Ukuqhumisa Isanti – Kuchanekile kwaye kuyaguquguquka

Ukuqhumisa isanti kusebenzisa umoya ocinezelweyo njengamandla aphambili okutshiza izinto ezingaqhelekanga ezirhabaxa ngesantya esiphezulu kumphezulu wezinto zokusebenza. Indawo yayo ephambili kukucoca + ukurhabaxa ngokuchanekileyo, kunye nemisebenzi eyongezelelweyo yokususa ubumdaka. Yinkqubo ebalulekileyo yonyango lwangaphambi kokutshiza kunye nokufaka i-electroplating emva koko.

Amandla anokulungiswa ngokulula: uxinzelelo lomoya lokuqhuma kwesanti ngokuxinzelela yi-0.5–0.7 MPa, kwaye ukuqhuma kwesanti ngokufunxa yi-0.3–0.5 MPa. Ukuqhuma okuncediswa ngamanzi ngokuxinzelela okuphezulu (ukuqhuma okumanzi) kungasetyenziswa kwezinye iimeko. Izixhobo zombane ziquka izinto ezirhabaxa ezingaqhelekanga ezifana nesanti ye-quartz, i-alumina emdaka exutywe ne-fused, kunye namaqokobhe e-walnut alungele ukusingqongileyo. Ubungakanani bezinto ezincinci bukhethwa ngokusekelwe kwiimfuno zoburhabaxa bomphezulu; i-grit ye-G120–G80 iyacetyiswa kudidi lokususa umhlwa lwe-Sa2.5.

Injongo yayo ephambili kukususa ngokupheleleyo ioyile, iipeyinti ezindala, kunye nomhlwa kumphezulu wezinto zokusebenza, ukulawula ngokuchanekileyo uburhabaxa bomphezulu, kunye nokuphucula ukunamathela kweepeyinti ezilandelayo. Ingasetyenziselwa ukukrola ngobugcisa kunye nonyango lwe-matte lweemveliso ze-elektroniki.

Ifanelekile kwiimpahla zokusebenza ezincinci, ezahlukeneyo, nezintsonkothileyo, ezifana neenkuni, iindawo ze-aluminium ezinodonga oluncinci, kunye nokususwa komhlwa kwindawo ethile kwiindawo zeenqanawa. Inobuhlobo ngakumbi kwiintsimbi ezithambileyo kunye namaphepha abhityileyo ukuze kuthintelwe ukuguguleka, kwaye ihambelana nomgangatho we-GB/T 8923.1 wokususwa komhlwa.

Ukuzikhupha ngeenaliti – Kuchanekile kwaye Kugxile

Ngokufana nokuqhumisa isanti ngendlela yamandla, ukucofa i-shot peening kusebenzisa umoya ocinezelweyo okanye amandla amancinci e-centrifugal ukutshiza i-round shots ngesantya esiphezulu kumphezulu we-workpiece. Igxile kakhulu ekuqiniseni umphezulu kwaye ifanelekile kunyango lwengingqi lweendawo ezinzima.

Amandla ahlengahlengiswa ngokulula, nto leyo evumela ulawulo oluchanekileyo lwe-engile yokutshiza kunye nesantya seeshothi, nto leyo eyenza ukuba ifaneleke kwiimbombo zangaphakathi ezintsonkothileyo kunye neekona ezingenako ukugqunywa kukuqhumisa ngeshothi. Imidiya, ehambelana nezo zisetyenziswa ekuqhumiseni ngeshothi, ziishothi ezingqukuva ezinobubanzi obuyi-0.1–2.0 mm. Zinemiphezulu egudileyo, azikrweli kakhulu umsebenzi, kwaye zinokuphinda zisetyenziswe.

Umsebenzi wayo ophambili kukwandisa ubulukhuni bomphezulu, amandla okudinwa, kunye nokumelana nokuguguleka ngokusebenza nzima, ngelixa ikwabonelela ngokulungiswa koxinzelelo kunye nokususa ukutsha. Isiphumo sayo sokucoca sibuthathaka kunesanti.

Iimeko ezisebenzayo ziquka ukuqina kwendawo kwezinto ezibalulekileyo ezithwala umthwalo ezifana nezixhobo zemoto, iindawo zeenqwelo moya, kunye neebheringi. Qaphela ukuba izinto zokusebenza ezineoyile yomphezulu kufuneka zisuswe amafutha kwangaphambili ukuze kuthintelwe ukungcoliswa kweemipu kwaye kuchaphazele iziphumo.

Ukuqhumisa iiShot - Ibhetshi kwaye iyasebenza

Ukuqhumisa ngemipu kusebenzisa amandla e-centrifugal oomatshini njengamandla angundoqo. I-impeller ejikelezayo ngesantya esiphezulu (ivili lokuqhuma) iphosa imipu ejikelezayo ngesantya esiphezulu kumphezulu wezinto zokusebenza. Igxila ekucoceni ibhetshi esebenza kakuhle kakhulu + ukuqinisa umphezulu, inomgangatho ophezulu wokwenza izinto ngokuzenzekelayo, kwaye lukhetho olukhethwayo kwimveliso enkulu.

Ngokuphathelele amandla, isantya se-impeller sinokufikelela kwi-1500–3000 r/min, kwaye isantya sokuqala sokudubula sifikelela kwi-100 m/s. Ayixhomekekanga kwi-air compressor kwaye inika umlinganiselo ophezulu wokusebenza kwamandla kunezinye iinkqubo ezimbini ezisetyenziswa ixesha elide, kunye nokusebenza okuphezulu ngaphezu kwama-30% kunokuqhuma kwesanti ngesandla. Ii-media zii-shots ezingqukuva, ezingenamphetho, eziqhele ukuphoswa ngentsimbi okanye ii-shots zentsimbi engagqwaliyo, ezinobubanzi obuyi-0.8–2.5 mm. Zingaphinda zisetyenziswe izihlandlo ezingamakhulu, kwaye kufuneka ukuphinda kuzaliswe rhoqo kuphela (ukuphinda kuzaliswe ≤ 10% yomthamo uwonke).

Umsebenzi wayo oyintloko kukususa i-oxide scale, ukubumba isanti, kunye nomhlwa kwi-castings kunye ne-forgings, ngelixa inyusa ubulukhuni bomphezulu kunye nokumelana nokudinwa ngokusebenza nzima kunye nokunciphisa uxinzelelo lwangaphakathi.

Iimeko ezisebenzayo ikakhulu zizinto ezininzi zokusebenza eziqhelekileyo, ezifana neepleyiti zentsimbi, iitoweri ze-wind turbine, kunye neenxalenye ze-chassis zeemoto. Ingadityaniswa nemigca yokuhambisa ezenzekelayo ukuze kwenziwe imveliso eqhubekayo, ithobela imigangatho yezixhobo ze-JB/T 8355 kunye nomgangatho wokususa umhlwa we-GB/T 8923.1.
