Kaum tsib rau nees nkaum xyoo dhau los, qhov teeb meem ntawm kev yuav cov nplhaib rings yog mob heev. Tam sim no qhov ntau ntawm cov khoom seem suav nrog tag nrho cov seem ua kom poob mus rau qhov tsawg tshaj plaws. Txawm li cas los xij, muaj teeb meem hauv kev xaiv cov khoom siv raug hloov kho. Nws yog qhov zoo thiab kev ntseeg tau ntawm piston rings thiab lwm qhov chaw ntawm lub tog raj kheej-piston pawg uas cuam tshuam rau kev pab cuam lub neej ntawm lub cav tom qab kho.
Cov Lus Qhia

Tam sim no, piston nplhaib ntawm ntau qhov ntau thiab tsawg tau tsim rau cov tsheb, txhua tus uas tau suav li 1-2 kho nplhaib. Ib qho ntawm cov ntaub ntawv zoo tshaj plaws yog hlau tshwj xeeb ductile muaj cov khoom coj los tiv thaiv zoo. Tsis yog txhua lub tuam txhab hauv tsev siv cov khoom siv no, yog li them nyiaj rau nws ua ntej.

Roj scraper rings muaj nyob hauv chrome thiab tsis-chrome. Qhov thib peb hom - steel nplhaib nrog lub caij nplooj ntoo caij nplooj ntoos hlav - xaiv tsuas yog rau kev teeb tsa thaum kho lub cav. Lawv tsuas yog ntawm cov nominal loj. Lub nplhaib Chrome yog qhov tsim nyog rau cov tshuab muaj ntau dua cov sib piv thiab muaj ntau cov haujlwm ua haujlwm. Txhawm rau paub qhov txawv ntawm lub nplhaib tsis chrome los ntawm chrome nplhaib, xyuam xim rau cov khoom tiv thaiv. Hauv cov ntawv tsis-chrome plated, lawv yog asymmetrical. Thiab hauv xim, ob qho tib si yog tib yam.

Ua tib zoo saib xyuas lub ntsej muag nthuav dav. Lawv yuav tsum muaj lub suab sib txawv ntawm qhov tig rov qab thiab hauv av ib qho chaw ntawm txoj kab sab nraud thiab sab nraud. Lwm qhov kev xaiv rau cov nplhaib tuaj yeem ua tau cuav, lossis ua rau cov khoom pheej yig thiab muaj peev txheej tsawg. Txheeb xyuas qhov profile thiab qhov siab ntawm cov tabs. Yog tias lawv qhaj lossis tsis tshua pom muaj nyob ze, tom qab ntawd yog cov nplhaib siv siv.

Cov roj pob zeb scraper rings tau dav siv rau hauv lub tsheb txawv teb chaws vim lawv lub neej ntev kev pab cuam, qis dua qhov nyhav thiab nqi siv. Yog tias ua tau (lawv qhov kev siv tsawg), yuav qhov khoom ntawd rau koj lub tsheb hauv tsev.

Thaum xaiv cov nplhaib sib dhos, hnov zoo rau chamfer ntawm ib lossis ob tog ntawm sab nraud ntawm lub nplhaib. Qhov chaw qis-zoo tsis muaj qhov tshwj xeeb. Ib qho ntxiv ntawm cov ntu zoo yog qhov ci ntsa iab thiab ncig. Lub chrome plating ntawm lub nplhaib nyem tsim ib qho kev ua tiav matte. Koj tuaj yeem siv nws kom paub qhov txawv ntawm cov ntiv nplhaib uas tsis yog chrome-plated, uas muaj cov lus ua hlau. Siv lub tshuab hluav taws xob micrometer los kuaj xyuas cov nominal thiab kho qhov loj ntawm lub nplhaib kom paub tseeb tias nws muaj kev nyab xeeb los ntawm kev cuav.

Ua tib zoo saib cov cim rau ntawm cov nplhaib. Lub Hoobkas cim qhia txog qhov loj me thiab tuam txhab raug muab tso rau hauv qhov chaw ruaj khov. Muaj ib txwm muaj qhov sib txawv ntawm qhov chaw tsim ntawm tus cuav. Tsis tas li ntawd, nco ntsoov tias cov nplhaib tau ntim hauv lawv thawj cov khoom ntim hauv hnab ntawv ntawm 3. Lub hnab ntim yuav tsum tau taw qhia: cov khoom siv tus naj npawb, lub cav tsheb thiab lub nplhaib sib txawv. Lub thawv ntawv yuav tsum muaj tus naj npawb ntawm lub tog raj kheej cov khoom siv-hnab ntim sib raug rau cov naj npawb ntawm cov cav ntim lub tog raj kheej rau cov uas lawv tau npaj tseg. Txhua daim ntawv sau yuav tsum siv ib tus ntawv sau, yuav tsum muaj daim npav OTK, lub ntsiab lus gluing ntawm lub thawv yuav tsum yog nyob rau hauv qhov chaw tau hais meej.

Rau kev qhia paub hauv cov khoom vaj khoom tsev ntawm piston rings, siv cov txheej txheem cov txheej txheem rau kev kho thiab seem ntawm lub cav. Nws qhia qhov yuav tsum tau piston lub nplhaib qhov ntev xav tau kev kho tshwj xeeb ntawm lub zog ua haujlwm.

Los txhim kho lub nplhaib luv-lub neej, koj yuav txo lub tog raj kheej hnav thiab ntev lub neej. Tab sis tib lub sijhawm, txhua 30-40 txhiab km yuav tsum tau ua kom tiav lub cav thiab hloov cov nplhaib. Lub nplhaib ntev yuav ntev 150-200 txhiab km. Tom qab kev khiav haujlwm zoo li no, hauv ob qho xwm txheej, koj yuav tsum tau zom cov crankshaft, hloov nws txoj kab thiab ua kev kho me me rau pawg kheej kheej-piston. Xam tawm ntau npaum li cas nws yuav raug nqi los ua disassemble thiab sib sau lub cav txhua 30-40 txhiab.km dhau ntawm 200 txhiab ua kev txiav txim siab thiab txiav txim siab seb qhov kev saib xyuas zoo li cas ntawm lub cav puas tsim nyog rau kev siv nyiaj txiag thiab nqi dag zog.
