Embodiment Construction
[0018] The structure of the vortex chamber of the spiral water pump is as follows: image 3 As shown: the vortex chamber is divided into three parts: the water outlet channel 1, the water inlet channel 2 and the tongue 4. The center of the vortex chamber is the area where the impeller 3 is installed. Between the contour line of the impeller rotation and the outer wall of the vortex, the impeller is surrounded to form a sequentially connected water inlet channel 2 and water outlet channel 1 in a spiral shape. The outer wall of the water inlet passage 2 of the vortex chamber is composed of 3 to 5 sections of arcs, and the diameter of the arcs gradually increases. At the same time, the dimension height from the bottom surface of the vortex chamber to the installation surface 5 of the pump body gradually deepens, such as Figure 4 Shown: Points M and N are respectively taken on the inlet and outlet channels of the vortex chamber. The cross-sectional heights of the two points are ...
