I-Corrosion inokohlulwa ibe yikhemikhali kunye ne-electrochemical corrosion

Ukunxiba imiba yoyilo lwempompo oluludaka Umenzi wempompo yokunxiba Uninzi lokunxiba imiba yoyilo lwempompo eludaka , kunye namalungu ahlukeneyo kunye neendawo ezahlukeneyo zeendlela zokunxiba azifani , kodwa ngokubanzi zinokushwankathelwa ngokweendidi ezintathu:

I-1 Ukhukuliseko : Kumenzi wempompo ye-slurry ngexesha lokusebenza, ulwelo ukuya kumasuntswana aqinileyo aqhutywe kwinqanaba lokuhamba phezu kwelungu leempembelelo, okubangelwa ukulahlekelwa kwezinto.Ngokohlahlelo lokungaphumeleli kwecandelo lokunxiba indlela yokukhukuliseka komhlaba inokwahlulwa ibe kukusikwa kokusikwa kunye nokunxitywa kwe-deformation kunye nokudinwa kokusikwa + ukuguqulwa okudibeneyo.

Umonakalo we-2 cavitation: Ngexesha lokusebenza kwempompo, amacandelo okuhamba kwingingqi yendawo ( ngokuqhelekileyo kwi-inlet impeller kamva ), ngenxa yesizathu esithile, ulwelo lufakwe ngexesha apho uxinzelelo olupheleleyo lwehla kuxinzelelo lomphunga lobushushu, apho ulwelo luqala ukujika lube ngumphunga ukwenza umphunga , ukubunjwa kwamaqamza .Lamaqamza anolwelo oluya phambili , ukuya kuxinzelelo oluphezulu , amaqamza adilika ngokumangalisayo ancitshiswe ngokulinganayo .Okwangoku kwi-bubble condensation, iincinci ze-liquid kwi-high speed filling voids, kwaye zibe nefuthe elinamandla kwi-metal surface.Le metal surface spalling ngenxa yempembelelo yokudinwa , okukhokelela ekulahlekeni kwezinto eziphathekayo, umphezulu wesinyithi onzima obonisa i-honeycomb.Iingxenye ze-cavitation zivame ukuvela kwi-impeller outlet kunye ne-volute inlet.

I-3 i-corrosive wear: Xa i-transmission medium ine-pH ethile,umenzi wempompo enodakaAmalungu okuqukuqela ayakwenzeka ukunxitywa okudlekayo , oko kukuthi ilahleko yezinto eziphathekayo zenzeka phantsi kwentshukumo edityanisiweyo yokukhula nokuguga .

I-Corrosion inokohlulwa ibe yikhemikhali kunye ne-electrochemical corrosion.I-Chemical corrosion yentsimbi kunye ne-media media ye-liquid impendulo ngokuthe ngqo eshiya ilahleko yesinyithi, i-electrochemical corrosion kwindawo yolwelo yindima yomgangatho wesinyithi ukwenza ibhetri encinci ishiya ilahleko yezinto.Ekubeni ukusetyenziswa kwangempela kwezinto zetsimbi zizinto ze-polycrystalline ze-multiphase, ngoko ke, i-corrosion yokuqala, i-electrochemical corrosion, ngokukodwa i-crystal boundary corrosion, i-intergranular cracks yenziwa imiphezulu yesinyithi, kwaye ukwahlula i-granular corrosion okanye, inkxaso elahlekileyo, ngoko iya kuvela. kukhukuliseko lwenzeka amasuntswana aqinileyo;Ngelixa ukhuhla amasuntswana aqinileyo , kunye nentsimbi yomphezulu wentsimbi ngenxa yomaleko wokudlula uyakhuhlwa ukuvelisa ulwelo oluphakathi ngokudibana nomphezulu wesinyithi ukunyusa umhlwa omtsha .Umenzi wempompo ye-slurry kuhlalutyo lokungaphumeleli kobukho be-phenomenon ifunyenwe i-corrosion.
