TL;DR —Ma OEM a ma trailer a EU ndi ogulitsa ma brake system awo a tier-1 amafuna kuti gawo lililonse la brake valve lochokera kunja kwa European Union likhale ndi satifiketi yovomerezeka ya ECE R13. ECE R13 imakhudza zofunikira zovomerezeka za mtundu wa brake system yamagalimoto m'chigawo cha UNECE, kuphatikiza ma valve a pneumatic brake, ma valve a solenoid, ndi ma valve otumizirana omwe amagwiritsidwa ntchito mu ma trailer air brake system. Njira yovomerezekayi imafuna kuti wopanga apambane mayeso azinthu (ISO 9227 neutral salt spray test — maola osachepera 480 pazinthu za pneumatic), kuyesa kogwira ntchito (nthawi yoyankha pansi pa masekondi 0.4 a solenoid valve pa 8.5 bar), ndi kuwunika kogwirizana ndi kupanga (COP) pamalopo ndi ntchito yaukadaulo yovomerezedwa ndi UNECE. Valavu ya brake yopanda satifiketi yovomerezeka ya ECE R13 si yololedwa kuyiyika pa brake yomwe idalembetsedwa koyamba m'maiko omwe ali mamembala a EU kapena EEA. Nkhaniyi ikufotokoza zofunikira za satifiketi, njira yoyesera, ndi zomwe ndaphunzira podutsa ma audit a ECE R13 a ma valve a solenoid ndi ma valve a brake omwe Fangjie amapereka kwa opanga ma trailer aku Europe.
Makampani opanga ma trailer aku Europe ali ku Germany (Schmitz Cargobull, Kögel), Poland (Wielton), ndi Netherlands (Burgers, Broshuis). Ma OEM awa amasonkhanitsa ma semi-trailer pafupifupi 200,000, ma trailer apakati-axle, ndi ma trailer apadera pachaka pamsika wa EU. Chigawo chilichonse cha pneumatic brake chomwe chimayikidwa pa trailer - kuyambira valavu yayikulu ya brake mpaka valavu yaying'ono kwambiri ya solenoid - chiyenera kukhala ndi satifiketi ya ECE R13 kuti chigwiritsidwe ntchito pama trailer olembetsedwa m'maiko 56 omwe agwirizana ndi UNECE, kuphatikiza mayiko onse 27 omwe ali mamembala a EU. Ma valavu a brake ochokera ku kampani ya ku China yopanda satifiketi ya ECE R13 akudziika pachiwopsezo cholembetsa - valavuyo siyingalembetsedwe kuti igwiritsidwe ntchito pamsewu mpaka zigawo za brake zitasinthidwa ndi zofanana ndi zomwe zatsimikiziridwa.
Ndakhala ndikuyang'anira njira yopezera satifiketi ya zinthu za Fangjie zoyendetsera ma brake valve kuyambira mu 2018 ndipo ndadutsa mayeso a ECE R13 a ma solenoid valves, ma relay valves, ndi ma brake chambers. Nkhaniyi ikufotokoza zomwe ma EU trailer OEMs ayenera kutsimikizira akamagula ma brake valves ochokera ku China.

Zomwe ECE R13 Ikuphimba - Kukula ndi Mayeso Ofunika
ECE R13 ndi lamulo la UNECE la malamulo ofanana okhudza kuvomereza magalimoto pankhani ya kuletsa mabuleki. Lamuloli limakhudza dongosolo lonse la mabuleki agalimoto, koma likagwiritsidwa ntchito pa satifiketi ya gawo (monga "gawo laukadaulo losiyana"), limafuna kuti wopanga ma valavu a mabuleki awonetse kuti akutsatira zofunikira zinazake zogwirira ntchito. Mayeso asanu ofunikira a gawo la valavu ya mabuleki ya pneumatic pansi pa ECE R13 ndi awa:
| Mayeso | Buku Lovomerezeka | Kufunika kwa Valve ya Brake ya Pneumatic | Nthawi Yoyesera |
|---|---|---|---|
| Kukana dzimbiri | ISO 9227 / ECE R13 Annex 6 | Palibe kuwonongeka kwa ntchito pambuyo pa maola 480 mu kupopera mchere wopanda mankhwala — valavu iyenera kugwira ntchito bwino ndipo malo akunja sayenera kuwonetsa dzimbiri lofiira lomwe limalowa mu chitsulo choyambira. | Maola 480 (masiku 20) |
| Nthawi yoyankhira (valavu ya solenoid) | ECE R13 Annex 10, ndime 2.2.5 | Valavu iyenera kufika 75% ya mphamvu yogwiritsira ntchito mkati mwa masekondi 0.4 pa mphamvu ya 8.5 bar supply pressure ndi 20°C. | Kuyezedwa m'magawo asanu otsatizana |
| Kutayikira kwamkati | ECE R13 Annex 10 | Kutayikira kwamkati pa mpando wa valavu sikuyenera kupitirira 50 cm³/min pa 8.5 bar (yoyezedwa ndi flow meter pa doko lotulutsa utsi) | Kuyezedwa pa mfundo zitatu zopanikizika (2.5, 6, ndi 8.5 bar) |
| Kuthamanga kwamphamvu | ISO 6301 / ECE R13 | Thupi la valavu liyenera kupirira kuthamanga kwakukulu kwa ntchito kwa 4 × (34 bar ya valavu yopumira ya 8.5 bar) popanda kuphulika kapena kusinthika kosatha.SAE J1409njira zoyesera kuthamanga kwa ma valve a pneumatic | Kuyesa kamodzi mpaka kuwonongeka pa chitsanzo chimodzi pa gulu lililonse |
| Kupirira kwa kuthamanga kwa kuthamanga | ECE R13 Annex 10, ndime 2.2.7 | Ma circuits 10 miliyoni pakati pa 0 bar ndi 8.5 bar pa 1 Hz — valavu iyenera kusunga nthawi yotayikira ndi nthawi yoyankha itatha kuyiyendetsa | Ma cycle 10 miliyoni (pafupifupi miyezi 2.5 yoyesera kosalekeza pa chipangizo choyesera mpweya) |
Valavu ya brake yomwe yapambana mayeso onse asanu imalandira satifiketi yovomerezeka ya ECE R13 yoperekedwa ndi ntchito yaukadaulo yovomerezeka ndi UNECE. Nambala yovomerezeka imasindikizidwa kapena kulembedwa ndi laser pa thupi la valavu (bwalo lokhala ndi chilembo "E" lotsatiridwa ndi nambala ya dziko - mwachitsanzo, E9 ya Spain - ndi nambala yovomerezeka). Satifiketiyo ndi yovomerezeka pazigawo zonse zopangira zomwe zimakwaniritsa kapangidwe kovomerezeka ndipo zimapangidwa motsatira dongosolo lomwelo.
Njira Yotsimikizira - Zomwe Wogulitsa Wachi China Ayenera Kumaliza
Njira yotsimikizira ya ECE R13 ya wopanga ma brake valve aku China imatsatira ndondomeko ya magawo atatu. Gawo 1: Kuyang'aniridwa koyamba kwa fakitale ndi bungwe laukadaulo. Utumiki waukadaulo wovomerezeka ndi UNECE (mongaTÜV Rheinland, DEKRA, kapena IDIADA) imatumiza woyang'anira ku fakitale yopanga zinthu ku China. Woyang'anira amawunikanso njira yoyendetsera khalidwe (ISO 9001 kapena IATF 16949), satifiketi yoyesera zinthu, zolemba zowunikira zida zopangira, ndi njira yotsatirira. Kuwunika kumeneku kumawononga $3,000–$5,000 ndipo kumatenga masiku awiri pamalopo.
Gawo 2: kuyesa zitsanzo ku labotale yautumiki waukadaulo. Wopanga amatumiza zitsanzo 12 za mtundu wa valavu ya mabuleki kuti zitsimikizidwe ku labotale. Zitsanzozo ziyenera kuchokera ku mtundu wokhazikika wopanga - zitsanzo za prototype zopangidwa ndi ulamuliro wapadera wololera sizilandiridwa. Labotale imayesa zitsanzozo poyerekeza ndi zofunikira zisanu zomwe zili patebulo pamwambapa. Mtengo woyesera wa mtundu umodzi wa valavu ya solenoid ndi $8,000–$15,000, kutengera kuchuluka kwa mayeso ofunikira komanso mtengo wa labotale pa ola limodzi. Ntchito zaukadaulo mongaATIC imapereka ntchito zololeza mabuleki a ECE R13 komanso zovomerezeka ndi mtundu wa mathireyilazomwe zimakhudza njira yonse yofunsira satifiketi kwa opanga aku China. Kuyesaku kumatenga miyezi 3-4 kwa chitsanzo chomwe chimapambana mayeso onse pa nthawi yoyamba yoperekedwa - nthawi yayitali ngati kulephera kwa mayeso kumafuna kusintha kapangidwe ndi kuzungulira koyesanso.
Gawo 3: Kuwunika kwa kupanga mogwirizana ndi dongosolo (COP). Pambuyo poti mtundu wa chilolezo chaperekedwa, ntchito yaukadaulo imachita kafukufuku wa COP miyezi 12-24 iliyonse kuti itsimikizire kuti mayunitsi opanga akupitilizabe kukwaniritsa kapangidwe kovomerezeka ndi mulingo wabwino. Kuwunika kwa COP kumakhudza gawo lomwelo monga kuwunika koyambirira, kuphatikiza kuyang'ana zolemba zopangira kuti zitsimikizire kuti palibe kusintha kosaloledwa kwa kapangidwe komwe kwachitika. Mtengo wa pachaka wa kafukufuku wa COP ndi $2,000–$4,000 pakuwunika kulikonse. Ku Fangjie, tasunga satifiketi yathu ya ECE R13 ya ma solenoid valves ndi ma relay valves kuyambira 2019, ndi ma COP audits apachaka omwe adutsa popanda kusagwirizana kwakukulu mu ma audits 5 otsatizana.
Kuphatikizana kwa ABS/EBS — Kusiyana Kofanana kwa Zolemba
Ma OEM a ma trailer a EU amafotokoza kwambiri za EBS (Electronically controlled Brake System) kapena ABS (Anti-lock Braking System) pa ma trailer atsopano. Dongosolo la EBS limagwiritsa ntchito ma valve a solenoid ngati ma modulator okakamiza - EBS ECU imapatsa chizindikiro valavu ya solenoid kuti iwonjezere, igwire, kapena ichepetse kuthamanga kwa ma brake m'chipinda chilichonse cha ma brake payokha panthawi ya braking. Valavu ya solenoid ya EBS siyenera kungopambana mayeso a ECE R13 pneumatic komanso iyeneranso kupambana mayeso a electromagnetic compatibility (EMC) pa ECE R10 iliyonse - valavuyo siyenera kutulutsa kusokoneza kwa electromagnetic kupitirira malire ndipo siyenera kulephera kugwira ntchito ikakumana ndi minda ya electromagnetic yowala mpaka 30 V/m mu 20 MHz mpaka 1,000 MHz frequency range.
Kusiyana kwa zikalata komwe ndimaona nthawi zambiri mwa ogulitsa ma brake valve aku China omwe amanena kuti ECE R13 ikutsatira malamulo ndichakuti ali ndi satifiketi yovomerezeka ya pneumatic performance (mayeso a dzimbiri, kutuluka kwa madzi, ndi kupirira) koma alibe zikalata zovomerezeka za ECE R10 EMC za magetsi a solenoid valve. Valavu ya solenoid yomwe ili ndi satifiketi ya ECE R13 koma osati R10 siyingagulitsidwe mwalamulo ngati valavu yowongolera kuthamanga kwa EBS ya tela ya EU - zikalata zovomerezeka za tela ya OEM (malinga ndi EU Whole Vehicle Type Approval kapena WVTA) zimafuna satifiketi ya ECE R10 ya gawo lililonse la brake lolamulidwa ndi magetsi. Yankho ndikupempha phukusi lonse la satifiketi (R13 + R10) kuchokera kwa ogulitsa musanayike oda. Ku Fangjie, ziphaso zonse ziwiri zili m'zolemba zathu zovomerezeka za solenoid valve.

Kuti mudziwe mitundu yonse ya ma valve a mabuleki ndi ma valve a solenoid omwe timapereka ndi satifiketi ya ECE R13, onani tsamba lawebusayiti.tsamba la malonda a valavu ya brakePazida zamakina opumira mpweya zomwe zili kunja kwa ma valve,tsamba lazinthu za chipinda chosungira mabulekiZimaphimba zipinda zamabuleki a masika ndi zipinda zamabuleki zogwirira ntchito zomwe zimakwaniritsa dongosolo la mabuleki a mpweya wa thirakitala.
ECE R13 ndi ISO 9001 Quality Interface — Zolemba Zomwe Kuwunika Kumafuna
Kuwunika kwa ECE R13 COP ndi kuwunika kwa ISO 9001 kuyang'anana pamlingo koma sikofanana. Wowunika wa COP amayang'ana kwambiri mzere wopanga ma brake valve makamaka - osati fakitale yonse. Zolemba zomwe wowunika wa COP amawunika ndi izi: tchati cha kayendedwe ka brake valve assembly process (ziyenera kuwonetsa siteshoni iliyonse yosonkhanitsira ndi malo owunikira), zolemba za torque tool calibration za solenoid valve body screws (zomangira za solenoid housing ziyenera kukokedwa mpaka 8±0.5 Nm, ndipo torque wrench iyenera kuyesedwa miyezi itatu iliyonse ndi satifiketi yowunikira yomwe ingatsatidwe ku muyezo wadziko lonse), zolemba zoyeserera zogwira ntchito za valavu iliyonse yopangidwa (choyimira mayeso chiyenera kulemba nthawi yoyankha, kutuluka kwamkati, ndi kukana kwa coil pa unit iliyonse, ndipo zolemba ziyenera kusungidwa kwa zaka 10 motsatira malamulo a ECE R13), ndi zolemba zowongolera zinthu zosagwirizana - valavu iliyonse yomwe yalephera mayeso ogwirira ntchito iyenera kulekanitsidwa, chifukwa cha kulephera kufufuzidwa, ndi zomwe zachitika pokonza.
Ku Fangjie, timasunga fayilo yosiyana ya mbiri ya khalidwe la mzere wopanga wa ECE R13 yomwe siili yogwirizana ndi dongosolo lonse la kasamalidwe ka khalidwe la ISO 9001. Buku la malangizo a khalidwe la mzere wa ECE R13 limalemba mayeso aliwonse oyendera kuthamanga kwa mphamvu, mayeso aliwonse oyeserera kuthamanga kwa mpweya, ndi zomwe zapezeka mu kafukufuku wa COP. Wofufuza wa ISO 9001 amawunikanso QMS yonse koma samayang'ana zolemba za ECE R13 - ndipo mosiyana, wofufuza wa COP amawunika zolemba za mzere wa ECE R13 zokha. Ndikupangira kuti ma OEM a ma trailer a EU apemphe ogulitsa awo aku China kuti apereke gawo laposachedwa la lipoti la COP lomwe likukhudza mzere wopanga ma solenoid valve, makamaka gawo losagwirizana - palibe kusagwirizana kwakukulu ndipo osapitirira ziwiri zazing'ono zosagwirizana mu kafukufuku wa COP womaliza ndiye muyezo wovomerezeka womwe ndimagwiritsa ntchito pakuwunika kwa Fangjie kwa ogulitsa athu opitilira.
