Zvakajairika kupomha zvinwiwa
Mvura yakachena
Kuunza zvese pombi bvunzo curves kune yakajairika base, pombi maitiro yakavakirwa pamvura yakajeka paAmberion tembiricha (kazhinji 15 ℃) ine density ye 1000 kg / m³.
Izvo zvinonyanya kujairika zvekuvakwa kwemvura yakachena zvese zvinokanda dare rekuvaka kana kukanda simbi dzakasungirirwa kunze kwenyika, kana mvura inonyatsotsanangurwa seyakarerekera neiyo hurukuro ye1 isina solids iripo,Kupera Suction Pumpsuye yakatwasukakupatsanura casing pumpszvinonyanya kushandiswa. Kana misoro yakakwirira yekudzingwa inodiwa, maratidziro akawanda emhando.
Kana magadziri anogumira pombi imba yekugara imba, vertical zvikamu zveimwe yakasanganiswa kuyerera, axial kana turbine mhando pumps inoshandiswa.
Mvura yegungwa seyakaora pakati
Mvura yegungwa ine huwandu hwemunyu wemunyu wemasikati anenge 25 g / ℓ. Inenge makumi manomwe neshanu muzana ezvemunyu zviri mukati meSodium chloride nacl. Iyo PH-kukosha kwemvura yegungwa kazhinji iri pakati pe7,5 nemakumi masere. Mukuenzana nemhepo, iyo okisijeni zvirimo musi wa15】 iri anenge 8 mg / ℓ.
Deadsed Gungwa Mvura
Mune zvimwe zviitiko, mvura yegungwa yakadonha nemakemikari kana phyy-ally. Nekuda kweizvi, kutsamwa kunoenderana zvakanyanya. Panyaya yemakemikari degasimation, inofanira kucherechedzwa kuti Dhigirii rinotora nguva. Nekuda kweizvozvo, zvakakosha kuti mashandiro emagetsi, kureva kubviswa kweokisijeni, wapedzwa zvakakwana mvura yegungwa isati yasvika pombi.
Kuchengetwa kunofanirwa kuve kwakanyengedzwa mukushanda-kuhurongwa kunogona kuitika kuburikidza nekusagadzikana kwemhepo. Kunyangwe iyo inruses ishoma nguva yekuchenjera, kukuvadzwa kune izvo zvinhu zvinogona kuitika nekukurumidza pasi pemamwe mamiriro kana kuvapo kweokisijeni hakuonekwe kana izvo zvishandiso zvakasarudzwa. Kana iyo inruses yeokisijeni isingakwanisi kubviswa panguva yekuvhiya pombi, zvinowanzofungidzirwa kuti mvura yegungwa ine oxygen.
Brackish mvura
Izwi rekuti 'mvura yeBrackish' inounza mvura nyowani yakasvibiswa nemvura yegungwa. Sekusarudza kwezvinhu zvine chekuita nezvakareva, iwo mataurirwo mamwechete ekutakura kwekufambisa kwemvura yeBrackish seyenzi dzemvura. Mukuwedzera, mvura yeBrackish kazhinji ine Amonia uye / kana hydrogen sulphide. Kunyangwe iyo yakaderera yemukati yehydrogen sulphide, kureva mudunhu remamirimita mashoma pane litita, inokonzeresa kuwedzera kwehutsinye.
Mvura yegungwa kubva pasi pevhu zvinyorwa
Mvura ine munyu kubva pasi pevhu inowanzove neyakawandisa munyu wemunyu pane mvura yemugungwa, kazhinji kazhinji ichava makumi matatu muzana, kureva pasi peiyo solubility muganho. Pano zvakare, munyu unowanzoitika ndidzo huru. Iyo PH kukosha inowanzo kuve yakaderera (pasi kusvika pa4), kureva kuti mvura iri aciduusous. Ipo zviripo zveokisijeni zvakanyanyisa kana kunyange pasina chinhu, iyo H₂s zvemukati inogona kuwanda kwemamirioni mashoma emamirioni pa litita.
Solidution yemunyu yemunyu ine h₂s inokatyamadza uye inodaidzira zvinhu zvakakosha.
Semhedzisiro yeiyo yakakwirira yemunyu yezvinyorwa uye zvichienderana nemamiriro ekushanda, munhu anofanira kutarisira imwe nhanho yemunyu wokumwe. Muzviitiko zvakadaro, zviyero zvakakodzera zvinofanirwa kutorwa mukuremekedza kwekugadzirwa, kushanda uye kusarudzwa kwechinyorwa.
Corrosion mumvura yegungwa
Zvinyorwa zvinoshanda hazvina kungoita kuratidza kuramba kwakanyanya kupesana nekuparadzaniswa kwakawanda, asi zvakare kurwisa koposo yemuno kunyanya kudzikisira uye crevice corrosion. Yakadaro Corrosion Phenomena inosangana zvakanyanya nekuzvisarudzira Ferro Alloys (Stainless Steels). Zvinotodaidzwa kuti 'zvinomira' pumps, izvo zvinongopindwa nemari chete, mhanya nengozi yekumanikidza kugadzirisa; Mafashama nemvura nyowani isati yasvika nguva yekuvhara-pasi kana nguva yekutanga inotangira inoonekwa zvakanaka.
Variousgungwa mvura pombizvikamu zvinofanirwa kugadzirwa kubva kune zvigadzirwa zvemhando imwechete kuitira kudzivirira genilic corrosion. Mutsauko ungangosarudzika pakati pezvishandiso zvega ndezvekunyanyisa sezvazvinogona. Nekudaro, kana zvisina kufanana nemidziyo inofanira kushandirwa zvikonzero zvekugadzira, nzvimbo dzesimbi isinganyanye kusangana nemvura inofanira kuve yakakura mukuenzanisa neayo simbi yakanaka. Mufananidzo 5 unopa ruzivo nezve njodzi yegungwa kana mhando dzakasiyana dzemhando dzakasanganiswa.
Yakakwira Veloces inogona kutungamira kuErosion Corrosion. Migumisiro yacho inowedzera kuwanda, iyo inonyanya kurwisa svikiro, uye yakakwira velocity yayo. Ipo kuyerera kwehuwandu kunokanganisa maitiro emarara uye nickel alloys kune degree diki, chinzvimbo chakadzoreredzwa uko kune zvisina kufanira zvinhu zvinoshamisa uye alloys the they Mufananidzo 6 unopa ruzivo rwakakodzera pane pesvedzero yemari yekuyerera. Kufunga kwakakodzera kunofanirwa kupihwa ipapo sekuti svikiro ine oksijeni kana h₂s. Huwandu hukuru hweH₂s dzinowanzo bvisa kuvapo kweokisijeni; Muzviitiko zvakadaro, svikiro iri zvishoma acidhulous, pasi kune pH ye4.
Maitiro ekuita
Tafura 1 inoita mazano ezvekushandisa kwepombi kana kusanganisa kwavo. Kunze kwekunge zvataurwa neimwe nzira, ruzivo rwunotevera runoshanda kumvura yegungwa isina chero h₂s zvemukati.
Isina kugadziriswa simbi uye yakakanda simbi
Simbi isina kugadziriswa haina kukodzera kumvura yegungwa, kunze kwekunge ichipiwa neyakakodzera kuunganidzwa. Cast simbi inongove ichishandiswa kune yakaderera velocities (zvinokwanisika kumisasa); Mune ino kesi yakajairika cathodic kuchengetedzwa kweimwe internals inofanira kushandirwa.
Austenitic ni-castings
Ni-Ramba 1 uye 2 zvinongokodzera chete pakati nepakati velodhiyo (kusvika pamakore makumi maviri nemashanu.
