Title: Ezo Kita: Innovator in Pump Technology
Introduction
Ezo Kita is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of pump technology, holding 2 patents that showcase his innovative approaches to improving pump operations.
Latest Patents
Ezo Kita'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 involves analyzing oscillation components in the output signal from the pressure detecting means. The detection process identifies when the pump's operating point enters a counterflow characteristic operation region based on the spectrum distribution of the detection signal. To escape this region, the method suggests temporally throttling the guide vane and increasing the rotating speed. The second patent elaborates on controlling pump operations similarly, emphasizing the importance of detecting counterflow and managing the pump's performance effectively.
