Description

technical field [0001] The invention relates to the technical field of aging of ignition electric nozzles, in particular to a timing aging device for ignition electric nozzles. Background technique [0002] Aeroengine ignition nozzles are used to generate high-energy electric sparks under the excitation of high-voltage electric pulses to ignite the oil-air mixture in the combustion chamber. The ignition nozzle mainly breaks through the air through the high-voltage electric energy generated by the positive and negative electrodes to generate electric sparks. However, in the actual production process, the electrode breakdown channel of the newly produced ignition nozzle has not been formed and fixed, and spark instability will occur during use. Case. Therefore, the newly produced ignition nozzle must undergo aging (that is, the ignition nozzle works according to a certain working system for a period of time to make its spark stable) so that its breakdown channel is fixed and ...

AI Technical Summary

Problems solved by technology

The main problems of this aging method are as follows: First, it is limited by the fixed working system of the ignition device, and it is necessary to stop to rest after working for about 30 seconds, and the rest time after 3 times of work is more than half an hour, so the aging efficiency is low; Second, using the ignition device for sophisticated work will consume the service life of the ignition device, and the economy is poor; third, the switching between sophisticated work and rest states needs to be operated manually, and the degree of automation is low, which is not conducive to personnel operation. It is not conducive to accurate and timely switching of working status
