Lub Diesel Generator Ua Haujlwm Li Cas?
Diesel generators yog cov khoom siv hluav taws xob txhim khu kev qha uas hloov cov tshuaj siv hluav taws xob khaws cia hauv cov roj diesel rau hauv hluav taws xob. Lawv tau siv dav hauv ntau daim ntawv thov, los ntawm kev muab lub zog thaub qab thaum muaj xwm txheej ceev mus rau qhov chaw taws teeb uas tsis muaj hluav taws xob. Kev nkag siab tias lub tshuab hluav taws xob diesel ua haujlwm li cas suav nrog kev tshuaj xyuas nws cov khoom siv yooj yim thiab cov txheej txheem uas tshwm sim hauv lawv los tsim hluav taws xob.
Basic Cheebtsam ntawm Diesel Generator
Lub tshuab hluav taws xob diesel feem ntau muaj ob lub ntsiab lus: lub cav (tshwj xeeb, lub tshuab hluav taws xob) thiab lub tshuab hluav taws xob (lossis lub tshuab hluav taws xob). Cov khoom siv no ua haujlwm tandem los tsim hluav taws xob hluav taws xob.
- Diesel Cav: Lub cav diesel yog lub plawv ntawm lub tshuab hluav taws xob. Nws yog lub cav combustion uas hlawv roj diesel los tsim cov tshuab hluav taws xob nyob rau hauv daim ntawv ntawm rotating motion. Diesel cav paub txog lawv cov durability, roj efficiency, thiab tsis tshua muaj txij nkawm yuav tsum tau.
- Alternator: Lub alternator hloov cov tshuab hluav taws xob uas tsim los ntawm lub cav diesel rau hauv hluav taws xob. Nws ua qhov no los ntawm cov txheej txheem hu ua electromagnetic induction, qhov twg rotating magnetic teb tsim ib qho hluav taws xob tam sim no nyob rau hauv ib co coils raug mob nyob ib ncig ntawm ib tug hlau core.
Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob diesel tuaj yeem tawg ua ob peb kauj ruam:
- Roj Txhaj thiab combustion: Lub cav diesel ua haujlwm ntawm lub hauv paus ntsiab lus compression-ignition. Cua yog rub mus rau hauv lub cav lub tog raj kheej los ntawm cov khoom siv li qub thiab compressed mus rau qhov siab heev. Thaum lub ncov ntawm compression, roj diesel yog txhaj rau hauv lub tog raj kheej nyob rau hauv siab. Thaum tshav kub kub thiab siab ua rau cov roj ignite spontaneously, tso lub zog nyob rau hauv daim ntawv ntawm expanding gases.
- Piston Movement: Cov roj txuas ntxiv thawb lub pistons nqes mus, hloov lub zog hluav taws xob rau hauv lub zog siv tshuab. Cov pistons txuas nrog lub crankshaft los ntawm kev sib txuas cov pas nrig, thiab lawv cov nqes nqes tig tig lub crankshaft.
- Mechanical Zog Hloov: Lub rotating crankshaft txuas nrog lub alternator lub rotor (tseem hu ua armature). Raws li lub crankshaft rotates, nws tig lub rotor nyob rau hauv lub alternator, tsim ib tug rotating magnetic teb.
- Electromagnetic Induction: Lub rotating magnetic teb interacts nrog cov stator coils nyob ruaj ruaj nyob ib ncig ntawm lub alternator lub hlau core. Qhov kev sib cuam tshuam no ua rau muaj kev hloov hluav taws xob tam sim no (AC) hauv cov coils, uas tom qab ntawd muab rau cov khoom siv hluav taws xob lossis khaws cia rau hauv lub roj teeb rau kev siv tom qab.
- Kev tswj hwm thiab kev tswj hwm: Lub tshuab hluav taws xob tso zis hluav taws xob thiab zaus yog tswj hwm los ntawm kev tswj hwm, uas yuav suav nrog kev tswj hluav taws xob tsis siv neeg (AVR) thiab tus tswv xeev. AVR tswj cov zis hluav taws xob nyob rau theem tsis tu ncua, thaum tus tswv xeev kho cov khoom siv roj rau lub cav kom tswj tau qhov ceev tsis tu ncua thiab, yog li, qhov tso tawm tsis tu ncua.
- Txias thiab tso pa tawm: Lub tshuab hluav taws xob diesel ua kom muaj cua sov ntau thaum lub sij hawm combustion. Lub tshuab ua kom txias, feem ntau yog siv dej los yog cua, yog qhov tseem ceeb los tswj lub cav ua haujlwm kub hauv qhov txwv tsis pub muaj kev nyab xeeb. Tsis tas li ntawd, cov txheej txheem combustion tsim cov pa pa tawm, uas raug tshem tawm los ntawm qhov tso pa tawm.
