Description

Technical Field

[0001] The utility model relates to the technical field of axial flow pumps, in particular to an axial flow pump mounting disc structure. Background Art

[0002] Axial-flow pumps are fluid conveying equipment widely used in a variety of fields, including water conservancy, agricultural irrigation, urban water supply and drainage, and industrial circulating water systems. Their structural design, installation, and commissioning are crucial to the stable operation of the entire system. Traditional axial-flow pumps typically consist of multiple components, including the pump body, impeller, guide vanes, shaft, and bearings. These components must meet stringent precision requirements during installation and commissioning to ensure pump performance and reliability.

[0003] The structural characteristics of traditional axial flow pumps dictate that during the installation and commissioning process, measurements of multiple surfaces, lines, and points are required. For example, the installation plane of the pump body needs to be horizontal, which involves horizontal measurements at multiple measurement points; the relative positional relationship between the impeller and the guide vanes needs to be determined by measuring specific surfaces and lines, including the coaxiality of the centerline of the impeller hub and the centerline of the guide vanes, as well as the clearance between the impeller blades and the guide vanes. These measurements often need to be performed at multiple different angles and cross-sections. In addition, factors such as the verticality of the shaft and the installation height of the bearing seat also require precise measurement, making the entire measurement work complex and involving a large number of measurement points, lines, and surfaces.

[0004] Due to the numerous measurement elements involved, commissioning becomes extremely tedious and laborious. Adjusting the pump level may require repeated readjustment of the anchor bolts and gaskets. Fine-tuning the coaxiality and clearance between the impeller and guide vanes may require repeated disassembly and reassembly. Furthermore, each adjustment step requires re-measuring the relevant elements to ensure accuracy. This extensive commissioning effort not only requires significant manpower and time, but also places high demands on the technicians' technical proficiency and experience.

[0005] The complexity of these measurements and commissioning processes directly leads to delays in product installation and commissioning. In large-scale water conservancy or industrial projects, the installation and commissioning of axial flow pumps often impacts the overall project duration. Furthermore, the tedious commissioning process reduces efficiency and increases installation and commissioning costs. For example, if an axial flow pump is urgently needed during the irrigation season, prolonged commissioning can delay irrigation operations, resulting in losses such as delayed crop irrigation. In industrial circulating water systems, this can disrupt normal production, leading to economic losses.

[0006] In summary, these problems of the traditional axial flow pump structure during the installation and commissioning process seriously restrict its application efficiency and effect. There is an urgent need for a new technical solution to simplify the installation and commissioning process and improve work efficiency and quality. Utility Model Content

[0007] The purpose of this utility model is to provide an axial flow pump mounting disc structure that can easily align the centers of the motor and pump when installing them. During the adjustment process, the operator can more accurately control the relative position of the pump and motor to ensure the consistency of the centers of the two. This precise adjustment capability makes the pump more reliable and stable during operation, effectively reducing the occurrence of failures. At the same time, after assembly is completed, the horizontality of the coupling end face is automatically consistent with the horizontality of the pump foundation, and the center of the coupling also coincides with the rotation center of the pump main shaft, greatly reducing labor costs and installation time, improving overall work efficiency, and making the product more competitive in the market.

[0008] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an axial flow pump mounting disc structure, comprising a first disc half-sleeve and a second disc half-sleeve; the first disc half-sleeve and the second disc half-sleeve are covered together to form a disc sleeve; the top of the disc sleeve is inclined to provide a slide surface for use with a plurality of steel balls; the lower end face of the coupling of the axial flow pump is pressed against the steel balls located on the slide surface; the bottom of the disc sleeve is respectively provided with stop portions that cooperate with the packing components; the disc sleeve is positioned and installed on the pump shaft of the axial flow pump through the axial and radial positioning of the stop portions.

[0009] As a further improvement to the technical solution of the present invention, the first and second turning gear half sets are both provided with bolt mounting holes for use with bolts and nuts; by fastening the bolts and nuts in conjunction with the bolt mounting holes, the first and second turning gear half sets are covered together to form the turning gear cover.

[0010] As a further improvement to the technical solution of the present utility model, the angle between the slide surface and the horizontal direction is an acute angle.

[0011] As a further improvement to the technical solution of the present invention, the first half of the turning gear and the second half of the turning gear are symmetrical structures.

[0012] The utility model has the following beneficial effects:

[0013] Structural and cost advantages

[0014] The turning gear sleeve of this utility model is notably characterized by its rational structure. The layout and connection of its components have been carefully optimized, ensuring that the entire device meets functional requirements while avoiding unnecessary structural complexity. This rational structural design not only reduces production costs but also reduces material waste and processing difficulties during the production process. Furthermore, the installation process is simple and easy, requiring no complex tools or specialized skills, and can be completed by ordinary technicians. This significantly reduces labor costs and installation time, improves overall work efficiency, and makes the product more competitive in the market.

[0015] Easy and efficient installation and alignment

[0016] The structural design of the turning sleeve offers significant advantages during installation. It allows for easy center alignment of the motor and pump during installation. Through unique design elements and positioning mechanisms, it effectively overcomes the difficulty of precise centering in traditional installation methods. This feature significantly shortens installation time, saving significant man-hours compared to traditional methods. Furthermore, this convenient alignment method significantly improves installation quality and reduces issues such as unstable operation and vibration caused by center misalignment.

[0017] Center adjustment is accurate and reliable

[0018] This utility model provides a more convenient, quick, and accurate solution for adjusting the center of the pump and motor. Through its innovative design, the operator can more precisely control the relative position of the pump and motor during the adjustment process, ensuring the consistency of their centers. This precise adjustment capability makes the pump more reliable and stable during operation, effectively reducing the incidence of failures. Furthermore, after assembly, the levelness of the coupling end face automatically aligns with that of the pump foundation, and the center of the coupling also coincides with the rotational center of the pump main shaft. This feature greatly facilitates the center alignment of the motor layer and intermediate transmission components, eliminating the need for complex calibration operations.

[0019] Advantages of adjustable transmission components

[0020] The adjustable centering of the transmission component is another significant benefit of this utility model. This adjustability facilitates alignment of the motor shaft, transmission component shaft, and pump main shaft during installation. Whether during initial installation or subsequent maintenance and adjustments, technicians can easily fine-tune the centering of the transmission component to ensure the coaxiality of the entire drive system. This not only improves the overall performance and reliability of the equipment, but also extends its service life and reduces wear and damage caused by shaft misalignment.
