Falanqaynta Isbarbardhigga ee SAE vs. Xargaha NPT

Naqshadaynta dunta: Toosan vs. Tapered

Marka la baarayo nooca SAE Thread iyo NPT Thread, farqi aasaasi ah ayaa ka muuqda naqshadahooda. Xadhkaha SAE, gaar ahaan xadhigga toosan ee O-Ring Boss, waxa lagu gartaa qaabkooda dunta toosan. Naqshadeyntani waxay u oggolaaneysaa dhexroor joogto ah oo dhan dhererka dunta. Taas bedelkeeda, Xadhkaha Xadhkaha Leh ee Qaranka (NPT) waxay muujinayaan muuqaal duuban, oo soo cidhiidhinaya markay sii socdaan dhidibka dunta.

l  SAE : dunta toosan, dhexroor isku mid ah.

l  NPT : Xadhkaha duuban, dhexroorku wuu yareeyaa dunta.

Farsamooyinka Xiritaanka: O-Ring vs. Taper iyo Sealants

Xaqiijinta daacadnimada ayaa muhiim u ah ka hortagga daadinta. Xidhiidhiyaha Labka ah ee SAE iyo xidhiidhiyaha dheddig ee SAE waxay inta badan shaqaaleeyaan O-ring si ay u abuuraan shaabad. O-Ring-kani waxa uu ku fadhiyaa meel jeexdin ah oo isku ururiya marka la adkeeyo, isaga oo ka dhigaya xannibaad ka soo horjeeda dareeraha. Dhanka kale, naqshadeynta duuban ee dunta NPT waxay u baahan tahay hab ka duwan. Taperku wuxuu u oggolaanayaa in duntu ay si aad ah ugu dhejiyaan marka la isku dhejiyo, abuurista xiriir aan biyuhu lahayn. Si loo wanaajiyo saamayntan, cajalad PTFE (Polytetrafluoroethylene) ama iskudhis xidhe ah ayaa badanaa lagu dabaqaa dunta NPT.

l  SAE : Waxay u isticmaashaa O-ring  si loo xidho.

l  NPT : Waxay ku tiirsan tahay naqshadda duuban iyo shaabadeynta dheeraadka ah  ee xiriir la'aanta.

Faa'iidooyinka Xaaladda: Goorta la Isticmaalayo SAE ama NPT

Doorashada u dhaxaysa qalabka SAE iyo NPT waxay inta badan ku xiran tahay codsiga gaarka ah iyo heerarka warshadaha. Qalabka tuubada SAE J514 ayaa si weyn loogu isticmaalaa nidaamyada hawo-mareenka sababtoo ah hababka xirmooyinkooda adag iyo awoodda ay u leeyihiin inay u adkeystaan ​​cadaadiska sare. Waxaa loogu talagalay inay la kulmaan heerarka sida SAE J518, DIN 20066, ISO/DIS 6162, iyo JIS B 8363. Qalabkani wuxuu ku habboon yahay abuurista xiriir la isku halayn karo marka la maamulayo dareeraha hydraulic.

Qalabka NPT, dhanka kale, waxaa badanaa laga helaa tuubooyinka guud iyo nidaamyada hawada. Xadhkaha Tubooyinka Halbeegga Qaranka Mareykanka (ANSI/ASME B1.20.1) waa halbeeg caadi ah oo loogu talagalay duntan duuban. Adabiyeyaasha NPT waxay ku habboon yihiin codsiyada halka dunta toosan aysan lagama maarmaan ahayn ama halka isticmaalka O-ring aysan suurtagal ahayn.

l  SAE : Waxaa loo door bidaa nidaamyada hydraulic cadaadis-sare.

l  NPT : Waxay ku badan yihiin codsiyada tuubooyinka iyo cadaadiska hoose.

Hababka ugu Fiican ee Ku rakibida Sae iyo Qalabka Isku Xidhan ee NPT

Marka la isku xidho qalabka SAE, saxnimadu waa furaha. Ku bilow inaad doorato isku xidhaha lab ee SAE saxda ah ama xidhiidhiyaha dheddig ee SAE. Hubi in ay waafaqsan yihiin halbeegyada sida SAE J518, DIN 20066, ama ISO/DIS 6162. Ku toosi cabbirrada boodhka iyo qeexitaannada si aad uga fogaato xadhigga dunta.

Xidhiidhada dunta NPT, ee ay maamusho ANSI/ASME B1.20.1, waxay u baahan yihiin hab ka duwan. Codso cajalad PTFE ama xarun ku habboon oo xidhidhiyaha MPT si aad u hubiso shaabad biyo-xidheen ah sababtoo ah naqshadooda duuban. Iska ilaali inaad aad u adkeyso; waxay keeni kartaa dildilaac ama qallafsanaanta dunta.

Dayactirka iyo Cilad-bixinta Arrimaha Guud

Baaritaanka joogtada ah ayaa muhiim u ah hababka hawo-mareenada. Ka raadi calaamadaha xirashada tuubooyinka SAE J514 iyo adabiyeyaasha NPT. Haddii daadadku dhacaan, fiiri O-Ring Boss oo beddel haddii ay wax gaareen. Arrimaha dunta NPT, hubi haddii cajaladda PTFE ay u baahan tahay dib u codsi. Had iyo jeer hay qalabka dayactirka oo ku anfacaya oo leh O-rings-ka-faa'iidi ah, isku-xidhka daboolka, iyo cajaladda PTFE.

Xaqiijinta Cimri dheer iyo Hufnaan Nidaamyada Haydarooliga

Si loo ilaaliyo sharafta nidaamka, raac tillaabooyinkan:

1. Isticmaal dareeraha biyo-biyoodka saxda ah.

2. Jadwal u samee kormeerada joogtada ah ee dhammaan xiriirada.

3. Beddel qaybaha xiran isla markiiba.

4. Tuubooyinka dunta leh iyo tuubooyinka tuubooyinka ka fogee qashinka.

5. La soco isbeddelada waxqabadka nidaamka

Markaad raacdo tilmaamahan, waxaad xaqiijin kartaa isku xidhka bilaa daadsan oo aad sii dheerayn kartaa nolosha nidaamkaaga biyo-xidheenka. Xusuusnow, nooca saxda ah ee SAE Thread Type ama NPT Thread wuxuu sameyn karaa dhammaan faraqa abuurista shaabad hufan oo waara.

Gabagabo

Waxaan sahaminay nuucyada SAE iyo dunta NPT. Si loo soo celiyo, dunta SAE waxaa loogu talagalay nidaamyada hawo-biyoodka, oo muujinaya dun toosan oo leh O-ring si loo xiro. Xidhiidhiyaha Labka ah ee SAE iyo xidhiidhiyaha dheddigga ee SAE ayaa door muhiim ah ka ciyaara hubinta xidhiidh la'aan. Dhanka kale, dunta NPT, ama dunta tuubada Qaranka, waxay leeyihiin naqshad duuban oo abuurta shaabad iyada oo loo marayo cidhiidhiga ku habboonaanta, oo inta badan lagu xoojiyay cajaladda PTFE ama iskudarka daboolka.

Fahamka kala duwanaanshaha waa muhiim. Noocyada SAE Thread, sida O-Ring Boss-ka Toosan ee laga helay tuubbooyinka SAE J514, waxay ku tiirsan yihiin O-ring si loo abuuro shaabad sugan. Taas bedelkeeda, dunta NPT, oo waafaqsan ANSI/ASME B1.20.1, waxay abuuraan shaabad faragelinta u dhaxaysa dunta.

Doorashada nooca dunta saxda ah lama soo koobi karo Is-waafajin la'aantu waxay horseedi kartaa daadad, nidaamyo jaban, iyo korodhka wakhtiga hoos u dhaca. Tusaale ahaan, marka la isku xidho qalabka SAE ee hab-dhismeed-biyoodka, hubi in ay waafaqsan yihiin heerarka sida SAE J518, DIN 20066, ISO/DIS 6162, ama JIS B 8363. Heerarkani waxay la hadlayaan cabbirrada, oo ay ku jiraan cabbirrada boodhka iyo shuruudaha xajinta flange, hubinta ku habboonaanta ammaan iyo habboon.

Dhinaca qalabka hawo-mareenada, SAE Thread Type inta badan waxay isku xidhaa O-Ring Boss isku xirka, halka dunta NPT ay ku badan tahay codsiyada tuubooyinka guud. Markaad isticmaalayso adapters NPT hab loogu talagalay heerarka SAE, ka fiirso hababka kala duwan ee xirida. Giraanta O-ring waxa ay bixisaa xidhiidh aan biyo lahayn oo joogto ah oo ku jira nidaamyada SAE, halka nakhshad duuban ee nidaamyada NPT ay u baahan tahay ka-qaybgal taxaddar leh si loo gaadho xidhiidh-la'aan.

 

Gebogebadii, daacadnimada isku xidhkaaga-haddii ay ku lug leeyihiin tuubooyinka dunta leh, xidhmooyinka tuubooyinka, ama qalabka hawo-mareenka-waxay ku xidhan yihiin aqoonsiga saxda ah iyo codsiga nooca SAE Thread Type ama NPT Thread. Had iyo jeer tixraac heerarka warshadaha, sida kuwa lagu xusay, si aad u hagto doorashadaada. Xusuusnow, nooca dunta saxda ah kaliya ma hubiso taam sugan laakiin sidoo kale waxay ilaalinaysaa waxtarka iyo badbaadada nidaamkaaga oo dhan.
