Zoo Zoo Tshiab Diesel Injector Nozzle L381PBD Common Rail Injector Nozzle rau Diesel Injector Spare Parts

Kev tshuaj xyuas yog vim li cas lub injector nozzle daig hauv cov injectors. (part 4)

Cov khoom xeem uas tsis tau raws li qhov yuav tsum tau ua hauv cov ntaub ntawv yog: 1) Qhov sib txuam ntawm ob lub steel stamp tooj yog ntau dua tus nqi tsim;

2) Qhov hardness thiab roughness ntawm lub nozzle sab hauv qhov ntawm ob lub hlau stamp tooj tsis ua raws li qhov yuav tsum tau ua. Qhov tawv tawv ntawm No. HHM yog qis dua tus nqi tsim;

3) Lub roundness ntawm rab koob valve thiab nozzle ntawm cov hlau stamp No. HHM tshaj qhov tsim nyog;

4) Cov ntsiab lus C thiab V ntawm cov khoom siv ntawm lub koob valve ntawm ob lub thwj steel yog qis dua li lub teb chaws tus qauv yuav tsum tau, thiab thawj lub cim steel tsis yog HD nozzle C cov ntsiab lus ntawm 0.20% yog me ntsis siab dua li cov qauv hauv lub tebchaws.

5 Kev xaus Nws tuaj yeem pom los ntawm daim duab ntawm lub koob valve (Daim duab 2) tias cov pa roj carbon tuab tau tsim nyob rau saum npoo ntawm rab koob valve, yog li nws tuaj yeem txiav txim siab tias qhov sib txuam ntawm cov koob valve khub tsis kam lees , thiab inclination ntawm rab koob valve nyob rau hauv lub nozzle ntau tshaj Vim hais tias ntawm tus tsim ntau yam, lub conical nto nyob rau hauv pem hauv ntej kawg ntawm lub koob valve yuav tsum reliably kaw. kub kub
Cov roj hluav taws xob siab mus rau retrogradely los ntawm lub nozzle orifice mus rau cov roj kab noj hniav ntawm kev sib txuas los tsim cov pa roj carbon deposits, uas yuav ua rau cov coupling los lo thaum cov pa roj carbon deposits nce. Tsis tas li ntawd, qhov nyuaj ntawm qhov chaw thiab qhov roughness ntawm lub puab qhov ntawm lub nozzle tsis tau raws li qhov tsim nyog yuav tsum tau, yog li ntawd lub koob valve los ua ke yuav muaj feem cuam tshuam los ntawm carbon deposits thiab ua rau stagnation.
