Njengezixhobo zokuqonda eziphambili kwiinkqubo zolawulo lwe-automation yemizi-mveliso,abathumeli boxinzeleloIhlala idibana neendawo zokulinganisa ezinzima kumashishini enkqubo yanamhlanje afana nepetroleum, iikhemikhali, amandla, ukutya, kunye namayeza. I-diaphragm yayo ye-sensor ayisiyonto yokuva nje kuphela yokudlulisa uxinzelelo kodwa ikwangumgca wokuqala wokuzikhusela, ihlukanisa indlela yokusebenza kwi-fill fluid yangaphakathi kwaye ithintela umonakalo we-sensor. Isayensi yezinto ezibonakalayo kunye noyilo lwesakhiwo se-diaphragm zibalulekile ekusombululeni iimeko zokusebenza ezinzima. Ukukhetha ngokuchanekileyo kunokukhokelela kwimiba eqala ekunyukeni komlinganiselo ukuya ekugqobhozeni kwe-diaphragm, ukukrazulwa kwezixhobo, kwaneengozi zokhuseleko. Ukukhetha ngokuchanekileyo i-pressure transmitter linyathelo elibalulekileyo ekuqinisekiseni ukusebenza okuzinzileyo, okuthembekileyo nokunoqoqosho kwenkqubo yonke yokulinganisa.
Iimpawu zeKhemikhali Ukhetho lweDrive Diaphragm
Ukuhambelana kweekhemikhali kwezinto ze-diaphragm yeyona nto iphambili ekukhetheni imodeli. Ii-media ezahlukeneyo zineendlela ezahlukeneyo zokubola kwizinto zesinyithi, ezifuna uhlalutyo olusekelwe kulwakhiwo lwazo lweekhemikhali kunye neempawu zokubola. Kwi-media ezibola kakhulu ezifana nee-asidi ezinamandla kunye ne-alkalis, intsimbi engagqwaliyo ye-316L eqhelekileyo isenokungahlangabezani neemfuno zozinzo lwexesha elide. Umzekelo, kwiindawo ezine-sulfuric acid okanye i-phosphoric acid kubushushu begumbi, i-Hastelloy C-276 iba lukhetho olufanelekileyo ngenxa yokuchasana kwayo okuhle nokubola okuvela ekunciphiseni i-medium. I-diaphragm ye-Tantalum ibonisa ukungangeni ngokupheleleyo kweekhemikhali xa ivezwa kwi-medium exineneyo kakhulu efana ne-nitric acid, kodwa ixabiso eliphezulu lidla ngokunciphisa ukusetyenziswa kwayo kwiziganeko ezikhethekileyo ezifana neekhemikhali ezintle okanye imveliso yeekhemikhali ezicocekileyo kakhulu. Kwi-marine engineering okanye kwiindawo ezinee-chloride, ii-ion ze-chloride zinokubangela ukubola kwe-pitting kwintsimbi eqhelekileyo engagqwaliyo. Apha, i-Monel yamkelwe ngokubanzi ngenxa yokukwazi kwayo ukudlulisa amanzi olwandle kunye nesisombululo se-brine.
Imeko Ephakathi Yomzimba Ilawula Ulwakhiwo Lwe-Diaphragm
Uhlobo olubonakalayo lwesixhobo (umz., ukuxinana, umxholo oqinileyo) luchaphazela ngokuthe ngqo ukukhethwa kwesakhiwo se-diaphragm. Kwisixhobo esiphakathi esixineneyo kakhulu okanye esithambekele ekukhanyeni, izakhiwo zesiqhelo ezine-inlet encinci yoxinzelelo zisengozini enkulu yokuvaleka, nto leyo ekhokelela ekusileleni kokudluliselwa koxinzelelo.Uyilo lwe-diaphragm oluthe tyabaingasetyenziswa kwiimeko ezinjalo ezisusa i-pressure port kwaye ivumele i-diaphragm ukuba iqhagamshelane ngqo ne-medium. Isakhiwo se-flush mount asinakuthintela kuphela ukuvaleka kodwa sikwahlangabezana neemfuno zoyilo lococeko kumashishini okutya namayeza ngenxa yokunqongophala kweendawo eziqinileyo. Xa i-medium inee-slid particles, i-diaphragm ijongene nomngcipheko omkhulu wokuguguleka. Ii-ceramic diaphragms zinokumelana ngempumelelo nokuguguleka kwee-particles ngenxa yobunzima bazo obuphezulu kakhulu kunye nokumelana nokuguguleka. Ezinye iindlela ezigqithisileyo zingasebenzisa ii-hard-faced flush diaphragms ukwandisa ubomi benkonzo yezixhobo phantsi kweemeko ezinzima.
Izisombululo Zokuziqhelanisa Neemeko Ezinzima Zokusebenza
Kwiindawo ezinobushushu obuphezulu benkqubo, ukusebenza kwe-thermodynamic kwendibano yesensa kubalulekile. Ulwelo oluzaliswayo kufuneka lube yioyile ye-silicone yobushushu obuphezulu ukuthintela ukufuma kwe-medium ehambisa uxinzelelo, kunyeizitywino ze-capillary ezikude, izinto zokupholisaokanye amanye amanyathelo okusasaza ubushushu ukukhusela izinto ze-elektroniki kumonakalo obangelwa kubushushu obuphezulu. Usetyenziso olubandakanya umxholo omkhulu we-hydrogen lufuna ii-diaphragms ezifakwe igolide ukuthintela ukuqhekeka kwe-hydrogen. Kwimeko apho uxinzelelo oluphakathi lutshintsha kakhulu (umz., xa itephu yoxinzelelo ikufutshane nendawo yokuphuma kwepompo), ukufaka i-pulsation damper kufuneka kuthathelwe ingqalelo ukunciphisa ukuguquguquka kwesignali.
