However, this test bench is only suitable for testing the external characteristics of the self-priming pump self-priming performance. When performing the test and analysis of the internal flow field of the self-priming pump self-priming process, it is necessary to rebuild the test bench, which increases the time cost and economic cost, and reduces the use efficiency.

According to the invention, when external characteristics of a pump such as waterpower performance, self-priming performance and the like are measured, internal flow characteristics such as gas-liquid suction, gas-liquid mixing, gas-liquid separation, gas discharge and water backflow and the like in a self-priming process are observed through the high-speed photography system.
Description
technical field [0001] The invention belongs to the field of fluid machinery experiments, and specifically relates to a collaborative testing system for internal and external characteristics of a pump self-priming process, which is mainly used for simultaneously measuring the external characteristics of pump self-priming performance and the internal characteristics of gas-liquid two-phase flow. Background technique [0002] The self-priming pump is a special centrifugal pump that only needs to be filled with water when it is started for the first time, and the air in the pipeline and the pump body can be discharged every time it is started, and then the water can be delivered normally. It is a key component of light and small irrigation units, and is widely used in rural mobile irrigation, mobile work, frequent start-up and difficult irrigation. In addition to hydraulic performance parameters such as flow rate, head, and efficiency, self-priming pumps also have parameters ...
