INDLELA YOKUKHETHA

INOZZLE EYI-BRASIVE BLAST

Ukuba nombhobho wokuqhuma ofanele osayizi olungile wemishini yokuqhuma kanye nokusetshenziswa kungakhuphula kakhulu umkhiqizo wakho wokuqhuma kanye nesivinini.

Iphethini yokuqhuma iyadingeka

Iphethini yokuqhuma inqunywa ngesimo sokubhoboza kwe-nozzle.

Imibhobho ebhobozayo eqondile yenza iphethini yokuqhuma eqinile elungele ukusetshenziswa kwendawo noma ukusetshenziswa kwekhabhinethi yokuqhuma futhi ingcono kakhulu ekuhlanzeni izingxenye, ukubunjwa komthungo we-weld, umsebenzi wamatshe, ama-handrails njll.

I-Venturi bore nozzles idala iphethini yokuqhuma ebanzi futhi ingakhuphula isivinini esibi ngo-100%. Imibhobho emide ye-venturi ingakhuphula ukukhiqiza kufika ku-40% futhi inciphise ukusetshenziswa kwe-abrasive futhi kufike ku-40% uma kuqhathaniswa nemibhobho ebhobozayo eqondile.

Ngenozi ye-Double Venturi, umoya womkhathi udonswa ngezimbobo endaweni yokucindezela okuphansi, unwebe ukugeleza komoya ukuze ukhiqize iphethini yokuqhuma ebanzi.

Blast Nozzle Shape

Ukuma kwe-Blast Nozzle kunquma iphethini yokuqhuma nomthelela. Imbobo ebhobozayo eqondile ikhiqiza iphethini yokuqhuma emincane, egxilile kumthelela.

Umbhobho omude we-venturi ukhiqiza iphethini enkulu yokuqhuma kanye nokusabalalisa kwezinhlayiyana okufanayo kunombobo ojwayelekile.

Embobeni ye-Venturi ephindwe kabili, umoya womkhathi udonswa ngezimbobo endaweni yokucindezela okuphansi, unwebe ukugeleza komoya ukuze ukhiqize iphethini yokuqhuma ebanzi.

Imibhobho emide kakhulu isheshisa izinhlayiya ngebanga elide, ifinyelela isivinini sokuphuma esiphezulu, ivumela i-blaster ukuthi ime ngokuqhubekayo ukusuka endaweni eqhunyiswayo, futhi ikhiqize iphethini yokuqhuma okukhulu kanye namazinga aphezulu okukhiqiza.

Blast Nozzle Material

Izinto eziyinhloko ekukhetheni okubalulekile okubhoboza umlomo wombhobho ukuqina, ukuhuga okusetshenzisiwe, ukumelana nomthelela, kanye nentengo.

Imibhobho ye-Aluminium oxide “Alumina” ishibhe kunezinye izinto futhi ingasetshenziswa lapho izindleko ziyisici esiyinhloko futhi ukuqina kungabalulekile kangako.

Imibhobho ye-Tungsten Carbide ayihlali isikhathi eside kodwa ishibhile futhi imelana nomthelela.

Imibhobho ye-Silicon Carbide ayihlali isikhathi eside kodwa ilula futhi ibangela ubunzima obuncane bokusebenza.

Imibhobho ye-Boron Carbide imelana kancane kodwa iqinile kakhulu futhi ihlala isikhathi eside ngokuphindwe kashumi kune-Tungsten Carbide futhi yinde ngokuphindwe kathathu kune-Silicon Carbide.

Blast Nozzle Usayizi

Uma uphinda kabili ububanzi be-orifice, uphinda kabili usayizi we-orifice kanye nevolumu yomoya kanye ne-abrasive engadlula ku-nozzle. Uma umlomo wombhobho wesanti mkhulu kakhulu, isivinini somoya kanye nengxube ehubhukayo siphansi kakhulu futhi ayisebenzi ekuqhumeni kokukhiqiza. Uma umbhobho wokuqhuma kwesihlabathi umncane kakhulu, wehlisa isivinini sokuqhumisa kahle.

Ukuze uthole umbhobho wakho okhiqiza kahle, thola ukuthi iyiphi ingcindezi yenozzle (PSI) okudingeka uyigcine ukuze uqhume ngendlela ekhiqizayo, nokuthi ingakanani ivolumu yomoya i-compressor yakho etholakalayo enganikeza ngomzuzu (CFM), bese ubheka ishadi esigabeni esilandelayo ukuze uthole usayizi wembobo yombhobho ohlangabezana naleyo mingcele.

Ukunikezwa Komoya

Okokugcina, ukutholakala komoya kuyisici esibalulekile ekuqhumeni. Ukuphakama kwevolumu yomoya ocindezelweyo, kuyanda ukucindezela okukhiqizwa ku-nozzle. Yandisa isivinini sezinhlayiya ezilumayo, ivumela ukusetshenziswa kwembobo embobhozayo enkulu futhi inikeze iphethini yesikhonkwane ejulile Umuntu kufanele akhethe usayizi nohlobo lombhobho kuye ngokuphuma kwe-compressor, izici ezingaphezulu kanye nemininingwane yohlelo lokusebenza. Bheka ithebula elingezansi ukuze ukhethe umbhobho olungile ukuze ulondoloze umfutho womoya odingekayo ku-nozzle ngokusekelwe ekunikezeni komoya okutholakalayo.

Kodwa-ke, kubalulekile ukuthola indawo emnandi elungile njengoba ngale kwezinga elithile, izinga eliphezulu lokugwaza alinyusi ukukhiqiza futhi umlomo wombhobho wosayizi omkhulu ukhuphula imfucuza.

Izindlela Zokwandisa Impilo Yesevisi Ye-Nozzle

1. Gwema ukuwisa noma ukushaya imilomo.

2. Use imibandela yokukhetha engenhla ukuze ukhethe umbhobho ofanele wohlelo lwakho lokusebenza kanye ne-abrasive.

3. Hlola futhi ufake esikhundleni, ngokudingekayo, i-gasket, noma iwasha yombhobho noma isibambi somlomo ukuze usize ukuvimbela ukungena komphimbo ukuthi ungaqhumi.

4. Hlola bese Ushintsha Imilomo. Kungakanani ukugqokwa okukhulu kakhulu? Nazi izivivinyo ezintathu ezilula:

a. Faka i-drill bit yosayizi efana nebhore yangempela yomlomo. Uma kukhona i-slop, sekuyisikhathi sokuyishintsha. Ukugqokwa kweNozzle kusho ukuncipha kwengcindezi. Ukulahlekelwa yingcindezi kusho ukulahleka kokukhiqiza, kukhona ukulahleka kokukhiqiza okungu-1-1/2% kuwo wonke amaphawundi omfutho womoya olahlekile.

b. Bamba umlomo ovulekile uye ekukhanyeni bese ubheka phansi kwesibhobo. Noma imuphi umphumela wekhasi elinyakazayo noma elolintshi ngaphakathi kwe-carbide liner izodala isiphithiphithi sangaphakathi esinciphisa isivinini esibi. Uma ubona noma yikuphi ukugqoka okungalingani noma ukwehla kwengcindezi, sekuyisikhathi sokushintsha.

c. Bheka ingaphandle lombhobho, futhi. Izinto ezisetshenziselwa ukwakha ama-nozzles ziqinile, kodwa zingaba brittle. Izinto zokugqoka ze-Nozzle ziklanyelwe ukusiza ukuvikela amalayini aphuka emonakalweni womthelela. Uma ibhantshi liqhekekile noma liboshiwe, kungenzeka ukuthi i-liner nayo iphukile. Uma i-liner iphukile, ngisho nokuqhekeka kwezinwele, i-nozzle kufanele ishintshwe ngokushesha. Akuphephile ukusebenzisa umlomo wombhobho oqhekekile. Khumbula ukuthi wonke ama-nozzles azoguga ekugcineni. Gcina izinsiza zama-backup nozzles esandleni ukuze unciphise isikhathi sokuphumula.

Ukuze uthole imininingwane eyengeziwe mayelana nama-nozzles ethu, chofoza iwebhusayithi engezansi, futhi wamukelekile ukusithinta nganoma yimiphi imibuzo.
