[0038] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0039] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0040] It should also be understood that, although the present application has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0041] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0042] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0043] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0044] The gas in the explosion-proof area on the compressor side is not allowed to exchange and communicate with the air on the motor side in the non-explosion-proof area, so it is necessary to set a bulkhead seal at the place where the coupling passes through to ensure that the gas in the explosion-proof area and the non-explosion-proof area is not connected. The bulkhead seal needs to be put on the coupling during installation. At this time, the motor shaft extension end, the gearbox shaft extension end and the bulkhead seal body need to be aligned. Alignment is relatively difficult, and because the bulkhead plate of the cabin may be deformed after welding, coupled with the original processing error, it will make the bulkhead seal more difficult to align with the two devices, and the verticality and sealing effect of the bulkhead seal cannot be guaranteed.

[0045] Figure 1 It is a schematic structural diagram of a compartment sealing compensation device in one embodiment of the present invention; Figure 2It is a schematic diagram of the partial cross-sectional structure of a compartment sealing compensation device in another embodiment of the present invention.

[0046] like Figure 1 to Figure 2 As shown, in one embodiment, the present invention provides a bulkhead sealing compensation device, the bulkhead sealing compensation device includes a bulkhead plate 4, a supporting structure 103, a leg 7, and a compensator 3;

[0047] The bulkhead plate 4 is provided with a through hole 41, and the bulkhead plate 4 is a separation plate between the explosion-proof area 101 and the non-explosion-proof area 102;

[0048] The support structure 103 is fixedly connected to the hull structure;

[0049] One end of the leg 7 is connected to the support structure 103;

[0050] The compensator 3 is arranged on the side surface of one side of the bulkhead plate 4, and the inner hole of the compensator 3 is sleeved with the bulkhead sealing body 5 of the cylinder.

[0051] In this embodiment, a specific structure of a bulkhead seal compensation device is provided. On the one hand, the risk of gas leakage will increase, and the gas in the explosion-proof area will leak to the non-explosion-proof area. On the other hand, if the verticality of the bulkhead seal body cannot be guaranteed, it will accelerate its wear and fail to seal. For this reason, it is considered to design a conventional bulkhead seal to be installed on a mounting ring with compensation and adjustment functions, so that the bulkhead seal can change the installation angle and position, so that when the coupling and the mounting surface are offset at an angle, the compensator can be used for compensation to ensure coaxiality and verticality.

[0052] The processing error of the bulkhead plate 4 is difficult to control, and the bulkhead plate 4 may be deformed again during the welding process with the cabin. That is, the bulkhead sealing body 5 that can be installed and aligned during the assembly process may be deformed during installation on board, and the sealing effect and alignment cannot be guaranteed, thereby affecting the operation of the compressor and increasing the risk of gas circulation on both sides.

[0053] By improving the installation surface of the seal body and changing the bulkhead plate 4 to a compensator, the adjustable range can be maximized to avoid the inability to adjust to the center or vertical position, which causes the seal body to wear faster. However, if the hole processing error on the bulkhead plate 4 is too large, or the pry body is deformed during lifting and installation, it is still possible that the center cannot be adjusted.

[0054] At the same time, it is necessary to consider that when installing the bulkhead sealing body, since the cabin bulkhead is a welded surface, it is impossible to use machining for fine processing, so the compensator needs to consider the verticality of the compensation bulkhead and the coaxiality error of the opening, etc., and at the same time ensure the sealing between the sealing body and the compensator, and the compensator and the bulkhead.

[0055] In one embodiment, the compartment sealing compensation device further comprises a mounting ring 1;

[0056] The mounting ring 1 is mounted on the side surface of the other side of the bulkhead 4 .

[0057] The mounting ring 1 is used to strengthen the strength of the bulkhead 4 .

[0058] In one embodiment, a sealing gasket 2 is provided between the mounting ring 1 and the bulkhead plate 4 , and between the compensator 3 and the bulkhead plate 4 .

[0059] In this embodiment, a method of adjusting the positional relationship between the three is provided by using a sealing gasket 2 .

[0060] In one embodiment, an adjustment pad 14 is provided between the support structure 103 and the leg 7 .

[0061] In this embodiment, the height and tilt angle of the legs 7 are adjusted in detail.

[0062] In one embodiment, the leg 7 and the compensator 3 are connected by bolts 9 .

[0063] In this embodiment, a specific implementation method of fixing with bolts 9 is provided.

[0064] In one embodiment, a coupling is passed through the bulkhead sealing body 5 .

[0065] In this embodiment, a specific implementation method of inserting the coupling into the bulkhead sealing body 5 is provided.

[0066] In one embodiment, the compensator 3 is arranged on the side of the non-explosion-proof area, and the mounting ring 1 is arranged on the side of the explosion-proof area.

[0067] In this embodiment, a specific implementation method of the compensator 3 setting area is provided, which is also convenient for debugging and centering in non-explosion-proof areas.

[0068] In one embodiment, the present invention further provides a ship with a bulkhead sealing compensation device, and the ship includes the bulkhead sealing compensation device.

[0069] In one embodiment, the present invention further provides a method for adjusting a bulkhead sealing compensation device, based on the bulkhead sealing compensation device;

[0070] Adjust the coaxiality and verticality of the compensator and the coupling.

[0071] In one embodiment, after the step of adjusting the coaxiality and perpendicularity of the compensator and the coupling, the method further comprises:

[0072] Adjust the bolts of the legs and the compensator.

[0073] The bulkhead sealing compensator is composed of a mounting ring, a sealing gasket, a compensator, a support leg and an adjustment gasket, which solves the problem that the existing bulkhead sealing device is difficult to adjust during installation, causing the bulkhead sealing position to easily deviate, resulting in accelerated wear of the seal or poor sealing effect.

[0074] To solve the above problems, the present invention is implemented through the following technical solutions:

[0075] First install the bulkhead seal body on the compensator, place the mounting ring on the compressor side, add a sealing gasket between the mounting ring and the bulkhead plate, align it with the opening of the bulkhead plate, pass the coupling through the bulkhead plate, install the compensator on the motor side, add a sealing gasket between the bulkhead plate, connect it with the mounting ring with bolts, install the legs on the compensator with bolts, use the legs and adjusting gaskets to adjust the bulkhead seal body, because the compensator can deflect and stretch within a certain range, the position of the bulkhead seal body can be repeatedly adjusted until the alignment is completed, fix the legs to the base with bolts, and finally tighten all bolts.

[0076] The bulkhead seal body is installed on a mounting ring which can adjust the compensation angle and distance within a certain range to ensure the centering and verticality requirements of the bulkhead seal body and the equipment, reduce the seal friction rate, extend the service life and ensure the sealing effect.

[0077] This patent uses the design of the mounting ring, sealing gasket, compensator, outrigger, and adjustment pad, and utilizes the characteristics of the compensator that can be stretched and deflected, so that the compartment sealing body can be vertical and aligned with the equipment. This reduces the wear of the sealing body, reduces the risk of leakage, and ensures the normal use of the sealing device.

[0078] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
