Abstract
Description
Technical Field
[0001] This utility model relates to the field of split-case pump technology, and in particular to a split-case pump structure with adjustable flow rate under multiple operating conditions, variable operating conditions, and pump equipment performance modification. Background Technology
[0002] Currently, because most existing split-case pump housings are made of one-piece casting, the throat area of the housing is a fixed value, which leads to the problem that they are not suitable for scenarios with multiple or variable flow rates.
[0003] In view of the problems existing in the above-mentioned prior art, it is necessary to study and design a new type of adjustable flow split-case pump structure to overcome the problems existing in the prior art. Summary of the Invention
[0004] The existing split-case pump housings, as described above, are mostly integrally cast, with a fixed throat area. This results in their unsuitability for various operating conditions with varying flow rates. Therefore, this invention provides a split-case pump structure with adjustable flow rate. This invention primarily achieves different operating flow parameters for the pump by adapting flow adjustment levers with varying flow areas.
[0005] The technical means adopted in this utility model are as follows:
[0006] An adjustable flow split-case pump structure includes: an upper pump body and a lower pump body;
[0007] Furthermore, an installation groove is provided at the position of the tongue separating the upper pump body and the lower pump body;
[0008] Furthermore, the installation slot is equipped with a replaceable flow regulating block, which can be replaced according to the working conditions to achieve different flow parameter requirements.
[0009] Furthermore, flow regulating blocks are divided into two structures: bridge-type blocks and non-overlapping blocks.
[0010] Furthermore, the flow regulating piston is limited and prevented from rotating by anti-rotation pins and a rectangular / square shape.
[0011] Furthermore, the flow regulating piston can be divided into one or a combination of cylindrical, rectangular, or other shapes.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. The adjustable flow split-case pump structure provided by this utility model can realize different operating flow parameters of the pump equipment by adapting the flow adjustment lever with different flow areas.
[0014] 2. The adjustable flow split-case pump structure provided by this utility model improves the interchangeability of split-case pump molds, reduces manufacturing costs, and has good economic benefits.
[0015] 3. The adjustable flow split-case pump structure provided by this utility model does not change the external dimensions of the pump and is suitable for performance modification of pump equipment.
[0016] In summary, the technical solution of this utility model solves the problem that existing split-case pump housings are mostly made of one-piece casting, and the throat area of the housing is a fixed value, which makes them unsuitable for various operating conditions with different flow rates.

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0027] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0028] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0029] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0031] The flow regulating block 3 is divided into two structures: bridge-type block and non-overlapping block.
[0032] The flow regulating block 3 uses anti-rotation pins and a rectangular / square shape to limit and prevent rotation.
[0033] The flow regulating block 3 is available in one or a combination of cylindrical, rectangular, or other shapes.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
