Flow line design method of molten salt pump impeller
The dividing line is an important step of designing molten salt pump impeller hydraulic. So the dividing line is that a section is divided into several equal peccadillo water section. It is generally divided into three line for low specific speed and specific speed impeller. The low specific speed and specific speed impeller refer to the middle streamline and front and back cover of the streamline. It is divided into five line for high specific speed impeller. It refers to that it needs to do three line in addition to the two line at the cover plates.
First of all, we must first distinguish the difference between middle streamline and channel midline, the two are different. The channel midline is the geometric midline of the channel and it is the line of the inscribed circle’s center. and the flow of the two channel is equal that it consists of any three adjacent line. because the velocity for the every parts of the entire flow is not uniform, so middle streamline is not coincident with the channel midline.
