INDLELA YOKUKHETHA

INOZZLE ENGABRASIVE BLAST

Ukuba noqhushumbo oluchanekileyo olulinganiswe ngokufanelekileyo kwisixhobo soqhushumbo kunye nesicelo kunokunyusa kakhulu imveliso yakho yokuqhushumba kunye nesantya.

Kufuneka ipateni yokuqhushumba

Ipateni yokuqhuma igqitywe yi-nozzle ye-bore shape.

Imilomo ebhobhozayo ethe tye yenza ipateni eqinileyo yokuqhushumba ilungele indawo yokuqhushumba okanye ukusetyenziswa kwekhabhathi yoqhushumbisi kwaye ilungele ukucoca iindawo, ukubunjwa komthungo we-weld, umsebenzi wamatye, iintsimbi zezandla njl.njl.

I-Venturi ibhore imilomo yenza ipateni yokuqhushumba ebanzi kwaye inokunyusa isantya sokurhabula ukuya kuthi ga kwi-100%. Imilomo emide ye-venturi inokunyusa imveliso ukuya kuthi ga kwi-40% kwaye yehlise ukusetyenziswa kwe-abrasive kunye nokuya kuthi ga kwi-40% xa kuthelekiswa nemilomo ebhorekileyo.

Ngombhobho we-Double Venturi, umoya we-atmospheri utsalwa kwimingxunya ukuya kwindawo yoxinzelelo oluphantsi, ukwandisa ukuhamba komoya ukuvelisa ipateni yokuqhushumba ebanzi.

Ukumila koMlomo wokuqhushumba

Ubume boMlomo weBlast bumisela ipateni yokuqhushumba kunye nesiphumo. Umbhobho wokubhoboza othe tye uvelisa ipateni emxinwa, egxininisiweyo yokuqhushumba kwimpembelelo.

Umbhobho omde we-venturi uvelisa ipateni enkulu yokuqhuma kunye nokusabalalisa kwamasuntswana afanayo kunombhobho oqhelekileyo.

Kwi-nozzle ye-Venturi ephindwe kabini, umoya we-atmospheric utsalwa kwimingxuma kwindawo yoxinzelelo oluphantsi, ukwandisa ukuhamba komoya ukuvelisa ipateni yokuqhuma okubanzi.

Imilomo emide eyongezelelekileyo ikhawulezisa amasuntswana kumgama omde, ifikelela kwisantya esiphezulu sokuphuma, ivumela iblaster ukuba ime ngasemva ukusuka kumphezulu oqhushumbayo, kwaye ivelise ipateni yokuqhushumba enkulu kunye namazinga aphezulu emveliso.

Ukuqhushumba kweMathiriyeli yoMlomo

Ezona zinto ziphambili ekukhetheni eyona nto ifanelekileyo yokuthwala umlomo kukuqina, ukurhawuzelelwa okusetyenzisiweyo, ukuxhathisa impembelelo, kunye nexabiso.

Imilomo ye-aluminiyam oxide "i-Alumina" inexabiso eliphantsi kunezinye izinto kwaye inokusetyenziswa apho ixabiso liyeyona nto iphambili kwaye ukuqina kubaluleke kakhulu.

Imilomo yeTungsten Carbide ayihlali ixesha elide kodwa inexabiso eliphantsi kwaye iyamelana nempembelelo.

Imilomo yeSilicon Carbide ayihlali ixesha elide kodwa ikhaphukhaphu kwaye ibangela uxinzelelo oluncinci lwabaqhubi.

Imilomo yeBoron Carbide ayinyangeki kangako kodwa iqine kakhulu kwaye yomelele ukuya kuthi ga kalishumi ubude kuneTungsten Carbide kwaye iphindeke kathathu kuneSilicon Carbide.

Ubungakanani boMlomo wokuqhushumba

Xa uphinda kabini i-diameter ye-orifice, uphinda kabini ubungakanani be-orifice kunye nomthamo womoya kunye ne-abrasive enokuthi idlule kwi-nozzle. Ukuba umlomo wombhobho wesanti mkhulu kakhulu, isantya somoya kunye nomxube obolileyo siphantsi kakhulu kwaye awusebenzi ekuqhunyisweni kwemveliso. Ukuba umlomo wombhobho wesanti umncinci kakhulu, uyacotha ukusebenza kakuhle kokuqhushumba.

Ukufumana umbhobho wakho onemveliso kakhulu, misela ukuba loluphi uxinzelelo lombhobho (PSI) okufuneka uwugcine ukwenzela uqhushumbo oluvelisayo, kwaye ungakanani umthamo womoya isicinezeli sakho esifumanekayo esinokubonelela ngomzuzu (CFM), emva koko ujonge itshathi kwicandelo elilandelayo ukuze ufumane ubungakanani bomlomo wombhobho odibana nezo parameters.

Ubonelelo loMoya

Okokugqibela, ukubonelelwa komoya yeyona nto ibalulekileyo kuqhushumbo. Ukuphakama komthamo womoya oxinzelelweyo, uphezulu uxinzelelo oluveliswa kumlomo. Yandisa isantya samasuntswana abrasive, evumela ukusetyenziswa kwebhobho enkulu kunye nokubonelela ngepateni ye-ankile enzulu Omnye kufuneka akhethe ubungakanani kunye nohlobo lombhobho ngokuxhomekeke kwimveliso yecompressor, iimpawu zomphezulu kunye neenkcukacha zesicelo. Jonga kwitheyibhile engezantsi ukukhetha umlomo ochanekileyo ukugcina uxinzelelo lomoya olufunekayo kumbhobho ngokusekelwe kunikezelo lomoya olukhoyo.

Nangona kunjalo, kubalulekile ukufumana indawo eswiti ilungileyo njengoko ngaphaya komgangatho othile, inqanaba eliphezulu lokurhaxa alinyusi imveliso kwaye umbhobho omkhulu wobungakanani bonyusa inkunkuma.

Iindlela zokonyusa uBomi beNkonzo yeNozzle

1. Kuphephe ukuwisa okanye ukubetha imilomo.

2. Use inqobo yokhetho engentla yokukhetha owona mbhobho wesicelo sakho kunye ne-abrasive.

3. Hlola kwaye ubeke endaweni, njengoko kuyimfuneko, i-gasket, okanye iwasha yombhobho okanye isibambi somlomo ukunceda ukuthintela ukungena komqala wombhobho ukuba uqhunyiswe kude.

4. Hlola kwaye Utshintshe Imilomo. Ingakanani impahla enxitywe kakhulu? Nazi iimvavanyo ezintathu ezilula:

a. Faka i-drill bit yobungakanani obuhambelana nebhore yokuqala yomlomo. Ukuba kukho nayiphi na i-slop, lixesha lokuyibuyisela. Ukunxitywa kweNozzle kuthetha ukulahleka koxinzelelo. Ukulahleka koxinzelelo kuthetha ukulahleka kwemveliso, kukho i-1-1 / 2% yokulahlekelwa kwemveliso kuyo yonke ipowunti yoxinzelelo lomoya elahlekileyo.

b. Bamba umlomo ovulekileyo uye ekukhanyeni kwaye ujonge phantsi. Nayiphi na i-ripple okanye i-orange peel effect ngaphakathi kwe-carbide liner iya kudala i-turbulence yangaphakathi enciphisa i-abrasive velocity. Ukuba ubona nayiphi na into engalinganiyo yokunxiba okanye ukuhla koxinzelelo, lixesha lokubuyisela.

c. Jonga umphandle wombhobho, naye. Izinto ezisetyenziselwa ukwakha imilomo ziqinile, kodwa zinokuba brittle. Imathiriyeli yejacket yeNozzle yenzelwe ukunceda ukukhusela iilitha eziqhawukayo kumonakalo wempembelelo. Ukuba ibhatyi iqhekeziwe okanye ibotshiwe, amathuba okuba i-liner nayo iqhekeziwe. Ukuba i-liner iphukile, nangona i-hairline cracks, i-nozzle kufuneka itshintshwe ngokukhawuleza. Akukhuselekanga ukusebenzisa umlomo oqhekekileyo. Khumbula ukuba yonke imilomo iya kuguga ekugqibeleni. Gcina unikezelo lwemilomo yogcino esandleni ukuze unciphise ixesha lokuphumla.

Ukufumana iinkcukacha ezithe vetshe malunga nemilomo yethu, cofa iwebhusayithi engezantsi, kwaye wamkelekile ukuba uqhagamshelane nathi ngayo nayiphi na imibuzo.
