Multi-functional fluid mechanics experimental apparatus

Abstract

The invention relates to a multi-functional fluid mechanics experimental apparatus. The multi-functional fluid mechanics experimental apparatus includes a water tank connected with a water incoming pipe with an electromagnetic valve, a controller and a touch screen; a side wall of the water tank is provided with two pressure transmitters with different heights; the bottom of the water tank is connected with a first water suction pump and a second water suction pump respectively through pipelines; the first water suction pump is connected with a first horizontal pipe with an electromagnetic valve through a pipeline; the first horizontal pipe is connected with a second horizontal pipe at a lower position through a vertical pipe; the first horizontal pipe and the second horizontal pipe are both provided with a flow meter and a pressure transmitter; the second water suction pump is connected with a horizontal Renault pipe through a pipeline with an electromagnetic valve and a flow meter; the inlet end of the Renault pipe is connected with an ink box at a higher position through a pipeline with an electromagnetic valve; the first water suction pump, the second water suction pump, all the electromagnetic valves, the pressure transmitters and the flow meters are respectively connected with the controller; and the controller is connected with the touch screen. With the multi-functional fluid mechanics experimental apparatus adopted, a plurality of fluid mechanics experiments can be completed. The multi-functional fluid mechanics experimental apparatus has the advantages of high measuring precision, fully-automatic operation and high experiment efficiency.

Description

technical field [0001] The invention belongs to the field of fluid mechanics experiment teaching equipment, and in particular relates to a multifunctional fluid mechanics experiment device. Background technique [0002] At present, the traditional fluid mechanics experimental teaching equipment has the following problems: 1) The function is single, and one experimental device can only complete one fluid mechanics experiment, and each experiment requires a lot of preparation work, which is inefficient; 2) During the experiment, the pressure Traditional pressure tubes and Pitot tubes are mostly used for the measurement of flow rate and flow rate, so the reading time of measured data is long and the accuracy is low; 3) During the experiment, all test data need to be handwritten and recorded in time, and then calculated after the operation is completed In addition, various valves need to be opened and closed manually or the opening degree adjusted manually during the experiment,...
