Thaum tsim los yog tswj lub hauv nruab nrab lubrication system, 90% ntawm cov xim mus rau lub twj tso kua mis. Txawm li cas los xij, lub twj tso kua mis tsis muaj txiaj ntsig yog tias lub roj nplua nyeem tsis tuaj yeem ncav cuag cov kabmob. Cov raj thiab fittings - cov hlab ntsha thiab cov hlab ntsha ntawm koj lub tshuab - yog ib qho tseem ceeb. Ib lub kinked hose, lub tes tsho compression crushed, los yog ib qho txuas txuas tuaj yeem ua rau lub siab poob siab uas tshaib plab tag nrho lub cev, ua rau lub tshuab tsis ua haujlwm.
Ntawm Ishan Precision, peb muab tsis yog lub twj tso kua mis xwb, tab sis tag nrho cov ecosystem ntawm lubrication hardware. Nyob rau hauv phau ntawv qhia no, peb yuav dhia mus rau qhov feem ntau -overlooked ntiaj teb no ntawm siab - siab tubing, compression fittings, thiab installation cov kev coj zoo tshaj plaws. Txawm hais tias koj tab tom kho qhov xau los yog kav lub tshuab tshiab los ntawm kos, qhov no yog qhov koj yuav tsum paub.
Xaiv txoj cai Tubing Khoom: Nylon, Tooj, lossis Hlau?
Tsis yog txhua lub raj yog tsim sib npaug. Ib puag ncig ntawm koj lub tshuab dictates cov khoom koj yuav tsum siv. Kev siv cov tubing tsis raug yog qhov # 1 ua rau rov ua dua.
1. Siab -Nylon Tubing (Cov Qauv Kev Lag Luam)
Rau 80% ntawm kev siv CNC,Nylon 12 (PA12)tubing yog cov khoom ntawm kev xaiv.
Pros:Saj zawg zog, yooj yim rau txoj hauv kev los ntawm txoj hlua rub, tiv taus kev co qaug zog, thiab cov lus translucent (tso cai rau koj pom cov roj ntws).
Cons:Muaj peev xwm yaj yog raug kub hlau chips; kev ntsuas qis dua li hlau.
Qhov zoo tshaj plaws rau:Txuas cov khoom txav (xws li lub eeb lossis ntoo khaub lig-slide) thiab cov kav dej dav dav hauv lub txee.
Specs:Qhov ntau thiab tsawg yog 4 hli (OD) thiab 6 hli (OD). Nco ntsoov xyuas kom cov tubing raug ntsuas tsawg kawg yog 25 kgf / cm² rau cov tshuab roj.
2. Copper lossis Aluminium Tubing
Pros:Thaum tshav kub kub resistant, tuav nws cov duab rigidly (tsis sag), tsis tshua muaj zog.
Cons:Nyuaj rau nruab (yuav tsum tau khoov cov cuab yeej); nquag ua hauj lwm- hardening thiab cracking nyob rau hauv hnyav vibration.
Qhov zoo tshaj plaws rau:Cov kab zoo li qub uas khiav raws lub hauv paus casting, los yog thaj chaw raug kub chips thiab coolant txaws.
3. Siab-Hloov roj hoses
Rau hnyav-cov roj ua haujlwm (txhaj tshuaj molding, excavators), tus qauv nylon yuav tawg. Koj xav taureinforced hosenrog ib tug hluavtaws roj hmab core thiab fiber braiding.
Specs:feem ntau ntsuas rau 200+ kgf/cm² (3000 PSI).
Qhov zoo tshaj plaws rau:Txuas lub twj tso kua mis mus rau lub ntsiab distributor, lossis rau cov kab hloov pauv ntawm cov xovxwm hnyav.
Nkag siab Compression Fittings: Txoj Cai "Olive".
Yuav luag txhua lub tshuab lubrication sivCompression Fittings. Tsis zoo li cov kav dej hauv tsev uas tej zaum yuav siv Teflon daim kab xev los yog kua nplaum, cov fittings no cia siab rau txhua yam deformation los tsim lub foob.
Peb lub hauv paus tseem ceeb yog:
Txiv Neej:Screws rau ntawm qhov chaw nres nkoj.
Lub Tes Tsho (Olive/Ferrule/Bushing):Ib lub nplhaib me me los yog txhuas lub nplhaib uas swb hla lub raj.
Insert (Stiffener):Ib lub raj me me hlau uas mussab hauvcov nylon tubing los tiv thaiv nws los ntawm kev sib tsoo.
Nws ua haujlwm li cas:Thaum koj ceev cov txiv ntoo, nws compresses lub "Olive" tiv thaiv tubing. Cov txiv ntseej deforms, tom rau hauv lub raj thiab tsim kom muaj kev ruaj ntseg, siab - lub foob foob.
Txoj Cai Tseem Ceeb:Tsis txhob omit lubNtxigthaum siv nylon tubing. Yog tsis muaj qhov ntxig, lub zog compression yuav tsoo lub raj yas hollow, ua rau kev sib txuas kom xoob thiab xau tsis pub dhau hnub.
Kauj ruam-los ntawm- Cov kauj ruam Installation Guide: Yuav ua li cas tiv thaiv Leaks
Kev xau- qhov system dawb pib nrog cov txheej txheem kev teeb tsa kom raug. Nov yog cov txheej txheem peb cov kws kho mob siv:
Kauj Ruam 1: Txiav
Siv ib qho tshwj xeebTube Cutter(guillotine style). Tsis txhob siv sab cutters, pliers, lossis txiab.
Vim li cas? Pliers tsoo lub raj rau hauv ib qho oval. Ib lub raj oval yuav tsis muab khi rau ntawm cov txiv ntseej puag ncig. Koj xav tau ib tug zoo meej 90-degree, ncig txiav.
Kauj Ruam 2: Kev sib dhos
Swb lubTxiv ntseejrau lub cev. Ces swb lubTxiv ntseejntawm. Thaum kawg, thawb lubNtxigtag nrho rau hauv qhov kawg ntawm lub raj.
Tswv yim: Yog hais tias lub raj yog txhav, dipped qhov kawg hauv cov roj sov kom tso cov stiffener yooj yim dua.
Kauj Ruam 3: Tshem Tawm
Thawb lub raj rau hauv qhov chaw nres nkoj kom txog thaum nws tsoo hauv qab (tus "lub xub pwg nyom"). Tuav nws kom ruaj khov. Yog tias lub raj rub rov qab txawm tias 1 hli thaum lub sijhawm nruj, lub foob tuaj yeem tsim ntawm qhov chaw tsis raug, tsim kom muaj kev sib koom ua ke tsis muaj zog (qhov "tuag ntim" cheeb tsam).
Kauj Ruam 4: Tightening
Tighten lub txiv ntoo ntawm tes kom txog thaum nws snug. Tom qab ntawd, siv tus ciaj ntswj kom nruj nws ntxiv.
Rau Nylon: Feem ntau 1.5 mus rau 2 puv puv.
Rau tooj liab: Feem ntau 3/4 rau 1 tig.
Lus Ceeb Toom: Tsis txhob dhau - nruj. Yog tias koj crank nws nyuaj heev, koj tuaj yeem tawg cov txiv ntseej tooj dag lossis txiav cov xov. Thaum cov txiv ntseej tawg lawm, nws tsis tuaj yeem rov siv dua.
Hom xov: M8, M10, PT, lossis NPT?
Thaum txiav txim hloov fittings, koj yuav tsum txheeb xyuas cov xov hom ntawm koj lub tshuab lossis distributor block. Qhov no feem ntau yog qhov tsis meej pem rau cov neeg yuav khoom.
Metric (M8x1, M10x1):Tus qauv rau Ishan, Showa, thiab feem ntau Asian / European tshuab. Nco ntsoov tias M8x1 yog cov xov zoo, txawv ntawm tus qauv ntxhib M8 ntsia liaj qhov rooj koj yuav ntawm lub khw muag khoom kho vajtse.
PT (BSPT / R):British Standard Yeeb Nkab Taper. Feem ntau nyob rau hauv cov laus Japanese thiab Taiwanese machinery. Nws muaj ib tug tapered xov uas seals thaum koj zawm nws. (eg, 1/8 PT).
NPT:National Pipe Taper. Tus qauv American.Nco tseg:PT thiab NPT tsis sib xws. Lub kaum sab xis yog txawv (55℃vs 60 degree). Kev quab yuam NPT haum rau hauv PT lub qhov yuav ua rau lub manifold puas.
Yog tias koj tsis paub meej, Ishan Precision muab cov khoom siv xov tooj thiab cov khoom siv sib txuas (piv txwv li, M10 txiv neej rau 1/8 PT poj niam) los daws cov teeb meem kev sib raug zoo.
Kev daws teeb meem: Vim li cas kuv lub Fitting Leaking?
Yog tias koj pom cov roj ntws los ntawm kev sib txuas, xyuas peb tus neeg ua txhaum cai no:
Qhov "Missing Insert" yuam kev:Muab qhov sib cais. Yog hais tias lub nylon raj zoo li crushed los yog flattened, lub installer yuav tsis nco qab qhov kev txhawb nqa insert. Txiav cov seem uas puas lawm thiab reinstall nrog ib tug tshiab ntxig thiab txiv ntseej.
Qhov "Reuse" yuam kev:Compression txiv ntseej yog ib qho - siv cov khoom. Thaum deformed, lawv tsis tuaj yeem compressed dua. Yog tias koj tshem lub raj, koj yuav tsum ua tib zoo txiav lub nplhaib qub thiab nruab ib lub tshiab.
Vibration Loosening:Ntawm - nrawm nrawm nrawm, kev co tuaj yeem rov qab lub txiv ntoo tawm. Siv ib lub dab ntawm qhov nruab nrab- lub zog xov xauv (Loctite Blue) ntawm cov txiv ntoo xov (tsis txhob nyob hauv txoj kev ua kua) lossis siv cov xim pleev xim rau "torque mark" cov txiv ntoo kom koj tuaj yeem pom qhov pom tau tias nws tau txav mus los.
Xaus: Tsis txhob hla ntawm Hardware
Nws yog ntxias mus yuav pheej yig, generic fittings kom txuag tau ob peb duas las. Tab sis xav txog qhov no: $ 2 haum uas tsis tuaj yeem tso koj lub twj tso kua mis $ 500 thaum hmo ntuj, tsim kom muaj roj ntau ntawm koj lub khw hauv pem teb thiab khiav koj $ 100,000 CNC tshuab qhuav.
Koj lub lubrication system yog siab - hydraulic circuit. Nws thov kev hwm. Los ntawm kev siv tiagIshan siab - siab tubing thiab fittings, thiab ua raws li cov txheej txheem kev teeb tsa kom raug, koj xyuas kom meej tias txhua qhov poob ntawm cov roj them los ntawm lub twj tso kua mis tau ncav cuag cov kabmob uas xav tau.
