Kev tshuaj xyuas yog vim li cas lub injector nozzle daig hauv cov injectors.(part 1)
1 Kev lees paub ntawm cov khoom kuaj
Los ntawm kev tshuaj xyuas ntawm cov laj thawj uas tuaj yeem ua rau kev sib txuas ntawm lub nozzle koob valve, nws tau txiav txim siab los ua cov kev tshuaj xyuas thiab tshuaj xyuas ntawm qhov tsis ua haujlwm nozzle sib dhos.Cov khoom soj ntsuam tshwj xeeb yog raws li hauv qab no:
1) Txheeb xyuas qhov sib txawv ntawm qhov sib txuas thiab qhov haum ntawm rab koob valve lub rooj zaum saum npoo;
2) Rov ntsuas lub roundness, cylindricity, roughness, thiab deg hardness ntawm rab koob valve tom qab ntxuav (tshem nto xeb, thiab lwm yam);
3) Kev ntxuav (tshem tawm xeb xeb, thiab lwm yam)
4) Tshem tawm lub koob valve thiab lub nozzle, thiab ua cov xim tshuaj ntsuam xyuas ntawm lub mating nto ntawm rab koob valve thiab nozzle;
5) Xa lub koob valve thiab nozzle rau metallographic tshuaj xyuas, ntsuas impurity piv.
2 xeem
2.1 Cov txiaj ntsig kev ntsuas ntawm lub taub sab nraud ntawm rab koob valve haum qhov chaw thiab lub puab txoj kab uas hla ntawm lub nozzle fitting nto yog qhia nyob rau hauv Table 1. Ntawm lawv, txawm qhov chaw nrog stamp tooj HHM tsis ntsia thiab khiav.Los ntawm cov ntaub ntawv ntsuas, nws tuaj yeem pom tias qhov sib txawv ntawm ob qhov sib txuas yog ntau dua li tus nqi tsim, qhov sib npaug ntawm lub qhov hauv lub qhov ntawm lub koob valve thiab lub nozzle nrog lub stamp tooj HD tag nrho ua tau raws li cov qauv tsim, thiab lub roundness ntawm lub puab qhov ntawm lub koob valve thiab lub nozzle nrog lub stamp tooj HHM tshaj qhov tsim yuav tsum tau.Qhov chaw ntawm lub koob valve nrog steel stamp tooj HD yog qhov hnyav heev, thiab qhov chaw haum tsis tuaj yeem kuaj xyuas.Qhov xwm txheej tshwj xeeb yog qhia hauv daim duab 2.
Qhov haum ntawm lub koob valve nrog steel stamp tooj HHM yog dav dua, nrog lub bandwidth ntawm li 2 hli, raws li qhia hauv daim duab 3 (qhov mating nto yuav tsaus dua tom qab khub yog me ntsis hauv av, yog li koj tuaj yeem tshawb xyuas qhov haum).Tsis tas li ntawd, lub khob hliav qab lub kaum sab xis ntawm qhov kawg ntawm lub koob valve yog ntsuas, thiab tus tsim yuav tsum muaj lub khob hliav qab ntawm 91 ° ± 5 '.Lub kaum sab xis ntawm cov hlau foob tus lej pib HHM yog 91 ° 1', thiab rab koob lub kaum sab xis ntawm cov hlau stamp tooj pib HD yog 91 ° 2', ob qho tib si ua tau raws li qhov yuav tsum tau ua ntawm cov duab kos.
