Ulwazi oluthile oluyisisekelo lobuchwepheshe bokusika nge-laser

Isimiso sokusebenza sokusika nge-laser

Ukusika nge-laser kufakwe ijeneretha ye-laser ekhipha umsebe we-laser onamandla aphezulu. Umsebe we-laser uzobe usugxilwe ilensi bese wakha indawo encane kakhulu yokukhanya enamandla aphezulu. Ngokugxilisa indawo yokukhanya ezindaweni ezifanele, izinto zizomunca amandla avela ekukhanyeni kwe-laser bese zihwamuka, zincibilikise, zisuse noma zifinyelele endaweni yokushisa. Ngemuva kwalokho umoya osizayo ocindezelekile kakhulu (i-CO2, i-Oxygen, i-Nitrogen) uzophephula insalela yemfucuza. Ikhanda le-laser liqhutshwa yi-servo motor elawulwa uhlelo futhi ihamba ngendlela enqunywe kusengaphambili ezintweni ukuze inqume izingcezu zomsebenzi zezimo ezahlukene.

Izinhlobo zamajeneretha e-laser (imithombo ye-laser)

Ukukhanya kungahlukaniswa ngokukhanya okubomvu, ukukhanya okusawolintshi, ukukhanya okuphuzi, ukukhanya okuluhlaza njalo njalo. Kungamuncwa noma kuboniswe yizinto. Ukukhanya kwe-laser nakho kuwukukhanya. Futhi ukukhanya kwe-laser okunobude obuhlukile bokukhanya kunezici ezahlukene. I-gain medium yejeneretha ye-laser okuyiyona medium eguqula ugesi ube yi-laser inquma ubude bokukhanya, amandla okukhipha kanye nokusetshenziswa kwe-laser. Futhi i-gain medium ingaba yisimo segesi, isimo soketshezi kanye nesimo esiqinile.

1. I-laser yesimo segesi ejwayelekile kakhulu yi-laser ye-CO2;

2. I-laser yesimo esiqinile ejwayelekile kakhulu ifaka phakathi i-fiber laser, i-YAG laser, i-laser diode kanye ne-ruby laser;

3. I-laser yesimo soketshezi isebenzisa ezinye izinto eziwuketshezi njenge-organic solvent njengendlela yokusebenza ukukhiqiza ukukhanya kwe-laser.

Izinto ezahlukene zimunca ukukhanya kwe-laser kwamaza ahlukene. Ngakho-ke, ijeneretha ye-laser kumele ikhethwe ngokucophelela. Embonini yezimoto, i-laser esetshenziswa kakhulu yi-laser ye-fiber.

Izindlela zokusebenza zomthombo we-laser

Umthombo we-laser uvame ukuba nezindlela zokusebenza ezintathu: imodi eqhubekayo, imodi yokushintshashintsha kanye nemodi yokushaya kwenhliziyo.

Ngaphansi kwemodi eqhubekayo, amandla okukhipha e-laser ahlala njalo. Lokhu kwenza ukushisa okungena ezintweni kulingane, ngakho-ke kufanelekile ukusika isivinini. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi kungenza umonakalo omkhulu endaweni ethinta ukushisa.

Ngaphansi kwemodi yokushintshashintsha, amandla okukhipha e-laser alingana nomsebenzi wejubane lokusika. Ingagcina ukushisa okungena ezintweni ezingeni eliphansi ngokunciphisa amandla endaweni ngayinye ukuze kugwenywe umkhawulo wokusika ongalingani. Njengoba ukulawula kwayo kuyinkimbinkimbi kancane, ukusebenza kahle akuphezulu futhi kungasetshenziswa isikhathi esifushane kuphela.

Imodi yokushaya ingahlukaniswa ibe yimodi yokushaya evamile, imodi yokushaya enamandla kakhulu kanye nemodi yokushaya enamandla kakhulu. Kodwa umehluko wabo oyinhloko uwumehluko wokuqina kuphela. Abasebenzisi bangenza isinqumo ngokusekelwe ezicini zezinto kanye nokunemba kwesakhiwo.

Ngamafuphi, i-laser ivame ukusebenza ngaphansi kwemodi eqhubekayo. Kodwa ukuze uthole ikhwalithi yokusika elungiselelwe, kwezinye izinhlobo zezinto, kuyadingeka ukulungisa isivinini sokuphakelayo, njengokusheshisa, ukusika isivinini kanye nokubambezeleka lapho ujika. Ngakho-ke, ngaphansi kwemodi eqhubekayo, akwanele nje ukwehlisa amandla. Amandla e-laser kumele alungiswe ngokushintsha i-pulse.

Ukusika kwe-laser kwepharamitha

Ngokwezidingo zomkhiqizo ezahlukene, kuyadingeka ukuqhubeka nokulungisa amapharamitha ngaphansi kwezimo zokusebenza ezahlukene ukuze uthole amapharamitha angcono kakhulu. Ukunemba kokubeka okujwayelekile kokusika nge-laser kungafika ku-0.08mm kanti ukunemba kokubeka okuphindaphindwayo kungafika ku-0.03mm. Kodwa esimweni sangempela, ukubekezelela okuncane kufana no-±0.05mm wokuvula kanye no-±0.2mm wendawo yembobo.

Izinto zokwakha ezahlukene kanye nobukhulu obuhlukene kudinga amandla ahlukene okuncibilikisa. Ngakho-ke, amandla okukhipha adingekayo e-laser ahlukile. Ekukhiqizeni, abanikazi befektri kudingeka benze ibhalansi phakathi kwesivinini sokukhiqiza kanye nekhwalithi bese bekhetha amandla okukhipha afanele kanye nesivinini sokusika. Ngakho-ke, indawo yokusika ingaba namandla afanele futhi izinto zingancibilikiswa ngempumelelo enkulu.

Ukusebenza kahle kwe-laser ukuguqula ugesi ube amandla e-laser kungama-30%-35%. Lokho kusho ukuthi ngamandla okufaka angaba ngu-4285W ~ 5000W, amandla okukhipha angaba ngu-1500W kuphela. Ukusetshenziswa kwamandla okufaka kukhulu kakhulu kunamandla okukhipha ajwayelekile. Ngaphandle kwalokho, ngokomthetho wokulondolozwa kwamandla, amanye amandla aphenduka ukushisa, ngakho-ke kuyadingeka ukwengeza umshini wokupholisa amanzi wezimboni .

I-S&A ingumkhiqizi we-chiller othembekile onolwazi lweminyaka engu-19 embonini ye-laser. Ama-water chiller ezimbonini awakhiqizayo afanelekela ukupholisa izinhlobo eziningi zama-laser. I-fiber laser, i-CO2 laser, i-UV laser, i-ultrafast laser, i-laser diode, i-YAG laser, ukubala ezimbalwa. Zonke ama-chiller e-S&A akhiwe ngezingxenye ezivivinywe isikhathi ukuqinisekisa ukusebenza okungenazinkinga ukuze abasebenzisi baqiniseke ukuthi bayazisebenzisa.
