\u00a0 \u00a0 \u00a0\u00a0I mange proceskontrol systemer, vi har brug for at opn\u00e5 en meget pr\u00e6cis og ensartet kontrol af flow af v\u00e6sker og gasser ved hj\u00e6lp af automatiserede kontrolsystemer (PLC\/DCS). P\u00e5 grund af den h\u00f8je pr\u00e6cisionskrav, n\u00e5r s\u00e5danne systemer opn\u00e5 et lukket loop styring, kontrol ventil som regel behov for at v\u00e6re konstant og pr\u00e6cist kontrolleret.<\/span>Lille forskydning<\/span>justere.<\/span><\/p>

\u00a0 \u00a0 \u00a0 I dette tilf\u00e6lde\uff0c<\/span>Reguleringsventilen er kernen i proces kontrol. I en variabel flow system, str\u00f8mmen af en v\u00e6ske eller gas, der er \u00e6ndret i henhold til variabler som flow, tryk og temperatur. N\u00e5r du konfigurerer aktuator for kontrol ventil, vi er n\u00f8dt til at v\u00e6lge en process control actuator. De vigtigste egenskaber ved denne type aktuator er en l\u00f8bende tilpasning, h\u00f8j pr\u00e6cision\/h\u00f8j konsistens (lille gentagelse fejl, sm\u00e5 vende tilbage forskel) og hurtig respons.<\/span>De tre ovenn\u00e6vnte karakteristika for process control actuator kan reducere variation af process control, som har en positiv effekt p\u00e5 at sikre sammenh\u00e6ngen i produktionen og forbedre kvaliteten.<\/span><\/p>

\u00a0 \u00a0 \u00a0 Processen betjeningsudstyr er almindeligt anvendt i den kemiske industri, minedrift -, medicinal -, olie -, naturgas -, industriel forbr\u00e6nding ogMad og drikke felt<\/span>\u3002<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

H\u00f8j pr\u00e6cision og h\u00f8j konsistens<\/span><\/strong><\/p>

\u00a0 \u00a0 \u00a0\u00a0Et vigtigt element i processen betjeningsudstyr er deres meget n\u00f8jagtig og konsistent positionering ydeevne.<\/span>I en lukket proces kontrol system, variation i processen faktorer er en vigtig faktor, der for\u00e5rsager afvigelser i kontrol loop. Jo h\u00f8jere n\u00f8jagtighed og bedre konsistens, at den st\u00f8rre grad af kontrol, der ud\u00f8ves p\u00e5 processen, og jo mere det kan sikre sammenh\u00e6ng i den endelige m\u00e5ls\u00e6tning output. Et typisk eksempel er industriel forbr\u00e6nding, det centrale m\u00e5l er at forbedre forbr\u00e6ndingen effektivitet og sikre sammenh\u00e6ng i termisk energi. For industriel forbr\u00e6nding, n\u00e5r aktuatoren styrer str\u00f8mmen og forholdet mellem br\u00e6ndstof og luft, for at sikre fuldst\u00e6ndig effektiv forbr\u00e6nding, kontrol af gas, skal v\u00e6re pr\u00e6cise og konsekvente. P\u00e5 denne m\u00e5de fuldst\u00e6ndig forbr\u00e6nding kan garanteres og h\u00f8jere termisk virkningsgrad kan opn\u00e5s. P\u00e5 samme tid, det reducerer br\u00e6ndstof affald, reducerer udst\u00f8dning og opfylder krav for milj\u00f8beskyttelse.<\/span><\/p>

L\u00f8bende justering<\/strong><\/p>

\u00a0 \u00a0 \u00a0 En anden vigtig del af processen betjeningsudstyr er deres l\u00f8bende justering af ydeevne. Mange industrier og applikationer kr\u00e6ver processen betjeningsudstyr p\u00e5 grund af behovet for l\u00f8bende justering. S\u00e5danne flow control l\u00f8sninger b\u00f8r have evnen til l\u00f8bende at justere, og kan t\u00e5le de h\u00f8je krav til langsigtet drift uden at ofre pr\u00e6cision og konsistens. De specifikke krav til proces betjeningsudstyr er at opn\u00e5 en vedvarende effekt-sats p\u00e5 100% og har en lang levetid under h\u00f8j-frekvens justering. I mad og drikke produktion, med henblik p\u00e5 at kontrollere forholdet af r\u00e5varer med h\u00f8j pr\u00e6cision, proces betjeningsudstyr med h\u00f8j pr\u00e6cision, h\u00f8j konsistens, og l\u00f8bende justering er p\u00e5kr\u00e6vet.<\/p>

Hurtig respons<\/strong><\/p>

\u00a0 \u00a0 \u00a0 Den proces control actuator b\u00f8r ogs\u00e5 have karakter af hurtig respons. I en flow-kontrol-system med luft eller h\u00f8jtryks v\u00e6ske som medium, dynamikken i hele closed-loop-processen er meget h\u00f8j p\u00e5 grund af de hurtige \u00e6ndringer i v\u00e6sentlige parametre i kontrol proces. Derfor, i denne ans\u00f8gning, er det n\u00f8dvendigt at matche en process control actuator med kendetegnene for hurtig respons. Det grundl\u00e6ggende krav er, at svartiden p\u00e5 aktuatoren er 1\/10 eller mindre af det dynamiske respons tid af hele en lukket proces.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
