Hydraulic Fluid Imbaraga Zihuza Uwatsinze NPT Umuhuza / Adapters
Kumenyekanisha ibicuruzwa
Intsinzi yerekana NPT ihuza byibuze ifite NPT umugozi wumugabo cyangwa uwomugore uhuza impera, umuhuza NPT numuyoboro wumunyamerika wapanze, uzwi kandi nka ANSI / ASME B1.20.2M.
Urudodo rwa NPT rufite ibintu bikurikira:
1.Gucamo imizi nigitereko cyurudodo kiringaniye
2.60 ° inguni
3.Impande iri hagati ya taper na hagati ya axe y'urudodo ni 1 ° 47'24 ”
4.Ikibanza cyo gusoma cyapimwe kuri santimetero.
Kuberako urudodo rwa NPT rugabanije imizi hamwe nigitereko cyurudodo ruringaniye, biratandukanye na NPTF, bityo kaseti ya PTFE igomba gukoreshwa kugirango tumenye neza ko kashe idasohoka, hanyuma utange kashe nziza kubihuza ukoresheje amazi ya hydraulic.
Ingano ya NPT ihuza abatsinze harimo: 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.
Nigute ushobora kumenya ko ari urudodo rwa NPT no kumenya ingano yumurongo?
1.Gusuzuma mu buryo bugaragara urudodo kandi ni taper, cyangwa ukoreshe Caliper gupima diameter yo hanze yumurongo winyuma cyangwa diameter ntoya yumutwe wimbere mumwanya muremure ugasanga diameter itandukanye kandi ihura na taper 1:16, cyangwa ukoreshe a Igipimo cya cone.
2. Koresha Caliper gupima diameter yumurongo wibanze.Gupima umurambararo wa diameter hamwe na ID / OD caliper, umurambararo wurudodo rwo hanze urapimwa kuri diametre yo hanze, hanyuma ugafata Caliper kumurongo muto kugirango usome neza, kuko urudodo rwimbere rupimwa kuri diameter y'imbere, hanyuma ukarufata kuri perpendicular kuri urudodo rwo gusoma neza.
3.Gupima insinga kuri santimetero (TPI) cyangwa ikibuga.Nka diametero yapimwe kandi ukoreshe igipimo gifitanye isano, gerageza gupima urudodo rutandukanye kugeza igihe umenye neza, uhuze insanganyamatsiko nyinshi zishoboka, hariho urudodo rwinshi rwasabwe, nukuri gusoma neza.Fata igikwiye / uhuza hamwe nudupapuro twa pisine kugeza kumucyo, ushakisha icyuho kiri hagati yikigereranyo nu mugozi, ibi biroroshye kubona kumurongo wo hanze uhuza / uhuza kuruta umugozi wimbere uhuza / uhuza.Cyangwa gupima mu buryo butaziguye intera yimigozi ibiri
kuberako ubunini burenze bumwe bushobora kugira ibipimo bisa.Hasi namakuru agereranya hagatiNUrudodo rwa PT vs BSPT, birasa, rero ukeneye kwitonda ntukavange cyangwa wibeshye.
