In DephUukuqonda kweSkanye nokuqhunyiswafrom Manje

Asivamile ukubhekisela egameni elithi sandblasting ekuphileni kwansuku zonke, kodwa lisetshenziswa kuzo zonke izici zempilo yethu. Ngakhouyazi ngempela ukuthi kuyinii-sandblasting? Ukuze ujwayelane nayo, isingeniso esilandelayo singaba usizo kuwe. 

I-Abrasive Blasting

Brief Isingeniso

I-Abrasive behlala njalo inqubo yeukuqedwa kwendawongokuqhubaabezindabakwea isivinini esikhulu sibheke kuyo. Kuyashesha futhielulaindlela yokususaukungcola okungaphezulukusuka ensimbi, irabha,noma ipulasitiki.

Ukuqhuma kwe-abrasive kuvamise ukwenziwa ezindaweni ezivaliwe ezifana naleziamagumbi okuqhunyiswa noma amakhabethe, noma ezindaweni ezivulekile njengasesikebheni, esakhiweni, nasebhulohweni, njll.

Izinhlobo

Behlala njalo inezinhlobo eziningi ezijwayelekile ngokuya ngemidiya ehlukene:

 Ukuqhunyiswa kwesihlabathi

 Ukuqhunyiswa kwe-abrasive okumanzi

 Vukuqhuma kwe-apor

 Ukuqhunyiswa kobuhlalu

 Ukuqhuma kweqhwa

Ukuqhuma kunezinhlelo ezintathu zokulethwa kwemidiya:

 Ukuqhuma komoya (pneumatic)

 Isondo likaMechanical (ukuqhuma okungenamoya)

 Ukuqhuma kwe-Hydro (amanzi ampontshiwe)

Ukuqhunyiswa kwesihlabathi

Isingeniso esifushane

Njengeuhlobo yokuqhuma okulimazayo, i-sandblasting inqubo yokwelapha okungaphezulu evame ukuqukatha i-compressor yomoya, izinhlayiya ezilimazayo, kanye nombhobho wokufafaza izinhlayiya ezilimazayo ngaphansi kokugeleza komoya ngaphansi kwengcindezi ephezulu. Ibizwa ngokuthi i-sandblasting ngoba iqhuma ngezinhlayiya zesihlabathi. Lapho izinhlayiya zesihlabathi zifuthwa phezulu, zakha okufunayo.

Umlando we-sandblasting nama-nozzles

Ukuqhunyiswa kwesihlabathi kuyinto evamileokwenzeka kuimvelo, hhayi okusungulwe ngumuntu. Ngakho-ke, uma sifunayazilapho i-sandblasting ibonakala, ingalandelwa emuva ekuqaleni kwe-ukuzalwazomhlaba. Uthuli, isihlabathi,noma inhlayiyakuqhunyiswengomoya unamandla okuushintshoubuso benye into emthelela. Thatha isibonelo empilweni yethu, ukuguguleka komoya.

Ngo-1980, indoda okuthiwa uBenjaminHlanga uTilghmanwathola lesi senzakalo semvelo lapho ebona amafasitela ayenesihlabathi esipheshulwa ngumoya. Ngaphezu kwalokho, waklama umshini okwazi ukuqhubeza izinhlayiya zesihlabathi ngomoya ocindezelwe ukuba ziye phezulu kwezinto. Umshini wokuqala wokuqhumisa isihlabathi obizwa ngokuthi i-straight bore nozzle.

Isazi sezibalo saseSwitzerland kanye nesazi sefiziksi uDaniel Bernoulli sathola ukuthi tUmehluko wengcindezi yomoya ungakhuphula isivinini sokugeleza kwe-abrasive, eyaziwa ngokuthi uBernoulli’s Isimiso.

Khona-ke ngawo-1700, lesi simiso sengezwe isazi seFiziksi sase-Italy u-Giovanni Battista Venturi. Kuze kube ngawo-1950, i-Vngenaama-nozzles avele naphezu kokuthi umphumela we-Venturi wawukhona kudala ngaphambili.

Izitayela Ezivamile Zokuqhumisa Isihlabathi Nozzles

Iminyaka eminingi, izinhlobo ezahlukeneama-nozzles akhiqizwa ngokwesidingos. Ngobaisibonelo, iI-venturi nozzle iyisinqumo esingcono kakhulu sokuqhunyiswa kwesihlabathi okusebenzayo. Iukuqhunyiswa kwamapayipi angaphakathiumlomo wombhobhoisikakhulukazi esetshenziswacacileubusongaphakathiipayipi.I-bI-anana nozzle isetshenziswa kakhulu ukuhlanza izindawo eziwumngcingo noma okunzima ukuzibamba ngombhobho ojwayelekiles.

I-Venturi Nozzle: Imibhobho ye-Venturi ifaka iphethini yokuqhuma ebanzi ekhuthaza ukuqhuma ngokuphumelelayo. Isimiso siwukuthi ukuncipha komfutho woketshezi kuholela ekwandeni koketshezi’s isivinini.

Umbhobho wokungeniswa kwamanzi: Kubonakala ngoketshezi oluxuba izinhlayiya eziqhumayo namanzi okwelashwa kwendawo. Uma kuqhathaniswa namanye ama-nozzles, inobungane empilweni yokucindezela uthuli.

Umbhobho Wokuqhuma Kwepayipi Yangaphakathi: Isetshenziselwa ukuhlanza udonga lwangaphakathi lwepayipi eliqhuma ngephethini yekhoni.Izinhlobo ezahlukene ze-nozzles ziyatholakalaokweamadayimitha angaphakathi wepayipi ahlukene. Ngezinye izikhathi amathuluzi engeziwe ayadingeka, njenge amasethi wamakholomu, inqola ephakathi nendawo, kanye nekalishi elijikelezayo eliqhumayo.

Umbhobho Ogobile Ubhanana:Iyo’ i-engeli egobile ivumela ukufinyelela kokuqhunyiswa kwesihlabathi ezindaweni eziqinile noma ezilingana kahle. Itkuyisinqumo esihle ezindaweni eziwumngcingo noma okunzima ukubhekana nazoejwayelekileimibhobho
