Self priming pump self-priming performance is how to achieve?
Self priming centrifugal pump working principle is: the water pump start before the pump shell filled with water (or pump shell has its own water). After the start of the high-speed rotation of the impeller the impeller in the water trough road to the vortex shell, then the entrance to form a vacuum, to open the door check water, inhalation of air into the tube pump, and the impeller channel to reach the outer edge. On the other hand, was routed to gas water separation chamber impeller in the water then flows back by about backwater hole of the outer edge of the impeller. Backwater hole left back at the water pressure difference and gravity, fired channel impeller, the impeller was shattered, and inhalation of air pipes to a mixture, thrown to the volute, flow to the direction of rotation. Centrifugal force is actually the high-speed rotating impeller, water and air in the high speed rotation, centrifugal force generated by the.
