Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] Figure 4 Figure 5, Figure 32 Figure 33 , Fig. 46 Fig. 47, among the three embodiments shown in the three groups of figures, the mine vertical pump—the light-duty welded sand discharge submersible pump has a pump body 27, a pump shaft 26, an impeller 28 and a motor. Its motor has a casing 21 , an upper end cover 22 , a lower end cover 23 and a stator rotor 24 . The casing 21 together with the upper end cover 22 and the lower end cover 23 forms a closed motor chamber cavity 25 . The motor shaft hole has a mechanical seal 49. In Fig. 6, the pump body has a single single drainage outlet, and there are five partitions 137 in the space between the circular shell of the pump body 27 and the deflector 136 in the shell. In Fig. 7, the pump body has double drain outlets, and there are 10 dividing plates 137 in the space between the circular shell of the pump body 27...
