Nigrol. Baba vemafuta egiya emazuvano

General maitiro uye kushandiswa

Traditional nigrol yakashandiswa zvakanyanya munguva yakapfuura semafuta egiya ekuzora magiya emagetsi anoteedzerwa uye ane mavhiri emidziyo inorema, pamwe nekufambisa zvikamu zvemidziyo yeutsi inogara ichioneswa chiutsi uye tembiricha yakakwira. Zvinoenderana neGOST 542-50 (yakazopedzwa muna 1975), nigrol yakakamurwa kuita "zhizha" uye "chando" - mamakisi akasiyana muviscosity paramita, ye "zhizha" nigrol yaive yakakwirira, ichisvika 35 mm.²/pamwe. Mafuta akadaro akadururwa mumaaxle emarori uye aishandiswa zvakanyanya mumagiya: mitoro yekusangana yemotokari dzenguva iyoyo yaive yakaderera.

Iko kukosha kukuru kwekushanda kwe nigrol kuri muhuwandu hwehuwandu hwezvinhu zvinobudisa resinous zvirimo zviripo mune mamwe mamakisi emafuta. Izvi zvinokonzeresa kuwanda kwakanyanya kwechinhu ichi.

Modern nigrol: kusiyana

Dambudziko rekushanda kwemaitiro emazuva ano emidziyo yekufambisa kwakakonzera kuderera kwekushanda kweyakajairika nigrol, sezvo yakanga isina antiwear additives, uye kuwedzera viscosity kwakakonzera kuwedzera mitoro pazvinhu zvekutapurirana. Kunyanya hypoid giya uko kurasikirwa kwekukwesha kwakakwira. Saka, ikozvino pfungwa ye "nigrol" inongoratidzwa chete, uye iyi mhando inowanzoreva kutapurirana mafuta akadai seTad-17 kana Tep-15.

Mamiriro

Nigrol Tad-17 imhando yemotokari giya mafuta, ayo maficha ari:

1. Kuwedzera kupikisa kutsvedza kukwesha muchiitiko chekusiyana kwakakura mukumhanya kwezvinhu zvinosangana zvema mechanical transmissions.
2. Kuvapo kwezvinowedzera zvinosimbisa kuvapo nguva dzose uye kuvandudzwa kwefirimu remafuta epamusoro.
3. Diki (mukuenzanisa neyakajairika nigrols) kukosha kwehama viscosity.
4. Kudzikira kutsamira kwe viscosity pane tembiricha inoitika munharaunda yekusangana.

Izvo zvinowedzera zvine sulfur, phosphorus (asi kwete mutungamiri!), Anti-foam components. Nhamba mushure mechidimbu chetsamba inoratidza viscosity yemafuta, mm²/s, icho chigadzirwa chine pa100^ºC.

Lubricant performance inoratidzwa pazasi:

• avhareji viscosity, mm²/s, kwete kupfuura - 18;
• kushanda tembiricha range, ^ºC - kubva -20 kusvika +135;
• kushanda simba, chiuru km - kusvika 75 ... 80;
• chiyero chekushanda - 5.

Pasi peyero yekumanikidzana, GOST 17479.2-85 inotora yakakwira yakanyanya kudzvanywa kugona, multifunctionality yekushandiswa, kugona kushanda pakubata mitoro inosvika 3 GPa uye tembiricha yemuno muzvikamu zvekuisa kusvika 140 ... 150^ºC.

Zvimwe zviyero zveTad-17 zvinotungamirirwa neGOST 23652-79.

Lubricant brand Nigrol Tep-15 ine yakaderera viscosity, saka kunyatsoshanda kwekutumira uko mafuta egiya aya anoshandiswa kwakatokwira. Uye zvakare, zvakanakira zvelubricant iyi ndezvi:

1. High anti-corrosion performance.
2. Viscosity kugadzikana pamusoro pehupamhi hwekushisa.
3. Kuvandudzwa kwehutano hwekutanga distillate, iyo inovimbisa hushoma hwehutsvina hwemagetsi huripo mune lubricant (kwete kupfuura 0,03%).
4. Kusarerekera kweiyo pH index, iyo inodzivirira kuumbwa kwefoci yekugadzika panguva yekufambisa basa.

Panguva imwecheteyo, zviratidzi zvakakwana zveanopesana-kupfeka kugona kweiyi mafuta egiya anochengetedzwa zvakakwana chete pamatembiricha akaderera. Nokudaro, kukurumidza kwekufamba kwezvikamu zvakasvibiswa zvinofanira kunge zvakaderera. Izvi zvinocherechedzwa zvakanyanya kune mota dzakatevedzwa dzekushandiswa kwese (matirakita, cranes, nezvimwewo).

Lubrication performance zviratidzo:

• avhareji viscosity, mm²/s, kwete kupfuura - 15;
• kushanda tembiricha range, ^ºC - kubva -23 kusvika +130;
• kushanda simba, zviuru zvemakiromita - kusvika ku20 ... 30;
• chiyero chekushanda - 3 (kusangana mitoro inosvika 2,5 GPa, tembiricha yemuno munzvimbo dzekumisikidza kusvika ku120 ... 140^ºNE).

Zvimwe zviyero zveNigrol Tep-15 zvinotungamirirwa neGOST 23652-79.

Nigrol. Mutengo parita

Mutengo wemafuta ekutepfenyura erudzi rweNigrol unotarwa nezvakati wandei zvinhu, zvinosanganisira:

1. Chimiro chegiya bhokisi remotokari.
2. Tembiricha yemhando yekushandisa.
3. Nguva uye huwandu hwekutenga.
4. Kuvapo uye kuumbwa kwezvinowedzera.
5. kuita uye kutsiva nguva.

Huwandu hwemitengo ye nigrol hune hunhu, zvichienderana nekurongedza kweoiri:

• mumadhiramu e190… 195 kg - 40 rubles / l;
• mumagaba e20 l - 65 rubles / l;
• mumagaba e1 litre - 90 rubles / litre.

Saka, huwandu hwekutenga (uye mutengo wezvinhu) hunotarwa nekusimba kwekushanda kwemotokari yako, sezvo kushandura lubricant mu-off-mwaka kuchiri kusingadzivisiki.

Nigrol, chii uye kupi kwekutenga?
