I kēia mau lā i hala iho nei, ke hana nei kā mākou hale hana i kahi hui kila kilanā puka komo, he ʻano hou ia o ka puka pā i hoʻopili ʻia i hana ʻia e kā mākou hale hana, me ka hoʻohana ʻana i ʻelima ʻenehana kūlou, deformation liʻiliʻi a me ka sila ikaika. Ma hope o kapā penikalaI ka wā e hoʻopili ai i ka valve, e loaʻa kahi hopena ʻeleʻele, e hoʻopilikia ana i ke ʻano, ʻo ia hoʻi ma muli o ka hopena o ka mahana kiʻekiʻe i ka wā o ke kaʻina hana hoʻopili, no laila e oxidizes ka metala ma luna o ka valve, e hana ana i kahi kiʻiʻoniʻoni oxide ʻeleʻele.

Eia ka mea e wehewehe ai i ke ʻano pickling e hana ai me ka blackening:

Hoʻohana ka hale hana ʻo Jinbin i ke ʻano holoi electrolytic pickling, me ka hoʻohana ʻana i ka hana electrolytic a me ka pala kemika o ka waikawa e wehe i ka ʻili ʻokikene ʻeleʻele ma ka ʻili o ka valve. I ke kaʻina hana electrolytic, hana ka valve ma ke ʻano he anode, a ua hoʻohuihui ʻia ka ʻili ʻokikene ma ka ʻili metala ma lalo o ka hana o ke au ma hope o ka hoʻoikaika ʻia ʻana, e hana ana i nā ion metala hiki ke hoʻoheheʻe ʻia i loko o ka hopena waikawa, a pēlā e wikiwiki ai ka wehe ʻana o ka ʻili ʻokikene. I ka manawa like, hana kemika nā ion hydrogen i loko o ka waikawa me nā oxides metala e hoʻoheheʻe iā lākou a hoʻokō i ke kumu o ka hoʻomaʻemaʻe ʻana i ka ʻili o ka valve.

Ke kahe o ke kaʻina hana pickling:

1. Ka mālama mua ʻana o ka ʻili: Ma mua o ka pickling, pono e hana mua i ka mālama mua ʻana o ka ʻili ma ka valve, e like me ka hoʻohana ʻana i nā ʻano hana mechanical e wehe ai i ka aila, ka ʻōpala, ka slag welding a me nā mea haumia ʻē aʻe ma ka ʻili e hōʻoia i ka hiki i ka waikawa ke hoʻopili piha i ka kiʻiʻoniʻoni oxide a hoʻomaikaʻi i ka hopena pickling.

E hoʻouka a kau pololei i ka valve ma ke kūlana anode o ka mea pickling electrolytic e hōʻoia i ka maikaʻi o ka hoʻopili ʻana ma waena o ka valve a me ka electrode a hiki ke hoʻokaʻawale like ʻia ke au ma ka ʻili o ka valve.

2. E hoʻomākaukau i ka hopena pickling: E ​​koho i ke ʻano waikawa kūpono a me ka nui e like me ka mea a me ke kekelē oxidation o ka valve. ʻO nā waikawa maʻamau ka sulfuric acid, nitric acid, hydrochloric acid, a pēlā aku, a i ʻole ka hui ʻana o lākou. No ka laʻana, no nā valves kila kila, hoʻohana pinepine ʻia ka hui ʻana o ka nitric acid a me ka hydrofluoric acid. I ka hoʻonohonoho ʻana i ka waikawa, pono e hahai pono i nā kaʻina hana, e hoʻolohe ana i ka nui o ka waikawa, ka mahana a me ka nui o nā mea hoʻohui a me nā palena ʻē aʻe.

3. Hoʻopili uila: E ninini i ka waikawa i hoʻonohonoho ʻia i loko o ke kelepona electrolytic, e hoʻā i ka lako mana electrolytic, a kāohi i ka nui o ke au kūpono, ka manawa electrolytic a me ka mahana o ka waikawa a me nā palena ʻē aʻe. Ma ke ʻano laulā, ʻo ka nui o ke au a me ka lōʻihi o ka manawa electrolytic, ʻoi aku ka maikaʻi o ka hopena wehe ʻana o ka ʻili oxide, akā i ka manawa like, pono e mālama pono e pale aku i ka pickling nui e alakaʻi ana i ka pala nui o ka metala ʻili valve. Hoʻomalu pinepine ʻia ka mahana o ka waikawa i loko o kahi pae, ʻo ke kiʻekiʻe loa o ka mahana e wikiwiki ai ka volatilization a me ka decomposition o ka waikawa, e hoʻopilikia ana i ka hopena pickling, a ʻo ka mahana haʻahaʻa loa e lohi ai ka wikiwiki o ka hopena.

4. Holoi wai: Ma hope o ka pau ʻana o ka pickling electrolytic, e wehe i ka valve mai ka waikawa a hoʻokomo koke i loko o ka wai maʻemaʻe e kahe ana no ka holoi ʻana e hoʻopau loa i ke koena waikawa a me nā huahana hopena ma ka ʻili o ka valve. Pono ka manawa holoi a me ka wikiwiki o ke kahe ʻana o ka wai e hōʻoia i ka hiki ʻana o ka pH o ka ʻili o ka valve i ke kūlike ʻole a pale i ke koena waikawa mai ka hoʻoulu ʻana i ka pala lua i ka valve.

5. Ma hope o ka mālama ʻana: Hiki ke mālama hou ʻia ka kiwikā ma hope o ka holoi ʻana e like me ka mea e pono ai, e like me ka mālama passivation, ka mālama anti-rust, a pēlā aku, e hoʻomaikaʻi i ke kūpaʻa ʻana i ka pala a me ke ola lawelawe o ka kiwikā. 

ʻO Jinbin Valve ma ke ʻano he mea hana penstock, e hana ana i nā ʻano kiwikā metallurgical āpau, ka puka penstock kila kila, nā kiwikā puka nui, nā kiwikā pulelehua, a pēlā aku, inā he mau pono pili kāu, e waiho i kahi leka ma lalo a i ʻole leka uila e hoʻokaʻaʻike mai iā mākou, e loaʻa iā ʻoe kahi pane i loko o 24 mau hola, e kakali ana i ka hana pū ʻana me ʻoe!
