Imiterere ibiri y'umushinga igabanya ihindagurika ry'ibicirourugi rw'uruzigavuba kurusha ibindi byose: umwuka w'umunyu, no gukoreshwa buri gihe. Bigenda birushaho kwiyongera.
Imyitozo yo gupima ibintu ifite akamenyero ko gutwara ikintu cyavuye mu mushinga uheruka. Iteranya ry'ibiziga byakozwe neza mu biro byo mu gihugu rishyirwa muri hoteli iri ku mucanga, aho abagenzi banyura cyangwa aho ibitaro bihurira - hanyuma bikananirwa mu gihe cy'ingwate. Impamvu si uko ibikoresho byari bifite inenge. Ni uko ibintu bibiri bihindura ibidukikije byahindutse icyarimwe, kandi nta na kimwe cyanditse mu bipimo.
Impinduka zombi ubu zoroshye kuzisobanura ugereranyije n’uko byari bimeze mu myaka icumi ishize. Isuzuma ry’amagare n’isuzuma ry’umunyu ryavuye ku bintu by’inyongera by’inyongera bijya ku bintu by’inyongera, kandi amahame ari inyuma yabyo yaravuguruwe kugira ngo ahuze n’imisoro y’ubucuruzi aho kuba iy’abaturage.
Igitutu cy’ubucuruzi kiri inyuma y’iryo hinduka kirapimwa. Sisitemu zo kuzunguruka zikomeje kugira uruhare mu myanya yo guturamo n’iy’ubucuruzi, kandi ikoranabuhanga ririmo kongeramo imigendekere y’akazi: guhuza sisitemu zo kuzunguruka zikoresha ikoranabuhanga mu mazu agezweho n’ahantu ho gucururiza bitera hafi 20% by’iterambere ry’ibikoresho byo kuzunguruka, nk’uko Business Research Insights ibivuga, mu gihe ukwiyongera kw’ibiciro byo kuzigama umwanya bingana na 35%. Ikoranabuhanga rihindura ikibazo cy’imiterere, kuko urugi rukoresha amashanyarazi rukunze kuzunguruka cyane kurusha urw’intoki kandi ntirushobora kwishingikiriza ku mukoresha worohereza agace karwo guhagarara.
Uburyo bubiri bwo gutsindwa, ibipimo bibiri bitandukanye
Guhura n’inkombe byibasira ibikoresho. Umwuka wuzuyemo umunyu, ubushuhe buzenguruka hamwe na koloride yo mu kirere byihutisha ingese ku bice by’icyuma, kandi ibyangiritse byibanda ahantu bigoye kugenzura: imigendekere y’ibyuma, imigozi y’imizingo n’ubuso bw’inzira. Gutera ku ruziga rw’umuzingo byongera gukururana, gukururana byongera imbaraga zo gukurura umuntu yumva, kandi amaherezo agace k’umuzingo karakururana cyangwa kagasohoka.
Imodoka nyinshi zitwara abantu zibangamira imikorere y’imodoka. Imashini itwara abantu mu rugo ishobora kugenda inshuro ibihumbi bike mu mwaka. Irembo ry’ubucuruzi muri sitasiyo y’ubwikorezi cyangwa mu bitaro rishobora kugenda inshuro ibihumbi mirongo mu gihe kimwe - kandi inzugi zikoresha ikoranabuhanga ryongera kugwiza ibyo, kuko sisitemu yo gutwara imodoka idatuma ihagarara nk’uko umuntu abigenza.
Ingaruka zifatika: imiterere y’inkombe igomba kuba ishingiye ku bikoresho no kugenzura irangi, mu gihe imiterere y’urujya n’uruza rw’abantu benshi igomba kuba ishingiye ku gihe cy’uruziga rwanditse. Imishinga iri ku nkombe n’iy’uruza rw’abantu benshi ikeneye ibisabwa bibiri bikusanyijwe, ntibihuzwe.
Ibyo imishinga yo ku nkombe z'inyanja igomba kugaragaza
Guhitamo ibikoresho bidakoresha icyuma gifunganye, ntabwo ari "bitarimo icyuma gifunganye" gusa. Icyiciro cya 304 ni ikintu gisanzwe gikoreshwa kandi kirahagije ku hantu hihishe mu gihugu imbere. Ku bijyanye no kugera ku nkombe z'inyanja, ipine y'icyuma gifunganye iri mu cyiciro cya 316 ni yo mahitamo yagenwe cyane kubera ko ifite molybdenum kandi ikaba ifite ubushobozi bwo kurwanya chloride; ipine y'icyuma gifunganye ya 304 igomba gufatwa nk'amahitamo yo kwinjira mu gihugu imbere aho gufatwa nk'amahitamo yo kwinjira mu nkombe. Aho ibikoresho bihuye n'imiterere ya aluminiyumu, hagomba gushyirwaho imashini zigabanya cyangwa irangi rijyanye nabyo kugira ngo hirindwe ibibazo bya galvanic aho gushingwa.
Igihe cyavuzwe cyo gusukura umunyu n'uburyo bwo kuwusukura. ASTM B117 ni bwo buryo bukoreshwa cyane mu gusukura umunyu; ISO 9227 ni yo ngano mpuzamahanga. Mu by'ukuri, aya mahame agena uburyo bwo gupima, ntabwo ari urwego rwo kunyuramo - igihe cyo gusukura gisabwa gituruka ku bipimo by'umushinga cyangwa ku gipimo cy'umukiriya. Ibyiciro bisanzwe byo gusukura ni amasaha 96, 240 na 500 yo gusukura ASTM B117, aho igihe cy'amasaha 1.000 cyangwa arenga kigaragara mu mishinga yo ku nkombe no mu mazi yegereye. Ibipimo bigomba kuvuga uburyo n'amasaha, hamwe n'igipimo cyo kwemerwa (urugero, nta ngese itukura n'ijanisha ntarengwa rya corruption yera).
Amateraniro afunze neza kandi yasizwe amavuta mbere. Gushyira amavuta ku ruziga rw'umuzingo ku nkombe y'inyanja ntabwo ari ingirakamaro cyane. Amateraniro afunze neza afite igihe runaka cyo gukora akazi gakuraho akazi ko kubungabunga amakipe menshi y'ibigo adashobora gukora mu buryo bufatika.
Ibyo imishinga ihura n'abantu benshi igomba kugaragaza
Amakuru y’ikizamini cy’ubuzima bw’uruziga akoresheje uburyo bwitwa. ANSI/BHMA A156.14 ishyiraho ibisabwa mu bikoresho by’inzugi zinyerera n’izizunguruka kandi ikubiyemo ibizamini by’uruziga, gukurura nabi, gukomera kw’umutwaro uhamye, uburyo bworoshye, gushyamirana kw’umutwaro uhamye n’umutwaro ugoye. Ivugurura rya 2024 rigaragaza uburyo ibikoresho byo mu rugo n’ubucuruzi bikoreshwa ubu. Ku nzugi zinyerera n’izizunguruka zikoresha ingufu nke, ANSI/BHMA A156.38 isaba uruziga 300.000, igihe cyo gufungura no gufunga kigomba kuba kiri hagati ya -10% na +20% by’agaciro kanditswe mu ntangiriro y’ikizamini - icyitegererezo cy’ingirakamaro cy’uko ikirego cy’uruziga kigomba kwemezwa.
Ingano y'umutwaro iri hejuru y'uburemere bw'umukandara wabazwe. Ipine y'umuzingo iremereye igomba kugenwa n'umutwaro wayo ugenwe, ntabwo igenwa n'ikimenyetso kiri ku ipaji ya kataloge.Ipine y'urukiramendeIbipimo by'imitwaro bigomba kugereranywa n'uburemere bw'aho hantu hiyongereyeho ubushyuhe, ibikoresho n'umutwaro w'umuyaga ku maso yo hanze. Intego ni uko ikigereranyo, atari ukureba, ari cyo: ishusho y'umutwaro igomba kuba hejuru y'umutwaro wa serivisi wabazwe.
Ingano yo gukosora igaragazwa muri milimetero. Ibikoresho bishobora guhindurwa uburebure byemerera abashyiraho ibikoresho gukurura no gukurikirana ubushobozi bw'ibikoresho aho bikorerwa. Mu mishinga ikunze kugaragara cyane, ubwo buryo bwo gukosora ni bwo butuma ikosa rya mbere ritahinduka itegeko ryo gusimbuza.
Imirongo itandatu ijyanye na buri gipimo cy'uruziga rw'umuzingo
- Ibikoresho by'uruziga rw'umuzingo n'urwego rwarwo (urugero, uruziga rw'umuzingo rwa 316 rudasagwa ku nkengero z'inyanja, cyangwa uruziga rwa nylon aho gukora ahantu hatuje bivuze kuruta umutwaro).
- Ubwoko bw'ibyuma — bifunze neza, byasizwe amavuta mbere, kandi igihe cyabyo cyo gukora cyagenwe.
- Igipimo cy'umutwaro kuri buri ruziga rw'umuzingo, hashingiwe ku isuzuma ryagaragajwe.
- Ikirego cy'ubuzima bw'uruziga hamwe n'uburyo bw'ikizamini cyujuje ibisabwa hamwe n'umubare w'uruziga.
- Ibipimo bya ingese — uburyo busanzwe bwo gukoresha hamwe n'amasaha asabwa yo kwigaragaza hamwe n'ibipimo ngenderwaho byo kwemerwa.
- Gukurikirana ibintu — ibyemezo by’ibikoresho byo ku rwego rw’itsinda, birushaho guherekeza gahunda y’ibikoresho mu gutanga amasoko.
Aho ibintu byombi bihurira
Ubwoko bw'imishinga ihuza umwuka w'umunyu n'ikoreshwa rikomeye buri kwiyongera cyane kurusha icyiciro kimwe: aho ubwato butwara abantu n'ibintu bitwara abagenzi, ibitaro n'amavuriro yo ku nkombe z'inyanja, aho abagenzi banyura mu nyanja, aho binjirira mu biruhuko, aho bacururiza ku nkengero z'inyanja n'aho bakorera ubushakashatsi ku mazi. Muri izi nyubako, amabwiriza y'uruziga rw'imodoka agomba kuba yujuje ibisabwa n'ibikenewe ku igare icyarimwe - kandi igice gisanzwe ni umurongo wa nyuma usubirwamo mu ipaki yo gutanga serivisi kandi ni wo wa mbere utanga serivisi yo guhamagara.
Abashushanya imishinga nk'iyo barushaho gufata urukiramende n'inzira nk'igice kimwe cyagenwe aho gufata ibintu bibiri bya kataloge, kuko uburyo bwo gucika bukorana: ingese yongera gucika, gucikana byihutisha kwangirika, kandi kwangirika bigabanya igihe mbere y'uko habaho ihinduka rikurikira.
Aho ibipimo bikunze kuba bibi
Ikosa rikunze kugaragara ni ukwemera ikirego cy’ikizamini kidakoreshejwe uburyo bwacyo: "igeragezwa rya corrosion" na "igeragezwa rya cycle" ntacyo bivuze keretse havuzwe ibipimo ngenderwaho, igihe n'icyitegererezo cyo kwemerwa. Icya kabiri ni ukugaragaza amapine y’imizingo utitaye ku muhanda n’aho baca - ipine y’imizingo ihambaye ku muhanda udashobora kwihanganira ubwinshi izakomeza kwangirika. Icya gatatu ni ugufata imishinga yo ku nkombe n’imihanda itwara abantu benshi nk’ibyiciro bitandukanye mu gihe ubwoko bw’umushinga ukura vuba ari bwo bwombi.
Ingingo y'ingenzi
Ku mishinga yo ku nkombe z'inyanja n'iy'imodoka nyinshi,ipine ry'ikizingosi ikintu cy’ibicuruzwa. Ni igice aho ibintu bibiri bigoye cyane bihurira, kandi ni cyo gice gihendutse cyane cyo guteranya ibintu kugira ngo gisobanurwe cyane kandi ni cyo gihendutse cyane gusimbuza - ikosa ry’uruziga rw’umuzingo ku muryango w’umuzingo unyura ku nkombe akenshi rirangira nk’isimburana ry’uruziga rw’umuzingo; rirangira nk’ihinduranya ryuzuye ry’umuzingo. Ingano y’ibikoresho byo kwandika, uburyo bwo gupima, amasaha yo kugaragara n’ingendo bibarwa mu bisobanuro bitwara paragarafu. Kubisiga hanze bisaba garanti.
