Ukukhetha i-nozzle efanelekile kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuthembeka kwemishini yokuphepha emlilweni. Ngibonile ukuthi okokusebenza kwamadubuli omlilo kukuthinta kanjani ukusebenza kwawo, ukuqina, nokufaneleka kwezindawo ezithile. Ithusi nensimbi engagqwali yizinketho ezimbili ezidumile, ngayinye enezinzuzo ezihlukile. Kodwa yimuphi owufanelekela kangcono imibhobho yomlilo? Ake sihlole lo mbuzo ukuze sikusize wenze isinqumo unolwazi.

Okuthathwayo Okubalulekile

• Imibhobho yethusiyenza kahle ekudluliseni ukushisa futhi ilungele izindawo ezilawulwayo.
• Imibhobho yensimbi engagqwali ihamba phambili ngokuqina kanye nokumelana nokugqwala ezimweni ezinzima.
• Cabangela izindleko zesikhathi eside lapho ukhetha phakathi kwethusi nensimbi engagqwali.
• Ukuhlanza okuvamile nokuhlola kuthuthukisa ukusebenza kwazo zombili izinhlobo.
• Khetha ithusi lezinhlelo zokusebenza ezizwelayo izindleko kanye nensimbi engagqwali ezindaweni ezidinga kakhulu.

Ama-Nozzles Omlilo Wethusi

Ukusebenza Nezici

Ithusiidume ngokusebenza kwayo okushisayo okuhle kakhulu kanye nokumelana nokugqwala okuhloniphekile. Le ingxubevange yethusi-zinc inikeza machinability okuhle nokuqina. Ngephoyinti lokuncibilika elingu-927°C (1700°F) nokuminyana okungu-8.49 g/cm³, ithusi lihlinzeka ngobuqotho besakhiwo. Amandla ayo aqinile aphakathi kuka-338–469 MPa, okuqinisekisa ukusebenza okuthembekile ngaphansi kwengcindezi. I-conductivity ephezulu kagesi futhi ithuthukisa ukusebenza kahle kokusabalalisa ukushisa.

Izicelo Ezivamile Nezimboni

Imibhobho yethusi isetshenziswa kakhulu ekucimeni umlilo, ekufakeni amapayipi, nasezisetshenziswa zasolwandle lapho ukumelana nokugqwala kanye nendaba yokudlulisa ukushisa. Asebenza kahle kakhulu ezindaweni ezinokuchayeka kukhemikhali okumaphakathi. Ukusebenziseka kalula kwezinto kuyenza ilungele imiklamo yenozili yangokwezifiso edinga umumo oyinkimbinkimbi.

Izimbobo Zomlilo Zensimbi Engagqwali

Ukusebenza Nezici

Insimbi engagqwaliinamandla aphakeme okudonsa (621 MPa) kanye ne-elastic modulus (193 GPa). Okuqukethwe kwayo kwe-chromium (≥10.5%) kudala isendlalelo se-oxide esizilungisayo, sinikeza ukumelana nokugqwala okukhethekile. Ngephuzu lokuncibilika elingu-1510°C (2750°F) kanye nokwelulwa ngesikhathi sekhefu lika-70%, igcina ukuqina kwesakhiwo ngaphansi kwezimo ezimbi kakhulu.

Izicelo Ezivamile Nezimboni

Imibhobho yensimbi engagqwali ibusa ukucutshungulwa kwamakhemikhali, amapulatifomu angasogwini, kanye nezinhlelo zomlilo ezimbonini. Zikhethwa ezinhlelweni zokusebenza ezidinga ukuphila isikhathi eside nokunakekelwa okuncane ezindaweni ezigqwalile.

Izinto Ezibalulekile Zokuqhathanisa Zezinto Zombhobho

Ukuqina

Ukumelana ne-Abrasion

Insimbi engagqwali idlula ithusi ezindaweni ezihuqayo ngenxa yokuqina okuphezulu (150–200 HB vs 55–95 HB). Kumabhomu ethusi, sebenzisa amasistimu okuhlunga ukuze unciphise ukungena kwezinhlayiyana futhi uhlole ukuguga kwekota.

Ukusebenza Kokucindezela Okuphezulu

Insimbi engagqwali igcina ubuqotho ezingcindezini ezingaphezu kuka-300 psi, kuyilapho ithusi lingakhubazeka ngaphezu kuka-250 psi. Cabangela izilinganiso zokucindezela lapho ukhetha izinto zombhobho zamasistimu we-hydraulic.

Ukumelana Nokugqwala

Imikhawulo Yethusi

Imibhobho yethusi ithuthukisa i-patina ngokuhamba kwesikhathi lapho ibhekene nama-chloride noma ama-sulfide. Ezindaweni zasolwandle, i-dezincification ingenzeka phakathi neminyaka engu-2-3 ngaphandle kokumbozwa okufanele.

I-Stainless Steel Advantage

Thayipha 316 insimbi engagqwali imelana nesifutho sikasawoti amahora angu-1,000+ ngaphandle kokugqwala okubomvu. Ukwelashwa kwe-passivation kungakhuphula ukumelana nokugqwala ngo-30% ezindaweni ezine-asidi.

I-Thermal Conductivity

Ukuphumelela Kwethusi

I-Brass idlulisa ukushisa ngokushesha okungu-7x kunensimbi engagqwali, iyenze ifaneleke ezinhlelweni ezidinga ukulinganisa kwezinga lokushisa okusheshayo. Lesi sakhiwo sivimbela ukushisa okweqile kwasendaweni emisebenzini eqhubekayo yokucisha umlilo.

Imikhawulo Yensimbi Engagqwali

I-conductivity ephansi yokushisa yensimbi engenasici idinga ukuphathwa ngokucophelela kokushisa. Imibhobho ingase idinge amajakhethi okupholisa ekusetshenzisweni kokushisa okuphezulu okungaphezu kuka-400°C.

Ithiphu:Imibhobho yethusi ikhethwa ezinhlelweni zegwebu lapho ukulawulwa kwezinga lokushisa kuthinta izilinganiso zokunwetshwa.

Ukucatshangelwa Kwesisindo

Umthelela Wokusebenza

Imibhobho yethusi inesisindo esingu-15-20% ngaphezu kwensimbi engagqwali. Kumisebenzi ephathwa ngesandla, lo mehluko uthinta ukukhathala komsebenzisi:

• 1-1/4″ umlomo wethusi: 4.2 kg (9.25 lbs)
• Insimbi engagqwali okulingana: 3.5 kg (7.7 lbs)

Ukuhlaziywa Kwezindleko

Izindleko Zokuqala

Imibhobho yethusi ibiza kancane ngo-20-30% ekuqaleni. Amabanga amanani ajwayelekile:

• Ithusi: $150–$300
• Insimbi engagqwali: $250–$600

Izindleko Zomjikelezo Wokuphila

Insimbi engagqwali inikeza i-ROI engcono ngaphezu kweminyaka eyi-10+:

Amathiphu Okunakekela Nokuphila

I-Brass Nozzle Care

Iphrothokholi Yesondlo

1. Ukuhlanza nyanga zonke nge-pH-neutral detergent
2. Ukuhlolwa kwe-dezincification yonyaka
3. Ukuvuselelwa kwe-lacquer ye-biennial

Ukunakekelwa Kwensimbi Engagqwali

Iphrothokholi Yesondlo

1. Ukwelashwa kwe-passivation yekota
2. I-torque yaminyaka yonke ihlola ukuxhumana okufakwe imicu
3. Ukuhlolwa kwe-hydrostatic yeminyaka engu-5

Imibhobho yethusi nensimbi engagqwali inezinjongo ezihlukile ezinhlelweni zokuvikela umlilo. I-Brass inikeza ukusebenza kahle kwezindleko nokusebenza okushisayo kwezindawo ezilawulwayo, kuyilapho insimbi engagqwali inikeza ukuqina okungenakuqhathaniswa ezimeni ezinzima. Ukukhetha kwakho kufanele kuhambisane nezidingo zokusebenza, izici zemvelo, kanye nezinjongo zezindleko zomjikelezo wokuphila.

Imibuzo Evame Ukubuzwa

Yini engcono kakhulu imibhobho yethusi?

I-Brass idlula zonke ezinhlelweni ezingazweli izindleko ezinamazinga okushisa amaphakathi kanye nokuchayeka kumakhemikhali. Ilungele izinhlelo zomlilo zikamasipala nezakhiwo zezentengiselwano.

Kungani ukhetha insimbi engagqwali ezindaweni zasolwandle?

Insimbi engagqwali imelana nokugqwala kwamanzi anosawoti ngo-8–10x ubude kunethusi. Uhlobo 316SS luyimpoqo kwizicelo zasolwandle nge-NFPA 1962 ngayinye.

Kufanele kushintshwe kangaki ama-nozzle?

I-Brass: iminyaka engu-5-7
Insimbi engagqwali: 15+ iminyaka
Yenza ukuhlolwa kwaminyaka yonke ukuze kutholwe isikhathi sokushintshwa.

Ingabe ithusi lingakwazi ukuphatha amagwebu agxilile?

Yebo, kodwa gwema amagwebu amelana notshwala aqukethe ama-polymer - lawa asheshisa ukwenziwa kwe-dezincification. Sebenzisa insimbi engagqwali ezinhlelweni ze-AR-AFFF.

Ingabe impahla ye-nozzle iyawathinta amazinga okugeleza?

Inketho yezinto ezibonakalayo inomthelela emazingeni okuguguleka kodwa hhayi izici zokugeleza kokuqala. I-nozzle engu-1.5″ yethusi nokulingana okungenasici kuzoba nezilinganiso ezifanayo ze-GPM uma zintsha.
