Ukuba ufuna ukwazi yonke into impompo ye turbine enezigaba ezininzi ezithe nkqo , kukwabalulekile ukwazi malunga nolwelo kunye nolwelo oluluthuthayo.

Ulwelo kunye nolwelo

Kukho umahluko obalulekileyo phakathi kolwelo kunye nolwelo. Ulwelo lubhekisa kuyo nayiphi na into ephakathi kwezigaba eziqinileyo kunye nerhasi. Ukuba into ikwimo yolwelo kuxhomekeke kubushushu kunye noxinzelelo olufumanayo, kunye neempawu zangaphakathi zento ngokwayo.

Ulwelo yiyo nayiphi na into ekwazi ukuhamba ngokuqhubekayo kwaye iyakwazi ukwenza nayiphi na imilo yesikhongozeli esikuyo. Nangona oku kuchaza ngokugqibeleleyo ulwelo, kusenokusetyenziswa ukuchaza iigesi. Ngamanye amazwi, lonke ulwelo lulwelo, kodwa ayilulo lonke ulwelo olukwimo yolwelo. Ngoko ke, ngokuqhelekileyo, xa igama elithi "fluid" lisetyenziswe kwi impompo ye turbine enezigaba ezininzi ezithe nkqo, ibhekisela kulwelo, njengoko iimpompo zingenzelwanga ukuthutha iigesi.

Ulwelo luneempawu ezibonakalayo eziphambili ekufuneka ziqwalaselwe kwizicelo zokumpompa, ezizezi, i-viscosity, ingxinano, kunye noxinzelelo lomphunga (uxinzelelo lwe-vaporization). Ezi mpawu zibalulekile ekuqondeni indlela ulwelo oluziphatha ngayo kwaye yeyiphi impompo eyifanele kakhulu.

I-Viscosity ibhekisela ekuxhathiseni ulwelo ukuba luhambe, okanye indlela "incangathi" ngayo ulwelo. Oku kuya kuchaphazela umyinge wokuhamba, intloko iyonke, ukusebenza kakuhle, kunye namandla empompo ye-injini yomoya ethe nkqo.

Uxinaniso lubhekisa kubunzima bento equlethwe kumthamo othile. Ekumpompeni, ikwabizwa ngokuba kukuxinana okuzalanayo (umxhuzulane okhethekileyo), nto leyo engumlinganiselo woxinaniso lwento kubuninzi bamanzi kwiqondo lobushushu elithile. Ukuxinana kunye nomxhuzulane okhethekileyo uyafuneka ukuze kubonwe amandla afunekayo ukuhambisa ulwelo olunye ukuya kolunye.

Uxinzelelo lomphunga luxinzelelo apho ulwelo luqala ukujika lube ngumphunga (umphunga), kwaye kubalulekile ukujonga oku kwinkqubo yempompo. Ukuba uxinzelelo kwimpompo luphantsi kunoxinzelelo lwe-vaporization yolwelo, i-cavitation ingenzeka.

Ukuqonda umahluko phakathi kolwelo kunye nolwelo kunye nendlela ulwelo oluziphatha ngayo kubalulekile kumsebenzi wempompo yeinjini yeijinithi ethe nkqo yezigaba ezininzi.
