Abstract

Njengesixhobo sokuthutha ulwelo olusebenza kakhulu olusetyenziswa ngokubanzi kwiiprojekthi zogcino lwamanzi, ishishini lepetrochemical, kunye neenkqubo zobonelelo lwamanzi ezidolophini, iimpompo zeinjini zomoya ezithe nkqo zithatha i-30% -50% yosetyenziso lwamandla lulonke lwenkqubo. Iindlela zesiqhelo zokulawula isantya esizinzileyo zithwaxwa yinkcitho yamandla ngenxa yokungakwazi kwazo ukuhambelana neemfuno zokuqukuqela. Ngokuvuthwa kobuchwephesha be-variable frequency control (VFS), ukusetyenziswa kwayo kugcino lwamandlaiimpompo ze turbine ezithe nkqoiye yaba yeyona ndawo iphambili kushishino. Eli phepha liphonononga ixabiso eliphambili leenkqubo zeVFS ukusuka kwimigaqo yobugcisa, iziphumo ezisebenzayo zokonga amandla, kunye neembono zoqoqosho.

1.1 IMithetho-siseko eSisiseko yoLawulo lwezaNtyaniso eziGuquguqukayo

Iisistim ze-VFS zihlengahlengisa unikezelo lwamandla ombane (0.5–400 Hz) ukulawula isantya sempompo (N∝f), ngokwenjenjalo kulawulwa izinga lokuhamba (Q∝N³) kunye nentloko (H∝N²). Abalawuli abangundoqo (umzekelo, ii-VFDs) basebenzisa ii-algorithms ze-PID zolawulo oluchanekileyo lokuhamba-noxinzelelo ngohlengahlengiso oluguqukayo.

1.2 Iimpawu zokuSebenza zeeMpompo zeTurbine eziNqobileyo ezininzi kunye noKuguquguquka kwazo kwiVFS

Ezona mpawuiquka:
