Description

Technical Field

[0001] This application belongs to the field of pump mechanical seal protection technology, and in particular relates to a modular pump mechanical seal protective cover with adjustable pipe hole position. Background Technology

[0002] In centrifugal pump structures, mechanical seal assemblies are typically installed within mechanical seal seats to seal the pump shaft. Traditional mechanical seal seats are solid cylindrical structures, which are heavy. Furthermore, when the mechanical seal requires external piping to introduce compressed gas or liquid to enhance its sealing performance, or when it needs external piping to discharge leaked liquid, the piping hole positions must be pre-set according to the mechanical seal's structural dimensions. Once manufactured, these positions cannot be adjusted, resulting in poor adaptability and significantly increasing production costs and maintainability. Therefore, it is necessary to solve the aforementioned technical problems. Utility Model Content

[0003] The purpose of this application is to provide a modular adjustable pipe hole position pump mechanical seal protective cover to solve the technical problem of poor adaptability of pump mechanical seal protective covers in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a modular adjustable pipe hole position pump mechanical seal protective cover, comprising:

[0005] A mechanical seal seat, forming a receiving cavity and a plurality of through holes communicating with the receiving cavity;

[0006] A protective cover plate is detachably attached to the surface of the mechanical seal seat and forms a first connecting pipe hole corresponding to the through hole. The first connecting pipe hole is entirely located inside the through hole in the axial direction of the through hole.

[0007] The adjustment assembly includes a blind plate and a pipe hole plate that can be selectively attached to the side of the cover plate opposite to the mechanical seal seat. The blind plate is shaped to close the first pipe hole, and the pipe hole plate is provided with a second pipe hole corresponding to the first pipe hole.

[0008] Optionally, the first connecting hole is an oblong hole.

[0009] Optionally, a plurality of adjustment holes are formed on the orifice plate of the connecting pipe;

[0010] The adjustment hole is elongated and parallel in length to the first connecting pipe hole.

[0011] Optionally, the second connecting hole is entirely located inside the first connecting hole in the axial direction.

[0012] Optionally, the protective cover may be configured in at least two different models depending on the location of the first pipe hole.

[0013] Optionally, the mechanical seal seat is provided with mounting holes for connecting the protective cover plate.

[0014] Optionally, the edge portion of the cover plate forms a plurality of slots corresponding to the positions of the mounting holes, the slots being formed in a preset shape and capable of allowing fasteners inserted into the mounting holes to pass through.

[0015] Optionally, a plurality of evenly distributed heat dissipation holes are also formed on the protective cover.

[0016] The advantages of the modular adjustable pipe hole protective cover for pump mechanical seals provided in this application are as follows: Compared with the prior art, in the pump mechanical seal protective cover provided in this application, the cover plate detachably attached to the surface of the mechanical seal seat forms a first pipe hole communicating with the receiving cavity on the mechanical seal seat. Since the blind plate and the pipe hole plate in the adjustment assembly can be selectively attached to the cover plate, when it is not necessary to connect the external pipeline to the receiving cavity, the blind plate can be connected to the cover plate and the first pipe hole can be closed; when it is necessary to connect the external pipeline to the receiving cavity, the pipe hole plate can be connected to the cover plate and the second pipe hole can communicate with the first pipe hole. In this way, the external pipeline can be conveniently connected to the receiving cavity through the second pipe hole and the first pipe hole. Therefore, the pump mechanical seal protective cover in this embodiment can achieve a flexible adaptation effect, which is far superior to the prior art. Attached Figure Description

[0029] Please refer to the following: Figures 1 to 6 The modular adjustable pipe hole position pump mechanical seal protective cover provided in this application embodiment will now be described. The pump mechanical seal protective cover includes a mechanical seal seat 100, a cover plate 200, and an adjustment assembly. Wherein:

[0030] The mechanical seal seat 100 forms a receiving cavity 101 and a plurality of through holes 102 communicating with the receiving cavity 101. This reduces the weight of the mechanical seal seat 100 and saves raw materials. Here, the receiving cavity 101 is used to accommodate and install the mechanical seal assembly. It is understood that the installation and connection method of the mechanical seal assembly can adopt existing technology. The cover plate 200 is detachably attached to the surface of the mechanical seal seat 100 and forms a first connecting hole 201 corresponding to the through hole 102. The first connecting hole 201 is entirely located inside the through hole 102 in the axial direction. The adjustment assembly includes a blind plate 301 and a connecting hole plate 302 that can be selectively attached to the side of the cover plate 200 away from the mechanical seal seat 100. The blind plate 301 is shaped to close the first connecting hole 201. The connecting hole plate 302 is provided with a second connecting hole 321 corresponding to the first connecting hole 201.

[0031] According to the structure provided in this embodiment, in the pump mechanical seal protective cover provided in this embodiment, the cover plate 200 detachably attached to the surface of the mechanical seal seat 100 forms a first connecting hole 201 communicating with the receiving cavity 101 on the mechanical seal seat 100. Since the blind plate 301 and the connecting hole plate 302 in the adjusting assembly can be selectively attached to the cover plate 200, when it is not necessary to connect an external pipe to the receiving cavity 101, the blind plate 301 can be connected to the cover plate 200 and the first connecting hole 201 can be closed; while when it is necessary to connect an external pipe to the receiving cavity 101, the connecting hole plate 302 can be connected to the cover plate 200 and the second connecting hole 321 can communicate with the first connecting hole 201. In this way, the external pipe can be conveniently connected to the receiving cavity 101 through the second connecting hole 321 and the first connecting hole 201, thereby making it convenient for the external pipe to connect to the mechanical seal. Thus, the pump mechanical seal protective cover in this embodiment can achieve a flexible adaptation effect, which is far superior to the prior art.

[0032] It is understood that in embodiments where multiple through holes 102 are provided on the mechanical seal seat 100, multiple protective plates 200 can also be provided. Thus, blind plates 301 or pipe hole plates 302 can be selectively connected to different protective plates 200. This allows blind plates 301 and pipe hole plates 302 to be connected to the same mechanical seal seat 100 respectively, thereby enabling a more flexible adaptation effect for the pump mechanical seal protective cover in this embodiment. For ease of explanation, this embodiment uses the example of two protective plates 200 connected to the mechanical seal seat 100.

[0033] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The first connecting hole 201 is an oblong hole. According to the structure provided in this embodiment, the first connecting hole 201, which is set as an oblong hole, can be more easily adapted to the second connecting hole 321, thus further improving the adaptability of the pump mechanical seal protective cover in this embodiment.

[0034] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 A plurality of adjusting holes 322 are formed on the orifice plate 302. The adjusting holes 322 are elongated and parallel to the length direction of the first connecting hole 201. According to the structure provided in this embodiment, since the length direction of the elongated adjusting holes 322 is parallel to the length direction of the first connecting hole 201, when the orifice plate 302 is connected to the cover plate 200 by fasteners passing through the adjusting holes 322, the relative position of the second connecting hole 321 in the length direction of the first connecting hole 201 can be quickly adjusted by loosening / tightening the fasteners. This allows the second connecting hole 321 to be more flexibly adapted to the target external pipeline, thereby significantly improving the adaptability of the pump mechanical seal protective cover in this embodiment. It is understood that the fasteners described in this embodiment can be bolts or screws commonly used in the art, and will not be described in detail here.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The second connecting hole 321 is entirely located inside the first connecting hole 201 along its axial direction. According to the structure provided in this embodiment, the second connecting hole 321, located inside the first connecting hole 201, ensures good communication with the first connecting hole 201 during adjustment relative to it. This further enhances the adaptability flexibility of the pump mechanical seal protective cover in this embodiment.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The protective cover 200 is formed in at least two different models according to the position of the first connecting hole 201. According to the structure provided in this embodiment, by setting different models of protective cover 200, the first connecting hole 201 formed on the protective cover 200 can be more flexibly adapted to the through hole 102 on the mechanical seal seat 100, which is beneficial to further improve the adaptability of the pump mechanical seal protective cover in this embodiment.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The mechanical seal seat 100 is provided with mounting holes 103 for connecting the protective cover plate 200. According to the structure provided in this embodiment, the mounting holes 103 on the mechanical seal seat 100 make it easier to connect the protective cover plate 200 to the mechanical seal seat 100, which helps to further improve the adaptability of the pump mechanical seal protective cover in this embodiment.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The edge portion of the cover plate 200 forms a plurality of slots 202 corresponding to the positions of the mounting holes 103. The slots 202 are formed in a predetermined shape and allow fasteners inserted into the mounting holes 103 to pass through. According to the structure provided in this embodiment, the slots 202 formed on the edge portion of the cover plate 200 can be inserted into fasteners, allowing the cover plate 200 to be quickly installed and fixed. This further improves the adaptability flexibility of the pump mechanical seal protective cover in this embodiment. It is understood that the fasteners described in this embodiment can be commonly used bolts or screws in the art.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 A plurality of evenly distributed heat dissipation holes 203 are also formed on the protective cover plate 200. According to the structure provided in this embodiment, the plurality of heat dissipation holes 203 formed on the protective cover plate 200 can enable the pump mechanical seal protective cover in this embodiment to achieve a good heat dissipation effect.
