Kubaka sima hakoreshejwe imashini bimaze imyaka myinshi bigeragezwa kandi bigatezwa imbere mu Bushinwa, ariko nta ntambwe igaragara yatewe. Uretse gushidikanya kw'abantu ku mpinduka zikomeye bubaka sima bufite mu buryo gakondo bwo kubaka, impamvu nyamukuru ni uko mu buryo gakondo, sima ivanze aho hantu ishobora gutera kuziba imiyoboro n'indi mishinga mu gihe cy'ubwubatsi bushingiye ku mashini bitewe n'ibibazo nk'ingano y'ibice n'imikorere. Amakosa ntagira ingaruka gusa ku iterambere ry'ubwubatsi, ahubwo yongera imbaraga z'ubwubatsi, ibyo bitera ubwoba bw'abakozi ku ngorane kandi bikongera ingorane zo guteza imbere ubwubatsi bushingiye ku mashini.
Mu myaka ya vuba aha, nyuma yo gushinga inganda nini zikora imashini zivanze n’amazi mu gihugu hose, ubuziranenge n’ubudahangarwa bya sima byaremewe. Ariko, sima ivanze n’amazi itunganywa kandi igakorwa n’inganda. Ku bijyanye n’ibikoresho fatizo byonyine, igiciro kigomba kuba kiri hejuru y’icyo kuvanga aho hantu. Niba gusigwa n’intoki bikomeje, nta nyungu bizagira ugereranije n’izikora imashini zivanze aho hantu, kabone n’iyo haba hari ibihugu Bitewe na politiki yo “guhagarika amafaranga”, inganda nshya zikora imashini zivanze n’amazi ziracyagorwa no kubona ibizitunga, amaherezo zigahomba.
Incamake y'imikorere irambuye ya mortilage ikoreshejwe imashini
Ugereranyije na mortilage isanzwe ivangwa aho ikorerwa, itandukaniro rikomeye rya mortilage ikoreshwa mu mashini ni ikoreshwa ry'uruhererekane rw'ibintu bivanze nka hydroxypropyl methyl cellulose ether bishobora kunoza imikorere ya mortilage, bityo mortilage nshya ivanze ikaba nziza, ifite ubushobozi bwo kubika amazi menshi, kandi igakomeza gukora neza nyuma yo kuyikoresha intera ndende no kuyikoresha mu burebure. Inyungu yayo nini iri mu buryo bwo kuyikora neza no kuyitunganya neza nyuma yo kuyikoresha. Kubera ko mortilage ifite umuvuduko munini mu gihe cyo kuyitera, ishobora gufata neza substrate, bishobora kugabanya neza ikibazo cyo gupfuka no kwangirika.
Nyuma y’ibizamini bihoraho, byagaragaye ko mu gihe utegura sima ikoreshwa mu mashini, koresha umucanga wakozwe n’imashini ufite ingano ntarengwa ya 2.5mm, ifu y’amabuye iri munsi ya 12%, kandi ufite intera ikwiye, cyangwa ingano ntarengwa ya 4.75mm n’ingano y’ibyondo iri munsi ya 5%. Iyo igipimo cyo kubika amazi muri sima nshya ivanze kigenzurwa hejuru ya 95%, agaciro k’ubuziranenge kagenzurwa kuri 90mm, kandi igihombo cy’amasaha 2 kikagenzurwa muri 10mm, sima ifite imikorere myiza yo kuvoma no gutera, kandi isura ya sima yakozwe ikaba nziza kandi isukuye, urusobe rurangana kandi rukungahaye, nta gucika, nta gupfuka cyangwa kwangirika.
Ikiganiro ku byongewemo ibintu bivanze mu imashini ikoresha imashini
Uburyo bwo kubaka imashini itera amazi irimo kuvanga, kuvoma no gutera amazi. Dushingiye ku kuba iyi fomura ikwiye kandi ubwiza bw'ibikoresho fatizo bwujuje ibisabwa, akazi gakomeye k'imashini itera amazi ni ukunoza ubwiza bw'imashini itera amazi kandi ikanoza imikorere y'imashini itera amazi. Kubwibyo, imashini itera amazi igizwe n'ibikoresho bitwara amazi n'ibikoresho bitera amazi. Hydroxypropyl methylcellulose ether ni igikoresho cyiza cyo kubika amazi, gishobora kongera ubukana bwa mashini gusa, ahubwo kinanongera cyane ubusugire bw'imashini no kugabanya gutandukanya no kuva amaraso mu gihe kimwe. Imashini itera amazi muri rusange igizwe n'ibikoresho bitera umwuka n'ibikoresho bigabanya amazi. Mu gihe cyo gukurura imashini itera amazi, hashyirwaho uduce twinshi tw'umwuka duto kugira ngo habeho ingaruka z'umupira, bishobora kugabanya ubukana hagati y'uduce tw'ibice bivanze no kunoza imikorere y'imashini. Mu gihe cyo gutera imashini ikoresheje imashini, guhindagurika kwa micro-vibration guterwa no kuzunguruka kwa pompe itwara vis bizatuma imashini iri mu gikoni ihinduka mu buryo bworoshye, bigatuma imashini iba nto mu gice cyo hejuru n'imashini iba nini mu gice cyo hasi, ibyo bikaba byatuma imiyoboro ifunga iyo imashini irimo gukora, kandi nyuma yo gushushanya, ubwiza bwa imashini ntibuba bumwe kandi bushobora kuma no kwangirika. Kubwibyo, mu gihe cyo gushushanya inyongera zivanze zo gutwika imashini, hagomba kongerwamo bimwe mu bikoresho bihamye kugira ngo bigabanye umuvuduko wo gukuraho imashini.
Ubwo abakozi bakoraga igerageza rya mortilage yakoreshejwe imashini, igipimo cy'inyongeramusaruro cyari 0.08%. Mortilage ya nyuma yari ifite ubushobozi bwo gukora neza, imikorere myiza yo gupompa, nta kintu cyacitse mu gihe cyo gutera, kandi ubugari ntarengwa bwo guteramo kamwe bwashoboraga kugera kuri 25px.
