Ulwelo oluqhelekileyo lokupelwa
Amanzi acocekileyo
Ukuzisa yonke i-pump yovavanyo kwisiseko esiqhelekileyo, iimpawu zempompo zisekwe kumanzi acocekileyo kubushushu obucacileyo (ngokubanzi i-15 ℃) ngoxinano lwe-1000 kg / m³.
Ezona zinto ziqhelekileyo zokwakhiwa kwamanzi acocekileyo kukwakhiwa kukwakhiwa kwentsimbi okanye i-iron cheng efakwe kwi-Bronze Enetses, xa icaciswe ngamanzi acocekileyo,Ukuphelisa impompo yokuncancisakunye ne-ethe tyeYahlula-hlula i-pumpszihlala zisetyenziswa. Xa iintloko eziphezulu zokuphelisa ziyafuneka, kusetyenziswa ukhetho lwe-Pumps.
Xa abaqulunqileyo banqunyelwe kwindawo yendlu ye-Pump, iiyunithi ezithe nkqo zendlela yokuhamba okuxubeneyo, i-axial okanye i-tump ye-pumpline okanye i-tump ye-pumple ye-tump.
Amanzi olwandle njengendawo ephakathi
Amanzi olwandle anomxholo wetyuwa epheleleyo malunga ne-25 g / ℓ. Malunga neepesenti ezingama-75 zomxholo wetyuwa yi-sodium chloride nacl. Ixabiso le-pH-Amanzi olwandle ahlala phakathi kwe-7,5 ne-8,3. Ukulingana nemozulu, umxholo weoksijini kwi-15 ℃ imalunga ne-8 mg / ℓ.
Amanzi olwandle akhutshelweyo
Kwiimeko ezithile, amanzi olwandle adityaniswe ngokukhawuleza okanye i-phy-ally. Ngenxa yoku, uburharha buthathaka kakhulu. Kwimeko yokuqatyathwa kwamachibi amachiza, kuya kufuneka kuqatshelwe ukuba ukudinwa kuthatha ixesha. Ngenxa yoko, kubaluleke kakhulu ukuba umsebenzi wokukhubeka, okt ukususwa kweoksijini, igqitywe ngokupheleleyo ngaphambi kokuba amanzi olwandle angena kwimpompo.
Kufuneka kuthathelwe ingqalelo kwi-Aeration-orenition inokwenzeka nge-inrush yomoya. Nangona i-inrhesh inobulumko ixesha elinobulumko, ukonakaliswa kwezinto kunokwenzeka ngokukhawuleza phantsi kweemeko ezithile ukuba ubukho beoksijini ayiqwalaselwa xa zikhethwayo izixhobo. Ukuba i-inrbus yeoksijini ayinakukhutshelwa ngaphandle kwempompo yokusebenza, kufuneka icingelwe ngokubanzi ukuba amanzi olwandle aqulethe ioksijini.
Amanzi aqhekezayo
Ibinzana 'lamanzi ane-Brackesh' amanzi anamanzi amatsha adityaniswe ngamanzi olwandle. Ngokukhethekile ekukhetheni kwezinto ezichaphazelekayo, imiyalezo efanayo ifaka isicelo sothutho lwamanzi atyhafileyo njengaManzi olwandle. Ukongeza, amanzi aqhekekileyo aqulathe i-ammonia kunye / okanye i-hydrogen sulphde. Nditsho nomxholo ophantsi we-hydrogen sulphide, okt kwingingqi yee-milligram ezimbalwa ngelitha nganye, zibangela ukwanda okubizwe ngobukrakra.
Amanzi olwandle avela kwimithombo engaphantsi komhlaba
Amanzi anetyiwa avela kwimithombo yomhlaba ngaphantsi ahlala enomxholo ophezulu wetyuwa kunamanzi olwandle, ahlala malunga ne-30%, okt phantsi komda wobungakanani. Apha kwakhona, ityuwa eqhelekileyo yeyona ndawo iphambili. Ixabiso le-pH lihlala liphantsi (ezantsi ukuya kuthi ga kwi-4), oko kukuthi amanzi angqine. Ngelixa umxholo weoksijini uphantsi kakhulu okanye ungabikho, umxholo we-H₂S unokufumana isixa semiligram eneemiligramu ezimbalwa ngelitha nganye.
Ezo zisombululo zetyuwa ezinjalo ezinamatyala ane-H₂S zivele kakhulu kwaye zibize izinto ezizodwa.
Ngenxa yomxholo ophezulu wetyuwa kwaye kuxhomekeka kwiimeko zokusebenza, umntu kufuneka alindele ukuba inqanaba elithile le-tyheci. Kwiimeko ezinjalo, ukubalalela ezifanelekileyo kufuneka kuthathwe ngokubhekisele kuyilo, ukusebenza kunye nokukhethwa kwezinto.
I-Corosion kumanzi olwandle
Izinto ezisetyenzisiweyo azisebenzi kuphela ukubonisa ukunganyangeki okuphezulu kwi-corosion ye-iyuniform, kodwa kunye nokunxibelelana kwendawo ekuqulunqweni nasekuhlaleni. I-Prerosion enjalo i-phenomena inamava ngokukhethekileyo i-froads ye-ferrols (izistim ezingenakwenzeka). Ukubizwa ngokuba 'kukulinda', nto leyo isebenza ngokuthintela, qhuba umngcipheko wesimo sokuma; Izikhukula ngamanzi amatsha ngaphambi kwexesha elivaliweyo okanye ixesha lokuqalisa kwamaxesha ngamaxesha kuthathwa njengeluncedo.
EzahlukeneyoImpompo yamanzi olwandleIzinto kufuneka zenziwe kwizixhobo zohlobo olufanayo ukuze kuthintelwe ukuvela kwe-Galvanic. Umahluko onokubakho phakathi kwezixhobo zomntu ngamnye kukuphantsi kangangoko kunokwenzeka. Nangona kunjalo, ukuba ngokungafaniyo nezixhobo kufuneka ziqeshe izizathu zoyilo, umphezulu wensimbi engabonakaliyo ekunxibelelaneni namanzi kufuneka ube nkulu xa uthelekisa nezona zentsimbi entle. Umzobo o-5 ubonelela ngolwazi malunga nengozi ye-Galvanic uCorrosion xa izixhobo zohlobo ezahlukeneyo zidityanisiwe.
I-velocies ephezulu ingakhokelela ekususweni kwe-erosion. Iziphumo ziya kuqhubeka zisiba nzima, kokukhona krwada ngakumbi, kwaye uphakame phezulu. Ngelixa ireyithi yokuhamba ichaphazela indlela yokuziphatha kwezinto ezingenasiseko kunye ne-nickel ye-walting kwisidanga esincinci, isikhundla sibuyiselwe apho izinto ezinobunzima obufana nazo kwaye zibandakanyekile. Umzobo 6 ubonelela ngolwazi olufanelekileyo kwimpembelelo yokuhamba kweerhafu. Kuya kuthathelwa ingqalelo ukuba inikwe khona malunga nokuba iphakathi iqulethe ioksijini okanye i-H₂S. Isixa esikhulu se-H₂S sidla ngokukhuphela ubukho beoksijini; Kwiimeko ezinjalo, i-Medium ine-acidiaus, ezantsi kwi-hlebe 4.
Ukuziphatha kwezinto
Itheyibhile 1 yenza izindululo zezixhobo zempompo okanye indibaniselwano yazo. Ngaphandle kokuba kuchazwe ngenye indlela, le ngcaciso ilandelayo isebenza kumanzi olwandle ngaphandle komxholo we-H₂S.
Intsimbi engathandekiyo kunye nentsimbi
Intsimbi engathandekiyo ayifanelekanga ukuba ingabi namanzi olwandle, ngaphandle kokuba kubonelelwe ngokukhusela okufanelekileyo. I-iron yentsimbi isetyenziselwa i-velocies esezantsi (inokwenzeka kwi-casngs); Kule meko ukhuseleko lwe-cathodic oluqhelekileyo lwezinye izinto kufuneka luqeshwe.
I-Austetitic Nidings
I-NI-Counit 1 kunye ne-2 ilungele kuphela i-velousis ephakathi (ukuya kuthi ga kwi-20 m / s).
I-Galvanic i-comrosion emanzini olwandle nge-5-30 ℃
Ixesha lasemva: Mar-11 ukuya kwi-1125
