Ngesikhathi sokusebenza, ipuleti lomhlathi livame ukugqokwa, okuthinta ukusebenza okuvamile kwe-crusher yomhlathi.Leli phepha licwaninga ngensimbi yensimbi ene-carbon alloy crusher, futhi lidingida umthetho wokushintsha ubulukhuni bepuleti lomhlathi kanye nokumelana nokugqokwa, ukuze kunqunywe izinga lokushisa lokucisha lapho ukumelana nokugqoka kwepuleti lomhlathi kufinyelela ezingeni elihle.
Ukukhethwa kwempahla yomhlathi
1. Ekwenziweni, ipuleti lomhlathi eligudlukayo kanye nepuleti lomhlathi eliqinile lenziwe ngensimbi ephezulu ye-manganese engagugi, i-bearing liner kanye ne-eccentric bearing liner yenziwe nge-cast babbitt alloy, futhi ipuleti lomhlathi lenziwe ngensimbi yokusansimbi ukuze lithuthukiswe. ukuqina.I-jaw plate ye-jaw crusher idinga ukusebenza ngaphansi kwezimo ezingagugi, ukumelana nokushayisana kanye nezimo ezinokuqina okuphezulu.Abakhiqizi abahlukene basebenzisa izinto ezihlukile zamapuleti emihlathi, njengensimbi ephezulu ye-manganese, insimbi ye-manganese emaphakathi, insimbi exutshwe nengxubevange, insimbi engagugi ne-carbon low alloy nensimbi ephezulu ye-chromium.
2. Insimbi engamelana ne-carbon low-alloy engagugi itholakala ngokungeza izakhi zengxubevange ehlukahlukene njenge-Cr, Si, Mn, Mo, V ngesisekelo sensimbi ye-carbon-medium, futhi isamba sokuqukethwe kwe-alloy singaphansi kuka-5. %.Lolu hlobo lwensimbi ene-medium-carbon low-alloy wear-resistant lungalungisa kahle okuqukethwe kwekhabhoni ehlukene kanye nokuqukethwe kwe-alloy element, ngakho-ke lungafaniswa nezinqubo ezihlukene zokwelashwa kokushisa ukuze kutholwe izici ezihlukene zemishini, ngakho-ke ludonse ukunakwa okwengeziwe nokusebenzisa.Kuleli phepha, kwacutshungulwa ukumelana nokugqokwa kwe-medium carbon low alloy ZG42Mn2Si1REB, futhi kwaxoxwa ngomthetho wokushintsha ubulukhuni nokumelana nokugqoka ngezinga lokushisa lokucisha, futhi kwatholakala inqubo yokwelapha yokushisa engcono.
Tyena ukukhetha inqubo ukushisa ukushisa
Ngokwezici zensimbi ye-ZG42Mn2Si1REB, isakhiwo se-martensite esitholwe ngemva kokucisha sinobulukhuni obuphakeme nokumelana nokugqoka okungcono.Amaphuzu amathathu okushisa angu-870℃, 900℃ kanye no-930℃ akhethelwa ukwelashwa kokushisa, futhi izinga lokushisa elipholile lilungiswa ngokulinganayo ku-230℃.Ngenxa yokuthi okokusebenza akuqukethe i-elementi ye-Mo, ukuze kuqinisekiswe ukuqina, isixazululo se-Nacl esingu-5% sisetshenziselwa ukupholisa.
Imiphumela nokuhlaziya
1. Umthelela wokucisha izinga lokushisa ngobulukhuni nokumelana nokugqoka
Ukuqina kwamasampula acinywe kumazinga okushisa ahlukene kukalwa imitha yobulukhuni be-Rockwell ye-HR-150A, ekala amaphuzu angu-5 isikhathi ngasinye bese ithatha inani elimaphakathi.Kwatholakala ukuthi ngokwanda kwezinga lokushisa lokucisha, ubulukhuni bokucima kuqala bukhuphuke bese buncipha.Uma izinga lokushisa lokucisha lingu-870 ℃, ubulukhuni bungu-HRC53.Uma izinga lokushisa lokucisha likhuphuka lifike ku-900℃, ubulukhuni bukhuphukela ku-HRC55.Kungabonakala ukuthi ubulukhuni buyanda ngokunyuka kwezinga lokushisa;Uma izinga lokushisa liqhubeka nokukhuphuka lifinyelele ku-930℃, ubulukhuni buyehla bufike ku-HRC54, futhi kungatholakala ukuthi ubulukhuni buphezulu uma bucinywe ku-900℃.Ngakho-ke, ngokunyuka kwezinga lokushisa, ukulahlekelwa kwesisindo sokugqoka kunciphisa.Lapho izinga lokushisa liqhubeka nokukhuphuka lifinyelele ku-930 ℃, ukwehla kwesisindo somzimba kukhuphuka kube ngu-3.5mg.Kungabonakala ukuthi lapho icinywa ku-900 ℃, ubulukhuni bayo buphezulu futhi ukulahlekelwa kwesisindo sokugqoka akutholakali.I-medium carbon low alloy wear-resistant steel ZG42Mn2Si1REB inokumelana okuhle nokugqokwa, okubonisa futhi ukuthi inqubo ngalesi sikhathi iyinqubo efanele yokwelapha ukushisa.
2. Ukuqhathaniswa kokumelana nokugqoka phakathi kwe-carbon low alloy nensimbi ephezulu ye-manganese
Ukukhombisa ukumelana nokugqokwa okuphezulu kwensimbi ye-carbon alloy ephakathi ZG42Mn2Si1REB, le nto iqhathaniswa nensimbi ephezulu ye-manganese i-ZGMn13.Phakathi kwazo, i-ZG42Mn2Si1REB ihlolwe ngokuya ngezimo zobuchwepheshe ezibalulwe ngenhla zokucisha ku-900℃ kanye nokushisa ku-230℃, kanye nensimbi ephezulu ye-manganese i-ZGMn13 iphathwe ngokuqinisa amanzi.Imiphumela yokuhlola ibonisa ukuthi ukumelana nokugqoka kwangaphambili kuyizikhathi ezingu-1.5 zamuva, okubonisa ukuthi ipuleti yomhlathi yensimbi ye-carbon low alloy steel isebenzise ngokugcwele amandla ezinto ezibonakalayo futhi inokumelana okuhle kakhulu kokugqoka ngaphansi kwezimo ezifanele zokwelashwa kokushisa.
Ngokuqondene nezindleko zezinto ezibonakalayo, insimbi ephezulu ye-manganese iqukethe kufika ku-13% Mn, ngakho-ke idinga ukudla izakhi eziningi ze-alloy.Uma kuqhathaniswa nensimbi ephezulu ye-manganese, insimbi ye-carbon low alloy steel ZG42Mn2Si1REB iqukethe kuphela i-alloy elements engu-3%~4%, futhi ayiqukethe ama-elementi e-Cr ne-Mo anenani eliphezulu, ngakho-ke inenzuzo yokuncintisana ngentengo ephezulu.Ngaphezu kwalokho, uma kucatshangelwa inqubo yokushisa ukushisa, insimbi ye-carbon low alloy iron icinywa ku-900 ℃ futhi ifudumale ku-230 ℃, kuyilapho ukwelashwa kwamanzi okuqinile kwensimbi ephezulu ye-manganese kuvame ukudlula i-1000 ℃, ngakho-ke izinga lokushisa lokucisha langaphambili liphansi, isikhathi sokushisa sifushane, futhi umphumela wokonga amandla uphawuleka kakhulu.Inqubo engcono yokwelapha ukushisa yasetshenziswa epuleti lomhlathi le-crusher, okusobala ukuthi kwathuthukisa ukumelana nokugqokwa, futhi umjikelezo wokushintsha ipuleti lomhlathi wanwetshwa kusukela ku-150d kuya ku-225d, ngezinzuzo ezisobala zezomnotho.
Ngocwaningo mayelana nokumelana nokugqokwa kwepuleti lomhlathi lensimbi ephakathi kwe-carbon low alloy crusher yomhlathi, imiphumela ibonisa ukuthi lapho icinywa ku-900 ℃, i-microstructure ngemva kokucisha i-martensite, ngalesi sikhathi, ubulukhuni buphakeme, isisindo sokugqoka ukulahlekelwa kuphansi, futhi ukumelana nokugqoka kungcono.
I-Shanvim njengomphakeli womhlaba wonke wezingxenye ezigqokwayo ze-crusher, sakha izingxenye zokugqoka ze-cone crusher zezinhlobo ezahlukene zama-crusher.Sineminyaka engaphezu kwengu-20 yomlando emkhakheni we-CRUSHER WEAR PARTS.Kusukela ngo-2010, sithumele eMelika, eYurophu, e-Afrika nakwamanye amazwe emhlabeni.
