Description
Technical field
The utility model relates to engine nozzle douching technique field, specially a kind of aeroengine thrust augmentation pilot jet
Flusher.
Background technique
Reinforcing pilot jet is used on the Afterburner fuel manifold in aero-engine, it has more special structure special
Sign, it is made of spout, swirler, nozzle housing, nozzle housing be two coaxial line cylindrical bodies be formed by connecting, include thick section and
Thin segment does rotary motion rapidly its working principle is that fuel oil enters swirler from tangential hole in swirler, and fuel oil is from spout
After ejection, because of the effect by inertia force and air impact, countless tiny oil droplets are broken into, to obtain good atomization effect
Fruit.The variation of engine required oil mass when working under different rotating speeds is very big, fuel delivery when big revolving speed, generally than small revolving speed when
Fuel delivery it is more than ten to tens times big, in order to guarantee atomization quality, devise fuel oil minimum pressure before test, spout must be tiny
And it is uniform, the phenomenon that blocking can not occur.
Fuel manifold nozzle operation position is in the annular flame tube bottom of combustion chamber, due to the quality of fuel oil and the work of high temperature
To make environment, works long hours and be readily formed carbon distribution, these carbon distributions will cause the blocking of fuel nozzle, after spray nozzle clogging, fuel oil
Atomization quality can decline, as a result will lead to fuel oil and be unable to fully burn, reduce the overall performance of engine, furthermore spray can be changed
Corners of the mouth degree causes linear jet stream, leads to localized hyperthermia, and the turbo blade behind ablation combustion chamber is serious to cause flight thing
Therefore when reinforcing pilot jet is blocked, the method for taking backwash fuel manifold is excluded.
Such as number of patent application is a kind of aeroengine thrust augmentation pilot jet flusher of CN201720914862.4,
Its main contents are as follows: a kind of aeroengine thrust augmentation pilot jet flusher, including be sequentially communicated inlet connector, oil transportation
Hose and flowline connection to subsea, flowline connection to subsea are connected to fixture, and fixture includes swagelok and supports bar, and swagelok is equipped with
Place the groove of nozzle；The inside for supporting bar is equipped with one end connection flowline connection to subsea that bar is supported through the through-hole for supporting bar, out
Oil connection is equipped with limitation and supports the mobile locating part of bar, supports the bar other end and is located in groove, and supports with one end of nozzle
It holds, the other end through-going recess of nozzle, the blocking platform supported with the thick section of nozzle is equipped in groove, through-hole is connected to nozzle.Though
The flusher of the right device when in use, without taking out nozzle from jet pipe, is placed the nozzle into wherein by groove,
The mobile bar that supports can be completed clamping, when taking-up, it is only necessary to which bar will be supported by, which removing locating part, loosens, and nozzle is taken by groove
Out, but the device to the fixation of nozzle be only between tube and pipe it is mutual reinforcing dock so that the flusher
The sealing performance poor flush efficiency lower time for making nozzle during being rinsed to nozzle is longer, and the device
Recycling kerosene that can not be effective and reasonable after being cleaned using kerosene to nozzle, will cause the biggish wasting of resources.
Based on this, the utility model devises a kind of aeroengine thrust augmentation pilot jet flusher, above-mentioned to solve
Problem.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of aeroengine thrust augmentation pilot jet flusher
The device proposed in background technique to the fixation of nozzle be only between tube and pipe it is mutual reinforcing dock so that the flushing
Sealing performance of device during being rinsed to the nozzle poor flush efficiency lower time for making nozzle is longer, and should
Device can not be effective and reasonable after being cleaned using kerosene to nozzle recycling kerosene, will cause asking for the biggish wasting of resources
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of aeroengine thrust augmentation pilot jet
Flusher, including position-limiting tube and connection seal pipe are rinsed, outer wall is provided with external screw thread, the punching on the left of the flushing position-limiting tube
It washes position-limiting tube right end and is communicated with flushing outlet tube, the middle section for rinsing outlet tube is provided with check valve, the flushing outlet tube
The right side right end that is provided with Rose Box, and rinses outlet tube run through the left side wall of Rose Box, consolidate in the middle part of the filtering box cavity
Surely it is connected with filter screen, recovery tube is provided on the right side of the Rose Box, and the right side wall of Rose Box is run through in the left end of recovery tube,
The inner wall of the connection seal pipe is provided with internal screw thread, is connected with rotary joint on the left of the connection seal pipe, the rotation connects
Head left side is connected with oil hose, and the left end of the oil hose is connected with inlet connector, and the flushing limit tube cavity is put
It is equipped with nozzle to be cleaned.
Preferably, the nozzle left end to be cleaned outer diameter, which is equal to, rinses position-limiting tube left end inner diameter, described to clear
It washes nozzle right end outer diameter and is less than flushing position-limiting tube right end inner diameter.
Preferably, the recovery tube right end is connected with extraneous kerosene recycling bins.
Preferably, the inlet connector left end is connected with extraneous flow tester.
Preferably, the recovery tube left end is located at Rose Box intracavity bottom.
Preferably, the connection sealing pipe outer wall is provided with non-slip texture.
Preferably, the flushing outlet tube right end is located at the filtering box cavity upper left corner.
Compared with prior art, the utility model has the beneficial effects that the utility model has to aeroengine thrust augmentation
Pilot jet carries out the function of high-efficiency rinsing, rinses position-limiting tube by setting and makes device in flooding nozzle with good close
