Kwintsimi yokuhlolwa komatshini ochanekileyo, ukuchaneka kunye nokuthembeka kwezixhobo zokuhlola i-screw lead zichaphazela ngokuthe ngqo ukulawulwa komgangatho wamacandelo okuhanjiswa koomatshini. Ukukhethwa kwezinto eziphathekayo zamacandelo angundoqo we-screw detector ekhokelayo ngundoqo ekunqumeni ubomi benkonzo kunye nokusebenza kwezixhobo. Icandelo elikhethekileyo legranite lezixhobo zokuhlola izikrufu zelothe, kunye neenzuzo zalo ezibalaseleyo zenzululwazi, lizuze impumelelo ekwandiseni ubomi benkonzo ngeminyaka eli-12 xa kuthelekiswa nemathiriyeli yentsimbi, izisa inguqu eguqukayo kushishino lokuhlola oluchanekileyo.
Unyino lwamacandelo entsimbi
Intsimbi yentsimbi kudala iyinto esetyenziswa ngokuqhelekileyo ukwenza amacandelo ezixhobo zokuvavanya izikrufu ngenxa yexabiso eliphantsi kunye nokuqina okuthile. Nangona kunjalo, i-iron cast ineziphene ezininzi kwizicelo eziphathekayo. Okokuqala, i-iron ayinazinzo olubi lwe-thermal. Ngethuba lokusebenza kwe-screw detector ekhokelayo, ubushushu obuveliswa sisixhobo ngokwawo kunye nokutshintsha kweqondo lokushisa lokusingqongileyo kunokubangela ukuguqulwa kwe-thermal ye-cast iron components, echaphazela ukuchaneka kokufunyanwa kwe-screw lead. Njengoko ixesha lokusetyenziswa lisanda, isiphumo esongezelekayo soguquko lwe-thermal luya kubangela ukuba impazamo yokulinganisa iqhubeke yanda. Okwesibini, ukunyanzeliswa kwentsimbi yentsimbi kunqunyelwe. Ngethuba lokuhamba ngokuphindaphindiweyo kwe-screw ekhokelayo kunye nokusebenza kokuhlolwa, indawo yecandelo lentsimbi etyhidiweyo ixhomekeke ekugqokeni ngenxa ye-friction, okubangelwa ukwanda kwe-fit clearance kwaye ngaloo ndlela kuncitshiswe ukuchaneka kunye nokuthembeka kwezixhobo zokuhlola. Ukongeza, intsimbi etyhidiweyo inamandla okumelana nomhlwa. Kwiindawo ezifumileyo okanye ezinoburharha ezinerhasi, amacandelo entsimbi athanda ukugqwala kunye nokugqwala, anciphisa kakhulu ubomi benkonzo yezixhobo.
Izinto eziluncedo kwisayensi yezinto zegranite
Igranite, njengesixhobo esifanelekileyo kumalungu azinikeleyo ezixhobo zokuhlola izikrufu zelothe, ineengenelo zendalo zomzimba. Ubume bayo bangaphakathi bunobunzima kwaye bufana, kunye ne-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, ngokuqhelekileyo ukusuka kwi-5 ukuya kwi-7 × 10⁻⁶ / ℃, kwaye iphantse ingathinteki ngokutshintsha kweqondo lokushisa. Oku kwenza ukuba i-screw detector ekhokelayo igcine imilinganiselo ezinzileyo kunye neemilo zamacandelo egranite naphantsi kokusebenza kwexesha elide okanye ukuguquguquka okubalulekileyo kwiqondo lokushisa lokusingqongileyo, ukubonelela ngereferensi ethembekileyo yokubhaqa isikrufu sokukhokela kunye nokuqinisekisa ukuchaneka kwedatha yokulinganisa.
Ngokubhekiselele ekuchaseni ukugqoka, ubunzima be-Mohs be-granite bunokufikelela kwi-6-7, ephakamileyo kuneyentsimbi. Ngethuba lokuhamba rhoqo kwe-screw ekhokelayo, umphezulu wecandelo le-granite awugqoki lula kwaye unokuhlala ugcina i-high-precision fit clearance, iqinisekisa ukuzinza kwexesha elide lokufunyanwa kwe-screw lead. Ngokweenkcukacha-manani zedatha yesicelo esisebenzayo, ukuchaneka kwereyithi yokuhla kwesixhobo sokujonga isikrufu esikhokelayo kusetyenziswa izakhi zegranite zicotha ngaphezulu kwama-80% kunezo zixhobo zentsimbi phantsi kweemeko ezifanayo zokusebenza.
Ngokubhekiselele kwi-corrosion resistance, i-granite ilitye lendalo elineekhemikhali ezizinzile kwaye ayisebenzi ngezinto eziqhelekileyo ze-acidic okanye i-alkaline. Nakwiimeko zoshishino ezintsonkothileyo, amacandelo e-granite awayi konakaliswa yi-corrosion, eyongeza ngakumbi ubomi benkonzo ye-lead screw detector.
Iziphumo eziphawulekayo zesicelo kunye nexabiso leshishini
Isiphumo esisebenzayo sokusetyenziswa kwamacandelo e-granite akhethekileyo kwii-detectors ze-lead screw iphawuleka kakhulu. Ngophando olulandelelweyo lwamashishini amaninzi okwenziwa ngoomatshini, kwafunyaniswa ukuba umndilili wobomi benkonzo yezikhonkwane zelothe ezisebenzisa intsimbi etyhidiweyo imalunga neminyaka esi-8, ngelixa emva kokwamkelwa kwamacandelo egranite, ubomi benkonzo yezixhobo zokujonga izikrufu zelothe bunokwandiswa ukuya kutsho kwiminyaka engama-20, ukwanda kweminyaka eli-12 epheleleyo. Oku akunciphisi kakhulu iindleko zamashishini ukuba athathe indawo yezixhobo zovavanyo, kodwa kwakhona kunciphisa ixesha lokuphumla okubangelwa kukungasebenzi kakuhle kwezixhobo kunye nokwandisa ukusebenza kakuhle kwemveliso.
Ukusuka kwimbono yophuhliso lweshishini, ukusetyenziswa kwamacandelo e-granite kukhuthaze ukuqhubela phambili kobuchwephesha bokubona ngokuchanekileyo. Ubomi bayo benkonzo ende kakhulu kunye nokusebenza okuzinzile kunika isiqinisekiso esithembekileyo sokuhlolwa kwe-screw ehamba phambili echanekileyo, ukunceda imboni yokuvelisa oomatshini ivelise iimveliso ezikumgangatho ophezulu kunye nokuphucula ukukhuphisana kweshishini lonke.
Izixhobo ezikhethekileyo zegranite zezixhobo zokuhlola izikrufu ezikhokelayo ziye zanqoba ngempumelelo iziphene zamacandelo esinyithi ngenxa yeenzuzo zesayensi yezinto eziphathekayo, ukuphumeza ukwanda okubonakalayo kwinkonzo yobomi. Kwixesha elizayo, ngokunyuka okuqhubekayo kwimfuno yokuhlolwa ngokuchanekileyo, amacandelo e-granite abophelelekile ukuba adlale indima ebalulekileyo kwimimandla emininzi kwaye anike inkxaso eqinileyo kuphuhliso loshishino lokuvelisa oluchanekileyo.
