Ukulinganisa ngokuchanekileyo nangokuthembekileyo inqanaba lolwelo kwiitanki, iinqanawa kunye neesilos kunokuba yimfuneko ebalulekileyo phakathi kolawulo lweenkqubo zoshishino. Iitransmitter zoxinzelelo kunye nomahluko (DP) zezona zisebenzayo kwezo zicelo, ziqikelela inqanaba ngokulinganisa uxinzelelo lwe-hydrostatic olukhutshwa lulwelo.
Xa ukuFakelwa ngqo kungaphumeleli
Isixhobo soxinzelelo oluqhelekileyo okanye i-DP transmitter sidla ngokuxhonywa ngqo kwi-process connection port kunye ne-sensing diaphragm yaso idibana ngqo ne-process medium. Nangona oku kusebenza kulwelo olungengobungozi njengamanzi acocekileyo, ezinye iimeko zoshishino zenza le ndlela ingasebenzi:
Imidiya enobushushu obuphezulu:Ulwelo lwenkqubo olushushu kakhulu lunokudlula ubushushu obusebenzayo obukhuselekileyo be-elektroniki kunye ne-sensor yesixhobo sokudlulisa. Ubushushu bunokubangela ukushukuma komlinganiselo, bonakalise izinto zangaphakathi kwaye bomise ulwelo oluzaliswayo ngaphakathi.
Ulwelo oluqinileyo, oluludaka, okanye olunekristali:Izinto ezifana neoyile ekrwada enzima, i-pulp, isiraphu, okanye iikhemikhali eziqina xa zipholile zinokuvala imigca ye-impulse okanye umngxuma omncinci okhokelela kwi-diaphragm yokuva. Oku kukhokelela ekulinganisweni okucothayo okanye okuvalekileyo ngokupheleleyo.
Izinto Ezonakalisayo okanye Ezirhabaxayo:Ii-asidi, ii-caustics, kunye ne-slurry ezinee-abrasive particles zinokutshabalalisa okanye zitshabalalise i-diaphragm ethambileyo yokuva ye-transmitter, nto leyo ebangela ukungasebenzi kakuhle kwesixhobo kunye nokuvuza kweenkqubo.
Izicelo zoCoceko/zoCoceko:Kwimizi-mveliso yokutya, iziselo, kunye namayeza, iinkqubo zifuna ukucocwa rhoqo endaweni okanye ukubulala iintsholongwane endaweni. Iitransmitter kufuneka zenziwe ngaphandle kwemilenze efileyo okanye imingxunya apho iintsholongwane zinokukhula khona, okwenza iiyunithi ezisemgangathweni zokufaka ngqo zingahambelani nemithetho.
Ukushukuma okanye ukungcangcazela kwenkqubo:Kwizicelo ezine-pulsation ebalulekileyo okanye i-mechanical vibration, ukufaka i-transmitter ngqo kwi-vessel kunokudlulisela la mandla kwi-sensor ebucayi, nto leyo ebangela ingxolo, ukungathembeki kunye nokudinwa okunokwenzeka kwe-mechanical.
Ukwazisa iNkqubo yokutywina iDiaphragm ekude
I-remote diaphragm seal (ekwaziwa ngokuba yi-chemical seal okanye i-gauge guard) yinkqubo eyenzelwe ukukhusela i-transmitter kwezi meko zinobutshaba. Isebenza njengomqobo oqinileyo, owahlulayo oquka izinto ezintathu ezibalulekileyo:
I-Diaphragm yeTywina:I-membrane eguquguqukayo, enganyangekiyo kukugqwala (edla ngokwenziwa ngezinto ezigqunywe yi-SS316, i-Hastelloy, i-Tantalum okanye i-PTFE) edibana ngqo nolwelo lwenkqubo ngoqhagamshelo lwe-flange okanye i-clamp. I-diaphragm iyajika xa iphendula kuxinzelelo lwenkqubo.
Umbhobho weCapillary:I-capillary evaliweyo ezaliswe lulwelo oluzinzileyo nolungacinezekiyo lokuzalisa inkqubo (njengeoyile ye-silicone kunye ne-glycerin). Ityhubhu iqhagamshela isitywino se-diaphragm kwi-diaphragm yokuva ye-transmitter.
Umthumeli:Uxinzelelo okanye i-DP transmitter ngokwayo, ngoku yahlulwe kwi-process medium kumgama
Umgaqo wokusebenza usekelwe kuMthetho kaPascal wokudluliselwa koxinzelelo lolwelo. Uxinzelelo lwenkqubo lusebenza kwi-diaphragm yesitywina esikude, nto leyo ebangela ukuba iphambuke. Oku kujika kucinezela ulwelo oluzaliswayo ngaphakathi kwenkqubo ye-capillary oluthi emva koko ludlulisele olu xinzelelo nge-hydraulic ngetyhubhu ye-capillary ukuya kwi-diaphragm yokuva yomthumeli. Ngaloo ndlela ilinganisa uxinzelelo ngokuchanekileyo ngaphandle kokudibana nemeko yenkqubo enzima.
Iingenelo eziphambili kunye neenzuzo zobuchule
Ukusetyenziswa kwenkqubo yokutywina ekude kunika iingenelo ezininzi eziguqulela ngokuthe ngqo ekuphuculeni ukusebenza kakuhle, ukhuseleko, kunye nokonga iindleko.
Ukhuseleko lweZixhobo eziNgcono kunye noBomi obude:
Isebenza njengomqobo, isitywina esikude sithwala ubunzima obupheleleyo beemeko zenkqubo kwaye i-transmitter ikhuselekile kumaqondo obushushu aphezulu, ukugqwala, ukukrweleka kunye nokuvaleka. Yandisa kakhulu ubomi benkonzo ye-transmitter, inciphisa ukuphindaphinda kokutshintshwa kunye neendleko zizonke zobunini.
Ukuchaneka Nokuthembeka Kokulinganisa Okuphuculweyo:
Kwiimeko ezithe ngqo, imigca ye-impulse evalekileyo yeyona nto ibangela iimpazamo. Izitywino ezikude zisusa isidingo semigca ye-impulse emide enokuba yindawo enokwenzeka yokusilela. Inkqubo ibonelela ngekhonkco le-hydraulic elithe ngqo nelicocekileyo nenkqubo, ukuqinisekisa ukufundwa okuchanekileyo nokuchanekileyo, nokuba kulwelo oluqinileyo okanye olufana nolwelo.
Uvavanyo Lokuvula Kwiiqondo Zobushushu Ezigqithisileyo:
Izitywini ezikude zingakhethwa ngezixhobo ezikhethekileyo kunye nolwelo oluzaliswayo olulinganiswe kumaqondo obushushu aphezulu kakhulu okanye angenawo ubushushu. I-transmitter ingafakelwa kumgama okhuselekileyo ukusuka kumthombo wobushushu, ukuqinisekisa ukuba i-elektroniki yayo isebenza ngaphakathi komgangatho wayo wobushushu obuchaziweyo. Oku kubalulekile kwizicelo ezifana neebhakede ze-reactor, ii-drum ze-boiler, okanye iitanki zokugcina i-cryogenic.
Ukugcinwa okulula kunye nexesha lokungasebenzi elincitshisiweyo:
Xa uqhagamshelo lwenkqubo lufuna ukulungiswa, i-transmitter ene-remote seal inokuhlala ikhutshiwe kwaye isuswe ngaphandle kokukhupha amanzi kwinqanawa yonke. Ngaphezu koko, ukuba i-seal yonakele, inokutshintshwa ngokuzimeleyo ngaphandle kwe-transmitter, nto leyo enokuba yindlela yokulungisa engabizi kakhulu kwaye ikhawuleze.
Ukuguquguquka kofakelo:
Ityhubhu ye-capillary ivumela ukuba i-transmitter ifakwe kwindawo efanelekileyo nefikelelekayo—kude neendawo ezinokungcangcazela kakhulu, iindawo ezinzima ukufikelela kuzo phezu kwetanki, okanye kwiindawo ezixineneyo. Oku kwenza kube lula ukufakwa, ukulinganiswa, kunye nokuhlolwa kokugcinwa rhoqo.
Ukuqinisekisa ukuCoceka kweNkqubo kunye noCoceko:
Kwimizi-mveliso yococeko, izitywina ze-diaphragm ezifakwe emanzini zibonelela ngomphezulu ogudileyo, ongenamiqolomba okulula ukuwucoca nokuwubulala iintsholongwane, nto leyo ethintela ungcoliseko lweentsholongwane.
I-remote diaphragm seal sisisombululo esicwangcisiweyo sokulinganisa amanqanaba ngendlela ethembekileyo nechanekileyo kwezinye zezona ndawo zinzima kakhulu kwezoshishino. Ngokwenza umqobo okhuselayo, ivumela abathumeli boxinzelelo kunye noxinzelelo olwahlukileyo ukuba benze imisebenzi yabo ngokukhuselekileyo nangokufanelekileyo, kude kakhulu neenyani ezirhabaxa, ezivalekileyo okanye ezishushu kakhulu zenkqubo.Wangyuanyinkampani yokuvelisa ubuchwepheshe obuphezulu egxile kwimveliso kunye nenkonzo yezixhobo zokulinganisa uxinzelelo kunye namava angaphezu kweminyaka engama-20. Ukuba unayo nayiphi na imfuneko okanye imibuzo malungaii-transmitters zesitywina se-diaphragm ezikude, nceda ungathandabuzi ukuqhagamshelana nathi.
