Kodi Mungasankhire Bwanji Mafuta Oyenera Pampopi Yanu Ya Hydraulic??

Kugwiritsa ntchito mafuta olakwika a hydraulic ndikupha mwakachetechete pazida zanu. Zimayambitsa kutentha kwambiri, kuvala msanga, ndi kuchita mwaulesi, mwakachetechete kuwononga mpope wanu kuchokera mkati ndi kubweretsa zolephera zosayembekezereka.

Sankhani mafuta anu kutengera ISO mamasukidwe ake kalasi (VG), kwenikweni VG 32 kapena VG 46 kwa mapampu ambiri onyamula. Onetsetsani kuti ili ndi anti-wear (AW) zowonjezera ndikuganizira kutentha kwa ntchito - gwiritsani ntchito kukhuthala kotsika kwa kuzizira ndi kumtunda kwa kutentha.

Nthaŵi ina ndinayendera malo omanga mkatikati mwa nyengo yachisanu ya Minnesota. Ogwira ntchito anali akulimbana ndi pampu ya hydraulic yomwe inali yaulesi kwambiri moti zidalephera kugwiritsa ntchito zida zawo.. Iwo anakhumudwa, poganiza kuti mpope walephera. Ndidayang'ana mafuta omwe amagwiritsa ntchito - anali okhuthala ngati ma molasi pa kutentha kwapansi paziro. Anali mafuta apamwamba kwambiri, koma zolakwika kwathunthu pazikhalidwe. Tinasinthana ndi mafuta a viscosity otsika (ndi VG 22) zomwe timalimbikitsa nyengo yozizira. Chipompelu chamuchiyedi chatela kwikala nawumi, ikuyenda bwino komanso mwamphamvu. Zimene zinachitikazi zinali phunziro lofunika kwambiri: even the best pump in the world can't perform if it's fighting to move oil that has turned to sludge.

Chifukwa chiyani Viscosity ya Mafuta Ndilofunika Kwambiri?

Mukudziwa kuti mumafunikira mafuta a hydraulic, koma manambala osiyanasiyana amasokoneza. Kusankha yolakwika kungapangitse mpope wanu kukhala wodekha kapena wosatetezedwa, and you're not sure which is worse.

Viscosity is the oil's thickness and its resistance to flow. If it's too thick, mpope imalimbana ndi kutentha kwambiri. If it's too thin, imalephera kuthira mafuta bwino, kuchititsa kutha msanga.

Zithunzi za "Goldilocks" Mfundo ya Mafuta

Viscosity ndiye chinthu chofunikira kwambiri pamafuta a hydraulic. Monga injiniya wamakina, Ndimafotokoza kwa makasitomala anga chonchi: you need an oil that's "just right." Kwa woyang'anira zokonza ngati Michael, izi zikutanthauza kusankha mafuta omwe ndi ochepa kwambiri kuti azitha kuyenda mosavuta polowera pompo (kupewa cavitation) koma wandiweyani wokwanira kupanga amphamvu, filimu yoteteza pakati pa zigawo zachitsulo zosuntha. Filimuyi ndi yomwe imalepheretsa kuvala ndi kung'ambika. Ambiri opanga, kuphatikiza LONGLOOD, tchulani Gulu la ISO Viscosity (VG) kwa mapampu awo. Kwa mapampu amphamvu-zambiri, izi nthawi zambiri VG 32 kapena VG 46. Ganizirani za manambalawa ngati muyeso wokhazikika wa makulidwe pa kutentha kwina (40°C). Sticking to the manufacturer's recommended VG is the safest way to ensure your pump has the right balance of flowability and protection for its designed operating conditions.

Kodi Kutentha Kumakhudza Bwanji Kusankha Kwanu Mafuta??

Pampu yanu imagwira ntchito bwino m'mawa koma imakhala yaulesi komanso yofooka masana kutentha. Kusagwirizana kokhumudwitsa kumeneku kumachepetsa ntchitoyo ndikukupangitsani kukayikira kudalirika kwa zida zanu.

Kutentha kumapangitsa mafuta kukhala ochepa, kuchepetsa mamasukidwe ake akayendedwe ndi zoteteza katundu. Kuzizira kumapangitsa kuti mafuta achuluke, kuwonjezera mamasukidwe ake akayendedwe ndi njala mpope. Sankhani mafuta kutengera anu ogwira ntchito kutentha, osati nyengo yokha.

Viscosity Si Nambala Yokhazikika

A critical mistake I see people make is forgetting that an oil's viscosity changes dramatically with temperature. Nambala ya ISO VG ndi chithunzithunzi chabe pa 40°C. Pamene mpope ikuyenda, zimapanga kutentha. Pamene mafuta akutentha, zimaonda. Ngati iwowonda kwambiri, filimu yoteteza pakati pa zigawo zimatha kusweka, kutsogolera kukhudzana ndi zitsulo pazitsulo ndi kuvala mofulumira. Ichi ndichifukwa chake m'malo otentha kapena ntchito zothamanga kwambiri, mafuta ochepa kwambiri ngati VG 46 ikhoza kukhala chisankho chabwino kuposa VG 32. Chosiyana ndi chowona m'nyengo yozizira. ndi VG 32 mafuta amatha kukhala wandiweyani kwambiri kuti asayende bwino, kutsogolera ku vuto lenileni la njala ndi cavitation zomwe ndinaziwona pamalo omanga achisanu. Muzochitika izi, mafuta otsika mamasukidwe oyenera. Kwa zida zomwe zimagwiritsidwa ntchito m'malo okhala ndi kutentha kwakukulu, mafuta a hydraulic amitundu yambiri okhala ndi Viscosity Index yayikulu (VI) ndi yankho lalikulu, popeza imasunga kukhuthala kokhazikika pamtunda wotalikirapo wa kutentha.

Ndi Mafuta Otani Amene Muyenera Kugwiritsa Ntchito?

Kulowa m'sitolo, you're faced with a wall of different hydraulic oils. Onse amawoneka ofanana. Kusankha yolakwika kungatanthauze kutaya chitsimikizo kapena kuwononga pampu yanu yodula.

Gwiritsani ntchito mafuta apamwamba kwambiri opangidwa ndi mineral-based hydraulic okhala ndi "AW" (anti-kuvala) phukusi zowonjezera, kufananiza ndi ISO VG yolimbikitsidwa ndi wopanga mpope. Kwa zida zambiri za LONGLOOD, izi ndi AW 32 kapena AW 46.

Khalani Osavuta Komanso Apamwamba

Ngakhale pali madzi ambiri ovuta komanso opangira ma hydraulic pamsika, kwa ambiri ntchito mafakitale, you don't need to overthink it. Muyezo, mapangidwe apamwamba, mafuta opangidwa ndi mineral-based hydraulic mafuta ndiye gawo lalikulu pamsika. Chofunikira kwambiri chomwe muyenera kuyang'ana ndi "AW" dzina. Izi zikutanthauza kuti mafuta ali ndi phukusi lowonjezera lomwe limapangidwira kuteteza mpope kuti zisavale pansi pa zovuta kwambiri zomwe zimapezeka m'makina athu. Zowonjezera izi, ngati zinc, kupanga wosanjikiza nsembe pa zitsulo pamwamba. When you stick to a reputable brand and the manufacturer's recommended viscosity grade (ngati AW 32 kapena AW 46), mutha kukhala otsimikiza kuti mukupereka chitetezo choyenera cha mpope wanu. Pewani chiyeso chogwiritsa ntchito mafuta agalimoto, kutumiza madzimadzi, kapena mafuta ena omwe si a hydraulic. They don't have the right properties and will cause damage.

Quick Recommendation Guide:

• Kugwiritsa Ntchito Mwachizoloŵezi (50F mpaka 95°F / 10°C mpaka 35°C): ISO VG 32 Anti-Wear (AW 32) Mafuta a Hydraulic.
• Kwa Malo Otentha (>95° F / 35°C): ISO VG 46 Anti-Wear (AW 46) Mafuta a Hydraulic.
• Kwa Malo Ozizira (<50° F / 10°C): ISO VG 22 Anti-Wear (AW 22) Mafuta a Hydraulic.

Mapeto

Kusankha mafuta oyenera a hydraulic ndikosavuta: match the manufacturer's recommended viscosity grade (ngati VG 32/46), onetsetsani kuti ili ndi zowonjezera zowonjezera, ndikusintha kutentha kwambiri kuti muwonetsetse kudalirika kwapompu kwanthawi yayitali.
