graphite lubricant. Zvimiro zvakasiyana
Zviri mukati
Maumbirwo uye hunhu
Kusvika iye zvino, kuumbwa kwe graphite grease hakusi pasi pemitemo yakasimba. Kunyange GOST 3333-80, iyo yakatsiva yekare GOST 3333-55, haigadziri kana huwandu kana hutano hwezvinhu zvinoshandiswa mukugadzira girasi regirafu. Iyo chiyero inongoratidza maitiro akajairwa egraphite girisi rudzi "USsA" uye hushoma hunodiwa zvivakwa.
Izvi zvinoshandiswa nevagadziri, vachiedza kuumbwa uye, semugumisiro, zvinhu zvekupedzisira zvechigadzirwa. Nhasi, zvikamu zviviri zvikuru zve graphite girisi zvinhu zviviri: gobvu yemaminerari base (kazhinji petroleum yakabva) uye yakatsetseka pasi graphite. Calcium kana lithium sipo, kudzvinyirira kwakanyanya, antifriction, kupararira kwemvura uye zvimwe zvinowedzera zvinoshandiswa sezvimwe zvinowedzera.
Dzimwe nguva hupfu hwemhangura hunowedzerwa kune graphite. Ipapo mafuta anonzi copper-graphite. Chiyero chemhangura-graphite girisi chiri kuchinjika chakanangana nekudzivirira kwenguva refu kwekubata kumeso kubva mukuora nekushomeka kwehama. Semuenzaniso, lubricant yakadaro inoshandiswa zvakanyanya mukubatanidza tambo uye akasiyana madhairekitori.
Maitiro e graphite grease, zvichienderana nekuumbwa, anosiyana zvakanyanya. Semuenzaniso, tembiricha shoma iyo iyo lubricant isingarasikirwe zvakanyanya nekurasikirwa kwayo inosiyana kubva -20 kusvika -50 ° C. Maximum: kubva ku +60 (yeiyo yakapfava UssA lubricant) kusvika +450 (yemazuva ano high-tech "graphites").
Chimwe chezvinhu zvinonyanya kutaurwa zve graphite girisi ndeye yakaderera coefficient ye friction. Izvi zvinowanikwa nekuda kwegraphite, mahwendefa uye makristasi ayo pachikamu chemolecular anonyungudika zvese zvine hukama kune mumwe nemumwe uye pane mamwe mapeji, zvisinei nemhando yenzvimbo idzi. Nekudaro, nekuda kwekuoma kwemakristasi ega ega, girisi iyi haikurudzirwe kuti ishandiswe mumayuniti ekukwesha ane hunyanzvi hwekugadzira uye madiki madiki pakati pezvikamu zvinosangana. Semuenzaniso, zvakaratidzwa kuti kuisa "graphite" panzvimbo yemamwe magirosi akakodzera (solidol, lithol, nezvimwewo) mukukunguruka mabheji kwakaderedza hupenyu hwavo hwebasa.
Graphite zvakare inosarudza iyo conductive zvimiro zvelubricant. Nokudaro, girasi re graphite rinoshandiswa kuchengetedza magetsi emagetsi kubva pakuora uye kuwedzera kupenya.
Inoshandiswa nei?
Chiyero che graphite lubricant kazhinji chakapamhama. Graphite yakazviratidza zvakanaka mumaviri akavhurika, umo kumhanya kwehama kufamba kwezvikamu kudiki. Haina kushambidzika nemvura kwenguva yakareba, haina kuoma uye haina kushatisa pasi pesimba rezvimwe zvakashata zvekunze zvinhu.
Mumotokari dzenguva dzose nemarori, graphite girisi inoshandiswawo zvakanyanya:
- threaded connections - kurwisana nekuora uye kunamatira kwetambo;
- bhora mabheji emavhiri anotungamirwa - semafuta makuru anopombwa mumuviri wemabhengi uye nekuwedzera kuiswa pasi peanthers;
- majoini echidhiraivho uye matipi - anoshandiswa nenzira yakafanana nemabhora ebhora;
- spline zvinongedzo - zvekunze uye zvemukati splines zvinozorwa kuti zvideredze kupfeka panguva yekufamba kwavo;
- zvitubu - zvitubu pachazvo uye anti-creak substrates zvinozorwa;
- contacts - sekutonga, idzi ibheteri terminals, tambo isina kunaka kubva kubhatiri kusvika kumuviri uye tambo yakanaka kubva kubhatiri kusvika kune yekutanga;
- se anti-creak layer pakubata mapurasitiki nesimbi.
Kunyangwe chokwadi chekuti nhasi musika unopa huwandu hwakawanda hwemhando yepamusoro uye yakagadziridzwa lubricant, graphite ichiri kudiwa pakati pevatyairi. Iyo yakanaka chiyero pakati pemutengo uye maitiro. Avhareji mutengo we100 magiramu e graphite lubricant inoshanduka yakatenderedza 20-30 rubles, iyo yakachipa zvakanyanya kupfuura yemazuva ano lubricant nziyo dzine hunhu hwakagadziridzwa. Uye apo chiyero chepamusoro chekudzivirira chisingadiwi, kushandiswa kwegraphite kuchava mhinduro yakanakisisa.
