Nyob rau hauv xyoo tas los no, cov khoom sib xyaw- cov khoom sib txuas tau nce zuj zus. Piv txwv suav nrog cov hlua hlau hlau nrog cov tungsten carbide txheej txheej- muab ntau tshaj li ob npaug ntawm kev hnav tsis kam-los yog cov saw hlau uas muaj cov hlau tsis muaj steel- thiab- nylon cov qauv sib xyaw, uas zoo sib npaug cov kev xav tau rau kev tiv thaiv corrosion thiab lub teeb yuag.
Kev khiav hauj lwm Load: Rau hnyav-load scenarios (xws li, ib qho saw hlau uas txhawb nqa ntau dua lossis sib npaug li 5 tons), cov hlau alloy yuav tsum raug xaiv; rau lub teeb loads (tsawg dua los yog sib npaug li 2 tons), carbon hlau yuav raug txiav txim siab.
Environmental Corrosivity: Thaum cov av noo ntau tshaj 60% lossis cov xov xwm corrosive tam sim no, stainless hlau lossis hlau alloy (yuav tsum muaj kev tiv thaiv- txheej txheej) yuav tsum tau ua ntej.
Tus nqi-Kev ua tau zoo: Cov hlua hlau carbon steel muaj tus nqi pib qis tab sis lub neej ua haujlwm luv luv (feem ntau Tsawg dua lossis sib npaug li 1 xyoos); alloy steel chains, txawm li cas los xij, tuaj yeem kav 3-5 xyoo, ua rau qis dua - cov nqi sijhawm.
Kev lag luam Standards: Kev lag luam xws li mining thiab tsim hluav taws xob yuav tsum ua raws li MT/T 99-1997 tus qauv, "Scraper Conveyors for Mines." Tsis tas li ntawd, cov saw hlau yuav tsum tau kuaj xyuas tsis muaj kev puas tsuaj (xws li kev tshuaj xyuas cov khoom sib nqus).
