I-crusher yomhlathi, ipuleti lomhlathi elihlala ligqokwa njalo?

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 lokuphuka kwemihlathi nokuguga, ukukhethwa kwezinto zomhlathi kuhlobene nezindleko nenzuzo yabasebenzisi.

I-manganese ephezuluInsimbi Insimbi ye-manganese ephezulu iyinto evamile yepuleti lomhlathi we-jaw crusher, inomthelela omuhle ukumelana nomthwalo, kodwa ngenxa yesizathu sesakhiwo se-crusher, i-Angle ephakathi kwepuleti lomhlathi eliguquguqukayo neligxilile likhulu kakhulu, kulula ukubangela ukushelela kwe-abrasive. ukuze deformation ukuqina akwanele ukwenza ipuleti emhlathini ebusweni ubulukhuni iphansi, abrasive short-range cutting, umhlathi plate bafake ngokushesha. Ukuze kuthuthukiswe impilo yesevisi yepuleti lomhlathi, kuye kwathuthukiswa izinto ezihlukahlukene zepuleti lomhlathi, njengokwengeza i-Cr, Mo, W, Ti, V, Nb nezinye izakhi ukuze kulungiswe insimbi ephezulu ye-manganese, nokuqinisa ukuhlakazeka. ukwelashwa kwensimbi ephezulu ye-manganese ukuthuthukisa ubulukhuni bayo bokuqala kanye namandla okukhiqiza. Ngaphezu kwalokho, inhlanganisela yensimbi ye-manganese ephakathi, insimbi ye-alloy ephansi, insimbi ephezulu ye-chromium cast kanye nensimbi ephezulu ye-manganese iye yathuthukiswa, futhi imiphumela emihle ifinyelelwe ekukhiqizeni.

I-China Manganese Steel yasungulwa okokuqala yiNkampani ye-Climax Molybdenum futhi yafakwa ohlwini ngokusemthethweni kulungelo lobunikazi lase-United States ngo-1963. Indlela yokuqina imi kanje: ngemva kokwehliswa kokuqukethwe kwe-manganese, ukuzinza kwe-austenite kuncipha, futhi uma ingaphansi kokuthinteka noma ukuguga, I-austenite ijwayele ukuguqulwa kwe-martensitic eyenziwe yi-deformation, okuthuthukisa ukumelana kwayo nokugqoka. Ukwakheka okuvamile kwensimbi ye-manganese (%) : 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr nezinye izakhi zokulandelela V, Ti, Nb, umhlaba ongavamile njalonjalo. Impilo yangempela yesevisi ye-medium manganese iron jaw plate ingaphezulu kuka-20% ephakeme kunaleyo yensimbi ephezulu ye-manganese, futhi izindleko ziqhathaniswa nalezo zensimbi ephezulu ye-manganese.

03 Insimbi ephezulu ye-chromium cast Nakuba insimbi ephezulu ye-chromium inokumelana nokuguga okuphezulu, kodwa ngenxa yokuqina kwayo okungenamandla, ukusetshenziswa kwe-chromium cast iron ephezulu njengepuleti lomhlathi akuzuzi imiphumela emihle. Eminyakeni yamuva nje, insimbi ephezulu ye-chromium ephonswe ngensimbi noma ehlanganiswe nepuleti yomhlathi yensimbi ephezulu ye-manganese ukuze yakhe ipuleti lomhlathi eliphindwe kabili, ukumelana nokugqoka okuhlobene okufika izikhathi ezi-3, ukuze impilo yesevisi yepuleti lomhlathi inyuke kakhulu. Lokhu futhi kuyindlela ephumelelayo yokuthuthukisa impilo yesevisi yepuleti yomhlathi, kodwa inqubo yayo yokukhiqiza iyinkimbinkimbi, ngakho-ke kunzima ukuyikhiqiza.

Insimbi eyi-Carbon low alloy cast steel iphinde isetshenziswe kabanzi engagugi, ngenxa yokuqina kwayo okuphezulu (≥45HRC) nokuqina okufanele (≥15J/cm²), ingamelana nokusikwa kokubalulekile kanye nokukhishwa okuphindaphindiwe okubangelwa ukuchitheka kokukhathala, ngaleyo ndlela ibonise okuhle. ukumelana nokugqoka. Ngesikhathi esifanayo, i-medium carbon low alloy cast steel nayo ingashintshwa ngokubunjwa kanye nenqubo yokwelashwa kokushisa, ukuze ukuqina nokuqina kungashintsha ebangeni elikhulu ukuze kuhlangabezane nezidingo zezimo ezahlukene zokusebenza. Ukuhlolwa kokusebenza kukhombisa ukuthi impilo yesevisi ye-medium carbon low alloy steel jaw plate inde izikhathi ezingaphezu kwezingu-3 kunei-manganese ephezuluinsimbi.
Izingxenye Ezimelana Nokugqoka

Iziphakamiso zokukhetha ipuleti lemihlathi:
Kafushane, ukukhethwa kwe-jaw plate material kahle ukuze kuhlangatshezwane nezidingo zobulukhuni obuphezulu kanye nokuqina okuphezulu, kodwa ukuqina nokuqina kwempahla kuvame ukuphikisana, ngakho ekukhethweni kwangempela kwezinto zokwakha, kufanele siqonde ngokugcwele izimo zokusebenza, ezinengqondo. ukukhethwa kwezinto.
I-1) Umthwalo womthelela ungenye yezinto ezibalulekile okufanele zicatshangelwe ekukhetheni izinto ezinengqondo. Ukucaciswa okukhulu, ukusinda kwezingxenye ezivame ukuguga, i-lumpiness eyengeziwe yezinto eziphukile, kanye nomthwalo omkhulu womthelela. Ngalesi sikhathi, insimbi ephezulu yemanganese eguquliwe noma eqiniswe ukuhlakazwa isengasetshenziswa njengento ekhethwayo. Kuma-crushers aphakathi nendawo amancane, umthwalo womthelela othwala izingxenye zokugaya kalula awukhulu kakhulu, ukusetshenziswa kwensimbi ephezulu ye-manganese, kunzima ukuyenza isebenze ngokugcwele ukuqina. Ngaphansi kwezimo ezinjalo zokusebenza, ukukhethwa kwensimbi ye-carbon low alloy steel noma i-chromium cast iron ephezulu/i-low alloy steel composite material kungathola izinzuzo ezinhle zobuchwepheshe nezomnotho.
I-2) Ukwakheka kwezinto kanye nobulukhuni bayo nakho kuyizici ezingenakunakwa ekukhethweni kwezinto ezibonakalayo. Ngokuvamile, ukuphakama kokuqina kwempahla, ukuphakama kwezidingo zokuqina kwempahla yengxenye egqokeka kalula, ngakho-ke ngaphansi kwesimo sokuhlangabezana nezidingo zokuqina, impahla enobunzima obuphezulu kufanele ikhethwe ngangokunokwenzeka. .
I-3) Ukukhethwa kwezinto ezinengqondo kufanele futhi kucabangele indlela yokugqoka yezingxenye eziguga kalula. Uma ukugqoka kokusika kuyisici esiyinhloko, ubulukhuni kufanele bucatshangelwe kuqala lapho kukhethwa izinto zokwakha. Uma ukugqoka kwepulasitiki noma ukukhathala kuwukugqoka okuyinhloko, ipulasitiki kanye nokuqina kufanele kucatshangelwe kuqala lapho kukhethwa izinto zokwakha. Yiqiniso, ekukhethweni kwezinto zokwakha, kufanele futhi icabangele ukufaneleka kwenqubo yayo, ukuhlela kalula ukukhiqizwa nokulawulwa kwekhwalithi.
