14、 Self suction pump single-stage single suction

The working principle of a self-priming pump is to fill the pump casing with water (or the pump casing itself with water) before starting the pump. After starting, the high-speed rotation of the impeller causes the water flow in the impeller channel to flow towards the vortex shell. At this time, a vacuum is formed at the inlet, causing the inlet check valve to open, and the air in the suction pipe to enter the pump and reach the outer edge through the impeller channel.

Performance characteristics:

Self priming pumps belong to self-priming centrifugal pumps, which have the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Different liquids can use self-priming pumps made of different materials.

1. Strong sewage discharge capacity: The special impeller anti blocking design ensures that the pump is efficient and unobstructed. 2. Efficient and energy-saving: Adopting excellent hydraulic models, the efficiency is 3-5% higher than that of general self-priming pumps. 3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter.
