Shijiazhuang-school Pump Co., Ltd. ZX self-priming pump on the other hand, gas and water discharged by the impeller in the water separation chamber and flows back through the impeller backwater hole around the outer edge. Backwater hole left in the water flows back under the action of the pressure difference and gravity 150ZX170-65 pump, directed channel impeller, and impeller shattered, and after suction line to the air mixing pump, rejection 150ZX160-80 to volute pump, flows in the direction of rotation. The self-priming pump impeller height with the peripheral speed u2 increases, but the maximum self-priming height, speed increasing and self-priming height will not increase the 200ZX280-63 pump, this time just shortened from Suction time; when the number of revolutions of decline, along with the decline in self-priming height. In other conditions remain unchanged, self-priming height also increases storage height increases (but not exceed the height of the separation chamber optimum storage). 200ZX280-63 priming pump | Shijiazhuang (certified) | by Shijiazhuang-priming pump Pump Co., Ltd. faction.
