Latest Patents

Okada holds a patent for a "Method of starting operation for a pump or a pump turbine." This invention addresses the challenges faced during the starting operation of high head and large capacity pumps. The method involves fully closing adjustable guide vanes and introducing compressed air within the runner casing to depress water around the runner. As the runner begins to rotate at synchronous speed, the guide vanes are excessively opened to prevent reverse flow. Once the discharge flow stabilizes, the guide vanes are adjusted to a predetermined position to achieve maximum flow rate with minimal noise and vibration.
