Chiyambi cha Chidziwitso Chokwanira Kwambiri Chosindikizira Mafuta

Chiyambi cha Chidziwitso Chokwanira Kwambiri Chosindikizira Mafuta.

Kusindikiza kwamafuta ndi gawo lamakina lomwe limagwiritsidwa ntchito kusindikiza, lomwe limadziwikanso kuti mphete yozungulira ya shaft milomo yosindikiza.Chigawo chotsutsana cha makina chimatetezedwa kuti mafuta asalowe mkati mwa ntchito, ndipo zisindikizo zamafuta zimagwiritsidwa ntchito kuti mafuta asatayike pamakina.Zodziwika bwino ndi zisindikizo zamafuta a mafupa.

1, Njira yoyimira chisindikizo chamafuta

Njira zowonetsera zodziwika bwino:

Mtundu wa chisindikizo chamafuta - m'mimba mwake wamkati - m'mimba mwake - kutalika - zakuthupi

Mwachitsanzo, TC30 * 50 * 10-NBR imayimira chisindikizo chamafuta amilomo iwiri mkati mwa chigoba chokhala ndi mainchesi 30, m'mimba mwake 50, ndi makulidwe a 10, opangidwa ndi mphira wa nitrile.

2, Zinthu za chigoba mafuta chisindikizo

Nitrile rabara (NBR): osavala, osagwira mafuta (sangagwiritsidwe ntchito polar media), osagwira kutentha: -40 ~ 120 ℃.

Hydrogenated nitrile rabara (HNBR): Kukana kuvala, kukana mafuta, kukana kukalamba, kukana kutentha: -40 ~ 200 ℃ (amphamvu kuposa NBR kutentha kukana).

Fluorine zomatira (FKM): asidi ndi alkali kugonjetsedwa, kugonjetsedwa kwa mafuta (kugonjetsedwa ndi mafuta onse), kugonjetsedwa ndi kutentha: -20 ~ 300 ℃ (kutsutsa mafuta kuposa ziwirizi).

mphira wa polyurethane (TPU): Kukana kuvala, kukana kukalamba, kukana kutentha: -20 ~ 250 ℃ (kukana kukalamba kwabwino).

Rabara ya Silicone (PMQ): yosagwira kutentha, yosazizira, yokhala ndi kupindika pang'ono kosatha komanso mphamvu zochepa zamakina.Kutentha kukana: -60 ~ 250 ℃ (zabwino kutentha kukana).

Polytetrafluoroethylene (PTFE): imakhala ndi kukhazikika kwamankhwala abwino, kukana zofalitsa zosiyanasiyana monga asidi, alkali, ndi mafuta, kukana kuvala komanso kukana kutentha kwambiri, mphamvu zamakina apamwamba, komanso zodzikongoletsera.

Nthawi zambiri, zida zomwe zimagwiritsidwa ntchito posindikiza mafuta a mafupa ndi mphira wa nitrile, fluororubber, rabara ya silicone, ndi polytetrafluoroethylene.Chifukwa cha zabwino zodzipaka mafuta, makamaka zikawonjezeredwa ku bronze, zotsatira zake zimakhala zabwino kwambiri.Zonsezi zimagwiritsidwa ntchito popanga mphete zosungira, mphete za Glee, ndi zoyambira.

3, Kusiyanitsa chitsanzo cha mafupachisindikizo cha mafuta

Chisindikizo chamafuta a C-mtundu amatha kugawidwa m'mitundu isanu: mtundu wa chisindikizo chamafuta a SC, mtundu wa chisindikizo cha T Coi, mtundu wamafuta a VC, mtundu wa chisindikizo chamafuta a KC, ndi mtundu wamafuta a DC.Izi ndi zosindikizira zamafuta amtundu umodzi wamkati, zosindikizira zamafuta amilomo iwiri, chisindikizo chamafuta amkati, milomo imodzi yopanda chigoba chamafuta, chisindikizo chamafuta amkati chamilomo iwiri, ndi chisindikizo chamafuta chamkati chamilomo iwiri.(Tikupangira kuti musamalire akaunti yovomerezeka ya "Mechanical Engineer" kuti mumvetse chidziwitso cha zinthu zowuma komanso zambiri zamakampani koyamba)

Chisindikizo chamafuta amtundu wa G-mtundu wamafuta chimakhala ndi mawonekedwe a ulusi kunja, omwe ndi mtundu wofanana ndi C-mtundu.Komabe, zimasinthidwa kuti zikhale ndi mawonekedwe a ulusi kunja kwa ndondomekoyi, mofanana ndi ntchito yaO-ring, zomwe sizimangowonjezera mphamvu yosindikiza komanso zimathandiza kukonza chisindikizo cha mafuta kuti chisamasulidwe.

Chisindikizo chamafuta amtundu wa B chimakhala ndi zomatira mkati mwa chigoba kapena mulibe zomatira mkati kapena kunja kwa chigobacho.Kusakhalapo kwa zomatira kumathandizira kuti ntchito yochotsa kutentha iwonongeke.

Chisindikizo chamafuta amtundu wa A ndi chisindikizo chamafuta chophatikizika chokhala ndi mawonekedwe ovuta kuyerekeza ndi mitundu itatu yomwe ili pamwambapa, yodziwika bwino komanso yothamanga kwambiri.
