Isiphetho:I-crusher ye-gyratory ineempawu ezinhle zokucisha ama-particle ngendlela efanayo, ukusebenza okuphezulu kokucisha, kanye nokuphindaphindeka okukhulu kokucisha njalo njalo. Isetshenziswa kabanzi emisebenzini yokwakha izinto zokwakha, emkhakheni we-metallurgy kanye nemikhakha ye-chemistry.
Isithuthukisi se-gyratory sinezinzuzo zokwenza ama-particle aqhubekayo, ukusebenza okuphezulu kokucisha, nokwanda okukhulu kwamazinga okucisha njalo njalo. Sisetshenziswa kakhulu ekukhiqizeni izinto zokwakha, ezolimo zezimboni zezinto zezimboni kanye nezimboni zezinto zekhemikhali. Ekuqeqeshweni okungokoqobo, izinga lama-particle e-ore lihluke, futhi ukungalingani kwempahla kuyabonakala kakhulu.
Isithuthukisi se-gyratory sihlale sineminyaka yokusebenza emifushane ngenxa yokuphazamiseka kwesisekelo sesikhulu se-eccentric, okuqeda ukwandisa isikhathi sokuhlinzwa kwezinto, kodwa futhi kwandisa izindleko zokulungisa futhi kwakha ukukhiqiza kwemveliso.
Nge-ngxenye elandelayo, sifuna ukugxila ezikhungweni nezindlela zokuvimbela ukwehluleka kwangaphambi kwexesha kwe-eccentric sleeve ye-gyratory crusher.
Isimo somsebenzi kanye nezinkinga ze-gyratory crusher
I-eccentric sleeve, i-moving cone kanye ne-conical sleeve yizinto ezijikelezayo zomphakathi ze-gyratory crusher. I-eccentric sleeve yingxenye ebaluleke kakhulu ye-gyratory crusher ukuze iphumelele umsebenzi wayo. Isikhumba sayo sangaphandle esiyindilinga sihlangene nomqondiso we-gyratory crusher, futhi isikhungo sendilinga yangaphakathi sinendawo ethile engenalo ukulingana noqeqeshwe kwesikhungo sesikhumba sangaphandle.
Ekusebenzeni kwesibhoshwe se-gyratory crusher, ukuze kuqinisekiswe ukusebenza okuhle phakathi kwesiliva esikhulukazi nesithombe se-base shaft kanye nendawo yokuxhumana yesithombe esikhulu sezithombe ezijikelezayo, futhi kunciphisa i-coefficient yokusabalala kwesithunzi, ilayeli le-Babbitt alloy ivame ukuboshwa endaweni yomthunzi oqondile yangaphandle kanye nendawo yangaphakathi yesiliva esikhulukazi. Ngemva kokuba i-gyratory crusher isebenze isikhathi esithile, isikhulukazi esikhulukazi singahluleka ngenxa yokwehla kwe-Babbitt metal endaweni.
Izinto ezithinta isikhathi sokusebenza sesikhwama esine-eccentric
Isimo sokuhlangana
Kukhona izinhlobo ezintathu zokuhlakazeka ezihlobene nesikhwama esine-eccentric, okungukuthi, ukuhlangana phakathi kwesikhumba esikhulu sesikhwama esine-eccentric nesikhwama sesikhwama esisisekelo, ukuhlangana phakathi kwesikhumba sangempela sesikhwama esine-eccentric nesisu esikhulu esiphezulu sesikhwama esisijikelezayo, nokuhlangana phakathi kwesisu esikhulu esiphezulu sesikhwama esisijikelezayo nesikhumba sangempela sesikhwama sethusi lesikhwama esine-conical. Isimo sokuhlangana sinamandla kakhulu ekukhiqizeni isikhathi sokusebenza sesikhwama esine-eccentric.
(1) Ukuhlangana okungaphezulu phakathi kwesikhumba esikhulu esikhonkconkconke sesiliba se-eccentric kanye nesiliba sesahluko sobusika
Kusetshenziswa ukungafani okuqondile phakathi kwesikhumba esikhulu esikhonkconkconke sesiliba se-eccentric kanye nesiliba sesahluko sobusika. Ngokuvamile, indawo yokuvumelana yesikhumba esikhulu esikhonkconkconke sesiliba se-eccentric yi-D4. Uma ukuhlangana kungqinile kakhulu, isiba se-eccentric kulula ukuthi siqiniswe ngesikhathi sokuqhuba umqhubi we-gyratory. Ngakolunye uhlangothi, uma ukuhlangana kungekho okuqinile, kulula ukukhiqiza umthwalo wokuthinta ngesikhathi sokuqhuba umqhubi we-gyratory.
(2) Ukuhlangana okuhle phakathi kwesikhumba sangaphakathi sensikazi ephuthumayo kanye nomkhondo oyinhloko ophakathi ophansi wesikhwama esikhulu esiqhubayo.
Ukuze umshini wokucisha ngokujikijela usebenze kahle, kukhethwe ukulingana okukhulu phakathi kwesandla sangaphakathi sendawo eguquguqukayo ne-shaft eyinhloko engaphansi yesikhunta esijikijelayo. Ngokuvamile, indawo yokwahlukahlukana kwesandla se-silinda sangaphakathi sendawo eguquguqukayo isebenzisa i-D4. Uma lokhu kulingana kuqinile kakhulu, umshini wokucisha ngokujikijela awusoze usebenze kahle. Ngakolunye uhlangothi, uma lokhu kulingana kungaphansi kakhulu, kulula ukuvelisa umthwalo womphumela ngesikhathi somsebenzi womshini wokucisha ngokujikijela.
(3) Ukuhlangana okuhle phakathi kwe-shaft eyinhloko ephezulu ye-cone eguquguqukayo ne-surface yangaphakathi ye-sleeve ye-copper ye-sleeve ye-conical
I-surface yangaphakathi ye-sleeve ye-conical (sleeve ye-copper) iyisiliinda, ehlanganiswa ne-shaft eyinhloko ku-cone eguquguqukayo. I-surface yangaphandle ye-sleeve ye-conical iyiconical, ehlanganiswa ne-sleeve yesihlangu sesibambo. Ekuhambeni kwe-gyratory crusher, uma i-shaft eyinhloko engaphansi ye-cone eguquguqukayo ihamba ngandlela ethile, i-shaft eyinhloko ephezulu ye-cone eguquguqukayo ithatha i-conical sleeve ihambe ngandlela ehlukene nokuhamba kwe-offset.
Ukuqondiswa okuhle kwesikhathi sokuhlanganiswa phakathi kwesisekelo kanye nensiza engezansi, nensiza engezansi kanye nensiza ephezulu
Isikhwama esingumqondo sikhishwa esisekelweni somshini, isiphetho esiphezulu sesithambo esibuthakathaka sikhishwa emzimbeni wesikhwama esiphezulu, futhi isisekelo somshini, umzimba wesikhwama esingezansi nomzimba wesikhwama esiphezulu zixhunyaniswe ndawonye ngezinto ezinamathiselwe. Uma isikhathi phakathi kwesisekelo somshini nomzimba wesikhwama esingezansi kanye nesikhathi phakathi komzimba wesikhwama esingezansi nomzimba wesikhwama esiphezulu kungafani, ukungafani kwesikhwama esingumqondo ekusebenzeni kuyoba ngokungafani, futhi isikhwama esingumqondo sizakhiqiza
Iphuthi lokugcoba
Ekwenzeni okuqondile, ngenxa yokwehluleka kwesikhwama, uthuli lungena emkhathini weoyili kusuka phansi kwesigqoko esibuthakathaka, okuholela ekukhuluphalisweni kweoyili yokugcoba. Izinto ezingalungile zifinyelela esigqokweni esingumkhathi ngeoyili, okuholela ekusebenzeni okubi kwesigqoko esingumkhathi.
Ukukhuluphala kwempahla ye-Babbitt ye-eccentric sleeve
Ukukhuluphala kwempahla ye-Babbitt ye-eccentric sleeve kunesithakazelo esithile ekuphileni kwesigqoko esingumkhathi. Ukuze kuvunyelwe ukuba impahla ye-Babbitt ingawuphuthumi ngokungavamile, "izinkuni ze-dovetail" ne"zingqimba" (njengoba kuboniswe esithombeni) zivame ukusetshenziswa.
Izimbangela zokuphila okufushane kwe-eccentric sleeve
Ukuphila okufushane kwe-eccentric sleeve kubangelwa ikakhulukazi:
(1) Ukuhlangana okungalungile kwe-eccentric sleeve, i-conical sleeve kanye nesiphetho seshaft esisezantsi nasesiphethweni seshaft esiphezulu se-moving cone, okuholela ekukhulu kwemiphumela yokuthinta nokunye ukubuyiselwa kwi-eccentric sleeve ngesikhathi sokusebenza kwe-gyratory crusher.
(2) Ukuhlukahluka kwesithuba sokwakhiwa phakathi kwesisekelo sesikhululo, umzimba wesiphetho esisezantsi, nomzimba wesiphetho esiphezulu, okubangela ukungafani kokuhlakazeka kwe-tapered sleeve, okuholela ekuhlukumezeni.
(3) Kunezinto eziningi ezingcolileyo ezitholakala emantini okunciphisa ukushakaza, okuholela ekuqhekezeni kwesikhumba esingaphandle.
(4) Ikhwalithi yokuthungwa kwe-Babbitt alloy esikhumbeni esingaphandle ayifani nezidingo.
Izinyathelo zokugwema
Ngokubheka izizathu ezingenhla zokuphela kwesikhathi esifushane sesikhumba esingaphandle se-gyratory crusher, kufanele kuthathwe izinyathelo zokugwema ezilandelayo:
(1) Ngesikhathi kokunakekelwa kwe-gyratory crusher, isikhumba esingaphandle kanye nesihlathi sethusi sesikhumba esingqamile kufanele siqondwe ngokuqondile ngokuvumelana nokulinganisa okushiwo idrawing ukuze kuqinisekiswe ukuthi kuhambisana.
(2) Uma ufake umzimba wesikhungo esiphezulu nomzimba wesikhungo esisezantsi, ngaphansi kwesimo lapho inkinobho yesikhonkwane ingafakwa khona, engeza ama-gasket phakathi komzimba wesikhungo esiphezulu nomzimba wesikhungo esisezantsi ukuze uqinisekise ukuthi isikhala phakathi kwamazimbasikhungo siyiqondisile.
(3) Ngesikhathi sokugcinwa, isikhonkwane sokuvala esesingeni phakathi senkuni elisuka nenkuni elisuka kanye nekhuba lothuli kufanele siqeqeshwe ukuze kuqinisekiswe ukuthi isikhonkwane sokuvala siqondisile. Futhi, shintsha amafutha okuqeqeshwa angcolile ngesikhathi.
(4) Qinisa ukulandelwa kwesinqumo sokulungisa isikhonkwane se-eccentric sleeve Babbitt alloy ukuze uqinisekise ukulungisa kwayo.
Ngenxa yokufakwa kwezimboni, imishini enkulu neyenza umsebenzi ngesivinini esikhulu seyisikhungo, futhi i-gyratory crusher enkulu yokugxila isetshenziswa kakhulu emisebenzini yezimboni. Ngakho-ke, kubalulekile kakhulu ukuqonda izizathu zokuhluleka kwesigaba esingumqhubi we-eccentric sleeve ye-gyratory crusher ngokushesha futhi kuthuthukiswe izindlela ezisebenziswayo. Umsebenzi kufanele alandele ngokucophelela isimo sesigaba esingumqhubi we-eccentric sleeve ye-gyratory crusher, aqongele izizathu zokuhluleka kwesigaba esingumqhubi, futhi athuthukise inqubo yokulungisa nokubekwa kwesigaba esingumqhubi.
