Amapuleti angaphezulu kwegwadle, athathwe ezingqimbeni ezijulile zamadwala ekhwalithi ephezulu, adume ngokuzinza kwawo okukhethekile, okubangelwa izigidi zeminyaka zokuguga kwemvelo. Ngokungafani nezinto ezijwayele ukuwohloka kusukela ekuguquguqukeni kwezinga lokushisa, igwadle lihlala lizinzile ngaphansi kwezimo ezihlukahlukene. Lawa mapuleti enziwe ngegwadle elikhethwe ngokucophelela elinesakhiwo sekristalu esihle, enikeza ubulukhuni obumangazayo namandla okucindezela aphezulu angama-2290-3750 kg/cm². Futhi banesilinganiso sokuqina kwe-Mohs esingu-6-7, okubenza bamelane nokugqokwa, ama-asidi, nama-alkali. Ngaphezu kwalokho, i-granite imelana kakhulu nokugqwala futhi ayigqwali, ngokungafani nezinto zensimbi.
Njengento engeyona eyensimbi, igwagwagwa alinawo amandla kazibuthe futhi alingeni ekuwohlokeni kwepulasitiki. Iqine kakhulu kune-cast iron, inobulukhuni obuphindwe izikhathi ezingu-2-3 (uma iqhathaniswa ne-HRC>51). Lobu bunzima obuhle kakhulu buqinisekisa ukunemba okuhlala isikhathi eside. Ngisho noma ingaphezulu legwadle lingaphansi komthelela omkhulu, lingabangela kuphela ukuqhekeka okuncane, ngokungafani namathuluzi ensimbi, angase alahlekelwe ukunemba ngenxa yokuguqulwa. Ngakho-ke, amapuleti angaphezulu kwe-granite anikeza ukunemba okuphezulu nokuzinza uma kuqhathaniswa nalawo enziwe ngensimbi ensimbi noma insimbi.
I-Granite Surface Plates kanye Nezitendi Zazo Zokusekela
Amapuleti angaphezulu kwe-Granite ngokuvamile abhangqwa nezitendi ezenziwe ngokwezifiso ukuze kuqinisekiswe ukusebenza kwawo okuphelele. Izitendi zivame ukushiselwa ngensimbi eyisikwele futhi zenziwe zafanelana nezicaciso zepuleti legwadle. Izicelo ezikhethekile zingase futhi zamukeleke ukuze kuhlangatshezwane nezidingo ezithile zamakhasimende. Ubude besitendi bunqunywa ukujiya kwepuleti legwadle, indawo yokusebenza ngokuvamile ibekwe ngo-800mm ngaphezu komhlaba.
Ukusekela Idizayini Yesitendi:
Isitendi sinezindawo zokuxhumana ezinhlanu nephansi. Amaphuzu amathathu kulawa alungisiwe, kanti amanye amabili ayakwazi ukuguqulwa ukuze aleveli eqinile. Isitendi siphinde sibe namaphuzu amahlanu okuxhumana nepuleti le-granite ngokwalo. Lezi ziyalungiseka futhi zivumela ukucushwa kahle kokuqondanisa okuvundlile. Kubalulekile ukuthi uqale ulungise amaphuzu amathathu okuthintana nawo ukuze udale indawo engunxantathu ezinzile, kulandele amanye amaphuzu amabili wokulungiswa okuncane okunembile.
Isiphetho:
Amapuleti angaphezulu kwe-granite, uma ebhangqwe nesitendi sokusekela esiklanywe kahle, anikeza ukunemba okukhethekile nokuzinza, okuwenza afanelekele imisebenzi yokulinganisa ukunemba okuphezulu. Ukwakhiwa okuqinile kanye nezakhiwo ezinhle kakhulu ze-granite plate kanye nesitendi sayo esisekelayo kuqinisekisa ukusebenza kwesikhathi eside ezinhlelweni ezihlukene zezimboni.
