Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting pumps, in particular to a high-efficiency cutting pump impeller structure. Background Art
[0002] Submersible sewage pumps have increasingly higher requirements for flow capacity. Cutter pumps are widely used in the discharge of sewage containing large impurity particles because of the strong cutting ability of the impeller inlet edge. However, the impellers of current cutter pumps are all semi-open, with low efficiency, and the motor is prone to overpower.
[0003] To this end, we address the above issues and propose a high-efficiency cutting pump impeller structure. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-efficiency cutting pump impeller structure, comprising a front cover plate, blades and a rear cover plate, wherein the front cover plate is provided with a shaft sleeve for installing the front cover plate, and a plurality of blades are distributed around the outer wall of the shaft sleeve, and the rear cover plate is connected to the front cover plate through the shaft sleeve.
[0005] As a preferred solution of the high-efficiency cutting pump impeller structure of the utility model, the front cover plate and the blades are integrally cast.
[0006] As a preferred solution of the high-efficiency cutting pump impeller structure of the utility model, the blades are arranged tilted, and the inclination angle is 45° to 60°.
[0007] Beneficial effects of the utility model: the utility model adds a front cover plate on the basis of a semi-open impeller to form a closed structure, which improves efficiency while ensuring flow performance. Secondly, when installing the blades, it can avoid contact with the sharp blade inlet edge, reduce the possibility of workers being scratched, and effectively solve the problems existing in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following briefly introduces the drawings required for the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. Among them:
[0009] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0010] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0011] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0012] Figure 1 The structure diagram of an embodiment of a high-efficiency cutting pump impeller structure of the utility model is shown in FIG. Figure 1 In this embodiment, a high-efficiency cutting pump impeller structure includes a front cover plate 1, blades 2 and a rear cover plate 3. The front cover plate 1 is provided with a shaft sleeve for installing the front cover plate 1. A plurality of blades 2 are distributed around the outer wall of the shaft sleeve. The rear cover plate 3 is connected to the front cover plate 1 through the shaft sleeve.
[0013] Furthermore, the front cover plate 1 and the blades 2 are integrally cast.
[0014] Furthermore, the blades 2 are tilted, and the tilt angle is 45° to 60°.
[0015] The utility model adds a front cover plate 1 on the basis of a semi-open impeller to form a closed structure, which improves efficiency while ensuring flow performance. Secondly, when installing the blade 3, it can avoid contact with the sharp inlet edge of the blade 3, reducing the possibility of workers being scratched.
[0016] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values (e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.
[0017] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
[0018] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0019] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
