Dab tsi ua rau lub roj teeb poob txias cranking amps?

Lub roj teeb tuaj yeem poob Cold Cranking Amps (CCA) dhau sijhawm vim muaj ntau yam, feem ntau cuam tshuam txog hnub nyoog, kev siv, thiab kev saib xyuas. Nov yog cov laj thawj tseem ceeb:

1. Sulfation

• Nws yog dab tsi: Kev tsim cov txhuas sulfate crystals ntawm cov roj teeb daim hlau.

• Ua rau: Muaj tshwm sim thaum lub roj teeb tso tawm lossis qis dua rau lub sijhawm ntev.

• nyhuv: Txo qhov chaw ntawm cov khoom siv, txo CCA.

2. Kev laus thiab phaj hnav

• Nws yog dab tsi: Ntuj degradation ntawm cov roj teeb lub sij hawm.

• Ua rau: Rov them rov qab thiab tawm lub voj voog tawm ntawm daim hlau.

• nyhuv: Cov khoom siv tsawg dua yog muaj rau cov tshuaj tiv thaiv, txo cov zis hluav taws xob thiab CCA.

3. Corrosion

• Nws yog dab tsi: Oxidation ntawm cov khoom sab hauv (xws li daim phiaj thiab cov terminals).

• Ua rau: Raug dej noo, cua sov, lossis kev saib xyuas tsis zoo.

• nyhuv: Hinders tam sim no ntws, txo lub roj teeb lub peev xwm xa cov tam sim no siab.

4. Electrolyte Stratification lossis Poob

• Nws yog dab tsi: Tsis sib npaug ntawm cov kua qaub hauv lub roj teeb lossis poob ntawm electrolyte.

• Ua rau: Kev siv tsis tu ncua, kev them nqi tsis zoo, lossis evaporation hauv cov roj teeb dej nyab.

• nyhuv: Ua rau cov tshuaj tsis haum tshuaj, tshwj xeeb tshaj yog nyob rau hauv huab cua txias, txo CCA.

5. Huab cua txias

• Nws ua li cas: Txo cov tshuaj tiv thaiv kab mob thiab ua kom muaj zog sab hauv.

• nyhuv: Txawm tias lub roj teeb noj qab haus huv tuaj yeem poob CCA ib ntus ntawm qhov kub thiab txias.

6. Overcharge lossis Undercharge

• Kev them nyiaj ntau dhau: Ua rau lub phaj poob thiab dej poob (hauv cov roj teeb dej nyab).

• Kev them nqi qis: Txhawb nqa sulfation buildup.

• nyhuv: Ob qho tib si ua rau lub cev puas tsuaj, txo CCA lub sijhawm.

7. Lub cev puas tsuaj

• Piv txwv: Kev vibration puas lossis poob roj teeb.

• nyhuv: tuaj yeem tshem tawm lossis tawg cov khoom siv sab hauv, txo CCA cov zis.

Cov lus qhia tiv thaiv:

• Khaws lub roj teeb kom tag.

• Siv lub roj teeb tswj xyuas thaum khaws cia.

• Tsis txhob tawm qhov tob tob.

• Txheeb xyuas cov qib electrolyte (yog tias tsim nyog).

• Ntxuav corrosion los ntawm terminals.

Koj puas xav tau cov lus qhia yuav ua li cas kuaj koj lub roj teeb CCA lossis paub thaum twg los hloov nws?
