I-ABB valve positioner V18345-1020121001

Imininingwane yomkhiqizo

1 Incazelo emfushane
I-valve positioner ye-ABB V18345-1020121001 iyi-positioner ekwaziyo ukuxhumana, elungiseka ngogesi efakwe kumshini wokusebenza womoya oqondile noma we-angular stroke. Ibonakala ngomklamo omncane futhi ohlangene, ukwakheka kwe-modular, futhi inokusebenza okuhle kakhulu kwezindleko. Amapharamitha okulawula afana nama-elementi okulawula itheminali anqunywa ngokuzenzakalelayo yisimiseli esihlakaniphile, esilondoloza isikhathi esiningi sokulungisa iphutha futhi sizuze ukulawula okuphelele.
1.1 Ukusebenza kwe-Aerodynamic
Imojula ye-I/P ene-amplifier yomoya yangemuva isetshenziselwa ukulawula i-actuator yomoya. Imojula ye-I/P iguqula isignali kagesi yokuma isuka ku-CPU ibe isignali yomoya ngokulinganayo ngokulungisa i-valve enezindawo ezintathu ezinezindlela ezintathu. Ukulungiswa kwe-pressurization noma ukuwohloka kwe-actuator kuyaqhubeka, ngakho-ke ukulawula okuhle kakhulu kungafinyelelwa. Lapho iphuzu elimisiwe lifinyelelwa, i-valve yendlela-ntathu enezindawo ezintathu ikhiya endaweni emaphakathi ukuze kuncishiswe ukusetshenziswa komoya. Kunesamba semiphumela ehlukene ye-pneumatic emine: ukulingisa okukodwa kanye nokwenza kabili, ngakunye kutholakala kumamodeli "we-fail-safe" kanye "ne-fail-lock".
1.1.1 Umsebenzi weFail-Safe
Uma amandla ecishiwe noma isignali iphukile, i-positioner ikhipha i-decompress engu-1, futhi i-actuator ye-pneumatic ibuyisela isiphethu ukuze sisebenzise i-valve endaweni ephephile echaziwe. Uma kuyi-actuator ebamba kabili, okukhiphayo 2 nakho kuyacindezelwa.
1.1.2 Umsebenzi Wokwehluleka-Ukuvimba
Uma amandla ecishiwe noma isignali iphukile, okukhipha indawo engu-1 (okukhiphayo 2, uma kukhona) kuyakhiywa futhi i-actuator yomoya ibambe i-valve endaweni yayo yamanje. Uma ukunikezwa komoya kuphazamiseka, i-actuator icindezela.

Sithatha ukucabangela okungajwayelekile ekuhlanganiseni izinto zethu ukuze siqinisekise ukuthi zibonakala zisesimweni esimangalisayo. I i-abb valve positioner ihlanganiswe ngokuphephile nezinto zokuzivikela ukuze igweme ukulimala ngesikhathi sokuthutha. Sisebenzisa okuhambisana nokusebenza okuhlelekile okuqinile ukuze sidlulisele izinto zethu emhlabeni wonke, siqinisekisa ukuhanjiswa okufika ngesikhathi nokuphephile.

Xhumana nathi

I-Shaaxi ZYY iyinkampani yezinsimbi eziqeqeshiwe egxile ekuthengisweni kwemikhiqizo ephezulu efana no-Emerson, Rosemount, Yokogawa, E+H, Azbil, Fisher, Honeywell, ABB, Siemens, nokuningi. Njengoba sinesipiliyoni esingaphezu kweminyaka eyishumi njengomphakeli, sinikezela ngezinhlobonhlobo zezinhlobo zemikhiqizo futhi sizibophezele ekunikezeni izixazululo ezichwepheshile kumakhasimende ethu. Ukuze uthole ulwazi olwengeziwe lomkhiqizo nezingcaphuno, sicela usithinte ku lm@zyyinstrument.com. Sibheke ngabomvu ukukusiza nokuba negalelo empumelelweni yamaphrojekthi akho ezimboni.
