First, the working principle LFPQ-B type fronds aeration agitation applied a number of dual-use principles of fluid mechanics. When the spindle to rotate with the spindle rotation in the complex impeller impeller region is formed around a strong negative pressure area, so that the air drawn into the turbulence chamber, air is sucked in high-speed rotation liquid strong shearing, grinding, emulsifying, bubble diameter decreases rapidly, prompting rapid oxygen molecules from the gas phase, sufficiently diffused into the liquid phase to achieve the optimum moisture synthesis. Carry both water and oxygen molecules in fine bubbles under the water, driven by the diversion orientation distribution, at an angle to the bottom 360 along the fast? Diffusion jet direction, and drive the sludge slowly turning rise further in the process of oxygen fully dissolved. Water and gas throughout the aeration tank to form a large loop flip up and down, and the promotion of bottom sludge and turning often in a suspended state, increasing the contact surface phase, wiped out entire aeration tank aeration dead, reach uniform aeration purposes, processing efficiency is improved. LFPQ-B type fronds aeration agitation is based on dual-use type fronds LFPQ-A plug-flow aerators on underwater to improve the design of the impeller, it at different speeds along with the deep-water suction intake and large displacement linear propulsion two properties. In practical applications, the speed is changed by the control system and the exchange of time, you can automatically stir deep water aeration and circulation of two independent working condition, one machine, especially for OAO, MSBR other technology. LFPQ-BII fronds enhanced aeration type mixer is based on the full market research, comprehensive use of propeller technology, centrifuge technology, gas and water jet technology and hybrid technology and one of the best aeration mixing equipment. Underwater motor cooling effect, the shaft is short, improve equipment efficiency, low failure rate, long life, easy installation and maintenance. LFPQ-BII type enhanced aeration agitation fronds dual-purpose machine by adjusting the motor speed to push flow aeration or mixing function alone, with one machine role needs to be applied to the gap and the need for aeration stirring occasion, in Under stirring power consumption is only one-third of the aeration time. Second, product characteristics 1. High oxygenation efficiency, power efficiency up 1.6-2.72kgO2 / kw.h depending on the power. 2. To achieve deep water aeration, secondary oxygen, small bubble size, surface area, gas, liquid mud mixed, dissolved oxygen sufficient, good effect. 3. Using a large circulating water flow scheme of the machine only has the aeration function, but with a stirring function, and full of sludge stir for 1-8 meters water depth, the radiation area of ??1-600 meters. 4. aerator power for submersible motors, dive underwater work when the application is not only good cooling conditions, wide depth range, and no secondary pollution, noise coaxial motor and aerator, to reduce unnecessary mechanical loss and improve the efficiency of the unit. 5. Dry submersible motor main seal for two tandem mechanical seals, while also using a multi-channel auxiliary sealing system to ensure the reliability of the motor seal; wet submersible motor mechanically, while also using a multi-channel auxiliary sealing system bearings with water-lubricated bearings, motors are filled with water type, working pressure can be adjusted depending on the motor cavity diving depth motor, the motor can ensure the efficient and safe operation under different working depth. 6. dry motor may be leaking, the stator overtemperature, phase, short circuit protection and a number of alarm systems to make our products more secure and reliable; though to be wet motor phase, short circuit protection alarm systems, open space must be leaking protection switch. 7. Using Outdoor overall structure and withdrawable unit, without the construction of a dedicated plant and build a mounting platform (floating installation), integrated investment province; machine mounted on floats, floats can be changed as needed fixation, bridge type, bottom weight fixed, easy installation and maintenance. 8. shaped pool is not limited in size, can be configured according to the oxygen demand model, a machine Koike a pool, large pool can be a pool of multi-machine.
