DQ-type self-priming magnetic drive centrifugal pump (referred to as self-priming magnetic pump) is the permanent magnet coupling working principle applied to self-priming centrifugal pumps, external mixing axial pump structure, the pump from the suction chamber, storage Liquid chamber, volute, backflow hole, gas-liquid separation chamber and other components. The magnetic pump has the advantages of compact structure, beautiful appearance, small volume, low noise, reliable operation, and reliable operation. The utility model has the advantages of complete sealing, no leakage and corrosion resistance, and the performance of the self-priming magnetic pump reaches the advanced level of the foreign similar products. Can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film and photographic printing, scientific research institutions, national defense and other units pumping acid, lye, oil, precious precious liquid, bath, volatile liquid, Water equipment package. Especially flammable, explosive, volatile liquid pumping, self-priming magnetic pump works is the pump starts, under the action of centrifugal force, the remaining liquid in the suction chamber and the inlet pipe air The mixture is stirred into an air-water mixture by the impeller, and the mixture enters the gas-liquid separation chamber through the volute. As the speed slows down, gas and water are separated, the air is discharged from the pump liquid outlet, and the liquid is returned to the pump through the water return hole. , Into the liquid pipe is drained of air, so that the pump to form a certain degree of vacuum to achieve the role of self-priming.
