Yiziphi izinzuzo zesikhungo semishini yemashi yamaminerali yokuphonsa imishini?
Ama-mineral castings (ukhonkolo we-granite we-stanite axa resin) amukelwe kabanzi embonini yamathuluzi omshini isikhathi esingaphezu kweminyaka engama-30 njengezinto ezihlelekile.
Ngokusho kwezibalo, eYurophu, elinye lawo wonke amathuluzi emishini ayi-10 lisebenzisa amathuluzi amaminerali njengombhede. Kodwa-ke, ukusetshenziswa kwesipiliyoni esingafanele, imininingwane engaphelele noma engalungile ingaholela ekusolisweni nasebandlululweni ngokumelene nokukhululwa kwamaminerali. Ngakho-ke, lapho wenza imishini emisha, kuyadingeka ukuhlaziya izinzuzo nokubi kwama-mineral castings futhi uyiqhathanise nezinye izinto.
Isisekelo semishini yokwakha ngokuvamile sihlukaniswe nge-Iron Iron, i-Mineral Casting (Polymer kanye / noma i-Resin Resin ukhonkolo), isakhiwo sensimbi / se-welding (i-grouting / i-granite) netshe lemvelo (njenge-granite). Indwangu ngayinye inezimpawu zayo, futhi akukho zinto eziphelele zesakhiwo. Kuphela ngokuhlola izinzuzo nokubi kwezinto zokwenziwa ngokuya ngezidingo ezithile zesakhiwo, kungakhethwa yini izinto ezinhle kakhulu zezinhlelo.
Imisebenzi emibili ebalulekile yezinto zokwehlela - qinisekisa ukufakwa kwejometri, isikhundla kanye nokutholwa kwamandla kwezakhi, ngokulandelana izidingo zokusebenza (ukunemba, ukuqina, izidingo zomhlahlandlela), izidingo zodonga (intengo, inani, ukutholakala, izici zohlelo).
I. Izidingo Zokusebenza Zokusebenza Kwezinkampani
1. Izici ze-Static
Isikhombi sokukala izakhiwo ze-tuli zivame ukuqina kokuqina okungokwezinto ezibonakalayo ngaphansi komthwalo, kunokuba namandla aphezulu. Ukuze uthole ukonakala kwe-static elastic, ama-mineral castings angacatshangwa njenge-isotropic homegeneous sonto elalela umthetho kaHooke.
I-density kanye ne-modulus ye-elastic ye-mineral castings ngokulandelana ayi-1/3 yaleyo ye-cast iron. Kusukela amaminerali athutha kanye ne-cast irons inokuqina okufanayo, ngaphansi kwesisindo esifanayo, ubulukhuni bezinkulungwane zensimbi kanye nokusakazeka kwamaminerali kuyafana ngaphandle kokucabanga ngethonya lesimo. Ezimweni eziningi, ukuhlukaniswa kodonga lokuklama kwe-mineral castings kuvame ukuba izikhathi ezi-3 zokukhokhiswa kwensimbi, futhi lo mklamo ngeke ubangele izinkinga ngokuya ngezakhiwo zemishini zomkhiqizo noma zokuphonsa. Izinkomba zamaminerali zilungele ukusebenza ezindaweni ezi-static eziphethe ingcindezi (isib. Imibhede, izisekelo, amakholomu) futhi azifanele amakhamu ancishisiwe kanye / noma amatafula, amatafula, ama-palles, ama-prothers, ama-spindles asekelwa). Isisindo sezingxenye ezakhiwe ngezakhiwo sivame ukukhawulelwa imishini yabakhiqizi be-mineral casting, kanye nemikhiqizo yokuphonsa amaminerali ngaphezulu kwamathani ayi-15 ngokuvamile ayivelakancane.
2. Izici ezinamandla
Ijubane elikhulu elijikelezayo kanye / noma ukusheshisa shaft, kubaluleke kakhulu ukusebenza komshini. Ukuma okusheshayo, ukushintshwa kwamathuluzi okusheshayo, nokuphakelwa okuphezulu okuphezulu ngokuqhubekayo kuqinisa ukubuyiselwa kwemishini nokuthokoza okunamandla kwezingxenye zokwakheka komshini. Ngaphezu kokwakhiwa okuyisici kwengxenye, ukwehla, ukusatshalaliswa kweMisa, kanye nokuqina okunamandla kwengxenye kuthinteka kakhulu yizindawo eziphoqelelayo zezinto ezibonakalayo.
Ukusetshenziswa kwemali yamaminerali kunikeza isixazululo esihle kulezi zinkinga. Ngoba idonsa ama-vibrations amahlandla ayi-10 kangcono kunensimbi yendabuko yendabuko, inganciphisa kakhulu i-amplitude nemvamisa yemvelo.
Ekusebenzeni kwemishini okufana nemishini efana nemishini, kungaletha ukunemba okuphezulu, ikhwalithi ephezulu yendawo, kanye nempilo yamathuluzi ende. Ngasikhathi sinye, ngokuya ngomthelela womsindo, ama-mineral castings futhi enze kahle ngokuqhathanisa nokuqinisekiswa kwezisekelo, ukuhambisa izinhlaka kanye nezesekeli zezinto ezahlukahlukene zezinjini ezinkulu namasenti. Ngokusho kokuhlaziywa komsindo wethonya, ukukhonkotha kwamaminerali kungafinyelela ukuncishiswa kwasendaweni okungu-20% ezingeni lokucindezela komsindo.
3. Izakhiwo ezishisayo
Ochwepheshe balinganisela ukuthi cishe ama-80% okuphambuka kwamathuluzi womshini kubangelwa yimiphumela eshisayo. Inqubo yokuphazamiseka njengemithombo yokushisa yangaphakathi noma yangaphandle, ukusabalalisa, ukuguqula izindawo zokusebenza, njll zonke izimbangela zokuguqulwa kwe-thermal. Ukuze ukwazi ukukhetha izinto ezinhle kakhulu, kuyadingeka ukucacisa izidingo ezibonakalayo. Ukushisa okuningana nokushisa okuphansi okushisayo kuvumela ama-arealings amaminerali ukuba abe ne-inertia enhle ye-inertia yokushisa amathonya okushisa (njengokushintsha kwemisebenzi yokushintshana) kanye nokushintsha kokushisa okukhona. Uma kudingeka inzalo esheshayo njengombhede wensimbi noma izinga lokushisa lombhede livinjelwe, ukufudumeza noma amadivaysi okupholisa kungaphonswa ngokuqondile ekuphoqekeni kwamaminerali ukulawula izinga lokushisa. Usebenzisa lolu hlobo lwedivaysi yokunxeshezelwa kokushisa kunganciphisa ukwehla okubangelwa yithonya lokushisa kwezinga lokushisa, okusiza ukuthuthukisa ukunemba ngezindleko ezinengqondo.
II. Izidingo ezisebenzayo nezakhiwo
Ubuqotho yisici esihlukanisayo esihlukanisa ama-mineral castlings avela kwezinye izinto. Ukushisa okuphezulu kokuphonsa kwezikhundla amaminerali kungu-45 ° C, futhi kanye nokubumba okunembile okuphezulu kanye nokutholwa kwamathuluzi, izingxenye kanye nokukhishwa kwamaminerali kungaphonswa ndawonye.
Amasu athuthukisiwe wokuphonsa kabusha angasetshenziswa futhi ezincelweni zokuphonsa amaminerali, okuholele ezindaweni eziphakeme zokukhwela kanye nesitimela ezingadingi mabhuku. Njengezinye izinto zokwakha, izinkambo zamaminerali zingaphansi kwemithetho ethile yokwakheka kwesakhiwo. Ukuqina kodonga, izesekeli ezithwala umthwalo, ukufakwa kwamanje, ukulayisha nokulayisha izindlela konke kwehlukile kwezinye izinto ngezinga elithile, futhi kudingeka kubhekwe ngaphambi kwesikhathi ngesikhathi sokuqamba.
III. Izidingo Zezimali
Ngenkathi kubalulekile ukubheka kusuka eqophelweni lobuchwepheshe, ukusebenza kwezindleko kuya ngokuya kukhombisa ukubaluleka kwayo. Kusetshenziswa ama-mineral castings kuvumela onjiniyela ukuthi balondoloze ukukhiqizwa okubalulekile nezindleko zokusebenza. Ngaphezu kokonga izindlekoma machishini, ukusakaza, umhlangano wokugcina, kanye nokwanda kwezindleko zokwanela (ukugcinwa kwempahla nokuhamba) konke kuncishisiwe ngokufanele. Uma kucatshangelwa umsebenzi osezingeni eliphakeme lokudonswa kwamaminerali, kufanele kubhekwe njengephrojekthi yonke. Eqinisweni, kunengqondo ukwenza ukuqhathanisa kwentengo lapho isisekelo sifakiwe noma sifakwe ngaphambili. Izindleko eziphakeme kakhulu zokuqala yizindleko zezikhunta zokuphonswa kwamaminerali kanye namathuluzi, kepha lezi zindleko zingahlanjululwa ekusetshenzisweni kwesikhathi eside (izicucu ezi-500-1000 / isikhunta sonyaka (kanye nokusetshenziswa konyaka kucishe kube yizicucu eziyi-10-16.
IV. Ububanzi bokusebenzisa
Njengezinto ezihlelekile, ama-mineral castings ahlala esikhundleni sokubuyiselwa izinto zendabuko ngokwesakhiwo, futhi ukhiye wokuthuthuka kwawo okusheshayo ulele ekukhokhisweni kwamaminerali, isikhunta, nezinhlaka ezizinzile zokubopha. Njengamanje, ama-mineral castings asetshenziswe kabanzi emasimini amaningi emishini emishini efana nemishini yokugaya kanye nemishini esezingeni eliphakeme. Abakhiqizi bemishini yokugaya kube amaphayona emkhakheni wamathuluzi womshini besebenzisa ama-mineral castings yemibhede yomshini. Isibonelo, izinkampani ezidume umhlaba wonke ezinjenge-Aba Z & B, Bahmler, Jung, Mikrosa, Sched, tude, njll.
Ngokwanda njalo okunamandla, izinkambo zamaminerali nazo ziyathandwa yizinkampani ezihola phambili emhlabeni emkhakheni wama-grinders wamathuluzi. Umbhede wokuphonsa amaminerali unobulukhuni obuhle kakhulu futhi ungasusa kahle amandla okubangelwa ukusheshisa kwemoto eqondile. Ngasikhathi sinye, inhlanganisela ye-organic yokusebenza okuhle kwe-villaaration yokungenisa kanye nemoto yemoto eqondile ingathuthukisa kakhulu ikhwalithi ephezulu yokwenziwa kwempilo kanye nempilo yenkonzo yesondo lokugaya.
