Iyo tuvuga ibijanye n'ingene imodoka ikora, akenshi twibanda ku nguvu za moteri, uburyo bwo gutwara bufise ubwenge canke uburyo bw'imbere, ariko gake cane twibanda ku vyo vyihishije imbere mu mubiri w'imodoka, nk'"imirongo y'imitsi" - intsinga z'imodoka. Bifatanya igice cose c’umuyagankuba co mu modoka, kuva ku matara, ku bimenyetso gushika ku bikoresho vy’amashanyarazi, bikaba bifasha mu gacerere gukora neza kw’imodoka yose. Kandi inyuma y’iyo mirongo y’imiduga, .SAEstandard ni nk'"umuyobozi w'uburyo" akomeye, asobanura imbibe z'ibikorwa vyayo n'imipaka y'umutekano. Uyu musi, reka duhishure akabanga k’amawaya y’imodoka y’umurongo wa SAE.
None ingingo ngenderwako ya SAE ni iyihe?
Mbere na mbere, bikwiye kugaragara ko .Itegeko rya SAEni ijambo ry'inyongera ry'"Ishirahamwe ry'Abahinga b'Imodoka" aho kuvuga umuhinguzi w'imodoka canke ikimenyetso c'imodoka. SAE yarateguye ingingo ngenderwako zifatanya uruhererekane rwose rw'agaciro k'imodoka, harimwo n'uguhingura, gukora, no kugerageza, kandi ni ishirahamwe rifise ububasha bwinshi mu bijanye n'ingingo mfatirwako mu bijanye n'imiduga kw'isi yose.
Igituma amawaya y’imodoka ategerezwa gukurikiza ingingo ngenderwako za SAE, ahanini biva ku kuntu amashanyarazi y’imodoka atoroshe be n’aho ikorera bikomeye. Amawaya y’imodoka akozwe n’abahinguzi batandukanye yoshobora gukora mu buryo budahuye iyo ata n’itegeko rimwe ritegekanijwe, kuva ku bibazo bitobito vy’amashanyarazi gushika ku bibazo bikomeye nk’ugucika kw’amashanyarazi n’umuriro. Ivyo bituma ingingo za SAE zikora nk'"ikigereranyo" kigaragaza ko amawaya y'imodoka ashobora kwizigirwa mu bihe bitandukanye bikomeye.
Ibikoresho vyo kwikingira: Ubwoko butatu bw’ibikoresho burabereye mu bihe bitandukanye .
Igipande c'ivyuma ni co gihambaye kuruta ibindi vyose "umurongo wa mbere wo kwikingira" ku nsinga z'imodoka. Ikingira umurongo w’imbere w’umuyagankuba ubwoko butandukanye bw’ivyago bishobora gushika mu bidukikije bigoranye vy’ugukoreramwo kw’imodoka, nk’ugushaza kw’ivyuma, ugusenyuka kw’imiti biva ku mavuta n’ibikonjesha, uguhinduka kw’ubushuhe bukaze, ukwinjira kw’ubukonje, n’uguhungabana kw’umuyagankuba. Itegeko rya SAE (Ishirahamwe ry'Abahinga b'Imiduga) ni itegeko rizwi cane-ku bijanye n'imiterere y'imiduga kw'isi yose. Yashizeho insobanuro zitomoye kandi zikomeye z’ubwoko butatu nyamukuru bw’ibikoresho vyo gukingira umuriro bikoreshwa mu gukoresha intsinga z’imodoka. Ubwoko bumwebumwe bumwebumwe bukoreshwa ibikoresho bitandukanye be n’ibiranga ubushobozi, kandi burahindurwa neza kugira ngo bujane n’imibabaro yihariye y’ibidukikije be n’ivyo bikenewe mu gukoresha ibice bitandukanye vy’ikinyabiziga. Ivyo bituma izo nsinga zikora neza kandi zigamara igihe kirekire mu bihe bitandukanye:
1
Igikingira ubushuhe
Igereranywa n’ibikoresho nka PVC, irimwo ubwoko butatu:GPT(intumbero rusangi-), TWP (uruhome rworoshe-), naHDT(igikorwa kiremereye-). Muri izo, ubwoko bwa TWP, kubera ubuhinga bwabwo bufise inkuta ndende-, burashobora kuzigama neza umwanya kandi burakoreshwa cane mu bikoresho vy’amashanyarazi vy’umubiri. Ubwoko bwa HDT buratanga uburinzi bwiza cane bw’ubuhinga bufise igipande gikomeye cane co kwikingira kandi burabereye mu bihe bigoye vy’akazi.
2
Umusaraba-uhuye n'ivyuma vy'ivyuma
Ibikoresho vya polyolefine vyakoreshejwe mu guhuza (nka GXL, TXL, naSXLubwoko) zifise ubushobozi bwo guhangana n'ubushuhe kandi ni zo zihitamwo ku bidukikije vy'ubushuhe bwinshi nk'ibice vya moteri.
3
Ukwikingira ubushuhe
Intsinga z’ubwoko bwa HTS, zikozwe mu gipimo c’ubuhinga buhanitse nk’igikoresho nyamukuru co kwikingira no gupfuka, zifise ubushobozi bwiza cane bwo guhindura ibintu n’ugukomera cane, hamwe n’ugukomera gutangaje iyo zikoreshejwe igihe kirekire. Ivyo bikoresho bidasanzwe bituma iyo nsinga iguma ifise ubutungane bw’imiterere yayo be n’ubushobozi bwayo bwo gukorana n’umuyagankuba naho yoba imaze gusubiramwo gupfukama, gugobeka no kwinyiganza, ata guca ibice, gukomera canke gutakaza ubushobozi bwayo bwo kwikingira. Igituma intsinga za HTS zigaragara cane ni uko zakozwe ku buryo bubereye ibidukikije vy’amashanyarazi mu bikorwa vy’imodoka, bikaba bituma iba ihitamwo ryiza kandi ry’ukwizigirwa ku bikorwa vy’amashanyarazi bisaba guhindura kenshi no guhindura aho ziri -cane cane mu bice vy’umuryango w’imodoka, aho amashanyarazi aguma afungurwa igihe cose, igikoresho gisanzwe ariko gihambaye co gukoresha amawaya y’imodoka gishiraho ibisabwa bikomeye ku guhinduranya amawaya y’amawaya be n’ igihe kirekire-igihe kirekire.
Ni gute wohitamwo amashanyarazi y’imodoka ya SAE akwiye ku bihe bitandukanye?
Igikoresho ca moteri
Kubera ko ari kimwe mu bice vy’imodoka bishushe cane kandi bishobora gushikirwa n’ubushuhe, igice ca moteri gisaba inyishu z’amashanyarazi zikora cane kandi zishobora guhangana n’ubushuhe bwiza cane. Ku bijanye n’aka karere nyamukuru,GXLcankeTXLumusaraba-imirongo ya polyolefine ihuye ikwiye guhabwa ikibanza ca mbere. Ivyo bihimba vy’umubiri bifatanye n’umusaraba bitanga ubushuhe bwiza cane n’ubushobozi bwo guhangana n’ugusambuka, bikaba bihuye neza n’ibidukikije vy’ubushuhe bwinshi kandi bikaba bituma habaho uguhuzwa kw’umuyagankuba kwizigirwa be n’umutekano w’igihe kirekire w’ibihimba vy’imodoka.
Umubiri w'intsinga
Turavye ukuntu ari ibintu bikomeye be n’ukuntu bishobora gukoreshwa mu buryo bwinshi,TWPintsinga z'ubushuhe zifise uruhome rworoshe-zigaragara nk'ihitamwo ryiza ku bikorwa bitandukanye vy'intsinga. Igishushanyo caco c’uruhome rworoshe-kizigama cane umwanya wo gushiramwo, kijanye n’ibinogo vy’ibikoresho bike kandi bipfutse. Hagati aho, igikoresho c’ubushuhe kiragiha ubushobozi bwiza cane bwo kwimenyereza, gishobora gukoreshwa mu bikorwa vyinshi vy’inganda no mu vy’ubuhinga bwa none, kikaba gishobora gushitsa mu buryo bworoshe ibisabwa bitandukanye vyo gukoresha amashanyarazi bifise ubushobozi bwo kwizigirwa kandi bukora neza.
Urugi/igisenge c'izuba
Mu bihe aho ibikoresho vy’umuyagankuba n’imirongo bikoreshwa kenshi, intsinga zihujwe zirasubirwamwo gupfukama, guhinduka no gukomeretswa n’ubuhinga ku buryo budasanzwe, ivyo bikaba bishiraho ibisabwa bikomeye ku bijanye n’ugukomera kwazo kw’imiterere n’uguhinduka kw’imikorere. Intsinga zifise ubushobozi bwiza cane bwo gukomera ni zo zonyene zishobora kwihanganira mwene ukwo gukomeza kwambara ataco zihungabanya ku bijanye n’ugutwara umuyagankuba canke ubutungane bw’imibumbe. Ni co gituma intsinga za HTS zatowe nk’izo guhitamwo.
Uburyo bwo gutangura
Ku bijanye n’ibintu bikomeye vy’ugutanga amashanyarazi menshi mu nganda, mu modoka no mu mazi, guhitamwo inyishu z’amashanyarazi bisaba kwubahiriza cane ingingo ngenderwako z’inganda z’umwuga. Mu buryo bwihariye, intsinga z’amabateri zikomeye-zikozwe kandi zikozwe mu buryo buhuye n’ingingo ngenderwako ya SAE J1127 ni zo zihitamwo zidakenewe.
Ivyo muri kazoza
Ivy’ugukenera intsinga mu bikoresho vy’amashanyarazi vy’imodoka biraguma vyiyongera kubera iterambere ryihuse ry’imodoka nshasha zikoresha inguvu. MuIvyagezwe vya SAEbirashobora guhinduka muri kazoza kugira ngo bishiremwo ibisabwa bikomeye cane bijanye n’uguhuza n’umuyagankuba, ubushuhe bwinshi, n’ugukoresha ibikoresho bikunda ibidukikije-. Ibanga ryo kwongerera ubushobozi abahinguzi b’imodoka n’abazitanga ibihimba vy’imodoka rizoba ari ugukomeza gukurikirana neza ibintu bigenda bihinduka no gutegura imbere y’igihe ivy’ubuhinga.
Akarorero keza k'iciyumviro c'uko "ibintu vy'ido n'ido bigena umutekano" mu bijanye n'imiduga ni ukubaho kw'imirongo y'imiduga ya SAE, yavuye ku murongo umwe mutoyi gushika ku ngingo ngenderwako zitandukanye. Igihe kizoza tuzotangazwa n'ubuhinga buteye imbere buboneka mu modoka, reka tuzigame mu muzirikanyi iyo "mirongo y'ubuzima" yihishije imbere mu mubiri w'imodoka; ni igikorwa cabo co kwizigirwa gitanga icizigiro gikomeye ku rugendo rwose.
