Abstract

The invention discloses a microwave tube experiment device. A microwave tube is arranged on an optical platform and a support, and comprises an experiment section, a low voltage section, a mediate voltage section and a high voltage section which are arranged in sequence; microwave tube end caps are arranged at two ends of the microwave tube; a pressure sensor, a mixed gas chamber and a tap are arranged on the low voltage section; a molecular pump extraction section and a capsule device are arranged on the mediate voltage section; the experiment section comprises an experiment section tube body, and observing windows are symmetrically formed in front and rear walls of the experiment section tube body; the pressure sensor comprises a PCB pressure sensor, a pressure sensor gland, a first connecting part, a second connecting part and a copper ring; a seal ring is arranged on the plane, matched with the second connecting part, of the first connecting part; two flanges for connecting are arranged on the capsule device, and a capsule holder is arranged between the two flanges. The microwave tube experiment device is smart in idea, compact in structure, convenient and quick to assemble and safe and stable to use, and is convenient for observing experiment effects.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a shock tube experimental device. Background technique [0002] In the current study, the chemical shock tube can provide a constant temperature and pressure reaction environment, which is an ideal reactor for fuel oxidation research. During the experiment, the driving gas (helium, nitrogen, etc.) is filled in the high-pressure section first, and the experimental combustible gas is filled in the low-pressure section. After reaching a certain pressure difference, the diaphragm ruptures to generate a shock wave, and the shock wave reaches the pressure sensor in the low-pressure section. The optical window is reflected by the end face to form a reflected shock wave, and the reflected area can provide a high temperature and high pressure experimental environment. [0003] In the shock tube commonly used in the prior art, only three observation holes with a diameter of...
