The invention relates to the technical field of liquid discharge, and discloses an experimental device for liquid discharge characteristics, including a voltage transformer, an upper electrode, a lower electrode, an experimental box, a liquid injection tank, a vacuum machine, a voltage detection device and a current detection device; The electrode and the lower electrode are set in the inner cavity of the experimental box, the voltage transformer is connected to the upper electrode, the lower electrode is the ground electrode, the voltage detection device is connected between the upper electrode and the lower electrode, and the current detection device is connected to the lower electrode ; The liquid injection tank is connected with the experiment box body, and the vacuum machine is connected with the liquid injection tank. The discharge experiment is carried out in the liquid to be tested between the upper electrode and the lower electrode, and the discharge characteristics of the liquid to be tested are obtained through the voltage detection device and the current detection device. During the discharge characteristic test, the liquid injection tank can be pumped by a vacuum machine And gas, quickly change the hydrostatic pressure characteristics of the liquid, and realize the experimental research on the discharge characteristics of the liquid under different hydrostatic pressure levels.

Description

technical field [0001] The invention relates to the technical field of liquid discharge, in particular to an experimental device for liquid discharge characteristics. Background technique [0002] The electrohydraulic effect is a general term for physical effects such as heat, light, force, and sound that are accompanied by high-speed energy conversion during high-voltage, high-current pulse discharge in liquid media. The hydroelectric effect is widely used in industry, such as mechanical processing and manufacturing, electric pulse cleaning, in vitro gravel, and making underwater sonar equipment. Because the use of discharge technology in liquid (such as water) to generate hydroelectric effect has the advantages of environmental friendliness, high efficiency, and low cost, the research and application of discharge characteristics in water have attracted more and more attention. [0003] The discharge process in liquid is a complex physical and chemical process. For the ex...
