Ingabe uyazi ngempela i-blast venturi nozzle? Masiyihlole!

- Qonda i-venturi nozzle kusuka ezicini ezintathu

I-Abrasive Blasting, njengenqubo yokuqedela indawo evame ukubandakanya ukusetshenziswa kwe-compressor yomoya kanye nomshini oqhumisayo, ukufafaza izinhlayiya ezilimazayo endaweni edingekayo ukuze ibe bushelelezi noma ibe nzima nakakhulu.

I-nozzle, njengento ebalulekile yokuqhunyiswa, ithuthukiswe ngokuvumelana nezidingo zezikhathi. Kwakukhona imibhobho ebhobokileyo eqondile kuphela maphakathi nawo-1950. Kodwa-ke, oqhumisayo wathola i-drawback yazo ngokuguga nokuguguleka ngaphakathi. Futhi ngaleso sikhathi, iphethini yokuqhuma esebenza kahle, i-venturi nozzle, ivele. Ngakho-ke yini i-venturi nozzles? Ake sikubheke ngokuningiliziwe.

Isakhiwo se-Venturi Nozzle

Ngokubukeka, i-venturi nozzle ihlukaniswe izigaba ezintathu. Okokuqala, iqala nge-converging inlet ende ecijile, ilandelwe yisigaba esifushane esiyisicaba esiqondile, bese iba nomkhawulo omude ophambukayo oba banzi uma ufinyelela phezulu eduze nendawo yokuphuma emlonyeni. Umklamo onjalo usiza ukwandisa ukusebenza kahle komsebenzi ngama-70%, futhi lokhu kufinyelelwa kanjani?

Umoya kanye ne-abrasive kungena ku-nozzle nge-converging inlet ende bese kugelezela esigabeni esifushane esiqondile kuyilapho ingcindezi iyancipha ngaleso sikhathi, okuholela kumehluko wengcindezi phakathi kwangaphakathi nangaphandle. Lo mehluko wengcindezi unikeza amandla angaphandle ezinhlayiya ezilumayo. Lapho i-abrasive ishiya umlomo wombhobho, ijubane liphakeme kabili kunelo lombobo oqondile. Ngakho ubuso buba buhlanzeke ngokuphumelelayo.

Izinhlobo ze-Venturi Nozzle

I-venturi blasting nozzle inezigaba ezihlukahlukene ezihlukaniswa ngama-engeli ahlukene. Isibonelo, ngokombono we-inlet, ihlukaniswe ibe yi-single-inlet kanye ne-double-inlets. Ngokuvamile ihlukaniswe nge-boron carbide, i-silicon carbide, ne-tungsten carbide ezintweni ze-liner. Ngaphezu kwalokho, uhlobo lwentambo luhlukaniswe kancane lwaba intambo eqinile kanye nentambo encane.

1.Kuhlukaniswa ngokungenisa

1.1 Imbobo ye-venturi ye-inlet eyodwa

Umbhobho we-venturi we-inlet eyodwa, landela i-Venturi Effect evamile, kusho ukuthi inendlela eyodwa kuphela edonsa umoya kanye ne-abrasive ukuze igeleze engxenyeni eyisicaba eqondile.

1.2 Imibhobho ye-venturi efakwa kabili

Njengoba kukhonjisiwe emfanekisweni ongenhla, inezimbobo ezimbili ezixhunywe negebe phakathi kwazo. Kunezimbobo ezincane eziyisishiyagalombili ezizungeze igebe ukusiza ukudonsa umoya ozungezile ku-nozzle, okwenza umoya okhishwe ube mkhulu kunomoya ocindezelwe odonswe ku-nozzle, ngaleyo ndlela isivinini sokugwaza siyathuthukiswa okuholela ekuhlanzeni kwendawo esebenza kahle kakhulu.

2. Ihlukaniswa ngezinto ze-liner

Izinto ezintathu ezaziwa kakhulu ezisetshenziswa namuhla ukuqhuma imibhobho yi-boron carbide, i-silicon carbide, ne-tungsten carbide.

2.1 I-Boron carbide venturi nozzle

I-Boron carbide nozzle ifaka ubulukhuni obuphezulu, ukugqokwa okuhle kakhulu, nokumelana nokuhuzuka. Kusukela ekubukeni, ukukhanya okuncane okubuthakathaka.

2.2 I-Silicon carbide venturi nozzle

I-silicon carbide nozzle inezici zamakhemikhali ezizinzile kanye nokumelana okuhle nokugqokwa. Ingaphezulu le-silicon carbide nozzle licishe lifane nele-boron carbide. Uma kuqhathaniswa ngokucophelela, i-silicon carbide imnyama ngokubonakala okuqinile. Inzuzo yayo ukuthi ingakwazi ukubumba kalula ibe yizimo ezihlukahlukene, futhi inenani eliphansi, kuyilapho ukumelana nokugqoka kuyi-1/3 kuya ku-1/2 yaleyo yokucindezela okushisayo.

2.3 I-tungsten carbide venturi nozzle

I-tungsten carbide nozzle ifaka ubulukhuni obuphezulu, ukumelana nokugqokwa okuhle, kanye nesakhiwo esizinzile esidinga ukulungiswa okuncane. Idili elisha lokukhethwa kwabaqhubi abaqhumisayo ngoba linokuqina okuhle kakhulu nokuguga lapho usebenzisa i-abrasive eqinile.

3. Ihlukaniswa ngentambo

Ingase ihlukaniswe ibe intambo eqinile nentambo ecolekile.

3.1 Uchungechunge Olumaholoholo 2”-4 1/2 U.N.C.

Intambo eqinile inegebe elikhulu phakathi kwentambo ngayinye, okusho ukuthi ifaneleka kakhulu
