The invention discloses an experimental facility for calculating flow of a major-diameter pipeline through flow of a minor-diameter pipeline and relates to a major-diameter flow measuring experimental facility. The major-diameter flow measuring experimental facility is composed of a water absorption pipe, a water pump, adjusting valves, a main pipeline, branched pipelines and water tanks. The water absorbing pipe (1) absorbs water from an underground water channel, and the absorbed water is output and conveyed to the main pipeline (6), the first branched pipeline (5) and the second branched pipeline (7) through the water pump (2); the first valve (3) and the second valve (4) control flow of water flowing into the first branched pipeline (5) and flow of water flowing into the second branched pipeline (7) respectively. Water flowing out of the main pipeline (6), water flowing out of the first branched pipeline (5) and water flowing out of the second branched pipeline (7) flow into the first water tank (8), the second water tank (9) and the third water tank (10) respectively, the fluid flow of the pipelines are measured through an experiment, the flow relation curve of the major-diameter pipeline and the minor-diameter pipeline under different cross section ratios and different loads is obtained, and the fluid flow of the major-diameter pipeline can be worked out through the flow of the minor-diameter pipeline.
Description
technical field [0001] The invention relates to an experimental device for flow measurement, in particular to an experimental device for calculating the flow rate of a large-diameter pipeline by using the flow rate of a small-diameter pipeline. Background technique [0002] There are many large-diameter fluid pipelines in thermal power plants, for example, the diameter of circulating water pipelines reaches more than 2 meters. Usually, ultrasonic flowmeters are used to measure the flow of large-diameter pipelines. However, ultrasonic flowmeters are not only expensive, but also have large deviations in measurement data when measuring the flow of large-diameter pipelines. However, the requirements for large-diameter flow measurement at home and abroad are still under the relatively rough result requirements, and the operation is often judged by operating experience. This patent is an experimental device for calculating the flow rate of large-diameter pipes by using the flow r...
