Hoʻolauna i ka ʻike ʻaila ʻaila piha loa.

ʻO ka ʻaila sila he mea mīkini i hoʻohana ʻia no ka sila ʻana, ʻike ʻia hoʻi he apo lehelehe lehelehe rotating shaft.Mālama ʻia ka ʻāpana friction o ka mīkini mai ke komo ʻana o ka aila i ka wā o ka hana, a hoʻohana ʻia nā sila aila e pale ai i ka leakage aila mai ka mīkini.ʻO nā mea maʻamau ʻo nā sila ʻaila iwi.

1 、 Aila hōʻike ʻano hana

Nā ʻano hana hōʻike maʻamau:

ʻAno sila ʻaila - anawaena o loko - anawaena o waho - kiʻekiʻe - mea

No ka laʻana, TC30 * 50 * 10-NBR e hōʻike ana i kahi lehelehe ʻelua lehelehe ʻaila aila i loko me ka anawaena o loko o 30, kahi anawaena o waho o 50, a me ka mānoanoa o 10, i hana ʻia me ka nitrile rubber.

2、Material o ke sila aila iwi

Nitrile rubber (NBR): pale ʻaʻahu, pale ʻaila (ʻaʻole hiki ke hoʻohana ʻia i ka media polar), pale wela: -40~120 ℃.

Hydrogenated nitrile rubber (HNBR): ʻO ka pale ʻana i ka ʻaʻahu, ke kūpaʻa ʻaila, ka pale ʻana i ka wā kahiko, ke kū ʻana o ka mahana: -40~200 ℃ (ʻoi aku ka ikaika ma mua o ka pale wela NBR).

ʻO ka Fluorine adhesive (FKM): kaʻakika a me ka alkali kū'ē,ʻaila kū'ē (kū'ē i nāʻaila a pau), pale wela: -20 ~ 300 ℃ (ʻoi aku ka maikaʻi o kaʻaila ma mua o nā meaʻelua i luna).

ʻO ka polyurethane rubber (TPU): ʻAʻahu i ke kū'ē, ke kū'ē i ka wā kahiko, ke kū'ē wela: -20 ~ 250 ℃ (kū'ē kū'ē maikaʻi loa).

Silicone rubber (PMQ): pale wela, pale anu, me ka hoʻoemi liʻiliʻi i ka hoʻololi mau a me ka ikaika mechanical haʻahaʻa.Kū'ē wela: -60~250 ℃ (kū'ai wela maika'i).

Polytetrafluoroethylene (PTFE): he kūpaʻa kemika maikaʻi, kūʻē i nā ʻano media like ʻole e like me ka waikawa, ka alkali, a me ka aila, ke kūpaʻa a me ke kūpaʻa wela kiʻekiʻe, ka ikaika mechanical kiʻekiʻe, a me nā waiwai lubricating maikaʻi.

ʻO ka ʻōlelo maʻamau, ʻo nā mea i hoʻohana mau ʻia no nā sila aila iwi he nitrile rubber, fluororubber, silicone rubber, a me polytetrafluoroethylene.Ma muli o kāna mau waiwai lubricating maikaʻi, ʻoi aku ka nui o ka hoʻohui ʻana i ke keleawe, ʻoi aku ka maikaʻi o ka hopena.Hoʻohana ʻia lākou a pau no ka hana ʻana i nā apo paʻa, nā apo Glee, a me nā lāʻau.

3、 Hoʻokaʻawale i ke kumu hoʻohālike o ka iwi iwisila aila

Hiki ke hoʻokaʻawale ʻia ke sila ʻaila C-type i ʻelima mau ʻano: SC oil seal type, T Coi seal type, VC oil seal type, KC oil seal type, a me DC oil seal type.ʻO lākou ka lehelehe hoʻokahi lehelehe ʻili aila ʻili, lehelehe ʻelua lehelehe ʻaila aila lehelehe, lehelehe puna hoʻokahi manuahi i loko o ka ʻili aila ʻili, ka lehelehe lua lehelehe ʻaila aila ʻeleʻele i loko, a me ka lehelehe lua puna manuahi i loko o ka ʻaila aila.(Manaʻo mākou iā ʻoe e hoʻolohe i ka moʻolelo kūhelu "Mechanical Engineer" e ʻike i ka ʻike waiwai maloʻo a me ka ʻike ʻoihana i ka manawa mua)

ʻO ke ʻano o ka ʻaila skeleton G-type he ʻano hilo ma waho, ʻo ia ke ʻano like me ka C-type.Eia naʻe, ua hoʻololi ʻia e loaʻa kahi ʻano hilo ma waho i ke kaʻina hana, e like me ka hana o kahiO- apo, ʻaʻole ia e hoʻonui wale i ka hopena sealing akā kōkua pū kekahi i ka hoʻoponopono ʻana i ka sila ʻaila mai ka wehe ʻana.

ʻO ka sila ʻaila iwi B-type he mea hoʻopili ma ka ʻaoʻao o loko o ka iwi a ʻaʻohe mea hoʻopili i loko a i waho paha o ka iwi.ʻO ka nele o nā mea adhesive e hoʻomaikaʻi i ka hana hoʻopau wela.

ʻO A-type skeleton oil seal he sila aila i hui pū ʻia me kahi ʻano paʻakikī i hoʻohālikelike ʻia i nā ʻano ʻekolu i luna aʻe, i hōʻike ʻia e ka hana ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi.
