Ibhokisi Lokushintsha Lomkhawulo: Umhlahlandlela Ophelele
Ezinhlelweni zesimanje ezishintshayo zezimboni kanye nokulawula ama-valve, kubalulekile ukuqinisekisa ukugadwa okunembayo kokuma kwe-valve. Akhawulela ibhokisi lokushintshaidlala indima ebalulekile kule nqubo ngokunikeza impendulo ethembekile kubaqhubi kanye nezinhlelo zokulawula. Kungakhathaliseki ukuthi kumapayipi kawoyela negesi, ezimbonini zokuhlanza amanzi, noma izimboni zamakhemikhali, idivayisi iqinisekisa ukuthi ukusebenza kwamavalvu kuphephile, kunembile, futhi kuyalandeleka.
Lesi sihloko sinikeza incazelo enemininingwane yokuthi liyini ibhokisi lokushintsha umkhawulo, ukuthi lisebenza kanjani, izingxenye zalo eziyinhloko, izinhlobo ezahlukene, kanye nezinhlelo zokusebenza kuzo zonke izimboni ezihlukahlukene. Ekugcineni, uzoba nokuqonda okucacile kokuthi kungani le divayisi ibalulekile ekulawuleni inqubo.
Liyini Ibhokisi Lokushintsha Umkhawulo?
Ibhokisi lokushintsha umkhawulo liyidivaysi ehlangene efakwe phezu kwama-actuator noma ama-valve. Umsebenzi wayo oyinhloko ukukhombisa ukuthi i-valve isendaweni evulekile noma evaliwe. Iguqula ukunyakaza komshini kwesiqu se-valve noma i-actuator shaft ibe isignali kagesi engathunyelwa kusistimu yokulawula esakazwayo (DCS), isilawuli se-programmable logic (PLC), noma izinkomba ezibonakalayo zabaqhubi bezitshalo.
Ngamagama alula, isebenza "njengamehlo" wesistimu ye-valve. Ngenkathi i-actuator ihambisa i-valve, ibhokisi lokushintsha umkhawulo liqinisekisa ukuthi opharetha bazi kahle ukuthi i-valve ibekwe kuphi.
Izinjongo Eziyinhloko
- I-Valve Position Impendulo- Inikeza amasignali kagesi ukulawula amakamelo mayelana nokuthi i-valve ivuliwe noma ivaliwe.
- Isiqiniseko Sokuphepha- Ivimbela ukusebenza okungalungile okungadala ukuvuza, ukuchitheka, noma izingozi.
- Ukuhlanganisa okuzenzakalelayo- Inika amandla ukuxhumana nama-PLC kanye nezinhlelo ze-SCADA zokulawula inqubo ezenzakalelayo.
- Isibonakaliso Esibonakalayo- Amabhokisi amaningi ahlanganisa izinkomba zemishini (isb, imicibisholo ebomvu/eluhlaza noma amadome) ukuze kuqashwe kalula endaweni.
Lisebenza Kanjani Ibhokisi Lokushintsha Umkhawulo?
Umgomo wokusebenza webhokisi lokushintsha umkhawulo uqondile, nokho ukwethembeka kwawo kuyenza ibaluleke kakhulu.
- Mechanical Movement– Uma i-actuator ivula noma ivala i-valve, i-shaft noma isiqu siyazungeza noma sinyakaze ngokulandelana.
- I-Cam Mechanism- Ngaphakathi kwebhokisi lokushintsha umkhawulo, ikhamera efakwe ku-shaft ijikeleza ngokufanele.
- Shintsha Ukwenza Kusebenze- Ikhamera isebenzisana namaswishi amancane, izinzwa eziseduze, noma izinzwa kazibuthe ngaphakathi kwebhokisi.
- Ukudluliselwa Kwesiginali– Uma sezicushiwe, lezi zinguquko zithumela isignali kagesi ukukhombisa indawo yevalvu (izifunda ezivulekile/ezivaliwe noma eziphakathi).
- Impendulo Kusistimu Yokulawula- Isiginali idluliselwa kumaphaneli okulawula, i-SCADA, noma izibonisi zasendaweni.
Isibonelo Esenziwe Lula
- Ivalvu ivuleke ngokugcwele → Ikhamera icupha iswishi "evulekile" → Isignali eluhlaza ithunyelwe.
- Ivalvu ivalwe ngokugcwele → Ikhamera icupha iswishi “evaliwe” → Isignali ebomvu ithunyelwe.
- Ivaluvu ekuguqukeni → Ayikho isignali eqondile, noma kumamodeli athuthukile, impendulo ye-analogi ebonisa indawo ngqo.
