Nyob rau hauv pneumatic tswj systems, ib tug longstanding engineering teeb meem tshwm sim: yog aob- thooj cua npaj chav tsevtxaus, los yog apeb -piece unityuav tsum tau?
Junior designers feem ntau hais txog peb -thooj units los ntawm lub neej ntawd, piv txwv li "cov khoom siv ntau dua txhais tau tias muaj kev ntseeg siab dua." Rau cov kws paub txog engineers, qhov kev xaiv tsis xav no qhia txog kev txiav txim siab engineering tsis txaus.
Tsis yog kev cia siab rau cov rooj xaiv dav dav, tsab xov xwm no txheeb xyuas qhov sib txawv tseem ceeb ntawm ob qhov kev teeb tsa no los ntawm cov hauv paus ntsiab lus thiab cov qauv kev lag luam tam sim no, tsom mus rau pneumatic system chav npaj huab cua.
FRL Fundamentals
Hauv qabTS EN ISO 1219-1 Cov cim kos duab rau cov tshuab pneumatic thiab cov khoom siv, ob qho tib si configurations yog thoob ntiaj teb hu uaFRL units:
- F: Lim
- R: Regulator
- L: Lubricator
- Peb -piece unit: Integrated Filter + Regulator + Lubricator
- Ob -piece unit: Combined Lim + Regulator nkaus xwb
Qhov sib txawv yog ntau dua li cov khoom sib xyaw: tshem lub lubricator sawv cev rau kev hloov pauv mus rau roj -pneumatic thev naus laus zis.
Core txawv
1. Muaj nuj nqi Distinction (GB/T 14513-2021)
- Peb -piece unit: Muablubricated compressed cua, muab kev pom, kev tswj xyuas siab, thiab roj pos huab (1-3 μm particle loj) rau cov khoom qis qis.
- Ob -piece unit: Muabqhuav, roj-dawb compressed cua, tshem tawm particulates thiab condensate yam tsis muaj lubrication.
2. Kev tsim qauv tsim
Thaum ntxov peb -thooj units siv discrete series- txuas txuas. Niaj hnub no ob -thooj units txais yuavmodular, stackable tsimrauISO 11727 Kev Tswj Xyuas, feem ntau integrating lim thiab regulator rau hauv ib lub lim-regulator los ua ke kom txo tau cov ntsiab lus to thiab yooj yim installation.
Qhov nce ntawm ob -Pib Chav: Roj-Pneumatics dawb
Cov ntawv thov siab- kawg suav nrog cov khoom siv hluav taws xob, kev ua zaub mov thiab tshuaj tsuas yog siv ob-thooj units, uas tau tsav los ntawm kev lag luam hloov mus rau roj- ua haujlwm dawb.
Cov khoom siv pneumatic niaj hnub los ntawm cov tuam txhab ua lag luam (SMC, Festo, thiab lwm yam) siv tus kheej - lubricating seals thiab ua ntej - lubricated bearings nrog lub Hoobkas- puv ntev - roj roj, tshem tawm qhov xav tau rau huab cua huab cua.
Raws liJB/T 5967-2021, roj pos huab lubricator yogtxwv tsis pubnyob rau hauv cov tshuab siv roj-dawb lossis tus kheej-lubricating Cheebtsam, raws li cov roj ntau dhau ua rau cov pa roj carbonized sludge uas tuaj yeem txhaws lossis txeeb cov khoom sib npaug thiab kev tswj xyuas qhov tseeb.
Daim ntawv thov Profiles
Ob -Piece Unit
- Nta: Kev ua haujlwm siab, huv si, qis- tu
- Daim ntawv thov: Precision electronics, cov cuab yeej kho mob, laser cutters, cov khoom siv hluav taws xob tshiab
- Lub hauv paus ntsiab lus: Cia siab rau kev tsim- nyob rau hauv cov khoom siv lubrication, tsis txhob muaj kab mob hauv huab cua
Peb -Piece Unit
- Nta: Muaj zog, hnav- tiv thaiv, txij nkawm- hnyav
- Daim ntaub ntawv: Woodworking machinery, pneumatic cov cuab yeej, tsoos forging khoom
- Lub hauv paus ntsiab lus: Cov roj tsis tu ncua lubrication thiab txias rau pneumatic lub cev muaj zog thiab cuam tshuam lub tog raj kheej
Flow Performance: Siab poob
IbTS EN ISO 6358 Cov, txhua qhov sib xyaw ua ke qhia txog kev poob siab.Peb -cov khoom feem ntau xa tuaj10% - 20% qis dua rated flowdua li qub-chaw nres nkoj- loj ob- thooj units vim qhov ntxiv ntws tsis kam ntawm lub lubricator.Nyob rau hauv siab -flow systems nrog loj - bore cylinders, undersized peb -piece units yuav ua rau qeeb, underpowered actuation.
Kev Kho Kom Zoo
- Ob -piece unit: Tsom ntsoov rau cov kua dej condensate; ntau cov qauv txhawb nqa tsis siv neeg tso dej.
- Peb -piece unit: Yuav tsum tau cov kua dej condensate ntxiv rau cov roj li niaj zaus - saib xyuas qib thiab drip - tus nqi hloov kho (1-5 tee / min). Tsuas yogISO VG 32 turbine rojtso cai; cav roj tsis pub.
Xaus
Qhov sib txawv tseem ceeb nyob hauvLub luag hauj lwm ntawm lubrication:
- Ob -cov khoom tso siab rau niaj hnub, kev saib xyuas-dawb tus kheej- lubricating Cheebtsam.
- Peb -cov khoom siv siv cov roj pos huab los txo kev sib txhuam thiab hnav.
Kev xaiv yuav tsum yog raws li qhov tseeb actuator lubrication cov cai, tsis yog qhov tshwj xeeb. Nyob rau hauv lub sijhawm ntawm cov roj-kev tsim khoom dawb thiab huv si, txhob txwm ua kom yooj yim feem ntau ua rau pom kev ua haujlwm siab dua li kev tsim kho dua tshiab.
