Open, the design work of the program such as spraying frequency setting, the setting of spraying number of times, tempering protection；
The continuous spraying process of order：During detonation flame spraying is carried out, the position of Burners Positions and vertical operation platform exists
Position is had been adjusted between formal spraying；Oxygen, acetylene, powder feeding nitrogen and firing action are that order is continuous；Igniter
The break-make of break-make and powder feeding nitrogen magnetic valve is by continuous trigger according to certain order；Formal spraying starts, oxygen, acetylene electricity
Magnet valve is opened, and the opening action is until actual spraying number of times >=setting spraying number of times, i.e. spraying process terminates；Ignition process be by
Setpoint frequency exports ignition signal, and igniter produces high-tension electricity, by spark ignitor blast indoor gas, until whole spray
Painting process terminates；Powder feeding nitrogen magnetic valve switchs powder feeding nitrogen magnetic valve according to setpoint frequency, by blast powder feeding explosion chamber
Blast is produced with other gas mixings, until formal spraying process terminates；
Spray frequency programs design：The frequency of detonation flame spraying is very important parameter in spraying coating process, directly affects spraying zero
The performance indications such as hardness, the thickness of part；According to the different non-selected corresponding spraying frequencies of spray coating powder, in general, detonation frequency
From 2-10 times/second；The frequency of spraying is substantially exactly the frequency of igniting, and gas is just detonated one in every fire-fighting rifle
It is secondary；So control spraying frequency namely controls the frequency of igniting output (Q101.03) set；Every time before spraying, operating personnel
Corresponding frequency setting value is inputted according to spraying coating process requirement on the touchscreen, this setting value can be kept, until again next time
Input, such design simplifies operating procedure, improves operating efficiency；
The cycle time for controlling each ignition cycle is to spray the key that frequency is realized, i.e., every the output of a cycle time once
The high level of ignition signal；The frequency of detonation flame spraying process stipulation is f=2-10 times/second, and spark rate is not allowed more than typically
This scope；
After operating personnel set detonation frequency f, set-point data is stored in DM300, f=N spray times cycle T=1/N seconds,
T processing datas are stored in DM310, and the l0ms delays in PLC programming softwares connect timer TIM0001 control igniting and continue week
Phase is, it is necessary to ensure at interval of TIM0002 setting igniting cycle T control signals；The subprogram is spraying set of frequency program, defeated
Go out signal Q101.03 and be connected to igniter as trigger signal；
After system cut-off, the spray parameters set spray the information such as number of times, spraying frequency, preset pressure and preset flow,
It can realize and automatically save, what such as next operation was carried out is same process, avoids to repeat setting；Spray number of times and
The data message of spraying frequency is respectively stored in DM170 and DM180, and the data information memory such as flow and pressure is in DM10-
In DM80；
Spray number of times programming：There is this to spray number of times and default spraying two data frames of number of times on the touchscreen, wherein in advance
If spraying number of times needs operating personnel to be preset before formally starting to spray.
2. according to the detonation flame spraying apparatus control method of the aero-engine described in claim 1, it is characterised in that：This spraying
The function of number of times and default spraying number of times is as follows：
This spraying number of times be complete once to spray spray during automatic cycle actually occur number of times, its data storage exists
In DM200, the numerical value auto zero after the completion of a coating cycles；By checking this spraying number of times, operating personnel can be real
When the progress situation that completes of monitoring spraying task；
Default spraying number of times is the demand numerical value of spraying coating process number of times；Operating personnel pass through the default spraying time of touch panel input
Number is into memory DM170；Spray after the completion of number of times setting, operating personnel are after automatic spray procedure is started by preset times
The individual circulatory system stops spray coating operations；
To realize that spray gun is sprayed according to numerical value in spraying number of times DM190, the numerical value before automatically beginning to spraying in DM190 is
0, igniter completes once to light a fire, and is considered spraying operation of completion, is completed to spray the accumulative of number of times with accumulator, when automatic
At the end of spraying, current spraying number of times is reset；
Automatic cycle programming：Coating cycles are identical with ignition cycle, and ignition times can be equal depending on doing coating cycles number of times,
Coating cycles are limited by default spraying number of times, and when reaching spraying number of times predetermined value, coating cycles are completed；Spray parameters are set
After fixed, automatic spraying starts, whenever completing once to spray, and counter is accumulative once to spray number of times, with current spraying number of times
The numerical value of numerical value and preset times DM170 in DM190 is compared, and current spraying number of times numerical value is more than or equal to preset times number
During value, an automatic cycle spraying process is just completed.
3. according to the detonation flame spraying apparatus control method of the aero-engine described in claim 1, it is characterised in that：Enter powder also real
Existing circulate operation, as ignition cycle design method, it is identical with ignition cycle principle to enter powder circulation, to make powder in explosion chamber
In be sufficiently mixed after just lighted a fire, slightly shorter than ignition interval is asked when entering powder interval；
Operating process：Exemplified by the 2 points of sprayings of certain type part, control detonation flame spraying technological procedure carries out technique examination to testpieces
Requirement is tested, detailed process step is as follows：
It is loaded and part and starts plasma spraying equipment, according to the positions of two spraying points, manually adjusts spray gun and move left and right limit
Bit switch position, to set spraying point position；On touch screen operation panel, selection is by point spray coating operations mode；Press startup
Button, sets spray gun number；Automatic button is pressed, spray gun is moved to the left automatically, be moved to the left limit position of the switch, spray gun stops
Motion, control system automatically turns on oxygen valve, nitrogen valve, acetylene valve, powder feeding nitrogen valve and igniting, completes the spraying work of a rifle
Make；Control system repeats to open igniting according to the rifle number of setting, until actual spray gun number is equal to the rifle number of setting, left-hand point
Spray coating operations terminate；Spray gun moves right automatically, is moved to the right limit position of the switch, and spray gun stop motion, control system is automatic
Oxygen valve, nitrogen valve, acetylene valve, powder feeding nitrogen valve and igniting are opened, the spray coating operations of a rifle are completed；Control system is according to setting
Rifle number, repeat to open igniting, until actual spray gun number is equal to the rifle number set, right-hand point spray coating operations terminate；Complete examination
Test and examine.
