Ngaba uyazi ngenene i-blast venturi nozzle? Masiyiphonononge!

--Qonda umlomo we-venturi kwimiba emithathu

I-Abrasive Blasting, njengenkqubo yokugqiba umphezulu ebandakanya ngokubanzi ukusetyenziswa kwe-compressor yomoya kunye nomatshini wokuqhushumba, kukutshiza amasuntswana abrasive kumphezulu ofunekayo ukuze ube mpuluswa okanye urhabaxa.

Umbhobho, njengento ebalulekileyo yokuqhushumba, iphuhliswe ngokweemfuno zamaxesha. Kwakukho imilomo ebhorekileyo kuphela phakathi kwiminyaka yoo-1950. Nangona kunjalo, umntu oqhubhisayo wafumanisa ukuba kukho ingxaki yokuguga kunye nokukhukuliseka ngaphakathi. Kwaye ngelo xesha, indlela esebenza ngakumbi yokuqhushumba, i-venturi nozzle, ivele. Ngoko ke yintoni imilomo ye-venturi? Makhe siyijonge ngokweenkcukacha.

Ulwakhiwo lwe-Venturi Nozzle

Ngokubhekiselele kwimbonakalo, i-venturi nozzle ihlukaniswe ngamacandelo amathathu. Okokuqala, iqala nge-converging inlet ende, ilandelwa licandelo elifutshane elithe tyaba elithe tye, emva koko libe nesiphelo esiphambukayo esiba banzi xa sifikelela kufutshane nombhobho wokuphuma. Uyilo olunjalo lunceda ukwandisa ukusebenza kakuhle kwe-70%, kwaye oku kufezekiswa njani?

Umoya kunye ne-abrasive zingena ku-nozzle nge-converging inlet ende kwaye emva koko uye kwindawo emfutshane ethe ngqo ngelixa uxinzelelo luyancipha ngelo xesha, nto leyo ekhokelela kumahluko woxinzelelo phakathi kwangaphakathi nangaphandle. Lo mahluko woxinzelelo unika amandla angaphandle kwiincinci ze-abrasive. Xa i-abrasive ishiya i-nozzle, isantya siphezulu kabini kunombhobho othe ngqo. Ngoko umphezulu uba ucoceke ngokufanelekileyo.

Iintlobo zeVenturi Nozzle

Umbhobho oqhumayo we-venturi uneendidi ezahlukeneyo ezihlelwe kwii-engile ezahlukeneyo. Ngokomzekelo, kwimbono yokungena, ihlukaniswe ibe yi-single-inlet kunye ne-double-inlets. Ngokuqhelekileyo yahlulwe kwi-boron carbide, i-silicon carbide, kunye ne-tungsten carbide kwizinto ze-liner. Ngaphezu koko, uhlobo lomsonto lucazululwe ngokurhabaxa lube yintambo erhabaxa kunye nentambo ecolekileyo.

1.Ihlelwa ngokwe-inlet

1.1 Umbhobho we-venturi one-inlet enye

Umbhobho we-venturi one-inlet enye, ulandela i-Venturi Effect eqhelekileyo, ithetha ukuba inendlela enye kuphela yokutsala umoya kunye ne-abrasive ukuba iphumele kwicandelo elithe tye.

1.2 Imilomo ye-venturi efakwa kabini

Njengoko kubonisiwe kulo mzobo ungentla, unemilomo emibini edityaniswe nesithuba phakathi kwabo. Kukho imingxunya emincinci esibhozo ejikeleze umsantsa ukwenza lula ukuzoba umoya ojikelezileyo kumlomo, nto leyo eyenza ukuba umoya ukhutshwe ube mkhulu kunomoya ocinezelweyo otsalwe ngumbhobho, ngoko ke isantya sokurhabula siyaphucuka sikhokelela kucociso olusebenzayo ngaphezulu.

2. Ihlelwe ngezixhobo zombane

Ezona zixhobo zithathu zidumileyo ezisetyenziswa namhlanje kuqhushumbo lwemilomo yi-boron carbide, isilicon carbide, kunye netungsten carbide.

2.1 Umbhobho weBoron carbide venturi

Umbhobho we-Boron carbide unobunzima obuphezulu, ukunxiba okugqwesileyo, kunye nokuxhathisa kwe-abrasion. Ukusuka kwimbonakalo, ukukhanya okuncinci okubuthathaka.

2.2 I-silicon carbide venturi nozzle

I-Silicon carbide nozzle ibonakaliswe kwiipropati ezizinzileyo zeekhemikhali kunye nokumelana nokunxiba kakuhle. Umphezulu we-silicon carbide nozzle uphantse ufane noboron carbide. Xa kuthelekiswa ngononophelo, i-silicon carbide imnyama kunye nokubonakala okunamandla. Inzuzo yayo kukuba inokubumba ngokulula kwiimilo ezahlukeneyo, kwaye inexabiso eliphantsi, ngelixa ukuxhathisa ukunxiba yi-1/3 ukuya ku-1/2 yale mibhobho yokucinezela eshushu.

2.3 Umbhobho weTungsten carbide venturi

Umbhobho we-tungsten carbide unobunzima obuphezulu, ukuxhathisa okulungileyo, kunye nesakhiwo esizinzile esidinga ukulungiswa okuncinci. Lukhetho olutsha lwesivumelwano kubaqhubi abaqhushumbayo kuba inokuqina okugqwesileyo kunye nokunxiba xa usebenzisa i-abrasive eqinile.

3. Ihlelwe ngokomsonto

Inokwahlulwa ngokurhabaxa ibe yimisonto erhabaxa kunye nentambo ecolekileyo.

3.1 Umsonto oQhelekileyo 2”-4 1/2 U.N.C.

Umsonto orhabaxa unomsantsa omkhulu phakathi komsonto ngamnye, oko kuthetha ukuba ufanelekile ngakumbiukuthwala ubunzima obukhulu kunye nempembelelo yempembelelo.

3.2 Umsonto Olungileyo 1-1/4” N.P.S.M

Umsonto ococekileyo uthetha umsantsa omncinci phakathi komsonto ngamnye, onokunciphisa ukuvuza kwamasuntswana.

4. Ihlelwa ngokobude

4.1 Umbhobho omde we-venturi

Njengoko igama libonisa, inde, isuka kwi-135mm ukuya kwi-230mm.

4.2 Umbhobho omfutshane we-venturi

Imfutshane, kwaye ubude ngokubanzi buqala kwi-81mm ukuya kwi-135mm.

Ukusetyenziswa kwe-nozzle venturi nozzle

Ukuqhushumba kweAbrasive yinkqubo yokugqiba umphezulu oquka ukugudisa okanye ukurhabaxa umphezulu, ukubumba umphezulu kunye nokususa ukungcola kumphezulu. Isetyenziswa kwiindawo ezininzi, njengokususa umhlwa kude nentsimbi engcolisekileyo, unyango lomphezulu welaphu lejean, kunye nokuthungwa kweglasi, njl.

Ukusebenza okuhlukeneyo kufuna iintlobo ezahlukeneyo zomlomo. Ukukhetha okufanelekileyo ngundoqo wokwandisa ukusebenza kakuhle.

Wamkelekile ukufumana i-ZZbetter yomgangatho ophezulu wemilomo ye-venturi.
