Ngaba awuyazi indlela yokukhetha umbhobho wokuqhushumba? Ukulandela amanyathelo amane, kulula!
Ngaba awuyazi indlela yokukhetha umbhobho wokuqhushumba? Ukulandela amanyathelo amane, kulula!
--Amanyathelo amane akuxelela indlela yokukhetha imilomo efanelekileyo yokuqhushumba
Imilomo yokuqhunyiswa kwesanti iyilwe kwiintlobo ezahlukeneyo ezinobukhulu obahlukeneyo kunye neemilo ezivela kwizinto ezahlukeneyo. Ukukhetha i-sandblast nozzle efanelekileyo kwisicelo ngasinye yinto nje yokuqonda izinto eziguquguqukayo ezichaphazela ukucoca ukusebenza kunye neendleko zomsebenzi. Ukuba awuyazi ukuba ungazikhethela njani umlomo womlomo ofanelekileyo, landela la manyathelo ama-4 angezantsi.
1. Khetha ubungakanani boMbhobho weBore
Xa ukhetha umbhobho, iqala ngeyakhoumoya compressor. Nje ukuba uqonde ukuba ubungakanani becompressor yakho buchaphazela amandla emveliso, uya kufuna ukujongaubungakanani bomlomo. Khetha umlomo onombhobho omncinci kakhulu kwaye uya kushiya umthamo wokuqhushumba etafileni. Mkhulu kakhulu kwaye uya kuswela uxinzelelo lokuqhushumba ngendlela enemveliso.
Itheyibhile engezantsi ibonisa ulungelelwaniso phakathi komthamo womoya, ubungakanani bomlomo, kunye noxinzelelo lombhobho kwaye ihlala isetyenziswa kushishino ukukhetha ubungakanani bomlomo. Olona ncedo lwayo kukukhetha obona bungakanani bomlomo womlomo ofanelekileyo woxinzelelo lomlomo olufunekayo ukwenza umsebenzi.
2. Khetha iMilo yoMlomo
Okulandelayo yiukumila komlomo. Imilomo iza kwiimilo ezimbini ezisisiseko:SibelekilekwayeVenturi, ngeendidi ezininzi zemilomo yeVenturi.
Imilomo yeBore eNgqo(Inombolo 1) yenza ipateni eqinileyo yokuqhushumba kwendawo okanye umsebenzi wekhabhathi yokuqhushumba. Ezi zilungele imisebenzi emincinci efana nokucoca, ukubunjwa kwe-weld seam, ukucoca i-handrails, amanyathelo, i-grillwork, okanye ilitye lokukrola kunye nezinye izinto.
IVenturi yazala imilomo(Amanani 2 kunye ne-3) yenza ipateni yokuqhuma okubanzi kunye nokwandisa isantya sokukrazula ukuya kuthi ga kwi-100% kuxinzelelo olunikiweyo.
Imilomo yeVenturi lolona khetho lubalaseleyo lwemveliso enkulu xa kuqhunyiswa imiphezulu emikhulu. Imilomo ye-venturi ephindwe kabini kunye nomqala obanzi ziinguqulelo eziphuculweyo zombhobho omde wesimbo se-venturi.
Ii-venturi kabiniisimbo (iNombolo yesi-4) inokucingelwa njengemilomo emibini elandelelanayo enesithuba kunye nemingxuma phakathi ukuvumela ukufakwa komoya kwindawo esezantsi yomlambo. Isiphelo sokuphuma sikwabanzi kunombhobho wesiqhelo. Zombini izilungiso zenziwa ukwandisa ubungakanani bepateni yokuqhuma kunye nokunciphisa ilahleko yesantya se-abrasive.
Imilomo ebanzi yomqala(Inombolo yesi-5) ibonisa umqala omkhulu wokungena kunye nombhobho omkhulu wokuphuma. Xa zidibene nombhobho wobungakanani obufanayo zinokubonelela ngokunyuka kwe-15% kwimveliso phezu kwemibhobho yomqala omncinci. Ikwangumbono olungileyo ukuba nemilomo ye-engile ifumaneke kwiindawo eziqinileyo njengeletisi yomtshakazi, ngasemva kweeflange, okanye imibhobho engaphakathi. Abaqhubi abaninzi bachitha i-abrasives kunye nexesha lokulinda i-ricochet ukuba yenze umsebenzi. Ixesha elincinci elithathayo ukutshintshela kwi-umbhobho we-engileusoloko uchacha ngokukhawuleza, kwaye ixesha lilonke emsebenzini liyancitshiswa.
3. Khetha Isixhobo soMlomo
Nje ukuba ugqibe ubungakanani bombhobho kunye nokumila, uya kufuna ukuqwalaselaimpahlai-nozzle liner yenziwe ngayo. Imiba emithathu ephambili ekukhetheni imathiriyeli efanelekileyo yomlomo womlomo kukuhlala ixesha elide, ukuxhathisa impembelelo, kunye nexabiso.
Ukukhethwa kwemathiriyeli yombhobho kuxhomekeke kwi-abrasive oyikhethayo, ukuba uqhushumba kangaphi, ubungakanani bomsebenzi, kunye nobunzima bendawo yomsebenzi. Nazi izikhokelo zesicelo ngokubanzi kwizinto ezahlukeneyo.
Imilomo ye-tungsten carbide:Ngaba zinika ubomi obude kunye noqoqosho xa ukuphathwa rough ayinakuphetshwa. Ilungele ukuqhushumba kwe-slag, iglasi, kunye ne-mineral abrasives.
I-silicon carbideimilomo:Impembelelo exhathisayo kwaye yomelele njenge-tungsten carbide, kodwa malunga nesinye kwisithathu kuphela sobunzima bemilomo ye-tungsten carbide. Olona khetho lubalaseleyo xa abaqhubi besemsebenzini ixesha elide kwaye bakhetha umlomo okhanyayo.
Imilomo yeBoron carbide:Inzima kakhulu kwaye yomelele, kodwa i-brittle. I-Boron carbide ifanelekile kwii-abrasives ezinobundlobongela ezifana ne-aluminium oxide kunye ne-aggregates yeeminerali ezikhethiweyo xa ukuphatha kakubi kunokuphetshwa. IBoron carbide iqhele ukunxiba itungsten carbide izihlandlo ezihlanu ukuya kwezilishumi kunye nesilicon carbide kabini ukuya kathathu xa kusetyenziswa iziqhushumbisi ezinobundlobongela. Ixabiso nalo liphezulu phakathi kwabo.
4. Khetha umsonto kunye nebhatyi
Ekugqibeleni, kufuneka ukhethe izinto eziphathekayo zejacket ezikhusela ibhore. Kufuneka kwakhona ucinge ukuba loluphi uhlobo lwentambo olulungela iimfuno zakho zesanti: intambo ecolekileyo okanye erhabaxa (ikhontrakta).
1) Ibhatyi yeNozzle
Ibhatyi yeAluminiyam:Iibhatyi ze-Aluminiyam zinika umgangatho ophezulu kakhulu wokukhusela kumonakalo wempembelelo kwi-lightweight.
Ibhatyi yentsimbi:Iibhatyi zensimbi zinika umgangatho ophezulu kakhulu wokukhusela kumonakalo wempembelelo kwi-heavyweight.
Ibhatyi yerabha:Ibhatyi yerabha iKhaphukhaphu ngelixa isabonelela ngokhuseleko lwefuthe.
2) Uhlobo lwentambo
Umsonto orhabaxa (uKontraka).
Umsonto-umgangatho weshishini kwi-4½ imisonto nge-intshi nganye (TPI) (114mm), esi simbo sinciphisa kakhulu ithuba lokuwela umsonto kwaye kulula kakhulu ukuyifaka.
Umsonto Omhle(NPSM Umsonto)
UmGangatho weSizwe oHlangeneyo oLungileyo oLungileyo woMbhobho weMechanical (NPSM) ngumgangatho weShishini othe ngqo osetyenziswa ngokubanzi kuMntla Melika.
IINGCINGA ZOKUGQIBELA
Umoya omkhulu kunye nemilomo emikhulu ikhokelela kumazinga emveliso amakhulu, kodwa kukumila komlomo wombhobho omisela ukukhawuleziswa kwamasuntswana kunye nobungakanani bepateni yokuqhushumba.
Kuzo zonke, akukho nozzle ilungileyo, inqaku eliphambili kukufumana imilomo efanelekileyo kakhulu yokusetyenziswa kwakho.
