What are the characteristics of self-priming pumps?

The self-priming pump is a general-purpose mechanical product consisting of a motor, a pump shaft, a pump casing, an impeller, a water inlet, and a water outlet. The utility model realizes: consisting of a pulley, a pump shaft , a water blade, an inner flow plate, a jet pipe, a pump body, a water inlet and a water outlet. Large flow, high lift, self-priming pump, impeller, inlet and outlet.

It is characterized in that the water leaf is symmetrically arranged by the spiral type blade with six stages, and each group has two pieces, one long and one short, and a flow path is formed between the blades to ensure the hydraulic performance of the pump . The spout is provided with a side inlet and a pressurized inlet. The side water inlet on the side of the jet pipe communicates with the water inlet of the pump body, and the baffle on the other side is provided to ensure that the water exits through the water outlet after the water enters the flow plate and water through the side water inlet when the pump is working. The upper part is composed of two parts, the upper part is provided with an annular protrusion, and the lower part is open on both sides, which is called a side water inlet and a bottom opening.
