Description

Technical Field

[0001] The invention relates to the technical field of horizontal axial flow pump installation, and in particular to an installation method of a horizontal axial flow pump with an S-type flow channel based on Revit simulation. Background Art

[0002] In recent years, in order to meet the requirements of flood control, drainage, irrigation, etc., a large number of drainage sluice stations and drainage pumping stations have been built in my country's coastal areas. Among them, horizontal axial flow pumps are widely used because of their high operating efficiency (can be increased by 5% to 7%), relatively stable water flow, reduced excavation depth and easy installation and maintenance.

[0003] The S-type flow channel horizontal axial flow pump has a large change in appearance and structure compared to conventional horizontal axial flow pumps, and contains a large number of non-standard components, so its installation nodes are complex and difficult. In the traditional installation process, the installation workers refer to the drawings and temporarily decide the assembly and hoisting methods based on previous operating experience and the hoisting conditions of the on-site pump components. This is subjective and arbitrary, and measures are taken to deal with problems after they are encountered, which can easily keep the installation work in a passive state of uncertainty. In addition, due to the lack of intuitive understanding of the installation sequence and installation plan of the pump structure components, the installation is time-consuming and laborious, and even causes operational errors and rework, which has an adverse impact on the construction progress and project costs. Summary of the invention

[0021] Furthermore, the assembly process specifically includes the following steps:

[0022] S51, assigning a three-dimensional model of a structural component of the S-type flow channel horizontal axial flow pump in stages, so that each installation stage includes one or more components in the structural model of the S-type flow channel horizontal axial flow pump;

[0023] S52, according to the installation plan, setting a specific construction plan for the components in each installation stage, and establishing a model corresponding to the installation stage;

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] like Figure 1As shown, an embodiment of the present invention provides an S-type flow channel horizontal axial flow pump installation method based on Revit simulation, which is used in a pump station project. The gate station consists of a single-hole regulating gate (steel dam gate) with a net width of 10m and two 1500ZWB5.65-2.7 flat S-type horizontal axial flow pumps (with a total drainage flow of 10.0m3 / s). Two 1500ZWB5.65-2.7 one-way horizontal axial flow pumps are installed in the new pump room, and the motor is 280kW / unit. The water pump consists of an impeller component, a water guide bearing component, a thrust bearing component, a main shaft component, a pump body component, a sealing component, etc. The two water pumps share one pump room, and the bottom plate of the pump room is 1.50 to 1.90m thick.

[0034] The installation method includes the following steps:

[0035] S1. Analyze and optimize 2D CAD construction drawings;

[0036] Specifically, organize BIM personnel and relevant technical personnel to conduct analysis and research on construction drawings to grasp project information and project characteristics.

[0037] S2. Create the main structure model of the civil engineering to which the S-type flow channel horizontal axial flow pump is attached;

[0038] Specifically, under the premise of complying with relevant modeling specifications and standards, the BIM software Autodesk Revit was selected to create the main structure model of the civil engineering to which the S-type flow channel horizontal axial flow pump is attached.

[0039] This step can avoid the impact of environmental foundation on subsequent construction by simulating the main civil structure, which is conducive to the subsequent installation of the S-type flow channel horizontal axial flow pump.

[0040] S3. Create a structural component model of a horizontal axial flow pump with an S-shaped flow channel;

[0041] Specifically, a three-dimensional model of the S-type flow channel horizontal axial flow pump structural component is established in accordance with the modeling specifications. The three-dimensional model of the component includes the component's material, specification, size, elevation, angle, node method, connection holes and connectors, detailed construction information and operation and maintenance information.

[0042] This step effectively utilizes the three-dimensional visualization tips of related BIM technology to display the overall three-dimensional shape of the S-type flow channel horizontal axial flow pump to be assembled and the spatial geometric relationship between components, solving the problem that it cannot be expressed intuitively in a two-dimensional state.

[0043] S4. Integrate the civil engineering main structure model with the S-type flow channel horizontal axial flow pump structural component model;

[0044] In addition, the two sets of models also include the following steps after integration:

[0045] S41. Conduct 3D roaming inspection on the integrated model to determine the precise connection between the S-shaped flow channel horizontal axial flow pump structure and the main civil engineering structure;

[0046] S42, detecting whether the integrated model has problems in terms of spatial collision and position deviation, and highlighting the parts with problems;

[0047] S43. Optimize the dimensions and elevations, check the highlighted parts that have been identified as errors, and communicate with the design unit, construction unit, supervision unit, and manufacturer representatives to promptly adjust the dimensions and elevations of the structural components of the S-type flow channel horizontal axial flow pump.

[0048] This step intuitively shows whether there are collisions, conflicts, dimensional deviations, etc. between model components, so that problems in the drawings can be discovered in a timely manner, unnecessary rework can be avoided, and construction efficiency can be improved.

[0049] S5. Decompose and split the integrated model, perform simulation assembly, and select the optimal installation plan;

[0050] Specifically, the three-dimensional model of the structural component of the S-type flow channel horizontal axial flow pump is split and decomposed according to the corresponding connection nodes, the information of each structural component is extracted and numbered and sorted in sequence, and the BIM software Autodesk Revit is used to simulate the assembly process; wherein the assembly process specifically includes the following steps:

[0051] S51, assigning a three-dimensional model of a structural component of the S-type flow channel horizontal axial flow pump in stages, so that each installation stage includes one or more components in the structural model of the S-type flow channel horizontal axial flow pump;

[0052] S52, according to the installation plan, setting a specific construction plan for the components in each installation stage, and establishing a model corresponding to the installation stage;

[0053] S53. Perform scheme demonstration and comparison based on the different disassembly and assembly step diagrams formed by each installation scheme to obtain the optimal installation scheme and component installation sequence.

[0054] In this step, the three-dimensional model of the S-type flow channel horizontal axial flow pump structural components is constructed using Revit software. Each structural component is disassembled in an orderly manner. By assigning phased model settings to different installation schemes, a simple and easy-to-understand disassembly and assembly step diagram is formed, so as to optimize the scheme and guide the installation construction, speed up the installation progress, and improve the installation quality and assembly efficiency.

[0055] S6. Use the 3D model of the S-type flow channel horizontal axial flow pump structural components to conduct 3D visualization technology briefings to management personnel and on-site installation workers, and form on-site construction operation documents;

[0056] This step helps construction personnel gain an intuitive understanding of the installation sequence and installation plan of the S-channel horizontal axial flow pump structural components, enhances their understanding of construction precautions, and facilitates subsequent installation operations.

[0057] S7. Install and construct the S-type flow channel horizontal axial flow pump according to the construction work documents.

[0058] In summary, compared with the traditional water pump installation and construction, the S-type flow channel horizontal axial flow pump installation method based on Revit simulation has the characteristics of visualization and simulation. The use of Revit software to build the model reduces the rework caused by drawing problems and human errors, reduces material waste and pollution caused by the rework process. And through the disassembly and assembly step diagram to optimize the scheme, it improves work efficiency, shortens the construction period, reduces time and labor costs, and has good social and economic benefits.

[0059] The present invention is not limited to the above-mentioned specific implementation modes. For ordinary technicians in this field, various changes made based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
