ZCQ self-priming magnetic drive pump (hereinafter referred to as self-priming pump), the pump to replace the static seal dynamic seal, the pump over-current components in a completely sealed state, completely solve the other pump mechanical seal can not be run, run, Drip, leakage of defects, ZCQ-type self-priming magnetic pump body and flow components are made of corrosion-resistant stainless steel, steel jade ceramics, PTFE graphite and other materials, both CQ-type magnetic drive pump function, Also set soap sucked in one, without the end of the valve and lead irrigation water, self-priming height of 4 meters. ZCQ self-priming magnetic pump works: The use of external mixed axial backwater pump body structure, the pump from the suction chamber, liquid storage chamber, volute, return hole, gas-liquid separation chamber and other components, the structure shown in the figure. After the pump is started, under the action of centrifugal force, the remaining liquid in the water absorption chamber and the air in the liquid inlet pipe are 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, Water is separated, the air is discharged from the pump liquid outlet, and the liquid is returned to the pump through the water return hole. After several cycles, the air in the liquid inlet pipe is drained out to make a certain degree of vacuum in the pump to achieve the self-priming effect. ZCQ type self-priming magnetic pump features: The pump structure is compact, beautiful appearance, small size, low noise, reliable operation, easy maintenance, magnetic pumps are widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research, etc. Unit pumping acid, alkali, oil and rare precious liquid, venom, volatile liquid, and water equipment supporting circulation, especially easy to leak, flammable, explosive liquid pumping.
