Ukusika i-Waterjet ingaba yindlela elula yokucubungula, kodwa ixhotyiswe ngepunch enamandla kwaye idinga ukuba umqhubi agcine ulwazi lokunxiba kunye nokuchaneka kwamacandelo amaninzi.
Ukusika ijethi yamanzi elula yinkqubo yokusika iijethi zamanzi ezinoxinzelelo oluphezulu kwizinto eziphathekayo. Le teknoloji ihlala ihambelana nobunye ubugcisa bokucubungula, obufana nokugaya, i-laser, i-EDM kunye ne-plasma. Kwinkqubo yejethi yamanzi, akukho zinto ezinobungozi okanye i-steam eyenziwe, kwaye akukho ndawo echaphazelekayo yokushisa okanye uxinzelelo lomatshini olwenziwe. Iijethi zamanzi zinokusika iinkcukacha ezi-ultra-thin kwilitye, iglasi kunye nesinyithi; ngokukhawuleza ukumba imingxuma kwi-titanium; ukutya okusikiwe; kwaye zide zibulale iintsholongwane kwiziselo nakwidiphu.
Bonke oomatshini be-waterjet banempompo enokuthi icinezele amanzi ukuba ahanjiswe kwintloko yokusika, apho iguqulwa ibe yi-supersonic flow. Kukho iintlobo ezimbini eziphambili zeempompo: iimpompo ezisekelwe kwi-drive ngqo kunye neepompo ezisekelwe kwi-booster.
Indima yempompo yokuqhuba ngokuthe ngqo ifana neyokucoca i-high-pressure cleaner, kwaye ipompo ye-cylinder emithathu iqhuba i-plunger ezintathu ngqo kwi-motor yombane. Uxinzelelo oluphezulu oluqhubekayo lokusebenza luyi-10% ukuya kwi-25% ephantsi kuneempompo ze-booster ezifanayo, kodwa oku kusabagcina phakathi kwe-20,000 kunye ne-50,000 psi.
Iimpompo ezisekelwe kwi-intensifier zenza uninzi lweempompo zoxinzelelo oluphezulu (oko kukuthi, iimpompo ezingaphezu kwe-30,000 psi). Ezi mpompo ziqulethe iisekethe ezimbini zolwelo, enye yeyamanzi kwaye enye yeye-hydraulics. Isihluzo sokungena kwamanzi kuqala sidlula kwi-1 micron cartridge filter kwaye emva koko i-0.45 micron yokucoca ukufunxa kumanzi etephu eqhelekileyo. La manzi angena kwimpompo yokukhuthaza. Ngaphambi kokuba ingene kwipompo ye-booster, uxinzelelo lwempompo ye-booster igcinwa malunga ne-90 psi. Apha, uxinzelelo lonyuswe kwi-60,000 psi. Phambi kokuba amanzi ekugqibeleni ayishiye iseti yempompo aze afikelele kwintloko yokusika ngombhobho, amanzi adlula kwisixhobo sokufunxa ukothuka. Isixhobo sinokucinezela ukuguquguquka koxinzelelo ukuphucula ukuhambelana kunye nokuphelisa i-pulses eshiya amanqaku kwi-workpiece.
Kwisekethe ye-hydraulic, imotor yombane phakathi kweenjini zombane itsala ioyile kwitanki yeoli kwaye iyicinezele. Ioyile ecinezelekileyo iqukuqela iye kwi-manifold, kwaye ivalve ye-manifold ngokutshintshanayo ifaka ioyile yehydraulic kumacala omabini ebhiskithi kunye nendibano yeplunger ukuvelisa isenzo sokubetha kwe-booster. Ekubeni umphezulu we-plunger uncinci kune-biscuit, uxinzelelo lweoli "luphucula" uxinzelelo lwamanzi.
I-booster yimpompo ebuyiselayo, oku kuthetha ukuba i-biscuit kunye ne-plunger assembly ihambisa amanzi aphezulu ukusuka kwelinye icala le-booster, ngelixa i-low-pressure water igcwalisa elinye icala. Ukuphinda kujikelezwe kwakhona kuvumela ioyile yehydraulic ukuba iphole xa ibuyela kwitanki. I-valve yokukhangela iqinisekisa ukuba i-low-pressure kunye ne-high-pressure yamanzi inokuhamba kuphela kwicala elinye. Iisilinda zoxinzelelo oluphezulu kunye nee-end caps ezibandakanya i-plunger kunye ne-biscuit components kufuneka zihlangabezane neemfuno ezikhethekileyo zokumelana nemikhosi yenkqubo kunye nemijikelezo yoxinzelelo oluqhubekayo. Yonke inkqubo yenzelwe ukuba ingaphumeleli ngokuthe ngcembe, kwaye ukuvuza kuya kuqukuqela "kwimingxuma yokucoca" ekhethekileyo, enokuthi ibekwe iliso ngumqhubi ukuze kucwangciswe ngcono ukugcinwa rhoqo.
Umbhobho okhethekileyo woxinzelelo oluphezulu uhambisa amanzi kwintloko yokusika. Umbhobho unokubonelela ngokukhululeka kokuhamba kwentloko yokusika, kuxhomekeke kubukhulu bombhobho. Insimbi engenasici yinto ekhethiweyo yale mibhobho, kwaye kukho ubungakanani obuthathu obuqhelekileyo. Imibhobho yensimbi enobubanzi be-1/4 intshi iguquguquka ngokwaneleyo ukudibanisa nezixhobo zemidlalo, kodwa ayikhuthazwa ukuthuthwa komgama omde wamanzi aphezulu. Ekubeni le ityhubhu kulula ukugoba, nakwi-roll, ubude be-10 ukuya kwi-20 yeenyawo inokufezekisa i-X, Y, kunye ne-Z motion. Imibhobho emikhulu ye-3/8-intshi i-3/8-intshi idla ngokuthwala amanzi ukusuka kumpompo ukuya ezantsi kwezixhobo ezihambayo. Nangona inokugotywa, ayifanelekanga ngokubanzi kwisixhobo sokushukuma sombhobho. Umbhobho omkhulu, umlinganiselo we-9/16 intshi, ungcono kakhulu ukuthutha amanzi anoxinzelelo oluphezulu kumgama omde. I-diameter enkulu inceda ukunciphisa ilahleko yoxinzelelo. Imibhobho yolu bukhulu ihambelana kakhulu neempompo ezinkulu, kuba umthamo omkhulu wamanzi aphezulu oxinzelelo nawo unomngcipheko omkhulu wokulahlekelwa kwengcinezelo. Nangona kunjalo, imibhobho yolu bukhulu ayikwazi ukugoba, kwaye ukufakwa kufuneka kufakwe kwiikona.
Umatshini wokusika ijethi yamanzi acocekileyo ngowona matshini wokuqala wokusika ijethi yamanzi, kwaye imbali yayo inokulandelwa emva kwe1970s yokuqala. Xa kuthelekiswa noqhagamshelwano okanye inhalation yezinto eziphathekayo, zivelisa amanzi amancinci kwizinto eziphathekayo, ngoko zifanelekile ukuveliswa kweemveliso ezifana neenqwelo zangaphakathi kunye ne-diapers ezilahlayo. Ulwelo lubhityile kakhulu-i-intshi ze-0.004 ukuya kwi-intshi ye-0.010 ububanzi-kwaye lubonelela ngeejiyometri ezineenkcukacha ezininzi kunye nelahleko encinci kakhulu. Amandla okusika aphantsi kakhulu, kwaye ukulungiswa ngokuqhelekileyo kulula. Aba matshini bafaneleke kakhulu ukusebenza iiyure ezingama-24.
Xa uqwalasela intloko yokusika umatshini ococekileyo wamanzi, kubalulekile ukukhumbula ukuba ukuhamba kwesantya ngamaqhekeza amancinci okanye amaqhekeza ezinto zokukrazula, kungekhona uxinzelelo. Ukufezekisa esi santya siphezulu, amanzi acinezelekileyo ahamba ngomngxuma omncinci kwigem (ngokuqhelekileyo isafire, irubhi okanye idayimane) emiswe ekupheleni komlomo. Ukusika okuqhelekileyo kusebenzisa i-orifice diameter ye-intshi ye-0.004 ukuya kwi-intshi ye-0.010, ngelixa izicelo ezikhethekileyo (ezifana nekhonkrithi etshisiweyo) zingasebenzisa ubukhulu ukuya kwi-intshi ye-0.10. Kwi-40,000 psi, ukuhamba okuvela kwi-orifice kuhamba ngesantya esimalunga ne-Mach 2, kunye ne-60,000 psi, ukuhamba kudlula i-Mach 3.
Ubucwebe obuhlukeneyo bunobuchule obuhlukeneyo bokusika i-waterjet. ISapphire yeyona nto ixhaphakileyo yenjongo jikelele. Zihlala malunga ne-50 ukuya kwiiyure ze-100 zexesha lokusika, nangona i-abrasive waterjet isicelo se-half la maxesha. Iirubhi azifanelekanga ukusika ijet yamanzi ecocekileyo, kodwa ukuhamba kwamanzi abavelisayo kukulungele kakhulu ukusika i-abrasive. Kwinkqubo yokusika i-abrasive, ixesha lokusika i-rubi li malunga ne-50 ukuya kwiiyure ze-100. Iidayimani zibiza kakhulu kunesafire kunye neerubhi, kodwa ixesha lokusika liphakathi kwe-800 kunye ne-2,000 iiyure. Oku kwenza idayimani ifaneleke ngokukodwa ukusebenza kweeyure ezingama-24. Kwezinye iimeko, i-diamond orifice nayo inokucocwa nge-ultrasonically kwaye isetyenziswe kwakhona.
Kumatshini we-waterjet abrasive, indlela yokukhutshwa kwezinto eziphathekayo ayikho ukuhamba kwamanzi ngokwawo. Ngokwahlukileyo koko, ukuhamba kukhawulezisa amaqhekeza abrasive ukugqwala izinto. Aba matshini bangamawaka amaxesha anamandla ngakumbi kunoomatshini bokusika bejet ecocekileyo, kwaye banokusika izinto ezinzima njengentsimbi, ilitye, izinto ezidibeneyo kunye neekeramics.
Umjelo we-abrasive mkhulu kunomlambo wejethi wamanzi acocekileyo, kunye nobubanzi obuphakathi kwe-0.020 intshi kunye ne-0.050 intshi. Bangakwazi ukusika izitaki kunye nezixhobo ukuya kwi-intshi ezili-10 ubukhulu ngaphandle kokudala iindawo ezichaphazelekayo kubushushu okanye uxinzelelo lomatshini. Nangona amandla abo anyukile, amandla okusika umjelo we-abrasive usengaphantsi kweponti enye. Phantse yonke imisebenzi ye-jetting ye-abrasive isebenzisa i-jetting device, kwaye inokutshintsha ngokulula ukusuka kwi-single-headset ukuya kwi-multi-head-head, kwaye i-jet yamanzi e-abrasive inokuguqulwa ibe yijethi yamanzi ecocekileyo.
I-abrasive ilukhuni, ikhethiweyo ngokukhethekileyo kunye nobukhulu besanti-ngokuqhelekileyo igarnet. Iisayizi ezahlukeneyo zegridi zifanelekile kwimisebenzi eyahlukeneyo. Umphezulu ogudileyo unokufumaneka nge-120 ye-mesh abrasives, ngelixa i-80 ye-mesh abrasives ibonakalise ukuba ifaneleke ngakumbi kwizicelo zenjongo jikelele. Isantya sokusika se-mesh engama-50 siyakhawuleza, kodwa umphezulu urhabaxa kancinci.
Nangona iijethi zamanzi zilula ukusebenza kunabanye oomatshini abaninzi, ityhubhu yokuxuba ifuna ingqalelo yomsebenzisi. Amandla okukhawulezisa ale tyhubhu afana nebhere yompu, enobukhulu obahlukeneyo kunye nobomi obutshintshileyo. I-tube yokuxuba ehlala ixesha elide i-revolutionary innovation kwi-abrasive water jet cutting, kodwa ityhubhu isenobuthathaka kakhulu-ukuba intloko yokusika idibana ne-fixture, into enzima, okanye into ekujoliswe kuyo, ityhubhu inokugqabhuka. Imibhobho eyonakeleyo ayinakulungiswa, ngoko ke ukugcina iindleko ziphantsi kufuna ukunciphisa ukutshintshwa. Oomatshini banamhlanje ngokuqhelekileyo banomsebenzi wokufumanisa ukungqubana okuzenzekelayo ukukhusela ukungqubana nombhobho wokuxuba.
Umgama wokuhlukana phakathi kombhobho wokuxuba kunye nezinto ezijoliswe kuzo ngokuqhelekileyo ziyi-0.010 intshi ukuya kwi-intshi ye-0.200, kodwa umqhubi kufuneka akhumbule ukuba ukwahlukana okukhulu kune-intshi ye-0.080 kuya kubangela i-frosting phezulu kwi-cut cut of the part. Ukusika ngaphantsi kwamanzi kunye nobunye ubuchule bunokunciphisa okanye buphelise le qabaka.
Ekuqaleni, ityhubhu yokuxuba yenziwe nge-tungsten carbide kwaye yayinobomi benkonzo kuphela kwiiyure ezine ukuya ezintandathu zokusika. Imibhobho ehlanganisiweyo yanamhlanje enexabiso eliphantsi inokufikelela kubomi bokusika kwiiyure ezingama-35 ukuya kwezingama-60 kwaye iyacetyiswa ngokusikwa ngokurhabaxa okanye ukuqeqesha abaqhubi abatsha. I-tube ye-carbide ene-cemented cemented yandisa ubomi bayo benkonzo kwi-80 kwiiyure ze-90 zokusika. I-tube ye-carbide edibeneyo ekumgangatho ophezulu inobomi bokusika i-100 kwiiyure ze-150, ifanelekile ukuchaneka kunye nomsebenzi wemihla ngemihla, kwaye ibonisa eyona nto iqikelelwayo yokugqoka i-concentric.
Ukongeza kokubonelela ngentshukumo, izixhobo zomatshini we-waterjet kufuneka zibandakanye indlela yokukhusela i-workpiece kunye nenkqubo yokuqokelela kunye nokuqokelela amanzi kunye ne-debris kwi-machining operations.
Oomatshini abamileyo kunye nomgangatho omnye zezona zilula zamanzi. Iijethi zamanzi ezimileyo ziqhele ukusetyenziswa kwindawo ye-aerospace ukucheba imathiriyeli edibeneyo. Umsebenzisi wondla izinto emlanjeni njengesarha yebhendi, ngelixa umbambisi eqokelela umlambo kunye nobutyobo. Uninzi lweejethi zamanzi ezimileyo ziijethi zamanzi ezicocekileyo, kodwa ayizizo zonke. Umatshini wokuqhawula umatshini uhlukile kumatshini omileyo, apho iimveliso ezifana nephepha zondliwa ngomatshini, kwaye ijethi yamanzi inqumla imveliso ibe ububanzi obuthile. Umatshini wokunqumla umatshini ngumatshini ohamba ecaleni kwe-axis. Bahlala besebenza kunye noomatshini bokusika ukwenza iipateni ezinjengegridi kwiimveliso ezinje ngoomatshini bokuthengisa abanje ngebrownies. Umatshini wokusika usika imveliso ibe ububanzi obuthile, ngelixa umatshini wokunqumla umatshini unqumla imveliso eyondliwe ngaphantsi kwayo.
Abaqhubi akufuneki basebenzise ngesandla olu hlobo lwejethi yamanzi abrasive. Kunzima ukuhambisa into esikiweyo ngesantya esikhethekileyo nesihambelanayo, kwaye kuyingozi kakhulu. Abavelisi abaninzi abayi kucaphula oomatshini kwezi setingi.
Itheyibhile ye-XY, ebizwa ngokuba ngumatshini wokusika i-flatbed, ngowona matshini uqhelekileyo wokusika ijet yamanzi. Iijethi zamanzi ezicocekileyo zisika iigaskets, iiplastiki, irabha kunye nogwebu, ngoxa iimodeli ezirhabaxa zisika isinyithi, imidibaniso, iglasi, amatye kunye neeseramikhi. Ibhentshi yokusebenzela ingaba encinci njenge-2 × 4 iinyawo okanye inkulu njenge-30 × 100 iinyawo. Ngokuqhelekileyo, ulawulo lwezi zixhobo zoomatshini luphathwa yi-CNC okanye iPC. Iinjini zeServo, zihlala zinempendulo evaliweyo, ziqinisekisa ukuthembeka kwesikhundla kunye nesantya. Iyunithi esisiseko ibandakanya izikhokelo zomgca, izindlu zokuthwala kunye ne-ball screw drives, ngelixa iyunithi yebhulorho iquka ezi teknoloji, kunye netanki yokuqokelela iquka inkxaso yezinto eziphathekayo.
Iibhentshi ze-XY zihlala zihamba ngeendlela ezimbini: i-middle-rail gantry workbench ibandakanya iileyili ezimbini zesikhokelo kunye nebhuloho, ngelixa i-workbench ye-cantilever isebenzisa isiseko kunye nebhuloho eqinile. Zombini iintlobo zomatshini ziquka uhlobo oluthile lokulungiswa kokuphakama kwentloko. Olu lungelelaniso lwe-Z-axis lungathatha imo ye-crank manual, i-screw yombane, okanye isikrufu se-servo esicwangciswe ngokupheleleyo.
I-sump kwi-workbench ye-XY idla ngokuba yitanki yamanzi ezaliswe ngamanzi, exhotywe ngeegrille okanye i-slats ukuxhasa i-workpiece. Inkqubo yokusika idla ezi zixhaso kancinci. Umgibe unokucocwa ngokuzenzekelayo, inkunkuma igcinwe kwi-container, okanye ingaba yincwadana, kwaye umqhubi uhlala ehlambulula i-can.
Njengoko umyinge wezinto eziphantse zingabikho iindawo ezisicaba zisanda, izakhono ezi-axis ezintlanu (okanye ngaphezulu) ziyimfuneko kwi-waterjet cutting yanamhlanje. Ngethamsanqa, intloko yokusika i-lightweight kunye ne-low recoil force ngexesha lenkqubo yokusika inika iinjineli zoyilo ngenkululeko engenalo umthwalo ophezulu. Ukusika ijet yejet ye-five-axis ekuqaleni kusetyenziswa inkqubo yetemplate, kodwa abasebenzisi bakhawuleza bajikela kwi-programmable five-axis ukulahla iindleko zetemplate.
Nangona kunjalo, kunye nesoftware ezinikeleyo, ukusika kwe-3D kunzima ngakumbi kune-2D yokusika. Inxalenye yomsila odibeneyo weBoeing 777 ngumzekelo ogqithisileyo. Okokuqala, umqhubi ulayisha inkqubo kunye neenkqubo zabasebenzi abaguquguqukayo "pogostick". I-crane ephezulu ihambisa izinto eziphathekayo zamacandelo, kwaye i-spring bar ayinqunywanga ekuphakameni okufanelekileyo kwaye iinxalenye zilungisiwe. I-axis ye-Z ekhethekileyo engasikwanga isebenzisa i-probe yoqhagamshelwano ukuze ibeke ngokuchanekileyo indawo kwindawo, kunye namanqaku esampula ukufumana indawo echanekileyo yokuphakama kunye nolwalathiso. Emva koko, inkqubo iphinda iqondiswe kwindawo eyiyo yenxalenye; i-probe ihlehlisa ukwenza indawo ye-Z-axis yentloko yokusika; Inkqubo iqhuba ukulawula zonke ii-axes ezintlanu ukugcina intloko yokusika i-perpendicular kumphezulu ukuze inqunywe, kwaye isebenze njengoko kuyimfuneko Ukuhamba ngesantya esichanekileyo.
I-Abrasives iyadingeka ukusika izinto ezidibeneyo okanye nayiphi na isinyithi esikhulu kune-intshi ye-0.05, oku kuthetha ukuba i-ejector idinga ukuvinjelwa ukusika ibha yasentwasahlobo kunye nebhedi yesixhobo emva kokusika. Ukuthathwa kwamanqaku akhethekileyo yindlela efanelekileyo yokufezekisa i-five-axis waterjet cutting. Uvavanyo lubonise ukuba obu buchwepheshe bunokumisa inqwelomoya yejethi enamandla angama-50 ngaphantsi kwee-intshi ezi-6. Isakhelo esimise okwe-C sidibanisa isibambisi kwisihlahla se-Z-axis ukuze sigange ngokuchanekileyo ibhola xa intloko icheba yonke isangqa senxalenye. I-point catcher iphinda iyeke i-abrasion kwaye idle iibhola zetsimbi ngesantya malunga ne-0.5 ukuya kwi-1 pound ngeyure. Kule nkqubo, i-jet imisiwe ngokusasazwa kwamandla e-kinetic: emva kokuba i-jet ingene emgibeni, idibana nebhola yensimbi equlethwe, kwaye ibhola yensimbi ijikeleza ukuze idle amandla ejethi. Nokuba ithe tye kwaye (kwezinye iimeko) ijonge phantsi, indawo yokubambisa inokusebenza.
Ayizizo zonke iinxalenye ze-axis ezintlanu zintsonkothe ngokulinganayo. Njengoko ubungakanani benxalenye bukhula, ukulungiswa kweprogram kunye nokuqinisekiswa kwendawo yecandelo kunye nokuchaneka kokusika kuba nzima ngakumbi. Iivenkile ezininzi zisebenzisa oomatshini be-3D ukusika okulula kwe-2D kunye nokusika okuntsonkothileyo kwe-3D yonke imihla.
Abaqhubi kufuneka baqonde ukuba kukho umahluko omkhulu phakathi kokuchaneka kwenxalenye kunye nokuchaneka kwentshukumo yomatshini. Kwanomatshini onokuchaneka ngokugqibeleleyo, intshukumo eguqukayo, ulawulo lwesantya, kunye nokuphindaphinda okugqwesileyo unokungakwazi ukuvelisa iindawo “ezigqibeleleyo”. Ukuchaneka kwenxalenye egqityiweyo kukudityaniswa kwephutha lenkqubo, impazamo yomatshini (ukusebenza kwe-XY) kunye nokuzinza kwe-workpiece (ukulungiswa, ukucwangciswa kunye nokuzinza kweqondo lokushisa).
Xa ukusika izinto ezinobunzima obungaphantsi kwe-intshi ye-1, ukuchaneka kwejethi yamanzi ngokuqhelekileyo phakathi kwe-± 0.003 ukuya kwi-0.015 intshi (0.07 ukuya kwi-0.4 mm). Ukuchaneka kwezinto ezingaphezulu kwe-intshi eyi-1 ubukhulu kungaphakathi kwe-± 0.005 ukuya kwi-0.100 intshi (0.12 ukuya kwi-2.5 mm). Itheyibhile ye-XY ephezulu yenzelwe ukuchaneka komgca we-0.005 intshi okanye ngaphezulu.
Iimpazamo ezinokwenzeka ezichaphazela ukuchaneka ziquka iimpazamo zembuyekezo yesixhobo, iimpazamo zeprogram, kunye nokunyakaza komatshini. Imbuyekezo yesixhobo yigalelo lexabiso kwinkqubo yokulawula ukuba ithathele ingqalelo ububanzi bokusika i-jet-oko kukuthi, inani lendlela yokusika ekufuneka yandiswe ukuze inxalenye yokugqibela ifumane ubungakanani obuchanekileyo. Ukuze ugweme iimpazamo ezinokwenzeka kumsebenzi ochanekileyo, abaqhubi kufuneka benze ukucuthwa kwezilingo kwaye baqonde ukuba imbuyekezo yesixhobo kufuneka ilungiswe ukuze ihambelane nobuninzi bokugqoka i-tube yokuxuba.
Iimpazamo zeprogramu zihlala zisenzeka ngenxa yokuba ezinye izilawuli ze-XY azibonisi imilinganiselo kwiprogram yecandelo, okwenza kube nzima ukubona ukungabikho kokulinganisa okuphakathi kweprogram yecandelo kunye nomzobo weCAD. Imiba ebalulekileyo yokunyakaza komatshini onokuzisa iimpazamo yi-gap kunye nokuphindaphinda kwiyunithi yomatshini. Uhlengahlengiso lwe-Servo lukwabalulekile, kuba uhlengahlengiso olungafanelekanga lwe-servo lunokubangela iimpazamo kwizithuba, ukuphinda-phinda, ukuma nkqo, kunye nencoko. Amalungu amancinci anobude kunye nobubanzi obungaphantsi kwee-intshi ezili-12 ayifuni iitafile ezininzi ze-XY njengeenxalenye ezinkulu, ngoko ke ukubakho kweempazamo zokunyakaza komatshini kuncinci.
Iingxelo ze-Abrasives zesibini kwisithathu seendleko zokusebenza kweenkqubo zejet zamanzi. Ezinye ziquka amandla, amanzi, umoya, izitywina, iivalve zokujonga, ii-orifices, imibhobho yokuxuba, izihlungi zokungena kwamanzi, kunye neendawo ezisecaleni kwiimpompo ze-hydraulic kunye ne-high-pressure cylinders.
Ukusebenza kwamandla apheleleyo kwabonakala kubiza kakhulu ekuqaleni, kodwa ukunyuka kwemveliso kugqithise iindleko. Njengoko isantya sokuhamba kwe-abrasive sinyuka, isantya sokusika siya kunyuka kwaye iindleko nge-intshi nganye ziya kuncipha de zifike kwindawo efanelekileyo. Ukufumana imveliso ephezulu, umqhubi kufuneka aqhube intloko yokusika ngesantya esikhawulezayo sokusika kunye namandla aphezulu ehashe ukuze asetyenziswe ngokufanelekileyo. Ukuba inkqubo ye-horsepower ye-100 inokuqhuba kuphela intloko ye-horsepower engama-50, emva koko ukuqhuba iintloko ezimbini kwinkqubo inokufezekisa le mpumelelo.
Ukuphucula ukusika kwejethi yamanzi kufuna ingqalelo kwimeko ethile, kodwa kunokubonelela ngemveliso ebalaseleyo.
Ayibobulumko ukusika isithuba somoya esikhulu kune-intshizi eziyi-0.020 kuba ijethi ivula kwisithuba kwaye isika ngokurhabaxa amanqanaba asezantsi. Ukuhlanganisa amaxwebhu ezinto eziphathekayo ngokusondeleyo kunokuthintela oku.
Ukulinganisa imveliso ngokwexabiso le-intshi nganye (oko kukuthi, inani lamalungu enziwe yinkqubo), hayi iindleko ngeyure. Enyanisweni, imveliso ekhawulezayo iyimfuneko ukuze uhlawule iindleko ezingathanga ngqo.
Iijethi zamanzi ezihlala zigqobhoza izinto eziyintlanganisela, iglasi, namatye kufuneka zixhotyiswe ngesilawuli esinokunciphisa nokunyusa uxinzelelo lwamanzi. Uncedo lwe-vacuum kunye nobunye ubuchwepheshe bonyusa amathuba okugqobhoza ngempumelelo izinto ezibuthathaka okanye ezilamiweyo ngaphandle kokonakalisa imathiriyeli ekujoliswe kuyo.
I-automation yokuphatha izinto eziphathekayo inengqiqo kuphela xa i-akhawunti yokuphatha izinto eziphathekayo inxalenye enkulu yeendleko zemveliso yamacandelo. Oomatshini bejet ye-Abrasive waterjet bavame ukusebenzisa ukukhulula ngesandla, ngelixa ukusika ipleyiti ikakhulu kusebenzisa i-automation.
Uninzi lweenkqubo zejet zamanzi zisebenzisa amanzi ompompo aqhelekileyo, kwaye i-90% yabasebenzisi bejet awenzi nawaphi na amalungiselelo ngaphandle kokuthambisa amanzi phambi kokuthumela amanzi kwisihluzo sokungena. Ukusebenzisa i-osmosis eguqukayo kunye ne-deionizers ukucoca amanzi kusenokuhenda, kodwa ukususa ii-ion kwenza kube lula ukuba amanzi afunxe ii-ion kwiintsimbi kwiimpompo kunye nemibhobho yoxinzelelo oluphezulu. Inokwandisa ubomi be-orifice, kodwa iindleko zokutshintsha i-cylinder yoxinzelelo oluphezulu, i-valve yokukhangela kunye ne-cover cover iphezulu kakhulu.
Ukusika ngaphantsi kwamanzi kunciphisa i-frosting ebusweni (ekwaziwa ngokuba "yinkungu") kumda ongaphezulu we-abrasive waterjet cutting, ngelixa unciphisa kakhulu ingxolo yejethi kunye nesiphithiphithi somsebenzi.
