Tso lus

I. Kev Npaj Ua Ntej Pib (Pre-cov kauj ruam, Ua ntej Ignition)
1. Tshawb xyuas cov roj, roj cav, thiab cov dej txias; los ntshav cov roj kab.
2. Qhib lub zog pib thiab cia lub kaw lus tswj nws tus kheej- kuaj xyuas: roj teeb voltage, dej kub thiab roj siab sensors, ceev sensor, voltage transformer, thiab kev tiv thaiv module yog txhua yam.
3. Qhib qhov tsis siv -load hloov (tsis txhob txuas lub load), thiab fais fab rau tus tswv xeev thiab AVR (Automatic Voltage Regulator) rau standby.
4. Phau ntawv chav nyob: nias lub pre- roj twj tso kua mis los tsim lub cav roj siab; automated units ua tsis siv neeg ua ntej -lubrication.
II. Ignition thiab Start Stage (Diesel Cav Ignition)
1. Tswj qhov system tso tawm cov teeb liab txuas rau lub cev muaj zog lub cev muaj zog; lub roj teeb tsav lub cev muaj zog tig lub cav diesel crankshaft.
2. Lub crankshaft tsav lub camshaft; lub siab- lub twj tso kua mis siab pib pib siv roj, thiab cov roj diesel raug xa los ntawm cov kab siab - cov roj hluav taws xob mus rau cov twj tso kua mis.
3. Pistons compress cua hauv lub tog raj kheej; compression xaus nrog kub ntawm 500-700 degree, mus txog diesel tus kheej -ignition point.
4. Siab- siab diesel yog atomized los ntawm cov injectors rau hauv lub tog raj kheej kub, qhov twg lub diesel pib- ignites (diesel engine tsis muaj lub txim plugs; ignition yog compression-raws li, feem ntau hu ua "pib ignition" nyob rau hauv kev lag luam).
5. Lub tog raj kheej tsim hluav taws xob; lub cav diesel khiav ntawm nws tus kheej combustion, tso lub oob khab lub cev muaj zog, uas disengages ntawm flywheel.
6. Lub sijhawm no, lub cav diesel yog qhov pib qis; roj siab thiab dej kub tseem tsis tau mus txog qib txheem.
III. Idle Warm- nce qib
1. Tus tswv xeev tswj kev txhaj tshuaj roj kom tsis txhob muaj qhov nrawm nrawm (feem ntau 600-800 r / min).
2. Lub cav roj siab maj mam nce mus rau qhov ntsuas tus nqi, qhov kub thiab txias nce, thiab cov khoom siv cua sov sib npaug los tiv thaiv qhov txias - cav hnav.
3. Lub tshuab hluav taws xob tig maj mam sib txuas nrog lub crankshaft; Lub tshuab hluav taws xob excitation winding tau txais qhov tsis muaj zog pib tam sim no los ntawm AVR, inducing low residual voltage hauv stator.
4. Lub kaw lus tswj xyuas: yog tias cov roj siab qis dhau, dej kub siab dhau, lossis overspeed tshwm sim, lub cav nres tam sim ntawd rau kev tiv thaiv.
5. Sov- lub sij hawm nce yog 30s–3min (ntev dua rau cov cav txias); ib zaug roj siab thiab dej kub yog qhov ruaj khov thiab ua tau raws li cov qauv, kev tso cai nrawm nrawm.
IV. Accelerating, Building Pressure, thiab Stabilizing Voltage Stage (Generator ncav cuag Voltage)
1. Tus tswv xeev nce cov khoom siv roj, nce lub cav diesel kom nrawm nrawm:
- 50Hz industrial units:1500 r / min (4-ncej generators, mainstream hauv kev lag luam hauv tsev)
- 60Hz units:1800 r / min
2. Generator rotor synchronizes rau rated ceev:
AVR cia li nce excitation tam sim no, ua ib tug muaj zog magnetic teb nyob rau hauv lub rotor; lub stator winding txiav cov kab sib nqus ntawm lub zog, thiab induced voltage sai sai.
3. Voltage nce mus rau tus nqi ntsuas (feem ntau peb-theem 400V / ib zaug-theem 230V); AVR tsis tu ncua zoo -tunes excitation tam sim no kom stabilize cov zis voltage.
4. Lub kaw lus tswj tau sau cov cim hluav taws xob thiab zaus kom paub meej tias qhov hluav taws xob ruaj khov (380/400V) thiab zaus (50Hz), nkag mus rau cov xwm txheej npaj.

V. Kaw qhov hloov mus rau qhov tso zis hluav taws xob (sab nraud fais fab mov)
Muaj ob txoj haujlwm ua haujlwm:ib zaug -unit ywj siab ua haujlwm thiab kab sib chaws- txuas ua haujlwm:
1. Ib leeg- lub tshuab hluav taws xob standby (ib txwm rau thaj chaw nyob / chaw tsim khoom)
1. Paub meej tias qhov voltage, zaus, thiab tag nrho cov kev tiv thaiv tsis muaj lub tswb;
2. Manually/automatically kaw qhov tso zis cua hloov (circuit breaker);
3. Peb-theem AC raug xa mus rau cov khoom siv thauj khoom los ntawm cov keyboards thiab cables, thiab lub tshuab hluav taws xob pib tawm hluav taws xob tawm sab nraud;
4. Ua haujlwm ntawm lub teeb load thawj zaug, tom qab ntawd maj mam nce lub load kom tsis txhob muaj kev thauj khoom sai sai uas yuav ua rau kom ceev lossis voltage poob.
2. Daim phiaj- txuas lub tshuab hluav taws xob (sib npaug nrog lub zog hluav taws xob)
Cov txheej txheem synchronization hauv qab no yuav tsum tau ua raws li: sib npaug voltage, tib zaus, sib npaug theem, thiab tib theem sib lawv liag;
1. Cov cuab yeej synchronization kho lub tshuab hluav taws xob ceev thiab qhov hluav taws xob kom phim cov khoom siv hluav taws xob;
2. Kaw daim phiaj -kev sib txuas ntawm lub sijhawm synchronization, cia lub tshuab hluav taws xob muab lub zog ua ke nrog daim phiaj;
3. Faib lub zog ua kom muaj zog / rov ua haujlwm raws li qhov kev faib tawm.
6. Ib txwm nyob ruaj khov-Lub Xeev Lub Zog Tsim Kev Ua Haujlwm
1. Diesel Cav Sab:
Thaum lub load nce → tsis kam nce → ceev me ntsis txo → tus tswv xeev cia li nce roj txhaj tshuaj kom rov qab 1500 r / min; thaum lub load txo, roj mov yog txo kom stabilize ceev thiab zaus.
Cov cua txias thiab lubrication tshuab txuas ntxiv mus, thiab qhov kub thiab txias - kiv cua tswj tau pib lossis nres raws li dej kub.
2. Generator Hluav Taws Xob Sab:
Load fluctuations ua rau cov zis voltage hloov, thiab AVR kho cov excitation tam sim no nyob rau hauv tiag-lub sij hawm kom ntseeg tau tias cov zis voltage fluctuations nyob rau hauv ± 5%.
3. Tswj System Nruam Saib Xyuas:
Roj siab, dej kub, ceev, voltage, tam sim no, lub hwj chim, overload, luv luv Circuit Court, to, thiab lwm yam yog tsis tu ncua saib xyuas, thiab tej yam txawv txav ua rau tam sim ntawd ceeb toom los yog breaker mus txawv tebchaws kaw rau kev tiv thaiv.

Qhov Tseem Ceeb Ntxiv Qhov yuam kev
1. Diesel cav tsis ignite nrog lub txim taws; lawv cia siab rau qhov siab -kub compression ntawm huab cua rau compression ignition. Cov kab lus niaj hnub 'ignition pib' tsuas yog lo lus sib tham xwb.
2. Lub tshuab hluav taws xob tsis tso tawm hluav taws xob tam sim ntawd thaum pib: ntawm qhov ceev qis, tsuas muaj qhov hluav taws xob seem, thiab nws yuav tsum ncav cuag qhov ntsuas ceev thiab tsim kom muaj zog ua ntej nws tuaj yeem muab lub zog.
3. Lub cav yuav tsum tau sov so ua ntej muab lub zog; khiav ntawm tag nrho load thaum txias yuav txo qhov voltage thiab nce cav hnav.
