Industrial submersible aerator QXB2.2

Submersible aerator selection of Nanjing blue river Treatment Equipment Co. specializes in manufacturing QXB centrifugal submersible aerators, various aerators Guinness, please contact use:! QXB centrifugal submersible aerators for wastewater treatment plant aeration tanks, aerated grit chamber, to a mixture of sewage sludge oxygenation and mixing, and biological treatment of sewage or aquaculture ponds oxygen. Principle: QXB centrifugal submersible aerators for direct coupling structure. Rotating impeller produces a centrifugal force in the water, by the centrifugal force in a zone of negative pressure is formed around the impeller, the air is sucked through the intake pipe and is sucked into the air and water are mixed in the mixing tray, which then automatically good uniform mixture from the discharge export ejected four weeks. This process includes the following aspects: Mixed intraday air is mixed with water to produce a gas-liquid mixing effect, outlet gas-liquid mixture form a cycle and convection; a large number of molecular oxygen in the air to get a high-speed movement of oxygen absorption efficiency . Features: a high oxygen dissolution rate, the percentage of tiny bubbles, high efficiency and oxygenation oxygenation wide area; two pools no dead zone, the level of aeration bubbles entrained flow completely scour every corner of the bottom of the ; 3 structure is simple, compact, long unit life, can withstand heavy load bearing, shaft seal with oil bath air impeller and suction chamber to prevent contact with water and seal work, these are guaranteed aerators in 24 hours of continuous work Long-term trouble-free operation; 4 save project investment, without providing gas source, eliminating the need for fans, easy installation, low noise; Schematic: QXB centrifugal aerator three main technical parameters, QXB centrifugal aerator Caution 1, Never allow cable aerators with lifting or suspension aerators. In carrying or hanging aerators are available with fishing hook on a chain handle or lid on the rings. 2, the fruit is still in use aerators or immersed in water, when the temperature below 0 ° C, you can continue to use. 3, aerators use grease or oil, since the seal wear, grease or oil will leak. Time. Please hurry the aerator to the maintenance department of the company or delegate maintenance, replacement sealed to prevent motor burnout. 4, the end cut off the power, not moving aerator, who shall enter the water. 5, after the installation of submersible aerator, not long-term immersion in water and do not recommend running at least every four hours and a half to check its functionality and adaptability, or bring in a dry place for use. 6, sewage submersible aerator can not be placed outside the entrance. When the chassis on mud or quicksand, submersible aerator subsidence due to vibration generated, in this case, we recommend that the aerators mount up or placed on a larger negatives. 7, diving aerator is necessary to ensure safety. QXB centrifugal aerator maintenance instructions for each factory, are carefully carried out the final inspection to ensure product reliability using submersible aerator. In order to ensure the life of the boldness of the machine, we recommend regular inspection and maintenance. 1, cleaning in order to prevent diving aeration plot within different periods of impurities, can dive aerator pump clean water to clean the diving aerator. Submersible aerators unused for long periods, should be placed in a dry place, and pay attention to antifreeze. 2, grease and oil change oil chamber submersible aerators at the factory, has been injected into the right amount of oil. The oil should be replaced annually. Oil change according to the following method: Place the submersible aerator good, so that the oil chamber plug down, loosen the plug, release oil, then washed with oil washing oil chamber, and then inject the right amount of lubricant, for a New Ο-ring, tighten the plug. If the oil is found in the water, according to the provisions of flushing oil chamber and re-filled with oil, tighten the plug tight with O-rings. Must be checked once again, if the oil has become an emulsion, respond mechanical seals to be checked after three weeks. Replace if necessary (please contact with our maintenance department). Note: The oil for transformer oil. 3, in case of operational failure faulty operation, if not determine the cause, according to the troubleshooting methods given later still unresolved, not using makeshift methods, and do not mess repair indiscriminate demolition without permission.
