ʻO Nigrol. Makuakane o na aila kaila hou

Nā hiʻohiʻona maʻamau a me ka hoʻohana

Ua hoʻohana nui ʻia ka nigrol kuʻuna i ka wā ma mua ma ke ʻano he ʻaila ʻaila no ka lubrication o nā mīkini mīkini o nā mea koʻikoʻi i hoʻopaʻa ʻia a huila, a me nā ʻāpana hoʻoneʻe o nā lako mahu, e ʻike mau ʻia i ka mahu a me nā wela kiʻekiʻe. Wahi a GOST 542-50 (hoʻopau hope ʻia i ka makahiki 1975), ua hoʻokaʻawale ʻia ka nigrol i "kauwela" a me "hoʻoilo" - ʻokoʻa nā hōʻailona i nā ʻāpana viscosity, no ka "kauwela" nigrol ʻoi aku ka kiʻekiʻe, hiki i 35 mm.²/Me. Ua ninini ʻia kēlā lubricant i loko o nā axles o nā kaʻa a hoʻohana nui ʻia i nā kaʻa: ʻoi aku ka haʻahaʻa o nā ukana pili no nā kaʻa o ia manawa.

Aia ka waiwai nui o ka nigrol i ka pakeneka kiʻekiʻe o nā mea resinous i loko o ia mea i loaʻa i kekahi mau māka o ka aila. ʻO kēia ke kumu o ka lubricity kiʻekiʻe o kēia mea.

Nā nigrol hou: nā ʻokoʻa

ʻO ka hoʻopiʻi ʻana o nā kūlana hana o nā ʻano mea halihali hou i alakaʻi i ka emi ʻana o ka pono o ka nigrol maʻamau, no ka mea ʻaʻole i loaʻa nā mea hoʻohui antiwear, a me ka hoʻonui ʻana i ka viscosity i alakaʻi i ka hoʻonui ʻana i nā ukana ma nā mea hoʻouna. ʻOi aku ka maikaʻi o nā hāmeʻa hypoid kahi kiʻekiʻe nā poho friction. No laila, ʻo ka manaʻo o "nigrol" wale nō ke kapa inoa ʻia, a ʻo kēia hōʻailona ʻo ia hoʻi ka mea maʻamau i nā aila hoʻouna e like me Tad-17 a i ʻole Tep-15.

Nāʻano

ʻO Nigrol Tad-17 kahi hōʻailona o ka aila kaʻa kaʻa, ʻo ia nā hiʻohiʻona:

1. Hoʻonui i ka pale ʻana i ka friction sliding i ka hihia o nā ʻokoʻa koʻikoʻi i ka wikiwiki o nā mea pili o nā hoʻoili mechanical.
2. ʻO ka loaʻa ʻana o nā mea hoʻohui e hōʻoia i ka noho mau a me ka hana hou ʻana o ka kiʻi ʻaila ʻili.
3. ʻOi aku ka liʻiliʻi (i ka hoʻohālikelike ʻana me nā nigrols maʻamau) ka waiwai o ka viscosity pili.
4. Hoʻemi ʻia ka hilinaʻi ʻana o ka viscosity i ka mahana i hana ʻia ma ka wahi pili.

Aia nā mea hoʻohui i ka sulfur, phosphorus (akā ʻaʻole ke alakaʻi!), Nā ʻāpana anti-foam. ʻO ka helu ma hope o ka pōkole leka e hōʻike ana i ka viscosity o ka lubricant, mm²/s, aia ka huahana ma 100^ºH.

Hōʻike ʻia ka hana lubricant ma lalo nei:

• viscosity maʻamau, mm²/s, ʻaʻole ʻoi aku ma mua o - 18;
• pae wela hana, ^ºC - mai -20 a +135;
• ka mana hana, tausani km - a hiki i 75 ... 80;
• pae ikaika o ka hana - 5.

Ma lalo o ka pae hoʻopaʻapaʻa, manaʻo ʻo GOST 17479.2-85 i kahi mana kiʻekiʻe kiʻekiʻe, multifunctionality o ka hoʻohana ʻana, ka hiki ke hana ma lalo o nā ukana pili a hiki i 3 GPa a me nā mahana kūloko i nā ʻāpana hoʻonohonoho a hiki i 140 ... 150^ºH.

Hoʻoponopono ʻia nā ʻāpana ʻē aʻe o Tad-17 e GOST 23652-79.

ʻO ka lubricant brand Nigrol Tep-15 he haʻahaʻa haʻahaʻa haʻahaʻa, no laila ʻoi aku ka kiʻekiʻe o ka maikaʻi o ka hoʻouna ʻana i kahi e hoʻohana ʻia ai kēia ʻaila. Eia kekahi, ʻo nā pono o kēia lubricant:

1. Kiʻekiʻe anti-corrosion hana.
2. Paʻa viscosity ma luna o kahi ākea wela.
3. Hoʻonui i ka maikaʻi o ka distillate mua, kahi e hōʻoia ai i ka liʻiliʻi o nā haumia mechanical i loko o ka lubricant (ʻaʻole ʻoi aku ma mua o 0,03%).
4. ʻO ka neutrality o ka pH index, ka mea e pale ai i ka hoʻokumu ʻana o ka foci o ka hoʻonohonoho ʻana i ka wā o ka hoʻouna ʻana.

I ka manawa like, mālama pono ʻia nā hōʻailona kūʻokoʻa o ka mana anti-wear o kēia ʻaila kaila i nā haʻahaʻa haʻahaʻa wale nō. No laila, pono e haʻahaʻa ka wikiwiki o ka neʻe ʻana o nā ʻāpana lubricated. ʻIke ʻia kēia no nā kaʻa i hoʻohana maʻamau (tractors, cranes, etc.).

Nā hōʻailona hana lubrication:

• viscosity maʻamau, mm²/s, ʻaʻole ʻoi aku ma mua o - 15;
• pae wela hana, ^ºC - mai -23 a +130;
• ka mana hana, tausani km - a hiki i 20 ... 30;
• pae ikaika o ka hana - 3 (nā ukana pili a hiki i 2,5 GPa, nā mahana kūloko i nā nodes hoʻonohonoho a hiki i 120 ... 140^ºC).

Hoʻoponopono ʻia nā ʻāpana ʻē aʻe o Nigrol Tep-15 e GOST 23652-79.

Nigrol. Kumukuai no ka lita

Hoʻoholo ʻia ke kumukūʻai o ka aila hoʻoili o ke ʻano Nigrol e nā kumu he nui, ʻo ia hoʻi:

1. ʻO ke ʻano o kahi pahu pahu kaʻa.
2. Kaulana wela o ka noi.
3. Ka manawa a me ka nui o nā kūʻai.
4. ʻO ke alo a me ka hoʻohui ʻana o nā mea hoʻohui.
5. hana a me ka manawa pani.

ʻO ke ʻano o nā kumukūʻai no ka nigrol he ʻano, ma muli o ka hoʻopili ʻana o ka ʻaila:

• i nā pahu o 190...195 kg - 40 rubles / l;
• i loko o nā pahu o 20 l - 65 rubles / l;
• i loko o nā pahu o 1 lita - 90 rubles / lita.

No laila, ʻo ka nui o ke kūʻai ʻana (a me ke kumukūʻai o nā waiwai) e hoʻoholo ʻia e ka ikaika o ka hana o kāu kaʻa, no ka mea, ʻaʻole hiki ke hoʻololi i ka lubricant i ka wā o waho.

Nigrol, he aha ia a ma hea e kūʻai ai?
