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...

Abstract

The invention is a mine vertical pump being as light welded sand-discharging submersible pump. In the invention there are several diaphragms in the space between the pump casing and the fluid-guiding plate. In the space divided by the diaphragms there is a channel grid with the channel opening on the casing end cover plate and a stifling grid enclosed by the casing end cover plate.

Description

technical field [0001] The invention relates to a mine vertical pump, a light-duty welding submersible sand discharge pump, which is an amphibious water pump for both land and underwater use, and is suitable for transporting impurity submersible pumps or sand discharge submersible pumps containing solid abrasive particles in liquid. Background technique [0002] At present, a low-specific-revolution multi-stage sand-discharging submersible pump with a small flow rate and a high head has not yet been retrieved. The technical difficulty of this multi-stage sand discharge submersible pump is that if it is modified with a single-stage slurry pump, the structure will be complicated, the axial force balance will be difficult, and the axial leakage will be difficult to control. In addition, the whole machine is huge and inconvenient to use, so there is no ideal model so far. Contents of the invention [0003] The purpose of the present invention is to provide a land and underwat...
