Kiʻekiʻe Kiʻekiʻe New Diesel Injector Nozzle DLLA150P59 0433171059 0 433 171 059 Common Rail Injector Nozzle no nā ʻāpana ʻāpana injector

Ka nānā ʻana i ke kumu i paʻa ai ka nozzle injector i loko o nā injectors. (mahele 1)

1 Ka hōʻoia ʻana o nā mea hoʻāʻo

Ma o ka nānā ʻana i nā kumu kūpono no ka hoʻopili ʻana i ka hui nozzle needle valve, ua hoʻoholo ʻia e hana i kahi ʻano o ka nānā ʻana a me ka nānā ʻana i ka hui nozzle hewa. ʻO nā mea nānā kiko'ī penei:

1) E nānā i ka ʻae like ʻana o ka hui ʻana a me ke kūpono o ka ʻili o ka noho valve needle;

2) E ana hou i ka poepoe, cylindricity, roughness, and surface hardness of the needle valve ma hope o ka hoʻomaʻemaʻe (wehe ʻana i ka ʻōpala o ka ʻili, etc.);

3) Hoʻomaʻemaʻe (wehe i ka ʻōpala o ka ʻili, etc.)

4) Hoʻokaʻawale i ka pahu nila a me ka nozzle, a hana i ka nānā ʻana i ka kala ma ka ʻili o ka pahu kui a me ka nozzle;

5) E hoʻouna i ka pūnana nila a me ka nozzle no ka nānā ʻana i ka metallographic, e ana i ka ratio haumia.

2 hopena ho'āʻo
2.1 Hōʻike ʻia nā hopena ana o ke anawaena o waho o ka ʻili kūpono o ka nila a me ke anawaena o loko o ka ʻili kūpono nozzle ma ka Papa 1. Ma waena o lākou, ʻaʻole i hoʻokomo ʻia nā ʻāpana like me ka helu HHM. Mai ka ʻikepili ana, hiki ke ʻike ʻia ʻoi aku ka nui o nā āpau kūpono o nā pūʻulu ʻelua o nā huila ma mua o ka waiwai o ka hoʻolālā, ka pōʻai o ka puka o loko o ka valve needle a me ka nozzle me ka helu peʻa HD e hoʻokō i nā koi hoʻolālā. a me ka poepoe o ka puka o loko o ka nila a me ka nozzle me ka helu hoailona HHM mamua o ka manao Koi. He koʻikoʻi ka ʻili o ka valve nila me ka helu kila HD, a ʻaʻole hiki ke nānā ʻia ka ʻili kūpono. Hōʻike ʻia ke kūlana kikoʻī ma Figure2.

ʻOi aku ka laulā o ka ʻili kūpono o ka pahu nila me ka helu HHM, me ka bandwidth ma kahi o 2mm, e like me ka hōʻike ʻana ma ke Kiʻi 3 (e ʻeleʻele ka ʻili o ka male ma hope o ka lepo iki ʻana o ka lua, no laila hiki iā ʻoe ke nānā i ke kūlana kūpono). Eia kekahi, ua ana ka huina cone ma ka hope mua o ka valve needle, a ʻo ka hoʻolālā e koi i kahi kihi cone o 91 ° ± 5 '. ʻO ka huina nila o ka helu sila sila e hoʻomaka ana i ka HHM ʻo 91 ° 1 ′, a ʻo ke kihi o ka nila o ka helu kila kila e hoʻomaka ana HD ʻo 91 ° 2 ′, ʻo ia mau mea ʻelua e hoʻokō i nā koi o nā kiʻi.
