Verticle opening axial pump

The utility model relates to a vertical open type axial flow pump, which is a novel pump with the two-way running mode of pump drainage and pump drawing. The utility model belongs to the field of the mechanical technology. A water outlet diffusion tube is mainly installed on a guide blade body. A water outlet flow guiding body is installed on the concrete base bottom of a water outlet flow passage. The utility model has the advantages of simple structure, reliable performance, convenient installation, and convenient inspection and repair. Proper two-way water inlet flow passage, a water outlet flow passage and a gate are matched with the original pump shaft. The rotation direction of a pump is not changed. The switching over of the forward and reverse direction of the water flow can be conveniently realized through the control of the gate on the water inlet flow passage and the water outlet flow passage. The forward and reverse running properties are consistent.
