Kwicandelo lokuhlolwa koomatshini okuchanekileyo, ukuchaneka nokuthembeka kwezixhobo zokuhlola izikrufu zelothe kuchaphazela ngokuthe ngqo ulawulo lomgangatho wezixhobo zokuhambisa umatshini. Ukukhethwa kwezinto ezisisiseko zesixhobo sokubona izikrufu selothe ngundoqo ekumiseleni ubomi benkonzo kunye nokusebenza kwezixhobo. Icandelo elikhethekileyo legranite lezixhobo zokuhlola izikrufu zelothe, kunye neenzuzo zalo ezibalaseleyo zesayensi yezinto, lifikelele kwinqanaba lokwandisa ubomi benkonzo ngeminyaka eli-12 xa kuthelekiswa nezinto zesinyithi, nto leyo ezisa utshintsho olukhulu kushishino lokuhlola ukuchaneka.
Imida yezinto ezifakwe kwisinyithi
Isinyithi esitshisiweyo besisoloko sisetyenziswa kakhulu ekwenzeni izixhobo zovavanyo lwezikrufu ze-lead ngenxa yexabiso laso eliphantsi kunye nokuqina okuthile. Nangona kunjalo, isinyithi esitshisiweyo sineengxaki ezininzi kwizicelo ezisebenzayo. Okokuqala, isinyithi esitshisiweyo asinazinzo kubushushu. Ngexesha lokusebenza kwesixhobo sokubona izikrufu ze-lead, ubushushu obuveliswa sisixhobo ngokwaso kunye notshintsho kubushushu bendalo bunokubangela ukuguquka kobushushu bezixhobo zesinyithi esitshisiweyo, okuchaphazela ukuchaneka kokufunyanwa kwezikrufu ze-lead. Njengoko ixesha lokusetyenziswa lisanda, isiphumo esiqokelelweyo sokuguquka kobushushu siya kubangela ukuba impazamo yokulinganisa iqhubeke yanda. Okwesibini, ukumelana nokuguguleka kwesinyithi esitshisiweyo kunqongophele. Ngexesha lokuhamba okuphindaphindiweyo kwesikrufu se-lead kunye nomsebenzi wokuhlola, umphezulu wecandelo lesinyithi esitshisiweyo uthambekele ekugugulekeni ngenxa yokungqubana, okubangela ukwanda kokuvuleka kokulingana kwaye ngaloo ndlela kunciphisa ukuchaneka nokuthembeka kwezixhobo zokuhlola. Ukongeza, isinyithi esitshisiweyo sinokumelana nokugqwala okubuthathaka. Kwiindawo ezimanzi okanye ezinegesi erhabaxa, izixhobo zesinyithi esitshisiweyo zithambekele ekugqwaleni nasekugqwaleni, nto leyo efinyeza kakhulu ubomi benkonzo yesixhobo.
Iingenelo zesayensi yezinto ezibonakalayo zezinto zegranite
I-Granite, njengesixhobo esifanelekileyo sezixhobo zokuhlola izikrufu ze-lead, ineenzuzo zemvelo. Ulwakhiwo lwayo lwangaphakathi luxinene kwaye lufana, lunomlinganiselo ophantsi kakhulu wokwanda kobushushu, oluhlala luqala kwi-5 ukuya kwi-7×10⁻⁶/℃, kwaye phantse aluchaphazeleki kutshintsho lobushushu. Oku kwenza ukuba isixhobo sokubona izikrufu ze-lead sigcine ubungakanani obuzinzileyo kunye neemilo zezixhobo ze-granite nokuba zisebenza ixesha elide okanye zitshintsha kakhulu kubushushu bendalo, nto leyo enika isalathiso esithembekileyo sokuchongwa kwezikrufu ze-lead kunye nokuqinisekisa ukuchaneka kwedatha yokulinganisa.
Ngokuphathelele ukumelana nokuguguleka, ubunzima be-Mohs ye-granite bunokufikelela kwi-6-7, obuphezulu kunobo be-cast iron. Ngexesha lokuhamba rhoqo kwe-lead screw, umphezulu we-granite component awugugi lula kwaye unokuhlala unendawo echanekileyo yokungena, ukuqinisekisa ukuzinza kwexesha elide kokufunyanwa kwe-lead screw. Ngokwezibalo zedatha yesicelo esisebenzayo, izinga lokuhla kokuchaneka kwe-lead screw detector esebenzisa i-granite components lihamba kancinci ngaphezu kwe-80% kunelo le-cast iron components phantsi kweemeko ezifanayo zokusebenza.
Ngokuphathelele ukumelana nokugqwala, i-granite lilitye lendalo elineempawu zeekhemikhali ezizinzileyo kwaye alisebenzi kwizinto eziqhelekileyo ze-asidi okanye ze-alkaline. Kwanakwiindawo ezintsonkothileyo zoshishino, izinto ze-granite aziyi konakala kukugqwala, nto leyo eyandisa ubomi benkonzo yesixhobo sokubona izikrufu se-lead.
Iziphumo ezimangalisayo zokusetyenziswa kunye nexabiso leshishini
Isiphumo esisebenzayo sezixhobo ezikhethekileyo zegranite kwizixhobo zokuxilonga i-lead screw simangalisa kakhulu. Ngophando olulandelayo lwamashishini amaninzi okuvelisa oomatshini, kufunyenwe ukuba ubomi obuqhelekileyo benkonzo yezixhobo zokuxilonga i-lead screw ezisebenzisa izixhobo zesinyithi esityhidiweyo bumalunga neminyaka esi-8, ngelixa emva kokusebenzisa izixhobo zegranite, ubomi benkonzo yezixhobo zokuxilonga i-lead screw bunokwandiswa ukuya kwiminyaka engama-20, ukwanda kweminyaka eli-12 epheleleyo. Oku akunciphisi kakhulu iindleko zamashishini zokutshintsha izixhobo zokuvavanya, kodwa kukwanciphisa ixesha lokungasebenzi elibangelwa kukungasebenzi kakuhle kwezixhobo kwaye kuphucula ukusebenza kakuhle kwemveliso.
Ngokwembono yophuhliso lweshishini, ukusetyenziswa kwezinto zegranite kukhuthaze ukuqhubela phambili kwetekhnoloji yokubona ngokuchanekileyo. Ubomi bayo benkonzo obude kakhulu kunye nokusebenza kwayo okuzinzileyo kubonelela ngesiqinisekiso esithembekileyo sokuhlolwa kwezikrufu zelead ngokuchanekileyo, kunceda ishishini lokuvelisa oomatshini ukuba livelise iimveliso ezikumgangatho ophezulu kwaye liphucule ukukhuphisana kwalo lonke ishishini.
Izixhobo ezikhethekileyo zegranite zezixhobo zokuhlola izikrufu ze-lead ziye zoyisa ngempumelelo iziphene zezixhobo zesinyithi esityhidiweyo ngenxa yeenzuzo zesayensi yezinto eziphathekayo, zifikelele kwinqanaba eliphezulu lobomi benkonzo. Kwixesha elizayo, ngokunyuka okuqhubekayo kwemfuno yokuhlolwa ngokuchanekileyo, izixhobo zegranite ziya kudlala indima ebalulekileyo kwiindawo ezininzi kwaye zinike inkxaso eqinileyo kuphuhliso lweshishini lokuvelisa ngokuchanekileyo.
