Porogaramu zo gukoresha icyuma kidasesagura amazi

● Amasahani ya AR235 agenewe gukoreshwa mu kwangirika ku rugero ruciriritse aho atanga ubushobozi bwo kwangirika kurushaho ugereranyije n'icyuma cya karuboni.
● AR400 ni ibyuma byiza cyane birwanya kwangirika, bivurwa n'ubushyuhe kandi bigakomeza gukomera. Ubushobozi bwo kubikora no kubitunganya bwarushijeho kuba bwiza.
● AR450 ni icyuma kidapfa gushwanyagurika gikoreshwa mu buryo butandukanye aho imbaraga zirenze AR400 zikenewe.
● Amasahani ya AR500 akwiriye gukoreshwa mu bucukuzi bw'amabuye y'agaciro, mu mashyamba no mu bwubatsi.
● AR600 ikoreshwa ahantu hakoreshwa ibikoresho byinshi nko gukuramo ibikoresho byose, gucukura no gukora indobo n'ibikoresho byangiritse.
Ibyuma birwanya abrasion (AR) bikunze gukorwa mu buryo bwo kuzunguruka. Ubwo bwoko/urwego rw'ibicuruzwa bya plate by'icyuma byakozwe by'umwihariko kugira ngo bikoreshwe igihe kirekire mu bihe bikomeye. Ibicuruzwa bya AR bikwiriye gukoreshwa mu bice bitandukanye nko gucukura amabuye y'agaciro/ubucukuzi, kohereza ibicuruzwa, gucunga no kubaka ibikoresho, no gutwara ubutaka. Abashushanya n'abakora uruganda bahitamo plate y'icyuma ya AR iyo baharanira kongera igihe cyo gukora ibikoresho by'ingenzi, no kugabanya uburemere bwa buri gikoresho gishyirwa mu bikorwa. Inyungu zo gukoresha plate y'icyuma idashira mu bikorwa birimo ingaruka cyangwa kwegerana n'ibikoresho bitera abrasion ni nyinshi cyane.

Ibyuma birwanya ubushyuhe bwinshi muri rusange bitanga ubudahangarwa bwiza bwo kunyerera no gushwanyagurika. Ingano ya karuboni nyinshi mu cyuma yongera ubukana n'ubukomere bw'icyuma, bigatuma kiba ibikoresho byiza byo gukoresha bisaba ubukana bwinshi cyangwa ubukana bwinshi. Birashoboka kugira ubukana bwinshi ukoresheje icyuma gifite karuboni nyinshi, kandi icyuma kizagira ubukana bwiza bwo kwinjira. Ariko, umuvuduko wo kwangirika uzaba wihuta ugereranije n'icyuma gishyushye kuko icyuma gifite karuboni nyinshi kirashwanyagurika, bityo uduce dushobora gushwanyagurika byoroshye hejuru. Kubera iyo mpamvu, ibyuma bifite karuboni nyinshi ntibikoreshwa mu gusaza cyane.
