It is to be understood that the fluid 700 is not limited to oil for sealing, and other forms of fluid 700 are possible as long as they can be used for sealing. Illustratively, the fluid 700 may also be water or an oil-water mixture.

In one embodiment, referring to fig. 2, 3 and 10, the rotor assembly 100 further includes an impeller 6 mounted on the rotating shaft 1, the impeller 6 rotates along with the rotating shaft 1, and the impeller 6 is located at an end of the container 3 away from the first mounting base assembly 2.

In one embodiment, referring to fig. 2, 3 and 10, the impeller 6 is located at the lower end of the rotating shaft 1.

Under such operating conditions, the rotor assembly 100 of the embodiment of the present application can reduce the degree of corrosion of the components in the first mount base assembly 2 to some extent.

In one embodiment, the material of the container 3 may be an elastic material. Thus, when the maximum outer diameter of the sealing portion 21 is larger than the outer diameter of the mounting opening 321, the elastic material of the container 3 is advantageous in that the sealing portion 21 can be smoothly mounted in the accommodating cavity 31 of the accommodating portion 3 or dismounted from the accommodating cavity 31 of the container 3.

In one embodiment, the elastic material may be rubber or silicone.

In one embodiment, the material of the container 3 may also be a material having no elastic deformation capability.

In one embodiment, referring to fig. 4, 5 and 9, the container 3 is formed with a flow restriction portion 32 above the accommodating cavity 31, the flow restriction portion 32 is annular and surrounds the first mounting seat assembly 2, the flow restriction portion 32 is surrounded by a mounting opening 321, and the mounting opening 321 is located inside the accommodating cavity 31. With such a structure, when the container 3 is rotated by the rotation shaft 1, the fluid 700 in the accommodating chamber 31 is radially thrown to the side of the container 3 and flows upwards under the action of centrifugal force, and the flow restriction portion 32 can restrict the fluid 700 in the accommodating chamber 31 from flowing upwards to some extent.

In an embodiment, the flow restriction portion 32 may not be provided, and it is only necessary to control the rotation speed of the rotating shaft 1 to prevent the fluid 700 from being excessively centrifuged in the accommodating chamber 31 and being thrown out of the accommodating chamber 31.

In one embodiment, referring to fig. 4, 5 and 9, the container 3 is formed with a connecting portion 33 sleeved on the rotating shaft 1, the connecting portion 33 is hermetically connected with the rotating shaft 1, and the connecting portion 33 is located at the bottom of the accommodating cavity 31. With such a configuration, the fluid 700 in the housing chamber 31 can be prevented from leaking from between the connecting portion 33 and the rotating shaft 1 by gravity to some extent, and the possibility that the corrosive gas 600 penetrates into the housing chamber 31 from between the connecting portion 33 and the rotating shaft 1 and moves through the gap between the first mount assembly 2 and the rotating shaft 1 can be reduced, thereby reducing the degree of corrosion of the components in the first mount.

In one embodiment, the connecting portion 33 is in interference fit with the rotating shaft 1.

In an embodiment, referring to fig. 4, fig. 5 and fig. 9, the rotating shaft 1 penetrates through the installation hole 321 and the accommodating cavity 31, and the rotating shaft 1 is disposed in the connecting portion 33.

In one embodiment, referring to fig. 4 to 8, the maximum outer diameter of the sealing portion 21 is not smaller than the diameter of the mounting hole 321. With such a structure, since the maximum outer diameter of the sealing portion 21 is not smaller than the diameter of the mounting port 321, when the second gap 5 is sealed by the fluid 700 in a state where the rotating shaft 1 is rotating, the fluid 700 can be substantially limited in the accommodating cavity 31 and located outside the mounting port 321 according to actual needs, and the fluid 700 can be as far away from the mounting port 321 as possible, even if the rotating speed of the rotating shaft 1 is high, and the centrifugal force of the container 3 on the fluid 700 generated by the rotation of the rotating shaft 1 is large, it is difficult to throw the fluid 700 out of the accommodating cavity 31 through the mounting port 321, so that the second gap 5 can be well sealed by the fluid 700 and is substantially not limited by the rotating speed of the rotating shaft 1.

In one embodiment, the maximum diameter of the sealing portion 21 may be smaller than the diameter of the mounting opening 321.

In one embodiment, referring to fig. 4 to 8, the sealing portion 21 includes a first sealing portion 211 and a second sealing portion 212; the first sealing portion 211 is annular and surrounds the rotating shaft 1, and the first gap 4 is a gap between the bottom of the first sealing portion 211 and the bottom wall of the accommodating chamber 31. The second sealing portion 212 is annular and surrounds the first sealing portion 211, the second gap 5 is a gap between the outer side of the second sealing portion 212 and the inner side wall of the accommodating chamber 31, and the outer diameter of the second sealing portion 212 is not smaller than the diameter of the mounting opening 321. With such a structure, when the rotation of the rotating shaft 1 and the container 3 is stopped, the fluid 700 is located at the bottom of the container 3, and the first gap 4 is sealed by the fluid 700, so that the corrosive gas 600 is prevented from flowing to the gap between the first sealing part 211 and the rotating shaft 1 through the first gap 4, and the degree of corrosion of the parts in the first mounting seat assembly 2 is reduced. When the container 3 rotates along with the rotating shaft 1, the fluid 700 is thrown to the side wall of the container 3 under the action of centrifugal force, and the second gap 5 is sealed by the fluid 700, so that the corrosive gas 600 is prevented from flowing to the gap between the first sealing part 211 and the rotating shaft 1 through the second gap 5 and the first gap 4, and the degree of corrosion of parts in the first mounting seat assembly 2 is reduced. Since the first sealing portion 211 has a smaller outer diameter to facilitate the fluid to enter the accommodating cavity 31 through the mounting opening 321, and since the second sealing portion 212 surrounds the first sealing portion 211, the outer diameter of the second sealing portion 212 is not smaller than the diameter of the mounting opening 321, so that the radial outer edge of the second sealing portion 212 can be located outside the mounting opening 321, when the fluid 700 is thrown toward the sidewall of the container 3 by the centrifugal force, the fluid 700 thrown toward the sidewall of the container 3 can be better sealed against the second sealing portion 212 and the container 3 even outside the mounting opening 321, the fluid 700 can be far away from the mounting opening 321 as far as possible, and the fluid 700 can be prevented from being thrown out of the accommodating cavity 31 through the mounting opening 321. The arrangement of the first and second sealing parts 211 and 212 enables the sealing part 21 to prevent the fluid 700 inside the receiving chamber 31 from overflowing through the mounting port 321 with a simple structure.

In an embodiment, the second sealing portion 212 may not be provided, the bottom end of the first sealing portion 211 is inclined outward so that the bottom end of the first sealing portion 211 is located outside the mounting opening 321, and the fluid 700 is located outside the mounting opening 321, so that the second gap 5 can be sealed, thereby preventing the fluid 700 in the accommodating chamber 31 from being thrown out through the mounting opening 321.

In an embodiment, the second sealing portion 212 may not be provided, the first sealing portion 211 may extend in the vertical direction and may not be inclined outward, and the second gap 5 is a gap between the outer side of the first sealing portion 211 and the inner side wall of the accommodating chamber 31.

In an embodiment, the second sealing portion 212 and the flow restriction portion 32 may not be provided, the first sealing portion 211 may extend in the vertical direction and may not be inclined outward, and the second gap 5 is a gap between the outer side of the first sealing portion 211 and the inner side wall of the accommodating chamber 31.

In an embodiment, referring to fig. 4 to 8, the first mounting base assembly 2 includes a first vibration damping device 22 and a first base 23, the first vibration damping device 22 is sleeved on the rotating shaft 1, the first base 23 is at least partially sleeved on the first vibration damping device 22, and the first base 23 is at least partially located in the accommodating cavity 31, so that the first base 23 and the container 3 are sealed by a fluid 700. Structural style like this can cushion the vibration that the pivot 1 rotated the arouse to a certain extent, reduces the vibration of pivot 1 and transmits to first pedestal 23.

In one embodiment, the first vibration damping device 22 may not be provided.

In one embodiment, the sealing portion 21 is formed on the first seat 23.

In one embodiment, the first sealing portion 211 and the second sealing portion 212 are formed on the first seat 23.

In one embodiment, referring to fig. 7, the first base 23 forms a working cavity 231 for mounting the first vibration damping device 22.

It is understood that the volume of the fluid 700 in the containing chamber 31 is too large, which may cause the fluid 700 to overflow during the rotation of the container 3 along with the rotating shaft 1, and the volume of the fluid 700 in the containing chamber 31 is too small, which may prevent the fluid 700 from sealing between the bottom of the sealing portion 21 and the container 3 when the rotating shaft 1 and the container 3 stop rotating. In view of this, in one embodiment, the volume of the accommodating cavity 31 in the height range of the first gap 4 is a first preset volume, and the volume of the rotating shaft 1 in the height range of the first gap 4 is a second preset volume; the difference between the first preset volume and the second preset volume is a first target volume, and the volume of the fluid 700 is not less than the first target volume; the volume of the accommodating chamber 31 outside the mounting port 321 is a second target volume, and the volume of the fluid 700 is not greater than the second target volume. With such a structure, the volume of the fluid 700 is not less than the first target volume, and when the rotation shaft 1 and the container 3 stop rotating, the fluid 700 at the bottom of the accommodating chamber 31 can contact or even overflow the bottom of the sealing part 21, so that the fluid 700 at the bottom of the accommodating chamber 31 can be sealed with respect to the first gap 4. The volume of the fluid 700 is not greater than the second target volume, so that the accommodating chamber 31 has enough space at the outer side of the mounting port 321 to accommodate the fluid 700, and it can be avoided that the space of the accommodating chamber 31 at the outer side of the mounting port 321 is small, which causes the excessive fluid 700 to overflow from the mounting port 321 in the rotation state of the rotating shaft 1.

It can be understood that the volume of the receiving cavity 31 outside the mounting opening 321 is: the volume of the accommodating chamber 31 minus the volume of the portion of the accommodating chamber 31 inside the mounting port 321.

In one embodiment, referring to fig. 5 and 9, the height dimension of the first gap 4 is h₁The height dimension of the accommodation chamber 31 is h₂The diameter of the accommodating cavity 31 is D, and the diameter of the rotating shaft 1 is D₁The diameter of the mounting opening 321 is d₂The first predetermined volume isThe second predetermined volume isThe first target volume isThe volume of the accommodating chamber 31 isThe volume of the portion of the accommodation chamber 31 inside the mounting opening 321 isThe second target volume isThe volume of fluid 700 is V, and the range of volumes of fluid 700 is expressed as:

it should be noted that "+" in the above formulas refers to a product in mathematical calculation, not a convolution.

In this way, the rotating shaft 1 in the rotor assembly 100 rotates, and the impeller 6 rotates along with the rotating shaft 1 to make the delivery pump work and pump corresponding corrosive materials, such as disinfectant. Since the fluid 700 in the housing chamber 31 seals the first gap 4 when the rotation shaft 1 stops rotating and seals the second gap 5 when the rotation shaft 1 rotates, the degree of corrosion of the components in the first mount assembly 2 can be reduced.

In one embodiment, referring to fig. 2, the impeller 6 is located at the lower end of the rotating shaft 1.

Therefore, the bearings 7 in the first mount assembly 2 and the second mount assembly are less affected by the corrosive gas 600, and the degree of corrosion of the bearings 7 in the first mount assembly 2 and the second mount assembly can be reduced.
