Intangiriro

Mu kuzimya umuriro mu nganda, umunwa w'amazi si ikintu gito cyoroshye gukoresha ahubwo ni ahantu ho kugenzura aho amazi agera, aho amazi anyura, aho amazi anyura, n'aho anyura. Guhitamo neza bigira ingaruka ku buryo amazi cyangwa ifuro byinjira mu bushyuhe, bikarinda ibikoresho, kandi bigakomeza gukoreshwa n'ababikora mu bihe bigoye. Iyi nkuru isobanura ibintu by'ingenzi bituma amazi ahitamo, harimo ubwoko bw'ibyago, ibisabwa ku muvuduko n'aho amazi anyura, imiterere y'amazi, ibyo ifuro rikenera gukoreshwa, n'aho rigarukira. Mu mpera, abasomyi bazaba bafite uburyo bwo guhuza umunwa w'amazi n'ibyago byihariye by'inganda n'imiterere y'imikorere, bigatuma ibisobanuro bya tekiniki biri mu bice biri imbere byoroha kubisuzuma no kubikoresha.

Impamvu guhitamo utuzu dukoresha umuriro ari ingenzi mu nganda

Kuzimya inkongi mu nganda bisaba ubuhanga, ubwizerwe, no gusobanukirwa neza imiterere y'amazi.Guhitamo umunwa w'umurironi icyemezo cy'ibanze gigena mu buryo butaziguye imikorere myiza y'amazi, igipimo cy'ikoreshwa ry'ibikoresho, n'ubushobozi bwo guhangana n'ibibazo mu gihe cy'ibikorwa byo gukumira stress nyinshi.

Ingaruka ku mikorere yo gukumira no kurinda umutekano w'abakoresha

Akamaro k'ibanze k'umuyoboro w'amazi ni uguhindura amazi cyangwa ifuro umugezi w'ingirakamaro, ariko imiterere yawo igira ingaruka zikomeye ku mikorere myiza yo kuzimya umuriro ndetse no ku mutekano w'umukoresha. Ingano y'ibitonyanga n'aho amazi agera ni byo bigaragaza uburyo ikintu kizimya umuriro cyinjira mu nkingi z'ubushyuhe. Urugero, ibitonyanga bito byongera ubuso bwo kwinjiza ubushyuhe ariko bibura uburemere bwo kwinjira mu bushyuhe bufite umuvuduko mwinshi.

Ku rundi ruhande, umutekano w'umukoresha ugengwa cyane n'imbaraga z'umuvuduko w'amazi. Imbaraga z'umuvuduko w'amazi ku mugezi ukomeye zibarwa hakoreshejwe formula NR = 1.57 × d² × p, aho umutwe wa santimetero 1.25 ukorera kuri 50 PSI utanga ibiro bigera kuri 122 by'imbaraga z'umuvuduko. Kurenga urugero rw'imbaraga z'umukoresha umwe—ubusanzwe ibiro 60 kugeza kuri 75—bishobora gutera umunaniro wihuse, kubura uburyo bwo kugenzura amazi, no gukomereka bikomeye mu kazi.

Ibintu by'inkongi z'umuriro bigira ingaruka ku guhitamo utuzubu

Ibidukikije by'inganda bigaragaza imiterere y'impanuka zikomeye zirenze kure imiterere isanzwe y'inkongi z'umuriro mu mujyi. Inyubako nk'inganda zitunganya peteroli, ububiko bw'ibikoresho byinshi, n'inganda zitunganya imiti akenshi ziba zifite imiterere y'inkongi ifite igipimo gikabije cyo kurekura ubushyuhe (HRR). Inkongi y'amazi ikoreshwa mu nganda ishobora gutanga HRR irenga megawati 100 byoroshye, bigasaba ubushobozi bunini bwo gukonjesha no kunyura mu mazi menshi.

Mu gice gitunganya imiti, kuba hari imiyoboro ya gazi irimo umwuka mwinshi bishobora gusaba imiterere miremire yo kurinda igihu kugira ngo birinde itsinda ry’abatera imbere mu gihe batandukanya isoko y’ibikomoka kuri lisansi. Guhitamo umunwa ukwiye bisaba kugereranya imiterere yihariye y’imikorere y’ibikoresho n’ubushobozi bwabyo bwo kubitanga, kugira ngo ibikoresho bishobore guhangana n’ubushyuhe buteganijwe n’ibyago byihariye bya shimi biboneka aho bikorera.

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

Gushyira imiyoboro mu byiciro hakurikijwe uburyo ikora ni ingenzi cyane mu guhuza ibikoresho n'ibikorwa remezo by'amazi biriho muri icyo kigo. Ubuhanga bw'imbere bw'imiyoboro bugena uburyo amazi akorwa, yihuta, kandi agashyirwa mu gace karimo ibyago.

Imbobo yoroshye, Igihu, Galoni ihitamo, n'amanozo yikora

Ubusanzwe, amashami y’inganda azimya umuriro ahitamo hagati y’aho amazi anyura n’aho anyura mu kirere. Amasasu y’amazi anyura mu kirere atanga amazi menshi ku gipimo gito cy’umuvuduko ukoreshwa—akenshi akaba ari 50 PSI—agatanga ubushobozi bwo kugera ku kirere kinini, kwinjira cyane, no kwinjira mu kirere bike, ibi bikaba ari ingenzi cyane mu gukumira ihungabana ry’ubushyuhe.

Utuzu twa galoni duto, dushobora gukora imiterere kuva ku migezi igororotse kugeza ku miyoboro miremire irinda, tugabanyijemo galoni idahinduka, galoni ishobora gutoranywa, n'ubwoko bwikora. Utuzu twa galoni duto dushobora gutoranywa twemerera abakoresha guhindura umuvuduko w'amazi n'intoki (urugero: 95, 125, 150, cyangwa 200 GPM) mu gihe bakomeza gusohora umuvuduko uhoraho wa pompe. Utuzu twa galoni dukoresha uburyo bw'imbere bwo gusohora amazi kugira ngo dukomeze umuvuduko uhoraho wa pompe—ubusanzwe 75 cyangwa 100 PSI—mu rugero ruhindagurika rw'amazi, bigatuma amazi agera ku mugezi nubwo umuvuduko wa pompe waba uhindagurika mu bihe bigoye by'inganda.

Ibisobanuro by'ingenzi: Igipimo cy'umuvuduko, umuvuduko, kugera ku muvuduko, n'icyitegererezo

Gusuzuma imiterere y'ingenzi bireba ko umuyoboro w'amazi ukora neza mu gihe cy'aho amazi aherereye. Igipimo cy'amazi atemba (gipimirwa muri galoni ku munota cyangwa litiro ku munota) n'umuvuduko w'amashanyarazi ni byo bipimo by'ingenzi. Kutahuza hagati y'umuvuduko w'umuyoboro w'amazi n'umuvuduko w'umuyoboro w'amazi bizatera imbaraga zidashobora gucungwa cyangwa umuyoboro udafite imbaraga.

Uburyo bwo guhuza akantu ko gutwikira umuriro n'ibyago byo mu nganda no

Kugira ngo amazi akoreshwe neza, hashingiwe ku guhuza neza imiterere y’amazi asohoka n’ibyago byihariye bya shimi ndetse n’uburyo bwose bw’amazi bukoreshwa mu nganda. Amazi akoreshwa ni kimwe mu bigize urusobe rw’ibinyabuzima rugari rwo gukumira.

Ingaruka zo kugaruka ku buzima

Gushyira mu byiciro bitandukanye inkongi bisaba uburyo butandukanye bwo kuyikoresha n'ubushobozi bwo kuyikoresha. Ku birebana n'ingaruka z'amazi yo mu cyiciro cya B, umunwa w'umuriro ugomba gutanga ibisubizo by'ifuro neza. Nubwo iminwa isanzwe y'ifuro ishobora gukoresha ifuro ridafite umwuka hamwe n'ibipimo byo kwaguka hagati ya 3: 1 na 5: 1, iminwa yihariye yo gusohora umwuka akenshi irakenewe kugira ngo hagerwe ku bipimo bigera kuri 20: 1 ku gitambaro kinini kandi gikomeye cyo gukumira umwuka.

Mu gukemura ikibazo cy’inkongi z’amashanyarazi zo mu cyiciro cya C mu bigo bitanga amashanyarazi, imigezi ikomeye itera ibyago bikomeye byo gushorwa n’amashanyarazi. Ahubwo, hategetswe imiterere y’ibihu ifite atome nziza. Amabwiriza y’inganda muri rusange asaba ko intera iri hagati ya metero 10 n’ibikoresho bizima bifite amashanyarazi menshi mu gihe hakoreshejwe imiterere y’ibihu nibura 100 PSI kugira ngo amazi akomeze guhagarara, bityo bikarinda ko amashanyarazi agaruka ku mukoresha.

Ibintu bigize sisitemu: Imiterere y'umuyoboro w'amazi, ubushobozi bwa pompe, n'ibikoresho bya foam

gusimburana

Umuyoboro ugomba kuba ujyanye n'imiterere y'imiyoboro y'ikigo, ubushobozi bwo gupampa, na sisitemu yo gupima ifuro. Gutakaza ubwihisho mu miyoboro ni ikintu cy'ingenzi; urugero, gutemba kwa GPM 150 mu muyoboro wa santimetero 1.75 bitanga hafi PSI 30 kugeza kuri 35 yo gutakaza ubwihisho kuri metero 100.

Iyo ikigo gikoresha imiyoboro miremire (urugero, metero 300 cyangwa zirenga), umuyoboro muto wa 50 PSI ushobora kuba ngombwa kugira ngo habeho amazi ahagije adarenze urugero rw'umuvuduko ntarengwa w'ipompo yo gutwika umuriro iri aho hantu. Byongeye kandi, iyo ukoresha utumashini duto two gusohora ifuro, igipimo cy'umuyoboro kigomba kuba gihuye neza n'igipimo cy'umwarimu (urugero, umuyoboro wa 125 GPM uhujwe neza n'umuyoboro wa 125 GPM) kugira ngo hirindwe ko umuvuduko w'umugongo wangiza ingaruka za Venturi, ibyo bikaba byatera uruvange rw'ifuro ruto kandi rudakora neza.

Ibiciro by'iyubahirizwa ry'amategeko, kuramba, n'igihe cy'ubuzima

Itangwa ry'amasoko yaibikoresho byo kuzimya umuriro mu ngandaIrenze imikorere y’amazi mu bijyanye no kubahiriza amategeko, kuramba kw’ibidukikije, no gucunga umutungo igihe kirekire. Inzego z’inganda zishyira ibikoresho mu kaga gashobora kwangirika, ikirere gikabije, ndetse no gukoreshwa nabi cyane mu buryo bukabije.

Ibisabwa ku mahame ngenderwaho, ibizamini, n'ibyerekeye kwemeza aho hantu

Imiyoboro y'inkongi igomba kubahiriza amahame akomeye yo gukora no gukora kugira ngo ihamye ko yizewe mu gihe cy'impanuka. Muri Amerika ya Ruguru, NFPA 1964 (Standard for Spray Nozzles) igena imikorere ihamye. Kugira ngo igerweho, umuyoboro ugomba kwihanganira igeragezwa ry'umuvuduko wa hydrostatic wa 900 PSI nta kibazo cy'imiterere kandi ugahangana n'igeragezwa rya metero 1.8 ku buso bwa sima nta kibazo cy'imikorere yawo.

Byongeye kandi, inyubako nyinshi z'inganda, cyane cyane izifite ubwishingizi bwaibigo mpuzamahanga bicunga ibyago, bisaba ibikoresho byo gutwara ibyangombwa bya FM Global cyangwa urutonde rwa UL. Ibi byemezo bitanga igenzura ryigenga ry'uko umunwa uzakora neza ibisabwa byatangajwe mu gihe cy'inganda zigoye cyane, bityo bikaba byujuje ibisabwa mu igenzura ry'umutekano ndetse no mu bwishingizi.

Kubungabunga, Guhugura, n'Ikiguzi cyose cy'Ubutunzi

Igiciro cy'Ubucuruzi (TCO) gikubiyemo igiciro cya mbere cyo kugura, kubungabunga buri gihe, n'igihe cyo gukora kw'ibikoresho. Guhitamo ibikoresho bigira uruhare runini muri TCO. Aluminiyumu ikoze mu buryo bworoheje ni yo isanzwe ikoreshwa mu bijyanye n'imiterere yayo yoroheje, ariko mu bidukikije nk'inganda zitunganya ibyuma ku nkombe cyangwa inganda zikora imiti, umuringa uremereye cyangwa icyuma kidashonga bishobora gukenerwa kugira ngo hirindwe kwangirika vuba.

Ikiguzi cy'amahugurwa kigomba kandi gushyirwa muri TCO. Imashini zikora akazi gakomeye zikenera amahugurwa akomeye y'umukoresha kugira ngo asobanure imiterere y'amazi n'ingengo y'imari yo kubungabunga imashini zikora mu buryo bworoshye, mu gihe imashini zikora akazi gasanzwe zisaba gusanwa gake kandi zigatanga imikorere yoroshye cyane.

Gushyiraho uburyo busanzwe bwo gutanga amasoko bitanga umusaruro uhamye, umutekano, n'imikorere myiza mu matsinda y'ubutabazi bw'ibanze mu nganda. Uburyo bukoreshwa mu buryo bunoze bugabanya ibyago byo guhitamo ibikoresho bidashobora gukoreshwa cyangwa bishobora guteza akaga mu buryo bukabije.

Isuzuma n'Igenamigambi ry'Intambwe ku Ntambwe

Isuzuma rigomba gutangirira ku isuzuma ryimbitse ry’ibyago kugira ngo hamenyekane ingaruka z’inkongi z’umuriro (urugero: ibinyabutabire by’izuba, imyuka ishyushye, ivumbi rishobora gushya). Hanyuma, injeniyeri zigomba gukorakubara hifashishijwe hydraulichashingiwe ku mapompo azimya umuriro asanzwe n'umuvuduko w'imiyoboro ihagaze kugira ngo hamenyekane umuvuduko ntarengwa uboneka ku gasanduku k'imiyoboro ka kure cyane.

Iyo ibipimo bya hydraulic bimaze gushyirwaho, itsinda rishinzwe gutanga amasoko rigomba gushyira ku rutonde imiyoboro ikora muri izi mbibi—urugero, kuyungurura imiyoboro ya GPM 150 ikora kuri 75 PSI. Intambwe ya nyuma yo gushyira ku rutonde ikubiyemo isuzuma ryakozwe n'abagize itsinda ry'abasirikare. Gupima mu murima bituma abakora basuzuma imiterere y'umugozi w'icyuma, uburyo impeta yo guhitamo imiterere imeze neza, ndetse n'ubushobozi bwo gucunga imbaraga zo gukora iyo bambaye ibikoresho byuzuye byo kwirinda (PPE).

Ibipimo ngenderwaho by'ibyemezo bya nyuma ku mikorere, kubahiriza amategeko, n'ikiguzi

Umwanzuro wa nyuma ushingiye ku buryo bungana bwo gukora neza kw'amazi, kubahiriza amategeko, n'imbogamizi mu by'imari. Nubwo umuyoboro w'amazi wihuta ushobora gutanga uburyo bworoshye bwo gukoresha mu buryo budasanzwe hamwe n'igiciro cya mbere kiri hagati ya $800 na $1,500 kuri buri gikoresho, ushobora guteza ingorane zidasanzwe ku kigo gisaba cyane cyane gukonjesha vuba kandi ku bwinshi binyuze mu mpande zombi z'amazi zigenda neza za $300.

Abafata ibyemezo bagomba gushyira imbere guhuza na foam concentrates n'ibipimo byayo, kuko sisitemu zidahuye zishobora gutuma ibikoresho bihenze bitakora neza na gato. Amaherezo, guhitamoumunwa w'umuriro ukwiyebisaba gushyira imbere urwego rw'umutekano rw'umukoresha, kwemeza ko ibikoresho byatoranijwe bishobora gutanga igipimo cy'ingenzi gikenewe (urugero, 0.16 GPM kuri metero kare imwe ku nkongi z'umuriro zisanzwe) bitarenze ingano y'itsinda rishinzwe ubutabazi.

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
