Lub luj tshib muab faib ua lub vojvoog ntev thiab luv luv
Txoj kev faib tawm ntawm lub luj tshib tuaj yeem muab faib ua lub luj tshib ntev thiab lub luj tshib luv luv raws li nws lub vojvoog ntawm curvature. Lub luj tshib ntev txhais tau hais tias nws lub vojvoog ntawm curvature yog sib npaug li 1.5 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab, uas yog, R=1.5D. Lub luj tshib luv luv txhais tau hais tias nws lub vojvoog ntawm curvature yog sib npaug rau sab nraud ntawm cov yeeb nkab, uas yog, R=D. D hauv cov mis yog lub luj tshib txoj kab uas hla thiab R yog lub vojvoog ntawm curvature. Lub luj tshib feem ntau yog 1.5D. Yog hais tias nws tsis tau teev nyob rau hauv daim ntawv cog lus raws li 1D los yog 1.5D, ces 1.5D yuav tsum optimized. Feem ntau siv cov qauv siv hauv kuv lub tebchaws suav nrog GB/T12459-2005, GB/{15}}, thiab GB/T{16}}.
Kev faib tawm qib siab
Yog tias muab faib los ntawm qib siab, muaj txog kaum xya hom, uas zoo ib yam li Asmeskas cov qauv yeeb nkab, suav nrog: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch0, Sch100, Sch120, Sch140, Sch160, XXS, uas feem ntau siv STD thiab XS.
Raws li lub kaum sab xis ntawm lub luj tshib, muaj 45 degree luj tshib, 90 degree luj tshib thiab 180 degree luj tshib. Nyob rau hauv txoj kev no, muaj ntau hom luj tshib. Thaum kev txiav txim, qhov kev txiav txim feem ntau qhia raws li hauv qab no: xws li "LR STD 90 degree 8", uas txhais tau hais tias 8 "lub luj tshib nrog lub vojvoog ntev, qib siab STD, thiab 90 degree; lwm qhov piv txwv yog, "SR XS 45 degree 4 " sawv cev rau lub vojvoog luv luv, qib siab XS, 45 degree 4" luj tshib. Cov saum toj no yog kev faib tawm dav dav ntawm lub luj tshib. Feem ntau muaj ob hom tees. Peb qhov qhib nrog tib txoj kab uas hla yog hu ua vaj huam sib luag-inch tees. Lub diameters ntawm ob qhov kawg yog tib yam, tab sis txoj kab uas hla ntawm lub converging kawg yog txawv los ntawm lwm yam ob diameters, uas yog hu ua txo tees. Txoj kev qhia yog raws li nram no: Rau qhov sib npaug txoj kab uas hla tees, piv txwv li, ib tug "T3" tee txhais tau hais tias ib tug sib npaug txoj kab uas hla tee nrog ib tug txheej txoj kab uas hla ntawm 3 ntiv tes. Rau kev txo cov tees, piv txwv li, "T4 × 4 × 3.5" txhais tau tias txo cov tee nrog tib txoj kab uas hla li plaub ntiv tes thiab txo txoj kab uas hla ntawm 3.5 ntiv tes. Cov qib siab yog tib yam li lub luj tshib, thiab yog li nws qhov kev qhia tshwj xeeb.
GNEE Steel occupies ib qho chaw nyob rau hauv stainless hlau luj tshib kev lag luam thiab yog ib tug kws nyob rau hauv stainless hlau luj tshib. Koj tuaj yeem pom cov khoom lag luam stainless hlau luj tshib uas ua tau raws li koj xav tau ntawm no.
