Iinkqubo ezininzi kwishishini kufuneka zithuthe ulwelo ukusuka kwenye indawo ukuya kwenye, zidlala indima ebalulekileyo.Iquka uluhlu olubanzi lwamashishini, ukusuka kwimizi-mveliso emikhulu yamandla enyukliya kunye neendawo zombane eziqhelekileyo, imibhobho ye-oyile, amaziko epetrochemical, amaziko kamasipala okucocwa kwamanzi amdaka kunye nezityalo zamanzi, ukuya kwizakhiwo ezikhulu nezincinci, iinqanawa namaqonga e-oyile aphesheya konxweme.Ngokuqhelekileyo, impompo luhlobo lwezixhobo eziqinileyo nezithembekileyo kumatshini ojikelezayo.Nangona kunjalo, kwiinkqubo ezininzi, ipompo sisixhobo esiphambili.Emva kokuba isilele kwaye ihla, imiphumo idla ngokuba yingozi okanye ibe yintlekele.Ukongeza kwilahleko yezoqoqosho ngokuthe ngqo, iingxaki zokhuseleko akufanele zijongelwe phantsi okanye zide zigqithise ilahleko yezoqoqosho.Umzekelo, ukuvuza kwezinto ezine-radioactive okanye ulwelo oluyityhefu olubangelwa kukungaphumeleli kwempompo kuya kuchaphazela ubomi babasebenzi abafanelekileyo besityalo, nkqu nabantu abasingqongileyo.Ukongeza, izinto zokukhuselwa kwendalo ziyafana.Ukusilela kolwelo oluyingozi ngenxa yokuvuza kwempompo kuya kungcolisa umoya, amanzi nomhlaba, kwaye kukhokelela kumonakalo ongenakulungiseka kokusingqongileyo.Unyango ludla ixesha, lusebenza nzima kwaye luyabiza.Ngoko ke, nangona ipompo ayisoloko ihlelwa njengeyunithi ephambili, ayininzi kakhulu ukuyiqwalasela njengeyunithi ephambili.

Ukuba uxinzelelo kwimpompo lungaphantsi koxinzelelo lwe-vaporization yolwelo (ucinga ukuba utshintsho oluncinci lobushushu), okanye

Xa iqondo lokushisa le-fluid likhuphuka kwiqondo lokushisa le-vaporization, i-cavitation ingenzeka, kwaye ininzi ye-steam

Isizathu sesokuqala.Kulwelo olunoxinano oluphezulu, olufana namanzi, umonakalo obangelwe kukugqabhuka kweqamza uphezulu kunolwelo olunoxinano oluphantsi, olufana neehydrocarbons.Ukongeza, i-cavitation yenzeka kulwelo olunomthamo omkhulu womphunga wolwelo

Umonakalo mkhulu.

Umonakalo we-cavitation uhambelana nezinto eziphathekayo, ukuyila kunye nokusebenza kwimeko ye-impeller.Ngokuqinisekileyo, ihambelana ngokuthe ngqo kwinani le-cavitation.Iziphumo ziboniswa kule miba ilandelayo:

Intloko yoxinzelelo lwempompo iyancipha nge-3%, enokuthi ithathelwe ingqalelo njenge-cavitation, kodwa ayithethi ukuba ipompo kufuneka yonakaliswe.

Ingxolo - ingxolo eqhumayo, kodwa ayithethi kakhulu.

I-Vibration - kwi-wide frequency range, i-vibration amplitude inkulu, kwaye isiseko sesandi se-spectrum siyanda.Ngokubonakalayo - i-corrosion ibonakala kwicala eliphantsi loxinzelelo lwe-blade, enokuthi ibe yinto ye-cavitation.Impembelelo yefrikhwensi ephezulu kunye ne-corrosion ephezulu yobushushu ibangela imingxuma kwi-blade surface, enokuthi ibe ne-spongy kwaye yonakaliswe ngokukhawuleza kwiimeko ezinzulu.
