Technical field
The present invention's design relates to aero-engine cyclone spray test technology, is specifically related to a kind of frock clamp for aero-engine cyclone spray test.
Background technology
Fanjet operates, and the high temperature and high pressure gas produced by the burning of combustion chamber intermediate fuel oil produces power drive from the ejection of afterbody jet pipe, thus provides power for aircraft.Therefore, can the thrust of quality to engine that produce high temperature and high pressure gas and high temperature and high pressure gas have a direct impact.Produce the high temperature and high pressure gas met the demands, need fuel oil to carry out Thorough combustion in a combustion chamber.Research proves, fuel oil combustion efficiency under spray pattern is best.Cyclone is device fuel oil being become spray pattern from liquid state.The air of the counterclockwise High Rotation Speed that the gas mixture of the clockwise High Rotation Speed that cyclone is produced by top and bottom produce, at cyclone outlet, place clashes into mutually, thus makes fuel oil reach spray pattern.Whether cyclone can change qualified spray pattern completely into by fuel oil directly affects the burning of fuel oil in combustion chamber, causes high temperature and high pressure gas quality to be affected, thus affects the performance of engine.
In order to improve the reliability of engine, needing to carry out atomization simulated experiment before cyclone installation, checking the atomizing effect of cyclone.Current manufacturing enterprise replaces fuel oil to simulate the work of cyclone by simple frock fixture with clear water, but in this frock clamp, the clear water of fuel oil is replaced only to enter cyclone by smooth-bore tip, the pilot jet of cyclone is shut, namely simulated test is not carried out by the real duty in combustion chamber, and frock clamp sealing property is bad, there is gas leakage oil leakage phenomenon, cyclone is also acerous to positioner, the position causing smooth-bore tip to insert working connection oil-in in cyclone cannot be fixed, there will be and pour in down a chimney, test current cannot enter cyclone completely and produce rotation.Therefore analog result can not represent the real work state of cyclone, can not detect entirely truely get rid of the bad cyclone of atomizing effect.And engine loaded onto by the bad cyclone of atomizing effect, can restrict the output of engine power, and then affect the performance of aircraft.
In order to improve the performance of engine, improve the atomization qualification rate of cyclone, be badly in need of in production practices providing the frock clamp can tested cyclone spray pattern, to simulate the real work state of cyclone in engine combustion indoor, get rid of the underproof cyclone of atomizing effect, ensure that engine reliable is run.
Summary of the invention
