Cov qauv rauastm a36 threaded pas nrignpog ntau yam tsis xws li nominal txoj kab uas hla, txhuas thiab ntev. Thaum tsim, nws yog ib qho tsim nyog los xaiv qhov tsim nyog tshwj xeeb raws li cov ntawv thov tshwj xeeb thiab cov peev txheej thauj khoom.
a193b 7 uaa449 threaded pas nrig nominal txoj kab uas hla:
a449 xovmuaj ntau yam ntawm nominal diameters, thiab ntau specificationstxheem threaded pas nrig qhov ntau thiab tsawg cov khoommuaj 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120, thiab lwm yam. lwm txoj kab uas hla yog yav tom ntej, uas yog, lawv tau tsim raws li kev txiav txim, thiab lub sijhawm xa khoom feem ntau yog nyob nruab nrab ntawm 30 thiab 60 hnub, uas tej zaum yuav yog 2 mus rau 2.5 lub hlis rau cov khoom Japanese thiab 3 mus rau 4 lub hlis rau cov khoom European thiab Asmeskas. Lub nominal txoj kab uas hla yog qhov yooj yim proportional rau lub peev xwm load, uas yog, qhov loj ntawm txoj kab uas hla, lub load muaj peev xwm ntau dua. Thaum tsim, cov ntsiab lus ntawm dynamic rated load thiab static rated load yuav tsum raug xa mus rau, qhov twg dynamic rated load yog hais txog cov rated axial load nyob rau hauv lub xeev txav, thiab static rated load hais txog qhov ntsuas axial load nyob rau hauv lub xeev zoo li qub. Hauv kev siv tiag tiag, qhov ntsuas ntsuas tsis yog qhov siab tshaj plaws. Qhov tsawg dua qhov piv ntawm qhov tseeb load rau qhov ntsuas load, lub neej theoretical ntev ntawm cov ntsia hlau.
stainless hlau threaded pas nrig astm Lead
kuj hu ua suab, hais txog qhov kev ncua deb ntawm cov txiv ntoo txav linearly rau txhua qhov kev sib hloov ntawm cov ntsia hlau.Stainless hlau threaded pas nrig astm chaw tsim tshuaj pausCov khoom siv txhuas feem ntau suav nrog 1, 2, 4, 6, 8, 10, 16, 20, 25, 32, 40, thiab lwm yam. Cov khoom siv ntawm cov khoom me me thiab nruab nrab feem ntau tsuas yog 5 thiab 10, thaum cov hlau lead loj feem ntau yog yav tom ntej. Lead muaj feem xyuam rau linear ceev. Thaum cov input ceev tsis tu ncua, qhov loj dua cov hlau lead, qhov ceev ceev.
astm f593 threaded pas nrig ntev
Qhov ntev ntawm covastm f593 threaded qws khoomsuav nrog ob lub ntsiab lus: tag nrho ntev thiab cov xov ntev. Thaum tsim thiab kos duab, tag nrho qhov ntev ntawm cov ntsia hlau tuaj yeem sib sau ua ke raws li cov hauv qab no: tag nrho qhov ntev ntawm cov ntsia hlau = zoo stroke + txiv ntseej ntev + tsim npoo + txhawb nqa ntev ntawm ob qhov kawg (cov kabmob dav + xauv txiv ntseej dav + npoo. ) + fais fab input txuas ntev (yog tias siv cov coupling, nws yog kwv yees li ib nrab ntawm qhov ntev ntawm qhov txuas + npoo). Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tias yog tias qhov ntev ntawm cov ntsia hlau ntev ntev (ntau dua 3 meters) lossis qhov sib piv loj heev (ntau dua 70), nws tsim thiab daim ntawv thov yuav xav tau kev txiav txim siab tshwj xeeb.
