NPT Threads muIndasitiri Zvishandiso
NPT tambo dzakabatanidzwa mune akasiyana maindasitiri marongero.Iwo anowanzo kuwanikwa mumasisitimu anobata hydraulic zvinwiwa uko kuchengetedzeka, kudzvanywa-kusimba chisimbiso kunodiwa.Maadapter eNPT anoshandiswa kubatanidza hose nemapombi ehukuru hwakasiyana kana kushandura kubva kune dzimwe mhando dzeshinda, senge SAE thread type, kuenda kuNPT.Kana uchibatanidza SAE fittings, iyo inogona kushandisa Straight Thread O-Ring Boss system, maadapter anovimbisa kuenderana neNPT-tambo dzakarukwa.
Kuziva NPT Thread Saizi uye Mayero
Kuti uzive shinda yeNPT, unozoda kuziva zvese dhayamita rekunze uye huwandu hweshinda painch.Heino gwara rekukurumidza:
1. Pima dhayamita rekunze reshinda yechirume kana dhayamita yemukati yeshinda yechikadzi.
2. Verenga huwandu hwemashinda eshinda mune imwe-inch span kuti uone TPI.
3. Enzanisa zviyero izvi nechati cheNPT kuti uwane saizi yeNPT inoenderana.
Izvo zvakakosha kuti uzive kuti tambo dzeNPT dzinoda kubatanidzwa kwakaringana kuti uwane yakachengeteka kukwana.Izvi zvinoreva kuti tambo dzechirume nedzechikadzi dzinofanirwa kubatanidzwa pamwe chete zvakakwana kudzivirira kudonha, asi kwete kusimba zvekukonzera kukuvara.
Kuenzanisa Ongororo yeSAE vs. NPT Threads
Thread Design: Straight vs. Tapered
Kana uchiongorora SAE Thread Type uye NPT Thread, mutsauko wakakosha unoonekwa mumagadzirirwo avo.SAE tambo, kunyanya iyo Yakatwasuka Thread O-Ring Boss, inoratidzirwa netambo yavo yakatwasuka.Iyi dhizaini inobvumira dhayamita inowirirana mukati mehurefu hweshinda.Mukupesana, National Pipe Tapered Threads (NPT) inoratidza tapered mbiri, ichitetepa sezvavanofambira mberi netambo axis.
l SAE : Shinda dzakatwasuka, yunifomu dhayamita.
l NPT : Tapered shinda, dhayamita inoderera pamwe neshinda.
Kuisa Chisimbiso: O-Ring vs. Taper uye Sealants
Kuisa chisimbiso kutendeseka kwakakosha mukudzivirira kudonha.Iyo SAE Male Connector uye SAE Female Connector inowanzo shandisa O-Ring kugadzira chisimbiso.Iyi O-Ring inogara mugorofu uye inomanikidza pakusimbisa, ichigadzira chipingamupinyi kurwisa kuvuza.Zvichakadaro, iyo tapered dhizaini yeNPT shinda inoda imwe nzira.Iyo taper inobvumira tambo kuti dzikwane zvakanyanya sezvadzinokwizwa mukati, dzichigadzira kubatana kwemvura.Kuwedzera mhedzisiro iyi, PTFE (Polytetrafluoroethylene) tepi kana sealant compound inowanzoiswa kune NPT tambo.
l SAE : Inoshandisa O-Ring yekuisa chisimbiso.
l NPT : Inotsamira pane tapered dhizaini uye ekuwedzera zvisimbiso kune inovuza-isina kubatana.
Mamiriro Akanakira: Nguva Yekushandisa SAE kana NPT
Sarudzo pakati peSAE neNPT fittings inowanzoenderana neiyo chaiyo application uye indasitiri zviyero.SAE J514 tube fittings inoshandiswa zvakanyanya mu hydraulic systems nekuda kwemaitiro avo akasimba ekuisa chisimbiso uye kukwanisa kumira zvakasimba.Izvo zvakagadzirirwa kuti zvienderane nemitemo yakadai seSAE J518, DIN 20066, ISO/DIS 6162, uye JIS B 8363. Izvi zvinogadziriswa zvakakosha pakugadzira hukama hwakavimbika paunenge uchigadzirisa hydraulic fluids.
NPT fittings, kune rumwe rutivi, inowanzowanikwa mune zvakajairika pombi dzemvura uye mhepo masisitimu.The American National Standard Pipe Thread (ANSI/ASME B1.20.1) ndiwo muyero wakajairika kune idzi shinda dzakatepwa.NPT adapters akakodzera maapplication uko yakatwasuka shinda isingakodzeri kana uko kushandiswa kweO-Ring kusingagoneke.
