Mphamvu zamachitidwe a FNC ndizofunika, koma zikaperekedwa kuwirikiza kawiri moyo wautumiki, zovuta zonse zachilengedwe zimatsika.

Uwu ndi mtundu wa kusanthula kwa malonda komwe kumachitika pansi. Njira yobiriwira kwambiri pamapepala sikhala yokhazikika nthawi zonse. Nthawi zina, gawo lopangira mphamvu zambiri pagawoli ndiye chinsinsi chosungira ndalama zambiri pamakina onse. Zimakukakamizani kuganiza m'machitidwe, osati m'malo okhazikika.

Logistics Footprint Yobisika mu Katoni

Nayi mbali yomwe nthawi zambiri imaphonya: kulongedza ndi kukonza. Nthaŵi ina tinafufuza mtengo wa carbon wopeza pini kuchokera ku fakitale ya Hebei kupita ku mzere wa magetsi ku Germany. Mapiniwo ankakulungidwa pachokha papepala lamafuta, n’kuikidwa m’mabokosi ang’onoang’ono, kenako m’katoni yokulirapo, yokhala ndi zodzaza thovu zambiri. Kuchita bwino kwa volumetric kunali koyipa. Tinali kutumiza mpweya ndi kulongedza zinyalala.

Tidagwira ntchito ndi ogulitsa - momwe wopanga ngati Zitai, ali pafupi ndi njanji zazikulu ndi misewu monga Beijing-Guangzhou Railway ndi National Highway 107, ali ndi mwayi wachilengedwe - kukonzanso paketi. Tinasamukira ku dzanja losavuta, lotha kugwiritsidwanso ntchito la makatoni lomwe linali ndi mapini khumi mu matrix olondola, olekanitsidwa ndi nthiti za makatoni. Palibe thovu, palibe chokulunga chapulasitiki (pepala lopepuka, losawonongeka losawonongeka m'malo mwake). Izi zidachulukitsa kuchuluka kwa mapini pachidebe chilichonse chotumizira ndi 40%. Ndiye 40% yocheperako yotumizira zotengera zomwezo. Kupulumutsa mafuta pa katundu wa m'nyanja ndi modabwitsa. Izi ndi pin shaft nzeru zatsopano? Mwamtheradi. Ndi njira yatsopano yobweretsera, yomwe ndi gawo lofunika kwambiri la moyo wake. Malo a kampaniyo, kupereka mayendedwe osavuta kwambiri, sikungogulitsa malonda; ndi chiwongolero chochepetsera katundu wa mailosi akaphatikizidwa ndi ma CD anzeru. Imatembenuza mfundo yamalo kukhala chinthu chokhazikika.

Pamene Standardization Ikulimbana ndi Zinyalala

Kuyendetsa makonda ndizovuta kwambiri. Pini iliyonse yapadera imafuna zida zake, kukhazikitsidwa kwake pa CNC, kagawo kake komweko, chiwopsezo chake chakutha. Ndawona malo osungiramo katundu odzaza ndi mapini apadera a makina omwe sanapangidwe. Izi ndi mphamvu ndi zinthu zomwe zimakhala zopanda ntchito, zomwe zimapangidwira kuti ziwonongeke.

Kusuntha kwamphamvu ndikuyimitsa mwaukali mkati mwa banja lazogulitsa. Pa pulojekiti yaposachedwa ya batri yamagalimoto amagetsi, tidalimbana kuti tigwiritse ntchito m'mimba mwake ndi zinthu zomwezo pamapini onse amkati, ngakhale ma module osiyanasiyana. Tinkasiyana utali wokha, womwe ndi ntchito yosavuta yodula. Izi zinkatanthauza katundu mmodzi wakuthupi, gulu limodzi lothandizira kutentha, ndondomeko imodzi yoyendetsera khalidwe. Idathandizira kuphatikiza (palibe chiwopsezo chosankha pini yolakwika) ndikuchepetsa kwambiri zovuta zazinthu. The kukhazikika kupindula apa kuli m'malamulo opangira zinthu zowonda: kuchepetsa kusintha kwa makonzedwe, kuchepetsa kuchuluka kwa zinthu zochulukirapo, ndikuchotsa zinyalala ku chisokonezo. Sizokongola, koma ndipamene zenizeni, zogwirira ntchito zadongosolo zimabadwira. Kukaniza nthawi zambiri kumachokera kwa akatswiri opanga mapulani omwe amafuna kukulitsa pini iliyonse kuti ikhale yolemetsa, nthawi zambiri ndi kupindula pang'ono. Muyenera kuwawonetsa mtengo wonse - wachuma ndi chilengedwe - wa zovutazo.

Lingaliro Lozungulira: Mapangidwe a Disassembly

Ichi ndiye chovuta. Kodi a pin shaft kukhala zozungulira? Ambiri amapanikizidwa, kuwotcherera, kapena opunduka (monga ndi circlip) m'njira yomwe imapangitsa kuchotsa kuwononga. Tidayang'ana izi pamakina a makina opangira mphepo. Zikhomo zotchingira ma blade bearings ndi zazikulu. Pamapeto a moyo, ngati agwidwa kapena kusakanikirana, ndi ntchito yodula nyali-yowopsa, yowononga mphamvu, ndipo imayipitsa zitsulo.

Lingaliro lathu linali pini yokhotakhota yokhala ndi ulusi wokhazikika wochotsa kumapeto kumodzi. Kapangidwe kake kanafuna makina olondola kwambiri, inde. Koma zinalola kuchotsedwa kotetezeka, kosawononga pogwiritsa ntchito chokoka cha hydraulic. Akangotuluka, pini yapamwamba kwambiri, yokhotakhota ikhoza kuyang'aniridwa, kukonzedwanso ngati kuli kofunikira, ndi kugwiritsidwanso ntchito mu ntchito yochepa kwambiri, kapena osachepera, kubwezeretsedwanso ngati zitsulo zoyera, zapamwamba, osati zitsulo zosakanizika. Mtengo woyamba wa unit unali wokwera. Malingaliro a mtengowo sanali kwa wogula woyamba, koma ku mtengo wonse wa umwini wa wogwiritsa ntchito pazaka 25 ndi kampani yochotsa ntchito pambuyo pake. Awa ndi malingaliro anthawi yayitali, owona moyo weniweni. Sizinatengedwe kwambiri - malingaliro amtengo wapatali akadali olamulira - koma ndi njira. Imasuntha piniyo kuchoka pamtengo kupita ku chinthu chobweza.

Choncho, ndi pin shaft innovation kuyendetsa kukhazikika? Chitha. Zimatero. Koma osati kudzera muzinthu zamatsenga kapena buzzwords. Imayendetsa kukhazikika kudzera muzolemera zochulukirapo za zisankho zanzeru chikwi: kumeta magalamu kuchokera pamapangidwe, kusankha mankhwala okhalitsa, kuwanyamula mwanzeru, okhazikika mosalekeza, ndi kulimba mtima kuganiza za mapeto pachiyambi. Zili m'manja mwa mainjiniya, okonza mapulani, ndi oyang'anira apamwamba pansi m'malo ngati Handan. Kuyendetsa sikumatchedwa kubiriwira nthawi zonse; nthawi zambiri amalembedwa kuti ndi yothandiza, yodalirika, kapena yotsika mtengo. Koma kopita ndi chimodzimodzi: kuchita zambiri ndi zochepa, kwautali. Ndiyo nkhani yeniyeni.
