Ukuphonononga imisonto ye-NPT
Yintoni imisonto ye-NPT?– Isishwankathelo
Imisonto ye-NPT, okanye imisonto ye-National Pipe Tapered, luhlobo lwentambo ye-screw edla ngokusetyenziselwa ukutywinwa kwamalungu emibhobho.Olu luyilo luqinisekisa uqhagamshelo olungavuziyo ngenxa yeprofayile yalo ecothiweyo, eya iqina njengoko ukufakwa kufakwe kumbhobho.Iteyiphu yenza itywina ngokucudisa imisonto kunye, ngokufuthi iphuculwe ngokusetyenziswa kwe PTFE tape okanye ikhompawundi yokutywina ukugcwalisa naziphi na izikhewu.
Itshathi eneenkcukacha ye-NPT yoMsonto
Xa usebenza nemisonto ye-NPT, imilinganiselo echanekileyo ibalulekile.Nantsi itshathi yomlinganiselo womsonto we-NPT eyenziwe lula:

Imisonto ye-NPT kwizicelo zoShishino
Imisonto ye-NPT ibalulekile kwizicwangciso ezahlukeneyo zemizi-mveliso.Zihlala zifumaneka kwiinkqubo zokuphatha i-hydraulic fluids apho i-seal ekhuselekileyo, i-pressure-tight-tight seal iyimfuneko.Iiadaptha ze-NPT zisetyenziselwa ukudibanisa imibhobho kunye nemibhobho yobukhulu obahlukeneyo okanye ukutshintshela kwezinye iindidi zentambo, njengodidi lwentambo ye-SAE, ukuya kwi-NPT.Xa udibanisa i-SAE fittings, enokusebenzisa inkqubo ye-Straight Thread O-Ring Boss, i-adapters iqinisekisa ukuhambelana namacandelo e-NPT-threaded.
Ukuchonga ubungakanani bemisonto yeNPT kunye neMigangatho
Ukuchonga intambo ye-NPT, kuya kufuneka wazi zombini i-diameter yangaphandle kunye nenani lemisonto nge-intshi nganye.Nasi isikhokelo esikhawulezayo:
1. Ukulinganisa i-diameter yangaphandle yomsonto oyindoda okanye i-diameter yangaphakathi yowesifazane.
2. Bala inani leencopho zemisonto kwisithuba se-intshi enye ukumisela iTPI.
3. Thelekisa le milinganiselo kunye netshati ye-NPT esemgangathweni ukufumana ubungakanani obuhambelanayo be-NPT.
Kubalulekile ukuqaphela ukuba imisonto ye-NPT ifuna uthethathethwano olululo ukuphumeza ukulingana okukhuselekileyo.Oku kuthetha ukuba imisonto yobudoda neyemazi kufuneka ijijwe kunye ngokwaneleyo ukuthintela ukuvuza, kodwa ingaqini kangangokuba ibangele umonakalo.
Uhlalutyo lokuthelekisa lwe-SAE vs. NPT Imisonto
Uyilo lwemisonto: Ngokuthe ngqo vs
Xa uvavanya i-SAE Thread Type kunye ne-NPT Thread, umahluko osisiseko uyabonakala kuyilo lwabo.Iintambo ze-SAE, ngokukodwa i-Straight Thread O-Ring Boss, zibonakaliswe ngepateni yazo eqondileyo.Olu luyilo luvumela ububanzi obuhambelanayo kubo bonke ubude bomsonto.Ngokwahlukileyo, iNational Pipe Tapered Threads (NPT) ibonisa inkangeleko ye tapered, icutheka njengoko iqhubela phambili ecaleni kwentambo yomgca.
l SAE : Imicu ethe tye, i-diameter efanayo.
l NPT : Imisonto edibeneyo, i-diameter iyancipha ecaleni komsonto.
Ubuchwephesha bokutywina: i-O-Ring vs. Taper kunye ne-Sealants
Ukutywina ingqibelelo kubalulekile ekuthinteleni ukuvuza.I-SAE Male Connector kunye ne-SAE Female Connector bahlala besebenzisa i-O-Ring ukwenza itywina.Le-O-Ringi ihlala kwigroove kwaye icinezele ekuqiniseni, yenze umqobo ngokuchasene nokuvuza.Ngeli xesha, uyilo olucekethekileyo lwemisonto ye-NPT lufuna indlela eyahlukileyo.I-taper ivumela iintambo ukuba zilungele ngakumbi njengoko zifakwe kwi-screw, ukudala uxhulumaniso olungenamanzi.Ukuphucula le mpembelelo, i-PTFE (Polytetrafluoroethylene) tape okanye ikhompawundi ye-sealant idla ngokusetyenziswa kwimisonto ye-NPT.
l SAE : Isebenzisa i -O-Ringi ukutywina.
l NPT : Ithembele kuyilo olucekethelweyo kunye nezitywini ezongezelelweyo zoqhagamshelwano olungavuziyo.
Izinto eziluncedo kwiMeko: Usetyenziswa nini i-SAE okanye i-NPT
Ukhetho phakathi kwe-SAE kunye nofakelo lwe-NPT kaninzi luxhomekeke kwisicelo esithile kunye nemigangatho yoshishino.Izixhobo ze-tube ze-SAE J514 zisetyenziswa ngokubanzi kwiinkqubo ze-hydraulic ngenxa yeendlela zabo zokutywina ezinamandla kunye nokukwazi ukumelana noxinzelelo oluphezulu.Zenzelwe ukuhlangabezana nemigangatho efana ne-SAE J518, i-DIN 20066, i-ISO/DIS 6162, kunye ne-JIS B 8363. Ezi zixhobo zilungele ukudala uxhulumaniso oluthembekileyo xa ulawula ulwelo lwe-hydraulic.
Ufakelo lwe-NPT, kwelinye icala, luhlala lufumaneka kwiinkqubo zemibhobho jikelele kunye nezomoya.I-American Standard Standard Pipe Thread (ANSI/ASME B1.20.1) ngumgangatho oqhelekileyo wale misonto ye tapered.Iiadaptha ze-NPT zifanelekile kwizicelo apho umsonto othe ngqo ungekho mfuneko okanye apho ukusetyenziswa kwe-O-Ring kungenakwenzeka.
l SAE : Ikhethwa kwiinkqubo zoxinzelelo oluphezulu lwe-hydraulic.
l NPT : Okuqhelekileyo kwimibhobho kunye nezicelo zoxinzelelo oluphantsi.
IiNdlela eziGqwesileyo zokuFakela i-SAE kunye ne-NPT yoFakelo lweMisonto
Xa uqhagamshela izixhobo ze-SAE, ukuchaneka ngundoqo.Qala ngokukhetha i-SAE Male Connector echanekileyo okanye i-SAE Female Connector.Qinisekisa ukuhambelana nemigangatho efana ne-SAE J518, i-DIN 20066, okanye i-ISO/DIS 6162. Ukulungelelaniswa okukhuselekileyo, sebenzisa i-O-ring kunye ne-flange clamp.Lungelelanisa ubungakanani bebholiti kunye neenkcukacha zokuthintela ukuhluba imisonto.
Uxhumo lwentambo ye-NPT, elawulwa yi-ANSI/ASME B1.20.1, ifuna indlela eyahlukileyo.Faka iteyiphu ye-PTFE okanye ikhompawundi efanelekileyo yokutywina kwi-MPT ukuqinisekisa ukutywinwa okungangeni manzi ngenxa yoyilo lwabo oludityanisiweyo.Kuphephe ukuqinisa kakhulu;kunokubangela iintanda okanye ukuguqula imisonto.
ULondolozo kunye nokuJonga iNgxaki kwiMiba eqhelekileyo
Ukuhlolwa rhoqo kubalulekile kwiinkqubo zamanzi.Khangela iimpawu zokugqoka kwi-SAE J514 i-tube fittings kunye nee-adapter ze-NPT.Ukuba ukuvuza kuyenzeka, hlola i-O-Ring Boss kwaye uyibuyisele endaweni ukuba yonakele.Ngemiba yentambo ye-NPT, khangela ukuba iteyiphu ye-PTFE ifuna ukuphinda isetyenziswe.Soloko unekiti yokulungisa ephathwayo ene-O-rings esecaleni, ikhompawundi ye-sealant, kunye neteyiphu ye-PTFE.
Ukuqinisekisa uBomi obude kunye nokusebenza kakuhle kwiiNkqubo zeHydraulic
Ukugcina imfezeko yesistim, landela la manyathelo:
1. Sebenzisa ulwelo oluchanekileyo lwehydraulic.
2. Cwangcisa uhlolo lwarhoqo lwalo lonke uqhagamshelo.
3. Tshintsha amalungu agugileyo ngoko nangoko.
4. Gcina imibhobho enemisonto kunye nezifakelo zemibhobho zicocekile kububutyobo.
5. Beka esweni utshintsho kwindlela yokusebenza kwenkqubo.
Ngokuthobela ezi zikhokelo, unokuqinisekisa uqhagamshelo olungavuziyo kwaye wandise ubomi benkqubo yakho yolwelo loxinzelelo olukhulu.Khumbula, uhlobo oluchanekileyo lwe-SAE Thread okanye ukhetho lwe-NPT Thread lunokwenza wonke umahluko ekudaleni amatywina asebenzayo, ahlala ixesha elide.
Ukuqukumbela
Sikhe saphonononga iinuances zeSAE kunye neNPT imisonto.Ukubuyisela kwakhona, iintambo ze-SAE zenzelwe iinkqubo ze-hydraulic, eziqukethe intambo echanekileyo kunye ne-O-ring yokutywinwa.I-SAE Male Connector kunye ne-SAE Female Connector badlala indima ebalulekileyo ekuqinisekiseni uqhagamshelwano olungavuzi.Kwelinye icala, imisonto ye-NPT, okanye imisonto ye-National Pipe Tapered, inoyilo oludityanisiweyo oludala itywina ngokuqina kokulingana, okuhlala kuphuculwe nge-PTFE tape okanye ikhompawundi ye-sealant.
Ukuwuqonda umahluko kubalulekile.Iintlobo ze-SAE Thread, ezifana ne-Straight Thread O-Ring Boss efunyenwe kwi-SAE J514 i-tube fittings, ithembele kwi-O-ring ukwenza isitywina esikhuselekileyo.Ngokuchaseneyo, imisonto ye-NPT, ehambelana ne-ANSI/ASME B1.20.1, yenza itywina ngokuphazamiseka phakathi kwemisonto.
Ukukhetha uhlobo lomsonto oluchanekileyo alunakugqithiswa.Ukungahambelani kunokukhokelela ekuvuzeni, kwiinkqubo ezisengozini, kunye nokunyusa ixesha lokunciphisa.Umzekelo, xa uqhagamshela izixhobo ze-SAE kwi-hydraulic system, qinisekisa ukuhambelana nemigangatho efana ne-SAE J518, DIN 20066, ISO/DIS 6162, okanye i-JIS B 8363. Le migangatho ithetha ngemilinganiselo, kubandakanywa ubukhulu bebholi kunye neemfuno ze-flange clamp, ukuqinisekisa ukuba ikhuselekile kwaye kufanelekile.
Kwindawo yokufakelwa kwe-hydraulic, i-SAE Thread Type isoloko idibanisa kunye ne-O-Ring Boss uxhulumaniso, ngelixa intambo ye-NPT ixhaphake kwizicelo zombhobho jikelele.Xa usebenzisa iiadaptha ze-NPT kwinkqubo eyilelwe imigangatho ye-SAE, qaphela iindlela ezahlukeneyo zokutywina.I-O-ring ibonelela ngoqhagamshelo olungaguqukiyo lwamanzi kwiinkqubo ze-SAE, ngelixa uyilo olucekethekileyo kwiinkqubo ze-NPT lufuna ubandakanyo lwemisonto ngononophelo ukuphumeza uqhagamshelo olungavuziyo.
Ukuqukumbela, ingqibelelo yoqhagamshelo lwakho-nokuba ibandakanya imibhobho ephothiweyo, ukufakwa kwemibhobho, okanye ukufakwa kwe-hydraulic-kuxhomekeke ekuchongeni okuchanekileyo kunye nokusetyenziswa kohlobo lwe-SAE Thread okanye i-NPT Thread.Ngalo lonke ixesha ubhekisele kwimigangatho yoshishino, njengaleyo ikhankanyiweyo, ukukhokela ukhetho lwakho.Khumbula, uhlobo oluchanekileyo lwentambo aluqinisekisi kuphela ukhuseleko olukhuselekileyo kodwa lugcina ukusebenza kakuhle kunye nokhuseleko lwenkqubo yakho yonke.
