Graphite mafuta ndi ntchito yake m'magalimoto

Mafuta a graphite - mafuta opangira ma inorganic komanso, amtundu wakuda kapena woderapo, wokhala ndi kukhazikika komanso kowoneka bwino kwambiri. Kunja, akufanana ndi mafuta odziwika bwino. Mafutawa amapangidwa pamaziko a mafuta a masamba omwe amagwiritsa ntchito mafuta amafuta a petroleum cylinder mafuta ndi sopo za lithiamu kapena calcium, komanso graphite. Graphite ufa amagwiritsidwa ntchito ngati chomaliza. Mogwirizana ndi GOST 3333-80, malinga ndi momwe amapangidwira, kutentha kwabwino kwambiri kumayambira -20 ° C mpaka +60 ° C, komabe, kwenikweni, imatha kupirira kutentha kwambiri. Mafuta a graphite amagwiritsidwa ntchito kwambiri m'makampani, komanso potengera makina. ndiko kuti, amapaka akasupe, zinthu zoyimitsidwa, mayendedwe odzaza kwambiri, magiya otseguka, ndi zina zotero.

Kupanga mafuta a graphite

Choyamba, muyenera kudziwa kuti mu mabuku luso mawu akuti "mafuta graphite" angatanthauze nyimbo zosiyanasiyana. Chowonadi ndi chakuti poyamba tanthauzoli limatanthawuza mafuta odzola, omwe graphite amagwiritsidwa ntchito ngati thickener, koma m'lingaliro lalikulu, mafuta amatchedwanso choncho, pamene graphite imagwiritsidwa ntchito ngati chowonjezera. Choncho, mawu akuti "graphite lubricant" angatanthauze:

graphite wosweka

• ufa wamba wa graphite, womwe ungagwiritsidwe ntchito ngati mafuta olimba;
• mafuta opangidwa ndi sopo okhala ndi graphite;
• Kuyimitsidwa kwa graphite mu njira yamafuta (mafuta amtundu wa inorganic).

Ndilo gawo lomaliza lomwe nthawi zambiri limatchedwa graphite grease, ndipo lidzakambidwanso. Ukadaulo wake wopanga umaphatikizapo kukulitsa mafuta a viscous organic kapena opangidwa, omwe amachokera kumafuta amafuta, ndi sopo wa calcium ndi ufa wa graphite. Mwanjira ina, titha kunena kuti ufa wa graphite umawonjezeredwa kumafuta apamwamba, omwe amapereka mafutawo.

Graphite ufa wokha uli ndi mawonekedwe ofewa. Choncho, monga gawo la mafuta odzola, amadzaza zolakwika pa malo ogwirira ntchito a zigawozo, motero amachepetsa kukangana.

Pakali pano, mafuta a copper-graphite amapezekanso pogulitsidwa. Ufa wa mkuwa umawonjezeredwa ku kapangidwe kake. Imatha kupirira kutentha kwambiri. Nthawi zambiri mafuta a copper-graphite amapezeka mu mawonekedwe a aerosols. Kuyang'ana m'tsogolo, tinene kuti kalembedwe kameneka kamagwiritsidwa ntchito pazitsogozo za caliper. Mwanjira iyi mutha kupewa kumamatira ma diski ndi / kapena ng'oma zophwanyira ku ma flanges.

Makhalidwe a graphite mafuta

Payokha, graphite imapangitsa kutentha ndi magetsi bwino, sichimagwa chifukwa cha chinyezi, sichimakhudzidwa ndi magetsi osasunthika, komanso imakhala yolimba kwambiri (imatha kupirira kutentha kwakukulu). Zinthu zonsezi, ngakhale pang'ono, zimakhala ndi mafuta ofananira.

Kodi mafuta abwino a graphite ndi chiyani? Ubwino wake ndi:

• kukana mankhwala (pogwiritsa ntchito mafuta pamalo ogwirira ntchito, zinthu zake sizilowa nawo muzochita nawo);
• kukana kwamafuta (sikusuntha mpaka kutentha kwa +150 ° C, popeza kuchuluka kwa zinthu zosasunthika m'mapangidwe ake kumakhala kochepa, sikutaya mawonekedwe ake pa kutentha kwakukulu);
• imateteza malo ogwirira ntchito ku chinyezi;
• wawonjezera kukhazikika kwa colloidal;
• zosaphulika;
• ali ndi mafuta abwino kwambiri;
• kumawonjezera kukana kuvala, kugwira ntchito kwamakina ndi moyo wautumiki wa makina omwe amagwiritsidwa ntchito;
• kuchepetsa kuchuluka kwa khunyu;
• osakhudzidwa ndi mafuta, ndiko kuti, amakhalabe pamwamba ngakhale atakhalapo;
• mafuta a graphite amamatira bwino pamtunda uliwonse;
• kugonjetsedwa ndi magetsi osasunthika;
• ali mkulu zomatira ndi antifriction katundu.

komanso mwayi umodzi wofunikira wamafuta a graphite ndi ake mtengo wotsika ndi magwiridwe antchito okhutiritsa. Ngakhale, mwachilungamo, ziyenera kuzindikiridwa kuti pakali pano pali mafuta ena ambiri, omwe ali okwera mtengo, omwe, ngakhale kuti ndi okwera mtengo, ali ndi ntchito yabwino.

Komabe, mafuta a graphite alinso ndi zovuta zake. ndiye kuti, sichingagwiritsidwe ntchito pamakina olondola kwambiri, popeza zonyansa zolimba zomwe zimapezeka mu graphite zidzathandizira kuwonjezereka kwa magawo;
