Yini Okufanele Uyibheke Lapho Ukhetha I-Nozzle Eqhumayo?

Ukukhetha i-blast nozzle kuyisinqumo esibalulekile ngaphambi kokuthi uqale ukusebenza abezindaba. Ngokusobala udinga ukwazi mayelana ne-compressor yakho yomoya namandla we-nozzle ukuze umelane nomthelela ovela ezihlokweni ezicindezelwe eziphuma ngaphansi kwengcindezi. Ububanzi be-nozzle bore obunembile buzonquma umthamo wakho ophoqelelwe kanye nomthelela.

Ngemuva kokugqoka okuvamile lapho umlomo we-nozzle ukhuphuka, usayizi we-orifice yawo uzophindeka kane kodwa amandla omoya azoba sengozini futhi imidiya eyengeziwe izokhishwa.

Kukhona Izimo Ezimbili Zokuqhumisa Nozzle Okubalulekile ongakhetha Kuzo:

I-Sight Bore:Idala amandla afanayo acindezelayo ukusuka emlonyeni ukuya phezulu.

Uhlobo lwe-Venturi:Kuwumbhobho onxephezela ukulahlekelwa ingcindezi. Incane ukusuka ku-ejection ukunikeza ingcindezi egcwele uma iphansi ukusuka ku-compressor.

Ukuze uthole uhlobo lombhobho olungcono kakhulu, khomba ingcindezi yenozzle (PSI) okudingeka uyigcine ukuze uqhume ngendlela ekhiqizayo kanye nevolumu yomoya i-compressor oyihlinzeka ngomzuzu (CFM). Kodwa ukuze ulondoloze usayizi wombhobho, ukukhethwa kohlobo olwakhiwe kahle kungahamba isikhathi eside njengoba ukuhuzuka okuvela kumbhobho wekhwalithi ephansi kuzogqoka ulayini wangaphakathi futhi kulahlekelwe ingcindezi yevolumu ebalulekile. Uma ingcindezi isilahlekile, uthola amandla okucindezela anganele kanye nomphumela ongemuhle. Ngokufanelekile, ukugcinwa kwengcindezi kuyadingeka phakathi kwe-hose ne-compressor.

Yini Eyehlula Ingcindezi?

Ukuguga okuvamile okuvela ekukhuhleni kwabezindaba okunweba indawo ephuma emlonyeni ngaphakathi.

Ukuma okungajwayelekile noma ukugoba ku-nozzle.

Ukushintsha isiqondiso se-nozzle.

Izingxenye ezixhunywe ngokukhululekile ku-nozzle ezivela ku-compressor.

Ukuvuza emalungeni noma ekuxhumaneni okungalungile.

Isingathwa kanjani Le nkinga?

Hlola izingxenye zakho isikhathi ngasinye ngaphambi kokuzisebenzisa.

Qinisekisa ukuthi zifakwe ngokuqinile.

Bheka ukuvuza emalungeni.

Ngaso sonke isikhathi ukhetha ukusebenzisa umlomo wombhobho uqonde kunokugotshwa.

Khetha i-nozzle yekhwalithi enhle.

Faka esikhundleni imbobo ngesikhathi uma isigugile.

Iphethini yokuqhuma enkulu izodinga ukunyuswa kusayizi wenozzle futhi. Kusho ukuthi i-nozzle inkulu, iphethini yokuqhuma kufanele ibe nkulu. Uma kukhona ukucindezela okwanele futhi umlomo wombhobho umncane, uzokhiqiza umfudlana oqinile kanye nephethini yokuqhuma okugxilile phezu komthelela. Ku-Venturi, kukhona ukuhlangana lapho kungena kanye nokwehlukana lapho uphuma khona okugcina kuphethini enkulu yokuqhuma kanye nokusabalalisa izinhlayiyana ezifanayo. 

Ukuze uthole isivinini esikhulu sokuphuma, imibhobho yentamo ende ingashintshwa. Bakhiqiza iphethini yokuqhuma okukhulu kanye namazinga aphezulu okukhiqiza. Ngaphezu kwalokho, ingaphakathi le-nozzle libaluleke ngokufanayo ukunikeza imiphumela ehlala isikhathi eside.

Ingxenye ebaluleke kakhulu: Umbhobho ujwayele ukudabuka lapho ukungqubuzana kuhlikihla izinhlayiya ezicindezelwe emgudwini wawo. Ukunciphisa lokhu kuhlupheka, ukucatshangelwa okufanelekile ukwazi ukuthi i-nozzle yenziwe ngani. Ulwelwesi olungaphakathi lwebhore kufanele lwenziwe ngezinto eziqinile ukuze lukwazi ukumelana nokungqubuzana isikhathi eside. Ngokuyisisekelo imibhobho yenziwe nge-carbide efika ngezinhlobonhlobo ezi-3 okungukuthi i-tungsten carbide, i-silicon carbide ne-boron carbide, zonke ezishibhile kodwa ezinezinga elihlukile lokumelana nomthelela. Kodwa ngokumelana nokushaqeka okukhulu, ungakhetha i-carbide ehlanganisiwe enenani eliphezulu kodwa ukukhuthazela komthelela kukhulu. Njengoba iqinile, izinto ezinjalo nazo zidinga ukuphathwa ngokucophelela funa i-casing yangaphakathi izoqhekeka. Ezinye izinhlobo ezifana ne-boron carbide ezilukhuni kakhulu zinokuqina okungaphezu kwesilinganiso zingahlala izikhathi ezifika kweziyi-10 kune-tungsten carbide. I-composite carbide inzima nakakhulu.

Ngomqondo ojwayelekile, ukukhethwa kwe-abrasive kanye nohlobo lokusebenza kungamaphuzu abalulekile ukuze unqume ukuthi yimuphi umlomo wombhobho ozofanela abezindaba nakuba ngaphambi kokuyofuna umlomo owomile, zama umhwamuko.ukuqhuma kwe-abrasive esiza imibhobho yakho ukuthi ihlale izikhathi ezi-3 kunezomile. Njengoba umlomo wombhobho ungashibhile ukuwushintsha, ukuqhuma okumanzi kungakhethwa ngenxa yenzuzo yawo ngaphezu kwemibhobho eyomile. Ku-blaster emanzi, kukhona ukugeleza kwamanzi okugcoba okugwema ukungqubuzana okukhulu phakathi kwemidiya kanye nokokusebenza kwe-nozzle, ngakho-ke kwenza impilo ye-nozzle ibe yinde.
