Overhaul Method ntawm Camshaft ntawm Cummins Generator Teeb

Feem ntau qhov ua txhaum ntawm lub camshaft ntawm Cummins diesel generator teeb muaj xws li hnav tsis xws luag, suab nrov txawv txav thiab tawg.Cov tsos mob ntawm kev coj txawv txawv feem ntau tshwm sim ua ntej qhov tshwm sim ntawm lub suab txawv txav thiab pob txha.

1. Lub camshaft ntawm diesel generator teeb yog yuav luag kawg ntawm lub cav lubrication system, yog li cov txheej txheem lubrication tsis zoo.Yog hais tias cov roj twj tso kua mis muaj cov roj txaus siab vim lub sij hawm siv ntau dhau los yog lwm yam laj thawj, los yog cov roj lubricating tau raug thaiv thiab cov roj lubricating tsis tuaj yeem ncav cuag lub camshaft ntawm lub tshuab hluav taws xob diesel, los yog lub zog nruj ntawm cov kabmob cap fastening bolts. loj heev, cov roj lubricating tsis tuaj yeem nkag mus rau hauv lub tshuab hluav taws xob diesel teeb Camshaft tshem tawm yuav ua rau muaj qhov txawv txav ntawm lub camshaft ntawm lub tshuab hluav taws xob diesel.

2. Qhov txawv txav ntawm lub camshaft ntawm lub tshuab hluav taws xob diesel teeb yuav ua rau qhov sib txawv ntawm lub camshaft thiab lub rooj zaum bearing nce, thiab lub camshaft ntawm lub tshuab hluav taws xob diesel yuav txav axially, ua rau lub suab nrov txawv txav.Kev coj txawv txawv kuj tseem yuav ua rau qhov sib txawv ntawm lub cam tsav thiab hydraulic tappet nce.Thaum lub cam ua ke nrog hydraulic tappet, ib qho kev cuam tshuam yuav tshwm sim, uas yuav ua rau lub suab nrov txawv txav.

3. Diesel generator teeb camshafts qee zaum muaj teeb meem loj xws li pob txha.Feem ntau ua rau muaj xws li hydraulic tappet cracking los yog hnyav hnyav, lubrication hnyav, tsis zoo ntawm diesel generator teeb camshafts, thiab tawg diesel generator teeb camshaft sij hawm zog, thiab lwm yam.

4. Qee qhov xwm txheej, qhov ua haujlwm tsis zoo ntawm lub camshaft ntawm lub tshuab hluav taws xob diesel teeb yog tshwm sim los ntawm cov neeg tsim vim li cas, tshwj xeeb tshaj yog thaum lub camshaft ntawm lub tshuab hluav taws xob diesel tsis zoo disassembled thiab sib sau ua ke thaum lub cav kho.Piv txwv li, thaum disassembled lub camshaft bearing cap ntawm lub diesel generator teeb, siv ib tug rauj los yog ib tug ntswj ntsia hlau, los yog nruab lub bearing cap nyob rau hauv tsis ncaj ncees lawm txoj hauj lwm, ua rau tsis sib haum xeeb ntawm lub bearing cap thiab lub rooj zaum bearing, los yog nruj nreem kaw. torque ntawm fastening bolts ntawm bearing cap yog loj heev, thiab lwm yam.Thaum txhim kho cov kabmob npog, ua tib zoo saib rau qhov taw qhia xub thiab tus lej ntawm qhov chaw ntawm cov kabmob npog, thiab siv lub torque ciaj ntswj txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nruj.

Kev xav tau - camshaft

1) Lub camshaft yuav tsum tsis txhob khoov lossis tawg;cov ntaub ntawv yuav tsum tsis txhob muab stripped, crushed, los yog strained.Kev hnav ntau dhau yuav tsum tau kho;cov xov ntawm lub ncej kawg yuav tsum zoo.

2) Tso cai rau kev hloov kho txias thiab ncaj.

3) Lub cam ua hauj lwm nto yuav tsum tsis muaj tev, pits lossis puas;Thaum lub cam profile hnav ntau dua 0.15mm, nws raug tso cai rau kev sib tsoo, thiab qhov tawv tawv tom qab sib tsoo yuav tsum tsis txhob qis dua HRC57.Lub tshuab nqa crankshaft yuav tsum ua tau raws li tus qauv tsim qauv, tab sis nrog Lub voj voog lub voj voog ntawm lub tshuab cua yuav tsum tsis pub tsawg dua 49.5mm, thiab lub voj voog puag ncig ntawm cov roj cam yuav tsum tsis pub tsawg dua 47.0mm.

Iav kis tau tus mob

1. Tom qab kev tshuaj xyuas, tag nrho cov iav tsis raug tso cai kom muaj kev tawg, tawg, thiab hnav ib nrab.Qhov chaw ntawm qhov chaw ntawm cov hniav yuav tsum tsis pub tshaj 10% ntawm qhov chaw ntawm cov hniav, thiab qhov kev puas tsuaj nyuaj yuav tsum tsis pub tshaj 5% ntawm qhov chaw ntawm cov hniav.

2. Cov hlua khi yuav tsum tsis txhob tawg lossis puas.Lub verticality ntawm lub axis ntawm lub bracket ncej mus rau lub bracket mounting flange yuav tsum tau raws li qhov tsim nyog.

3. Qhov sib koom ua ke ntawm lub bracket thiab lub cev yuav tsum tau ua tib zoo txuas.Tom qab cov ntsia hlau tau nruj, 0.03mm qhov ntsuas qhov ntsuas tsis raug tso cai.

4. Tom qab lub iav tau sib sau ua ke, nws yuav tsum tig tau yooj yim, cov cim tau meej thiab tiav, thiab cov roj lubricating txoj kev yog huv si thiab tsis muaj kev cuam tshuam.

4. Ib ntu camshafts raug tso cai hloov.

5. Lub radial runout ntawm txhua phau ntawv journal ntawm lub camshaft mus rau cov axis ntawm cov phau ntawv journal 1, 5, thiab 9 yog 0.1 hli, thiab indexing kam rau ua ntawm txhua lub cam txheeb ze rau lub cam ntawm tib lub npe ntawm thawj ( cuaj) txoj hauj lwm yog 0.5 degrees.

Kho txoj kev

1. Kev kho deg: Siv cov pa acetylene los ci rau saum npoo ntawm cov khoom hnav ntawm lub cav camshaft kom txog thaum tsis muaj qhov tawg, thiab tom qab ntawd txhawb nqa cov khoom hnav, thiab tom qab ntawd txhuam qhov hnav ntawm lub camshaft ntawm tsim teeb kom nthuav tawm cov xim hlau qub, thiab tom qab ntawd ntxuav thiab txhuam cov khoom hnav nrog ethanol kiag li;

2. Tom qab kev sim khoob ntawm cov kabmob, ntxuav cov kabmob sab hauv ntawm cov kabmob nrog cov ethanol kiag li thiab siv Soleil SD7000 tso tawm tus neeg sawv cev tom qab qhov kev sim khoob yog lawm;

3. Sib xyaw ua ke ntawm Soleil carbon nano-polymer cov ntaub ntawv, muab sib xyaw kom zoo ib yam thiab tsis muaj xim sib txawv, thiab tom qab ntawd muab cov khoom sib xyaw ua ke rau cov khoom yuav tsum tau kho;

4. Txhim kho cov kabmob thiab ua kom sov cov khoom kom ruaj khov;

5. Tshem tawm cov kabmob, tshem tawm cov khoom siv ntau dhau ntawm qhov chaw, thiab siv cov khoom siv ob zaug;

6. Txhim kho lub cam thiab xyuas kom meej qhov chaw thiab kev taw qhia ntawm lub cam kom ntseeg tau tias kev siv cov nyhuv tom qab kho, ces kev kho yuav ua tiav.

Pump kis tau tus mob

1. Ntxuav tag nrho thiab tshem tawm cov roj stain hauv cov roj hluav taws xob.

2. Lub thawv txhawb nqa lub twj tso kua mis yuav tsum tsis muaj kab nrib pleb thiab kev puas tsuaj, thiab kev sib cuag ntawm qhov chaw yuav tsum tiaj tus.
