Kutshanje, umzi-mveliso wethu uvelisa inqwaba yentsimbi engagqwaliyoamasango okucoca, oluluhlobo olutsha lwesango elixhonywe eludongeni elenziwe ngumzi-mveliso wethu, kusetyenziswa iteknoloji yokugoba emihlanu, ukuguqulwa okuncinci kunye nokuvalwa okuqinileyo.ipenstock eludongeniXa kudityaniswa ivalvu, kuya kubakho impendulo emnyama, echaphazela inkangeleko, ikakhulu ngenxa yempembelelo yobushushu obuphezulu ngexesha lenkqubo yokudityaniswa, ukuze isinyithi esikumphezulu wevalvu sinyibilike, senze ifilimu ye-oxide emnyama.

Oku kulandelayo kuchaza indlela yokucola ukuze kujongwane nobumnyama:

Umzi-mveliso weJinbin usebenzisa indlela yokuhlamba nge-electrolytic, usebenzisa isenzo se-electrolytic kunye nokubola kwe-asidi ngamakhemikhali ukususa ifilimu ye-oxide emnyama kumphezulu wevalvu. Kwinkqubo ye-electrolytic, ivalvu isebenza njenge-anode, kwaye ifilimu ye-oxide kumphezulu wesinyithi ifakwa kwi-ion phantsi kwesenzo sombane emva kokuba inikwe amandla, okwenza ii-ion zesinyithi ezinyibilikayo kwisisombululo se-asidi, ngaloo ndlela kukhawuleziswe ukususwa kwefilimu ye-oxide. Kwangaxeshanye, ii-ion ze-hydrogen kwi-asidi zisabela ngokwekhemikhali kunye nee-oxide zesinyithi ukuze zinyibilike kwaye zifezekise injongo yokucoca umphezulu wevalvu.

Ukuhamba kwenkqubo yokukha:

1. Unyango lwangaphambi komphezulu: Ngaphambi kokuba kugalelwe i-pickling, kuyimfuneko ukwenza unyango lwangaphambi komphezulu kwivalvu kuqala, njengokusebenzisa iindlela zoomatshini ukususa ioyile, umhlwa, i-welding slag kunye nezinye izinto ezingcolileyo kumphezulu ukuqinisekisa ukuba i-asidi inokuchukumisa ngokupheleleyo ifilimu ye-oxide kwaye iphucule isiphumo sokugalelwa i-pickling.

Faka kwaye uxhome ivalvu ngokuchanekileyo kwindawo ye-anode yesixhobo sokugaya i-electrolytic ukuqinisekisa ukuba unxibelelwano phakathi kwevalvu kunye ne-electrode lulungile kwaye umbane unokusasazwa ngokulinganayo kumphezulu wevalvu.

2. Lungisa isisombululo sokucola: Khetha ifomula ye-asidi efanelekileyo kunye noxinzelelo ngokwezinto ezisetyenzisiweyo kunye nobungakanani be-oxidation yevalvu. Ii-asidi eziqhelekileyo yi-sulfuric acid, i-nitric acid, i-hydrochloric acid, njl.njl., okanye umxube wazo. Umzekelo, kwiivalvu zentsimbi engatyiwayo, umxube we-nitric acid kunye ne-hydrofluoric acid uhlala usetyenziswa. Xa ulungiselela i-asidi, kuyimfuneko ukulandela ngokungqongqo iinkqubo zokusebenza, unike ingqalelo kuxinzelelo lwe-asidi, ubushushu kunye nobungakanani bezongezo kunye nezinye iiparameter.

3. Ukucoca nge-electrolytic: Galela i-asidi emiselweyo kwiseli ye-electrolytic, uvule umbane we-electrolytic, kwaye ulawule uxinano lwangoku olufanelekileyo, ixesha le-electrolytic kunye nobushushu be-asidi kunye nezinye iiparameter. Ngokubanzi, okukhona uxinano lwangoku lukhulu kwaye ixesha le-electrolytic lide, kokukhona isiphumo sokususa ifilimu ye-oxide singcono, kodwa kwangaxeshanye, kufuneka kuthathwe unonophelo ukuze kuthintelwe ukucoca ngokugqithisileyo okukhokelela ekungcoleni okugqithisileyo kwentsimbi yomphezulu wevalvu. Ubushushu be-asidi buhlala bulawulwa ngaphakathi koluhlu oluthile, ubushushu obuphezulu kakhulu bunokukhawulezisa ukuguquguquka kunye nokubola kwe-asidi, okuchaphazela isiphumo sokucoca, kwaye ubushushu obuphantsi kakhulu bunokubangela ukuba izinga lokuphendula licothe kakhulu.

4. Ukuhlamba ngamanzi: Emva kokuba kugqityiwe ukucoca nge-electrolytic, susa ivalvu kwi-asidi uze uyifake ngokukhawuleza emanzini acocekileyo ahambayo ukuze ihlanjwe ukuze kususwe ngokupheleleyo i-asidi eseleyo kunye neemveliso zokusabela kumphezulu wevalvu. Ixesha lokuhlamba kunye nesantya sokuhamba kwamanzi kufuneka zanele ukuqinisekisa ukuba i-pH yomphezulu wevalvu ifikelela kwi-neutral kwaye ithintele i-asidi eseleyo ekubeni ibangele ukubola kwesibini kwivalvu.

5. Emva konyango: Ivalvu emva kokuhlamba ingaphathwa ngakumbi njengoko kufuneka, njengonyango lokungashukumi, unyango lokulwa nomhlwa, njl.njl., ukuphucula ukumelana nokugqwala kunye nobomi benkonzo yevalvu. 

I-Jinbin Valve njengomvelisi we-penstock, evelisa zonke iintlobo zeevalvu ze-metallurgical, isango le-penstock lentsimbi engagqwaliyo, iivalvu zesango elikhulu, iivalvu zebhabhathane, njl.njl., ukuba uneemfuno ezifanayo, nceda ushiye umyalezo apha ngezantsi okanye usithumelele i-imeyile, uya kufumana impendulo kwiiyure ezingama-24, ujonge phambili ekusebenzeni nawe!
