Many car owners are very careful when buying auto parts, but it is easy to forget the maintenance of parts after installation. In this way, with the gradual increase of car travel, the parts are very easy to wear and the service time is continuously shortened. Let's learn about the complete collection of maintenance methods of auto parts!
1. Auto qhov chaw ntshai tsam qias neeg
If the fuel filter, oil filter, air filter, hydraulic oil filter, various filters and other components are too dirty, the filtering effect will become worse, and too many foreign matters will enter the oil circuit cylinder, resulting in component wear and higher possibility of failure. If there is a serious traffic jam, the vehicle may not work properly. If the radiator fins, air-cooled engine block and head fins, cooler fins and other components are too dirty, the heat dissipation will become worse and the temperature will be too high. Therefore, clean and maintain such "dirty" parts immediately.
2. Thaum tshav kub kub tsis kam ntawm nws pib qhov chaw
Lub cav piston kub yog siab dhau lawm thiab overheating yog ib qho yooj yim los tsim chim tuav; Roj hmab foob, V- txoj siv sia, lub log tsheb, thiab lwm yam yog overheated, nws yuav ua rau kev laus thaum ntxov, txo kev ua haujlwm thiab ua haujlwm luv luv; Cov coils ntawm starter, generator, regulator thiab lwm yam khoom siv hluav taws xob yog overheated thiab yooj yim rau hlawv. Cov bearings ntawm cov tsheb scrapped yuav tsum tau khaws cia ntawm qhov kub thiab txias. Thaum overheated, cov roj lubricating yuav deteriorate sai, thiab thaum kawg cov bearings yuav hlawv thiab tsheb yuav puas.
3. Auto qhov chaw ntshai txoj hlua
Various couplings of diesel engine system, master-slave gears in the main reducer of drive axle, hydraulically operated valve block and valve rod, valve body and sleeve of full hydraulic steering, etc. These couplings are specially processed and ground in pairs during manufacture. They are very precise. They have been used in pairs throughout their service life and must not be replaced. Piston and cylinder liner, bearing bush and journal, valve and valve seat, connecting rod cylinder head, bearing cap and shaft and other meshing components mesh relatively well with the passage of time. During maintenance, attention should also be paid to assembly in pairs to avoid "approaching" each other.
4. Ntshai tsis kam
Thaum txhim kho lub cav ncoo, tsis txhob nruab nws nyob rau hauv qhov kev taw qhia. Txwv tsis pub, nws yuav ua rau ntxov ablation puas. Rau qee lub nplhaib piston nrog cov duab tshwj xeeb, lawv tsis tuaj yeem ntsia rov qab. Thov sib sau ua ke raws li qhov yuav tsum tau ua ntawm cov qauv sib txawv; Lub installation ntawm kiv cua hniav kuj muaj cov kev xav tau kev coj ua. Feem ntau, muaj ob hom kiv cua: tso pa thiab nqus. Thov tsis txhob ua qhov opposite. Txwv tsis pub, cov cua kub dissipation ntawm lub cav yuav ua rau mob hnyav thiab qhov kub thiab txias siab dhau lawm. Rau cov log tsheb nrog cov qauv kev taw qhia zoo ib yam li cov log tsheb herringbone, txhawm rau kom muaj kev tsav tsheb loj, cov kab hauv av tom qab kev teeb tsa yuav tsum ua rau pem hauv ntej kawg ntawm herringbone ntsej muag tom qab. Ob lub log tsheb sib xyaw ua ke muaj qhov sib txawv raws li cov tsheb sib txawv, yog li lawv tsis tuaj yeem ntsia tau yooj yim.
5. Ntshai tsis muaj peev xwm
When repairing the vehicle, some small objects may accidentally Miss installation. In addition, some people think that it doesn't matter whether it is installed or not. This is very dangerous and harmful. The door locks of the engine must be installed in pairs. For example, sometimes the valve is out of control and damaged by collision with the piston due to missing or missing installation; If there is leakage in the installation of locking devices such as cotter pins, locking screws, bumpers or spring pads installed on engine connecting rod bolts, flywheel bolts and transmission shaft bolts, serious faults may be caused in use. If the oil nozzle used to lubricate the gears in the engine timing gear chamber leaks, the oil leakage from there will become serious and the pressure of the engine oil will become low. If the box cover, oil cover and oil cover are lost, gravel and dust will invade and aggravate the wear of various parts.
6. Roj ntshai kuv
The paper filter element of the dry filter has strong moisture absorption. Once the oil is attached, the mixture with high concentration is easy to be sucked into the cylinder, resulting in insufficient air volume, deterioration of fuel consumption rate, decline of engine output power, and possibly "flying" of diesel engine. If the oil is attached to the triangular tape, it will promote corrosion deterioration, slip easily and reduce the transmission efficiency. If the brake pad, friction plate of dry clutch and brake belt are attached with oil, it is easy to slip or act poorly, threatening driving safety; If the carbon brushes of the starting motor and generator are attached with oil, poor contact will lead to insufficient power of the starting motor and voltage drop of the generator. The rubber of the tire is very sensitive to the corrosion of oil. When contacting with oil, the rubber will become soft and peeling. Short time contact will lead to abnormal and serious damage to the tire.
7. Ntshai ntawm kev rov ua dua
Some parts should be disposable, but if individual drivers or repairmen reuse them in order to save or do not know the "taboo", it is easy to cause accidents. Generally speaking, after removing the engine connecting rod bolts, nuts, fixing bolts of imported diesel engine fuel injector, water retaining ring of cylinder liner, sealing copper gasket, various oil seals, sealing rings of hydraulic system, pins and split pins of important parts, the engine cylinder gasket is not damaged during inspection, but it is replaced with a new one. The old ones have poor elasticity, poor sealing and easy aging. They also need to be replaced after long-term use, which is very troublesome. Therefore, if there is a new one, it is better to replace it as much as possible.
8. Tsis compression
Lub raj sab nraud ntawm lub log tsheb yuav tsum tau muab tso rau thiab khaws cia rau lub sijhawm ntev. Yog hais tias nws tsis tau tig mus rau hauv lub sij hawm, nws yuav deformed vim extrusion thiab cuam tshuam rau lub neej kev pab cuam; Cov ntawv lim cov ntsiab lus ntawm huab cua lim thiab roj lim yuav deform zoo heev thaum stamping, yog li lawv tsis tuaj yeem ua lub luag haujlwm ntawm cov lim dej kom ntseeg tau; Roj foob, daim kab xev daim duab peb sab, cov yeeb nkab cua, thiab lwm yam yuav tsum tsis txhob nias. Tom qab nias, nws tseem yuav deform thiab cuam tshuam rau kev siv ib txwm.
9. Ntshai hluav taws
Auto qhov chaw muaj xws li log tsheb, daim kab xev daim duab peb sab, lub tog raj kheej liner dej tuav lub nplhaib, roj hmab roj foob thiab lwm yam khoom siv roj hmab. Yog tias lawv nyob ze rau qhov qhib hluav taws, lawv yooj yim rau kev laus, deterioration thiab puas. Ntawm qhov tod tes, lawv kuj yuav ua rau muaj hluav taws kub. Tshwj xeeb, qee lub tsheb diesel nyuaj pib vim lub caij ntuj no txias. Qee tus neeg tsav tsheb yuav tsum tau ua kom sov nrog cov burners kom tsis txhob hlawv cov kab, roj circuits, thiab lwm yam.
10. I'm afraid of washing clothes
Qee cov neeg uas pib tsav tsheb lossis kho qhov chaw pib yuav xav tias txhua qhov chaw yuav tsum tau ntxuav, tab sis qhov tseeb, qhov kev nkag siab no yog ib qho - ib sab. Rau cov ntawv lim cua ntawm lub cav, tsis txhob siv cov roj los ntxuav cov plua plav ntawm nws. Tsuas yog coj mus rhaub maj mam nrog koj txhais tes los yog tshuab tawm siab - cua siab los ntawm sab hauv thiab sab nraud ntawm lub lim. Rau cov tawv nqaij, tsis tas yuav ntxuav lawv nrog roj, tsuas yog so lawv nrog ib daim ntaub huv.
