WPLL Series Cov Ntsuas Dej Turbine Ntws Uas Txawj Ntse
WPLL Series lub ntsuas dej ntws ntse siv dav los ntsuas cov kua dej ntws tam sim ntawd thiab tag nrho cov kua, yog li nws tuaj yeem tswj thiab ntsuas qhov ntim kua. Lub ntsuas dej ntws turbine muaj lub rotor ntau-bladed mounted nrog lub yeeb nkab, perpendicular rau cov kua ntws. Lub rotor tig thaum cov kua hla dhau cov hniav. Qhov ceev tig yog ib qho kev ua haujlwm ncaj qha ntawm cov dej ntws thiab tuaj yeem hnov los ntawm kev khaws hlau nplaum, photoelectric cell, lossis iav. Cov hluav taws xob pulses tuaj yeem suav thiab tag nrho.
Cov coefficients ntawm lub ntsuas dej ntws uas muab los ntawm daim ntawv pov thawj calibration haum rau cov kua no, uas viscosity tsawg dua 5х10-6m2/s. Yog tias cov kua viscosity > 5х10-6m2/s, thov rov kho qhov sensor raws li cov kua tiag tiag thiab hloov kho cov coefficients ntawm cov cuab yeej ua ntej pib ua haujlwm.
