ʻO ka Pum Pum Diesel maikaʻi maikaʻi 3 418 403 005 3403-005 Nā ʻāpana Pump Diesel 3418403005 3403005 no ka ʻenekini Pump

ʻO ka hana o ka pahu hoʻoheheʻe wahie e hāʻawi i ka wahie kiʻekiʻe i ka wahie injector i ka manawa kūpono a me ke ʻano e like me nā kūlana hana o ka mīkini diesel a me ke kauoha hana o ka cylinder.

1.Multi-cylinder kaʻa diesel wahie injection pump pono e hoʻokō i kēia mau koi

(1)) Ua like ka nui o ka aila i hāʻawi ʻia i kēlā me kēia cylinder. Ma lalo o ke kūlana calibration, ʻaʻole ʻoi aku ka ʻokoʻa o ka hāʻawi ʻaila o kēlā me kēia cylinder ma mua o 3% ~ 4%. Pono e hoʻololi ʻia ka hoʻolako ʻana i ka wahie me ka hoʻololi ʻana o ke kūlana hana ʻana o ka mīkini diesel, no laila pono ke loaʻa i ka ʻenekini wahie ka mīkini hoʻoponopono.
(2) ʻO ka ʻaila hoʻolako mua Angle o kēlā me kēia cylinder ua like ia, a ʻoi aku ka hewa ma mua o 0.5 ° ~ 1 ° crankshaft Angle. Pono e ho'ololi 'ia ka Angle ho'olako wahie me ke kūlana hana o ka 'enekini diesel, no laila, pono e ho'okomo 'ia ka mea ho'okele wahie.
(3) ʻO ka ʻaila ʻaila Angle o kēlā me kēia cylinder e kūlike.
(4) Hiki iā ia ke hoʻōki koke i ka hāʻawi ʻana i ka aila e pale ai i ka ʻili o ka ʻaila.

Nui nā ʻano o ka pauma wahie, i hoʻohana nui ʻia i nā ʻenekini diesel automotive, e like me ka in-line plunger fuel injection pump and rotor distribution fuel injection pump. Eia kekahi, aia nā pumps - nozzles a pēlā aku.

2. Plunger type wahie injection pump series

No ka mea, ʻokoʻa ākea ka mana o ka pahu pahu hoʻokahi o ka mīkini diesel, inā i hoʻolālā ʻia a hana ʻia ka pauma hoʻoheheʻe wahie e like me ka hāʻawi ʻana i ka aila pōʻai e koi ʻia e kēlā me kēia mana cylinder, ʻo ka nui o nā kikoʻī o ka pauma hoʻoheheʻe wahie e helu ʻia, e hoʻonui ai i ka nui. pilikia i ka hana ʻana a me ka hoʻohana ʻana. No laila, hoʻokumu ʻia nā mea hana pahū injection i ka honua ma luna o kekahi mau puʻupuʻu plunger like ʻole, ua hoʻokaʻawale ʻia ka pauma injection i kekahi mau moʻo a i ʻole nā ​​hiʻohiʻona, a laila me nā ʻāpana like ʻole o ka plunger hui pū ʻana, e hana i kahi helu o nā pauma injection me nā wahie like ʻole. hoʻolako i nā huina e hoʻokō ai i nā pono o nā ʻenekini mana diesel like ʻole. Papa helu 5-4 i kekahi mau pūʻulu o ka pahu pahu pahu pahu pahu i hana ʻia ma Kina a me ko lākou mau palena nui.

A, B moʻo wahie hoʻoheheʻe pauma a i ʻole A, B ʻano wahie hoʻoheheʻe pauma kumu kumu like, ʻo ia ke ʻano kuʻuna o ka plunger wahie injection pump. He ala hou ka P-type fuel injection pump, a hoʻohana i ka pahu-type sealing pump kino me ka wehe ʻole ʻana i ka puka makani ʻaoʻao e hoʻoikaika i ke ʻano o ka pauku wahie. ʻO kēia ka wehewehe ʻana i ke ʻano a me ka loina hana o ke ʻano A a me ke ʻano P wahie injection pump.

3.Working loina o A type wahie injection pump

I ka wā e hoʻololi ai ka pahu pahu o ka pauma hoʻoheheʻe wahie, inā e ʻōwili ka tappet roller ma ka ʻili kumu o ka CAM, kū ka plunger ma ke kūlana o ke kikowaena make lalo o ka plunger. Inā ʻōwili ka ʻōwili i ka ʻāpana hoʻokiʻekiʻe CAM, hoʻokuʻu ka CAM i ke kīpē, a hoʻokuʻu ka tappet i ka plunger i luna, ʻoiai e kaomi ʻia ka pūnāwai plunger. Ke kaʻa ka ʻōwili ma luna o ka piko o ka CAM, hiki ka plunger i ke kikowaena make o luna o ka plunger. A laila, kaʻa ka huila i loko o ka ʻāpana hāʻule CAM, hoʻokuʻu ka pūnāwai plunger i ka plunger, a hoʻokuʻu ka plunger i ka tappet i lalo a hiki i ka ʻōwili ʻana o ka huila i ka ʻili kumu o ka CAM, a hoʻi ka plunger i ka pahu lalo o ka plunger. ʻO ia hoʻi, i ka wā e hana ai ka pauma hoʻoheheʻe wahie, me ka hoʻololi ʻana o ka camshaft, e pānaʻi ka tappet a me ka plunger i loko o ka lua tappet a me ka lima plunger ma waena o ka piko a me lalo o ke kikowaena make o ka plunger.
