Load Operation Of Volvo Diesel Generators

1. Taw qhia rau lub suab sib sib zog nqus

Sib sib zog nqus ncov shaving yog ib hom kev lag luam hom nyob rau hauv uas cov zis ntawm cov fais fab nroj tsuag raug txo thiab lub generator teev ntau tshaj qhov yooj yim ncov shaving nplai vim qhov loj ncov-kav qhov sib txawv ntawm daim phiaj load.Lub load scale ntawm kev sib sib zog nqus ncov tswj tshaj qhov siab tshaj plaws ruaj khov combustion load ntawm lub boiler ntawm lub fais fab nroj tsuag (feem ntau, lub ncov txoj cai qhov tob ntawm lub ncov ncov txoj cai yog 60% -70% BMCR).Tam sim no, thee-hluav taws xob thermal fais fab qhia tau hais tias tus yam ntxwv ntawm kev nce tus naj npawb ntawm cov koom haum koom nrog kev tswj hwm lub siab tshaj plaws lossis kev sib kho, txo cov sijhawm ua haujlwm thiab cov nqi qis hauv chav tsev.

Lub ncov-shaving ua haujlwm hom ntawm thee-tawm hluav taws xob thermal fais fab chav tsev ntawm lub tshuab hluav taws xob tsim hluav taws xob yog qhov sib txawv ntawm kev ua haujlwm, thiab cov chaw tsim khoom siv hluav taws xob kho qhov hnyav tshaj qhov kev hloov kho qhov tob, thiab cov khoom hloov pauv sai.

Yav dhau los, lub hauv paus ntsiab lus ntawm kev npaj lub peev xwm loj thee hluav taws xob hluav taws xob hluav taws xob hluav taws xob tau ua haujlwm ntev ntev nrog lub hauv paus load, thiab lub hom phiaj yog yuav ua li cas los txhim kho cov cua txias ntawm stator winding thiab stator core, thiaj li yuav txhim kho cov zis. hwj chim thiab tsis muaj lub cev muaj zog nyob rau hauv tag nrho load mob.Txawm li cas los xij, vim muaj kev hloov pauv ntawm qhov chaw ua haujlwm sab nraud ntawm daim phiaj hluav taws xob, kev ua haujlwm ntawm lub tshuab hluav taws xob yog qhov txawv ntawm yav dhau los.Lub sij hawm thiab zaus ntawm kev tswj hwm siab tshaj plaws, kev tswj xyuas siab thiab theem nkag mus rau kev ua haujlwm tau nce ntau.Txawm hais tias thaum pib ntawm kev npaj lub tshuab hluav taws xob, cov kev cuam tshuam ntawm ntau qhov chaw ua haujlwm ntawm lub tshuab hluav taws xob tau txiav txim siab thiab cov kev ntsuas sib raug tau raug coj los tiv thaiv lawv, qhov tseeb, ob peb lub peev xwm loj turbogenerators ua haujlwm nyob rau hauv lub sijhawm ntev thiab kev tswj xyuas siab nrog rau cov theem nkag. , thiab kev tsom xam mechanism ntawm cov qauv kev ua haujlwm hauv kev lag luam tsis txaus.

2. Kev sib piv ntawm kev cuam tshuam ntawm kev ua haujlwm ib txwm muaj thiab qhov tob ntawm kev hloov pauv ntawm stator thiab rotor windings thiab hlau tub ntxhais ntawm lub tshuab hluav taws xob

Hauv Guangxi Dingbo Power Equipment Manufacturing Co., Ltd, muaj 8 thee-fired turbogenerators hauv kev pabcuam, ntawm cov 635MW thiab 1000MW generators tau koom nrog kev sib sib zog nqus.Raws li cov teeb meem tshwm sim hauv kev sib sib zog nqus, lub tshuab hluav taws xob sib dhos thiab rotor raug tshuaj xyuas kom meej thaum txhua qhov kev kho loj thiab me.Thaum lub sij hawm sib sib zog nqus hloov, cov ntaub ntawv tsom xam yog tsom rau cov thermal expansion qhov sib txawv ntawm cov tub ntxhais hlau thiab hlau pas nrig ntawm lub tshuab hluav taws xob sib dhos thiab rotor.Txhawm rau txheeb xyuas qhov cuam tshuam ntawm kev sib sib zog nqus ntawm kev hloov kho hluav taws xob, ua kev tshawb fawb thiab kev ntsuas.

2.1 Kev soj ntsuam ntawm cov kev ua txhaum cai ntawm lub tshuab hluav taws xob stator thiab rotor nyob rau hauv ib txwm ua haujlwm hom

2.1.1 Stator kawg yog xoob

Nyob rau hauv lub overhaul ntawm 1000MW chav tsev nyob rau hauv 2014, nws tau pom tias l-shaped bracket zawv zawg tus pin ntawm qhov kawg ntawm lub tshuab hluav taws xob stator tau hnav nyob rau hauv rau qhov chaw, lub bracket ntawm 10, 11, 12, 1, 2, 4 thiab 5 o ' moos nruab nrab ntawm stator zoo siab kawg bracket thiab lub nplhaib hlau tau hnav nyob rau hauv ntau qhov sib txawv, thiab cov hlau lead ntawm 11 o'clock ntawm qhov zoo siab kawg thiab lub nplhaib txhawb nqa tau hnav nrog cov hmoov daj me ntsis.Kev kho mob: ntxuav, xyuas, rov pib dua tus swb tus pin, thiab kho tus swb tus pin teeb.Tshem cov hlua khi ntawm lub nplhaib stator, ntxiv qhov kev ncua deb ntawm lub nplhaib hlau, thiab khi nws ruaj khov nrog φ 5 polyester yoj hlua khi rau hauv NAZ kua nplaum.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Suav teb, uas integrates tsim, muab, commissioning thiab txij nkawm ntawm diesel generator teeb.Cov khoom npog Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz , Ricardo, MTU, Weichai thiab lwm yam nrog lub hwj chim ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab lub chaw thev naus laus zis.
