I. Overview of the device which is suitable for the liquid in the presence of small isolated maximum suspended solids to achieve solid, purpose-liquid two-phase separation. The device is easy to plug the existing similar devices, easy to damage, repair and maintenance workload, investment and other issues of secondary research is one of the best wastewater treatment applicable to practical technology. The device is widely used in solid-liquid separation in need of a variety of occasions. Such as sewage treatment urban sewage, paper making, textile, printing and dyeing, chemical and sewage. Cost of wastewater treatment. Second, the technical characteristics of the name of the processing power t / h with an operating speed of motor kw aerators 10--50 2.2 1450r / min Third, the structure and working principle aerators by the motor, coupling, connecting shaft, mechanical seals, bearings part, the impeller six major components. Aerators and bubbles through the motor speed rotation of the intake air. Then through a stainless steel aeration impellers "microbubbles" are uniformly distributed in the water, so do not be jammed. Fourth, the installation instructions 1, the aircraft factory before passing inspection debugging by adding water after leaving the factory. 2, when you install the motor base must be level deviation shall not exceed ± 0.5mm. 3, before the boot should check whether all lubrication points lubrication reliable, add oil as required. V. Power: 1, first check the unit before turning the bolt is solid, whether the coupling is positive. 2, each section is a good note lubricants. 3, check whether the pool is filled with water. 4, start the motor. 5, when the first boot, running for some time, check for unusual sounds. Sixth, stop 1, stop the motor work. 2, under anhydrous state, the motor does not allow long-term work.
