Umshini wokumunca isihlabathi se-vacuum (owaziwa nangokuthi umshini we-vacuum sandblasting, umshini{0}}we-sandblasting wamahhala, kanye nomshini wokugaywa kabusha kwe-sandblasting) uyisisetshenziswa esisebenza kahle futhi esivumelana nemvelo. Ihlanganisa ukuhlanzwa kwe-sandblasting nokululama okulimazayo nokuhlukanisa uthuli, kwenze isistimu yokujikeleza evaliwe noma ecishe ivalwe{2}. Okulandelayo ukuhlaziya okuningiliziwe kwezici zayo zokusebenza namathiphu ohlelo lwakho lokusebenza.
I. Izici Zokusebenza Eziyinhloko Zomshini Wokudonsa Isihlabathi Sevacuum
1. Izinzuzo eziyinhloko zomshini wokumunca isihlabathi se-vacuum
Uthuli{{0}olungenalo uthuli futhi aluhambisani nemvelo: Isici esivelele kakhulu. Ngohlelo lokutakula i-vacuum, izinto eziqhumayo nezintuli ezikhiqiziwe zimuncwa ngokushesha, cishe alukho uthuli oluphumayo. Indawo yokusebenza ihlanzekile futhi ihlangabezana nezidingo zokuvikela imvelo.
Umjikelezo-wokuphinda usebenzise kahle kakhulu: Ifakwe isihlukanisi nesihlungi sangaphakathi, ingahlukanisa ama-abrasive atholakalayo othulini. Ama-abrasive ahlanzekile abuyiselwa ohlelweni ukuze agaywe kabusha, kunciphisa kakhulu izindleko zokusebenzisa ama-abrasive.
Iselula futhi iyavumelana nezimo: Imvamisa yakhelwe njengohlobo oluphathekayo noma lwetroli, ayidingi ukwakhiwa kwamashedi ayinkimbinkimbi futhi ifaneleka ngokukhethekile ukucutshungulwa kwendawo,{0}}ekwakhiweni kwesayithi,{1}}ukusebenza kokuphakama okuphezulu nezinye izimo.
Ukucutshungulwa kwephoyinti{0}}okunembayo okuqondile: Ikhanda lesibhamu sokufuthwa lifakwe iringi yokuvala injoloba, enganamathela eduze kwendawo yokusebenza ukuze yakhe indawo yokucindezela engalungile, izuze ukuhlanzwa okunembile ngaphandle kokuthinta indawo ezungezile.
Ukonga izindleko: Ukugaywa kabusha kwama-abrasive kunciphisa izindleko zezinto ezisebenzisekayo kanye nokulahlwa kwezinto ezihuga udoti.
2. Ukulinganiselwa kwezobuchwepheshe
Ukusebenza kahle kokucubungula: Uma kuqhathaniswa nemishini emikhulu evulekile-yesikali se-sandblasting, ukusebenza kahle kwayo{1}}kwephuzu elilodwa okuqhubekayo kuphansi uma kuqhathaniswa, okuyenza ifaneleke kakhulu ezindaweni-ezinosayizi omaphakathi noma ukucutshungulwa okuhle.
Ubulukhuni bobuso: Njengoba umsebenzi wenziwa endaweni ye-vacuum, amandla omthelela womjovo oqhumayo ngezinye izikhathi abe ngaphansi kancane kunalowo womjovo oqondile ovulekile. Kuzinhlelo zokusebenza ezidinga ubulukhuni obuphezulu kakhulu, ukuhlolwa nokuqinisekiswa kuyadingeka.
Ubunkimbinkimbi bezinsimbi: Inezinhlelo zokugaywa kabusha kwangaphakathi, ukuhlukanisa kanye nokuhlunga, futhi izidingo zokunakekelwa ziphakeme uma kuqhathaniswa.
Ukutshalwa kwezimali kokuqala: Iyunithi yenani lentengo yezinto zokusebenza ngokuvamile iba phezulu kunaleyo yemishini yokuqhumisa isihlabathi evulekile evamile.
3. Imingcele yokusebenza ebalulekile yomshini wokumunca isihlabathi se-vacuum
Idigri ye-vacuum kanye nesilinganiso sokugeleza: Thola amandla e-adsorption namandla okubuyisela.
Umthamo wethangi le-abrasive: Kuthinta isikhathi sokusebenza okuqhubekayo.
Ukusebenza kahle kwesistimu yokuhlukanisa: Inquma inani lezikhathi lapho i-abrasive ingaphinda igaywe kabusha kanye nokuhlanzeka komoya wokugcina okhishiwe.
I-nozzle kanye nobubanzi: Imibhobho ye-Boron carbide/tungsten carbide ayigugi-iyamelana, futhi ububanzi buthinta isivinini sokuhlanza kanye nokuba mahhadlahhadla.
Ii. Izinkambu Zokusebenza Zemishini Yokudonsa Isihlabathi Sevacuum
Izici "ezingenalutho-ezingenalo uthuli" kanye "noziphathekayo" zomshini wokumunca isihlabathi se-vacuum zikwenza kungenakushintshwa kulezi zindawo ezilandelayo:
Ukulungisa nokulungisa
Imikhumbi nezinkundla ezingasogwini: Ukususwa kokugqwala kwasendaweni kanye nokuhlanzwa kobuhlalu bokushisela kwamadekhi, amakhebhini nama-hulls.
Amathangi esitoreji namapayipi: Ukulungiswa kodonga lwangaphakathi -ku-corrosion, ukwelashwa kwe-pitting corrosion, ikakhulukazi okufanele -kuzinto zesevisi.
Amabhuloho nezakhiwo zensimbi: Ukushintsha{0}}i-corrosion coating yendawo enomthelela omncane ezimotweni nabahamba ngezinyawo.
Ukukhiqiza Nokunemba Machining
Ukuhlanzwa kwe-weld seam: Susa isikali se-slag ne-oxide ukuze ulungiselele-ukuhlola okungonakalisi (okufana ne-PT, MT).
Ukwelashwa kwangaphambili komhlaba: Ukwelashwa okuqinile ngaphambi kokuthintwa kwendawo-ukudweba phezulu ukuze kuthuthukiswe ukunamathela kwe-coating.
Ukuhlanza isikhunta: Khipha izinsalela endaweni yokubunjwa komjovo bese uyafa-isikhunta sokuphonsa.
Ukuqothula kanye nokususwa kwe-flash: Ukuqedela ukukhishwa kwensimbi encane kanye nezingxenye ezenziwe ngomshini.
Ezokwakha kanye Nokuvikela Amagugu Ezamasiko
Ukuhlanza amatshe nokhonkolo: Susa ukungcola, izendlalelo ezinesimo sezulu esishisayo, nezimbotshana ezindala ngaphandle kokulimaza isisekelo.
Ukubuyiselwa kwezakhiwo zasendulo: Ukususwa okunembile kwemikhiqizo egqwalile endaweni yezitini, amatshe nezingxenye zensimbi, ngokulawula okuhle kakhulu.
I-Aerospace
Ukulungisa izinto ezihlanganisiwe: Yenza ukunakekelwa kwe-lamination surface elawulekayo endaweni eyonakele.
Ukuhlanzwa kwengxenye yenjini: Susa amadiphozithi ekhabhoni nezimbotshana ezingxenyeni ezinjengama-turbine blades.
Isifinyezo
Umshini wokumunca isihlabathi se-vacuum ungummeleli ojwayelekile wokuthuthukiswa kobuchwepheshe bokwelapha okungaphezulu ekuvikelweni kwemvelo kanye nokucwengwa. Akuhloselwe ukufaka esikhundleni ngokuphelele i-sandblasting yendabuko, kodwa kunalokho isisombululo esihle kakhulu ezimeni lapho kunezidingo eziphezulu zokulawula uthuli, ukuguquguquka kokwakhiwa nokunemba.
Imfihlo yokusebenzisa umshini wokumunca isihlabathi se-vacuum ilele kulokhu: ukukhetha i-abrasive efanele ngokusekelwe ezintweni eziwucezu lokusebenza kanye nezidingo zokucubungula, ukulandela ngokuqinile imithethonqubo yokunakekela ukugcina okokusebenza kusesimweni esingcono kakhulu, nokuqinisekisa umphumela wokucubungula nokusebenza kahle ngokusebenzisa amasu okusebenza ahlakaniphile (ukunamathela, ukunyakaza, ukubuka).
