Mafuta opangira zinthu zambiri amatha kuphimba ntchito zambiri zomwe zimapangitsa kukhala kofunikira pakuchepetsa katundu ndi ndalama zomwe zimagwirizana, komanso kufewetsa pulogalamu yamafuta.Nthawi zambiri, mafuta opangira zinthu zambiri amakhala ndi lithiamu wokhuthala ndipo amakhala ndi zowonjezera za Antiwear (AW) ndi/kapena Extreme Pressure (EP) ndi mafuta oyambira okhala ndi viscosity kuyambira SAE 30 mpaka SAE 50.

Koma mafuta opangira zinthu zambiri sangathe kugwira ntchito zonse m'mafakitale.Kuti timvetsetse mafuta, tiyenera kuyang'ana pakupanga mafuta.Mafuta amapangidwa ndi zinthu zitatu;masheya kapena masheya, chokhuthala ndi zowonjezera.

Poganizira zamafuta, zinthu zonse zomwe muyenera kuziganizira ndizo;

• Grease Thickener Type
• Base Fluid Type
• Base Fluid Viscosity
• Zowonjezera Zofunikira
• Gawo la NLGI

Komanso lingalirani za chilengedwe cha ntchito.Kutentha kozungulira ndi malo ogwiritsira ntchito ndizofunikira kuti muwone momwe mafutawo ayenera kukhalira.Malo onyowa ndi fumbi zimafunikira kubwereza pafupipafupi kuti zinthu izi zisamaipitsidwe.Ganiziraninso za kutentha kwa ntchito ndi kukonzanso mayendedwe kuti mudziwe bwino mankhwala oti mugwiritse ntchito komanso njira yabwino yogwiritsira ntchito mafuta.Malo akutali kapena ovuta kufikako pangani malo opangira mafuta odzipangira okha.Kuchokera pamtundu wamafuta oyambira komanso mawonekedwe a viscosity, kutentha kwakukulu kuyenera kuphatikizidwa muzosankha zamafuta oti asankhe.

Mafuta okhuthala ndi ochulukirapo ndipo ena ali ndi mawonekedwe apadera komanso maubwino.Mitundu ina ya thickener imatha kuwonjezera magwiridwe antchito kumafuta.Mwachitsanzo, kukana madzi kumatha kukhala bwino mukamagwiritsa ntchito aluminium complex kapena calcium complex thickeners.Pali mwayi wotentha womwe ma thickeners ena amakhala nawo kuposa ena.Kugwirizana kwa Thickenerndizodetsa nkhawa kwambiri.PaliMa chart a Thickener Compatibilitykupezeka kuti muganizidwe, koma njira yabwino ndikufunsana ndi omwe akukugulirani kuti muwone ngati ayesapo kuyesa kufananiza ndi mitundu yosiyanasiyana ya thickener.Ngati sichoncho, kuyezetsa kufananira kwamafuta kumatha kuyendetsedwa ndi madola mazana angapo kuti muwonetsetse kuti sagwirizana.

Mafuta oyambira omwe amagwiritsidwa ntchito mumafuta nthawi zambiri amakhala mafuta amchere, zosakaniza zopangira kapena zopangira zonse.Mafuta opangidwa ndi polyalphaolefin (PAO) amagwiritsidwa ntchito pafupipafupi, chifukwa amagwirizana ndi mafuta amchere amchere.Madzi ena opangira mafuta omwe amagwiritsidwa ntchito popanga mafuta ndi monga esters, silicone fluid, Perfluoropolyethers, ndi zina zopangira ndi zophatikizika.Kachiwiri, ngakhale
zoyambira zogwiritsidwa ntchito mumafuta osiyanasiyana sizotsimikizika.Yang'anani deta yomwe imapanga mafuta kuti muwone ngati ikunena zamtundu wamafuta.Ngati mukukayikira, funsani wothandizira kuti mudziwe zambiri za mtundu wa madzimadzi oyambira omwe amagwiritsidwa ntchito mu girisi.Yang'anani ngati ikugwirizana ndi madzi oyambira omwe amagwiritsidwa ntchito mumafuta omwe akugwira ntchito pano.Kumbukirani kutiViscosity yamadzimadzi oyambira omwe amagwiritsidwa ntchito mumafuta amayenera kufananizidwa moyandikira kwambiri ndi zomwe zimafunikira pa liwiro, katundu ndi kutentha kwa ntchitoyo..

Zowonjezera zomwe zimaphatikizidwa mumafuta nthawi zambiri zimakhala ndi antioxidants, dzimbiri ndi corrosion inhibitors, ndi antiwear kapena pressure pressure (EP) zowonjezera.Zowonjezera zapadera zitha kufunikira kuti muwonjezere magwiridwe antchito.Mafuta omatira komanso olimba monga Molybdenum Disulfide (Moly) amawonjezedwa kumafuta kuti apereke chitetezo chowonjezera pamene zinthu zafika povuta kapena kuyambiranso kumakhala kovuta.

Maphunziro a National Lubricating Grease Institute (NLGI) ndi muyeso wamafutakusasinthasintha.Ndiko kunena kuti imayesa kulimba kwamafuta kapena kufewa kudzera mu mayeso a ASTM D 217, "Cone Penetration of Lubricating Grease".Pali "makalasi" asanu ndi anayi a NLGI kuphatikiza 000, 00, 0, 1, 2, 3, 4, 5 ndi 6. Tonse timadziwa za "EP 2" mafuta.Izi zimatiuza zinthu ziwiri, mafuta a EP 2 ndi NLGI Giredi 2 ndipo amalimbikitsidwa ndi zowonjezera za Extreme Pressure (EP).Izi sizitiuza china chilichonse chokhudza mtundu wa thickener, mtundu wa mafuta oyambira kapena kukhuthala kwa mafuta oyambira.Kalasi yolondola ya NLGI ndiyofunikira chifukwa si mafuta onse omwe amafanana.Mafuta ena amafunikira girisi wofewa kotero kuti amatha kupopera mosavuta kudzera mumizere yaying'ono yogawa ndi mavavu.Pomwe mafuta ena opaka ngati ma bere oyikidwa pamiyendo yoyima amafunikira mafuta olimba kuti mafutawo azikhalabe.

Ndi mfundo zonsezi zofunika kuziganizira, n’zosadabwitsa kuti pali chisokonezo pa nkhani ya mafuta.Mafakitale ambiri amayenera kugwiritsa ntchito mafuta ochepa omwe amapaka mafuta pamalo awo onse.Payenera kukhala mafuta apadera:

• Magetsi Motors
• High Speed ​​Couplings
• Low Speed ​​Couplings
• Ma Applications Odzaza Kwambiri/Pang'onopang'ono
• General Grease Applications

Kuonjezera apo, mafuta apadera amodzi kapena awiri angafunike kuti agwiritse ntchito kwambiri.

Mafuta ndi zida zoperekera mafuta ziyenera kulembedwa mitundu ndi zilembo kuti zisawononge zinthu zomwe zingaipitse.Gwirani ntchito ndi ogulitsa kuti mudziwe ndikumvetsetsa mafuta omwe akugwiritsidwa ntchito pamalo anu.Posankha mafuta, yesetsani mosamala ndikusankha mafuta oyenera kuti mugwiritse ntchito.
