One, QSB3.0 deepwater jet aerator uses: QSB3.0 deepwater jet aerator is suitable for sewage treatment plant aeration tank, grit tank, the mixture of sewage sludge on oxygenation and mixing and biological treatment of sewage or aquaculture ponds oxygen. Two, QSB3.0 deepwater jet aerator works: In the high-speed rotation of the pump impeller, the liquid at high speed from the nozzle, high-speed flow of liquid through the mixing chamber, it will create a vacuum in the mixing chamber, by airway inhalation of air, after the air into the mixing chamber, at the throat so vigorously mixed with a liquid to form a gas-liquid mixture, is discharged from the diffuser, fine air bubbles in the water to rise, efficient material formed over the entire process delivery. Three, QSB3.0 deepwater jet aerator Features: 1, compact structure, small footprint easy installation. According to the characteristics of the aeration tank, the size and volume of sewage treated sewage into the pool layout flexibility to choose indicators, diving depth, such as the use of several units. 2, high efficiency aeration wide range of applications. Because of its high-speed jet flow pattern, liquid gas mixture sufficient oxygen absorption rate, high power efficiency. High efficiency than conventional aeration tank 3 to 4 times, aeration time can be significantly reduced, and for a variety of wastewater treatment, including the plug-flow aeration tank, aeration tank mix, extended aeration tank, oxidation ditch, oxidation ponds. 3, the system is simple, high reliability. Without blowers and other equipment, the system is simple, in addition to inhale the estuary, the rest of the dive operation, low noise, safe and reliable equipment. 4, low investment and operating costs. Because jet aerator is suitable for deep aeration tank, reducing the footprint, the system is simple, saving investment costs, high processing performance, operating cost savings four, QSB3.0 deepwater jet aerator conditions apply: QSB3 .0 deepwater jet aerator can normally run continuously under the following conditions: a maximum medium temperature does not exceed 40 ° C; 2 PH value of the medium at 5-9; 3 medium density does not exceed 1150kg / m 3. Fifth, the model representation: QSB - submersible jet aerator 3.0 - motor power kW six, QSB3.0 deepwater jet aerator performance parameters 1, power kw ---- 3 2, current A ----- 6.4 3, the voltage ------- 380 4 speed r / min ----- 2900 5, the frequency Hz ------- 50 6, insulation class ------ F 7, The maximum immersion depth m ------- 4 8, intake air m3 / h ------- 50 9, the intake manifold inlet mm ------- 50 Note: The table and into the gas aerobic capacity under standard test conditions (20 ° C water temperature, pressure 101.325kPa), aerators diving depth 3m, test medium is water. In moderate sewage, gas capacity can be increased as the design basis coefficient 0.85. Seven, selection and installation: it takes the company to assist selection, the user should provide pool type, data media properties, the required amount of intake air, diving depth, so the company designs and delivers high-quality equipment to better meet user demand. Installation form QSB3.0 deepwater jet aerator has auto and mobile two. Auto-mount is the aerator and a dedicated base is fixed at the bottom of the pool, ancillary support block installed in the top of the pool, so that the two are connected by rail, submersible pump bracket coupled with a specific decline in the end after a good seat along the rail exports position, by a pump own weight, automatically coupled and sealed. Auto-installation without installing or maintenance personnel to enter the sump pump to lift and install. Mobile installation is self deepwater submersible jet aerator installed in the bottom of the pool, its own weight positioning, with the installation location can be varied, flexible, and low cost. Eight, Note 1, when the absolute prohibition of direct lifting equipment lifting cable or other cable lifting heavy objects. In carrying or hanging diving aerators available hooked chain shackle or hook on the cover of the rings. 2, the cable end is prohibited immersed in water. 3. Housing All equipment should be grounded to prevent electric shock. 4, due to the working principle, the maximum immersion depth should not exceed the specified value. 5, sewage submersible aerator can not be placed at the entrance, when the chassis on mud or quicksand, submersible aerator subsidence due to vibration generated, in this case, it is recommended to mount up or put aerators a larger bottom plate. 6, when the temperature drops below 0 ℃, if the submersible aerator is still functioning can continue to use, or should be lifted in a ventilated and dry place, and pay attention to antifreeze.
