Abstract
An improved blade design and method for enhancing the efficiency of operation of a centrifuge is disclosed based on measuring a varying value of the load on the centrifuge as the flow of contaminated fluid is injected into the centrifuge. The centrifuge has a plurality of blades with radially overlapping edges to keep the fluid being centrifuged compartmentalized and thus quiet for maximum efficiency. Additionally, the scraping blade assembly has blades which are angled in the scraping direction to force the solids towards the exit of the centrifuge, whether that be at the bottom or the top. A programmable logic controller monitors the load on the drive motor and compares a baseline value of load after accelerating the rotor to speed to the value of load while the contaminated fluid is injected into the rotor. The varying second value of load, measured during injection of fluid into the assembly, is compared to the baseline value of load to determine flow rate of the fluid being injected into the rotor assembly or to ascertain whether any dysfunction is occurring and to take appropriate steps to correct malfunction.
