Ukugcina ubuqotho bemishini yokucindezela kuyinto eqhubekayo kunoma yimuphi umnikazi/umqhubi. Abanikazi/abaqhubi bemishini efana nezitsha, izitofu, ama-boiler, ama-exchange, amathangi okugcina izinto, kanye namapayipi kanye nezinsimbi ezihlobene bathembele ohlelweni lokuphatha ubuqotho ukuhlola ukuthembeka kwemishini nokuvikela ubuqotho bemishini ukuze kusebenze ngokuphepha nangokusebenza kahle. Amasu ahlukahlukene angonakalisi avame ukusetshenziswa ukuqapha izingxenye ezibalulekile, njengoba ukuqonda insimbi efanele yalezi zingxenye kubalulekile ekwethembekeni kwazo nasekusebenzeni ngokuphephile. Ukusebenzisa uhlobo olungalungile lwezinto kungaba nemiphumela emibi kakhulu.
Ukuhlola ezinye zalezi zingxenye (njengezingxenye ezincane noma ama-piping assemblies) ukuhlaziywa kwekhabhoni kanye namazinga ezinto kungaba yinselele ngenxa ye-geometry noma usayizi. Ngenxa yobunzima bokuhlaziya izinto, lezi zingxenye zivame ukukhishwa ohlelweni lwe-Positive Material Identification (PMI). Kodwa awukwazi nje ukungazinaki noma yiziphi izingxenye ezibalulekile, kufaka phakathi amapayipi amancane amakhulu. Ingxenye encane ehlulekayo ohlelweni olubalulekile ingaba nomthelela ofanayo nokwehluleka kwengxenye enkulu. Imiphumela yokwehluleka ingaba mincane, kodwa imiphumela ingaba efanayo: umlilo, isikhathi sokungasebenzi kwesitshalo senqubo, kanye nokulimala.
Njengoba i-Laser Induced Breakdown Spectroscopy (LIBS) isishintshele ezindleleni zokuhlaziya zelabhorethri yaya kwejwayelekile, ikhono lokwenza ukuhlolwa kwekhabhoni okungu-100% okudingekayo kwazo zonke izingxenye ezisensimini liyigebe elikhulu embonini elisanda kugcwaliswa ngamasu okuhlaziya. Lobu buchwepheshe obuphathwa ngesandla buvumela abanikazi/abaqhubi ukuthi bahlole ngokuthembekile nangokunembile lezi zingxenye ukuze bathole ukuhambisana nenqubo yezinto ezibonakalayo futhi buhlinzeka ngesisombululo esiphelele sokuqinisekiswa kwezinto ezisezindaweni okuhlanganisa nokuhlaziywa kwekhabhoni.
Umfanekiso 1. Ukuhlaziywa Kwekhabhoni Kwe-SciAps Z-902 ER308L Weld ¼” Umthombo Obanzi: SciAps (Chofoza isithombe ukuze ukhulise.)
I-LIBS iyindlela yokukhipha ukukhanya esebenzisa i-laser evunguzayo ukuze isuse ubuso bento futhi idale i-plasma. I-spectrometer esebhodini ilinganisa ukukhanya kusuka ku-plasma ngokwekhwalithi, ihlukanise ubude bamaza ngamunye ukuze iveze okuqukethwe okuyisisekelo, okube sekulinganiswa ngokulinganiswa okusebhodini. Ngezinto ezintsha zakamuva ezihlaziyi ze-LIBS eziphathwayo, kufaka phakathi izimbobo ezincane kakhulu zokuphuma, umoya we-argon ongasebenzi ungatholakala ngaphandle kokuvala izindawo ezigobile noma izingxenye ezincane, okwenza ochwepheshe bakwazi ukuhlola izingxenye kungakhathaliseki usayizi noma i-geometry. Ochwepheshe balungisa izindawo, basebenzisa amakhamera angaphakathi ukuze bahlole izindawo futhi bazihlaziye. Indawo yokuhlola ingama-micron angaba ngu-50, okuzovumela ochwepheshe ukuthi balinganise izingxenye zanoma yiluphi usayizi, kufaka phakathi izingxenye ezincane kakhulu, ngaphandle kwesidingo sama-adapter, ukuqoqa izingcezu, noma ukuthumela izingxenye ezizidelayo elabhorethri.
Abakhiqizi abaningana bakhiqiza abahlaziyi be-LIBS abaphathwa ngesandla abatholakala kwezentengiselwano. Uma befuna i-analyzer efanele yohlelo lwakho lokusebenza, abasebenzisi kudingeka bakhumbule ukuthi akuwona wonke ama-analyzer e-LIBS aphathwa ngesandla adalwe ngokulinganayo. Kunezinhlobo eziningana zama-analyzer e-LIBS emakethe avumela ukuhlonza izinto, kodwa hhayi okuqukethwe yi-carbon. Kodwa-ke, ezicelweni lapho kudingeka khona amamaki ezinto, i-carbon iyalinganiswa futhi izinto zilinganiswa ngokusekelwe enanini le-carbon. Ngakho-ke, i-carbon ibalulekile ohlelweni lokuphatha ubuqotho oluphelele.
Umfanekiso 2. Ukuhlaziywa kwekhabhoni ye-SciAps Z-902 yesikulufu somshini esingu-1/4-intshi, izinto ezingu-316H. Umthombo: SciAps (Chofoza isithombe ukuze usikhulise.)
Isibonelo, insimbi yekhabhoni engu-1030 ihlonzwa ngokuqukethwe kwekhabhoni okusentweni, kanti izinombolo ezimbili zokugcina egameni lento zikhomba okuqukethwe kwekhabhoni okujwayelekile - i-0.30% yekhabhoni iyikhabhoni engavamile ensimbini yekhabhoni engu-1030. Lokhu kusebenza nakwezinye izinsimbi zekhabhoni ezifana nensimbi engagqwali engu-1040, insimbi yekhabhoni engu-1050, njll. Noma uma ulinganisa insimbi engagqwali engu-300 yochungechunge, okuqukethwe kwekhabhoni kuyisici esiyisisekelo esidingekayo ukukhomba ibanga le-L noma le-H lento, njengezinto ezingu-316L noma ezingu-316H. Uma ungalinganisi ikhabhoni, umane ukhomba uhlobo lwento hhayi ibanga lezinto.
Umfanekiso 3. Ukuhlaziywa kwe-SciAps Z-902 Carbon kwe-1” s/160 A106 Fitting for HF Alkylation Services Source: SciAps (Chofoza isithombe ukuze ukhulise.)
Abahlaziyi be-LIBS abangenalo ikhono lokulinganisa ikhabhoni bangakwazi ukubona izinto zokwakha kuphela, ezifana nezinsimbi ze-X-ray fluorescence (XRF). Kodwa-ke, abakhiqizi abaningana bakhiqiza abahlaziyi bekhabhoni be-LIBS abaphathwa ngesandla abakwazi ukulinganisa okuqukethwe kwekhabhoni. Kunomehluko oyisisekelo phakathi kwabahlaziyi njengosayizi, isisindo, inani lokulinganisa elitholakalayo, isikhombimsebenzisi sesampula sezindawo ezivaliwe uma kuqhathaniswa nezingavaliwe, kanye nokufinyelela ezingxenyeni ezincane zokuhlaziya. Abahlaziyi be-LIBS abanezimbobo ezincane zokuphuma abadingi uphawu lwe-argon ukuze bahlolwe, futhi abadingi ama-adaptha ewijethi adingwa abanye abahlaziyi be-LIBS noma amayunithi e-OES ukuze bahlole amawijethi. Inzuzo yale ndlela ukuthi ivumela ochwepheshe ukuthi bahlole noma iyiphi ingxenye yenqubo ye-PMI ngaphandle kokusebenzisa ama-adaptha akhethekile. Abasebenzisi badinga ukufunda imisebenzi ehlukahlukene yesihlaziyi ukuze banqume ukuthi ithuluzi lingahlangabezana yini nezidingo zesicelo esihlosiwe, ikakhulukazi uma isicelo sidinga i-PMI engu-100%.
Amakhono ezinsimbi ze-LIBS eziphathwayo ashintsha indlela yokuphathwa kokuhlaziywa kwensimu. Lezi zinsimbi zinikeza umnikazi/umqhubi indlela yokuhlaziya izinto ezingenayo, izinto ze-PMI ezisetshenziswayo/zakudala, ama-weld, izinto ezisetshenziswayo zokushisela, kanye nanoma yiziphi izingxenye ezibalulekile ohlelweni lwabo lwe-PMI, zinikeza ikhambi elisebenzayo nelithembekile lanoma yiluphi uhlelo lobuqotho bempahla. Isixazululo esingabizi kakhulu ngaphandle komsebenzi owengeziwe noma izindleko zokuthenga izingxenye ezizidelayo noma ukuqoqa izingcezu bese uzithumela elabhorethri bese ulinda imiphumela. Lezi zihlaziyi ze-LIBS eziphathwayo, eziphathwa ngesandla zinikeza abasebenzisi ukusebenza okwengeziwe okwakungekho eminyakeni embalwa edlule.
Umfanekiso 4. Ukuhlaziywa Kwekhabhoni Kwentambo Ye-SciAps Z-902 1/8”, Umthombo Wezinto Ezingu-316L: SciAps (Chofoza isithombe ukuze ukhulise.)
Ukuthembeka Kwempahla kufaka phakathi uhlelo oluphelele lokuqinisekisa izinto, olusetshenziswa ngokugcwele emkhakheni, ukuqinisekisa ukuhambisana kwemishini kanye nokusebenza okuphephile nokusebenza kahle. Ngocwaningo oluncane ku-analyzer efanele kanye nokuqonda uhlelo lokusebenza, abanikazi/abaqhubi manje sebengakwazi ukuhlaziya nokubeka amazinga ngokuthembekile noma yimiphi imishini ohlelweni lwabo lobuqotho bempahla, kungakhathaliseki ukuthi i-geometry noma usayizi, futhi bathole ukuhlaziywa kwesikhathi sangempela. Izingxenye ezibalulekile ze-small-bore manje zingahlaziywa ngokushesha, ngokuzethemba nangokunembile zinikeze abanikazi/abasebenzisi idatha edingekayo ukuze benze izinqumo ezibalulekile zokuvikela ubuqotho bemishini.
Lobu buchwepheshe obusha buvumela abanikazi/abaqhubi ukuthi balondoloze izinga eliphezulu lobuqotho nokuthembeka kwemishini yabo ngokugcwalisa izikhala ekuhlaziyweni kwensimu yekhabhoni.
