Dab tsi ua rau Diesel Genset Failure Alarms

Diesel generator teeb yog cov khoom siv hluav taws xob tsim hluav taws xob, nws siv cov roj diesel, tsav los ntawm lub tshuab hluav taws xob los tsim hluav taws xob.Tag nrho cov txheej txheem ntawm lub tshuab hluav taws xob diesel feem ntau yog tsim los ntawm lub tshuab hluav taws xob diesel, lub tshuab hluav taws xob, tswj txee, roj tank, cia roj teeb rau kev pib thiab tswj, cov cuab yeej tiv thaiv, txee thaum muaj xwm ceev thiab lwm yam khoom.

Lub tswb muaj nuj nqi ntawm lub tshuab hluav taws xob diesel yuav cia li pib thiab suab thaum lub tshuab hluav taws xob diesel muaj cov xwm txheej hauv qab no:

1. Tshaj ceev.

2. Cov dej kub kub hauv lub tank dej.

3. Tsawg roj siab.

4. Tshaj tam sim no tso saib ntawm lub vaj huam sib luag tswj.

5. Tshaj voltage.

6. Thaum lwm yam tshwm sim txawv txav tshwm sim, lub tswb ua haujlwm ntawm lub tshuab hluav taws xob diesel pib lossis kev tiv thaiv tus kheej ntawm lub tshuab hluav taws xob diesel plays lub luag haujlwm.

Yuav ua li cas yog vim li cas ntawm faults rau low voltage kaw?

1.Mechanical ceev tswj ntawm diesel cav

Diesel cav ceev cov cai muaj xws li hluav taws xob ceev kev tswj thiab mechanical ceev tswj.Yog tias nws yog kev tswj hwm kev ceev, muaj cov roj twj tso kua mis ntawm lub tshuab hluav taws xob los tswj cov roj ntim thiab cov roj hluav taws xob, nws zoo li hu ua common rail oil pump.Nws muaj lub pas nrig rub los tswj cov roj kom muaj nuj nqis.Nws yog hu ua ceev regulating rub pas nrig ib ntus.Ib qho kev txwv ceev (high-speed) sab saum toj pas nrig thiab ceev tswj cov pas nrig sab saum toj yog muab faib rau ntawm ob sab ntawm qhov ceev tswj rub pas nrig, thiab qhov qis siab yuav raug tshaj tawm tom qab pib thiab khiav rau 20s.Yog hais tias qhov voltage thiab zaus tseem tsis nyob rau hauv ib txwm muaj nqi, vim li cas tej zaum yuav ceev.Peb tuaj yeem sim kho cov kev cai sab saum toj pas nrig.Yog hais tias diesel genset muaj faults, yuav tsum muaj ib tug loj txhaum.Tom qab daws qhov txhaum loj, txhua yam teeb meem yuav raug daws.

2. Voltage qauv kab xoob

Yog hais tias cov kab yog xoob, yuav tsis muaj voltage.

3.Residual hlau nplaum

Yog tias lub tshuab hluav taws xob tsis muaj qhov seem hlau nplaum, qhov hluav taws xob ntawm lub tshuab hluav taws xob tsis tuaj yeem tsim thaum pib.Rau qhov teeb meem no, peb yuav tsum paub ntau npaum li cas voltage qhov excitation tso zis ntawm AVR regulator phaj ntawm lub tshuab hluav taws xob yog, thiab ces txuas tus coj voltage qhov chaw ntawm excitation tso zis kab rau magnetization (qhov voltage hom yuav tsum sib xws, thiab lub polarity yuav tsum. tsis tau rov qab).

3.Grounding txhaum

Yog hais tias cov kab tawm yog peb-theem hauv av, qhov voltage thiab tam sim no tsawg heev.Lub sijhawm no, nws yog qhov tseem ceeb los xyuas seb cov khoom siv hauv av (xws li riam hauv av) raug kaw lossis hauv av.

4.Regulating phaj txhaum

Vim qhov kev hloov pauv ntawm ib puag ncig, qhov tsis sib xws ntawm AVR siab tswj phaj tsis siv tau lawm thiab yuav tsum tau hloov kho.Feem ntau hais lus, qhov teeb meem zoo li no yuav tsis tshwm sim nyob rau hauv uas tsis yog parallel diesel gensets.Vim tias qhov tsis sib xws ntawm lub siab tswj lub phaj yog tus nqi ruaj khov (400V), peb tsis tuaj yeem kho lawv feem ntau.Tsuas yog lub tsev siv rau kev ua haujlwm sib luag tuaj yeem muaj qhov teeb meem no.Vim hais tias AVR voltage regulator yog tswj raws li qhov voltage ntawm lub tsheb npav tseem ceeb thaum lub sij hawm ua hauj lwm ua ke, nws tsis hloov pauv.Lub sijhawm no, muaj qhov hluav taws xob tswj hluav taws xob xa mus rau AVR voltage regulator los ntawm cov khoom siv ua haujlwm sib luag.Nyob rau hauv cov ntaub ntawv no, los xyuas seb lub voltage regulating teeb liab txuas tsis ncaj ncees lawm los yog sim siv hluav taws xob tswj (parallel operation device, voltage regulator, etc.) los kho qhov voltage sai sai thaum pib.

5.Lub varistor lossis rectifier choj diode ntawm lub tshuab hluav taws xob winding puas lawm

Lub luag haujlwm ntawm varistor yog tig rau ntawm varistor thaum muaj kev ua txhaum dhau-voltage kom txo qhov voltage.Yog tias lub varistor tawg lossis tig rau lwm yam laj thawj, nws tuaj yeem xav txog tias qhov voltage yuav tsum tsawg heev.Tus choj rectifier muaj 6 diodes.Lub teeb DC fais fab mov yog siv los muab cov regulator thiab excitation li.Yog hais tias lub rectifier choj diodes puas lawm, kev ua haujlwm ntawm cov regulator thiab excitation li yuav tsis muaj zog heev buckle.

Vam tias cov ntaub ntawv saum toj no yuav pab tau rau koj.Peb kuj muab tag nrho cov tshuab hluav taws xob diesel, peb muaj peb lub Hoobkas hauv Nanning Tuam Tshoj txij li xyoo 2006.
