NPT thiab nws tus yam ntxwv

Ua steel pas nrig los yog lub raj los ntawm ua threading ib tug tshwj xeeb uas hu ua ib tug threaded kev twb kev txuas. Nws yog siv rau cov neeg rau, screws, bolts, uas yog ces siv mus txuas rau ntau yam thiab cov rooj sib txoos, thiab cov yeeb nkab xov yog siv los pipeline installation.

Lub ntsiab ntsiab ntawm no hom ntawm detachable compound yog nws suab, profile, qhov tob ntawm lub grooves thiab lub lub cheeb ntawm lub sab nraud thiab sab hauv. Profiles raug muab faib ua ob peb hom: Trapezoidal, voos, lub thiab lwm tus neeg. Yuav ua li cas yog ib tug profile? Yog hais tias peb ua ib tug ntoo khaub lig-section, ces tau txais ib daim ntawv thiab muaj ib tug profile.

Nrhiav rau dab tsi lub hom phiaj, qhov khoom yuav siv tau rau cov yeeb nkab xov yuav tsum yog sab laug los yog txoj cai. Tsis tas li ntawd, nws yuav tsum tau muab faib mus rau hauv tshwj xeeb thiab dunnage.

Lub ntsiab yam kev kho tebchaw yog ib cov voos profile, thiab tshwj xeeb kev sib txuas - rectangular, thiab ib tug xov tooj ntawm lwm yam kev profiles.

Carving, wrought rau lub screws, bolts, ceev - daim duab peb sab, vim hais tias nws yog siv rau fasteners. Qhov kev ncua deb ntawm crests los yog troughs ntawm ob bases lem ze hu ua kauj ruam. Lub qhov tob ntawm xws li ib tug compound yog qhov kev ncua deb ntawm lub hauv qab mus rau saum taw tes ntawm lub kauj.

Kho yeeb nkab xov los yog voos, yog nti thiab metric. Feem ntau, nws yog cov thawj fasteners nyob rau hauv lub tsheb ntsuas. Diameters, ob sab hauv thiab sab nraud, yog ntsuas nyob rau hauv millimeters, thiab threaded kauj ruam, tsuas yog millimeters, txawm nyob rau hauv nws cov shares.

Tab sis yeeb nkab inch xov muaj ib tug kaum sab xis ntawm 55 degrees, txawm hais tias tus profile yog tib yam li hais tias ntawm lub metric. Lawv txawv yog hais tias cov kev ntsuam tshwm sim nyob rau hauv nti es millimeters vim lub loj suab.

Thaum txhim kho kav dej kav dej uas siv thiab qhov chaw nrog ib tug threaded nti. Nws yog fastening thiab cov yeeb nkab. Nyob rau cov kav dej nyob rau hauv view ntawm lub fact tias nws tob yog tswj los ntawm lub thickness ntawm cov yeeb nkab phab ntsa, me threads. Tab sis kuj vim ib tug ntau dua tus naj npawb ntawm lem - ib tug tighter kev twb kev txuas. Tab sis rau ib tug ruaj khov tebchaw haum ru tsev kho xov, uas, raws li tau teev los saum no, txiav mus rau hauv bolts, screws, ceev, ua los ntawm cov khoom hlau.

Kho yeeb nkab xov, nyob rau hauv tas li ntawd mus tsis siv neeg tej, nws muaj peev xwm yuav txiav manually nrog rau kev siv tsuav. Daim Hlau tau tseem muab faib mus rau hauv hom, nyob ntawm seb lawv ntaus ntawv. Lawv yog cov prismatic, puag ncig, zawv zawg thiab tag nrho.

Piv txwv li, zawv zawg lub hnub, tej tag nrho cov xov yuav tiv thaiv tau me me variations txoj kab uas hla nws yog xim hlau pas nrig. Thov tag nrho cov round hnub, hloov nyob rau hauv txoj kab uas hla twb tsis tsim nyog.

Threaded rau cov yeeb nkab raws li nram no: nws yog tsim nyog los tuav lub mas nruab thiab luag tus workpiece, thiab siv yeej tuag, kom dhau lub tswv yim npaj ntev ntawm ib lub sij hawm. Yog hais tias muaj yog siv zawv zawg phiaj, cov txiav yuav muab qhov chaw nyob rau hauv ob los yog peb dhau mus.

Thaum tej lub cai ntsia hlau kev twb kev txuas tuag Tshuag yuav tsum tau tig mus rau sab xis thiab sab laug nyob rau tej - mus rau sab laug, thaum tsis nco qab mus ua ib tug ob peb lem rov qab rau kev tshem tawm. Thaum txhua yam yog npaj txhij, nws yuav tau xyuas nrog kev pab los qhwv ceev.

Nyob rau hauv tus txheej txheem ntawm tej lub steel yeeb nkab xov hais thiab nws tus kheej rhuab tuag. Rau lawv siv sulfofrezol txias los yog so roj. Rau txias ntawm cam khwb cia hlau yog zoo tshaj plaws haum Turpentine.

Lub sab hauv coils yog txiav kais. Nyob rau hauv tib txoj kev uas nws yog fastened nyob rau hauv lub tuav ib feem, thiab muaj ib tug thawj kais qhov yog tas suav. Tom qab tshem tawm ntawm ib tug hlau txheej, thov ib tug thib ob thiab thib peb ub, txiav twb puv puv. Yuav kom paub tseeb tias qhov tseeb hais tias lub axis ntawm tus kais qhov thiab lub match. Los ntawm lub sij hawm rau lub sij hawm, qhib tus kais nyob rau hauv kev coj rov qab ¼ tig mus rau tshem tawm cov chips.
