Isebenza njani iValve yoLawulo loBushushu

Intshayelelo: Kutheni Ulawulo Lobushushu Lubalulekile

Ukususela kwiinkqubo ze-HVAC kwizakhiwo ukuya kwi-automation yemizi-mveliso, izixhobo zelebhu, ukulungiswa kokutya, kunyeivalvuusetyenziso, iinkqubo zokulawula ubushushu zikho kuyo yonke indawo. Zinoxanduva lokugcina iindawo zikhululekile, iimveliso zihambelana, kunye noomatshini abasebenza ngaphakathi kwemida ekhuselekileyo.

Kodwa ulawulo lobushushu lusebenza njani ngokwenene? ​​Yintoni eyenza inkqubo iqonde utshintsho lobushushu kwaye ilungelelanise ngokufanelekileyo? Makhe sihlolisise iziseko zolawulo lobushushu oluzenzekelayo, kunye nendlela le nkqubo ingabonakaliyo edlala ngayo indima ebalulekileyo kubuchwepheshe banamhlanje.

Umgaqo-siseko oSebenzayo woLawulo loBushushu

Eyona nto iphambili, ulawulo lobushushu lumalunga nokulinganisa ubushushu bangoku, ukubuthelekisa nomlinganiselo othile, uze emva koko uthathe inyathelo lokulungisa nawuphi na umahluko (obizwa ngokuba “yimpazamo”).

Amanyathelo asisiseko ngala:

1. ①Ukulinganisa – Inzwa (njenge-thermocouple okanye i-RTD) ibona ubushushu bangoku.

2. ②Ukuthelekisa – Isilawuli sithelekisa ixabiso elilinganisiweyo nendawo efunekayo.

3. ③Ukulungiswa – Le nkqubo isebenzisa izixhobo zokufudumeza okanye zokupholisa ukunciphisa impazamo.

4. ④I-Replyback Loop – Uhlengahlengiso oluqhubekayo lwenziwa ukugcina ubushushu obufunekayo.

Izinto eziyinxalenye yeNkqubo yoLawulo loBushushu

1. Isivamvo sobushushu

   • ①Iintlobo eziqhelekileyo: ii-thermocouples, ii-RTD, ii-thermistors

   • ②Umsebenzi: Linganisa ubushushu bokwenyani benkqubo okanye okusingqongileyo.

2. Umlawuli

   • ①Isixhobo se-elektroniki okanye i-software logic esebenzisa ii-algorithms ezifana ne-PID (Proportional-Integral-Derivative) ukumisela ukuba kufuneka uhlengahlengiso olungakanani.

   • ②Ikhupha isignali kwi-actuator.

3. Isiqalisi/Isixhobo soLawulo

   • ①Izixhobo ezifana nezifudumezi, ii-cooler, iivalvu zokulawula ubushushu, okanye iifeni ezilungisa ubushushu.

4. Ukufakwa kweSeto sendawo

   • ①Ubushushu ekujoliswe kubo bungeniswa ngesandla okanye busetwe ngokuzenzekelayo ngesoftware.

5. Indlela yokuphendula

   • ①Iqinisekisa ukuba imilinganiselo yexesha langempela ikhokela iimpendulo zenkqubo rhoqo.

Indlela Ulawulo Lobushushu lwe-PID Olusebenza Ngayo

Isilawuli se-PID yeyona algorithm isetyenziswa kakhulu kulawulo lobushushu bemizi-mveliso ngenxa yokuchaneka kwayo kunye nokuphendula kwayo.

• ①Ukulinganisela: Ilungisa imveliso ngokusekelwe kubungakanani bempazamo.

• ②Integral: Isusa iimpazamo ezishiyekileyo ngokubala isimbuku seempazamo zangaphambili.

• ③Imvelaphi: Iqikelela iimpazamo zexesha elizayo ngokusekelwe kwisantya sotshintsho.

Izicelo zoLawulo loBushushu kwiShishini

1. ①Iinkqubo zeHVAC – Gcina intuthuzelo yangaphakathi ngokulungelelanisa ubushushu bomoya ngokuzenzekelayo.

2. ②Ukubumba Ngenaliti – Ubushushu obuchanekileyo bokubumba buphucula umgangatho wemveliso.

3. ③Ukutya Neziselo – Gcina upheka kakuhle, ukucoca, okanye ubushushu bokugcina.

4. ④Ukucubungula iikhemikhali – Qinisekisa ukuba iintshukumo zenzeka kwiimeko ezifanelekileyo zobushushu.

5. ⑤Izityalo zamandla – Lawula amaqondo obushushu e-turbine kunye ne-boiler ukuze kukhuseleke kwaye kusebenze kakuhle.

6. ⑥Ishishini leeValve – Sebenzisa iivalve zokulawula ubushushu ukulawula ubushushu bolwelo kwimibhobho.

Ulawulo lobushushu olukrelekrele nolwedijithali

Ngokukhula kwe-IoT (i-Intanethi yezinto) kunye nokuveliswa kwezinto ngobuchule, ulawulo lobushushu luye lwaphucuka ngakumbi:

• ①Iilawuli zobushushu zedijithali ezinee-interfaces zesikrini sokuchukumisa

• ②Ukubeka esweni kude ngokusebenzisa amaqonga asekelwe kwilifu

• ③Iinkqubo zokuzifundela eziziqhelanisa notshintsho lwendalo

• ④Izinzwa ezingenazingcingo kwiinethiwekhi zolawulo lobushushu ezisasazwe

Kwenzeka ntoni ngaphandle koLawulo olufanelekileyo lobushushu

• ①Ubushushu obugqithisileyo bungonakalisa izixhobo, bungonakalisa izinto, okanye bubangele imililo.

• ②Ukufudumala ngaphantsi kwendlu kunokukhokelela kwiinkqubo ezingaphelelanga okanye umgangatho wemveliso ophantsi.

• ③Ukungazinzi kobushushu kubangela ukuguquguquka kokusebenza, inkunkuma yamandla, kunye neengozi zokhuseleko.

Nokuba yiyunithi ye-HVAC, injini yedizili, umgca wokuvelisa amayeza, okanye inkqubo yevalvu yebhabhathane, ulawulo lobushushu luqinisekisa ukuthembeka, ixesha elide, kunye nokusebenza kakuhle.
