inside the pressure vessel T.
In the structure of fig. 1, since the rotation shaft a of the motor M must extend from the outside of the pressure vessel T into the inside of the pressure vessel T, it is necessary to open at the wall surface of the pressure vessel T for the rotation shaft a to pass through. However, since such an opening structure is likely to cause leakage of the pressure vessel T, the motor M is covered with the cover C to attempt to reduce leakage. However, the cover C may cause a problem that the motor M cannot dissipate heat, resulting in easy damage of the motor M.
In the structure of fig. 2, since the motor M is directly installed in the pressure vessel T, although the problem of leakage can be avoided, the problem of heat dissipation of the motor M still cannot be solved, and in other cases, the fluid in the pressure vessel T may damage the circuit structure of the motor, such as the coil.
In either the configuration of fig. 1 or 2, the thickness of the motor M and the pressure vessel T at each location is not specified, which results in waste of overused material or insufficient thickness to damage the barrel by fluid pressure.

The seal case body wall thickness Tc, the pressure vessel body wall thickness Tc, the back cover plate thickness Te and the pressure vessel end plate thickness Te are all thicknesses.

Referring to the embodiment shown in fig. 9B, in the present embodiment, the pressure vessel inner diameter R1 of the pressure vessel T is smaller than the seal housing inner diameter R2 of the seal housing 10 of the pressure-resistant motor 100. Therefore, the seal case body wall thickness Tc of the seal case body 122 of the seal case 10 is larger than the pressure vessel body wall thickness Tc of the pressure vessel body T3 of the pressure vessel T, and the back cover plate thickness Te of the back cover 123 of the seal case 10 is larger than the pressure vessel end plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T. The rear cover plate thickness Te of the rear cover 123 of the seal housing 10 is larger than the seal housing body wall thickness Tc of the body 122 of the seal housing 10, and the pressure vessel end plate thickness Te of the pressure vessel end plate T4 of the pressure vessel T is larger than the pressure vessel body wall thickness Tc of the pressure vessel body T3 of the pressure vessel T.
In other words, in fig. 9B, the seal housing inner diameter R2 of the seal housing 10 is larger than the pressure vessel inner diameter R1 of the pressure vessel T, the thickness of the seal housing 10 (i.e., the seal housing thickness Tc of the seal housing body 122) is larger than the thickness of the pressure vessel T (i.e., the pressure vessel thickness Tc of the pressure vessel body T3), and the thickness of the end plate of the seal housing 10 (i.e., the back cover plate thickness Te of the back cover 123) is larger than the thickness of the end plate of the pressure vessel T (i.e., the pressure vessel end plate thickness Te of the pressure vessel end plate T4), the thickness of the seal housing 10 (i.e., the seal housing thickness Tc of the back cover 122) is smaller than the thickness of the end plate of the seal housing 10 (i.e., the back cover plate thickness Te of the back cover 123), and the thickness of the pressure vessel T (i.e., the pressure vessel thickness Tc of the pressure vessel body T3) is smaller than the thickness of the end plate of the pressure vessel T (i.e., the pressure vessel end plate thickness Te of the pressure vessel end plate T4).
In summary, in the embodiment shown in fig. 9A and 9B, in other words, the seal housing inner diameter R2 of the seal housing 10 is different from the pressure vessel inner diameter R1 of the pressure vessel T, the thickness of the shaft of the seal housing 10 (i.e., the seal housing shaft wall thickness Tc of the shaft 122) is different from the thickness of the shaft of the pressure vessel T (i.e., the pressure vessel shaft wall thickness Tc of the pressure vessel shaft T3), and the thickness of the end plate of the seal housing 10 (i.e., the back cover plate thickness Te of the back cover 123) is different from the thickness of the end plate of the pressure vessel (i.e., the pressure vessel end plate thickness Te of the pressure vessel end plate T4). Of course, in other embodiments, it is also possible that the seal housing inner diameter R2 of the seal housing 10 is the same as the pressure vessel inner diameter R1 of the pressure vessel T, the thickness of the shaft of the seal housing 10 (i.e., the seal housing shaft wall thickness Tc of the shaft 122) is the same as the thickness of the shaft of the pressure vessel T (i.e., the pressure vessel shaft wall thickness Tc of the pressure vessel shaft T3), and the thickness of the end plate of the seal housing 10 (i.e., the back cover plate thickness Te of the back cover 123) is the same as the thickness of the end plate of the pressure vessel (i.e., the pressure vessel end plate thickness Te of the pressure vessel end plate T4).
