  Yuav ua li cas disassemble, ntxuav lossis kho lub tshuab nqa hydraulic

  Yuav tsim dab tsi - sau cov roj uas tsim nyog, uas muaj peev xwm tswj tau nws cov yam ntxwv txawm nyob rau qhov tseem ceeb frosty kub.

• Tsis tuav lub hydraulic compensator valve, thaum roj ntws rov qab los ntawm lub valve, thiab HA tau tshaj tawm. Thaum lub sij hawm kaw, lub combustion engine txias cia, tom qab uas lub lubricant kuj hloov nws lub cev zog. Yog li ntawd, kom txog rau thaum lub internal combustion engine warms li, roj yuav tsis pib ntws mus rau hauv lub system. Yuav tsim dab tsi - hloov lub valve los yog hydraulic compensator.
• Clogged roj lim. Txhua yam yog yooj yim thiab pom tseeb ntawm no.Yuav tsim dab tsi - hloov lub lim.

Yuav ua li cas cov roj mus ncuav yog hydraulic lifters khob

Ua ntej xaiv cov roj, koj yuav tsum txiav txim siab raws nraim thaum lub hydraulics khob. Feem ntau lub khob tau hnov ​​​​dhau tam sim ntawd tom qab pib, yog li koj yuav tsum tsim kom muaj cov roj twg los sau rau hauv yog tias cov hydraulic lifters khob ntawm txias. Qhov no yog ib qho teeb meem tshwm sim, tshwj xeeb tshaj yog rau cov tswv ntawm VAZ 2110, Priora thiab Kalina.

Ua raws li txoj cai - yog tias cov hydraulics khob qhov txias, ces koj yuav tsum tau sau cov roj ntau dua. Piv txwv li, yog tias koj lub tsheb tau ntim nrog 10W40 roj, tom qab ntawd txhawm rau tshem tawm lub khob, koj yuav tsum hloov mus rau 5W40. Koj tuaj yeem sim sau rau hauv hom 5W30.

Rau cov neeg uas tsis paub yuav ua li cas cov roj sau nyob rau hauv yog hais tias lub hydraulic lifters yog khob kub, ces koj tuaj yeem sim sau cov additive. Qhov no feem ntau ua yog tias lub khob los ntawm hydraulics tau hnov ​​​​txhua lub sijhawm. Hauv 80% ntawm txhua kis, kev siv tsuas yog ib qho Liqui Moly Hydro-Stossel-Additiv additive tuaj yeem daws qhov teeb meem.

Tab sis yog tias qhov no tsis pab, koj yuav tsum hloov cov roj nrog cov kua ntau dua, xaiv lwm lub chaw tsim khoom. Nws yog ib qho tseem ceeb los xaiv qhov zoo tshaj plaws viscosity (qhov no feem ntau yog 5W40). Yog tias cov roj nyias dhau los siv rau hauv lub tshuab hluav taws xob sab hauv, lub siab hauv lub cev yuav poob thiab cov hydraulic lifters yuav tsis puv nrog roj.

Yog lawv khob tshiab hydraulic lifters, ces nws yog qhov yooj yim dua los txiav txim siab seb cov roj yuav nchuav. koj yuav tsum tau sau cov roj semi-synthetic tshiab. Piv txwv li, yog tias koj muaj 5W40 hluavtaws roj ntawm Priora, ces koj tuaj yeem xaiv tib viscosity, tab sis semi-synthetics.

Tsis txhob txhawj yog tias hydraulic lifters khob ntawm idle. Thaum pib lub cav combustion sab hauv, qhov tshwm sim no feem ntau yog ib ntus, thiab qhov no yog vim lub viscosity ntawm cov roj. Thaum cov roj warms mus rau qhov kub thiab txias, lub khob yuav ploj mus. Yog tias lub khob hnov ​​​​thaum lub sijhawm tsis ua haujlwm, qhov no qhia tau tias yuav tsum tau hloov cov roj mus rau cov kua ntau dua.

Thaum tas li knocking hydraulic lifters, ces nws yog qhov zoo dua tsis txhob siv cov khoom siv ntxiv lossis daws qhov teeb meem los ntawm kev hloov cov roj - koj yuav tsum tau xyuas cov hydraulic lifters, vim hais tias feem ntau lub khob tsis tu ncua qhia tias tsis ua hauj lwm ntawm ob peb hydraulics ib zaug los yog muaj ntau cov resinous deposits nyob rau hauv lub cev muaj zog. thiab nyob rau hauv thiaj li yuav tau txais cov lubrication kom zoo, koj yuav tsum tau yaug lub roj system.

Yog vim li cas tshiab hydraulic lifters khob

Cov roj av qias neeg

Tapping tshiab hydraulic lifters thawj zaug yog qhov qub. Tab sis yog tias lub khob tsis ploj sai sai, ces koj yuav tsum nrhiav qhov teeb meem. Xav tias xws li hydraulic lifters tsis muab rau hnav, nws tsis zoo li yog vim li cas. Tab sis nws yog ntshaw tias thaum yuav ib tug tshiab set ntawm compensators, koj yuav tau txais ib tug guarantee. Yog li koj txuag nyiaj nyob rau hauv rooj plaub ntawm kev sib yuav los yog ib qho tsis tsim nyog version ntawm cov neeg them nyiaj tau hais.

Kev teeb tsa tsis raug, thiab vim li ntawd, tsis muaj cov roj nplua nyeem, uas yog vim li cas hydraulic lifters khob. Lwm yam teeb meem tshwm sim kuj tau txiav txim los ntawm qhov tseeb tias compensators tsis pumped - roj tsis ncav cuag lawv. Clogged oil channels, faulty oil pumps, thiab cov zoo li yuav ua txhaum ntawm qhov no.
