Abstract: A control system for a centrifuge that allows the centrifuge to continue to run when there is a short duration failure or outage of the AC power source. The control system allows the centrifuge to be brought to a stop in a normal shutdown mode where there are longer duration failures or outages of the AC power source. This allows power to be maintained to the pump that lubricates the centrifuge bearings so that the bearings are lubricated during the coast down of the centrifuge and the differential speed of the centrifuge to be controlled during coast down allowing the centrifuge bowl to be cleared of solids so that the centrifuge can be immediately started up at lower vibration levels once power is restored.
Abstract translation: 用于离心机的控制系统,允许离心机在短时间故障或AC电源中断时继续运行。 控制系统允许离心机在正常关机模式下停止,在正常关机模式下,持续时间较长或交流电源中断。 这样可以维持泵的润滑功能,从而润滑离心机轴承,使轴承在离心机的滑落过程中被润滑,离心机在滑行过程中的差速速度允许离心机碗清除固体。 一旦电源恢复,离心机可以立即以较低的振动水平启动。
