Ukulinganisa ngokunembile nangokuthembekile izinga loketshezi ematangini, emikhunjini nasezindlini zokugcina izinto kungaba yimfuneko eyisisekelo phakathi kwesizinda sokulawula izinqubo zezimboni. Ama-pressure kanye ne-differential pressure (DP) transmitters yiwona asebenza kakhulu kulezi zinhlelo zokusebenza, enquma izinga ngokulinganisa ingcindezi ye-hydrostatic ekhishwa uketshezi.
Uma Ukufakwa Okuqondile Kuhluleka
I-pressure ejwayelekile noma i-DP transmitter ivame ukufakwa ngqo echwebeni lokuxhuma izinqubo kanye ne-diaphragm yayo yokuzwa ixhumana ngqo ne-process medium. Nakuba lokhu kusebenza kahle eziketshezini ezingenabungozi njengamanzi ahlanzekile, ezinye izimo zezimboni zenza le ndlela eqondile ingasebenzi:
Imidiya Eshisa Kakhulu:Uketshezi lwenqubo olushisa kakhulu lungadlula izinga lokushisa lokusebenza eliphephile lama-elekthronikhi kanye nenzwa yomthumeli. Ukushisa kungabangela ukukhukhuleka kokulinganisa, kulimaze izingxenye zangaphakathi futhi komise uketshezi olugcwalisiwe ngaphakathi.
Uketshezi Oluqinile, Oluthambile, Noma Olucwebezelayo:Izinto ezifana namafutha aluhlaza asindayo, i-pulp, isiraphu, noma amakhemikhali acwebezelayo lapho ephola zingavimba imigqa ye-impulse noma imbobo encane eholela ku-diaphragm yokuzwa. Lokhu kuholela ekulinganisweni okuhamba kancane noma okuvalekile ngokuphelele.
Izinto Ezonakalisayo Noma Ezilimazayo:Ama-asidi, ama-caustics, kanye nama-slurry anezinhlayiya ezihudulayo angagqwala noma agugule ngokushesha i-diaphragm yokuzwa ethambile yomthumeli, okubangela ukwehluleka kwethuluzi kanye nokuvuza kwenqubo okungenzeka.
Izicelo Zokuhlanzeka/Zokuhlanzeka:Ezimbonini zokudla, iziphuzo, kanye nezokwelapha, izinqubo zidinga ukuhlanzwa njalo endaweni noma ukubulala amagciwane endaweni. Ama-transmitter kumele aklanywe ngaphandle kwemilenze efile noma imifantu lapho amabhaktheriya angakhula khona, okwenza amayunithi ajwayelekile okufaka ngqo angahambisani nemithetho.
Ukushaya Kwenqubo Noma Ukudlidliza:Ezisetshenzisweni ezine-pulsation ebalulekile noma ukudlidliza komshini, ukufaka i-transmitter ngqo emkhunjini kungadlulisela la mandla ku-sensor ezwelayo, okuholela ekufundeni okunomsindo, okungathembekile kanye nokukhathala okungenzeka komshini.
Sethula Uhlelo Lokuvala I-Diaphragm Olukude
I-remote diaphragm seal (eyaziwa nangokuthi i-chemical seal noma i-gauge guard) iyisistimu eyenzelwe ukuvikela umthumeli kulezi zimo ezinonya. Isebenza njengesithiyo esiqinile, esihlukanisayo esakhiwe yizingxenye ezintathu ezibalulekile:
I-Diaphragm Yesivalo:I-membrane eguquguqukayo, engagqwali (evame ukwenziwa ngezinto ezimbozwe nge-SS316, Hastelloy, Tantalum noma i-PTFE) ethintana ngqo noketshezi lwenqubo ngokuxhumeka kwe-flange noma i-clamp. I-diaphragm iyaphambuka ngenxa yokucindezela kwenqubo.
Ipayipi le-Capillary:I-capillary evaliwe egcwele uketshezi lokugcwalisa uhlelo oluzinzile nolungacindezeleki (njenge-silicone oil kanye ne-glycerin). Ithubhu ixhuma uphawu lwe-diaphragm ku-diaphragm yokuzwa yomthumeli.
Umthumeli:Ingcindezi noma i-DP transmitter uqobo, manje esehlukaniswe ne-process medium kude
Isimiso sokusebenza sisekelwe kuMthetho kaPascal wokudluliselwa kwengcindezi yoketshezi. Ingcindezi yenqubo isebenza ku-diaphragm yesivalo esikude, okwenza iphambuke. Lokhu kuphambuka kucindezela uketshezi olugcwalisiwe ngaphakathi kohlelo lwe-capillary olube seludlulisela lo mfutho ngamandla kagesi ngepayipi le-capillary liye ku-diaphragm yokuzwa yomthumeli. Ngakho-ke ilinganisa ingcindezi ngokunembile ngaphandle kokuthinta isimo senqubo esiyinkinga.
Izinzuzo Eziyinhloko kanye Nezinzuzo Ezibalulekile
Ukuqaliswa kohlelo lokuvala olukude kunikeza izinzuzo eziningi ezihumushela ngqo ekusebenzeni kahle, ukuphepha, kanye nokonga izindleko.
Ukuvikelwa Kwezinsimbi Okungenakuqhathaniswa Nokuphila Isikhathi Eside:
Njengoba isebenza njengesithiyo, isivalo esikude sithwala umthwalo ophelele wezimo zenqubo futhi isithumeli sivikelwe emazingeni okushisa aphezulu, ukugqwala, ukuklwebheka kanye nokuvaleka. Kwandisa kakhulu impilo yesevisi yesithumeli, kunciphisa imvamisa yokushintshwa kanye nezindleko eziphelele zobunikazi.
Ukunemba Nokuthembeka Kokulinganisa Okuthuthukisiwe:
Ezimweni zokufaka ngqo, imigqa ye-impulse evalekile iwumthombo omkhulu wephutha. Izivalo ezikude zisusa isidingo semigqa ye-impulse emide okuyiphuzu elingaba khona lokwehluleka. Uhlelo luhlinzeka ngesixhumanisi esiqondile nesihlanzekile se-hydraulic kule nqubo, siqinisekisa ukufundwa okuphendulayo nokunembile, ngisho nangoketshezi oluqinile noma olufana ne-slurry.
Ukulinganisa Kokuvula Ezimweni Zokushisa Eziphezulu:
Izivalo ezikude zingakhethwa ngezinto ezikhethekile kanye noketshezi lokugcwalisa olulinganiselwe amazinga okushisa aphezulu kakhulu noma angenawo umoya. I-transmitter ingafakwa kude nomthombo wokushisa, ukuqinisekisa ukuthi i-elekthronikhi yayo isebenza ngaphakathi kwebanga lokushisa elibekiwe. Lokhu kubalulekile ezisetshenziswayo njengemikhumbi ye-reactor, ama-drum e-boiler, noma amathangi okugcina amanzi angenawo umoya.
Ukulungiswa Okulula kanye Nesikhathi Sokungasebenzi Esincishisiwe:
Uma uxhumano lwenqubo ludinga ukulungiswa, i-transmitter ene-remote seal ingahlukaniswa futhi isuswe ngaphandle kokukhipha amanzi emkhunjini wonke. Ngaphezu kwalokho, uma i-seal yonakala, ingashintshwa ngokuzimela ngaphandle kwe-transmitter, okungaba ukulungiswa okungabizi kakhulu futhi okusheshayo.
Ukuguquguquka kokufakwa:
Ipayipi le-capillary livumela ukuthi i-transmitter ifakwe endaweni elula kakhulu futhi efinyeleleka kalula—kude nezindawo ezidlidliza kakhulu, izindawo okunzima ukufinyelela kuzo phezu kwethangi, noma izikhala ezivalekile. Lokhu kwenza kube lula ukufakwa, ukulinganiswa, kanye nokuhlolwa kokugcinwa okuvamile.
Ukuqinisekisa Ukuhlanzeka Kwenqubo Nokuhlanzeka:
Ezimbonini zokuhlanzeka, izimbozo ze-diaphragm ezifakwe emanzini zinikeza indawo ebushelelezi, engenamifantu okulula ukuyihlanza nokuyibulala amagciwane, okuvimbela ukungcoliswa ngamagciwane.
I-remote diaphragm seal iyisisombululo esihlakaniphile sokulinganisa amazinga okuthembekile nokunembile kwezinye zezindawo zezimboni ezidinga kakhulu. Ngokudala isithiyo esivikelayo, ivumela abathumeli bengcindezi kanye nokucindezela okuhlukile ukuthi benze imisebenzi yabo ngokuphepha nangokuphumelelayo, bekude kakhulu namaqiniso angcolisayo, avalayo noma ashisa kakhulu enqubo.Wangyuaniyinkampani yokukhiqiza ubuchwepheshe obuphezulu egxile ekukhiqizeni nasekuhlinzekeni izinsiza zokulinganisa ingcindezi enolwazi olungaphezu kweminyaka engama-20. Uma unezidingo noma imibuzo mayelanaama-transmitter ophawu lwe-diaphragm akude, sicela ungangabazi ukuxhumana nathi.
