Isethulo esifushane se-Straight Bore Nozzle

Njengoba sonke sazi, ukuqhuma kuyinqubo yokusebenzisa izinto eziqhumayo ezinomoya wesivinini esiphezulu ukuze kukhishwe ukhonkolo noma ibala ebusweni bomsebenzi. Kunezinhlobo eziningi zemibhobho yokuqhuma ukufeza le nqubo. Ziyi-nozzle eqondile, i-venturi bore nozzle, i-Venturi nozzle ephindwe kabili, nezinye izinhlobo ze-nozzle. Kulesi sihloko, i-nozzle ye-bore eqondile izokwethulwa kafushane.

Umlando

Umlando wemibhobho eqondile iqala ngendoda, u-Benjamin Chew Tilghman, owaqala ukuqhunyiswa kwesihlabathi cishe ngo-1870 lapho ebona ukuguga kwamafasitela okubangelwa ugwadule olupheshulwa ngumoya. U-Tilghman waqaphela ukuthi isihlabathi esinesivinini esikhulu singasebenza ezintweni eziqinile. Wabe eseqala ukuklama umshini okhipha isihlabathi ngesivinini esikhulu. Umshini ungagxilisa ukugeleza komoya emfudlaneni omncane futhi uphume komunye umkhawulo womfudlana. Ngemva kokuba umoya ocindezelweyo unikelwe ngombhobho, isihlabathi singathola isivinini esikhulu emoyeni ocindezelwe ukuze siqhume ngendlela ekhiqizayo. Lona bekuwumshini wokuqala wokuqhumisa isihlabathi, futhi umbhobho osetshenzisiwe wawubizwa ngokuthi i-straight bore nozzle.

Isakhiwo

Umbhobho oqondile wenziwa izingxenye ezimbili. Esinye isiqephu eside esine-tapered esihlangene sokugxilisa umoya; enye ingxenye eqondile eyisicaba yokukhulula umoya ocindezelweyo. Lapho umoya ocindezelweyo ufika ekugcineni okuhlangene okude, uyashesha ngezinto eziqhumayo. Ukuphela okuhlanganayo kuyisimo se-tapered. Njengoba umoya ungena, ukuphela kuhamba kancane. Umoya ocindezelweyo ukhiqize isivinini esikhulu nomthelela omkhulu esigabeni esiqondile esiyisicaba, esisetshenziswa ukuze kukhishwe izinto ezengeziwe endaweni.

Izinzuzo Nokubi

Uma kuqhathaniswa nezinye izinhlobo zemibhobho yokuqhuma, imibhobho ebhobokile eqondile inokwakheka okulula futhi kulula ukuwenza. Kodwa njenge-nozzle evamile kakhulu, inokushiyeka kwayo. Imibhobho ebhobozayo eqondile ayithuthukisiwe njengezinye izinhlobo zemibhobho, futhi uma isebenza, umoya ophuma kubhobo elibhobozayo ngeke ube nalowo mfutho ophezulu.

Izinhlelo zokusebenza

Imibhobho ebhobokileyo eqondile ivame ukusetshenziswa ekuqhumeni kokuqhuma kwamabala, ukubunjwa kwe-weld, neminye imisebenzi eyinkimbinkimbi. Zingasetshenziswa futhi ekuqhumeni nasekususeni izinto endaweni encane ngomfudlana omncane.

Uma ufuna ukufunda kabanzi mayelana nokuqhunyiswa kwe-abrasive, wamukelekile ukuthi usithinte ukuze uthole ulwazi olwengeziwe.
