Ingxenye engaphezulu ye-jaw plate enyakazayo ye-jaw crusher ixhunywe ne-eccentric shaft, ingxenye engezansi isekelwa i-thrust plate, futhi ipuleti lomhlathi eligxilile ligxiliswe kuhlaka.Lapho i-eccentric shaft izungeza, ipuleti lomhlathi eligudlukayo lithwala ngokuyinhloko isenzo sokukhishwa kwento, kuyilapho ipuleti lomhlathi eligxilile lithwala ngokuyinhloko isenzo sokusika esislayidikayo.Njengengxenye enezinga eliphezulu lokuguga kwe-jaw crusher, ukukhetha kwezinto zepuleti lomhlathi kuhlobene nezindleko nenzuzo yomsebenzisi.
Insimbi ephezulu ye-manganese
Insimbi ye-manganese ephezulu iyinto evamile yepuleti lomhlathi we-crusher yomhlathi, enekhono elihle lokumelana nemithwalo enomthelela.Kodwa-ke, ngenxa yesakhiwo se-crusher, i-engeli yokuvula phakathi kwemihlathi enyakazayo negxilile inkulu kakhulu, okulula ukubangela ukuthi i-abrasive islayide.Izinga lokuqina alanele, ngakho-ke ubulukhuni bobuso bepuleti lomhlathi buphansi, futhi okokusebenza okulimazayo kusikeka ebangeni elifushane, futhi ipuleti lomhlathi liguga ngokushesha.
Ukuze kuthuthukiswe impilo yesevisi yepuleti lomhlathi, kuye kwathuthukiswa izinto ezihlukahlukene zepuleti lomhlathi, njengokwengeza i-Cr, i-Mo, i-W, i-Ti, i-V, i-Nb nezinye izakhi ukuze kulungiswe insimbi ephezulu ye-manganese, nokwenza ukusabalalisa. ukuqinisa ukwelashwa ngensimbi ephezulu ye-manganese.Thuthukisa ubulukhuni bayo bokuqala namandla esivuno.Ukwengeza, insimbi ye-manganese ephakathi, insimbi ye-alloy ephansi, insimbi ye-chromium cast kanye nezinhlanganisela zensimbi ephezulu-manganese nazo zithuthukisiwe, zonke zisetshenziswe kahle ekukhiqizeni.
Insimbi ye-manganese emaphakathi
Insimbi ye-manganese emaphakathi yasungulwa yi-Climax Molybdenum Co., Ltd. futhi yafakwa ngokusemthethweni kulungelo lobunikazi lase-US ngo-1963. Indlela yokuqina ithi: uma inani le-manganese lehliswa, ukuzinza kwe-austenite kuncipha, futhi uma ithinteka noma igugile, i-austenite ijwayele ukuguquka futhi ibangele ukuguqulwa kwe-martensitic, ngaleyo ndlela ithuthukise ukumelana kwayo nokugqoka.Ukwakheka okuvamile (%) kwensimbi ye-manganese emaphakathi: 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr nezinye izici zokulandelela V, Ti, Nb, umhlaba ongavamile, njll. Impilo yangempela yesevisi yensimbi ye-manganese emaphakathi ipuleti lomhlathi linganyuswa ngaphezu kuka-20% uma liqhathaniswa nensimbi ephezulu ye-manganese, futhi izindleko zilingana nensimbi ephezulu ye-manganese.
I-chromium cast iron ephezulu
Nakuba insimbi ephezulu ye-chromium inokumelana nokugqokwa okuphezulu, kodwa ngenxa yokuqina kwayo okungekuhle, ukusebenzisa i-chromium cast iron ephezulu njengepuleti lomhlathi kungase kungazuzi imiphumela emihle.Eminyakeni yamuva nje, i-chromium cast iron ephezulu isetshenziselwe ukugxilisa noma ukuhlanganisa imihlathi yensimbi ephezulu ye-manganese ukuze kwakhiwe imihlathi eyinhlanganisela.Ukumelana nokugqoka okuhlobene kuphakeme izikhathi ezingu-3, futhi impilo yesevisi yemihlathi iye yathuthukiswa kakhulu.Lokhu futhi kuyindlela ephumelelayo yokwandisa impilo yesevisi yepuleti yomhlathi, kodwa inqubo yayo yokukhiqiza iyinkimbinkimbi, ngakho-ke kunzima kakhulu ukuyikhiqiza.
Insimbi ephonswe nge-carbon low alloy cast steel
Insimbi ye-Medium-carbon low-alloy cast steel ibuye isetshenziswe kabanzi ukumelana nokugqokwa.Ngenxa yokuqina kwayo okuphezulu (≥45HRC) nokuqina okufanele (≥15J/cm²), ingakwazi ukumelana nokusikwa kwezinto kanye nokukhishwa okuphindaphindiwe.Ukukhathala okungapheli, ngaleyo ndlela kubonisa ukumelana okuhle kokuguga.Ngesikhathi esifanayo, i-medium-carbon low-alloy cast steel nayo ingalungisa ukwakheka kanye nenqubo yokwelashwa kokushisa ukuze kuguqulwe ubulukhuni nokuqina ebangeni elibanzi ukuze kuhlangatshezwane nezidingo zezimo zokusebenza ezahlukene.Ukuhlolwa kokukhiqiza nokusebenza kubonisa ukuthi impilo yesevisi yepuleti lomhlathi wensimbi ye-carbon low-alloy evamile ingaba yinde izikhathi ezingaphezu kwezingu-3 kunensimbi ye-manganese ephezulu.
Iziphakamiso zokukhetha okubalulekile kwepuleti lomhlathi
Ukufingqa, ngokufanelekile, ukukhethwa kwezinto zepuleti lomhlathi kufanele kuhlangabezane nezidingo zokuqina okuphezulu nokuqina okuphezulu, kodwa ukuqina nobulukhuni bento ngokuvamile kuphikisana.Ngakho-ke, ekukhethweni kwangempela kwezinto zokwakha, kuyadingeka ukuqonda izimo zokusebenza futhi ukhethe ngokufanele.impahla.
Umthwalo womthelela ungenye yezinto ezibalulekile okufanele zicatshangelwe ekukhetheni izinto ezifanele.
Uma ukucaciswa kukhudlwana, izingxenye ezigqokiwe zisinda kakhulu, izinto ezichotshoziwe ziba nezigaxa, futhi kuba mkhulu umthwalo owuthwalayo.Ngalesi sikhathi, insimbi eguquliwe noma ehlakazekayo iqinise insimbi ephezulu ye-manganese isengasetshenziswa njengento yokukhetha izinto.
Kuma-crushers aphakathi nendawo namancane, umthwalo womthelela ezingxenyeni ezigqokekayo awumkhulu kakhulu, futhi kunzima ukusebenza kanzima ngensimbi ephezulu ye-manganese.Ngaphansi kwezimo ezinjalo zokusebenza, izinzuzo ezinhle zobuchwepheshe nezomnotho zingatholwa ngokukhetha insimbi ene-carbon low-alloy steel noma i-high-chromium cast iron/low-alloy steel composite material.
Ukwakheka nobulukhuni bezinto ezisetshenziswayo nakho kuyizici ezingenakuzitshwa ekukhetheni izinto ezifanele.
Ngokuvamile, ukuphakama kokuqina kwempahla, kuyanda ukubaluleka kokuqina kwempahla yezingxenye ezigqokekayo.Ngakho-ke, ngaphansi kwesimo sokuhlangabezana nezidingo zokuqina, izinto ezinobunzima obukhulu kufanele zikhethwe ngangokunokwenzeka.
Ukukhethwa kwezinto ezibonakalayo okunengqondo kufanele futhi kucabangele indlela yokugqoka yokugqoka izingxenye.
Uma ukusika ukugqoka kuyizinto eziyinhloko, ubulukhuni kufanele bucatshangelwe kuqala lapho kukhethwa izinto;uma ukugqoka kwepulasitiki noma ukugqoka kokukhathala kuyizinto eziyinhloko, ipulasitiki kanye nokuqina kufanele kucatshangelwe kuqala lapho kukhethwa izinto zokwakha.
Yiqiniso, lapho ukhetha izinto zokwakha, ukufaneleka kwenqubo kufanele kucatshangelwe, ukuze kube lula ukuhlela ukukhiqizwa nokulawulwa kwekhwalithi.
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.
