Cov Ua Rau Feem Ntau Thiab Cov Lus Qhia Txog Kev Kho Mob Rau Kev Hloov Pauv Ntawm Lub Bonnet Structural Assembly

Cov qauv ntawm lub bonnet tsis yog teeb meem ntau hauv cov li qub me me, tab sis thaum nws siab dua DN400, qhov yuam kev sib dhos yooj yim raug nthuav tawm. Ntau lub pob li qub lossis lub qhov rooj li qub ntawm qhov chaw ua haujlwm muaj qhov qhib thiab kaw tsis zoo lossis ntim tsis ua haujlwm, thiab lawv txhua tus cuam tshuam nrog qhov tsis sib xws lossis kev hloov pauv ntawm lub hau li qub.

Peb tau ua ib qhov project loj rau cov chaw khawb av, thiab tus neeg siv khoom hais tias lub suab qhib thiab kaw tsis raug, thiab lub pob valve tes tau daig ib nrab. Thaum xub thawj, lawv xav tias nws yog teeb meem nrog lub valve stem lossis pob, tab sis tom qab peb rov qab mus rau lub Hoobkas kom xyuas seb nws puas yog qhov ntaus me ntsis ntawm qhov flange ntawm sab ntawm lub hau valve, uas ua rau lub qhov rooj qis dua ntawm lub cev valve tawm ntawm qhov chaw nruab nrab ntawm lub cev valve los ntawm 0.3 hli. Nws zoo li tsis loj, tab sis thaum lub pob core tig, lub axis tsis sib xws thiab lub torque tsis ruaj khov.

Txhawm rau teb rau hom teeb meem no, tam sim no peb muab cov lus qhia rau cov neeg siv khoom: daim duab kos yuav tsum tau cim meej nrog qhov chaw teeb tsa, thiab feem ntau nws raug pom zoo kom siv qhov chaw flange sab saud lossis qhov chaw nruab nrab ua qhov siv los ua clamping. Tshwj xeeb tshaj yog rau cov kab uas hla loj, peb pom zoo kom siv kev ua haujlwm tig ntsug, uas tsis muab faib ua ob txoj haujlwm. Yog tias sab ntawm tus neeg siv khoom tsis tuaj yeem clamped tag nrho, peb tuaj yeem pab ntxiv cov grooves lossis cov kab qhia raws li cov txheej txheem kos duab.

Ntxiv mus, thaum lub sijhawm sib dhos ntawm qee qhov project, qhov kev hloov pauv ntawm lub qhov ntsia hlau ntawm lub hau valve ua rau muaj kev sib dhos yuam, uas zoo li tsis muaj teeb meem rau kev teeb tsa, tab sis qhov tseeb, qhov kev ntxhov siab preload tsis sib xws, thiab nws yooj yim kom xoob lossis xau tom qab lub sijhawm ua haujlwm. Peb feem ntau ua qhov kev lees paub sib dhos ua ntej xa khoom, thiab qhov loj me tseem ceeb yog txhua qhov ntsuas kom ntseeg tau tias qhov khiav tawm ntawm lub nplhaib flange yog nyob rau hauv 0.05, thiab qhov ntsug ntawm lub qhov thiab axis yog raws li tus qauv.

Txawm hais tias lub hau yog ib qho khoom haum, nws yog 'qhov pib' ntawm qhov tseeb ntawm tag nrho cov qauv sab saud, thiab yog tias nws tsis raug, lub pob core, lub valve stem, thiab lub thawv stuffing yuav raug cuam tshuam. Nws raug pom zoo kom tus neeg siv khoom xav txog qhov kev sib raug zoo ntawm theem tsim, thiab yog tias tsim nyog, peb kuj tuaj yeem muab cov lus qhia txog kev sib dhos lossis pab kho qhov kev xav ntawm tus qauv kom tsis txhob rov ua haujlwm dua.
