I-Molybdenum induku yokushisa kagesiisilawuli samandlaiyithuluzi elisetshenziselwa ukulawula ukushisisa kukagesi kwezinduku ze-molybdenum.I-Molybdenum rod iyisici sokushisa kagesi esisetshenziswa kakhulu, esenziwe nge-molybdenum, sinephuzu eliphezulu lokuncibilika kanye nokumelana nokushisa okuphezulu, ngakho-ke isetshenziswa kabanzi emkhakheni wokushisa okuphezulu.Imisebenzi eyinhloko yenduku ye-molybdenumisilawuli sokushisa kagesihlanganisa izici ezilandelayo: 1. Ukulawula izinga lokushisa: Isilawuli sokushisa sikagesi se-molybdenum rod singakwazi ukuqapha izinga lokushisa le-molybdenum rod ngesikhathi sangempela ngesici senzwa yokushisa (njenge-thermocouple noma ukumelana nokushisa), futhi silungise futhi silawule ngokuvumelana nezinga lokushisa elimisiwe. ububanzi bokugcina induku ye-molybdenum isebenza ezingeni lokushisa elishiwo ngaphakathi kobubanzi.2. Ukulungiswa kwamandla okushisa: Isilawuli sokushisa kagesi se-molybdenum rod singalungisa amandla okushisa ngokuvumelana nesidingo, futhi silawule umphumela wokushisa we-molybdenum rod ngokulawula okwamanje noma i-voltage.3. Ukuvikelwa kwamanje: Isilawuli sokushisa kagesi se-molybdenum rod singaqapha ukusebenza kwamanje kwenduku ye-molybdenum.Uma i-current idlula inani elibekiwe, kuzothathwa izinyathelo zokuvikela ezihambisanayo, njengokunciphisa amandla noma ukunqamula ukunikezwa kwamandla, ukugwema izingozi zokuphepha ezibangelwa ingozi enkulu yamanje kanye nokulimala kwemishini.4. Isibonisi ne-alamu: Isilawuli sokushisa kagesi se-molybdenum rod ngokuvamile sifakwe isikrini sokubonisa, esingabonisa izinga lokushisa le-molybdenum rod, amandla okushisa kanye neminye imingcele.Ngesikhathi esifanayo, lapho izinga lokushisa lidlula ibanga elimisiwe noma ezinye izimo ezingavamile zenzeka, kuzokhishwa i-alamu ukuze kukhumbuze opharetha ukuthi athathe izinyathelo ezifika ngesikhathi.Kafushane, isilawuli sokushisa sikagesi se-molybdenum rod singakwazi ukubona ukulawula okunembile kwezinga lokushisa namandla okushisa entonga ye-molybdenum, futhi siqinisekise ukushisisa okuzinzile kwenduku ye-molybdenum phakathi kwebanga eliphephile.Ilungele izinhlelo zokusebenza ezihlukahlukene zezimboni nezokuhlola ezidinga ukushisa okuphezulu.
Ukulawula induku ye-molybdenum isilawuli sokushisa kagesingokusebenzisa i-4-20mA, kuyadingeka ukusebenzisa i-4-20mA transmitter ukuguqula isignali yokulawula ibe isignali yamanje ehambisanayo.Izinyathelo eziqondile zimi kanje: 1. Lungisa uhlelo lokulawula: Okokuqala, isistimu yokulawula idinga ukulungiswa ukuze ububanzi besignali yokufaka ye-4-20mA ihambisane nobubanzi bokulawula obudingekayo.Isibonelo, uma ufuna ukulawula izinga lokushisa ebangeni lika-0-100°C, ungasebenzisa u-4mA ku-0°C no-20mA ku-100°C.2. Faka i-4-20mA transmitter: Faka i-4-20mA transmitter endaweni yokufaka yokulawula yesilawuli sokushisa sikagesi se-molybdenum rod.Umsebenzi walesi sithumeli ukuguqula isignali yokulawula (isibonelo, ukuphuma kwesignali ye-analog nge-PLC noma isilawuli se-PID) ibe isignali ehambisanayo ye-4-20mA yamanje.3. Xhuma izintambo zamandla nesignali: Xhuma isidlulisi kumandla futhi ulawule imithombo yamasignali.Ngokuvamile, isidluliseli sidinga ukuxhuma amandla (ngokuvamile i-DC24V) kutheminali yayo yamandla, bese sixhuma isignali yokuphumayo engu-4-20mA kutheminali yokufaka yokulawula yesilawuli sokushisisa ugesi se-molybdenum.4. Lungisa ububanzi bokuphumayo: Ngokuvumelana nezidingo zangempela, kungase kudingeke ukulungisa uhla lokuphumayo lwe-4-20mA transmitter.Amanye ama-transmitter anemisebenzi elungisekayo enguziro neye-span, engalungiswa ngokufanele njengoba kudingeka.5. Yenza ukulawula: Uma izinyathelo ezingenhla seziqediwe, isignali yokulawula ehambisanayo ingathunyelwa ngomthombo wesiginali yokulawula njenge-PLC noma isilawuli se-PID.I-transmitter izoguqula lesi siginali ibe isignali yamanje engu-4-20mA futhi iyithumele kusilawuli sokushisa sikagesi se-molybdenum rod.Khona-ke, isilawuli sokushisa kagesi se-molybdenum sizolawula amandla okushisa nokushisa kwenduku ye-molybdenum ngokusho kwesignali eyamukelwe.Kumele kuqashelwe ukuthi izinyathelo ezithile zokusebenza zingase zihluke, ngakho-ke kunconywa ukuthi ubheke imanuwali yokusebenza yesilawuli sokushisa kagesi se-molybdenum rod kanye ne-4-20mA transmitter esetshenziselwa ukuqinisekisa uxhumano olufanele nokucushwa.
