Inqubo yokusika indiza yamanzi

Ezweni lanamuhla elincintisanayo, zonke izinqubo zokukhiqiza kufanele zihlangabezane nezinjongo ezintathu eziyinhloko, njengokuthi, Ukwenyuka Kokukhiqiza, ukunciphisa ukumosha, Ukuthuthukisa Ikhwalithi kanye nokunciphisa izindleko.Inqubo eyodwa enjalo, ephumelela kakhulu ekwehliseni izindleko futhi ikhiqize amaphrofayili amakhulu ngekhwalithi ephezuluUkusika i-Waterjet.Umshini wokusika i-waterjet ungomunye wemishini ekhiqiza kakhulu enemfucuza encane.Nsuku zonke, abantu babona amandla amanzi.Izigidi zeminyaka, amanzi abelokhu enza izimo ezintsha ngokuguguleka.

Ngalesi simiso, ekusikeni kwe-waterjet, isikhathi simane sincishiswe ngokukhulisa ukucindezela kwamanzi.Ukusika i-waterjet akukhiqizi noma yimaphi amagesi ayingozi noma uketshezi nokushisa phezu kwendawo yokusebenza, kuyinqubo yokusika eguquguqukayo, ephumelelayo futhi ebandayo.I-waterjet isika ngokunemba okukhulu nokuvumelana nezimo, kungakhathaliseki ukuthi hlobo luni lomsebenzi kanye nokwakheka.Ukusika i-waterjet enengcindezi ephezulu futhi kubonakala ngokwemvelo kanye nobungane bomsebenzisi.Unjiniyela wethu unesipiliyoni seminyaka ekusikeni i-waterjet, uma ungathanda ukufunda kabanzi, wamukelekile njaloxhumana nonjiniyela wethungqo

Isebenza kanjani?

Ukusika i-Waterjet kuyindlela yobunjiniyela yokusika izimo ezihlukene noma amajika ezinhlotsheni ezahlukahlukene zezinto ngokusebenzisa amandla asuka kusivinini esikhulu, ukuminyana okuphezulu kanye namanzi anomfutho ophakeme kakhulu.Amanzi acindezelwa aze afike ku-392 MPa (cishe ama-atmospheres angama-4000) futhi akhiqizwa embhobho obhobhozayo omncane (Φ 0.1mm).Iphampu ye-ultrahigh-pressure isetshenziselwa ukucindezela amanzi, lapho isivinini samanzi sifinyelela cishe izikhathi ezintathu zejubane lomsindo, ikhiqiza indiza yamanzi enamandla abhubhisayo.Ingakwazi ukusika noma iyiphi into kunoma yikuphi ukuma noma ijika ngenqubo eyodwa.

Ukushisa okukhiqizwa ngesikhathi sokusika kuzosuswa ngokushesha ukugeleza kwe-jets yamanzi ngesivinini esikhulu futhi akukhiqizi noma yiziphi izinto eziyingozi.Ngeke kube khona umthelela oshisayo ezintweni futhi asikho isidingo sokucutshungulwa kwesibili ngemva kokusika.

Izinhlobo ze-Jet Jet Cutting

Ngokuhambisana nomehluko kumthamo wokusika, ukusika kwejethi yamanzi kuhlukaniswa ngezinhlobo ezimbili, Ukusika kwejethi lamanzi ahlanzekile kanye nokusika i-Abrasive Water jet.

1.  Ukusika ijethi yamanzi ahlanzekile

Ekusikeni kwejethi yamanzi ahlanzekile, amanzi ahlanzekile asetshenziselwa ukusika kuphela ngaphandle kwanoma yiziphi iziqhumane futhi asetshenziselwa ukusika izinto ezithambile ezihlanganisa ukhuni, ipulasitiki, irabha, igwebu, ukuzwa, ukudla namapulasitiki amancane.Umsiki wejethi wamanzi oklanyelwe le njongo kuphela akanalo igumbi lokuxuba noma i-nozzle.Ukuze udale ukusika okunembile ku-workpiece, ipompo yengcindezi ephezulu iphoqa amanzi acindezelayo aphume emgodini.Ayihlaseleki kakhulu uma iqhathaniswa nokusikwa kwejethi yamanzi abrasive.Ayinikezi noma iyiphi ingcindezi eyengeziwe kucezu lokusebenza njengoba ukusakazwa kwejethi nakho kuhle kakhulu.

2.  Ukusika i-waterjet e-abrasive

Ekusikeni kwejethi lamanzi abrasive, izinto ezilimazayo zixubene nejethi yamanzi ukuze kwandiswe amandla okusika.Ngokuxuba nempahla ehuquzelayo, kungenzeka ukusika izinto eziqinile nezilayiniwe ikakhulukazi izinto zobumba, izinsimbi, amatshe namapulasitiki awugqinsi okuhlanganisa i-titanium, insimbi engagqwali ne-aluminium.Umsiki wejethi lamanzi udinga igumbi lokuxuba ukuze lixube ama-abrasives namanzi, elitholakala ekhanda lokusika ngaphambi nje kokuba i-jet e-abrasive ibe khona ohlelweni.Ama-ejenti agunyaziwe wokusika kwejethi yamanzi abrasive igrit emisiwe, i-garnet ne-aluminium oxide.Njengoba ubukhulu bezinto ezibonakalayo noma ubulukhuni bukhula, kufanele kanjalo nobulukhuni bama-abrasives asetshenziswayo.Izinhlobo eziningi zezinto ezibonakalayo zingasikwa ngama-abrasive alungile.Nokho, kukhona okuhlukile okufana nengilazi epholile namadayimane angakwazi ukusikwa ngamanzi abrasive.

Izicelo ze-Water jet cutting

I-Aerospace:Embonini ye-aerospace, zonke izingxenye zidinga ukunemba okuyinkimbinkimbi nokunembile.Iziqondiso ze-aerospace azivumeli noma yiluphi uhlobo lwephutha.Lesi isizathu esiyinhloko sokuthi ukusika kwejethi yamanzi kuyingxenye ebalulekile yokwenziwa kwezingxenye ze-aerospace yezinjini zejethi kumaphaneli okulawula aklanywe ngokwezifiso.Ukusika ijethi yamanzi abrasive kusetshenziswa embonini ye-aerospace ukusika insimbi, ithusi, i-Inconel ne-aluminium.

Imboni yezimoto:Kokubili ukusika kwejethi yamanzi ahlanzekile futhi abrasive kuyisixazululo esiphelele semboni yezimoto ngenxa yokuguquguquka kwayo okunamandla nokuguquguquka okuphezulu.Ingakwazi ukusika izinto ezifana ne-aluminium, insimbi nama-composites kanjalo nezicabha noma okhaphethi bengaphakathi lemoto.Ayikhiqizi noma yimaphi ama-burs, imiphetho emangelengele kanye nezingcindezi zemishini ebusweni bokusikeka.

Imboni yezokwelapha:Ukuze wenze izimila zezokwelapha ezisindisa ukuphila namathuluzi okuhlinza, akukho okubaluleke ukwedlula ukunemba kanye namazinga aphezulu ekhwalithi.Ukusika i-abrasive jet kungakuqinisekisa kokubili njengoba kusikeka ngokunemba okuphezulu kanye nokuma okunembile noma amajika ngaphandle kwemiphumela emibi engathandeki.

Imboni Yokudla:Ukusika izinhlobonhlobo zokudla, ukusika ijethi yamanzi ahlanzekile kuyinqubo yokukhiqiza yesimanje.Inyama, izinhlanzi, izinkukhu, ukudla okuqandisiwe, amakhekhe ngisho namaswidi anqunywa ngamandla amanzi ahlanzekile.

I-Architecture:Ngokusika i-jet abrasive, umuntu angakwazi ukusika zonke izinhlobo zamatshe namathayili njenge-granite, i-limestone, i-slate ne-marble phakathi kwezinye izinto zokwakha phansi kanye namathayili e-ceramic noma ama-sinkholes amakhishi noma izindlu zangasese.

I-PRO kanye ne-CONs ye-Water jet cutting

I-PROS:

Ukunemba Okudlulele:Inokunemba phakathi kweyintshi engu-±0.003 ukuya ku-±0.005 iyintshi.Njengoba ijubane lokusika lingashintshwa, ukusika okuphakathi kanye nezingxenye ezinemiphetho eminingi zingakhiqizwa.

Isiphetho sesibili:Ayidali noma yiziphi izindawo ezimaholoholo, ama-burrs noma ukungapheleli okususa isidingo sokuqeda okwesibili.Ikhiqiza ama-kerfs amancane kanye nokuqedwa okubushelelezi.

Ayikho Indawo Ethintekile Ukushisa (HAZ):Njengoba kuyinqubo yokusika abandayo, ayidingi ukudala noma iyiphi i-HAZ.Izonikeza izingxenye zokugcina ezinekhwalithi ephezulu yonqenqema kanye nezakhiwo ezinokwethenjelwa ngaphandle kokunikeza noma yikuphi ukucindezeleka ezingxenyeni.

Isimeme Kakhulu:Izingxenye eziqediwe nazo azidingi noma yimiphi imisebenzi ngemva kokucubungula njengokwelashwa kokushisa.Ngaphezu kwalokho, ayidingi amafutha okupholisa noma izinto zokugcoba njengoba indiza yamanzi ngokwayo isebenza njengesibambisi.

Ukusebenza Okuphezulu:Kuyindlela ephumelela kakhulu yokusika ngenxa yamandla ayo nokuphatha izinto.Okuningi kokusebenza kahle kwawo kungabonakala ekugayweni kabusha kwamanzi ewasebenzisayo kanye nokususwa kwesidingo sokucutshungulwa kwesibili.

I-CONS:

Izindleko zokuqala:Ukucwaninga nokwengeza izinto ezi-abrasive kubalulekile ukuze usike kahle.

Ukuhluleka kwe-Orifice:Lokhu kuvame ukwenzeka emishinini yokusika ijethi yamanzi esezingeni eliphansi futhi ngokuvamile kuzophazamisa ukukhiqiza futhi kwenyuse izindleko zokukhiqiza.

Isikhathi sokusika:Isikhathi sokusika siphakeme kunamathuluzi okusika endabuko aphumela ekukhiqizweni okuncane.

Imibuzo Evame Ukubuzwa mayelana nokusikwa kwejethi yamanzi

1.  Ngingakwazi ukusika izinto eziwugqinsi ngokusika ijethi yamanzi?

Yebo, izinto eziwugqinsi zingasikwa ngomshini wokusika amanzi wejethi.Amajethi amanzi ashubile awasebenzi kahle ezintweni eziwugqinsi futhi ukunemba kunciphisa izinto eziwugqinsi.

2.  Yikuphi okungcono?Ukusika i-Waterjet,ukusika i-plasma or ukusika laser?

Izinto ezintathu ezibaluleke kakhulu zokuthola ukuthi iyiphi engcono Izindleko, Isivinini Sokusebenza kanye nekhwalithi Yokusika.Ukusika kwe-Waterjet kunekhwalithi ephezulu yokusika, inqubo yokusika ehamba kancane kanye nezindleko eziphakathi uma kuqhathaniswa ne-plasma ne-laser.

3.  Uyini umehluko phakathi kwamajethi wamanzi ahlanzekile nangama-abrasive?

Amajethi wamanzi ahlanzekile asebenzisa amanzi ahlanzekile esikhundleni sama-abrasives futhi amanzi asetshenziswe kule nqubo angasetshenziswa kabusha.Isetshenziselwa ukusika izinto eziqinile ezithambile nezimaphakathi.Amajethi amanzi abrasive asebenzisa izinto eziqhumayo futhi asetshenziselwa ukusika izinto eziqinile.I-Garnet iyinto esetshenziswa kakhulu e-abrasive ngenxa yokuqina kwayo okuphezulu nokutholakala kwayo.
