he aha ke sila aila a he aha ka ʻokoʻa ma waena o ka sila aila TC, sila aila TB, sila aila TA?

Hoʻopuka ka mīkini i ka sila aila

• ʻO TC ke ʻano hōʻike no nā kūlana aupuni hou.

Iāpana, Taiwan, a me nā wahi ʻē aʻe.ʻO FB ke ʻano hōʻike o ka maʻamau aupuni kahiko, me ke ʻano like a me ka ʻike.Pēlā nō, hoʻohana nui nā kūlana ʻEulopa i ka AS e hōʻike i nā sila aila TC a me FB.ʻO nā kūlana no ka FB a me ka FC he GB10708.3-189.ʻO TC ke ʻano hōʻike no nā kūlana aupuni hou, Iapana, Taiwan, a me nā wahi ʻē aʻe.ʻO ka ʻaila hinu TC kahi mea mīkini i hoʻohana ʻia e sila ai i ka ʻaila (ʻo ka ʻaila ka mea wai maʻamau i nā ʻōnaehana hoʻouna, i kapa ʻia hoʻi he mea wai maʻamau).

(1).ʻO FB ke ʻano hōʻike o ke kūlana aupuni kahiko, me ke ʻano like a me ka ʻike.

(2).Nui nā kūlana kūloko ma ʻEulopa e hoʻohana i ka sila ʻaila AS e hōʻike i nā sila aila TC a me FB.

Hoʻohana nui ʻia nā sila aila i nā ʻano ʻoihana like ʻole, ʻoi aku ka nui o nā mea mīkini e like me nā ʻōnaehana hydraulic, nā ʻenekini, nā paila, nā pahu pahu, nā mea hoʻouna, a me nā kaʻa.Kōkua lākou i ka mālama ʻana i ka hana maʻamau o nā mea hana mīkini, hoʻonui i ke ola lawelawe o nā mea hana, hoʻemi i nā kumukūʻai mālama, a hōʻoia i ka hana pono o nā mea hana.

Pono e noʻonoʻo ka hoʻolālā a me ke koho ʻana i nā sila ʻaila he nui, e like me ka ʻenehana hana, ke ʻano wai, ka pae wela, nā koi koi, nā koi wikiwiki, a me nā mea ʻē aʻe.ʻO nā ʻano maʻamau o nā sila aila he mau sila rotary shaft, sila piston, sila static, etc. He mau lehelehe o loko a me waho ka lehelehe o loko, me ka lehelehe o loko e pili ana i ke kumu wili a me ka lehelehe waho e pili ana i nā mea paʻa.Hoʻokumu kēia i kahi hopena sila ma muli o ke kuʻi ʻana ma waena o nā lehelehe o loko a me waho i ka wā o ka hana ʻana o ka ʻau.

I ka hōʻuluʻuluʻana, he koʻikoʻi koʻikoʻi nā sila aila i nā kula e like me ka mīkini ʻenekinia, nā kaʻa, a me nā mea hana ʻoihana, e hōʻoia ana i ka hana maʻamau o nā lako mīkini, pale i ka leakage wai a me nā haumia o waho mai ke komo ʻana, e hōʻoiaʻiʻo ai i ka paʻa, palekana, a me ka hana maikaʻi. ka lako.

1.ʻO ke ʻano hōʻikeʻike sila ʻaila

Nā ʻano hana hōʻike maʻamau:

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

No ka laʻana, TC40 * 62 * 12-NBR e hōʻike ana i kahi lehelehe ʻelua lehelehe aila ʻili i loko me ka anawaena o loko o 40, kahi anawaena o waho o 62, kahi mānoanoa o 12, a me kahi mea nitrile rubbe.

2.Material o ka sila aila

Nitrile rubber (NBR): pale ʻaʻahu, pale aila (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, kaʻaila kū'ē (ʻo kaʻaila a pau), ka mahana pale: -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, hoʻonohonoho hoʻoemi liʻiliʻi, ikaika mechanical haʻahaʻa, pale wela: -60 ~ 250 ℃ (kūpono wela maikaʻi loa).

Polytetrafluoroethylene (PTFE): Paʻa kemika maikaʻi, kū'ē i nā media like ʻole e like me ka waikawa a me ka alkali, ka aila, ke kūpaʻa ʻaʻahu, ke kūpaʻa wela kiʻekiʻe, ka ikaika mechanical kiʻekiʻe, a me ka lubrication ponoʻī.

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 lubrication ponoʻī maikaʻi, ʻoi aku hoʻi i ka wā i hoʻohui ʻia me ke keleawe, ʻoi aku ka maikaʻi o nā hopena, a hoʻohana ʻia lākou e hana i nā apo paʻa, nā apo Gly, a me nā sila Stuart.

Hoʻokaʻawale i ke kumu hoʻohālike o ka sila ʻaila iwi

Hiki ke hoʻokaʻawale ʻia ke sila ʻaila C-type i ʻelima mau ʻano: ʻano SC, ʻano TC, ʻano VC, ʻano KC, a me ke ʻano DC.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 moʻokāki "Mechanical Engineer" e ʻike i ka ʻike waiwai maloʻo a me ka ʻike ʻoihana i ka manawa mua)

ʻO ke sila ʻaila iwi ʻano G-type he ʻano hilo ma waho, e like me ka C-type.Hoʻololi waleʻia ka loaʻaʻana o kahi hiʻohiʻona ma waho e pili ana i kaʻenehana, e like me ka hana o ka O-ring,ʻaʻole e hoʻoikaika wale i ka hopena o ka sila akā e hoʻoponopono i ka silaʻaila me ka weheʻole.

ʻO ka sila ʻaila iwi B-type he pipili ma ka ʻaoʻao o loko o ka iwi a ʻaʻohe mea hoʻopili ma nā ʻaoʻao ʻelua o ka iwi.ʻO ka loaʻa ʻole o ka adhesive e hoʻomaikaʻi i ka hana hoʻopau wela.

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

3. Loaʻa iā lākou nā ʻano like ʻole o nā sila aila a ua kapa ʻia lākou he mau sila aila kumu nui e like me kēia:
