NPT (National Pipe Taper) hydraulic fittings yog dav siv nyob rau hauv ntau yam lag luam los tsim kom muaj kev sib txuas ntawm cov kav dej thiab lwm yam hydraulic.Kev sib khi cov fittings no yog ib qho tseem ceeb heev los xyuas kom meej tias kev ua tau zoo thiab tiv thaiv cov kua dej tawm, uas tuaj yeem ua rau muaj nqi qis thiab muaj peev xwm txaus ntshai.
Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm kev sib khi NPT hydraulic fittings thiab muab cov lus qhia ib kauj ruam los ntawm kauj ruam yuav ua li cas thiaj li ua tiav kev ruaj ntseg thiab txhim khu kev qha.
Dab tsi yog NPT Hydraulic Fittings?
NPT khoomyog tus cwj pwm los ntawm lawv cov tapered threads, uas tsim ib lub foob nruj raws li lawv tau nruj.Cov threads yog tsim los sib sib zog nqus, ua rau lawv zoo tagnrho rau cov ntawv thov siab.Cov fittings no feem ntau siv nyob rau hauv hydraulic systems, roj kab, thiab pneumatic daim ntaub ntawv.
Qhov tseem ceeb ntawm kev sib khi zoo
NPT kaw kom raug fittings yog qhov tseem ceeb rau ntau yam:
Tiv thaiv cov kua dej tawm
Hauv cov tshuab hydraulic, txawm tias qhov xau tsawg tshaj plaws tuaj yeem ua rau poob qis hauv kev ua haujlwm thiab kev ua haujlwm.
Ua kom muaj kev nyab xeeb
Hydraulic cov kua dej xau tuaj yeem ua rau qhov chaw nplua, ua rau muaj kev pheej hmoo ntawm cov neeg ua haujlwm.
Zam Kev Tiv Thaiv Kab Mob
Leaks tuaj yeem qhia cov kab mob sib kis rau hauv hydraulic system, uas ua rau muaj kev puas tsuaj rau cov khoom rhiab heev.
Txhim khu kev ua tau zoo
Lub kaw lus kaw zoo ua kom lub zog hydraulic ua haujlwm ntawm nws lub peev xwm zoo.
Yuav ua li cas koj kaw NPT threads kom zoo?
Txhawm rau kaw NPT xov zoo, ua raws cov kauj ruam no:
Kauj Ruam 1: Ntxuav Cov Xov
Xyuas kom cov xov ntawm ob qho tib si haum thiab cov mating tivthaiv yog huv si thiab tsis muaj khib nyiab, av, los yog qub sealant residues.Siv cov tshuaj ntxuav kom haum thiab txhuam txhuam yog tias tsim nyog.
Kauj Ruam 2: Siv lub sealant
Xaiv cov xov zoo zoo uas haum rau koj daim ntawv thov hydraulic tshwj xeeb.Siv lub sealant rau txiv neej threads ntawm qhov haum.Ceev faj tsis txhob siv ntau dhau, vim tias cov sealant ntau dhau tuaj yeem mus rau hauv lub tshuab hydraulic.
Lus Cim: Teflon daim kab xev los yog lwm yam ntaub ntawv sealing kuj siv tau los muab koj cov xov.
Kauj Ruam 3: Sib sau cov Fittings
Ua tib zoo xov NPT haum rau hauv cov khoom sib txuas los ntawm tes.Qhov no ua kom cov xov sib raug zoo thiab txo qhov kev pheej hmoo ntawm kev hla xov.
Kauj Ruam 4: Tighten cov kev sib txuas
Siv cov ciaj ntswj tsim nyog, ceev cov fittings kom nruj tab sis tsis txhob nruj dhau, vim nws tuaj yeem ua rau cov xov los yog qhov haum nws tus kheej.Over-tightening kuj tseem tuaj yeem ua rau lub foob tsis sib xws.
Kauj Ruam 5: Tshawb xyuas cov Leaks
Tom qab zawm cov fittings, tshuaj xyuas tag nrho cov kev sib txuas rau txhua qhov cim qhia txog kev xau.Yog tias pom muaj cov dej xau, disassemble qhov kev sib txuas, ntxuav cov xov, thiab rov qab siv lub sealant ua ntej reassembled.
Feem ntau yuam kev kom zam
➢Kev siv cov sealant tsis raug rau cov kua dej hydraulic siv.
➢Kev siv ntau dhau los yog tsis siv cov sealant, ob qho tib si tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm lub foob.
➢Tsis quav ntsej los ntxuav cov xov kom huv si ua ntej thov sealant.
➢Over-tightening cov fittings, ua rau puas threads thiab tej zaum yuav xau.
➢Tsis tuaj yeem kuaj xyuas cov dej xau tom qab sib dhos.
Xaiv Txoj Cai Sealant rau NPT Fittings
Qhov kev xaiv ntawm sealant nyob ntawm seb yam xws li hom hydraulic kua, kev khiav hauj lwm siab, thiab kub.Nws yog ib qho tseem ceeb los sab laj cov neeg tsim khoom cov lus pom zoo thiab xaiv cov sealant uas ua tau raws li cov kev cai tshwj xeeb ntawm hydraulic system.
Lub tswv yim rau Kev Tswj Xyuas NPT Fittings
➢Tsis tu ncua xyuas cov fittings rau cov paib ntawm cov pa xau los yog kev puas tsuaj.
➢Hloov cov khoom puas los yog hnav kom sai.
➢Ua raws li hydraulic system txoj kev npaj kho kom zoo.
➢Qhia cov neeg ua haujlwm los tuav thiab sib sau NPT fittings kom raug.
Qhov Zoo ntawm Kev Siv NPT Fittings
NPT fittings muaj ntau yam zoo:
➢Ib qho yooj yim installation vim lawv tapered threads.
➢Versatility nyob rau hauv ntau yam kev siv.
➢Muaj peev xwm los tswj cov kev kub ntxhov ib puag ncig zoo.
➢Muaj nyob rau hauv ntau yam ntaub ntawv kom haum rau cov kev khiav hauj lwm sib txawv.
