Heater electrode ablation condition monitoring device

Abstract

The invention provides a heater electrode ablation condition monitoring device. The heater electrode ablation condition monitoring device comprises a rotary measuring probe, a movable rod, a probe adjusting control device and a data processing display device; the rotary measuring probe is connected with the probe adjusting control device through the movable rod, the rotary measuring probe is provided with radial telescopic teeth and a high-precision camera, and the radial telescopic teeth can stretch out and draw back in the radius direction of the rotary measuring probe; and the signal output port of the high-precision camera is connected with the data processing display device, and the data processing display device is fixed on the probe adjusting control device. According to the invention, the inner surface of the heater electrode generating ablation is measured and photographed to form the inner diameter size on each ablation section, the ablation amount on each point in the circumferential direction and the actual ablation morphology image, so that the effective monitoring of the ablation condition of the heater electrode is realized.

Description

technical field [0001] The invention relates to the technical field of equipment monitoring, in particular to a heater electrode ablation monitoring device. Background technique [0002] In the aerospace field, an arc heater is used to generate an arc to ablate the model. When the heater is working, the arc formed inside the electrode is also continuously ablated the electrode, and eventually the electrode is burned through, causing water leakage and causing arc extinguishing, thereby interrupting normal operation. The model ablation test not only affects the progress of the test, but also has an adverse effect on the model and the heater itself. [0003] Under the existing conditions, it is generally judged whether the electrode needs to be replaced by visually observing the internal ablation of the electrode. This method not only relies on the experience of a large number of ablation tests, but also cannot accurately judge the timing of electrode replacement. Contents of...

[0003] Under the existing conditions, it is generally judged whether the electrode needs to be replaced by visually observing the internal ablation of the electrode. This method not only relies on the experience of a large number of ablation tests, but also cannot accurately judge the timing of electrode replacement.
