Embodiment Construction
[0017] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0018] figure 1 The shown constant pressure vortex pump includes a pump body 1 , a seal ring 2 , an impeller 3 , a mechanical seal 4 , a pump cover 5 , a bracket 6 and a motor 7 . The suction end of the pump body 1 is provided with a seal ring 3 matching with the inlet of the impeller 3, and the pump cover 5 with the built-in mechanical seal 4 is coaxially sealed with the pump body 1, and the pump cover 5 is connected with the motor 7 through the bracket 6 as a whole. The output shaft end of the motor 7 axially passes through the mechanical seal 4 , and the protruding shaft end is used for installing the impeller 3 . The impeller 3 is as figure 2 , image 3 and Figure 4 As shown, it is a disc-shaped member with a diameter of D2 and a semi-open structure. The impeller 3 in this embodiment is mainly composed of 10 main blades 3.3 un...
