Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline performance detection, and particularly relates to a multi-branch pipeline flow uniformity detection device. Background Technique

[0002] The detection of multi-branch pipeline flow uniformity involves multiple aspects such as chemical engineering, water conservancy, and industrial production, which is mainly due to the high demand for fluid distribution uniformity in engineering applications. In the chemical engineering field, multi-branch pipelines are widely used in equipment such as radial catalytic reaction distributors and plate heat exchangers. These devices need to ensure uniform fluid distribution in multiple branch pipelines to guarantee the efficiency of reaction or heat exchange. In the drip irrigation project of water conservancy projects, pipeline design needs to ensure that water can be evenly distributed to each irrigation point to improve irrigation efficiency and reduce water resource waste. In the process of industrial production, pipelines are important facilities for carrying fluid transmission. The flow uniformity of multi-branch pipelines is crucial for ensuring the stability of the production process and product quality.

[0003] In a multi-branch pipeline system, due to factors such as the parallel form of pipelines and the resistance loss of branch pipes, the flow distribution of each branch pipe is often uneven. This uneven flow distribution will affect the overall performance and efficiency of the system. With the development of industrial production capacity, the demand for the detection of multi-branch pipeline flow uniformity is increasing day by day. The traditional method of solving the problem of uneven flow distribution in multi-branch pipelines usually highly relies on manual participation and requires a large amount of human input. This method is not only complex and inefficient in operation, but also has low measurement and analysis accuracy. Therefore, there is an urgent need to develop an automatic detection device to efficiently and accurately detect the flow conditions of each branch pipe and quickly analyze the statistical characteristics of the flow of each branch, so as to improve the product performance detection efficiency of pipeline production enterprises.

[0028] The following Figures 1 to 4 will further describe the present utility model in detail.

[0029] A multi-branch pipeline flow uniformity detection device includes an installation platform 1, a pipeline installation box 2, a liquid guide hose 3, a column 4, a fixed beam 5, a pipe clamp 6, a movable beam 7, an electric push rod 8, an electric push rod support 9, a linear bearing 10, a guide rail 11, a liquid collection tank 12, a measuring cup 13, a cup holder 14, a force sensor 15, and a drain pipe 16.

[0030] Specifically, the multi-branch pipeline flow uniformity detection mainly includes five steps, which are, in sequence: pipeline installation and connection, detection preparation, formal detection, stop detection, and data analysis.

[0031] By adopting the above technical solution, the high-efficiency and high-precision detection of the multi-branch pipeline flow uniformity can be completed.

[0032] Specifically, during the pipeline installation and connection process, according to Figure 1As shown, a multi-branch pipeline flow uniformity detection device is built. The multi-branch pipeline is installed in the pipeline installation box 2, and each branch is connected to the corresponding liquid guiding hose 3. The liquid guiding hose 3 passes through the pipeline installation box 2, the pipe clamp 6, and the movable beam 7 in sequence.

[0033] By adopting the above technical solution, the connection between the multi-branch pipeline to be detected and the detection device can be completed.

[0034] Specifically, during the detection preparation process, the electric push rod 8 controls the movable beam 7 to align the liquid guiding hose 3 with the liquid collecting tank 12. All force sensors 15 collect and clear the data, and all drain pipes 16 are closed.

[0035] By adopting the above technical solution, the preparation work before the flow uniformity detection can be completed, ensuring that the initial state of the detection device is intact before each detection.

[0036] Specifically, during the formal detection process, the pipeline to be detected is supplied with liquid. After the liquid in the liquid guiding hose 3 flows stably, the electric push rod 8 controls the movable beam 7 to align with the measuring cup 13. After timing for one minute, the electric push rod 8 controls the movable beam 7 to align with the liquid collecting tank 12.

[0037] By adopting the above technical solution, the liquid volume flowing into the measuring cup 13 in all branches can be synchronously controlled, ensuring the consistency of the measurement.

[0038] Specifically, during the process of stopping the detection, the liquid supply to the pipeline is stopped. The force sensor 15 records the liquid weight in each measuring cup 13, and the drain pipe 16 is opened to drain the liquid in the measuring cup 13.

[0039] By adopting the above technical solution, the liquid weight flowing through all branches per minute can be measured.

[0040] Specifically, during the data analysis process, the results measured by all force sensors are transmitted to the data acquisition and analysis system, and then combined with the liquid density, the statistical characteristics such as the average value and standard deviation of the volume flow rate of each branch of the pipeline are quickly analyzed, and the serial numbers of the branches with relatively large flow deviations are given at the same time.

[0041] By adopting the above technical solution, the liquid volume flowing through the multi-branch pipeline per minute can be quickly calculated, and the flow uniformity of the multi-branch pipeline can be obtained.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
