Description

Technical Field

[0001] The utility model relates to the technical field of rotor cores, in particular to a blocking rotor and a rotor pump. Background Art

[0002] At present, rotor cores are all made of metal, and there are many kinds of media transported by rotor pumps. When the working conditions of the transported medium do not allow metal contact, and the rotor core also needs metal support, the rotor core made of pure metal is not applicable. Based on the above situation, a blocking rotor and rotor pump are designed. Summary of the invention

[0004] Rotor core;

[0005] A plug, which is arranged at the tail end of the rotor core;

[0006] A blocking layer made of non-metallic material, the blocking layer covers the surface of the rotor core and the plug;

[0007] The fasteners are inserted into the rotor core through the blocking layer and the plug in sequence, and are used to fix the rotor core on the output end of the external rotor pump.

[0008] Furthermore, it also includes: a sealing ring, which is arranged at the head end of the rotor core.

[0009] Furthermore, the sealing ring and the blocking layer are integrally formed.

[0010] Furthermore, the blocking layer is made of rubber.

[0011] Furthermore, the surface of the fastener is provided with a non-metallic coating.

[0012] According to another embodiment of the utility model, a rotor pump is provided, comprising the blocking rotor of the previous embodiment.

[0013] According to a blocking rotor of an embodiment of the utility model, a metal rotor core is blocked and separated from a conveying medium, so that the conveying medium cannot contact the rotor core, thereby being applicable to conveying conditions where metal contact is not allowed.

[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0019] First, combine Figures 1 to 3 A blocking rotor according to an embodiment of the utility model is described, which is used to block the contact between the conveying medium and the metal rotor core 1, and has a wide range of application scenarios.

[0020] like Figures 1 to 3 As shown, a blocking rotor according to an embodiment of the utility model comprises a rotor core 1, a plug 2, a blocking layer 3 made of non-metallic material and a fastener 4.

[0021] Specifically, Figures 1 to 3 As shown, the plug 2 is arranged at the tail end of the rotor core 1; the blocking layer 3 covers the surface of the rotor core 1 and the plug 2; the fastener 4 penetrates the blocking layer 3 and the plug 2 in sequence and is inserted into the rotor core 1 to fix the rotor core 1 on the output end of the external rotor pump. By setting the blocking layer 3, the contact between the conveying medium and the metal rotor core 1 can be blocked, which is suitable for conveying conditions where metal contact is not allowed.

[0022] Further, if Figures 1 to 3 As shown, a blocking rotor according to an embodiment of the utility model further comprises: a sealing ring 5 , which is arranged at the head end of the rotor core 1 , thereby further ensuring that the conveying medium cannot contact the rotor core 1 .

[0023] Furthermore, in this embodiment, the sealing ring 5 and the blocking layer 3 are integrally formed.

[0024] Furthermore, in this embodiment, the blocking layer 3 is made of rubber material, but is not limited to rubber material, and other non-metallic materials may also be used.

[0025] Furthermore, in this embodiment, a non-metallic coating is provided on the surface of the fastener 4 to prevent the exposed metal part of the fastener 4 from contacting the conveying medium.

[0026] When in use, the plug 2 and the rotor core 1 are first packaged, and then the rubber blocking layer 3 (including the sealing ring 5) is wrapped on the plug 2 and the rotor, and then vulcanized to form a product, and finally fixed to the output end of the rotor pump by the fastener 4.

[0027] As described above, according to an embodiment of the utility model, a blocked rotor blocks and separates the metal rotor core 1 from the conveying medium, so that the conveying medium cannot contact the rotor core 1, thereby being applicable to conveying conditions where metal contact is not allowed.

[0028] The above combined with Figures 1 to 3 A blocking rotor according to an embodiment of the utility model is described. Further, the utility model can also be applied to a rotor pump.

[0029] According to another embodiment of the utility model, a rotor pump is provided, comprising the blocking rotor of the previous embodiment, so that the conveying medium cannot contact with the rotor core 1, thereby being applicable to conveying conditions where metal contact is not allowed.

[0030] It should be noted that, in this specification, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, medium or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, medium or device. In the absence of further restrictions, the elements defined by the sentence "comprises..." do not exclude the existence of other identical elements in the process, method, medium or device including the elements.

[0031] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art. Therefore, the protection scope of the utility model should be limited by the attached claims.
