ʻEke ea laholio a apo ʻumbrella laholio paha ma lalo o ka ʻaha

Nā ʻeke ea laholio: ma ke ʻano maʻamau e lawelawe ma ke ʻano he cushioning a me ka uku. Ke hana nei ka pamu wahie, hiki iā ia ke hoʻoulu i kekahi mau haʻalulu a me nā loli kaomi. Hiki i ka ʻeke ea laholio ke omo i kēia mau haʻalulu a me nā loli kaomi ma o kona deformation elastic ponoʻī, e hōʻemi ana i ka hopena ma ka hui pamu wahie a me nā ʻāpana a puni, a me ka pale ʻana i ka pono o ke kūkulu ʻana o ka pamu wahie. Eia kekahi, hiki i ka ʻeke ea ke pāʻani i kahi hana uku ke loli ka pae wahie, e mālama ana i ke kaomi paʻa i loko o ka pamu wahie a me ka hōʻoia ʻana i ka hoʻomau ʻana o ka lako wahie.

ʻO ka gasket radiator: i hoʻokomo ʻia ma ka pilina ma waena o ka radiator a me ka poloka ʻenekini a i ʻole nā ​​​​​​ʻāpana ʻē aʻe e pale i ka liki ʻana o ka coolant. ʻO ke kūpaʻa wai a me ke kūpaʻa kemika o ka fluororubber e hiki ai iā ia ke hoʻololi i ka haku mele ʻana o ka coolant a mālama i ka hana sila maikaʻi i nā wahi wela kiʻekiʻe i ka wā o ka hana ʻenekini, e hōʻoiaʻiʻo ana i ka hana maʻamau o ka ʻōnaehana hoʻoluʻu.

3. Sila waha o ka ʻaha kūkā

Nā mea i manaʻo ʻia: FKM a i ʻole NBR (ʻūpā nitrile)

OFKM: Kūpono no nā wahie wela kiʻekiʻe, ʻino loa (e like me ka ethanol gasoline).

ONBR: Kumukūʻai haʻahaʻa, kūpono no nā hiʻohiʻona me ka wahie maʻamau (ʻaʻohe ethanol) a me ka mahana ≤ 100 ℃.

Hoʻolohe: ʻOi aku ka haʻahaʻa o ke kūpaʻa ʻana o ka NBR i ka ʻaila ma mua o FKM a pono e hoʻololi pinepine ʻia.

4. ʻEke ea/apo umbrella lalo

Nā mea i manaʻo ʻia: FKM a i ʻole HNBR (hydrogenated nitrile rubber)

FKM: Ke kūpaʻa kiʻekiʻe i ka mahana a me ka wahie, akā haʻahaʻa iki ka elasticity.

HNBR: ʻOi aku ka maikaʻi o ka elasticity, ke kūpaʻa ʻana i ka aila, a me ke kūpaʻa ʻana i ka ʻelemakule e like me FKM, e kūpono ana no nā ʻano airbag e pono ai ka uku hoʻoikaika.

ʻO kahi hopena ʻē aʻe: ʻO ka EPDM (ethylene propylene diene monomer rubber) kūpono wale nō ia no nā hiʻohiʻona pili ʻole i ka wahie.

3. ʻŌnaehana pahu wahie

1. Gasket sila pahu wahie

Nā mea i manaʻo ʻia: FKM a i ʻole NBR

FKM: kūpaʻa i ke komo ʻana o ka aila a me ka ʻelemakule, kūpono no ka hoʻopaʻa ʻana i ka wā lōʻihi.

NBR: Kumukūʻai haʻahaʻa, kūpono no nā wahie maʻamau (e like me ka ʻaila kuʻuna).

2. Diaphragm i loko o ka pahu wahie

Nā mea i manaʻo ʻia: FKM a i ʻole ka ʻūpā fluorosilicone

FKM: kūpaʻa i ka wahie a me ke kaomi kiʻekiʻe.

ʻO ka laholio Fluorosilicone: ʻoi aku ka maikaʻi o ka maʻalahi, kūpono no nā ʻano loli (e like me nā puʻupuʻu pahu wahie mokokaikala), akā ʻoi aku ke kumukūʻai.
