Ukulinganisa ngokuchanekileyo nangokuthembekileyo inqanaba lolwelo eitankini, kwiinqanawa nakwizisele kunokuba yimfuneko ebalulekileyo phakathi kommandla wolawulo lwenkqubo yoshishino. Uxinzelelo kunye noxinzelelo oluhlukileyo (i-DP) abathumeli ngamahashe okusebenza kwizicelo ezinjalo, inqanaba lokulinganisa ngokulinganisa uxinzelelo lwe-hydrostatic oluqhutywa ngulwelo.
Xa Ukunyuka Ngokuthe ngqo kusilela
Uxinzelelo oluqhelekileyo okanye isidluliseli se-DP siqhele ukuxhonywa ngokuthe ngqo kwi-port yoqhagamshelo lwenkqubo kunye ne-diaphragm yayo yokuziva inxibelelana ngokuthe ngqo nenkqubo yenkqubo. Ngelixa oku kusebenza kulwelo olungenabungozi njengamanzi acocekileyo, ezinye iimeko zemizimveliso zenza le ndlela ngqo ingasebenzi:
Imidiya yobushushu obuphezulu:Ulwelo lwenkqubo eshushu kakhulu lunokodlula ubushushu obukhuselekileyo bokusebenza komatshini wombane kunye nenzwa. Ubushushu bunokubangela ukukhukuliseka komlinganiselo, konakalise izinto zangaphakathi kwaye zomise ulwelo lokuzalisa ngaphakathi.
Viscous, Slurry, okanye Crystallizing Fluids:Izinto ezifana neoyile ekrwada enzima, ipulp, isiraphu, okanye iikhemikhali ezikhazimlayo xa zizipholisa zinokuvala imigca yempembelelo okanye ibhore encinci ekhokelela ekuboneni idiaphragm. Oku kukhokelela kwimilinganiselo edangeleyo okanye evalwe ngokupheleleyo.
Imidiya eNdlozayo okanye eAbrasive:I-Acids, caustics, kunye ne-slurries enamasuntswana abrasive inokukhawuleza okanye itshabalalise i-diaphragm ethambileyo ye-diaphragm ye-transmitter, ibangele ukusilela kwesixhobo kunye nokuvuza okunokwenzeka kwenkqubo.
Ucoceko/Ucoceko lwezicelo:Kwimizi-mveliso yokutya, isiselo, kunye namayeza, iinkqubo zifuna ukucocwa rhoqo kwindawo okanye ukuvala inzala. Iitransmitha kufuneka ziyilwe ngaphandle kwemilenze efileyo okanye imingxuma apho ibhaktheriya inokukhula khona, nto leyo eyenza ukuba iiyunithi eziqhelekileyo zokunyuka ngokuthe ngqo zingahambelani.
Inkqubo yePulsation okanye iVibration:Kwizicelo ezine-pulsation ebalulekileyo okanye i-vibration yomatshini, ukunyuka kwe-transmitter ngokuthe ngqo kwinqanawa kunokudlulisa le mikhosi kwi-sensor ebucayi, okubangelwa ingxolo, ukufundwa okungathembekiyo kunye nokukhathala okunokwenzeka komatshini.
Ukwazisa ngeSistim yeSitywina seDiphragm ekude
I-remote diaphragm seal (ekwaziwa ngokuba yikhemikhali seal okanye igauge guard) yinkqubo eyilelwe ukukhusela umthumeli kwezi meko zinobutshaba. Isebenza njengesithintelo esomeleleyo, esahlukileyo esibandakanya izinto ezintathu eziphambili:
Itywina i-diaphragm:I-flexible, i-membrane enganyangekiyo kwi-corrosion (ehlala yenziwe kwi-SS316, i-Hastelloy, i-Tantalum okanye i-PTFE-coated materials) edibana ngokuthe ngqo kunye nenkqubo yolwelo ngokusebenzisa i-flange okanye i-clamp uxhumano. I-diaphragm iyaphambuka ekuphenduleni uxinzelelo lwenkqubo.
Umbhobho weCapillary:I-capillary evaliweyo egcwele isistim esizinzile, esingenakulinganiswa sokuzalisa ulwelo (njengeoli ye-silicone kunye ne-glycerin). Umbhobho udibanisa i-diaphragm seal kwi-transmitter's sensing diaphragm.
IsiThuthi:Uxinzelelo okanye i-DP transmitter ngokwayo, ngoku ihlukanisiwe kwinkqubo yenkqubo ekude
Umgaqo wokusebenza usekelwe kuMthetho kaPascal wokuhanjiswa koxinzelelo lwamanzi. Uxinzelelo lwenkqubo lusebenza kwi-diaphragm yetywina ekude, ibangela ukuba ijike. Oku kuphambuka kucinezela ulwelo oluzalisekileyo ngaphakathi kwenkqubo ye-capillary ethi emva koko idlulisele olu xinzelelo nge-hydraulically ngetyhubhu ye-capillary ukuya kwi-diaphragm ye-transmitter's sensing. Ngaloo ndlela ilinganisa uxinzelelo ngokuchanekileyo ngaphandle kokudibana nemeko yenkqubo enzima.
Izinto eziluncedo ezingundoqo kunye neeNzuzo eziCwangcisiweyo
Ukuphunyezwa kwenkqubo yokutywina ekude kunika intaphane yeenzuzo eziguqulela ngokuthe ngqo ekuphuculeni ukusebenza kakuhle, ukhuseleko, kunye nokonga iindleko.
Ukukhuselwa kweSixhobo esingenakulinganiswa kunye nobomi obude:
Isebenza njengesithintelo, itywina elikude lithatha uxanduva olupheleleyo lweemeko zenkqubo kwaye i-transmitter ikhuselwe kumaqondo obushushu agqithisileyo, ukubola, ukubetha kunye nokuvala. Yandisa kakhulu ubomi benkonzo yesithutha, ukunciphisa ukuphindaphindeka kokutshintshwa kunye neendleko zizonke zobunini.
Ukuchaneka koMlinganiselo kunye nokuthembeka:
Kwiimeko zokunyuka ngokuthe ngqo, imigca yempembelelo evalekileyo ingumthombo omkhulu wempazamo. Amatywina akude asusa isidingo semigca emide yempembelelo enokuba yindawo yokusilela. Inkqubo ibonelela ngokuthe ngqo, ikhonkco ye-hydraulic ecocekileyo kwinkqubo, iqinisekisa ukufundwa okuphendulayo kunye nokuchanekileyo, nangona i-viscous okanye i-slurry-type fluid.
NONE
Izitywina ezikude zinokukhethwa ngezinto ezikhethekileyo kwaye zizalise ulwelo olulinganiswe ngamaqondo aphezulu kakhulu okanye ama-cryogenic. I-transmitter inokunyuswa kumgama okhuselekileyo ukusuka kumthombo wobushushu, ukuqinisekisa ukuba i-electronics yayo isebenza ngaphakathi koluhlu lobushushu obuchaziweyo. Oku kubalulekile kwizicelo ezinjengeenqanawa ze-reactor, amagubu ebhoyila, okanye iitanki zokugcina i-cryogenic.
ULondolozo oluLula kunye nokuNcitshiswa kwexesha lokuSebenza:
Xa uxhulumaniso lwenkqubo lufuna ukulungiswa, i-transmitter ene-remote seal inokuhlala yodwa kwaye isuswe ngaphandle kokukhupha inqanawa yonke. Ngaphaya koko, ukuba isitywina ngokwaso sonakaliswa, sinokutshintshwa ngokuzimeleyo kwi-transmitter, enokuba yindleko ephantsi kakhulu kwaye ilungiswe ngokukhawuleza.
Ukuguquguquka kuFakelo:
I-tube ye-capillary ivumela ukuba i-transmitter ifakwe kwindawo efanelekileyo kakhulu kwaye ifikeleleke-kude neendawo eziphezulu ze-vibration, iindawo ezinzima ukufikelela kuzo phezulu kwetanki, okanye iindawo ezivaliweyo. Oku kwenza kube lula ukufakela, ulungelelwaniso, kunye neetshekhi zokulondolozwa kwesiqhelo.
Ukuqinisekisa iNkqubo yococeko kunye noGutyulo:
Kwimizi-mveliso yococeko, i-diaphragm seals egungxulwayo ibonelela ngomphezulu ogudileyo, ongenamingxuma ekulula ukuwucoca kunye nokubulala iintsholongwane, ukuthintela ukungcoliseka kwebhaktiriya.
Isitywina se-diaphragm esikude sisisombululo esicwangcisiweyo sokulinganisa inqanaba elithembekileyo nelichanekileyo kwezinye iindawo eziyimfuneko kakhulu kwimizi-mveliso. Ngokwenza umqobo okhuselayo, uvumela uxinzelelo kunye nokwahlukana koxinzelelo olugqithisayo ukuba benze imisebenzi yabo ngokukhuselekileyo nangempumelelo, kude kude ne-corrosion, i-clogging okanye iinyani ezigqithisileyo zenkqubo. eShanghaiWangyuanyinkampani yokwenza itekhnoloji ephezulu egxile kwimveliso kunye nenkonzo yesixhobo somlinganiselo woxinzelelo kunye namava angaphezu kwama-20 eminyaka. Ukuba unayo naziphi na iimfuno okanye imibuzo malungaii-remote diaphragm seal transmitters, nceda ungathandabuzi ukuqhagamshelana nathi.
