Latest Patents

Yokoyama's latest patents include a method of counterflow through a pump and a method of controlling the operation of a pump in a pumping installation. The first patent describes a method for detecting counterflow in a pump by utilizing detecting means to monitor variations in discharge pressure. It also involves signal analyzing means to assess oscillation components in the output signal from the pressure detecting means. The invention allows for the detection of the pump's operating point entering a counterflow characteristic operation region based on the spectrum distribution of the detection signal. When this occurs, the method enables the pump to escape from that region by temporarily throttling the guide vane and increasing the rotating speed. The second patent elaborates on similar principles, focusing on the control of pump operations to enhance efficiency and reliability.
