Abstract
A flexible guide vane structure of a mixed flow pump with adjustable flow area, a mixed flow pump and an adjustment method are provided. The flexible guide vane structure includes a flexible guide vane and a flexible guide vane adjusting device. The flexible guide vane adjusting device includes a support rib, a support rib base and a base driving mechanism. As the skeleton of the flexible guide vane, the support rib realizes the shape change of the flexible vane through the base driving mechanism and the support rib base. In the mixed flow pump, the flexible guide vane adjusting device is installed inside the blade hub. Through the flow section feedback regulation system, the angle of the support rib is adjusted based on the real-time working condition of the mixed flow pump to adjust the flow area of the blade and achieve the best working condition.
