Emkhakheni wokukhiqiza nokuhlola ngokunemba, ukusebenza kokuguquguquka kokushisa kwezinto kuyisici esibalulekile esinquma ukunemba nokuthembeka kwemishini. I-Granite ne-cast iron, njengezinto ezimbili ezisetshenziswa kakhulu ezimbonini, zidonsele ukunaka okukhulu ngomehluko wazo wokusebenza ezindaweni ezishisa kakhulu. Ukuze siveze ngokubonakalayo izici zokuguquguquka kokushisa kwazo zombili, sisebenzise umthwebuli wezithombe ochwepheshe wokushisa ukwenza izivivinyo zokusebenza eziqhubekayo zamahora angu-8 kumapulatifomu e-granite ne-cast iron anencazelo efanayo, eveza umehluko wangempela ngedatha nezithombe.
Umklamo wokuhlola: Lingisa izimo zokusebenza ezinzima futhi ubambe umehluko ngokunembile
Kulolu vivinyo, kukhethwe amapulatifomu e-granite nensimbi ephothiwe enobukhulu obungu-1000mm×600mm×100mm. Endaweni yokusebenzela yezimboni elingisiwe (izinga lokushisa elingu-25±1℃, umswakama ongu-50%±5%), ngokusabalalisa ngokulinganayo imithombo yokushisa ebusweni bepulatifomu (ukulingisa ukukhiqizwa kokushisa ngesikhathi sokusebenza kwemishini), ipulatifomu yasebenza ngokuqhubekayo ngamandla angu-100W amahora angu-8. I-FLIR T1040 thermal imager (enesinqumo sokushisa esingu-0.02℃) kanye nenzwa yokufuduka kwe-laser enembile kakhulu (enokunemba okungu-±0.1μm) kwasetshenziswa ukuqapha ukusatshalaliswa kokushisa kanye nokuguqulwa kobuso bepulatifomu ngesikhathi sangempela, futhi idatha yaqoshwa kanye njalo ngemizuzu engama-30.
Imiphumela elinganisiwe: Bona ngeso lengqondo umehluko wokushisa bese ulinganisa igebe lokuguquguquka
Idatha evela ku-thermal imager ikhombisa ukuthi ngemva kokuba ipulatifomu yensimbi ephonswe ngensimbi isebenze ihora elilodwa, izinga lokushisa eliphezulu kakhulu lifinyelele ku-42℃, okuyi-17℃ ephakeme kunezinga lokushisa lokuqala. Ngemva kwamahora ayisishiyagalombili, izinga lokushisa lenyuke laya ku-58℃, kwavela ukusatshalaliswa kwe-gradient yokushisa okuhlukile, okunomehluko wokushisa ongu-8℃ phakathi komphetho nendawo ephakathi. Inqubo yokushisa yepulatifomu ye-granite ithambile kakhulu. Izinga lokushisa lenyuka laya ku-28℃ kuphela ngemva kwehora eli-1 futhi lizinza ku-32℃ ngemva kwamahora ayi-8. Umehluko wokushisa kobuso ulawulwa ngaphakathi kuka-2℃.
Ngokusho kwedatha yokuguquguquka, zingakapheli amahora angu-8, ukuguqulwa okuqondile endaweni ephakathi yesikhulumi sensimbi ephonswe kufinyelele ku-0.18mm, kanti ukuguqulwa okugobile emaphethelweni kwakungu-0.07mm. Ngokuphambene nalokho, ukuguqulwa okuphezulu kwesikhulumi segranite kungu-0.02mm kuphela, okungaphansi kwe-1/9 yaleyo yensimbi ephonswe. Ijika lesikhathi sangempela lenzwa yokufuduka kwe-laser liphinde liqinisekise lo mphumela: Ijika lokuguquguquka kwesikhulumi sensimbi ephonswe liyashintshashintsha kakhulu, kuyilapho ijika lesikhulumi segranite licishe lizinze, libonisa ukuzinza okunamandla kakhulu kokushisa.
Ukuhlaziywa Okuyisisekelo: Izakhiwo zezinto ezibonakalayo zinquma umehluko ekuguqukeni kokushisa
Imbangela ebalulekile yokuguquguquka okukhulu kokushisa kwensimbi ephonswe ku-coefficient yayo ephezulu yokwanda kokushisa (cishe 10-12 ×10⁻⁶/℃), kanye nokusatshalaliswa okungalingani kwe-graphite ngaphakathi, okuholela ekushiseni okungahambisani nokushisa kanye nokwakheka kokuhlushwa kokucindezeleka kokushisa kwendawo. Okwamanje, insimbi ephonswe inomthamo wokushisa ophansi kakhulu, futhi izinga lokushisa layo likhuphuka ngokushesha lapho limunca inani elifanayo lokushisa. Ngokuphambene nalokho, i-coefficient yokwanda kokushisa kwe-granite ingu-(4-8) ×10⁻⁶/℃ kuphela. Isakhiwo sayo sekristalu siminyene futhi siyafana, sinokusebenza kahle kokushisa okuphansi nokusatshalaliswa ngokulinganayo. Uma sihambisana nekhono layo eliphezulu lokushisa, sisengagcina ukuzinza kobukhulu ezindaweni zokushisa eziphakeme.
Ukukhanyiselwa kokusetshenziswa: Ukukhetha kunquma ukunemba, ukuzinza kudala inani
Emishinini efana namathuluzi omshini oqondile kanye nemishini yokulinganisa enama-three-coordinate, ukuguqulwa kokushisa kwezisekelo zensimbi ephonswe kungaholela emaphutheni okucubungula noma okuhlola, okuthinta isivuno semikhiqizo efanelekile. Isisekelo se-granite, esinokuqina kwayo okuvelele kokushisa, singaqinisekisa ukuthi imishini igcina ukunemba okuphezulu ngesikhathi sokusebenza kwesikhathi eside. Ngemva kokuba inkampani ethile yokukhiqiza izingxenye zezimoto ithathe indawo yesikhulumi sensimbi ephonswe ngesikhulumi se-granite, izinga lamaphutha elilinganiselwe lezingxenye eziqondile lehle lisuka ku-3.2% laya ku-0.8%, futhi ukusebenza kahle kokukhiqiza kwanda ngo-15%.
Ngokusebenzisa isethulo esinembile kanye nokulinganisa okunembile kwesithombe sokushisa, umehluko ekuguqukeni kokushisa phakathi kwe-granite nensimbi ephonswe ubonakala ngokushesha. Embonini yanamuhla ephishekela ukunemba okuphelele, ukukhetha izinto ze-granite eziqinile ekushiseni ngokungangabazeki kuyisinyathelo esihlakaniphile sokuthuthukisa ukusebenza kwemishini nokuqinisekisa ikhwalithi yomkhiqizo.
