Njengamadivayisi okuzwa ayinhloko ezinhlelweni zokulawula ukuzenzekela kwezimboni,ama-pressure transmitterivame ukubhekana nezimo zokulinganisa ezinzima ezimbonini zenqubo zesimanje ezifana ne-petroleum, amakhemikhali, amandla, ukudla, kanye nemithi. I-diaphragm yayo yenzwa akuyona nje into yokuzwa yokudlulisa ingcindezi kodwa futhi iwumugqa wokuqala wokuzivikela, ihlukanisa indlela yenqubo kusuka kuketshezi lokugcwalisa lwangaphakathi futhi ivimbele umonakalo wenzwa. Isayensi yezinto ezibonakalayo kanye nokwakheka kwesakhiwo se-diaphragm kuyisihluthulelo sokubhekana nezimo zokusebenza eziyinkimbinkimbi. Ukukhetha okungalungile kungaholela ezinkingeni ezisukela ekukhukhuleni kokulinganisa kuya ekubhobokeni kwe-diaphragm, ukuklebhuka kwemishini, ngisho nezingozi zokuphepha. Ukukhetha kahle umthumeli wokucindezela kuyisinyathelo esibalulekile ekuqinisekiseni ukusebenza okuzinzile, okuthembekile nokungabizi kwesistimu yonke yokulinganisa.
Izici Zamakhemikhali Ukukhetha I-Drive Diaphragm
Ukuhambisana kwamakhemikhali kwezinto ze-diaphragm kuyisidingo esiyinhloko sokukhethwa kwemodeli. Izinhlobo ezahlukene ze-media zinezindlela zokugqwala ezihlukene ezintweni zensimbi, ezidinga ukuhlaziywa ngokusekelwe ekwakhekeni kwamakhemikhali azo kanye nezakhiwo zokugqwala. Kuma-media agqwala kakhulu njenge-acids enamandla nama-alkali, insimbi engagqwali engu-316L evamile ingase ingahlangabezani nezidingo zokuzinza zesikhathi eside. Isibonelo, ezindaweni eziqukethe i-sulfuric acid noma i-phosphoric acid ekushiseni kwegumbi, i-Hastelloy C-276 iba yisinqumo esifanele ngenxa yokumelana kwayo okuhle kakhulu nokugqwala kusukela ekunciphiseni okuphakathi. I-diaphragm ye-Tantalum ibonisa ukungangeni kwamakhemikhali cishe okuphelele uma ivezwa kuma-medium aqinile kakhulu njenge-nitric acid, kodwa izindleko eziphakeme zivame ukukhawulela ukusetshenziswa kwayo emicimbini ekhethekile njengamakhemikhali amahle noma ukukhiqizwa kwamakhemikhali okuhlanzekile kakhulu. Kubunjiniyela basolwandle noma ezindaweni eziqukethe ama-chloride, ama-ion e-chloride angabangela kalula ukugqwala kwe-pitting ensimbini engagqwali evamile. Lapha, i-Monel yamukelwa kabanzi ngenxa yamandla ayo amahle kakhulu okudlulisa amanzi olwandle kanye nesisombululo se-brine.
Isimo Esiphakathi Nesiphakathi Silawula Ukwakheka Kwe-Diaphragm
Uhlobo olubonakalayo lwe-medium (isb., i-viscosity, okuqukethwe okuqinile) luthinta ngqo ukukhethwa kwesakhiwo se-diaphragm. Kwabaphakathi abaqinile kakhulu noma abathambekele ekukhanyeni, izakhiwo ezivamile ezine-inlet encane yokucindezela zisengozini enkulu yokuvaleka, okuholela ekwehlulekeni kokudluliselwa kwengcindezi.Umklamo we-diaphragm oyisicabaingasetshenziswa ezimweni ezinjalo esusa imbobo yokucindezela futhi ivumele i-diaphragm ukuthi ixhumane ngqo ne-medium. Isakhiwo se-flush mount asikwazi nje ukuvimbela ukuvaleka kodwa futhi sihlangabezane nesidingo sokuklama okuhlanzekile embonini yokudla nemithi ngenxa yokuntuleka kwayo kwezindawo eziqinile. Uma i-medium iqukethe izinhlayiya eziqinile, i-diaphragm ibhekene nengozi enkulu yokuguguleka. Ama-diaphragm e-ceramic angamelana ngempumelelo nokuguguleka kwezinhlayiya ngenxa yobunzima bawo obukhulu kakhulu kanye nokumelana nokuguguleka. Ezinye izinhlelo zokusebenza eziqine kakhulu zingasebenzisa nama-diaphragm e-flush aqinile ukuze kwandiswe kakhulu impilo yesevisi yemishini ngaphansi kwezimo ezinzima.
Izixazululo Zokuzivumelanisa Nezimo Ezimbi Zokusebenza
Ezindaweni zokushisa okuphezulu kwenqubo, ukusebenza kwe-thermodynamic kwenhlangano yenzwa kubalulekile. Uketshezi lokugcwalisa kufanele lube uwoyela we-silicone okushisa okuphezulu ukuvimbela ukuhwamuka kwe-medium edlulisa ingcindezi, kuhlanganisweizivalo ze-capillary ezikude, izinto zokupholisanoma ezinye izindlela zokushabalalisa ukushisa ukuvikela izingxenye ze-elekthronikhi ekulimaleni kokushisa okuphezulu. Izicelo ezibandakanya okuqukethwe okukhulu kwe-hydrogen zidinga ama-diaphragm ambozwe ngegolide ukuvimbela ukuqhekeka kwe-hydrogen. Ezimweni lapho ukucindezela okuphakathi kushintshashintsha kakhulu (isb., lapho impompi yokucindezela iseduze nendawo yokuphuma kwepompo), ukufaka i-pulsation damper kufanele kucatshangelwe ukunciphisa ukuguquguquka kwesignali.
Izici zezinto ze-Diaphragm
Insimbi Engagqwali 316L: Ama-diaphragm avamile e-SS316L abonisa amandla amahle okusebenza kanye nokumelana nokugqwala. Afaneleka kakhulu ezinhlotsheni eziningi zezimboni ezilinganisa uketshezi namagesi angagqwali kakhulu, anikeza ukuguquguquka okunamandla kanye nokusebenza kahle kwezindleko.
I-Hastelloy C: Ingxubevange esekelwe ku-nickel enokumelana okuhle kakhulu kokubili ama-asidi akhipha i-oxidation kanye nokunciphisa i-asidi. Ukusetshenziswa okuvamile kufaka phakathi izindawo ezine-asidi enamandla ekushiseni okujwayelekile kanye nosawoti okhipha i-oxidation.
I-Monel: Ingxubevange ye-nickel-copper enokumelana okuhle nokugqwala kuma-asidi angewona ama-oxidizing (ikakhulukazi i-hydrofluoric acid) kanye nokumelana okuhle kakhulu emanzini olwandle. Ama-diaphragm e-Monel afanele ukusetshenziswa kolwandle, umusi, usawoti kanye nezindawo eziqukethe inani elincane le-hydrochloric acid.
I-Tantalum: Inezakhiwo zamakhemikhali ezizinzile kakhulu kanye nokumelana nokugqwala okuvelele ngezindleko eziphakeme. Ifanelekela izinqubo ezahlukahlukene zamakhemikhali ezidinga ukumelana nokugqwala okuphezulu, kodwa ayimelani ne-hydrofluoric acid kanye nama-alkali aqinile.
I-Ceramic: Iqukethe ubulukhuni obuphezulu kakhulu, ukumelana nokuguguleka, kanye nokungangeni kwamakhemikhali. Isetshenziswa kuizinzwa zomthamo we-ceramic, ngokuvamile inkulu ngobukhulu.
Shanghai Wangyuanungumkhiqizi ochwepheshe ogxile emkhakheni wezinsimbi zokulinganisa onesipiliyoni seminyaka engaphezu kwamashumi amabili embonini. Siqoqe ulwazi oluningi olusebenzayo ekubhekaneni nemidiya ehlukahlukene egqwalisayo, izimo zokusebenza ezimbi kakhulu kanye nezimo zenqubo eziyinkimbinkimbi. Uma unezidingo noma imibuzo mayelana nokukhethaumthumeli wokucindezelaama-diaphragm, sicela ukhululeke ukuxhumana nathi. Bandakanya ingxoxo ejulile nethimba lethu lobuchwepheshe mayelana nesicelo sakho esithile ukuze uthole isisombululo sokulinganisa esifaneleka kakhulu ngokubambisana.
