Kāohi a me ka mālama ʻana i ka palaho o ka valve pepeke

He aha ka pala onā kiwikā pepeke?

ʻO ka palaho o nā kiwikā pepeke ka mea maʻamau e hoʻomaopopo ʻia ʻo ia ka hōʻino ʻana o ka mea metala o ka kiwikā ma lalo o ka hana a ke kaiapuni kemika a electrochemical paha. ʻOiai ke ʻano o ka "palaho" e kū mai ana 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 hoʻohana paha i nā mea synthetic ʻaʻole metala ke kikowaena o ka pale ʻana i ka palaho. ʻO ke kino o kakiwikā pepeke(me ka uhi valve) e noho ana i ka hapa nui o ke kaumaha o ka valve a pili pinepine ia me ka medium, no laila ua koho pinepine ʻia ka valve butterfly mai ka mea o ke kino.

ʻElua wale nō ʻano o ka pala o ke kino valve onā kiwikā pepeke, ʻo ia hoʻi ka palaho kemika a me ka palaho electrochemical. Hoʻoholo ʻia kona helu palaho e ka mahana, ke kaomi, nā waiwai kemika o ka medium, a me ke kūpaʻa ʻana o ka mea kino valve. Hiki ke hoʻokaʻawale ʻia ka helu palaho i ʻeono pae:

1. Ke kūpaʻa piha ʻana i ka pala: ʻoi aku ka liʻiliʻi o ka pala ma mua o 0.001 mm/makahiki;

2. Kū'ē loa i ka pala: ka helu pala 0.001-0.01 mm/makahiki;

3. Ke kūpaʻa ʻana i ka pala: ka helu pala 0.01-0.1 mm/makahiki;

4. Ke kūpaʻa kiʻekiʻe o ka palaho: ka nui o ka palaho 0.1-1.0 mm/makahiki;

5. Ke kūpaʻa ʻino ʻole: ka nui o ka pala 1.0-10 mm/makahiki;

6. Ke kūpaʻa ʻole i ka pala: ʻoi aku ka nui o ka pala ma mua o 10 mm/makahiki.

Pehea e pale aku ai i ka palaho onā kiwikā pepeke?

ʻO ke kū'ē ʻana i ka palaho o ke kino valve o ka valve butterfly ma muli nui o ke koho pololei ʻana o nā mea. ʻOiai he waiwai nui ka ʻike e pili ana i ka kū'ē ʻana i ka palaho, ʻaʻole maʻalahi ke koho i ka mea kūpono, no ka mea, he paʻakikī loa ka pilikia o ka palaho, no ka laʻana, he mea hōʻino loa ka waikawa sulfuric i ke kila ke haʻahaʻa ka nui, a ke kiʻekiʻe ka nui, hana ia i ke kila e hana i kahi kiʻi passivation, hiki ke pale i ka palaho; Hōʻike wale ʻia ka hydrogen he mea hōʻino loa i ke kila ma ke kiʻekiʻe o ka mahana a me ke kaomi, a ʻaʻole nui ka hana palaho o ke kinoea chlorine ke maloʻo, akā ikaika loa ka hana palaho ke 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 palaho, akā e noʻonoʻo pū i nā mea e like me ke kū'ē ʻana i ke kaomi a me ka mahana, inā he kūpono i ka hoʻokele waiwai, a inā he maʻalahi ke kūʻai. No laila pono ʻoe e makaʻala.

1. ʻO ka lua, ʻo ia ke hana i nā hana uhi, e like me ke kēpau, ka alumini, nā palakiko ʻenekinia, ka laholio kūlohelohe a me nā laholio synthetic like ʻole. Inā ʻae nā kūlana waena, he ala mālama kēia.

2. ʻO ke kolu, i ka wā ʻaʻole kiʻekiʻe ke kaomi a me ka mahana, hiki i ka mea nui o ka valve pulelehua i uhi ʻia i ka fluorine ke lilo i mea kūpono loa i ka pale ʻana i ka pala.

3. Eia kekahi, ua ʻinoʻino ʻia ka ʻili o waho o ke kino valve e ka lewa, a ua pale ʻia ka mea hao ductile e ka uhi nickel.

E hoʻomaka koke ana ʻo TWS i kahi laina huahana anti-corrosion hou, e uhi ana i kahi ākea o nā hopena valve e like menā kiwikā pepeke, nā kiwikā puka, nā kiwikā nānāa me nā kiwikā poepoe, a pēlā aku. Hoʻohana kēia moʻo o nā huahana i ka ʻenehana pale ʻino holomua a me nā kaʻina hana mālama mea kūikawā e mālama i ka hana sila maikaʻi loa a me ke kūpaʻa hana ma lalo o nā kūlana hana koʻikoʻi. Ua kūpaʻa mākou i ka hāʻawi ʻana i nā mea kūʻai aku me nā huahana valve ʻoihana paʻa, e hoʻolōʻihi nui ana i ke ola lawelawe o nā lako, e hōʻemi ana i nā kumukūʻai mālama i ke ola holoʻokoʻa.laulākaʻapuni, a me ke kōkua ʻana i nā mea kūʻai aku e hoʻokō i nā hoʻoholo kūʻai waiwai kiʻekiʻe.
