Kāohi a Hoʻomaʻamaʻa ʻana i ka ʻino ʻana o ka ʻaupepa Butterfly

He aha ka corrosion okiwi lele?

Hoʻomaopopo pinepine ʻia ka ʻino ʻana o nā kīwaha butterfly e like me ka pōʻino o nā mea metala o ka valve ma lalo o ka hana o ke kemika a i ʻole ka electrochemical environment. Ma muli o ke ʻano o ka "corrosion" i ka launa pū ʻana ma waena o ka metala a me ke kaiapuni a puni, pehea e hoʻokaʻawale ai i ka metala mai ke kaiapuni a puni a i ʻole ka hoʻohana ʻana i nā mea synthetic non-metallic ke kumu o ka pale ʻana i ka corrosion. ʻO ke kino o kalele lele(me ka uhi valve) noho i ka hapa nui o ke kaumaha o ka valve a pili pinepine me ka mea waena, no laila, koho pinepine ia ka valve butterfly mai ka mea kino.

ʻElua wale nō ʻano o ka corrosion kino valve okiwi lele,ʻo ia hoʻi kaʻinoʻino a me kaʻino electrochemical. Hoʻoholo ʻia ka nui o ka corrosion e ka wela, ke kaomi, nā waiwai kemika o ka waena, a me ke kūpaʻa corrosion o ka mea kino valve. Hiki ke hoʻokaʻawale ʻia ka nui o ka corrosion i ʻeono pae:

1. Hoʻopau i ka pale ʻana i ka corrosion: ʻoi aku ka liʻiliʻi o ka corrosion ma mua o 0.001 mm / makahiki;

2. ʻO ke kūpaʻa ʻino loa: ka nui o ka corrosion 0.001-0.01 mm / makahiki;

3. Ke kū'ēʻana i ke kino: 0.01-0.1 mm / makahiki;

4. Kiʻekiʻe corrosion kū'ē: corrosion rate 0.1-1.0 mm / makahiki;

5. Poor corrosion kū'ē: corrosion rate 1.0-10 mm / makahiki;

6. Ke kū'ē'ēʻole:ʻoi aku ka nui o ka corrosion ma mua o 10 mm / makahiki.

Pehea e pale ai i ka corrosion okiwi lele?

ʻO ka anti-corrosion o ke kino valve o ka valve butterfly ma muli o ke koho kūpono o nā mea. ʻOiai he waiwai loa ka ʻike e pili ana i ka anti-corrosion, ʻaʻole maʻalahi ke koho ʻana i ka mea kūpono, no ka mea, paʻakikī loa ka pilikia o ka corrosion, no ka laʻana, ʻoi loa ka sulfuric acid i ke kila i ka haʻahaʻa haʻahaʻa, a i ka wā e kiʻekiʻe ai ke kiʻekiʻe, hana ke kila i kahi kiʻi passivation, hiki ke pale i ka corrosion; Hōʻike wale ʻia ka hydrogen i ke kila i ke kiʻekiʻe o ka wela a me ke kaomi, a ʻaʻole nui ka hana corrosion o ke kinoea chlorine i ka wā maloʻo, akā ikaika loa ka hana corrosion inā loaʻa kahi haʻahaʻa, a ʻaʻole hiki ke hoʻohana ʻia nā mea he nui. ʻO ka paʻakikī o ke koho ʻana i nā mea kino valve ʻaʻole hiki iā mākou ke noʻonoʻo wale i nā pilikia corrosion, akā e noʻonoʻo pū kekahi i nā mea e like me ke kaomi a me ka pale ʻana i ka mahana, inā he kūpono ke kālā, a inā he maʻalahi ke kūʻai. No laila pono ʻoe e makaʻala.

1. ʻO ka lua, ʻo ia ka lawe ʻana i nā ana lining, e like me ke kēpau, ka aluminika, ka ʻenekinia plastics, ka lāʻau maoli a me nā ʻāpana synthetic like ʻole. Inā ʻae ke kūlana waena, he ala mālama kēia.

2. ʻO ke kolu, inā ʻaʻole kiʻekiʻe ke kaomi a me ka mahana, ʻo ka mea nui o ka valve butterfly i hoʻopaʻa ʻia i ka fluorine hiki ke hana maikaʻi loa i ka pale ʻana i ka corrosion.

3. Eia kekahi, ua ʻino ʻia ka ʻili o waho o ke kino valve e ka lewa, a ʻo ka mea hao ductile e pale mau ʻia e ka nickel plating.

E hoʻokuʻu koke ʻo TWS i kahi laina huahana anti-corrosion hou, e uhi ana i kahi ākea piha o nā ʻōnaehana valve e like mekiwi lele, kiwi puka, nā pahu hopua me na kiwi poepoe, etc. Hoʻohana kēia ʻano huahana i ka ʻenehana pale corrosion kiʻekiʻe a me nā kaʻina hana lapaʻau kūikawā e mālama i ka hana sila maikaʻi a me ka paʻa o ka hana ma lalo o nā kūlana hana koʻikoʻi. Hoʻopaʻa mākou i ka hāʻawi ʻana i nā mea kūʻai aku me nā huahana valve ʻoihana paʻa, hoʻonui nui i ke ola lawelawe o nā lako, e hōʻemi ana i nā kumukūʻai mālama i ke ola a pau.ka lōʻihipōʻai, a kōkua i nā mea kūʻai aku e hoʻokō i nā hoʻoholo kūʻai waiwai kiʻekiʻe.
