Indlela yokukhetha impompo yeekhemikhali?

Imimandla eyahlukeneyo, imidiya eyahlukeneyo, izinto ezahlukeneyo ... Kubonakala ngathi akulula kakhulu ukukhetha impompo yeekhemikhali ezifanelekileyo. Umpompo ongalunganga ungonakalisa izixhobo ubuncinci, kwaye ubangele iingozi okanye iintlekele kakhulu!

Namhlanje i-Shuangbao iya kukwazisa namhlanje ulwazi malunga nokukhethwa kohlobo olusekelwe kumava orhwebo adlulileyo, ngethemba lokuba luncedo kuthi abasebenzi beekhemikhali.

Imigaqo yokukhetha impompo yeekhemikhali:
   1. Yenza uhlobo kunye nokusebenza kompompo okhethiweyo ukuhlangabezana neemfuno zeeparitha zenkqubo ezifana nokuhamba kwesixhobo, ukuphakamisa, uxinzelelo, ukushisa, ukuhamba kwe-cavitation, kunye nokufunxa.
   2. Kufuneka ukuhlangabezana neemfuno zeempawu eziphakathi.
   Iimfuno zeempawu eziphakathi kufuneka zifezekiswe. Kwiimpompo ezihambisa imidiya enokutsha, eqhumayo, eyityhefu okanye enexabiso, iimpompo ezithembekileyo zeshaft okanye iimpompo ezingavuzi ziyafuneka, njengeempompo zemagnethi zokuqhuba (akukho zitywina zeshaft, ukuhanjiswa kwemagnethi okukodwa). Kwiimpompo ezinemithombo yeendaba ezitshabalalisayo, iinxalenye ze-convection kufuneka zenziwe ngezinto ezichasene ne-corrosion, ezifana neepompo ze-fluoroplastic corrosion-resistant. Kwiimpompo ezihambisa imidiya equkethe iinqununu eziqinileyo, iinqununu ze-convection zifuneka ukuba zenziwe ngezinto eziphathekayo, kwaye isitywina se-shaft kufuneka sihlanjwe ngolwelo olucocekileyo ukuba kuyimfuneko.
   3. Ukuthembeka okuphezulu komatshini, ingxolo ephantsi kunye nokungcangcazela.
   4. Qwalasela ixabiso legalelo lokuthengwa kwempompo ngokubanzi.
   Imigaqo, izakhiwo zangaphakathi, kunye namacandelo eempompo ezithile ziyafana, kwaye umahluko omkhulu ubonakaliswa ekukhethweni kwezinto eziphathekayo, ukusetyenzwa kunye nomgangatho wamacandelo. Ukwahluke kwezinye iimveliso, ukungafani kweendleko zamacandelo epompo kubaluleke kakhulu, kwaye i-gap yexabiso lamakhulu okanye amawaka amaxesha abonakaliswe ekusebenzeni kunye nobomi benkonzo yemveliso.

 
Isiseko sokukhetha iimpompo zekhemikhali:
   Isiseko sokukhetha iimpompo zekhemikhali kufuneka zisekelwe kwinkqubo yokuhamba, unikezelo lwamanzi kunye neemfuno zokuhambisa amanzi, kwaye zithathelwe ingqalelo kwiinkalo ezintlanu, ezizezi: umthamo wokuhambisa ulwelo, ukunyuswa, iipropati zolwelo, ulungelelwaniso lwemibhobho, kunye neemeko zokusebenza.
   1. Ukugcwala kwabantu
   Isantya sokuhamba yenye yedatha ebalulekileyo yokusebenza yokukhethwa kwempompo, ehambelana ngokuthe ngqo nomthamo wokuvelisa kunye nokuhanjiswa kwesixhobo sonke. Ngokomzekelo, kwinkqubo yoyilo lweziko loyilo, imilinganiselo emithathu yokuhamba kweepompo eziqhelekileyo, ezincinci kunye ezinkulu zingabalwa. Xa ukhetha ipompo, ukuhamba okuphezulu kuthathwa njengesiseko kwaye ukuhamba okuqhelekileyo kuthathelwa ingqalelo. Xa kungabikho ukuhamba okukhulu, ngokuqhelekileyo amaxesha e-1.1 ukuhamba okuqhelekileyo kungathathwa njengowona mgangatho ophezulu.
   2. Intloko
   Intloko efunwa yinkqubo yokufakela enye idatha ebalulekileyo yokusebenza ekukhethweni kwempompo. Ngokuqhelekileyo, intloko kufuneka yandiswe nge-5% -10% ukukhetha imodeli.
   3. Iipropati zolwelo
   Iipropati zolwelo, kubandakanywa igama eliphakathi kolwelo, iipropati ezibonakalayo, iipropati zeekhemikhali kunye nezinye iipropati, iipropati ezibonakalayo ziquka ubushushu be-c density d, i-viscosity u, i-particle diameter eqinileyo kunye nomxholo wegesi phakathi, njl., ehambelana nentloko yenkqubo, i-cavitation esebenzayo Ukubalwa kobuninzi kunye nohlobo lwempompo olufanelekileyo: iipropati zeekhemikhali, ngokukodwa zibhekiselele kwi-corrosion yekhemikhali kunye ne-toxicity ye-medium medium, eyona siseko esibalulekileyo sokukhetha izinto zempompo kunye nohlobo lwesitywina se-shaft.
   4. Iimeko zokubeka imibhobho
   Iimeko zobeko lwemibhobho yesixokelelwano sesixhobo zibhekisa kumphakamo wonikezelo lolwelo, umgama wokuhanjiswa, isalathiso sonikezelo, idatha ethile efana nenqanaba lolwelo olusezantsi kwicala lokufunxa, inqanaba lolwelo oluphezulu kwicala lokukhupha, kunye neenkcukacha zombhobho kunye ubude babo, imathiriyeli, iinkcukacha zokufakwa kombhobho, ubungakanani, njl.njl. Ukuze kuphunyezwe ubalo lwentloko yekama kunye netshekhi ye-NPSH.
   5. Iimeko zokusebenza
   Kukho iimeko ezininzi zokusebenza, ezifana nokusebenza kolwelo T ohluthisiweyo woxinzelelo lomphunga P, uxinzelelo lwecala lokufunxa PS, ukukhupha uxinzelelo lwesikhongozeli sePZ, ukuphakama, ubushushu be-ambient nokuba umsebenzi uphakathi okanye uyaqhubeka, nokuba indawo yempompo imisiwe okanye inokwenzeka.
