Gukora Valve y'imipira ya Trunnion mu Bushinwa: Inzira y'umuguzi ku batanga serivisi nziza
Niba wigeze gushaka valve zo mu nganda, uzi neza ko “Valves z'umupira wa Trunnion"na"udupira tw'umupira duhindagurika" - nubwo twombi twitwa udupira tw'umupira - ni inyamaswa zitandukanye cyane iyo bigeze ku miyoboro ifite umuvuduko mwinshi kandi minini.
A valve y'umupira w'imashiniumupira wayo ushyirwa hejuru no hasi hakoreshejwe ibyuma, bityo ntusunikirwa imbere n'umuvuduko w'umurongo nk'uko icyuma gifunga umupira kigenda. Ibyo bivuze iki mu bikorwa? Umuvuduko muke wo gukora, gufunga neza kurushaho - cyane cyane mu mirongo ikwirakwiza gazi karemano, mu byuma bitunganya amashanyarazi, no mu zindi serivisi aho urwego rwa 1500 cyangwa urwego rwa 2500 ari byo bisanzwe. Muri ibyo bihe, ibyuma bifunga umupira ni byo byonyine bikoreshwa.
Imiterere y'umupira uhoraho bivuze ko ibizingo by'umusenyi bifite imbaraga kandi umuvuduko urushaho kwiyongera - uko umuvuduko urushaho kwiyongera, niko ibizingo by'umusenyi birushaho gukomera. Inyigisho ni iyoroshye, ariko kumenya ubushobozi bwo kubikoresha neza, guhitamo ibikoresho bikwiye, no gukora isuzuma ryimbitse - niho ikibazo gikomeye kiri, kandi si buri ruganda rw'Abashinwa rushobora kubitanga.
Ubushinwa bwihutiye muri uru rwego. Wenzhou (Zhejiang), Wuxi (Jiangsu), na Tianjin byashinze amatsinda y’inganda zuzuye. Kuva ku gusuka no gukora imashini kugeza ku guteranya no kugerageza, inganda nyinshi zikora ibintu byose mu rugo, zigatanga igihe cy’inyongera kimwe cya kabiri cy’abatanga ibicuruzwa b’i Burayi, akenshi ku giciro cyiza kurushaho.
Ariko icyo ni ikibazo – hari abatanga ibicuruzwa benshi cyane, kandi ubwiza buratandukanye cyane.
Mu myaka mike ishize, twakoranye n'inganda nyinshi zo mu gihugu zikora ibyuma bifunga imipira. Zimwe muri zo zirahumuriza cyane - ibyemezo byazo bya API 6D ni ingirakamaro, raporo z'ibizamini zuzuye, kandi bohereza amashusho y'igenzura ry'abandi mbere yo koherezwa. Abandi ariko, ntibashobora no gutanga uburyo bukwiye bwo gukurikirana ibikoresho, kandi ibyemezo byabo bya NACE MR0175 rimwe na rimwe bikorerwa kuri photoshop.
Iyi nkuru si indi mbonerahamwe ya “Top 10” – ushobora kuyibona amagana kuri interineti. Ahubwo, ndashaka gusangiza inganda nke twakozeho kandi twasanze ari nziza. Ndababwira icyo buri imwe ikora neza, imishinga ikwiriye, n'imbogamizi zo kwitondera.
