Umshini wokuqhumisa i-Junda Sandblasting kanye nomshini wokuhlikihla i-Junda shot peening kuyimishini emibili ehlukene. Nakuba igama lifana, kunomehluko omkhulu ekusetshenzisweni. Kodwa-ke, ukuze kugwenywe iphutha lokukhetha komsebenzisi, kuthinte ukusetshenziswa futhi kubangele ukumoshwa kwezindleko, umehluko ohambisanayo wethulwa ngokulandelayo.
1, umehluko phakathi kokudubula nokuqhuma kwesihlabathi
Umgomo wokuhlanza ngesibhamu kanye nokuqhumisa ngesanti uyindlela yokuhlanza ubuso bomkhiqizo usebenzisa umoya njengamandla. Ukuhlanza ngesibhamu kusebenzisa insimbi ebhulashayo, njengensimbi ebhulashayo, isihlabathi sensimbi, i-ceramic shot. Ukuqhumisa ngesanti kusetshenziswa izinto ezibhulashayo ezingezona ezensimbi, njengesihlabathi se-corundum, isihlabathi sengilazi, isihlabathi se-resin njalo njalo.
2, inqubo yokuqhuma kwesibhamu sikaJunda kanye nokuqhuma kwesihlabathi
Inqubo yokuchama ngesibhamu kanye nokuqhumisa isihlabathi isekelwe emikhiqizweni ehlukene, ukusebenza kanye nezinye izidingo zokunquma ukuthi kufanele kusetshenziswe ukuchama ngesibhamu noma ukuqhumisa isihlabathi.
3. Ukukhethwa kwemishini yokudubula kanye neyokuqhumisa isihlabathi
Ukuchama ngesibhamu kanye nokuqhumisa isihlabathi ngaphezu kokuhluza, ukubuyisa okuhluza, idivayisi yokuhlunga okuhluza ihlukile, amanye amadivayisi emishini afana, vele, izinhlayiya ezincane zokuhluza nazo zingaba ezijwayelekile futhi imishini yokuqhumisa isihlabathi, vele, incike esimweni sangempela.
4. Ukuhlikihla ngesibhamu kuyindlela yokususa ukugqwala kwensimbi ngokusebenzisa umoya ocindezelwe noma amandla e-centrifugal omshini njengamandla kanye nokungqubuzana. Ububanzi be-projectile buphakathi kuka-0.2-2.5mm, umfutho womoya ocindezelwe ungu-0.2-0.6mpa, kanti i-Engela ephakathi kwejethi kanye nobuso ingama-degrees angaba ngu-30-90. Ama-nozzle enziwe ngensimbi yamathuluzi engu-T7 noma i-T8 futhi aqiniswe abe lukhuni lwama-degrees angu-50. Impilo yenkonzo ye-nozzle ngayinye iyizinsuku ezingu-15-20. Ukuhlikihla ngesibhamu kusetshenziselwa ukususa isikali, ukugqwala, isihlabathi sokubumba kanye nefilimu yopende endala emikhiqizweni yensimbi ephakathi nenkulu enobukhulu obungaphansi kuka-2mm noma izingxenye zokufaka nokufaka ezingadingi usayizi onembile kanye nokwakheka. Kuyindlela yokuhlanza ngaphambi kokumboza ubuso (ukufaka iplati). Kusetshenziswa kabanzi ezindaweni ezinkulu zemikhumbi, ezimbonini zemishini esindayo, ezimbonini zezimoto njalo njalo. Ukwelashwa kwendawo ngokuhlikihla ngesibhamu, amandla okushaya, umphumela wokuhlanza usobala. Kodwa ukucutshungulwa kwe-shot piece workpiece processing shot, kulula ukwenza i-deformation workpiece, futhi i-steel shot hit surface workpiece (kungakhathaliseki ukuthi i-shot blasting noma i-shot peening, i-metal base material deformation, ngoba akukho pulasitiki, i-peel ephukile, kanye ne-oil film deformation nge-base material, ngakho-ke nge-oil workpiece, i-shot blasting, i-shot peening ayikwazi ukususa uwoyela ngokuphelele.
5, ukuqhumisa isihlabathi nakho kuyindlela yokuhlanza ngomshini, kodwa ukuqhumisa isihlabathi akuyona ukuqhumisa ngokudubula, ukuqhumisa isihlabathi kuyisihlabathi esifana nesihlabathi se-quartz, ukuqhumisa ngokudubula kuyi-pellet yensimbi. Ezindleleni zokwelapha ubuso bezinto zokusebenza ezikhona, umphumela wokuhlanza wokuhlanza ukuqhumisa isihlabathi. Ukuqhumisa isihlabathi kufanelekile ukuhlanza ubuso bezinto zokusebenza ngezidingo eziphakeme. Kodwa-ke, imishini yamanje yokuqhuma isihlabathi ejwayelekile yaseShayina yakhiwe kakhulu nge-hinge, i-scraper, i-bucket lifti kanye neminye imishini yokuthutha isihlabathi esindayo yasendulo. Abasebenzisi badinga ukwakha umgodi ojulile futhi benze ungqimba olungangeni manzi ukufaka imishini, izindleko zokwakha ziphezulu, izindleko zokulungisa nokulungisa zinkulu. Ngokunaka kwezwe lonke ukuvikelwa kwemvelo kanye nempilo yezimboni, ngoba inqubo yokuqhumisa isihlabathi inokukhiqiza uthuli olukhulu hhayi nje kuphela ukungcola okukhulu kwemvelo, kodwa futhi kulula ukuholela esifweni somsebenzi somqhubi (i-silicosis), inenani elikhulu lokuqhumisa ngokudubula ukuze kuthathelwe indawo ukuqhumisa isihlabathi.
Lokhu okungenhla kumayelana nomehluko phakathi komshini wokuqhumisa isihlabathi nomshini wokuhlikihla ama-shot peeping, ngokwesingeniso sawo, singaqonda ngokucacile ububanzi bokusetshenziswa kanye nezici zokusetshenziswa kwemishini, ukuze idlale ukusebenza kahle kwayo, ukuze ihlangabezane nezidingo zokusetshenziswa.
