Intangiriro

Guhitamo umunwa ukwiye w'umuriro mu nganda si icyemezo cyoroheje cy'ibikoresho; bigira ingaruka ku buryo butaziguye ku buryo bwo kugera ku isoko, kugenzura amazi atemba, ikwirakwizwa ry'ibikoresho, n'ubushobozi bwo gukumira inkongi z'umuriro zishyuha cyane kandi zishobora gutera ibyago byinshi. Ingaruka zitandukanye, kuva ku kubika amazi ashobora gushya kugeza ku bikoresho bitunganya n'aho bipakira, bisaba imiterere itandukanye y'imigezi, ingano y'umuvuduko, no guhuza na sisitemu z'amazi cyangwa ifuro. Iyi nkuru isobanura ibintu by'ingenzi bituma amazi atoranywa, harimo ubwoko bw'ikoreshwa, imikorere y'amazi asohora, imiterere y'imikorere, no guhuza sisitemu. Mu mpera, abasomyi bazaba bafite uburyo bwo guhuza umunwa ukoreshwa n'ingaruka z'inganda, ibisabwa mu mikorere, n'ingamba rusange zo kurinda inkongi.

Impamvu guhitamo utuzu tw'umuriro ari ingenzi mu mikorere y'inganda

Uburyo bwo kurinda inkongi z'inganda bushingiye cyane ku ikoreshwa ry'ibikoresho byo gukumira kugira ngo bigabanye ibyago bikomeye. Nubwo pompe, imiyoboro, n'imiyoboro yo gutahura ari byo bigize ibikorwa remezo by'uburyo bwo kurinda inkongi, umuyoboro w'umuriro ukora nk'intambwe y'ingenzi yo gutanga. Guhitamo umuyoboro ukwiye w'umuriro bigena niba amazi cyangwa ifuro bihari bizanyura neza mu mwobo w'ubushyuhe, bigakonjesha isoko y'ibikomoka kuri peteroli, kandi bikagera ku kuzimya. Guhitamo nabi bibangamira ingamba zose zo gukumira, bigatera kwangirika kw'inyubako, kwanduza ibidukikije, ndetse no gukomeretsa abakozi cyane.

Ingaruka ku mikorere yo guhonyora

Intego y'ibanze y'umuyoboro w'umuriro ni uguhindura ingufu zishobora guterwa n'amazi afite umuvuduko mu ngufu, bikayahindura umuyoboro usanzwe. Imikorere yo guhosha ishingiye ku kugera ku bunini bw'igitonyanga, aho kigera, n'umuvuduko mwiza w'amazi. Iyo ingano y'igitonyanga ari nto cyane, amazi ashobora guhinduka umwuka mbere y'igihe mu bushyuhe mbere yo kugera ku cyicaro cy'umuriro. Ku rundi ruhande, ibitonyanga binini cyane bishobora kubura ubuso bukenewe kugira ngo ubushyuhe bwihute bushobore kwinjiza. Ibikorwa by'inganda akenshi bisaba ko bitangwa cyane, akenshi hakoreshejwe imiyoboro minini ishobora gusohora hagati ya litiro 500 na 2.000 ku munota (GPM) kugira ngo itsinde umuvuduko munini w'ubushyuhe usanzwe ukoreshwa mu gutwara ibikomoka kuri peteroli mu nganda.

Ibidukikije by'inganda bikenerwa cyane

Ibidukikije by’inganda bikenerwa cyane—nk’inganda zitunganya peteroli, aho gucukura amabuye y’agaciro mu mazi, n’inganda zikora ibintu biremereye—bitanga imbogamizi zidasanzwe zitegeka guhitamo imiyoboro y’amazi. Ibi bikunze gushyira ibikoresho mu kirere cyangiza cyane, ubushyuhe bukabije bwo mu kirere burenga 1.000°F mu gihe cy’imvura ikwirakwira mu gace runaka, ndetse n’ingaruka zikomeye za mekanike. Imiyoboro isanzwe y’umuriro mu mujyi akenshi ntihagije kuri ibi bihe. Ahubwo, inyubako z’inganda zikenera ibikoresho byihariye bya metallurgike, nk’umuringa udashobora kwangirika cyangwa icyuma kidashonga, hamwe n’imiterere igezweho ya hydraulic kugira ngo ikomeze gukora neza mu gihe cy’ibikorwa birebire kandi bikomeye byo gukumira.

Ubwoko bw'utuzuzu tw'umuriro n'ibipimo by'ingenzi by'imikorere

Gusuzuma ubwoko bw'imizingo y'umuriro bisaba gusobanukirwa byimbitse amabwiriza y'amazi n'uburyo ahuzwa n'inganda zikoresha. Abaguzi bagomba gukoresha imiterere itandukanye, buri imwe ikozwe kugira ngo icunge uburyo amazi anyuramo, umuvuduko w'amazi n'imiterere y'imizingo mu buryo butandukanye.

Ubwoko bw'iminwa nyamukuru n'udusanduku two kuyikoresha

Ibyiciro by'ingenzi by'imiyoboro y'intoki n'iy'igenzura birimo umuyoboro woroshye, litiro idahinduka, litiro ishobora gutoranywa, n'imiyoboro yikora. Imiyoboro y'imiyoboro ikora neza itanga umugezi ukomeye ushobora kugera no kwinjira neza, ukora neza ku gitutu gito. Imiyoboro y'imiyoboro ikora neza itanga umuvuduko wihariye w'amazi ku gitutu gisanzwe, itanga uburyo bworoshye kandi bwizewe. Imiyoboro y'imiyoboro ikora neza yemerera abakoresha guhindura umuvuduko w'amazi bakoresheje icyuma kizenguruka mu gihe bakomeza kugira umuvuduko uhoraho. Imiyoboro yikora ifite umuvuduko w'imbere uhinduka ugana ku gitutu gihindagurika, ugakomeza kugera ku mugezi uhoraho nubwo imiterere y'amazi itandukanye.

Ibipimo by'ingenzi: umuvuduko, igitutu, imiterere

Ibipimo by'ingenzi bireba uburyo amazi anyuramo (apimwe muri GPM cyangwa litiro ku munota), umuvuduko (upimwe muri PSI cyangwa bar), n'ubushobozi bwo gukoresha imiterere y'amazi. Imiyoboro gakondo ihuza imiyoboro ihabwa amanota ku muvuduko usanzwe w'imikorere wa 100 PSI (bar 7). Ariko, kugira ngo bagabanye umunaniro w'umukoresha no gucunga uburyo amazi anyuramo, inganda nyinshi zikoresha imiyoboro ifite umuvuduko muto yagenewe gukora kuri 50 cyangwa 75 PSI mu gihe itanga GPM imwe. Guhindura imiterere y'amazi—kuva ku mugezi ugororotse kugera ku muvuduko munini w'igihu kugira ngo abakozi barinde kandi bashyire ubushyuhe—nabyo ni ingenzi cyane mu guhangana n'ingaruka mbi zitandukanye.

Ibipimo ngenderwaho byo kugereranya abaguzi b'inganda

Mu kugereranya imiyoboro y'amazi, abaguzi b'inganda bagomba gusuzuma imikorere myiza y'amazi, imikoranire y'ibikoresho, n'ubushobozi bwo gukora ukurikije ingaruka zihariye z'inyubako zabo.

Guhuza Akazu k'Inkongi y'Umuriro n'Ibibazo by'Ibiza

Umunwa w'umuriro ukora neza cyane ugira akamaro gusa iyo uhuye neza n'imiterere yihariye y'ibyago ndetse n'ibikorwaremezo bya hydraulic by'ikigo.

Ibikoresho bya lisansi, aho umuntu aba, n'ibikoresho byo guhumeka

Isesengura ry’ibyago rigena uburyo bwo gukumira n’uburyo bwo gutanga. Ingaruka zo mu cyiciro cya B zijyanye n’ibinyobwa bishobora gushya zisaba utuzuzi duhuye n’ibirungo bya foam. Igipimo cyo kurekura ubushyuhe (HRR) cy’ibinyabiziga runaka kigena igipimo cy’ingenzi cyo gukoresha. Urugero, kuzimya umuriro wa hydrocarbon utemba bisaba igipimo cy’ifuro cya 0.16 GPM kuri metero kare. Byongeye kandi, ahantu hafungiye hadafite umwuka mwiza ushobora gusaba imiterere miremire y’ibihu kugira ngo hakwirwe ubushyuhe n’imyuka ikonje vuba, mu gihe ahantu ho hanze ho gukorera ibigega hakenera imigezi igororotse kandi idashobora kugera ku muyaga.

Ikoreshwa ry'imiyoboro y'amazi, ipompo, amazi n'imashini ifuro

Umuyoboro w'umuriro ugomba gukora neza hamwe n'imiyoboro, ipompo, na sisitemu zo gupima. Gutakaza imbaraga mu miyoboro bigomba kubarwa kugira ngo igitutu gihagije gisigaye kigere ku mwobo winjiramo. Byongeye kandi, urujya n'uruza rw'imiyoboro rushobora kurenza ubushobozi bwa pompe yo kuzimya umuriro; gukoresha imiyoboro ibiri ya GPM 1.000 icyarimwe bisaba pompe ifite agaciro kari hejuru ya 2.000 GPM kugira ngo isobanure imikorere mibi ya sisitemu. Mu gihe ukoresha ifuro, umuyoboro ugomba gutanga umwuka ukwiye, akenshi ukagera ku gipimo cyo kwaguka kiri hagati ya 3:1 na 8:1 ku miyoboro idahumeka ikoreshwa hamwe n'ibinyabutabire bigezweho bya foam.

Amakosa asanzwe yo guhitamo

Ikosa rikunze kubaho mu kurinda inkongi z'inganda ni ukwirengagiza imbaraga z'imizingo, ibyo bigahungabanya umutekano w'umukoresha. Uburyo imizingo ikoreshwa mu kuyikoresha bungana neza n'umuvuduko n'umuvuduko. Urugero, 250 GPM inyura kuri 100 PSI ikora ibiro bigera kuri 126 by'imbaraga z'imizingo, birenga cyane urugero rwemewe rw'umutekano rw'ibiro 85 ku mukoresha umwe. Irindi kosa rikunze kugaragara ni ukudahuza amahame ngenderwaho y'imizingo—nk'ukugena imizingo y'imizingo y'igihugu (NH) ku kigo gifite imiyoboro y'imiyoboro y'igihugu (NPSH)—ibi bikaba bibuza ko ishyirwa mu bikorwa mu gihe cy'impanuka.

Ikiguzi cyo kubahiriza amategeko, kubungabunga, n'igihe cy'ubuzima

Uretse imikorere y’amazi mu ntangiriro, amakipe ashinzwe gutanga amasoko agomba gusuzuma ikiguzi cy’ubuzima bwose bw’imiyoboro y’umuriro, akareba uko amategeko akurikizwa, ibisabwa mu kubungabunga, n’uburyo bwo kuzigama ibicuruzwa byizewe.

Amahame ngenderwaho, ibyemezo, na politiki y'urubuga

Inzogera zo mu nganda zigomba kubahiriza amahame akomeye y’inganda n’ibyemezo by’abandi kugira ngo zizerwe kandi zihuze n’abashinzwe ubwishingizi. NFPA 1964 (Standard for Spray Nozzles) ishyiraho ibipimo by’imiterere, imikorere, n’ibizamini bikomeye. Urugero, inzogera zujuje ibisabwa zigomba gutsinda neza ikizamini cy’umuvuduko wa hydrostatic kuri 900 PSI nta kibazo cy’imiterere. Byongeye kandi, inyubako akenshi zikenera ibikoresho kugira ngo zikore FM Approvals cyangwa UL listings, zemeza ko inzogera zakorewe ibizamini byigenga kandi byangiza kugira ngo zemeze koumuhinziibisabwa ku musaruro.

Igenzura, amahugurwa, no kuramba

Kuramba bigira ingaruka zitaziguye ku gihe cyo kubungabunga no ku giciro cy’ubuzima rusange. Utuzu twakozwe muri aluminiyumu ikozwe muri anodized aluminium (Mil-Spec Type III) dutanga igisubizo cyoroheje kibereye sisitemu z’amazi meza, ariko dushobora kwangirika vuba mu bidukikije bya peteroli. Ku rundi ruhande, utuzu twa brass cyangwa bronze dutanga ubudahangarwa bukomeye ku kirere cyangiza n’amazi y’umunyu, akenshi tugashobora kugera ku myaka 15 kugeza kuri 20, nubwo dufite uburemere bwinshi cyane. Igenzura rihoraho n’isuzuma ry’amazi, ryategetswe buri mwaka na NFPA 1962, ni ngombwa kugira ngo harebwe ko imitsi yo mu mutima, amenyo azunguruka, n’utuzu twa shutoff valves bikomeza gukora neza.

Isuzuma ry'umucuruzi n'isoko ry'umutungo

Gusuzuma abacuruzi bikubiyemo gusesengura ubushobozi bwabo mu gukora, inzira zo kwemeza ubuziranenge, n'uburyo bwo kwizerwa mu bijyanye n'ibikoresho. Abaguzi b'inganda bagomba gusuzuma amasezerano y'ubwishingizi bw'umucuruzi, uburyo ibikoresho bisimburana biboneka, na serivisi z'ubufasha mu bya tekiniki. Ibintu by'uruhererekane rw'ibicuruzwa ni ingenzi cyane; utuzu twabugenewe two mu nganda cyangwa imiterere yihariye y'imigozi bishobora gusaba Ingano ntoya zo gutumiza (MOQs) cyangwa bigasaba igihe cyo gutanga serivisi hagati y'ibyumweru 4 na 12. Guhitamo umucuruzi ufite aho atuye bishobora kugabanya cyane igihe cyo kudakora iyo bibaye ngombwa gusimbuza ibintu byihutirwa.

Uburyo bwa nyuma bwo guhitamo utuzu twangiza umuriro

Gushyira mu bikorwa uburyo bwo guhitamo buhamye byemeza ko ibintu byose bigenga amazi, ibidukikije, n'amategeko bigenzurwa neza mbere yo kurangiza itegeko ryo kugura.

Uburyo bwo guhitamo intambwe ku yindi

Imikorere yo guhitamo itangirana n'isesengura ryuzuye ry'ingaruka z'impanuka kugira ngo hamenyekane igipimo cy'amazi akenewe n'ubwoko bw'ibikoresho. Hanyuma, injeniyeri zigomba gukora ibarura ry'amazi, zigakoresha 10% kugeza kuri 15% by'umutekano mu bushobozi bwo kuvoma kugira ngo harebwe igihombo cy'uburiganya n'igabanuka ry'uburyo bwo kwangirika kw'imiyoboro uko igihe kigenda gihita. Iyo ibisabwa (GPM, PSI, n'icyitegererezo) bimaze gushyirwaho, amatsinda ashinzwe gutanga amasoko agabanya ubwoko bw'imiyoboro n'ibikoresho. Amaherezo, moderi zatoranijwe zihuzwa n'amahame ngenderwaho y'aho ziherereye ndetse n'ibyemezo bisabwa by'umuntu wa gatatu (urugero, FM / UL) mbere yo gusaba ibiciro by'abacuruzi.

Gukoresha imbonerahamwe y'ibyemezo

Kugira ngo isuzuma ribe ryemewe, abaguzi b'inganda bakunze gukoresha uburyo bwo gufata ibyemezo kugira ngo barebe neza imiyoboro y'umuriro ihanganye hashingiwe ku bipimo biremereye. Ubu buryo bwo gusesengura bukuraho ivangura rishingiye ku kwamamaza kandi bwibanda gusa ku bipimo by'imikorere n'agaciro k'ubuzima.

Ibintu by'ingenzi byakunzwe

• Imyanzuro y'ingenzi n'impamvu y'umunwa w'umuriro
• Ibisobanuro, kubahiriza amategeko, n'igenzura ry'ingaruka bikwiye kwemezwa mbere yo kwiyemeza
