Okugezesa okunoonyereza kwa ssaayansi (okwekenneenya spektrum, laser-induced breakdown spectroscopy LIBS)

Obulungi bw’obujjanjabi (okuggyawo langi, okulongoosa nga tekuyingirira nnyo).

Ebipimo ebikulu:

Obuwanvu bw’amayengo: 532nm (ekitangaala kya kiragala) oba 355nm (ultraviolet)

Obugazi bwa pulse: 1.8 ~ 2ns

Okuddiŋŋana frequency: 500Hz ~ 200kHz okutereezebwa

Amaanyi ag’oku ntikko: density y’amasoboza amangi, agasaanira okukola ebyuma ebituufu.

2. Enkola z’okuddaabiriza buli lunaku

(1) Okuddaabiriza enkola y’amaaso

Okukebera buli lunaku buli wiiki:

Okuddaabiriza mu bujjuvu buli luvannyuma lwa myezi esatu:

Kozesa ekyuma eky’enjawulo eky’okuyonja amaaso + ppamba ataliimu nfuufu okusiimuula lenzi (tokozesa mwenge okwewala okwonooneka kw’ekizigo).

Zuula obutambuzi bwa kirisitaalo ya layisi (nga Nd:YVO4) era ogizzeemu bwe kiba kyetaagisa.

(2) Enzirukanya y’enkola y’okunyogoza

Okuddaabiriza amazzi aganyogoza:

Kozesa amazzi agataliimu ayoni + ekiziyiza okukulukuta, zzaawo buli luvannyuma lwa myezi 6.

Kebera okusiba ekiyungo kya payipu y’amazzi okuziyiza okukulukuta.

Okwoza radiator:

Okwoza enfuufu ku ssanduuko y’ebbugumu enyogoza empewo buli luvannyuma lwa myezi 3 (okukakasa nti ebbugumu limala bulungi).

(3) Okukebera amasannyalaze n’ebyuma

Okutebenkera kw’amasannyalaze:

Londoola enkyukakyuka ya vvulovumenti eyingizibwa (obwetaavu <±5%), kirungi okussaamu ekiziyiza vvulovumenti ya UPS.

Kebera oba current ya pump diode (LD) drive current ya bulijjo.

Okufuga obutonde bw’ensi:

Ebbugumu ly'okukola 15 ~ 25 ° C, obunnyogovu <60%, weewale okufuumuuka.

3. Ensobi eza bulijjo n’okuzuula obulwadde

(1) Amaanyi agafuluma ga layisi gakendeera

Ebiyinza okuvaako ensonga eno:

Obujama bwa lenzi y’amaaso oba okwonooneka kw’ekizigo

Laser crystal (Nd:YVO4/YAG) okukaddiwa oba ebbugumu lenzi effect

Obulung’amu bwa Pump diode (LD) bukendeera.

Emitendera gy’okuzuula obulwadde:

Kozesa mita y’amaanyi okuzuula amaanyi agafuluma.

Kebera ekkubo ly’amaaso mu bitundu (yawula ekituli ekiwuuma era ogezese omulimu gwa modulo emu).

(2) Obutabeera mu ntebenkevu mu pulse oba okubula

Ebiyinza okuvaako ensonga eno:

Q switch (nga acousto-optic modulator AOM) okulemererwa kwa drive

Control circuit board (nga FPGA timing board) siginiini etali ya bulijjo

Amasannyalaze ga modulo y’amasannyalaze tegamala.

Emitendera gy’okuzuula obulwadde:

Kozesa oscilloscope okuzuula siginiini ya Q switch drive.

Kebera oba ensengeka ya frequency y’okuddiŋŋana esukka ekkomo.

(3) Alaamu y’enkola y’okunyogoza

Ebiyinza okuvaako ensonga eno:

Okutambula kw’amazzi aganyogoza obutamala (okulemererwa kwa ppampu y’amazzi oba payipu okuzibikira) .

TEC (thermoelectric cooler) okulemererwa

Sensulo y’ebbugumu ewuguka.

Emitendera gy’okuzuula obulwadde:

Kebera omutindo gwa ttanka y’amazzi n’okusengejja.

Pima oba vvulovumenti esala TEC ya bulijjo.

(4) Ekyuma tekisobola kutandika

Ensonga eziyinza okubaawo:

Amasannyalaze amakulu agonoonese (fiyuzi efuuwa) .

Safety interlock ekolebwa (nga chassis obutaggaddwa) .

Fuga ensobi mu mpuliziganya ya pulogulaamu.

Emitendera gy’okuzuula obulwadde:

Kebera amasannyalaze agayingira ne fiyuzi.

Ddamu okutandika software era oddemu okuteeka driver.

4. Okuddaabiriza ebirowoozo n’enkola

(1) Okugonjoola ebizibu mu modulo

Ekitundu eky’amaaso:

Okwoza oba zzaawo lenzi erimu obucaafu → Ddamu okupima ekkubo ly’amaaso.

Ekitundu ekifuga ebyuma bikalimagezi:

Kikyuseemu ekipande kya ddereeva wa switch ya Q eyonoonese → Kalibrate obudde bwa pulse.

Ekitundu ekinyogoza:

Sumulula payipu ezibiddwa → Kikyuseemu ppampu y’amazzi/TEC eriko obuzibu.

(2) Okupima n’okugezesa

Okuzuula pulse: Kozesa photodetector + oscilloscope ey’amaanyi okukakasa obugazi bwa pulse n’obutebenkevu.

Okwekenenya omutindo gw’ebikondo: Kozesa mita ya M2 okukakasa nti enkoona y’okuwukana kw’ebikondo etuukana n’omutindo.

(3) Ebiteeso ku kulonda sipeeya

Sipeeya ow’olubereberye (nga modulo za LD ne switch za Q eziweebwa GWU/Laser Components) ze zisinga okwettanirwa.

Ekirala: sipeeya ow’ekika eky’okusatu akwatagana ennyo (okukwatagana kwa parameter kwetaaga okukakasibwa).

5. Enteekateeka y’okuddaabiriza okuziyiza

Buli mwezi: wandiika amaanyi agafuluma n’emitendera gya parameter ya pulse.

Buli luvannyuma lwa myezi mukaaga: okupima ebituli by’amaaso nga bayinginiya abakugu.

Buli mwaka: okwekenneenya okujjuvu enkola y’okunyogoza n’okukaddiwa kwa modulo y’amasannyalaze.

Mu bufunzi

Okuyita mu standardized daily maintenance + modular maintenance ideas, obulamu bwa YLPN laser busobola okugaziwa ennyo era downtime esobola okukendeezebwa. Bw’oba ​​weetaaga obuyambi obw’obwegendereza, wulira nga oli waddembe okutuukirira ttiimu yaffe ey’ekikugu
