Kwiinkqubo zoshishino ezifana nokuveliswa kombane, ukwenziwa kweekhemikhali, ukucocwa kweoyile, kunye ne-metallurgy, ukulinganisa ngokuchanekileyo uxinzelelo kwiindawo ezinobushushu obuphezulu kunokuba ngumsebenzi obalulekileyo kodwa onzima. Xa ubushushu obuphakathi benkqubo bunyuka ngaphezu kwama-80℃, abathumeli boxinzelelo abaqhelekileyo banokuba sesichengeni. Ukuvezwa ngqo kubushushu obunjalo kunokonakalisa izinto ze-elektroniki, kubangele ukushukuma komlinganiselo, konakalisa ulwelo lokuzalisa lwangaphakathi, kwaye ekugqibeleni kukhokelele ekungasebenzi kakuhle kwezixhobo. Impumelelo kwezi zicelo zinzima ixhomekeke kwisicwangciso esipheleleyo esiquka ukuqwalaselwa ngononophelo kwindawo efanelekileyo yokufakela, izixhobo, indlela yoqhagamshelo kunye nemodeli yothumelo.
Iityhubhu kunye nezixhobo
Eyona ndlela ilula kukusebenzisa iityhubhu kunye nezixhobo ezipholisa indlela yokusebenza ngaphambi kokuba ifikelele kwisensor yomthumeli. Oku kuvumela ukusetyenziswa kweemodeli zomthumeli ezisemgangathweni nezingabizi kakhulu. Lo mgaqo uxhomekeke ekupheliseni ubushushu ngokusebenzisa imibhobho emide okanye umthamo oqulethweyo.
Ityhubhu ye-Impulse okanye i-Syphon: Endaweni yokufaka i-transmitter ngqo kuqhagamshelo lwenkqubo, incamathiselwa ngomgca wobude be-impulse. Njengoko i-hot medium ihamba kwinethiwekhi yetyhubhu, ilahlekelwa bubushushu endleleni eya emoyeni ojikelezileyo. I-Syphon (ekwaziwa ngokuba yi-pigtail) yityhubhu yesinyithi esijikelezayo efakwe phakathi koqhagamshelo lwenkqubo kunye ne-transmitter. Yenzelwe ukupholisa i-medium ngaphakathi kunye nokunciphisa isiphumo sokunyuka koxinzelelo ngokukhawuleza, oku kusebenza ngakumbi kwaye konga indawo xa kuthelekiswa nokulungiselela ityhubhu ende ye-impulse.
Iivalvu kunye neeManifolds: Ezi manifolds zezinye izinto eziqhelekileyo ezisetyenziswa phakathi kwenkqubo kunye nesixhobo sokwahlulahlula, ukukhupha umoya kunye nokulinganisela. Ukongeza kwimisebenzi yayo ephambili, indibano yevalvu kunye netyhubhu yokudibanisa ikwakwazi ukukhupha ubushushu obuncinci kwindawo engqongileyo ngokuhambisa ubushushu kunye nokuhambisa umoya kwendalo.
Ukusetyenziswa okudibeneyo kweetyhubhu kunye neendibano kunokunciphisa ubushushu obuphakathi obufikelela kunxibelelwano lwenkqubo ukuya kwinqanaba elithile. Ukuba inokulawulwa ngaphakathi kobubanzi be-ambient, le ndlela imele isisombululo esingabizi kakhulu nesifanelekileyo, njengokoabathumeli abaqhelekileyoingasetyenziswa ngokuthe ngqo. Nangona kunjalo, ukuba ubushushu obuphakathi buphezulu kakhulu kwaye budlula amandla okupholisa, kufuneka kuqwalaselwe ezinye izisombululo zobushushu obuphezulu.
Iimodeli zoThumeli zoBushushu obuPhezulu
Xa izixhobo zokupholisa zingasebenzi okanye indawo incinci,abathumeliEyona ndlela yenzelwe ngokukodwa inkonzo yobushushu obuphezulu. Ayizoyunithi eziqhelekileyo nje ezinereyithingi ephezulu, kodwa zibandakanya uhlengahlengiso oluphathekayo nolwezinto eziphathekayo.
Izinki zobushushu ezidityanisiweyo:Uphawu olucacileyo zii-heat sinks ezininzi ezinkulu nezinamafindo eziqhotyoshelwe phakathi koqhagamshelo lwenkqubo kunye ne-electronics housing. Ezi fins ziyandisa kakhulu indawo yomphezulu, zikhupha ubushushu ngaphandle ngaphambi kokuba zifikelele kwi-critical sensing component kunye ne-module. Olu yilo lunokunciphisa ngempumelelo ubushushu kwi-sensor nakwi-electronics.
Izinto ezilinganiswe ngamaqondo obushushu aphezulu:Ezi transmitters zisebenzisa ii-semiconductors, ii-gaskets, kunye nolwelo lokuzalisa lwangaphakathi olwenzelwe ngokukodwa ukuzinza ixesha elide kumaqondo obushushu aphezulu. Imingxunya yangaphakathi ye-lead izaliswe ngezinto zokukhusela ubushushu ezisebenzayo, ezithintela ngempumelelo ukuhanjiswa kobushushu kwaye ziqinisekise ukuba isekethe yokukhulisa kunye nokuguqula isebenza ngaphakathi kwemida yobushushu evumelekileyo.
Inkqubo yokuTywina ekude
Kwizicelo ezinzima kakhulu—ezibandakanya amaqondo obushushu aphezulu kakhulu, imidiya ebolileyo, ulwelo oluxineneyo, okanye iinkqubo apho ukuqina kwimigca yempembelelo kuyingozi—inkqubo yokutywina ekudeyeyona ndlela ikhethwayo nebalulekileyo. Le ndlela ingayisusa ngokupheleleyo i-pressure transmitter kwindawo eshushu.
Le nkqubo inesitywina se-diaphragm esikude, ityhubhu ye-capillary enobude obumiselweyo, kunye nesidluliseli ngokwaso. Yonke inkqubo—isitywina, i-capillary, kunye ne-transmitter sensor—izaliswa kwangaphambili ngolwelo oluzinzileyo nolungacinezekiyo (umz., ioyile ye-silicone eshushu kakhulu).
Uxinzelelo lwenkqubo lujika i-diaphragm ekude. Olu jika ludluliselwa nge-hydraulic ngokusebenzisa ulwelo oluzaliswayo oluzinzileyo ngaphakathi kwi-capillary ukuya kwi-diaphragm efumanayo kwi-transmitter, efakwe kwindawo ekhuselekileyo, epholileyo, mhlawumbi kwiimitha ukusuka kwindawo yokulinganisa yokwenyani. Umzimba we-transmitter awukaze uqhagamshelane ne-hot process medium.
Ukulinganisa uxinzelelo kwiinkqubo zobushushu obuphezulu ngumceli mngeni oqhelekileyo kodwa obalulekileyo kwi-automation yemizi-mveliso. Icebo elifanelekileyo lokukhusela lixhomekeke kuhlalutyo olupheleleyo lwesicelo. Ngokusebenzisa izixhobo zokupholisa, ukukhetha izithumeli zobushushu obuphezulu ezakhiwe ngenjongo, okanye ukusebenzisa iinkqubo zokutywina ezikude, iinjineli zinokuqinisekisa ukuba izixhobo zazo zoxinzelelo zibonelela ngokuchaneka nokuthembeka okuhlala ixesha elide.Shanghai Wangyuanlishishini lokuvelisa elinobuchwepheshe obuphezulu elinamava angaphezu kweminyaka engama-20, eligxile kwimveliso kunye nenkonzo yezixhobo zokulinganisa uxinzelelo. Sinolwazi olubanzi ekuphatheni izisombululo zolawulo lwenkqubo yentsimi yobushushu obuphezulu, ezixhaswa zizifundo ezininzi ezisebenzayo. Ukuba unayo nayiphi na imfuneko okanye imibuzo malunga nokukhetha i-transmitter kwizicelo zobushushu obuphezulu, nceda uzive ukhululekile ukunxibelelana nathi nangaliphi na ixesha.
