Ukusika i-Waterjet kungase kube indlela elula yokucubungula, kodwa ifakwe i-punch enamandla futhi idinga opharetha ukuthi aqaphele ukuguga nokunemba kwezingxenye eziningi.
Indlela elula yokusika ijethi yamanzi iyinqubo yokusika amajethi amanzi anomfutho ophezulu abe yizinto zokwakha. Lobu buchwepheshe buvame ukuhambisana nobunye ubuchwepheshe bokucubungula, njengokugaya, i-laser, i-EDM, ne-plasma. Enqubweni yejethi yamanzi, azikho izinto eziyingozi noma umusi owenziwe, futhi akukho ndawo ethintekile ukushisa noma ukucindezeleka kwemishini okwakhiwa. Amajethi amanzi angasika imininingwane emincane kakhulu etsheni, engilazini nasensimbi; ngokushesha ukumba izimbobo titanium; ukusika ukudla; futhi abulale ngisho namagciwane eziphuzweni namadiphu.
Yonke imishini ye-waterjet inepompo engacindezela amanzi ukuze ahanjiswe ekhanda lokusika, lapho liguqulwa khona libe ukugeleza kwe-supersonic. Kunezinhlobo ezimbili eziyinhloko zamaphampu: amaphampu asekelwe kudrayivu eqondile namaphampu asekelwe ku-booster.
Indima yephampu yedrayivu eqondile ifana neyomshini wokuhlanza umfutho ophezulu, futhi iphampu enamasilinda amathathu ishayela ama-plunger amathathu ngqo enjini kagesi. Ingcindezi ephezulu yokusebenza eqhubekayo ingu-10% kuya ku-25% ephansi kunamaphampu e-booster afanayo, kodwa lokhu kusawagcina ephakathi kuka-20,000 no-50,000 psi.
Amaphampu asuselwa ku-intensifier akha iningi lamaphampu omfutho ophakeme kakhulu (okungukuthi, amaphampu angaphezu kuka-30,000 psi). Lawa maphampu aqukethe amasekhethi amabili oketshezi, eyodwa eyamanzi kanti enye ingeyamanzi. Isihlungi se-inlet samanzi siqala sidlule kusihlungi se-cartridge encane esingu-1 bese kuba isihlungi esingu-0.45 micron ukuze simunce emanzini avamile kampompi. Lawa manzi angena empompini ye-booster. Ngaphambi kokuthi ingene empompini ye-booster, ingcindezi yepompo ye-booster igcinwa cishe ku-90 psi. Lapha, ingcindezi ikhuphuke ibe ngu-60,000 psi. Ngaphambi kokuba amanzi agcine eshiya isethi yephampu futhi afinyelele ekhanda lokusika ngepayipi, amanzi adlula kumshini wokuthuthumela. Idivayisi ingacindezela ukushintshashintsha kwengcindezi ukuze ithuthukise ukungaguquguquki futhi isuse ama-pulses ashiya amamaki kucezu lokusebenza.
Kumjikelezo we-hydraulic, injini kagesi phakathi kwamamotho kagesi idonsa uwoyela ethangini likawoyela futhi iyicindezele. Uwoyela ocindezelwe ugeleza uye endaweni eningi, futhi i-valve ye-manifold ifaka ngokushintshana uwoyela we-hydraulic nhlangothi zombili ze-biscuit ne-plunger assembly ukuze ikhiqize isenzo sokushaywa kwe-booster. Njengoba ingaphezulu le-plunger lincane kunelebhisikidi, ukucindezela kwamafutha "kukhulisa" ukucindezela kwamanzi.
I-booster iyipompo ephindaphindayo, okusho ukuthi umhlangano wamabhisikidi ne-plunger uletha amanzi anomfutho ophezulu ukusuka ohlangothini olulodwa lwe-booster, kuyilapho amanzi anengcindezi ephansi egcwalisa olunye uhlangothi. I-recirculation iphinde ivumele uwoyela we-hydraulic ukuthi uphole uma ubuyela ethangini. I-valve yokuhlola iqinisekisa ukuthi amanzi anomfutho ophansi kanye nomfutho ophezulu angageleza ngendlela eyodwa kuphela. Amasilinda anengcindezi ephezulu namakepisi okugcina ahlanganisa izingxenye ze-plunger namabhisikidi kumele ahlangabezane nezidingo ezikhethekile ukuze amelane namandla enqubo kanye nemijikelezo yokucindezela engapheli. Lonke uhlelo luklanyelwe ukuhluleka kancane kancane, futhi ukuvuza kuzogeleza "emigodini yokudonsa" ekhethekile, engaqashwa opharetha ukuze kuhlelwe kangcono ukugcinwa okuvamile.
Ipayipi elikhethekile lokucindezela okuphezulu lihambisa amanzi ekhanda lokusika. Ipayipi ingaphinde inikeze inkululeko yokunyakaza kwekhanda lokusika, kuye ngokuthi ubukhulu bepayipi. Insimbi engagqwali iyinto ekhethwayo kula mapayipi, futhi kukhona osayizi abathathu abajwayelekile. Amapayipi ensimbi anobubanzi be-intshi engu-1/4 aguquguqukayo ngokwanele ukuze axhumeke kumishini yezemidlalo, kodwa awanconywa ukuthutha okude kwamanzi anomfutho ophezulu. Njengoba leli shubhu kulula ukugoba, ngisho nakumqulu, ubude obuyizinyawo eziyi-10 kuye kwezingu-20 bungafinyelela ukunyakaza kuka-X, Y, no-Z. Amapayipi amakhulu angu-3/8-intshi angu-3/8-intshi ngokuvamile athwala amanzi ukusuka empompini ukuya phansi kwezinto ezihambayo. Nakuba ingagotshwa, ngokuvamile ayifaneleki imishini yokunyakaza yamapayipi. Ipayipi elikhulu kunawo wonke, elilinganisa ama-intshi angu-9/16, lingcono kakhulu ukuthutha amanzi anomfutho ophezulu ngokuhamba amabanga amade. I-diameter enkulu isiza ukunciphisa ukulahlekelwa kwengcindezi. Amapayipi alo sayizi ahambisana kakhulu namaphampu amakhulu, ngoba inani elikhulu lamanzi okucindezela okukhulu libuye libe nengozi enkulu yokulahlekelwa kwengcindezi okungenzeka. Kodwa-ke, amapayipi alo sayizi awakwazi ukugoba, futhi ukufakwa kudinga ukufakwa emakhoneni.
Umshini wokusika ijethi yamanzi ahlanzekile uwumshini wokuqala wokusika ijethi yamanzi, futhi umlando wawo ungalandelelwa emuva ekuqaleni kwawo-1970. Uma kuqhathaniswa nokuthintana noma ukuphefumula kwezinto, zikhiqiza amanzi amancane ezintweni, ngakho-ke zilungele ukukhiqizwa kwemikhiqizo efana nezimoto zangaphakathi kanye namanabukeni alahlwayo. Uketshezi luzacile kakhulu-amayintshi angu-0.004 ukuya kumayintshi angu-0.010 ububanzi-futhi lunikeza amajiyometri anemininingwane eminingi ngokulahleka kwempahla okuncane kakhulu. Amandla okusika aphansi kakhulu, futhi ukulungisa ngokuvamile kulula. Le mishini ifaneleka kakhulu ukusebenza amahora angama-24.
Uma ucabangela ikhanda lokusika lomshini we-waterjet ohlanzekile, kubalulekile ukukhumbula ukuthi isivinini sokugeleza yizicucu ezincane noma izinhlayiya zezinto ezidabulayo, hhayi ukucindezela. Ukuze kuzuzwe lesi sivinini esikhulu, amanzi acindezelwe ageleza embotsheni encane eyigugu (imvamisa isafire, irubi noma idayimane) egxilwe ekugcineni komlomo. Ukusika okuvamile kusebenzisa i-orifice diameter engu-0.004 amayintshi ukuya ku-0.010 amayintshi, kuyilapho izinhlelo ezikhethekile (ezifana nokhonkolo ofuthwe) zingasebenzisa osayizi abangafika kumayintshi angu-0.10. Ku-40,000 psi, ukugeleza okuvela ku-orifice kuhamba ngesivinini esicishe sibe ngu-Mach 2, futhi ku-60,000 psi, ukugeleza kudlula i-Mach 3.
Ubucwebe obuhlukene bunobuchwepheshe obuhlukile ekusikeni kwe-waterjet. I-Sapphire iyinto evamile yenhloso evamile. Zihlala cishe amahora angama-50 kuye kwayi-100 wesikhathi sokusika, nakuba isicelo se-waterjet esibi sinciphisa lezi zikhathi. Amarubi awafanelekile ukusika i-waterjet ehlanzekile, kodwa ukugeleza kwamanzi akukhiqizayo kulungele kakhulu ukusika i-abrasive. Enqubweni yokusika i-abrasive, isikhathi sokusika amarubi cishe amahora angama-50 kuya kwangu-100. Amadayimane abiza kakhulu kunamasafire namarubi, kodwa isikhathi sokusika siphakathi kwamahora angu-800 nezi-2,000. Lokhu kwenza idayimane lifaneleke ikakhulukazi ukusebenza amahora angama-24. Kwezinye izimo, i-diamond orifice ingabuye ihlanzwe nge-ultrasonically futhi isetshenziswe kabusha.
Emshinini we-waterjet abrasive, indlela yokukhishwa kwezinto akuyona ukugeleza kwamanzi ngokwawo. Ngokuphambene, ukugeleza kusheshisa izinhlayiya ezilimazayo ukugqwala okubalulekile. Le mishini inamandla aphindwe izikhathi eziyizinkulungwane kunemishini yokusika ijethi yamanzi ahlanzekile, futhi ingasika izinto eziqinile njengensimbi, itshe, izinto eziyinhlanganisela, nezitsha zobumba.
I-abrasive stream inkulu kunomfula ohlanzekile wejethi yamanzi, enobubanzi obuphakathi kuka-0.020 amayintshi no-0.050 amayintshi. Bangakwazi ukusika izitaki nezinto zokwakha kuze kufike kumayintshi angu-10 ugqinsi ngaphandle kokudala izindawo ezithinteke ukushisa noma ukucindezeleka komshini. Nakuba amandla abo enyukile, amandla okusika omfudlana abrasive asengaphansi kwephawundi elilodwa. Cishe yonke imisebenzi yejethi elimazayo isebenzisa idivayisi yejethi, futhi ingashintsha kalula isuke ekusetshenzisweni kwekhanda elilodwa iye ekusetshenzisweni kwamakhanda amaningi, ngisho nejethi lamanzi abrasive lingaguqulwa libe ijethi lamanzi elihlanzekile.
I-abrasive iqinile, ikhethwe ngokukhethekile futhi inosayizi wesihlabathi-imvamisa i-garnet. Osayizi begridi abahlukene bafanele imisebenzi eyahlukene. Indawo ebushelelezi ingatholwa ngama-abrasives anezikhala angu-120, kuyilapho ama-abrasives anezikhala angama-80 afakazele ukuthi afaneleka kakhulu ekusetshenzisweni kwenjongo evamile. Isivinini sokusika esingu-50 se-abrasive siyashesha, kodwa ingaphezulu liqinile kancane.
Nakuba amajethi amanzi kulula ukusebenza kuneminye imishini eminingi, ithubhu yokuxuba idinga ukunakwa komsebenzisi. Amandla okusheshisa aleli shubhu afana nombhobho wesibhamu, osayizi abahlukene nempilo yokushintsha ehlukile. Ishubhu yokuxuba ehlala isikhathi eside iwukuqamba okusha ekusikeni ijethi yamanzi abrasive, kodwa ishubhu lisentekenteke kakhulu-uma ikhanda elisikayo lihlangana ne-fixture, into esindayo, noma into ehlosiwe, ishubhu ingase ibhuleki. Amapayipi alimele awakwazi ukulungiswa, ngakho ukugcina izindleko ziphansi kudinga ukuncishiswa ukushintshwa. Imishini yesimanje ivamise ukuba nomsebenzi wokubona ukushayisana okuzenzakalelayo ukuvimbela ukushayisana neshubhu yokuxuba.
Ibanga lokuhlukanisa phakathi kweshubhu yokuxuba nento eqondiwe ngokuvamile ingamayintshi angu-0.010 ukuya ku-0.200 amayintshi, kodwa opharetha kufanele akhumbule ukuthi ukuhlukana okukhulu kuno-0.080 amayintshi kuzobangela isithwathwa phezulu konqenqema olusikiwe lwengxenye. Ukusika ngaphansi kwamanzi kanye nezinye izindlela kunganciphisa noma kuqede lesi sithwathwa.
Ekuqaleni, ithubhu yokuxuba yenziwe nge-tungsten carbide futhi yayinempilo yesevisi yamahora amane kuya kwayisithupha okusika. Amapayipi ahlanganisiwe wanamuhla angabizi kakhulu angafinyelela impilo yokusika amahora angama-35 kuya kwangama-60 futhi anconyelwe ukusika noma ukuqeqesha ama-opharetha amasha. Ishubhu le-carbide elihlanganisiwe lenza impilo yalo yesevisi ibe ngamahora okusika angama-80 kuye kwangama-90. Ishubhu ye-carbide ehlanganisiwe yekhwalithi ephezulu inokuphila kokusika okungamahora ayi-100 kuya kwayi-150, ifaneleka ukunemba nomsebenzi wansuku zonke, futhi ikhombisa ukugqokwa kwe-concentric okubikezelwa kakhulu.
Ngaphezu kokuhlinzeka ngokunyakaza, amathuluzi omshini we-waterjet kumele futhi afake indlela yokuvikela isiqeshana somsebenzi kanye nohlelo lokuqoqa nokuqoqa amanzi kanye nemfucumfucu emisebenzini yomshini.
Imishini emile kanye ne-one-dimensional yimishini yamanzi elula kakhulu. Amajethi wamanzi amile avame ukusetshenziswa endaweni yendiza ukunquma izinto eziyinhlanganisela. Umsebenzisi uphakela impahla emfudlaneni njengesaha, kuyilapho umbambeli eqoqa umfudlana nemfucumfucu. Amajethi amaningi amile angamanzi ahlanzekile, kodwa hhayi wonke. Umshini wokusika uhlukile komshini omile, lapho imikhiqizo efana nephepha idliswa ngomshini, futhi indiza yamanzi isika umkhiqizo ube ububanzi obuthile. Umshini wokunqamula umshini ohamba eduze kwe-eksisi. Bavame ukusebenza ngemishini yokusika ukuze benze amaphethini afana negridi emikhiqizweni efana nemishini yokuthengisa efana nama-brownies. Umshini wokusika usika umkhiqizo ube ububanzi obuthile, kuyilapho umshini wokusika unqamula umkhiqizo ophakelwa ngaphansi kwawo.
Ama-opharetha akufanele asebenzise mathupha lolu hlobo lwejethi yamanzi abrasive. Kunzima ukuhambisa into esikiwe ngesivinini esiqondile futhi esingaguquki, futhi kuyingozi kakhulu. Abakhiqizi abaningi ngeke baze bacaphune imishini yalezi zilungiselelo.
Ithebula le-XY, elibizwa nangokuthi umshini wokusika i-flatbed, liwumshini wokusika we-waterjet onezinhlangothi ezimbili ezivame kakhulu. Amajethi amanzi ahlanzekile asika ama-gaskets, amapulasitiki, irabha, negwebu, kuyilapho amamodeli abrasive esika izinsimbi, izinhlanganisela, ingilazi, itshe, nezitsha zobumba. Ibhentshi lokusebenzela lingaba lincane njengezinyawo ezi-2 × 4 noma libe likhulu njengo-30 × 100 izinyawo. Ngokuvamile, ukulawulwa kwala mathuluzi omshini kuphathwa yi-CNC noma i-PC. Ama-Servo motors, ngokuvamile anempendulo evaliwe, aqinisekisa ubuqotho besikhundla nesivinini. Iyunithi eyisisekelo ihlanganisa imihlahlandlela eqondile, izindlu ezithwele nezikulufu zamabhola, kuyilapho iyunithi yebhuloho ihlanganisa lobu buchwepheshe, futhi ithangi lokuqoqa lihlanganisa ukusekela okubalulekile.
Amabhentshi okusebenzela e-XY ngokuvamile afika ngezitayela ezimbili: ibhentshi lokusebenzela le-gantry elimaphakathi nesitimela lihlanganisa ama-base guide rails kanye nebhuloho, kuyilapho ibhentshi le-cantilever lisebenzisa isisekelo nebhuloho eliqinile. Zombili izinhlobo zemishini zihlanganisa uhlobo oluthile lokulungiswa kokuphakama kwekhanda. Lokhu kulungiswa kwe-Z-axis kungathatha uhlobo lwe-crank manual, isikulufu sikagesi, noma isikulufu se-servo esihleleleka ngokugcwele.
I-sump ku-workbench ye-XY ngokuvamile ithangi lamanzi eligcwele amanzi, elifakwe ama-grille noma ama-slats ukusekela ucezu lokusebenza. Inqubo yokusika idla lezi zisekelo kancane kancane. Isicupho singahlanzwa ngokuzenzakalelayo, imfucuza igcinwe esitsheni, noma ingaba ngesandla, futhi opharetha uhlale efosholo ikani.
Njengoba ingxenye yezinto ezicishe zingabi bikho indawo eyisicaba iyanda, amakhono e-axis emihlanu (noma ngaphezulu) abalulekile ekusikeni kwejethi yamanzi yesimanje. Ngenhlanhla, i-lightweight cutter head kanye namandla aphansi okubuyisela emuva phakathi nenqubo yokusika inikeza onjiniyela bokuklama inkululeko leyo umshini wokulayisha umthwalo omkhulu ongenayo. Ukusika i-waterjet ye-five-axis ekuqaleni kwakusebenzisa isistimu yesifanekiso, kodwa abasebenzisi ngokushesha baphendukela kuma-axis amahlanu ahlelekayo ukuze basuse izindleko zesifanekiso.
Kodwa-ke, noma kunesoftware ezinikele, ukusika kwe-3D kuyinkimbinkimbi kunokusika kwe-2D. Ingxenye yomsila oyinhlanganisela ye-Boeing 777 iyisibonelo esidlulele. Okokuqala, u-opharetha ulayisha uhlelo futhi ahlele abasebenzi be-"pogostick" abaguquguqukayo. I-crane engaphezulu ithutha izinto zezingxenye, futhi ibha yasentwasahlobo ikhishwe ekuphakameni okufanele futhi izingxenye zilungisiwe. I-eksisi ye-Z ekhethekile engasikiwe isebenzisa i-probe yokuxhumana ukuze imise ngokunembile ingxenye emkhathini, kanye namaphoyinti esampula ukuze kutholwe ukuphakama kwengxenye efanele kanye nesiqondiso. Ngemva kwalokho, uhlelo luqondiswa kabusha endaweni yangempela yengxenye; i-probe ihoxisa ukuze ivule indawo ye-axis ye-Z yekhanda elisika; uhlelo lugijima ukuze lulawule zonke izimbazo ezinhlanu ukugcina inhloko yokusika ibheke phezulu ukuze isikwe, futhi isebenze njengoba kudingekile Ukuhamba ngesivinini esinembile.
Ama-abrasives ayadingeka ukuze usike izinto eziyinhlanganisela noma iyiphi insimbi enkulu kuno-0.05 amayintshi, okusho ukuthi i-ejector idinga ukuvinjelwa ekusikeni ibha yasentwasahlobo kanye nombhede wamathuluzi ngemva kokusika. Ukuthwebula amaphuzu akhethekile kuyindlela engcono kakhulu yokufeza ukusika i-waterjet yama-axis amahlanu. Ukuhlola kubonise ukuthi lobu buchwepheshe bungamisa indiza yejethi enamandla angu-50 ngaphansi kwama-intshi angu-6. Uhlaka olumise okwe-C luxhuma isibambi esihlakaleni se-axis engu-Z ukuze sibambe kahle ibhola lapho ikhanda linquma yonke indilinga yengxenye. I-point catcher iphinde imise ukuhuzuka futhi idle amabhola ensimbi ngenani elingaba ngu-0.5 kuya ku-1 pounds ngehora. Kulesi simiso, i-jet imiswa ukuhlakazwa kwamandla e-kinetic: ngemva kokuba i-jet ingene ogibeni, ihlangana nebhola lensimbi equkethwe, futhi ibhola lensimbi lijikeleza ukuze lidle amandla ejethi. Ngisho nalapho ivundlile futhi (kwezinye izimo) ibheke phansi, isibambi sendawo singasebenza.
Akuzona zonke izingxenye ze-axis ezinhlanu eziyinkimbinkimbi ngokulinganayo. Njengoba usayizi wengxenye ukhula, ukulungiswa kohlelo nokuqinisekiswa kwengxenye yendawo kanye nokunemba kokusika kuba nzima kakhulu. Izitolo eziningi zisebenzisa imishini ye-3D ukusika okulula kwe-2D nokusika kwe-3D okuyinkimbinkimbi nsuku zonke.
Ama-opharetha kufanele aqaphele ukuthi kunomehluko omkhulu phakathi kokunemba kwengxenye nokunemba kokunyakaza komshini. Ngisho nomshini onokunemba okucishe kufane, ukunyakaza okushukumisayo, ukulawula isivinini, nokuphindaphinda okuhle kakhulu ungase ungakwazi ukukhiqiza izingxenye “eziphelele”. Ukunemba kwengxenye eqediwe kuyinhlanganisela yephutha lenqubo, iphutha lomshini (ukusebenza kwe-XY) nokuzinza kwe-workpiece (ukulungiswa, ukuvuleka kanye nokuzinza kwezinga lokushisa).
Lapho usika izinto ezinobukhulu obungaphansi kwe-intshi engu-1, ukunemba kwejethi lamanzi kuvame ukuba phakathi kuka-± 0.003 kuya ku-0.015 amayintshi (0.07 kuya ku-0.4 mm). Ukunemba kwezinto eziwugqinsi kuno-1 intshi ubukhulu kungaphakathi kwamayintshi angu-±0.005 kuya ku-0.100 (0.12 kuya ku-2.5 mm). Ithebula le-XY elisebenza kahle kakhulu lenzelwe ukunemba kokuma komugqa okungamayintshi angu-0.005 noma ngaphezulu.
Amaphutha angaba khona athinta ukunemba ahlanganisa amaphutha esinxephezelo samathuluzi, amaphutha ohlelo, nokunyakaza komshini. Isinxephezelo samathuluzi ukufakwa kwenani ohlelweni lokulawula ukuze kucatshangelwe ububanzi bokusika bejethi-okungukuthi, inani lendlela yokusika okufanele yandiswe ukuze ingxenye yokugcina ithole usayizi olungile. Ukuze ugweme amaphutha angaba khona emsebenzini onembayo ephezulu, opharetha kufanele benze ukusikeka kwesivivinyo futhi baqonde ukuthi isinxephezelo samathuluzi kufanele silungiswe ukuze sihambisane nemvamisa yokugqoka kwamashubhu okuxutshwa.
Amaphutha ohlelo avamise ukwenzeka ngenxa yokuthi ezinye izilawuli ze-XY azibonisi ubukhulu kuhlelo lwengxenye, okwenza kube nzima ukuthola ukuntuleka kokumatanisa kwe-dimensional phakathi kohlelo lwengxenye nomdwebo we-CAD. Izici ezibalulekile zokunyakaza komshini ezingathula amaphutha igebe kanye nokuphindaphinda kuyunithi yomshini. Ukulungiswa kwe-Servo nakho kubalulekile, ngoba ukulungiswa kwe-servo okungalungile kungabangela amaphutha ezikhaleni, ukuphindaphinda, ukuma, nokuxoxa. Izingxenye ezincane ezinobude nobubanzi obungaphansi kwama-intshi angu-12 azidingi amatafula amaningi e-XY njengezingxenye ezinkulu, ngakho-ke amathuba okuba namaphutha okunyakaza komshini mancane.
Ama-Abrasives enza izingxenye ezimbili kwezintathu zezindleko zokusebenza zamasistimu ejethi yamanzi. Ezinye zihlanganisa amandla, amanzi, umoya, izimpawu, ama-valve okuhlola, ama-orifices, amapayipi okuxuba, izihlungi zokungena kwamanzi, nezingxenye ezisele zamaphampu asebenzisa amanzi kanye namasilinda okucindezela okuphezulu.
Ukusebenza kwamandla okugcwele kwakubonakala kubiza kakhulu ekuqaleni, kodwa ukwanda kokukhiqiza kudlule izindleko. Njengoba izinga lokugeleza kwe-abrasive likhuphuka, isivinini sokusika sizokhula futhi izindleko ziyintshi ngayinye zizokwehla zize zifike endaweni efanelekile. Ukuze uthole ukukhiqiza okuphezulu, u-opharetha kufanele aqhube inhloko yokusika ngesivinini esisheshayo kanye namandla amakhulu wehhashi ukuze asetshenziswe ngokugcwele. Uma uhlelo lwe-100-horsepower lungakwazi ukugijima ikhanda lamahhashi angu-50 kuphela, khona-ke ukusebenzisa amakhanda amabili ohlelweni kungafinyelela lokhu kusebenza kahle.
Ukuthuthukisa ukusika kwejethi yamanzi abrasive kudinga ukunakwa esimeni esithile esiseduze, kodwa kunganikeza ukukhuphuka kokukhiqiza okuhle kakhulu.
Akuhlakaniphile ukusika igebe lomoya elikhulu kuno-0.020 amayintshi ngoba indiza ivuleka esikhaleni futhi icishe inciphise amazinga aphansi. Ukunqwabelanisa amashidi abalulekile kungavimbela lokhu.
Linganisa ukukhiqiza ngokwezindleko eziyintshi ngayinye (okungukuthi, inani lezingxenye ezikhiqizwe uhlelo), hhayi izindleko ngehora. Eqinisweni, ukukhiqizwa okusheshayo kuyadingeka ukuze kuncishiswe izindleko ezingaqondile.
Amajethi amanzi avame ukubhoboza izinto eziyinhlanganisela, ingilazi, namatshe kufanele afakwe isilawuli esinganciphisa futhi sikhulise umfutho wamanzi. Usizo lwe-vacuum nobunye ubuchwepheshe bukhulisa amathuba okubhoboza ngempumelelo izinto ezithambile noma ezilayiniwe ngaphandle kokulimaza into eqondiwe.
I-automation yokubamba impahla inengqondo kuphela lapho ukuphathwa kwempahla kubala ingxenye enkulu yezindleko zokukhiqiza zezingxenye. Imishini yejet yamanzi abrasive ngokuvamile isebenzisa ukuthulula okwenziwa ngesandla, kuyilapho ukusika amapuleti kusebenzisa ngokuzenzakalelayo.
Iningi lezinhlelo zejethi zamanzi zisebenzisa amanzi kampompi ajwayelekile, kanti u-90% wabasebenzi be-waterjet awenzi noma yimaphi amalungiselelo ngaphandle kokuthambisa amanzi ngaphambi kokuthumela amanzi kusihlungi sokungena. Ukusebenzisa i-osmosis ehlehlayo nama-deionizers ukuhlanza amanzi kungase kube isilingo, kodwa ukususa ama-ion kwenza kube lula ukuthi amanzi amunce ama-ion ezinsimbi kumaphampu namapayipi anomfutho ophezulu. Inganweba impilo ye-orifice, kodwa izindleko zokushintsha isilinda sokucindezela okuphezulu, i-valve yokuhlola kanye nesembozo sokuphela ziphezulu kakhulu.
Ukusika ngaphansi kwamanzi kunciphisa isithwathwa esingaphezulu (okubuye kwaziwe ngokuthi "inkungu") onqenqemeni oluphezulu lwejethi yamanzi abrasive, kuyilapho kunciphisa kakhulu umsindo wendiza kanye nezinxushunxushu zasemsebenzini. Kodwa-ke, lokhu kunciphisa ukubonakala kwejethi, ngakho-ke kunconywa ukusebenzisa ukuqapha ukusebenza kwe-elekthronikhi ukuze kutholwe ukuchezuka ezimeni eziphakeme futhi kumise isistimu ngaphambi kwanoma yimuphi umonakalo wengxenye.
Kumasistimu asebenzisa osayizi besikrini abahlukene abahlukumezayo bemisebenzi eyahlukene, sicela usebenzise isitoreji esengeziwe kanye nokubala kosayizi abavamile. Amavalvu okulinganisa amamitha amancane (100 lb) noma amakhulu (500 kuya ku-2,000 lb) avumela ukushintsha ngokushesha phakathi kosayizi bemeshi yesikrini, kunciphise isikhathi sokuphumula kanye nobunzima, kuyilapho kukhulisa ukukhiqiza.
Isihlukanisi singakwazi ukusika izinto ngokuphumelelayo ngogqinsi olungaphansi kwamayintshi angu-0.3. Nakuba lawa ma-lugs ngokuvamile angaqinisekisa ukugaywa kwesibili kompompi, angafinyelela ukuphatha izinto ezisheshayo. Izinto eziqinile zizoba namalebula amancane.
Umshini onejethi lamanzi abrasive futhi ulawule ukujula kokusika. Ezingxenyeni ezifanele, le nqubo yokusafufusa ingase inikeze enye indlela ephoqelelayo.
I-Sunlight-Tech Inc. isebenzise izikhungo ze-GF Machining Solutions' Microlution laser micromachining kanye ne-micromilling ukuze ikhiqize izingxenye ezinokubekezelela okungaphansi kwe-micron engu-1.
Ukusika i-Waterjet kuthatha indawo emkhakheni wokukhiqiza izinto ezibonakalayo. Lesi sihloko sibheka ukuthi ama-waterjets asebenza kanjani esitolo sakho futhi sibheka inqubo.
