Umthelela wamafutha okugcoba ku-bearing
Isikrini esidlidlizayo ukuthwala amafutha okugcoba kunezinto ezifanayo namafutha okugcoba. Bobabili banokusebenza okuhle kokulwa nokugqokwa kanye nokumelana nokucindezela okukhulu.Izingxenye eziqukethwe ku-lubricant zingasiza ngempumelelo ekunciphiseni ukungqubuzana. Ukushisa okukhiqizwa ukungqubuzana kulawulwa kuya ebangeni eliphansi kakhulu, futhi anokumelana ne-oxidation okuhle kakhulu nokuzinza.
Ingaqinisekisa ngokuphumelelayo ukuthi izingxenye zokugcoba zingasebenza endaweni ephakeme yokushisa isikhathi eside, futhi futhi zigcine ukusebenza okuvamile, okunganweba kakhulu impilo yesevisi yokuthwala. Ngaphezu kwalokho, impilo yesevisi yemishini yokuthwala ngamafutha akhethekile ingaphezu kokuphindwe kabili kune-bearing ngaphandle kwamafutha akhethekile.
Kunezimo eziningi zokusebenzisa amabheringi esikrini adlidlizayo, kusukela ekungcoleni okuphezulu nokugqwala kuya kumazinga okushisa aphezulu kanye nomthelela wengcindezi ephezulu. Ezimweni ezihlukene, izinkomba zobuchwepheshe ezidingekayo kuma-bearings ngokwemvelo ziyahlukahluka kakhulu.
Ezimweni ezahlukene, isihenqo isixwayisi amafutha athwalayo ngokuvamile ahlukaniswe abe izinhlobo ezinhlanu: enye igrisi yenhloso evamile, enye iwumsebenzi osindayo kanye namafutha agcwele umthwalo, eyesithathu i-anti vibration kanye namafutha anomthelela, eyesine igrisi enezinga eliphezulu lokushisa, kanti eyesihlanu amafutha akhethekile ezimbonini ezikhethekile. Imininingwane imi kanje:
1, Inhloso evamile yamafutha asetshenziselwa izinto eziningi. Igrisi evamile enezinjongo eziningi iyasebenza kumthwalo ovamile kanye nezinga lokushisa. Kwaziwa nangokuthi amafutha ezimoto kanye nezimboni ezijwayelekile. Lawa mafutha anokusebenza kahle, ukumelana nokugqokwa okuhle nokumelana nokugqwala, futhi afanele ukusetshenziswa okuningi okufana nemishini yezolimo, imishini yokuwasha, izinto zokubamba izinto ezibonakalayo, imishini evamile, izinjini zamandla amancane, amasondo amasondo emoto, amathuluzi amancane, njll. ukusuka - 25 ° C kuya +140 ° C.
2, Umsebenzi osindayo ophezulu wamafutha. I-heavy duty kanye ne-high load grease ifanele izicelo ezinokucindezeleka okuphezulu. Lolu hlobo lwamafutha lusebenza kahle kakhulu ngaphansi komthwalo omkhulu, isivinini esikhulu kanye nesivinini esiphansi, ukusebenza kahle lapho kunamanzi, ukumelana okuhle nokugqokwa nokugqwala, futhi lufaneleka ukucindezela okukhulu kusuka -25 ° C kuya ku-+140 ° C, njengezinjini ezinamandla amakhulu, amaconveyor, okokuphakamisa izinto, izindawo zamaloli, amaphampu amanzi, imishini yokunyathelisa, njll.
Isibonelo, i-Great Wall BLC-G ephethe igrisi yenziwe ngensipho eyinhlanganisela ejitshiswe uwoyela wesisekelo wokwenziwa wekhwalithi ephezulu kanye nefomula yokwengeza ekhethiwe ngenqubo ekhethekile. Inokusebenza okuhle kakhulu kwezinga lokushisa eliphezulu nokuphansi, ukumelana nokugqwala, ukumelana nokucindezela okwedlulele, ukumelana ne-oxidation, kanye nokumelana nokugqokwa kwe-fretting okuyingqayizivele.
Ifanele ukuthwala izingxenye zokugcoba ezinezidingo eziphezulu ekushiseni okuphezulu nokuphansi, ukucindezela okukhulu nokugqoka. I-Great Wall BLC-G ephethe igrisi ingathuthukisa indawo yokuthambisa ye-bearing, yenze kube lula ukukhishwa kwamafutha angcolile, futhi inwebe impilo yesevisi ye-bearing. I-Great Wall BLC-G ephethe igrisi ithuthukiswe ukuxazulula ukugcotshwa okuhlangene kwamabheringi enjini yomoya, futhi ingasetshenziselwa ukugcotshwa kwawo wonke ama-bearings enjini yomoya.
3, Ukudlidliza kanye nomthelela wamafutha amelana. I-anti vibration kanye ne-anti- impact grease ilungele izinhlelo zokusebenza ezingaphansi kwamazinga aphezulu okudlidliza noma umthwalo womthelela. Igrisi eklanyelwe ngokukhethekile ukufakwa kwemithwalo ephezulu ezinkwalini, ezitshalweni zikasimende, kwezobunjiniyela bezolimo nezokulima, nasezindaweni ezimanzi, njengezigayo zephepha kanye nezimbambi. Lokhu kuthwala kunokumelana nomthelela omuhle kakhulu, izinga eliphezulu lokudlidliza nomthwalo osindayo, nokumelana namanzi okuhle kakhulu. Isebenza ku-spindle yebhakede, igrinder, i-crusher, isikrini esidlidlizayo, umshini wokuwasha, ifeni yasembonini, njll. at – 25 ° C kuya+140 ° C.
4, Gcoba izinga lokushisa eliphezulu. Njengoba igama lisho, amafutha okushisa aphezulu amelana kakhulu nokushisa okuphezulu futhi ahlinzeka ngokugcotshwa okuzinzile isikhathi eside emazingeni okushisa aphansi futhi aphezulu ukusuka - 40 ° C kuya ku-+180 ° C. La mafutha anokumelana okuhle kakhulu kokugqoka, ukumelana nokugqwala nomsindo ophansi. Ngakho-ke, akufanelekile kuphela ezindaweni eziphakeme zokushisa, njengama-dryer, ama-oven conveyors, imishini yendwangu kanye nemishini yokucubungula iphepha, kodwa futhi nama-motor, ama-generator, amaphampu, njll.
5, amafutha akhethekile ezimboni ezikhethekile. Ngaphezu kwamafutha okugcoba avamile, kukhona futhi amafutha okugcoba akhethekile kwezinye izindawo ezikhethekile, njengama-servo motors anesivinini esikhulu. I-ME-1 motor-long-life lubricating grease isetshenziswa, njengemishini yokukhiqiza i-semiconductor, igrisi eqinile eyizinhlayiyana ezincane, indawo ye-interstellar, i-vacuum grease, i-ultra-low (high) yokushisa amafutha okugcoba, igrisi yebanga lokudla, i-insulation grease, njll.
