Ku-Xidhiidhinta Awoodda Dheecaannada Haydarooliga Ku-Xidhiidhiyeyaasha NPT / Adapters
Hordhac Product
Summada guuleystaha NPT xirayaasha ugu yaraan waxay leeyihiin dunta NPT lab ama dheddig waxay ku xirmaan dhamaadka xiriiriyaha, NPT waa dunta tuubooyinka Qaranka Mareykanka, oo sidoo kale loo yaqaanno dunta tuubooyinka ANSI/ASME B1.20.2M.
Dufanka NPT wuxuu leeyahay sifooyin hoos ku qoran:
1. Jeexitaanka xididdada iyo duntu waa siman yihiin
2.60° xagal dunta
3.Xagalka u dhexeeya dhidibka taper iyo dhexda dunta tuubada waa 1°47'24”
4. Dhererka xargaha oo lagu qiyaaso halkii inch.
Sababtoo ah gooynta dunta NPT ee xididada iyo cidhifyada duntu waa fidsan yihiin, way ka duwan tahay NPTF, markaa sharoobada PTFE waa in la isticmaalaa si loo hubiyo shaabad aan daadan lahayn, ka dibna la siiyo shaabad wax ku ool ah xirayaasha isticmaalaya dareerayaasha Haydarooliga.
Cabbirrada dunta NPT ee xiriiriyeyaasha guuleysta waxaa ka mid ah: 1/8"-27, 1/4" -18, 3/8" -18, 1/2" -14, 3/4" -14, 1"-11.5, 1.1/ 4"-11.5, 1.1/2"-11.5, 2"-11.5.
Sida loo aqoonsado dunta NPT oo loo go'aamiyo xajmiga dunta?
1.Visual inspection dunta iyo waa taper, ama isticmaal caliper cabbiro dhexroor ka baxay dunta dibadda ama dhexroor yar ee dunta gudaha booska dhererka kala duwan oo la helay dhexroor ka duwan yahay oo la kulmo 1:16 taper, ama si toos ah u isticmaal a 1:16 koontada cabbirka.
2.Isticmaal caliper cabbir dhexroorka booska khadka saldhiga.Ku qiyaas dhexroorka dunta oo leh ID/OD caliper, dhexroorka dunta dibadda waxa lagu cabbiraa dhexroorka bannaanka, oo ku hay caliper xagal yar si aad u akhrido sax ah, waayo dunta gudaha waxa lagu cabbiraa dhexroorka gudaha, oo ku hay si toos ah dunta loogu talagalay akhris sax ah oo dumar ah.
3. Cabir xadhkaha halkii inch (TPI) ama garoonka.Sida dhexroorka la cabbiray oo isticmaal cabbirka garoonka, isku day qiyaasaha dunta kala duwan ilaa la go'aamiyo taam ugu adag, geli dunta badan intii suurtogal ah, waxaa jira dun badan oo ku hawlan, inta badan akhrinta saxda ah.Ku hay qalabka ku habboon ee isku xidhka iyo dunta dunta ilaa iftiinka, adigoo eegaya meelaha bannaan ee u dhexeeya cabbirka iyo dunta, tani way fududahay in lagu arko dunta dibadda ee ku habboon ee ku habboon / isku xidhka dunta gudaha.Ama si toos ah u cabbir masaafada labada dunood ee cufan
sababtoo ah in ka badan hal cabbir ayaa yeelan kara cabbirro dun ah oo isku mid ah.Hoos waxaa ku yaal xogta marka la barbardhigoNdunta PT vs dunta BSPT, way la mid tahay, markaa si taxadar leh ha u qasin ama ha khaldin.
