Diesel Injector Fuel Injector 03L130277b 5ws40539 A2c59513554 Siemens no Audi Noho Skoda VW

Cavitation Loko High-Pressure Optical Transparent Fuel Injector Nozzles(MĀhele 5)

No ka nānā ʻana, ua hoʻohana ʻia ke kaomi injection o ka mīkini maoli (800 bar) ma ke ʻano he palena palena i nā ʻili o loko o ka ʻāpana nozzle acrylic.Ma muli o ka hāʻule pinepine ʻana o nā mea palupalu i ka haʻalulu, ua hoʻohui ʻia nā ʻāpana sapphire i ka hoʻolālā e hoʻopaʻa i ka nozzle mai waho a e hōʻemi i nā ikaika tensile ma nā ʻili o loko.No ka mea, aia ma waho o ka nozzle nā ​​paʻi, pono e hoʻohana ʻia kahi mea ʻike maka no ka hana ʻana.

Ua koho ʻia ʻo Sapphire ma muli o kona lōʻihi kiʻekiʻe.Ma kahi ʻano, ua hoʻopili kēia i ka sapphire i nā ʻāpana amo o ka nozzle, ʻoiai ʻo ka ʻāpana i hoʻopili pololei ʻia ai ke kaomi i hana ʻia me ka acrylic.

ʻO ka hoʻolālā hope loa me 3 sapphire clamps, i hana ʻia a hui pū ʻia, hōʻike ʻia ma ka Figure 1. ʻO ka nui o waho o ka nozzle he 21.5 mm i ka nānā ʻana ma ka Figure 1 a me 6.75mm ma ke ala kū.Hoʻohana ʻia nā sila O-ring ma kēlā me kēia ʻaoʻao o ka nozzle.

3 Nā hualoaʻa a me ke kūkākūkā

Ua hoʻāʻo ʻia kēia hoʻolālā me ka wahie diesel i hoʻolako ʻia e kahi pāpaʻi piston reciprocating pāʻoihana me nā pae 3, i alakaʻi ʻia e kahi kaʻa uila nui.Ua hoʻonohonoho ʻia ka lōʻihi o ka injection mua i 250ms, akā ua hōʻike ʻia nā ana ʻana o ka puʻupuʻu puʻupuʻu ʻaʻole hiki i ka pamu ke hoʻomau i ke kaomi kauoha no ka manawa holoʻokoʻa.Ma kahi o 100ms ka hopena o ka manawa, a ua emi mālie ke kaomi ʻana i kēia manawa.

Ua hopu ʻia ke kahe i loko o ka nozzle ma kahi hoʻonohonoho transillumination me kahi kāmele Phantom V1210 kiʻekiʻe.No ka mea, aia ka ambient ma ke kua o ka lewa, ua maʻalahi ke kahe o ka puka.Hōʻike ʻia ke kiʻi hōʻike me ke kaomi injection o 350 bar ma ke Kiʻi 2. Ua hāʻawi pū ʻia kahi wikiō piha o ka kahe o loko a me ka orifice kahe a me ka ʻāina hoʻokumu ʻia i kēia kūlana kahe.Aia kēia kūlana kahe ma kahi helu Reynolds ma kahi o 85,000.
