Txhaj Nozzle DLLA158P1096 rau Common Rail Injector 093400-1096

Txoj kev dismantling ntawm lub injector nozzle khub (Part 3)

Yog hais tias lub valve kab ntawm rab koob valve thiab lub cev injector tsis sib npaug, nws tuaj yeem raug yuam kom koom tes los ntawm kev khob thiab stamping. Muab lub koob valve dipped nyob rau hauv ib co roj rau hauv lub roj injector lub cev, muab ib tug plunger nti rau ntawm lub koob valve kov, thiab maj mam ntaus ib tug kaum os rauj nrog ib tug ib nrab-phaus rauj los tiv thaiv lub koob valve thiab lub roj injector lub cev los ntawm lub khob hnyav. . Yog tias cov hlau puas lawm, tig nws 90 ° thiab khob dua, thiab tig nws peb zaug hauv tag nrho kom ua tiav qhov zoo.

Muaj cov cim qhia ntawm kev puas tsuaj rau lub cev injector valve hlau thiab koob valve hlau. Yog tias cov cim kev puas tsuaj loj, siv me me ntawm coarse abrasive muab tshuaj txhuam rau hauv kab valve ntawm rab koob lub taub hau, thiab clamp lub koob valve kov rau cov cuab yeej tshwj xeeb disassembly rau kev cuam tshuam thiab kev sib tsoo. Yog hais tias koj muaj lub rooj ntev zaum xyaum los yog ib tug xyaum tes, koj muaj peev xwm nruab ib rab koob valve kov ntawm lub chuck thiab tig nws rau kev sib tsoo, tab sis qhov ceev yuav tsum tsis txhob ceev heev, thiaj li yuav tiv thaiv tau lub valve kab los ntawm kev nyuaj rau restore smoothness. kom ceev sib tsoo.

Thaum sib tsoo, koj yuav tsum pinch lub injector lub cev nrog koj txhais tes thiab tsis tu ncua cuam tshuam thiab tig rau hauv axial kev taw qhia. Sib tsoo rau 2 ~ 3 feeb kom pom qhov sib koom ua ke ntawm rab koob valve taper valve kab. Tab sis kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias cov abrasive muab tshuaj txhuam yuav tsum tsis txhob siv los yog kov ntawm lub cylindrical qhia saum npoo ntawm rab koob valve kom tiv thaiv kev puas tsuaj los ntawm kev puas tsuaj ntawm lub cylindrical daim ntawv qhia nto ntawm rab koob valve. Sib tsoo cov kab ntawm kev puas tsuaj, siv lub koob txhaj tshuaj los nqus cov roj diesel huv, thiab yaug cov tshuaj txhuam hniav tawm tsam lub cev lub cev. Tom qab ntawd siv chromium oxide los zom lub cev txhaj tshuaj tib yam li qhia hauv daim duab 6, thiab tom qab ntawd zom nws nrog cov roj cav rau 1 ~ 2min, kom cov kab valve ntawm rab koob valve taper ncav cuag ib puag ncig smoothness. Qhov dav ntawm qhov sib koom ua ke ntawm lub valve hlau yog feem ntau txog 0.1 hli.
