Aya makuru muri rusange akubiyemo gusa ingingo z'ingenzi zo gukoresha neza imigozi y'iminyururu. Bishobora kuba ngombwa kongeramo aya makuru ku bikorwa byihariye. Reba kandi amabwiriza rusange ku bijyanye no kugabanya umutwaro, atanzwe ku rupapuro rukurikira.
IBYOSE:
Reba imigozi y'urunigi mbere yo kuyikoresha.
● Kubara imbaraga zo gufunga zikenewe mu buryo bwatoranijwe bwo kugabanya umutwaro.
● Hitamo ubushobozi n'umubare w'imigozi y'urunigi kugira ngo utange nibura imbaraga z'imigozi zibazwe
● Menya neza ko aho imodoka ihambiriye cyangwa umutwaro wayo bifite imbaraga zihagije.
● Rinda imigozi y'urunigi ku mpande nto za radii cyangwa ugabanye ubushobozi bwo kuyifata hakurikijwe amabwiriza y'uwakoze.
● Menya neza ko imigozi y'urunigi ihambiriwe neza.
● Witondere igihe urekura imigozi y'urunigi mu gihe umutwaro wabaye udakomeye kuva aho imigozi ishyizwe.
NTUZIGERE:
● Koresha imigozi y'umunyururu kugira ngo uterure umutwaro.
● Ipfundo, hambira cyangwa uhindure imigozi y'umunyururu.
● Imigozi yo gushyiramo iminyururu myinshi.
● Koresha imigozi y'urunigi ku nkombe isongoye nta kurinda impande cyangwa ngo ugabanye ubushobozi bwo kuyifata.
● Shyira imigozi y'urunigi ku miti itabanje kugisha inama umucuruzi.
● Koresha imigozi y'iminyururu ifite imigozi yangiritse, tensioner yangiritse, terminal fittings yangiritse cyangwa indangamuntu ibura.
Guhitamo uburyo bukwiye bwo gukurura iminyururu
Igipimo ngenderwaho cy’imigozi y’urunigi ni BS EN 12195-3: 2001. Bisaba ko urunigi rukurikiza EN 818-2 kandi ibice biruhuza bigakurikiza EN 1677-1, 2 cyangwa 4 uko bikwiye. Ibice bihuza n’ibigabanya bigomba kugira igikoresho gikingira nk’urukingo rw’umutekano.
Izi ngamba ni iz'ibintu byo mu rwego rwa 8. Bamwe mu bakora ibintu batanga kandi ibipimo byo hejuru, ingano ikurikije ingano, bifite ubushobozi bwo gufunga cyane.
Imigozi y'iminyururu iboneka mu bushobozi n'uburebure butandukanye kandi mu buryo butandukanye. Imwe ni ingirakamaro muri rusange. Indi igenewe gukoreshwa mu buryo bwihariye.
Guhitamo bigomba gutangirira ku isuzuma ry'imbaraga zikora ku mutwaro. Imbaraga zo gukurura zikenewe zigomba kubarwa hakurikijwe BS EN 12195-1: 2010.
Hanyuma reba niba aho imodoka ihambiriye cyangwa umutwaro wayo bifite imbaraga zihagije. Niba bibaye ngombwa shyiramo imigozi myinshi kugira ngo imbaraga zikwirakwizwe mu bice byinshi byo kuyihambiriraho.
Imigozi y'iminyururu igaragazwa n'ubushobozi bwayo bwo kuyihambira (LC). Igaragazwa muri daN (deca Newton = 10 Newtons) Iyi ni imbaraga zingana n'uburemere bwa 1kg.
Gukoresha imigozi y'urunigi mu mutekano
Menya neza ko icyuma gitera imbaraga gishobora kwifata neza kandi kidapfundika ku nkombe. Menya neza ko umunyururu udapfundika cyangwa ngo upfundike kandi ko ibikoresho byawo bifatanye neza n'ingingo zo gufunga.
Ku bice bibiri byo gufunga, menya neza ko ibice bihuye.
Menya neza ko umugozi urinzwe impande zito kandi zisongoye hakoreshejwe ibikoresho byo gupakira cyangwa ibikingira impande bikwiye.
Icyitonderwa: Amabwiriza y'uwakoze ashobora kwemerera gukoreshwa ku nkengero nto z'umurambararo mu gihe ubushobozi bwo gufunga bugabanutse.
Igenzura n'ububiko biri mu kazi
Imigozi y'iminyururu ishobora kwangirika bitewe no gufunga umunyururu ku nkengero nto z'umurambararo nta burinzi buhagije bw'inkombe. Ariko kwangirika gushobora kubaho ku bw'impanuka bitewe n'umutwaro ugenda mu nzira, bityo bikaba ngombwa kugenzura mbere yo gukoresha buri gihe.
Imigozi y'urunigi ntigomba gushyirwamo imiti, cyane cyane aside ishobora gutera hydrogen kugabanuka. Iyo habayeho kwandura ku buryo butunguranye, imigozi igomba gusukurwa n'amazi meza kandi ikareka ikakama mu buryo busanzwe. Imiti idakomeye izarushaho gukomera iyo ihumeka.
Imigozi y'iminyururu igomba kugenzurwa kugira ngo harebwe ibimenyetso bigaragara by'ibyangiritse mbere yo kuyikoresha. Ntugakoreshe imigozi y'iminyururu niba hari inenge zikurikira zibonetse: ibimenyetso bitagaragara; imigozi igoramye, miremire cyangwa ifite imigozi, ibice bihuza cyangwa bifite imigozi, imigozi y'umutekano idakora neza cyangwa ibura.
Imigozi y'umunyururu izagenda ishira uko igihe kigenda gihita. LEEA isaba ko igomba gusuzumwa n'umuntu ubishoboye nibura buri mezi 6 kandi hagakorwa inyandiko y'ibyavuye mu isuzuma.
Imigozi y'iminyururu igomba gusanwa n'umuntu ubishoboye.
Kugira ngo bibikwe igihe kirekire, ahantu ho kubika hagomba kuba humutse, hasukuye kandi hatarimo umwanda uwo ari wo wose.
Amakuru arambuye atangwa muri:
