Isebenza Kanjani I-Valve Yokulawula Izinga Lokushisa

Isingeniso: Kungani Ukulawula Izinga Lokushisa Kubalulekile

Kusukela ezinhlelweni ze-HVAC ezakhiweni kuya ekuzenzekeleni kwezimboni, imishini yelabhorethri, ukucubungula ukudla, kanyeivalvuizinhlelo zokusebenza, izinhlelo zokulawula izinga lokushisa zikhona yonke indawo. Zinesibopho sokugcina izindawo zikhululekile, imikhiqizo ihambisana, kanye nemishini isebenza ngaphakathi kwemingcele ephephile.

Kodwa ukulawulwa kwezinga lokushisa kusebenza kanjani ngempela? Yini eyenza uhlelo luzwe ushintsho lokushisa bese luzivumelanisa ngokufanele? Ake sihlole izisekelo zokulawulwa kwezinga lokushisa okuzenzakalelayo, nokuthi le nqubo ebonakala ingabonakali idlala kanjani indima ebalulekile kubuchwepheshe besimanje.

Isimiso Esiyisisekelo Sokusebenza Sokulawula Izinga Lokushisa

Emongweni wayo, ukulawula izinga lokushisa kumayelana nokulinganisa izinga lokushisa lamanje, ukuliqhathanisa nethagethi elibekiwe, bese uthatha isinyathelo sokulungisa noma yimuphi umehluko (obizwa ngokuthi “iphutha”).

Izinyathelo eziyisisekelo yilezi:

1. ①Ukulinganisa – Inzwa (njenge-thermocouple noma i-RTD) ithola izinga lokushisa lamanje.

2. ②Ukuqhathanisa – Isilawuli siqhathanisa inani elilinganisiwe nephuzu elifunwayo.

3. ③Ukulungisa – Uhlelo lusebenzisa imishini yokushisa noma yokupholisa ukuze kuncishiswe iphutha.

4. ④I-Feedback Loop – Kwenziwa izinguquko eziqhubekayo ukuze kulondolozwe izinga lokushisa eliqondiwe.

Izingxenye Zesistimu Yokulawula Izinga Lokushisa

1. Inzwa Yokushisa

   • ①Izinhlobo ezivamile: ama-thermocouple, ama-RTD, ama-thermistors

   • ②Umsebenzi: Linganisa izinga lokushisa langempela lenqubo noma indawo.

2. Isilawuli

   • ①Idivayisi ye-elekthronikhi noma i-logic yesofthiwe esebenzisa ama-algorithms afana ne-PID (Proportional-Integral-Derivative) ukuze kunqunywe ukuthi kudingeka ukulungiswa okungakanani.

   • ②Ikhipha isignali ku-actuator.

3. I-Actuator/Isici Sokulawula

   • ①Amadivayisi afana nama-heater, ama-cooler, ama-valve okulawula izinga lokushisa, noma amafeni alungisa izinga lokushisa.

4. Okokufaka kwe-Setpoint

   • ①Izinga lokushisa eliqondiwe lifakwa ngesandla noma lisethwe ngokuzenzakalelayo ngesofthiwe.

5. Indlela Yokuphendula

   • ①Iqinisekisa ukuthi izilinganiso zesikhathi sangempela ziqondisa izimpendulo zesistimu njalo.

Indlela Ukulawula Izinga Lokushisa le-PID Okusebenza Ngayo

Isilawuli se-PID yi-algorithm esetshenziswa kakhulu ekulawuleni izinga lokushisa kwezimboni ngenxa yokunemba kwayo kanye nokusabela kwayo.

• ①Okulinganayo: Ilungisa umphumela ngokusekelwe kusayizi wephutha.

• ②Okuhlanganisiwe: Kususa amaphutha asele ngokubala inani lamaphutha adlule.

• ③I-derivative: Ibikezela amaphutha esikhathi esizayo ngokusekelwe esilinganisweni soshintsho.

Izicelo Zezimboni Zokulawula Izinga Lokushisa

1. ①Izinhlelo ze-HVAC – Gcina induduzo yangaphakathi ngokulungisa izinga lokushisa lomoya ngokuzenzakalelayo.

2. ②Ukubumba Ngomjovo – Izinga lokushisa lesikhunta eliqondile lithuthukisa ikhwalithi yomkhiqizo.

3. ③Ukudla Neziphuzo – Gcina ukupheka okuphephile, ukupheka nge-pasteurization, noma amazinga okushisa okugcina.

4. ④Ukucubungula Amakhemikhali – Qinisekisa ukuthi kwenzeka ukusabela ezimweni zokushisa ezifanele.

5. ⑤Izitshalo Zikagesi – Phatha amazinga okushisa e-turbine kanye ne-boiler ukuze kuphephe futhi kusebenze kahle.

6. ⑥Imboni Yamavalvu – Sebenzisa amavalvu okulawula izinga lokushisa ukulawula izinga lokushisa koketshezi emapayipini.

Ukulawula Izinga Lokushisa Elihlakaniphile Neledijithali

Ngokukhula kwe-IoT (i-Intanethi Yezinto) kanye nokukhiqizwa okuhlakaniphile, ukulawulwa kwezinga lokushisa sekuthuthuke kakhulu:

• ①Abalawuli bokushisa bedijithali abanezixhumi zesikrini sokuthinta

• ②Ukuqapha okude ngamapulatifomu asekelwe efwini

• ③Izinhlelo zokuzifundela ezizivumelanisa nezinguquko zemvelo

• ④Izinzwa ezingenantambo kumanethiwekhi okulawula izinga lokushisa asakazwe

Kwenzekani Ngaphandle Kokulawulwa Okufanele Kokushisa

• ①Ukushisa ngokweqile kungalimaza imishini, konakalise izinto, noma kubangele imililo.

• ②Ukushisa ngaphansi komshini kungaholela ezinqubweni ezingaphelele noma ikhwalithi yomkhiqizo ephansi.

• ③Ukungazinzi kwezinga lokushisa kubangela ukuguquguquka kokusebenza, ukumoshwa kwamandla, kanye nezingozi zokuphepha.

Kungakhathaliseki ukuthi iyunithi ye-HVAC, injini yedizili, umugqa wokukhiqiza imithi, noma uhlelo lwe-butterfly valve, ukulawula izinga lokushisa kuqinisekisa ukuthembeka, isikhathi eside, kanye nokusebenza kahle.
