Paipu PTFEua hoʻohana mua ʻia ma ka ʻāpana kaʻa a ua lilo koke i mea kaulana. Hana maikaʻi nā hose i hana ʻia mai ka polytetrafluoroethylene ma mua o ka hose rubber i nā noi kaʻa ma muli o kona loaʻa ʻana ma ke kālepa kiʻekiʻe a me kāna hana maikaʻi loa, no laila ke piʻi nei kā lākou hoʻohana kalepa ma ke kaʻa.
He aha ka paipu PTFE?
ʻO ka hose PTFE he paipu i haku ʻia me kahi uhi PTFE o loko a me kahi papa ulana kila kila waho e like me ka uhi pale. Ua like ka uhi PTFE me kahi paipu PTFE me kahi uhi pale o waho, e hoʻonui ana i kona kūpaʻa kaomi, e like me ka hoʻohana ʻana o nā kaʻa no ka hose PTFE.
He aha nā ʻano o ka PTFE hose?
ʻAʻohe kemikala inert, kūpono no ka hapa nui o nā ʻano wahie
Ka permeability haʻahaʻa
Ka helu haʻahaʻa loa o ka friction
Māmā ke kaumaha
ʻAʻole pipili
ʻAʻole e pulu
ʻAʻole hiki ke lapalapa
Ke kūpaʻa ʻana i ka wā ʻino / ka ʻelemakule
Nā waiwai uila maikaʻi loa
ʻO ka hose wahie i hoʻopaʻa ʻia ʻo PTFE - nā ʻano:
Hose wahie PTFE wahine
ʻO ke kumu hose no ka wahine puʻupaʻaHose wahie PTFEHana ʻia ia me 100% PTFE resin me ka ʻole o kekahi pigment a mea hoʻohui paha.
Mea hoʻokele (Anti-static)Hose wahie PTFE
Hoʻoheheʻe static a i ʻole conductive piha no ka hoʻopau ʻana i nā hoʻopiʻi static e pili ana i ka hoʻoili wai hiki ke puhi. No ka holo ʻana me E85 a me Ethanol, a i ʻole Methanol Fuel, pono ka conductive PTFE i loko.
ʻO ka paipu PTFE no ka wahie - nā koho:
ʻO ka hose ulana PTFE me ka papa SS hoʻokahi - ʻO kekahi o nā hose wahie PTFE kaulana loa
ʻO ka paipu ulana PTFE me ka papa SS pālua - No ka hoʻonui ʻana i ke kaomi no kekahi mau noi
ʻO ka hose ulana PTFE me ka papa SS a me ka uhi Nylon ʻeleʻele - Pale maikaʻi i ka papa kila kila a me ke kū'ē ʻana i ka abrasion
ʻO ka paipu ulana PTFE me ka papa SS hoʻokahi a me ka uhi ʻia ʻana o PVC - Pale maikaʻi i ka papa kila kila a hoʻolilo iā ia i mea nani i kāu kaʻa
Ke hoʻohālikelike ʻia me ka hose wahie laholio, no ke aha e koho aiHose wahie PTFE?
He pani maikaʻi loa nā laina wahie PTFE no ka hose laholio. Me ka hana kūpono a me ka hale, hiki iā lākou ke paʻa loa a maʻalahi hoʻi e hoʻokomo i loko o ka ʻōnaehana. ʻOiai ʻaʻole lākou e hāʻawi i ka laulā elastic like i hana ʻia me ka laholio, kūpaʻa loa nā hose PTFE i ka hapa nui o nā kemika, a ʻaʻole lākou e hoʻokuʻu pinepine i nā uahi, he mea nui ia no kekahi ʻano wahi i pani ʻia. ʻO kēia kūpaʻa kemika hoʻi ke ʻano o ka palaho lohi o nā hose PTFE ma mua o nā hose laholio.
ʻOi aku ka haʻahaʻa o ka haʻalulu ʻili o ka PTFE ma mua o ka laholio, ʻo ia hoʻi hiki ke hoʻomaikaʻi ʻia ka nui o ke kahe ʻana ma ka hoʻohana ʻana i ka hose PTFE. ʻOiai ua maʻalahi ka palaho ʻana o ka laholio i nā mahana koʻikoʻi, kūpaʻa ka PTFE i nā mahana kiʻekiʻe, e lilo ia i koho kūpono no ka hose wahie i loko o ke kaʻa heihei.
ʻO ka mea mua, ʻo kaPaipu PTFEhana ma ke ʻano he pale mahu e pale ai i nā ʻala kinoea mai ke komo ʻana i loko o ka hale kaʻa a i ʻole ka hale kūʻai a me ke kuni ʻana i ka wā e hoʻomaha ai kāu holo.
ʻO ka lua, ʻo ka hose i hoʻopaʻa ʻia me ka PTFE ka mea i loaʻa ke kūpaʻa kemika kiʻekiʻe loa a kākoʻo i ka nui o nā wai kaʻa, kahi mea hiki ʻole me ka laholio maʻamau. ʻO ka mea maʻamau, aia ka ethanol i loko o ka ʻaila i hui pū ʻia. Hoʻopala nā hose laholio maʻamau i ka wā e launa pū ai me kēia ʻaila, a laila e palaho a hiki i kahi e hoʻomaka ai lākou e liki a hoʻokomo paha i ka wahie - he mea weliweli loa ia.
ʻO ke kolu, he kiʻekiʻe loa ke kūpaʻa ʻana o ka hose i hoʻopaʻa ʻia me ka PTFE i ka mahana - ʻo ka ʻoiaʻiʻo, ʻo ka pae mahana hana o ka hose i kūʻai ʻia e kā mākou hose wahie he -60 degere Celsius a i +200 degere Celsius. He kūpono loa ia e wehe i ka paipu wai ma kāu kaʻa haʻuki.
ʻO ka hā, he kiʻekiʻe loa ke kaomi hana o kā mākou hose PTFE wahie, e hōʻoiaʻiʻo ana e hiki iā ʻoe ke hoʻohana no nā ʻano noi kaʻa āpau. He kūpono ka nui AN6 no 2500PSI, kūpono ka nui AN8 no 2000psi-ʻoiai no nā noi koi loa, ua lawa ke kaomi.
He aha ka laina wahie āu e pono ai e holo me E85 a me ka ethanol, a i ʻole ka wahie methanol?
Ua lilo ka hoʻohana ʻana i ka ethanol a me nā wahie methanol i mea kaulana loa i nā makahiki i hala iho nei, ʻoiai me ka piʻi ʻana o nā ʻenekini turbocharged supercharged kiʻekiʻe-horsepower. Ua hōʻoia ʻia ʻo E85 a i ʻole ethanol he wahie kūpono i ke kumukūʻai e hiki ke hāʻawi i nā noi koi me ka helu octane a me ka mana. Eia kekahi, hiki iā ia ke hana i kahi hopena hoʻoluʻu ma ka ea komo.
Eia nō naʻe, he ʻino ka ethanol, i kekahi mau hihia e hana ia i kahi mea like me ka gel, a hiki ke hōʻino i nā ʻāpana ʻōnaehana wahie, inā ʻaʻole, ʻaʻole ia e hoʻopilikia ʻia e ka ʻaila a me ke kinoea heihei.
Pono e hoʻohana ʻia kahi kānana wahie kūikawā. ʻOiaʻiʻo, pono ʻoe e hōʻoia i kūpono kāu pamu wahie, akā pehea ke ʻano o ka laina wahie?
Hiki ke hoʻolako ʻia ka hose PTFE me ka ulana kila kila a me ka uhi ʻeleʻele. Hoʻohana kēia PTFE kaila conductive i kahi ulana waho a me kahi liner PTFE o loko, kahi mea kūpaʻa loa i nā mea kemika a me ka decomposition thermal. He mea nui ka hoʻohana ʻana i ka uea conductive a noʻonoʻo inā e koho i ke koho PTFE, no ka mea, ʻo ka uku electrostatic i hana ʻia e ke kahe wahie e arc/puhi maoli a hana i ka uku, kahi e hoʻoulu ai i ke ahi.
ʻOi aku ka paʻakikī o ka hoʻākoakoa ʻana o ka PTFE, akā ʻaʻole maʻalahi ka hoʻopilikia ʻia o kona ola e ka mahana a me ke kaomi. ʻO kēia ka mea e lilo ai ia i koho maikaʻi loa no nā wahie ʻino, a me nā laina hoʻokele mana, nā laina ʻaila turbine, a pēlā aku. No kēia mau kumu, he koho maikaʻi nō hoʻi ia no nā wahie E85 a me ethanol a me methanol.
