Imbali emfutshane kunye nophuhliso lweumzamoimilomo abrasive

Imbali emfutshane yeUkuqhunyiswa kwesantikwayeImilomo yeAbrasive 

Inkqubo yokuqhunyiswa kwesanti yaqala malunga ne-1870 ngendoda egama linguBenjamin Chew Tilghman, owabona ukunxitywa kwe-abrasive kwiifestile ezibethwa ngumoya. U-Tilghman uphinde waqaphela umphumo wokuba isanti enesantya esiphezulu inokuba nayo kwizinto eziqinileyo. Emva koko yenawaqala ukuyila umatshini onokuhambisa isanti ngesantya esikhawulezayo kunomoya - kwaye unokujolisa oku kuqukuqela kumlambo omncinci. Umbhobho oxhonywe kwiqonga elishukumayo, leyoingasetyenziselwa ukukhokela umlomo ngaphaya isubstrate.

Unokubona isakhiwo esilula somatshini we-sandblasting kwisithombe esingezantsi.

Umoya ocinezelekileyo wawunikezelwa ngombhobho. Umbhobho wokuqhushumbanikasIsanti isantya esifunekayo kuqhushumbo olunemveliso. Lo ibingumatshini wokuqala wokuqhunyiswa kwesanti, kunye nosetyenziso lokuqala lweumlomoibizwa ngokuba ngumlomo othe ngqo.

Ukude kube phakathi koo-1950, yonke imilomo yokuqhunyiswa kwesanti yayibhorekile. Ayenomnyango oguquguqukayo odityanisiweyo, icandelo lomqala elinxuseneyo, kunye negcweleyo-ubude bomgca othe tye kunye nokuphuma ngokuthe ngqo. Ngokuhamba kwexesha, abaqhubi boqhushumbo baye baqaphela ukuba njengoko ingaphakathi lale mibhobho liqala ukuguga kwaye likhukuliseka, kuye kwakho ipateni enkulu nesebenzayo yokuqhushumba. Olu qwalaselo lwakhokelela kuphuhliso loyilo lwe-venturi.

Ukuzalwakunye noPhuhlisoyoMlomo weVenturi

Ngaphandle kokuba umlomo weVenturi ungabonakali ekuqhunyisweni kwesanti kude kube ngoo-1950s, isiphumo seVenturi sasikhona kudala ngaphambili. Isiseko senzululwazi soyilo lwe-venturi saqala ngomsebenzi wengcali yezibalo kunye nefiziksi yaseSwitzerland uDaniel Bernoulli, owafumanisa ukuba ukuncitshiswa koxinzelelo lolwelo kubangele ukwanda kwesantya solwelo. Oku kubhaqiweyo wakupapasha kwincwadi yakheI-Hydrodynamicangowe-1738, yaza yabizwa ngokuba yi-Bernoulli’s Principle.

Kamva kwi-1700s, lo msebenzi wongezwa ngethiyori ehambelanayo evela kwisazi sefiziksi sase-Italiya u-Giovanni Battista Venturi. I-Venturi ikholelwa ngokufunyanwa kokunciphisa uxinzelelo lwamanzi olwenzeka xa ulwelo luhamba ngecandelo eliqingqiweyo lombhobho. Oku kwaziwa ngokuba yiVenturi Effect. 

IYilayoMlomo weVenturis

I-vUmbhobho we-enuri uyilwe in ungeno oluguquguqukayo olude, olunecandelo elifutshane elithe tyaba elithe tye, lilandelwa sisiphetho eside esiphambukayo esiba banzi njengoko ufikelela kwisiphelo sokuphuma somlomo.

Imilomo yeVenturi inokunyusa imveliso nge-70% ngenxa yepateni enkulu yokurhabula enesiphumo kunye nangenxa yokwanda kwesantya se-abrasive xa iphuma emlonyeni. Inyaniso,iisantya (isantya sokuphuma) se-abrasive ephumayo inokuba phantse iphindwe kabini kunombhobho othe ngqo, kwaye okuiamandla acoca umphezulu ngokukhawuleza.

Imibhobho ye-Venturi ephindwe kabini luhlobo oluthileumzamondikhuphe umlomo.

Ii-venturi kabiniisimbo (njengomzobo) kunokucingelwa njengemilomo emibini elandelelanayo enesithuba kunye nemingxuma phakathi ukuvumela ukufakwa komoya we-atmospheri kwindawo esezantsi yomlambo. Isiphelo sokuphuma sikwabanzi kuneumgangathoiphulo uqhushumboumlomo. Zombini izilungiso zenziwa ukwandisa ubungakanani bepateni yokuqhuma kunye nokunciphisa ilahleko yesantya se-abrasive.

I-BSTEC ibonelela ngomgangatho ophezulu womgangathoventuriimilomo kwaye kabiniumzamoimilomo, so ukuba ukwimarike ujonge ukuphucula ukusebenza kwakho,ungaqhagamshelana nathi ngeenkcukacha ezithe vetshe.
