Ama-pressure transmitter ayimishini ebalulekile yokulinganisa emkhakheni wokulawula izinqubo. Ezilungiselelweni zokuzenzakalela zezimboni, onjiniyela ngokuvamile badinga ukuqapha izinkinga "zokudonsa okungu-zero" kuma-pressure transmitter futhi benze ukulinganisa okungu-zero ngokufanele. I-Zero drift ibhekisela esimweni lapho isignali yokuphuma kwethuluzi lokulinganisa iphambuka kancane kancane ephuzwini elingu-zero lomqondo ngokuhamba kwesikhathi noma ngenxa yezinguquko zemvelo lapho okokufaka kungu-zero (akukho buningi obulinganiselwe obusetshenziswayo). Isibonelo, i-pressure transmitter enobubanzi be-0~10 MPa kufanele ikhiphe i-4 mA (yokukhipha okungu-4~20 mA) uma ivezwa kungcindezi yomoya (ukucindezela okungu-zero gauge). I-Zero drift yenzeka lapho ukukhiqizwa kwangempela kuphambuka kancane futhi ngokuqhubekayo kuleli nani. Amaphutha ahlelekile afakwa ngqo athinta ukunemba kokulinganisa kanye nokunemba kokulawula.
Kungani Ama-Pressure Transmitters Ethambekele Ekushintsheni Okungazelelwe?
Isimiso Sokulinganisa:Ama-pressure transmitter ngokuvamile asebenza ngokusekelwe ekuguqukeni kwe-elastic element, okubandakanya ukudluliselwa kwengcindezi ngokomzimba. Le nqubo ingathonywa yizici ezifana nendawo yokufaka kanye nezici eziphakathi nendawo, okuholela ekuphambukeni kwephuzu elingu-zero.
Izidingo Zokusebenzisa:Ama-pressure kanye nama-differential pressure transmitters avame ukudinga ukuzivumelanisa nezikhundla ezahlukene zokufaka kanye nezimo zokulinganisa ekusetshenzisweni kwezimboni. Isibonelo, lapho kulinganiswa izinga loketshezi ethangini elivaliwe, ukujiya kwe-gas phase medium kungavumela i-condensate ukuthi ingene emigqeni ye-impulse kanye nohlangothi olungezansi lwe-transmitter, okubangela amaphutha okulinganisa. Ezimweni ezinjalo, kudingeka ukufuduka okungekuhle okushintsha iphuzu lika-zero le-transmitter ukuze liqale kusuka ekucindezelweni okungekuhle kokungafani ukuze kuhlangatshezwane nezidingo zokusebenza.
Ukuvezwa Kwezinto:Izingxenye zokuzwa ukucindezeleka (njenge-diaphragm yokuhlukanisa) zithintana ngqo ne-medium elinganisiwe. Ukugqwala, ukukala, umthelela wezinhlayiya noma ukunamathela kwe-medium ene-viscous kungashintsha izakhiwo zazo zemishini, okuholela ekushintsheni kwephuzu elingu-zero.
Izici Zemvelo:Ukuqina kwebhawodi okungalingani ngesikhathi sokufakwa, ukucindezeleka komshini okuvela ekukhuleni kokushisa kwepayipi kanye nokufinyela noma ukucindezela okuphezulu okungaguquki (kwama-DP transmitters) kungabangela ukuguquka kwe-diaphragm yokuzwa ukucindezela, okubangela amaphutha aqhubekayo angaguquki. Ukushintshashintsha kwezinga lokushisa kanye nokudlidliza endaweni nakho kungaba nemiphumela eyinkimbinkimbi kakhulu.
Ungabhekana Kanjani Nokudonswa Kwe-Zero Kuma-Pressure Transmitters?
Ukungasheleli kwe-zero kuyinkinga evamile kuma-pressure transmitter futhi kudinga izinyathelo zobuchwepheshe ezahlukahlukene zokunciphisa:
Ukuhlolwa Kwemboni Nokulinganiswa:Yenza ukuhlolwa okujulile kwezinga lokushisa eliphansi kakhulu kanye nokucindezela okungaguquki ngesikhathi sokukhiqiza, ugcine idatha yesinxephezelo kusithumeli ukuze kulungiswe ngesikhathi sangempela.
Ukuthuthukiswa Kwezinto Ezibalulekile Nezinqubo:Faka izinto ezinwebekayo ezinamandla aphezulu okukhathala kanye nokuqina okuhle kwezinga lokushisa (i-Hastelloy, ama-diaphragm e-ceramic, njll.) futhi uthuthukise izinqubo zokwelapha ukushisa ukuze unciphise ukucindezeleka kwangaphakathi.
Ukulungiswa Okuvamile Nokulinganiswa:Misa imijikelezo yokulinganisa ngokusekelwe ezimweni zokusebenza bese wenza ukulinganisa endaweni ngaphansi kwezimo ze-zero.
Ukufakwa Okuthuthukisiwe Nokusetshenziswa:Gwema ukuqinisa kakhulu, sebenzisa amabhulakhethi ukuze uhlukanise ukucindezeleka kwepayipi futhi uvimbele ukuqina okuphakathi noma ukwakheka kwekristalu.
Shanghai Wangyuanungumkhiqizi wemishini yezinsimbi kanye nomhlinzeki onesipiliyoni seminyaka engaphezu kwengu-20. Siqoqe imikhuba eminingi yokufaka isicelo endaweni kanye nobuchwepheshe bokuxazulula izinkinga obusebenzayo, okusenza sikwazi ukunikeza amakhasimende imikhiqizo ezinzile nethembekile kanye nokusekelwa kobuchwepheshe obuchwepheshile nokwesikhathi. Uma unemibuzo mayelana nokukhetha noma ukusetshenziswa kwama-transmitter okucindezela kanye nokushisa, sicela ukhululeke ukuxhumana nathi ukuze uthole izixazululo.
