Submersible aerator selection of Nanjing blue river Treatment Equipment Co. specializes in manufacturing QXB centrifugal submersible aerators, various aerators Guinness, please contact us! First, use QXB-diving gas explosion machine used for a variety of sewage treatment in Biochemical Engineering Process aeration tank, aerated grit chamber, pre-aeration tank, aeration aerobic nitrification tank mixing and aeration pond aquaculture. Second, the principle QXB-diving gas explosion machine using direct drive motor and impeller, the use of centrifugal force generated by the rotating impeller displaces water to form a low-pressure area around the same time the suction flow, while creating a vacuum in the intake air impeller inlet gas in the gas mixing chamber sufficiently mixed with water to form a homogeneous mixture of air and water, the rapid discharge of the centrifugal force. Due to strong water jets, resulting in efficient water circulation, the air is cut into a large number of tiny bubbles. Greatly increasing its surface area, and because the bubbles rise slowly in the air a lot of oxygen dissolved in the water, making the machine more efficient than other types of power aerator. Third, the characteristics of a unique mixing chamber design, the intake air quantity, good mixing effect, oxygen utilization is high; 2, a special mixture of gas and water discharged from the mixing chamber angle, and make the water flow into a spiral to in the horizontal direction and then flows upward, both in the aeration while stirring; 3, the body sink running water, no noise. Out of the water inlet pipe can be installed muffler, enhancing silencing effect. Fourth, the structural characteristics 1, with the introduction of the Swedish Flygt submersible motor sealing technology underwater motor; 2, impeller and motor directly connected, simple structure, high efficiency, long life; 3, can be added to the mesh intake, avoid foreign body into the body cause unnecessary damage; 4, through the intake valve adjust the feed rate; 5, in addition to the motor, the other parts are made of stainless steel, carbon steel and cast iron available.
