Imibhobho yokuqhunyiswa kabini kweVenturi 

Imilomo eqhumayo idla ngokuza kwiimilo ezimbini ezisisiseko: i-straight bore kunye ne-venturi, enezinto ezininzi ezahlukeneyo zemilomo ye-venturi.

Imilomo yeVenturi ikholisa ukwahlulwa ibe yi-single-inlet venturi kunye ne-double-inlet venturi nozzle.

Umbhobho we-venturi omnye ngumlomo wesiqhelo we-venturi. Iyilwe kwindawo eguquguqukayo ende ene tapered, enecandelo elifutshane elithe tyaba elithe tye, lilandelwa sisiphelo esiphambukayo eside esiba banzi njengoko ufikelela kwisiphelo sokuphuma somlomo. Le milo iyilelwe ukuvelisa isiphumo esikhawulezisa kakhulu ukuhamba komoya kunye namasuntswana kwaye ngokulinganayo isasaze i-abrasive phezu kwayo yonke ipateni yokuqhushumba, inika malunga ne-40% yezinga lemveliso enkulu kunombhobho othe ngqo.

Umbhobho we-venturi double unokucingelwa njengemilomo emibini elandelelanayo enesithuba kunye nemingxuma phakathi ukuvumela ukufakwa komoya we-atmospheri kwindawo esezantsi yomlambo. Isiphelo sokuphuma sikwabanzi kunombhobho oqhelekileyo wokuqhushumba. Imilomo ye-venturi ephindwe kabini ibonelela malunga ne-35% yepateni yokuqhushumba enkulu kunesiqhelo soqhushumbo lwe-venturi enelahleko nje encinci kwisantya esirhabaxa. Ngokubonelela ngepateni enkulu yokuqhushumba, umbhobho oqhumayo wenza ukuba ukuqhuma kwe-abrasive kuphumelele. Ifanelekile kwimisebenzi apho ipateni ebanzi yokuqhushumba ifuneka.

Kwi-BSTEC, ungafumana iintlobo ezininzi zemilomo ye-venturi ephindwe kabini.

1.     Ihlelwa ngokweNozzle Liner Material

• INozzle yeSilicon Carbide kabini yeVenturi:ubomi benkonzo kunye nokuqina kufana ne-tungsten carbide, kodwa kuphela malunga nesinye kwisithathu sobunzima bemibhobho ye-tungsten carbide. Imilomo ye-silicon ye-carbide lukhetho oluhle kakhulu xa abaqhubi besemsebenzini ixesha elide kwaye bekhetha imilomo ekhaphukhaphu.

• I-Boron Carbide i-Double Venturi Nozzle:eyona nto ihlala ixesha elide isetyenziselwa imilomo yokuqhushumba. Iyodlula itungsten carbide ngamaxesha amahlanu ukuya kwalishumi kunye nesilicon carbide kabini ukuya kathathu xa kusetyenziswa abrasives andlongondlongo. Umbhobho we-Boron carbide ulungele iziqhushumbisi ezinobundlobongela ezifana ne-aluminium oxide kunye ne-aggregates yeeminerali ezikhethiweyo xa ukuphathwa rhabaxa kunokuphetshwa.

2.    Ihlelwa ngokohlobo lwemisonto

• Umsonto orhabaxa (weKontraki):Umsonto womgangatho weshishini kwi-4½ imisonto nge-intshi nganye (TPI) (114mm), esi simbo sinciphisa kakhulu ithuba lokuwela umsonto kwaye kulula kakhulu ukuyifaka.

• Fine Thread(NPSM Umsonto): UmGangatho weSizwe oHlangeneyo oLungileyo oLungileyo weMibhobho yeMechanical (NPSM) ngumgangatho we-Industry standard thread straight esetyenziswa ngokubanzi eMntla Melika.

3.    Ihlelwa yiNozzle Jacket

• Ibhatyi yeAluminiyam:nikezela ngenqanaba eliphezulu kakhulu lokhuseleko ngokuchasene nomonakalo wempembelelo kwi-lightweight.

• Ibhatyi yentsimbi:nikela umgangatho ophezulu kakhulu wokukhusela kumonakalo wempembelelo kwi-heavyweight.
