Puas yog cov saw saw pib txawv txav?

2024-06-13 IB

Nws yog ib qho phenomenon uas tussaw sawmuaj teeb meem pib lossis tsis tuaj yeem pib thaum siv. Koj yuav daws qhov teeb meem no li cas?Yog tias koj xav kom cov saw hlau pib ib txwm, koj yuav tsum xyuas cov ntsiab lus hauv qab no:

[Cov ntsiab lus tseem ceeb]

Compression: Yuav kom tswj tau qhov zoo ntawm lub tog raj kheej siab, yuav tsum tsis txhob poob ntawm compression hauv lub tog raj kheej.

Ignition system: Thaum lub sij hawm ignition zoo, lub ignition system yuav tsum tsim ib tug muaj zog spark.

Roj system thiab carburetor: Cov huab cua-roj sib tov yuav tsum tau muab los ntawm kev sib xyaw kom zoo.

Yog li ntawd, thaum cov saw saw muaj teeb meem pib lossis tsis tuaj yeem pib, peb yuav daws qhov teeb meem ib los ntawm ib qho raws li cov hauv qab no:

1 Txheeb xyuas Compression: Kev kuaj mob pib sab nraud thiab xaus rau sab hauv

Sab nraud tej yam kev mob → nruj tej yam kev mob → lub tog raj kheej → piston → crankcase

Ua ntej xyuas seb lub qhov hluav taws xob puas nruj, thiab tom qab ntawd tig lub log pib (rub lub oob khab) ntawm tes. Thaum nws hla qhov chaw tuag saum toj kawg nkaus (them maj mam rub lub oob khab 1-2 tig), nws xav tias muaj zog ntau dua (tuaj yeem muab piv nrog lub tshuab tshiab), thiab Tom qab tig rau saum qhov chaw tuag (tom qab lub tshuab tig ob peb zaug), lub log pib tuaj yeem hloov tau los ntawm lub kaum sab xis loj dua (nws yuav tig mus txuas ntxiv yam tsis rub lub oob khab), qhia tias qhov compression yog qhov qub. Yog tias lub piston tig dhau los ntawm qhov chaw tuag saum toj kawg nkaus sai lossis yooj yim, nws txhais tau tias lub tog raj kheej compression quab yuam tsis txaus. Qhov teeb meem nyob hauv: qhov teeb meem roj cav ua rau lub tog raj kheej hnav lossis lub tog raj kheej rub; lub tog raj kheej thaiv thiab crankcase gasket yog to.

 

2 Cov teeb meem hauv Circuit Court: Kev kuaj xyuas pib thaum tawm thiab xaus ntawm ImportSpark plug → spark plug cap → hloov → high voltage, av xaim thiab hloov xaim → ignition coil → flywheel

Yog tias qhov compression zoo li qub, tsis muaj suab nrov hauv lub tog raj kheej (tsis muaj suab nrov) thaum pib lub saw saw, thiab cov pa tawm ntawm lub muffler yog ntub thiab tsw ntxhiab ntawm cov roj av, uas qhia tau hais tias muaj kev ua txhaum ntawm lub hauv paus system. Lub sijhawm no, lub txim hluav taws xob yuav tsum tau muab tshem tawm (xyuas lub qhov hluav taws xob qhov sib txawv ntawm 0.6 ~ 0.7 hli), txuas lub qhov hluav taws xob mus rau cov xaim hluav taws xob siab, nrog rau sab ntawm lub qhov hluav taws xob ze ze rau cov hlau ntawm lub tshuab lub cev. , thiab rub lub tshuab sai sai kom pom tias muaj cov xiav xiav. Yog tias tsis yog, ua ntej xyuas seb lub hau ntsaws ntsaws puas puas lawm, tom qab ntawd tshem tawm lub qhov hluav taws xob, ncaj qha siv lub tshuab hluav taws xob hluav taws xob kawg kom pom cov hlau ntawm lub cev txog 3 hli, rub lub oob khab, thiab saib seb puas muaj cov pa taws xiav dhia. dhau ntawm high-voltage hlau. Yog tias tsis yog, nws txhais tau hais tias muaj teeb meem nrog lub pob siab siab lossis flywheel.

 

  1. Xyuas cov roj system: pib ntawm qhov nkag thiab xaus ntawm qhov hluav taws xob

Roj tank hau → Roj → Exhaust valve → Roj lim → Roj yeeb nkab → Carburetor → Intake negative pressure pipe

Yog hais tias lub hauv paus system yog ib txwm, nws yog lub sij hawm los xyuas cov roj mov system. Yog tias tsis muaj suab nrov hauv lub tog raj kheej thaum pib, cov yeeb nkab tso tawm tsis muaj zog, thiab cov pa roj yog qhuav thiab tsis muaj ntxhiab tsw ntxhiab, nws feem ntau yuav qhia tau tias muaj teeb meem nrog cov khoom siv roj. Xyuas seb puas muaj roj txaus nyob rau hauv lub tank roj, seb cov roj lim puas raug thaiv tiag tiag, seb cov roj yeeb nkab puas tawg thiab tawg, thiab seb lub carburetor puas raug thaiv. Yog tias cov tshev no zoo tag nrho thiab koj tseem tsis tuaj yeem pib, koj tuaj yeem tshem tawm lub taub hau, ncuav ob peb tee roj av rau hauv lub qhov hluav taws xob (tsis ntau dhau), tom qab ntawd nruab lub qhov hluav taws xob thiab pib lub saw saw. Yog tias nws tuaj yeem pib thiab khiav ib ntus, nws txhais tau hais tias lub carburetor yog txhaws hauv. Koj tuaj yeem disassemble lub carburetor rau tu lossis hloov.

41-Tsis muaj 3 qhov xwm txheej

Yog tias txhua yam uas tau hais los saum toj no yog qhov zoo, koj yuav tsum xav txog seb qhov chaw pib qhov chaw kub li cas qis dhau.

Tej zaum vim tias lub tshuab txias dhau lawm, cov roj av tsis yooj yim rau atomize thiab nws tsis yooj yim los pib. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau txiav txim siab seb lub crankcase muaj kev sib khi tsis zoo vim kev puas tsuaj rau cov roj foob. Thaum lub ambient kub qis, lub damper yuav tsum tau kaw me ntsis. Thaum lub ambient kub siab, lub damper yuav tsum tau qhib tag nrho ua ntej pib.

  1. Roj av ratio ua rau tsis ua hauj lwm Yog tias cov roj piv ntawm cov saw saw tsis zoo los yog muaj cov pa roj carbon ntau ntau hauv cov muffler, nws tseem yuav ua rau cov saw saw tsis yooj yim pib lossis tsis pib. Ntxuav nws ntau zaus kom tshem tawm cov plua plav tawm ntawm muffler, cua lim, thiab lub cev. Qib tsis raug lossis tsis zoo ntawm cov roj av thiab cov roj cav kuj tseem cuam tshuam rau kev pib lub tshuab. Lawv yuav tsum tau teeb tsa thiab xaiv raws li qhov yuav tsum tau muaj nyob rau hauv phau ntawv saw saw.

Cov txheej txheem pib thiab cov txheej txheem

Cov kev taw qhia thiab cov txheej txheem ntawm kev pib rub hlua thiab qhov pib nrawm (yuav nrawm npaum li cas koj rub lub oob khab) kuj muaj kev cuam tshuam rau qhov pib ntawm cov saw saw.

Kuv yuav ua li cas yog tias cov saw saw tuaj yeem pib ib txwm tab sis qhov ceev tsis tuaj yeem ncav cuag lossis cov pa roj pedal?Thov tshawb xyuas ntxiv

Roj:

  1. Xyuas seb lub tshuab lim cua puas yog txhaws, ntxuav lossis hloov nws;
  2. Lub taub hau lim roj yog txhaws, tsuas yog hloov nws;
  3. Kev siv roj tsis raug, siv roj kom raug;
  4. Kev hloov kho carburetor tsis raug. Pib dua lub koob roj thiab rov kho nws (tig H thiab L roj koob clockwise mus rau qhov kawg, tig lub H roj koob 1 thiab ib nrab mus rau 2 tig rov qab, thiab tig L roj koob 2 thiab 2 thiab ib nrab tig rov qab. ., yog tias qhov kev kub ceev tsis tuaj yeem ncav cuag, tig lub koob roj H clockwise 1/8 txhua zaus;
  5. Lub carburetor yog txhaws, ntxuav los yog hloov nws.

Exhaust System:

  1. Lub muffler yog clogged nrog carbon, khawb tawm cov pa roj carbon deposit los yog siv hluav taws los tshem nws
  2. Lub tog raj kheej tso chaw nres nkoj yog clogged nrog carbon deposits, scrape tawm cov pa roj carbon deposits

Circuit Court:

Lub pob high-voltage yog puas sab hauv thiab yuav tsum tau hloov.
