The invention discloses a self-circulation open channel experimental device with the teaching effect flow digital display function. The self-circulation open channel experimental device comprises a self-circulation open channel experiment instrument, a differential pressure high-end liquid gas conversion cylinder, a differential pressure low-end liquid gas conversion cylinder, a differential pressure sensor and a microcomputer digital display instrument. The self-circulation open channel experiment instrument comprises a water delivery pipeline, and one segment of the water delivery pipeline is a differential pressure type flow signal generator used for generating differential pressure signals. The differential pressure high-end liquid gas conversion cylinder and the differential pressure low-end liquid gas conversion cylinder are connected with the differential pressure type flow signal generator. The differential pressure sensor is connected with the differential pressure high-end liquid gas conversion cylinder and the differential pressure low-end liquid gas conversion cylinder in a sealed mode and used for detecting the differential pressure between compressed air in the differential pressure high-end liquid gas conversion cylinder and compressed air in the differential pressure low-end liquid gas conversion cylinder. The microcomputer digital display instrument is connected with the differential pressure sensor and used for converting the differential pressure signals detected by the differential pressure sensor into flow. According to the self-circulation open channel experimental device with the teaching effect flow digital display function, in a preferred technical scheme, zero setting can also be performed in real time in the normal flow measurement experimental process, and the self-circulation open channel experimental device is a small-flow high-precision flow instrument used for experiments.
Description
technical field [0001] The invention relates to the field of experimental measurement, in particular to a self-circulating open channel experimental device with teaching effect flow digital display. Background technique [0002] Water flow movement is a very complex natural phenomenon. The existence of various forces and the laws of their development have not been well grasped so far. The hydraulic model test is modeled on the original body and scaled down according to similar principles. Form a model, and carry out experimental research according to the main forces it receives. In the hydraulic model test, in order to cooperate with the overall hub layout or to study some binary water flow problems, it is necessary to build an open channel experimental tank, with the help of the open channel experimental tank to observe the flow state of the water, and to describe or record various water flow phenomena during the experiment. [0003] Therefore, as an experimental platform,...
