txhawm rau tswj thiab txhim kho kev ua haujlwm ntawm boiler units, kev txhais tau tias pib siv txawm tias thaum pib ntawm automation ntawm kev lag luam thiab kev tsim khoom. Cov theem tam sim no ntawm txoj kev loj hlob hauv cheeb tsam no tuaj yeem ua rau muaj txiaj ntsig zoo thiab kev ntseeg siab ntawm cov khoom siv boiler, ua kom muaj kev nyab xeeb thiab kev txawj ntse ntawm kev ua haujlwm ntawm cov neeg ua haujlwm tu.

hom phiaj thiab lub hom phiaj

Niaj hnub nimno boiler chav automation tshuab muaj peev xwm lav tsis muaj teeb meem thiab ua haujlwm tau zoo ntawm cov cuab yeej yam tsis muaj kev cuam tshuam ncaj qha rau tus neeg teb xov tooj. Tib neeg lub luag haujlwm raug txo qis rau kev saib xyuas hauv online ntawm kev ua tau zoo thiab cov kev txwv ntawm tag nrho cov khoom siv. Automation ntawm boiler tsev daws cov dej num hauv qab no:

  • Tsis siv neeg pib thiab nres ntawm boilers.
  • Txoj cai ntawm lub hwj chim boiler (cascade tswj) raws li qhov muab thawj zaug.
  • Kev tswj cov twj tso kua mis, tswj cov qibCov dej txias hauv kev ua haujlwm thiab cov neeg siv khoom siv hluav taws xob.
  • nres thaum muaj xwm txheej ceev thiab ua kom cov khoom siv teeb liab, yog tias qhov kev ua haujlwm ntawm qhov system mus dhau qhov kev txwv.

Automation Object

Boiler cov cuab yeej ua ib yam khoom ntawm kev tswj hwm yog ib qho kev ua haujlwm nyuaj nrog ntau qhov sib cuam tshuam cov tswv yim thiab cov khoom tso tawm. Lub automation ntawm boiler tsev yog nyuaj los ntawm qhov tseeb hais tias qhov ceev ntawm technologies txheej txheem nyob rau hauv chav tsev yog siab heev. Qhov tseem ceeb kho qhov tseem ceeb suav nrog:

  • tus nqi ntws thiab siab ntawm cov dej txias (dej lossis chav dej);
  • tso tawm hauv qhov cub;
  • qib tank qib;
  • Nyob rau xyoo tas los no, kev xav tau ib puag ncig tau nce ntxiv rau qhov zoo ntawm cov roj sib xyaw ua ke thiab, vim li ntawd, ntawm qhov ntsuas kub thiab muaj pes tsawg leeg ntawm cov khoom pa taws.

Automation theem

Qib ntawm automation yog teem thaum tsim lub tsev boiler lossis thaum kho dua / hloov khoom siv. Nws tuaj yeem ua tau los ntawm kev tswj hwm kev tswj hwm raws li cov lus qhia ntawm kev ntsuas mus rau kev tswj tsis siv neeg tag nrho raws li huab cua-dependent algorithms. Qib ntawm automation feem ntau txiav txim siab los ntawm lub hom phiaj, lub peev xwm thiab kev ua haujlwm ntawm cov khoom siv ua haujlwm.

Niaj hnub nimno automation ntawm chav boiler txhais tau hais tias ib qho kev sib koom ua ke - cov subsystems rau kev saib xyuas thiab tswj tus kheej cov txheej txheem thev naus laus zis tau ua ke rau hauv ib lub network nrog kev ua haujlwm.pab pawg tswj.

tag nrho cov qauv

Automation ntawm boiler tsev yog ua los ntawm ob-theem tswj tswvyim. Qib qis (teb teb) suav nrog cov khoom siv hauv zos automation raws li programmable microcontrollers uas siv kev tiv thaiv kev tiv thaiv thiab kev thaiv, kev hloov kho thiab kev hloov pauv ntawm cov tsis, thawj cov hloov pauv ntawm lub cev ntau. Qhov no kuj suav nrog cov cuab yeej tsim los hloov, encode thiab xa cov ntaub ntawv xov xwm.

Cov theem sab saud tuaj yeem sawv cev ua lub davhlau ya nyob twg ua rau hauv lub txee tswj lossis ua tus neeg teb xov tooj lub chaw ua haujlwm raws li lub khoos phis tawj tus kheej. Nws qhia tag nrho cov ntaub ntawv los ntawm qib qis microcontrollers thiab sensors ntawm lub kaw lus, thiab nkag mus rau cov lus txib, kev hloov kho thiab kev teeb tsa. Ntxiv nrog rau cov txheej txheem xa tawm, cov dej num ntawm optimizing hom, kuaj xyuas cov txheej txheem, kev txheeb xyuas kev lag luam, kev khaws cia thiab khaws cov ntaub ntawv raug daws. Yog tias tsim nyog, cov ntaub ntawv raug xa mus rau kev tswj hwm kev lag luam (MRP / ERP) lossis hauv zos.

Automation ntawm cov khoom siv boiler

Kev lag luam niaj hnub no tau nthuav dav los ntawm ob qho tib si cov cuab yeej thiab cov cuab yeej siv, nrog rau cov khoom siv hluav taws xob tsim hluav taws xob hauv tsev thiab txawv teb chaws rau chav dej thiab dej kub boilers. Cov cuab yeej Automation suav nrog:

  • ignition thiab nplaim taws tswj cov cuab yeej, pib thiabtswj cov txheej txheem ntawm cov roj combustion nyob rau hauv lub combustion chamber ntawm lub boiler chav tsev;
  • tshwj xeeb sensors (dav thiab ntsuas ntsuas, ntsuas kub thiab siab ntsuas, ntsuas roj, thiab lwm yam);
  • actuators (solenoid li qub, relays, servo drives, zaus converters);
  • tswj vaj huam sib luag rau boilers thiab cov khoom siv boiler dav dav (panels, kov cov ntxaij vab tshaus);
  • hloov cov txee, cov kab sib txuas lus thiab cov khoom siv hluav taws xob.

Thaum xaiv cov txheej txheem kev tswj hwm thiab saib xyuas, qhov ze tshaj plaws yuav tsum tau them rau kev nyab xeeb tsis siv neeg, uas tsis suav nrog qhov tshwm sim ntawm qhov xwm txheej kub ntxhov thiab xwm txheej ceev.

Subsystems thiab functions

Txhua chav boiler automation scheme suav nrog kev tswj, kev tswj hwm thiab kev tiv thaiv subsystems. Kev tswj hwm yog ua los ntawm kev tswj xyuas qhov zoo tshaj plaws combustion hom los ntawm kev teeb tsa lub tshuab nqus tsev nyob rau hauv lub qhov cub, thawj huab cua ntws tus nqi thiab cov coolant tsis (kub, siab, txaus tus nqi). Tus tswj subsystem tso tawm cov ntaub ntawv tiag tiag ntawm kev ua haujlwm ntawm cov cuab yeej siv rau tib neeg-tshuab interface. Cov cuab yeej tiv thaiv tau lees paub qhov kev tiv thaiv thaum muaj xwm txheej ceev thaum muaj kev ua txhaum ntawm kev ua haujlwm ib txwm muaj, muab lub teeb, lub suab teeb liab lossis kev kaw ntawm boiler units nrog kho qhov ua rau (ntawm cov duab kos duab, mnemonic daim duab, ntaub thaiv npog).

kev sib txuas lus raws tu qauv

Automation ntawm boiler nroj tsuag raws li microcontrollers txo qis kev siv hauv kev ua haujlwmdaim duab ntawm relay switching thiab tswj fais fab kab. Txhawm rau txuas mus rau theem siab thiab qis ntawm kev tswj hwm qhov system, hloov cov ntaub ntawv ntawm sensors thiab controllers, txhais cov lus txib rau actuators, kev lag luam network nrog ib qho tshwj xeeb interface thiab cov ntaub ntawv hloov chaw raws tu qauv yog siv. Cov qauv siv dav tshaj plaws yog Modbus thiab Profibus. Lawv tau sib xws nrog ntau ntawm cov cuab yeej siv los ua kom muaj cua sov. Lawv txawv los ntawm tus nqi siab ntawm kev ntseeg siab ntawm cov ntaub ntawv hloov chaw, yooj yim thiab nkag siab cov ntsiab lus ntawm kev ua haujlwm.

Kev txuag hluav taws xob thiab kev sib raug zoo ntawm automation

Kev siv lub tsev boiler tag nrho tshem tawm qhov muaj feem cuam tshuam nrog kev puas tsuaj ntawm cov tuam tsev peev, kev tuag ntawm cov neeg ua haujlwm pabcuam. ACS muaj peev xwm ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv nyob ib ncig ntawm lub moos, txo qis kev cuam tshuam ntawm tib neeg.

Raws li qhov pom ntawm qhov nce ntxiv ntawm cov nqi rau cov khoom siv roj, kev txuag hluav taws xob ntawm kev siv hluav taws xob tsis yog qhov tseem ceeb tshaj plaws. Txuag natural gas, nce mus txog 25% ib lub caij cua sov, yog muab los ntawm:

  • qhov zoo tshaj plaws "gas / cua" piv rau cov roj sib tov hauv txhua hom kev ua haujlwm ntawm lub tsev boiler, kho los ntawm qib ntawm cov ntsiab lus oxygen hauv cov khoom siv hluav taws xob;
  • lub peev xwm los kho tsis tau tsuas yog boilers xwb, tab sis kuj gas burners;
  • tswj tsis tau tsuas yog qhov kub thiab txias ntawm lub coolant ntawm lub inlet thiab qhov hluav taws xob boilers, tab sis kuj coj mus rau hauv tus account ib puag ncig tsis(xws li huab cua-compensated technology).

Ntxiv rau, automation tso cai rau koj los siv lub zog txuag hluav taws xob rau cov cua sov uas tsis yog nyob hauv tsev lossis cov tsev uas tsis siv rau hnub so thiab hnub so.
