Yog tias lub tsheb qhov kev ua haujlwm tsis zoo tau poob qis, kev siv roj thiab roj tau nce ntxiv, teeb meem pib tshwm sim, qhov no qhia tias lub cav hnav. Tab sis qhov no tseem tsis tau txiav txim siab. Cov tsos mob no qhia tau hais tias cov nplhaib yuav tsum tau hloov. Cia peb saib yuav ua li cas muab cov nplhaib ntawm lub piston. Cov txheej txheem tsis yooj yim, tab sis yuav tsum muaj cov cuab yeej thiab kev saib xyuas.

Koj yuav tsum hloov dab tsi?

Rau cov txheej txheem zoo li no, nws tsim nyog npaj ib txheej wrenches, ratchet nrog lub qhov (socket heads), lub torque wrench, lub nplhaib piston tshem tawm thiab lub nplhaib teeb tsa nws tus kheej.

Lub Piston Ring Mounting / Dismounting Tool nta cov qauv yooj yim thiab tus nqi tsim nyog. Yog tsis muaj cov cuab yeej no, cov txheej txheem hloov pauv tuaj yeem hloov mus ua haujlwm yuav luag tsis tuaj yeem. Tau kawg, ua ntej cov neeg tsav tsheb tau tswj nrog ob peb lub hau ntswj. Tab sis nws yog qhov zoo dua tias muaj cov cuab yeej zoo li no, txwv tsis pub, tsis muaj nws, koj tuaj yeem ua kom puas lub nplhaib lossis qhov chawpiston. Ntxiv mus, nws yeej ib txwm muaj nyob rau hauv lub lag luam tsheb.

Txoj kev xaiv cov nplhaib

Yuav kom lub cav ua haujlwm ruaj khov tom qab kho, nws yog ib qho tseem ceeb uas yuav tau xaiv lub nplhaib zoo. Tsis txhob yuav cov khoom pheej yig tshaj plaws. Cov nplhaib zoo li no yuav tsis kav ntev, thiab koj yuav tau mus dhau cov txheej txheem ua haujlwm ntawm kev hloov dua tshiab.

Nws tseem ceeb heev rau kev tshuaj xyuas cov ntim thiab cov khoom lawv tus kheej. Lub ntim yuav tsum muaj tag nrho cov ntaub ntawv hais txog cov chaw tsim khoom, cov khoom ntawm kev tsim khoom. Rings yuav tsum tau cim. Nws sawv cev rau sab saum toj. Cov neeg tsim khoom feem ntau muab cov lus qhia rau hauv lub pob, uas qhia meej yuav ua li cas muab cov nplhaib rau ntawm lub piston kom zoo. Cov tom kawg yuav tsum tsis muaj qhov tsis xws luag, txawm tias qhov tsawg tshaj plaws.

Yuav hloov lub nplhaib li cas?

Los ntawm cov lus qhia no koj tuaj yeem kawm paub yuav ua li cas muab lub nplhaib ntawm lub piston ntawm VAZ thiab lwm lub tsheb, suav nrog cov tsheb txawv teb chaws. Yuav hloov, dismantle lub lauj kaub roj. Tom qab ntawd cov hlua txuas txuas yog unscrewed, cov hlua txuas txuas tau raug thawb tawm. Tshem cov nplhaib nrog lub cuab yeej tshwj xeeb.

Nws yog ib qho tseem ceeb kom tshem tawm cov pa roj carbon deposits ntawm cov grooves - koj yuav tsum tau ntxuav lawv mus rau cov hlau. Cov dej tsis huv yuav cuam tshuam nrog kev txhim kho cov nplhaib tshiab hauv cov rooj zaum. Nws yog qhov yooj yim los ntxuav lub piston nrog ib feem ntawm qhov qub. Txhawm rau kom ceev cov txheej txheem tshem tawm cov pa roj carbon deposits, koj tuaj yeem tsau lub piston hauv dimexide lossis lwm yam dej ntxuav.

Tam sim no peb yuav tsum xav txog yuav ua li cas muab cov nplhaib ntawm lub piston. Qhov no yuav tsum tau saib xyuas thiab raug. Cov rings yog qhov yooj yim heev, thiab qhov tsis yooj yim tshaj ntawm lawv yog qhov nruab nrab. Thaum lub sij hawm lub installation txheej txheem, ib feem yog heev yooj yim mus tawg. Thaum txhim khoNws yog ib qho tseem ceeb uas yuav tsum tau taw qhia lub nplhaib kom raug, txwv tsis pub yuav tsis muaj txiaj ntsig zoo los ntawm kev hloov pauv, thiab txawm tias rov qab - tus neeg tsav tsheb yuav ntsib kev noj roj ntau dua.

Ua ntej ntawm tag nrho, nruab lub nplhaib sab saum toj. Lawv tau sau tias "TOP". Nrog rau qhov cim no, lub caij yuav tsum fim lub piston crown. Qhov seem yog ntsia nrog lub scraper cia. Chamfered rings yog mounted kom lawv saib upwards.

Yog hais tias qhov chaw yog hom-setting, roj scraper nrog ob-functional caij nplooj ntoos hlav expander, ces lub sab sauv thiab nruab nrab sawv daws yuav ntsia ua ntej.

Muaj lwm qhov kev txiav txim rau kev txhim kho cov nplhaib ntawm lub piston. Nyob rau hauv rooj plaub no, cov roj scraper yog ntsia ua ntej. Thawj mount qhov thib ob, ces thawj. Tom qab ntawd, ib tug compression yog ntsia. Lub nplhaib compression thib ob thiab cov roj scraper yuav tsum tau ua tib zoo ntsia. Lawv yooj yim heev thiab tsis zam kev nthuav dav.

Tom qab ntawd nws yog ib qho tseem ceeb ua raws li cov xauv ntawm lub nplhaib. Lawv yuav tsum nyob ntawm kaum ntawm 120 degrees rau ib leeg. Yog hais tias lawv converge, yuav muaj roj noj thiab haus luam yeeb los ntawm lub crankcase ventilation system.

Kev hloov ntawm maus taus

Ntawm scooters thiab mopeds, qhov no yog ib qho txheej txheem uas tau ua ib zaug lossis ob zaug hauv ib lub caij. Rings nyob rau hauv xws li engine yog consumables. Txawm hais tias lub cav yog Japanese, cov ntsiab lus ntawm pawg piston hauv nws yog Taiwanese zoo tshaj plaws, thiab feem ntau yog Suav.

Nyob rau hauv Nyiv, tom qab kev tawg, nws yog ib txwm ua kom tshem tawm cov khoom siv - nws yog pheej yig dua thiab yooj yim dua los yuav lub scooter tshiab. Nyob ntawd, qhov kev puas tsuaj loj yog suav tias yog qhov poob hauv compression vim hnav ntawm cov nplhaib.thiab pistons. Qhov tseeb, kev kho yog los hloov qhov chaw ntawm pawg piston. Wb saib yuav ua li cas muab rings rau ntawm lub scooter piston.

Plaub-stroke scooter xyaw

Yog li ntawd, muaj ib lub nplhaib, thiab tus tswv tsis paub yuav ua li cas rau lawv. Muaj tsib lub nplhaib hauv lub teeb - ob lub nyias nyias, ib qho roj scraper, thiab ob lub nplhaib compression. Muaj peb grooves ntawm lub scooter piston.

Muaj lubricated lub piston nrog roj, ua tib zoo muab lub nplhaib nyias rau hauv qhov zawj qis. Lawv muab cov roj scraper rau nws. Ces nyias dua. Peb lub nplhaib yuav tsum tau muab tso rau hauv ib lub groove. Cov roj scraper yuav tsum nyob nruab nrab ntawm ob lub nyias nyias.

Tom qab ntawd, cov nplhaib compression tau muab tso rau. Lawv yuav tsum tau muab ntsia rau saum grooves. Nws tsis pom zoo kom siv cov cuab yeej thib peb rau kev teeb tsa. Nws yuav tsum nco ntsoov tias cov rings yog qhov yooj yim heev thiab tawg yooj yim. Yog hais tias qhov compression qhov sib txawv, ces ib qho yog feem ntau sib npaug, thiab qhov thib ob yog nyob rau hauv cov duab ntawm ib tug trapezoid. Qhov sib npaug yog muab tso rau hauv qhov zawj sab saud, thiab lub trapezoidal yog qis dua. Lub bevel yuav tsum nthuav los ntawm sab saum toj mus rau hauv qab. Lub nplhaib yuav tsum dav nyob rau hauv qab ntawm qhov zawj tshaj qhov saum toj.

Xaiv tsis tau muab tso rau saum ib leeg. Lawv yuav tsum nyob ntawm kaum ntawm 120 degrees rau ib leeg. Ntawm no yog yuav ua li cas muab rings rau moped piston. Raws li koj tau pom, tsis muaj dab tsi nyuab ntawm no.

Mopeds “Alfa”

Cov txheej txheem no nrov heev hauv tebchaws Russia. Thaum twg yuav tsum tau hloov lub nplhaib thiab pistons? Qhov kev ua haujlwm no yog nqa tawm nrog kev txo qis hauv compression mus rau 450 kPa. Nws kuj tauntsuas nrog compression gauge. Tsis tas li ntawd, kev tso tawm yuav qhia txog qhov yuav tsum tau hloov pauv: yog tias muaj cov pa luam yeeb hauv cov pa, ces cov nplhaib yuav tsum tau hloov. Lawv raug hloov ntawm cov mopeds txhua 10-12 txhiab kilometers.

Ua ntej mounting cov khoom, koj yuav tsum manually haum lawv mus rau hauv lub zawj nyob rau hauv lub piston. Lawv yog sawn nrog ib rab koob ntaub ntawv thiab kho nrog sandpaper. Tom qab ntawd nws yog ib qho tsim nyog ntsuas qhov sib txawv ntawm lub xauv ntawm lub nplhaib, uas yog ntxig rau hauv lub tog raj kheej yam tsis muaj kev cuam tshuam. Qhov chaw ib txwm rau qhov tshiab compression yog 0.04-0.08 hli. Qhov zoo tshaj plaws clearance rau roj scrapers yog 0.025–0.065 mm.

Yog tias qhov chaw compression raug hloov, ces lawv hloov mus rau cov uas tsis yog chrome. Cov kws tshaj lij qhia koj yuav ua li cas muab cov nplhaib ntawm Alpha piston: lub nplhaib kom haum rau lub piston zaum hauv qhov zawj hauv qab nws qhov hnyav. Yog tsis mus ces nias rau me ntsis xwb.

Nyob hauv kaw

Hloov cov nplhaib yuav pab kho lub cav compression thiab qee zaum txo cov roj noj. Tab sis nws yeej tsis pab. Yog hais tias lub tog raj kheej hnav tawm thiab muaj lub ntsej muag ellipse, ces cov khoom tshiab yuav siv sij hawm ntev los rub tawm ntawm lub tog raj kheej. Qhov no yuav ua nrog roj noj, xiav tso pa tawm, pa taws los ntawm crankcase qhov cua tshuab. Tab sis yog tias tseem muaj lub Hoobkas hone ntawm lub tog raj kheej, thiab kev ntsuas qhia tias hnav me me, ces koj tuaj yeem kho lub piston kom ruaj ntseg. Yuav ua li cas muab rings rau ntawm lub piston, peb tshuaj xyuas hauv kab lus.
