Technical field
Present invention design is related to aero-engine cyclone spray test technology, and in particular to a kind of to be used for aero-engine
The frock clamp of cyclone spray test.
Background technology
Fanjet operates, and the high temperature and high pressure gas for producing that burn by combustor intermediate fuel oil spray from afterbody jet pipe and produce
Power drive, so as to provide power for aircraft.Accordingly, it is capable to the no quality of high temperature and high pressure gas and high temperature and high pressure gas that produces is to sending out
The thrust of motivation has a direct impact.Produce and meet the high temperature and high pressure gas for requiring, need fuel oil to carry out in a combustion chamber fully
Burning.Research has shown that fuel oil combustion efficiency under spray pattern is best.Cyclone is that fuel oil is transformed into spray pattern from liquid
Device.The high speed counterclockwise that the gas mixture of rotation at a high speed clockwise and bottom that cyclone is produced by top is produced
The air of rotation, mutually clashes at cyclone outlet, so that fuel oil reaches spray pattern.Whether cyclone can be by fuel oil
Be completely transformed into qualified spray pattern and fuel oil directly affects in the indoor burning of burning, cause high temperature and high pressure gas quality to be subject to
Affect, so as to affect the performance of electromotor.
In order to improve the reliability of electromotor, need atomization simulation experiment to be carried out before cyclone installation, check cyclone
Atomizing effect.Manufacturing enterprise is all to replace fuel oil to simulate the work of cyclone by simple frock fixture and with clear water at present
Make, but in the frock clamp, replace the clear water of fuel oil only cyclone, the pilot jet envelope of cyclone to be entered by smooth-bore tip
Extremely, i.e., do not press the real working condition of combustor and be simulated test, and frock clamp sealing property is bad, there is gas leakage oil leak
Phenomenon, cyclone cause the position of working connection oil-in in smooth-bore tip insertion cyclone consolidate also without angular positioner
Fixed, it may appear that to pour in down a chimney, test current cannot produce rotation completely into cyclone.Therefore analog result can not represent cyclone
Real work state, it is impossible to be correctly detected completely and exclude the bad cyclone of atomizing effect.And the bad eddy flow of atomizing effect
Device loads onto electromotor, can restrict the output of engine power, and then affect the performance of aircraft.
In order to improve the performance of electromotor, the atomization qualification rate of cyclone is improved, being badly in need of offer in production practices can be right
The frock clamp tested by cyclone spray pattern, to simulate real work state of the cyclone in engine combustion room,
Exclude the underproof cyclone of atomizing effect, it is ensured that engine reliable is run.
The content of the invention
For the deficiencies in the prior art and present situation, the purpose of the present invention aims to provide a kind of for aero-engine cyclone

Pressure-bearing joint is arranged on cyclone auxiliary fuel entrance, and the fixed structure on the support is solid by cyclone by pressure-bearing joint
Dingan County is mounted on base；Air intake adapter is designed on the end cap.
In the above-mentioned technical proposal of the present invention, the cylinder and end cap decision design into by the external screw thread on cylinder and
Female thread on end cap is fixedly connected；The cylinder and base decision design into being fixedly connected by clamping thread bush, the card
Connect thread bush be designed with the interior snap ring that matches with the outer snap ring on base and with cylinder lower end on external screw thread match in
Screw thread.Its two ends of the cylinder are machined with the cylinder external diameter of the cylinder external diameter of male thread portion more preferably greater than interlude, in order to
The processing of screw thread.
In the above-mentioned technical proposal of the present invention, the support decision design is into the "+" type plane being installed with cylinder
Frame；The fixed structure be contemplated that be designed to by be arranged on by screw thread pair "+" type planar bracket center top pressure pin and
Positioning pin column is constituted, and the lower end of the top pressure pin acts on the pressure-bearing joint upper end installed in cyclone auxiliary fuel entrance
Face, the positioning pin column lower end are engaged with the location structure on pressure-bearing joint；Positioning pin column preferably two, is symmetricly set on
On the "+" type planar bracket of top pressure pin both sides.
Compared with prior art, the present invention has following very prominent Advantageous Effects：
1st, the present invention carries out spray test to cyclone with fuel oil, carries out atomization examination to cyclone with clear water before replacement
Test, and fuel oil enters cyclone with auxiliary fuel oil-feed adapter exit from the direct current fuel inlet of cyclone, i.e., starting
When machine operates, fuel oil enters the fluidised form entrance of cyclone, and true simulation cyclone is in the indoor working condition of burning, detection rotation
The atomizing effect of stream device, can exclude the underproof cyclone of atomization exactly, improve the qualification rate of engine assembly cyclone, protect
Card atomizing effect of the fuel oil in engine combustion room, improves the combustion rate of fuel oil, it is ensured that engine power output performance.
2nd, spray test is carried out using the frock clamp of the present invention to aero-engine cyclone, rotary clamping thread bush is
