District.It should be noted that electromotor can be connected with vacuum pump if desired, form ultralow nip.
Step 106, is filled to propellant in the combustor of electromotor.
Further, in one embodiment, also include being discharged to outside electromotor the gas in combustor by air channel
Portion, wherein, arranges an air channel in combustor end.
The propellant packing method of a kind of micro combustions room that the present invention provides, starts by being positioned over by tiny engine
Machine is placed in chamber, and jet pipe is upwards placed；It is configured with both sides, bottom on the top of electromotor, forms pressure reduction；
Propellant is filled in the combustor of electromotor.Said method can solve the problem that in prior art, padding is loaded down with trivial details, and difficulty is big
Problem, and have by propellant load convenience and ease for use.
Based on same inventive concept, additionally provide the propellant filling device of a kind of micro combustions room, due to this device solution
Certainly the principle of problem is similar to the propellant packing method of aforementioned a kind of micro combustions room, and therefore, the enforcement of this device can be by
Concrete steps according to preceding method realize, and repeat no more in place of repetition.
As in figure 2 it is shown, be the structural representation of the propellant filling device of a kind of micro combustions room in an embodiment.
The propellant filling device 10 of this micro combustions room includes: structure arranges module 200, pressure reduction arranges module 400 and filling module
600。
Wherein, structure arranges module 200 and places in chamber for tiny engine is positioned over electromotor, and tail is sprayed
Pipe is upwards placed；Pressure reduction arranges module 400 for being configured with both sides, bottom on the top of described electromotor, forms pressure reduction；
Filling module 600 is for being filled to propellant in the combustor of described electromotor.
In the present embodiment, pressure reduction arranges module 400 and includes: higher-pressure region arranges module 410 (not shown) for sending out
Motivation top is connected with air compressor by modular, pneumatically powered joint, forms higher-pressure region；And low-pressure area arranges module 420 (figure
Not shown in) for being connected with air electromotor bottom, form low-pressure area.It should be noted that if desired can be by electromotor
It is connected with vacuum pump, forms ultralow nip.
In addition it is also necessary to explanation, in the propellant packing method of the micro combustions room that the present embodiment proposes and device
Higher-pressure region module 410 is set, structure arranges module 200 and low-pressure area arranges module 420 and can also carry out the most successively
Install and arrange.Thus, improve the motility that device is suitable for.
Additionally, the propellant filling device 10 of a kind of micro combustions room of this embodiment proposition also includes: gas discharges mould
Block 700 (not shown) is for being discharged to external engine by the gas in combustor by air channel, wherein, at combustor end
Portion arranges an air channel.
The propellant filling device of a kind of micro combustions room in order to be more fully understood that and apply the present embodiment to propose, is carried out
The example below.It should be noted that this example is only in order to explain the present invention, it is not intended to limit the present invention.
Specifically, as it is shown on figure 3, during filling propellant, be placed in by electromotor in 2 chambers, jet pipe is upwards placed, and will push away
Enter agent to be previously positioned at jet pipe.Additionally, portion is connected with air compressor by modular, pneumatically powered joint on the engine, formed
Higher-pressure region；Electromotor bottom is connected with air, forms low-pressure area.So, form great pressure reduction in electromotor both sides, i.e. up to
More than 5 atmospheric pressure, thus propellant is loaded in engine chamber.
Further, in engine chamber end, there is an air channel, as shown in Figure 4, can be by the gas in combustor
Body discharges electromotor by air channel, it is to avoid gas is piled up in a combustion chamber.Need during owing to using to be formed in electromotor both sides
High Pressure Difference, therefore the air-tightness of device has vital impact for the filling effect of propellant.
It should be noted that overall structure is divided into inside and outside two-layer, for cylinder.Internal layer is the core of propellant filling
Point, outer layer is the auxiliary component that air-tightness strengthens, can the according to circumstances selectivity use when reality is loaded.Pass through between ectonexine
Silica gel piece thick for 0.2mm forms interference fit, it is ensured that air-tightness.Meanwhile, outer layer is attached by M4 plain bolt, passes through spiral shell
Stricture of vagina pretightning force applies assembling internal force to part at axis direction, equally significantly improves device air-tightness.In layer structure,
Also have a closely spaced parietal tooth structure, the air-tightness improving device is also had certain effect.Lining component is divided into upper, middle and lower three
Layer, i.e. ground floor is attached by the modular, pneumatically powered joint of G1/8 with air compressor, forms higher-pressure region；The second layer is used for placing
Electromotor, is carried out the fixing of electromotor, and has a little interlayer bottom the second layer, be fixed with agent structure by screw,
It is used for doing supporter when electromotor is placed；Third layer, in addition to forming low-pressure area, has also reserved the gas of a same specification
Dynamic joint, can be connected with vacuum pump if desired, improves both sides pressure further, improves propellant filling effect.Additionally, adjacent two
It is attached by M36*1.5 Standard fine thread between Ceng, adds one layer of 0.3mm silica gel piece simultaneously between two-layer and carry further
High-air-tightness also prevented location.
The processing of the propellant filling device of the micro combustions room that the present embodiment proposes uses machining mode to add
Work.During filling, air compressor used is DA5003 compressor, back pressure 0.7Mpa, pressing time 5min.Thus, it is possible to
Making propellant filling comparatively dense, filling effect is satisfied.
The propellant filling device of a kind of micro combustions room that the present invention provides, arranges module 200 by miniature by structure
Electromotor is positioned over electromotor and places in chamber, and jet pipe is upwards placed；Arrange module 400 by pressure reduction again starting
The top of machine is configured with both sides, bottom, forms pressure reduction；Eventually through filling module 600, propellant is filled to electromotor
In combustor.Said apparatus can solve the problem that in prior art, padding is loaded down with trivial details, the problem that difficulty is big, and has propellant dress
The convenience filled out and ease for use.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
