Summary: Ku-Gyratory crusher, uqobo olungenhla ludlala indima ebalulekile ekuqineni isikhali esiyinhloko, ukudlulisa amandla, nokumunca imithwalo enjalo. Le ndatshanaigxile ekwakhiweni komqamelo ophezulu, imisebenzi emikhulu, ukugcinwa kwansuku zonke, kanye nenqubo yonke yokushintsha evamile kubasebenzi abaphakathi komsebenzi....
Njengomshini omkhulu wokugobhoza ophambili wokugaya okukhulu nezinga elikhulu lokumba, izitshalo zokuhlanganisa, nezitshalo zokuphatha izimayini, i i-crusher ye-gyratory kusetshenziswa kakhulu kwezobuchwepheshe, izinto zokwakha, amakhemikhali, kanye nomkhakha wecementi.
The main frame—comprising the upper, middle, and bottom frames—forms the core component of the i-crusher ye-gyratory. Among these, the upper frame plays a critical role in stabilizing the main shaft, transferring power, and absorbing heavy impact loads. Long-term heavy impact, vibration and dust erosion inevitably cause frame deformation, sealing failure and metal fatigue, making upper frame replacement one of the most essential overhaul works for i-crusher ye-gyratorys.
This article focuses on the upper frame’s structure, core functions, daily maintenance, and the complete standardized replacement procedure for field operators.
Uhlaka Lomumo KoMbutho Ongaphezulu
Indaweni yokuphakama komongo wokuhlanganisa kwe- i-crusher ye-gyratory okuvamile kuqukethe izingxenye ezine eziyinhloko: i-frame ephezulu, i-bushing yenkwa enkulu, ibhentshi lokungenisa umthwalo, kanye nomshini wokumunca.
Uhlaka olungaphezulu sebenza njengesisekelo semfundiso; sinomklamo onesibindi esiphezulu ngezakhiwo zikashidi oshaywe noma odidiyelwe, sakhelwe ukumelana namandla amakhulu okuphazamiseka adalwa inqubo yokuphahlaza.
Ibhodi yemikhono enkulu benza njengokuthi "umgexo obumbene", esebenzisa ungqimba lokusebenza ukunciphisa ukungqubana phakathi komjikelezo omkhulu nomzimba ongezansi.
Ithambo lokudonsela ukulinganisa amandla ase-axial kosekeli oyinhloko, kuvimbela ukwehluleka kwezingxenye nokonakala kwemishini okubangelwa yomthwalo ongalingani.
Umshini wokufaka uphawu benza njenge "mvulamlomo womphunga," uvimela uthuli ukungena ezingxenyeni zangaphakathi futhi ngaleyo ndlela ubanzi ukwazi kwazo ukuphila isikhathi eside.
Imisebenzi Eyinhloko Yesakaza Esiphezulu
Eku i-crusher ye-gyratory, uhlaka ophezulu uvamise ukusebenza nemisebenzi emihlanu:
Ukusekela Kokuphakamisa 2.1
Phezulu kwento ephezulu yes Frame iqinisekisa ibhodi. I-bushing ngaphakathi kwindawo phakathi kwebhodi iqhina eliyinhloko le-crushing cone, ivumela ukunyakaza kwe-gyratory kwe-mantle.
2.2 Lungisa indawo yesitoreji esiyinhloko
Ngokusebenzisa ukufanisa okufakiwe phakathi kwe-bushing ye-shaft enkulu kanye ne-fram etholakalayo phezulu, kuvimbela ukuphuma kwe-radial ye-shaft enkulu ngesikhathi sokujija okukhulu kanye nokuzungezisa okulayishiwe kakhulu.
2.3 Thumela Amandla Okucindezela
Amandla okulimala amavela ezinto ezingavuthwa egumbini lokuwaca ahanjiswa ngokuya kumgodi owenza ukuphikisa (i-mantle) nge-shaft enkulu aye phezulu kwifreyimu futhi ahlukaniswe kwifreyimu engenhla aye ebhentshini le-crusher.
2.4 Ukuthwala Umthwalo
Njengengxenye enkulu yesakhiwo, uhlaka olungaphezulu luyehlisa amandla axhunywe e-radial nasemandleni ayingxenye ye-axial akhiqizwa ngesikhathi sokugoqa, kugcina ukuvumelana okobuso be-i-crusher ye-gyratory.
2.5 Isithiyo Nokuthatha Izikhukhula Zonke
Ithuluzi lokuhambisa umthwalo nokuvimbela liyasebenza ndawonye ukwamukela ingxenye enkulu yamandla okushubha, kuvimbela umhlinzeki wobuso obukhazimulayo ukuthi ungazingeni ukumelana nokukhathala kwesakhiwo ngenxa yokushubha okuphakathi kwesikhathi eside.
3. Ngakaphi ukushintsha Uhlaka Ophezulu
Ngaphambi kokusebenzisa nokushintsha indlela ephezulu, abasebenzi kufanele bahlole ukuthi ukushintshwa kubalulekile yini ngokwesimo sokusebenza kwemishini.
Izimbangela eziqondile zokushintshwa:
- Ukuqina okungapheli kokushayisana kakhulu: Ukwakha kokushukuma kuqhubeka nokudlula u-0.1mm ngemva kokulungisa.
- Ukuphazamiseka kwesakhiwo: Umonakalo wezakhiwo emgqeni ongephezulu, njengokuphukubheka, ukugqokeza noma ukukhathala kwensimbi okubonakalayo.
- Ukwehluleka okuphezulu kokuvala: uthuli alususi nhlobo ngisho nangemva kokushintsha izingxenye zokuvimbela kabili.
- Ukubambelela okuphansi ekuqondeni ukusebenza: Ukuwohloka okubukhali emihlanganweni yokuxhuma okuvimba ukunemba kokusebenza futhi akukwazi ukubuyiselwa ngokulungisa.
- Ukuqhuma okungazinzile kophawu oluyinhloko: Ukugqokwa okungajwayelekile kwe-bushing kuholela ekudidekelweni kwenqenqa enkulu.
4. Inqubo Ejwayelekile Yokushintsha Uhlaka Olungaphezulu
4.1 Ukulungiselela ngaphambi kokukhishwa kwemishini
Yeka ukondla ngokuphelele, susa zonke izinto ezikwi-cavity yokugoqwa, bese uvala imishini. Cisha ugesi nohlelo lwekhwalithi, futhi uvale imishini ukuqinisekisa ukuphepha kokwakha.
4.2 Ukusula Izithako Ezisizayo
Susa izivikeli zomquba zangaphandle, ama-assemblies okugcwalisa, amasondo axhumisa nezitsha zokugcoba. Khipa ibhodi lokuphakamisa kanye nebhodi lesikhwama esikhulu ukuze uziveze uhlaka oluphakeme.
4.3 Phakamisa futhi ususe Uhlaka Olukhulu Lwesangempela Oluphezulu
Sebenzisa amathuluzi okuphakamisa abuchwepheshile ukuze uvimbe uhlaka oluphezulu ngokuqinile. Susa zonke izikulufu zokuxhuma phakathi kohlakahle oluphezulu noshumi oluphakathi, bese uvusa uhlaka oludala nxazonke ukugwema ukudlidliza futhi nokubangela ukungqubana.
4.4 Faka Isisekelo Esiphezulu Esisha
Beka uhlaka olusha oluphezulu oluqinile endaweni enembile. Qinisa zonke izingodo ngokulinganayo njengoba uzihamba ujike ujike ukuqinisekisa ukusabalala kwezinkomba ngokuyikho.
4.5 Ukuhlanganyela Kabusha Izingxenye Zangaphakathi
Faka kabusha i-bushing yomkhawulo omkhulu, ibhodi lokuphakela kanye nesixazululo sokufaka. Faka amafutha anele ukuze kwakheke ungqimba lokuxubha olungaphazanyiswa.
4.6 Ukuhlolwa Kwephutha Ngemva Kokushintshwa
Yenza ukuhlolwa kokungasebenzi komthwalo okungahambi isikhathi esivame ukuba phakathi kwamahora ayi-1 kuya kwabayi-2. Bheka idatha yomoya ophukayo, izinga lokushisa nomsindo wokusebenza. Uma amandla okuphukuma komoya engaphansi kuka-0.1mm futhi kwabakhona umsindo ongajwayelekile, ukuphakelwa okusemthethweni kokukhiqiza kungaqhubeka.
5. Ukugcinwa Kwansuku zonke Ukwehlisa Impilo Yokusebenza Kwephansi Phezulu
Ukuze ugweme ukushintshwa njalo njalo futhi unciphise izindleko zokugcinwa, abasebenzi kumele balandele umkhuba wokugcinwa kwansuku zonke olandelayo:
5.1 Ukuntywila okungaguquki
Gcwalisa i-bushing yesiqu asokha ethangini enkulu ngenkanyiso njalo emahoreni ayi-8 ukuze uvimbele ukukhuma okungamakhulu nxa futhi ungeze ukwanda kwezinga lokushisa.
5.2 Ukuhlolwa Kwasembo Sevisi Nsukazi Ngesonto
Hlola izinto zokufaka zokuvimbela i-rubber njalo ngesonto ukuze uthole ukonakala noma ukukhula kwamadala. Ukushintsha kusenesikhathi kuvimbela ukungena komhlabathi nokugqokwa ngaphakathi.
5.3 Ukuqapha Ukugumbusa Okusebenzayo Ngasikhathi Sangempela
Sebenzisa amasensela okudlidliza ukuze qapha uhlaka oluphezulu ngesikhathi sangempela. Uma ukuhlaba okudlidliza kudlula u-0.1mm, vala umshini wokugibela ngokushesha ukuze kuhlolwe.
5.4 Ukuvimbela Ukweqisa Okungaphansi Kokuphakelwa Kwezimpahla
Overfeeding will significantly increase upper frame pressure and accelerate metal fatigue. Feeding capacity must not exceed the i-crusher ye-gyratory’s rated processing volume.
6. Izinzuzo Zesigubhu Esiphezulu se-SBM HGT I-Gyratory Crusher
SBM's Umshini wokugqobhoza we-HGT okungaqhubeki Inezici zesakhiwo esinamandla aphezulu, esisinda kakhulu esingaphezulu, esihlinzeka ngamandla akhulu ngokuphelele kwesakhiwo sonke. Uhlelo lokugoqa oluthuthukisiwe lubonakalisa ukuqinisa kanye nokumelana nokucindezeleka, olwenzela ukuthi ukuguquka nokushintshwa kube kuncane ngokuphumelelayo.
Yakhiwe ngokubekezelela izimo zokukhiqiza eziyinqaba kakhulu, iqinisekisa impilo yesevisi ende, ukusebenza okuphephile futhi okuthembekile, kanye nezindleko eziphansi zokukhiqiza nokugcinwa konke.
