Embodiment Construction
[0013] like figure 1 (A, B), figure 2 , image 3 and Figure 4 Shown:
[0014] The flow measuring device is composed of flow measuring vanes 3 , hub 2 and seat ring 1 . The hub 2 is located at the center of the seat ring 1, and four flow-measuring blades 3 arranged vertically and symmetrically connect the seat ring 1 and the hub 2, as shown in figure 1 As shown in (A), it is installed in front of the water pump impeller 6 inlet as a whole through the outer seat ring 1 (in figure 2 , image 3 In the shown vertical unit, the flow measuring device is located at the lower part of the impeller 6); according to the principle of equal flow, the water flow section where the flow measuring device is located is divided into 3 to 5 adjacent flow rings, in this example, 4 phase flow rings Adjacent flow rings; each flow ring has a cross-section surface with the water-facing front of the flow-measuring blade 3, and the center of the cross-section surface is facing the direction of t...
