Granite vs. Cast Iron ndi Mineral Casting Beds: Kumvetsetsa Ma Coefficients Okulitsa Matenthedwe ndi Mphamvu Zawo pa Kulondola kwa Chida cha Machine

Pankhani yomanga mabedi a zida zamakina, zida monga granite, chitsulo choponyedwa, ndi kuponyera mchere zimagwiritsidwa ntchito chifukwa chapadera. Chimodzi mwazinthu zofunika kuziganizira posankha zidazi ndi kuchuluka kwa matenthedwe, makamaka m'malo okhala ndi kutentha kosiyanasiyana. Kusiyana kwa ma coefficients okulitsa matenthedwe pakati pa mabedi oponyera chitsulo ndi mchere kumatha kukhudza kwambiri kukonza kolondola kwa zida zamakina m'malo osiyanasiyana otentha.

Cast iron, chinthu chachikhalidwe chomwe chimagwiritsidwa ntchito popanga zida zamakina, chimakhala ndi mphamvu yowonjezera yowonjezera kutentha. Izi zikutanthauza kuti pamene kutentha kumasinthasintha, mabedi achitsulo amatha kukulitsa ndi kutsika, zomwe zimapangitsa kusintha kwa makina. Kumbali ina, kuponyedwa kwa mchere, komwe nthawi zambiri kumapangidwa ndi zinthu monga epoxy resin ndi granite aggregates, kumakhala ndi gawo locheperako lokulitsa kutentha poyerekeza ndi chitsulo choponyedwa. Makhalidwewa amalola mabedi oponyera mchere kuti awonetse kusintha kocheperako potengera kusiyanasiyana kwa kutentha.

Zotsatira za kusiyana kumeneku zimakhala zofunikira kwambiri m'madera omwe kuwongolera kutentha kumakhala kovuta. M'madera otentha kwambiri, kuwonjezereka kwa kutentha kwapamwamba kwachitsulo choponyedwa kungayambitse zolakwika mu makina a makina, zomwe zimakhudza kulondola kwake ndi ntchito yake. Mosiyana ndi zimenezi, mabedi oponyera mchere, omwe ali ndi mphamvu yowonjezera yowonjezera kutentha, amakhala okonzeka bwino kuti azikhala olondola muzochitika zoterezi.

Mosiyana ndi izi, m'malo otsika kutentha, kutsika kwamafuta komwe kumawonjezera kutentha kwa mineral casting kumatha kupangitsa kuti pakhale mawonekedwe olimba poyerekeza ndi chitsulo choponyedwa, zomwe zitha kukhudza kuyankha kwamphamvu kwa chida cha makina komanso kugwetsa kugwedezeka. Kumvetsetsa kusiyana kumeneku ndikofunikira kuti opanga ndi ogwiritsa ntchito asankhe mwanzeru potengera kutentha komwe chida cha makina chidzagwira ntchito.

Pomaliza, coefficient yowonjezera kutentha imagwira ntchito yofunika kwambiri pakusankha zida zamabedi a zida zamakina. Ngakhale kuti chitsulo chachitsulo chakhala chisankhidwe chachikhalidwe, kutsika kwa kutentha kwapansi kwa mchere, nthawi zambiri kumaphatikizapo granite, kumapereka ubwino wosunga zolondola pazigawo zosiyanasiyana za kutentha. Poganizira izi, opanga ndi ogwiritsa ntchito amatha kukhathamiritsa magwiridwe antchito komanso moyo wautali wa zida zamakina pazinthu zosiyanasiyana zogwirira ntchito.
