First, use: QSB4.0 stainless steel 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. Second, the principle: 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, the airway by inhalation of air, the air entering the mix After the gas 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 mass transfer is formed in the whole process. Third, the performance characteristics: 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, QSB4.0 stainless steel jet aerator conditions apply: QSB4. 0 stainless steel jet aerator can be normal continuous operation 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 five, QSB4.0 stainless steel jet aerator performance parameters 1, power kw ---- 4.0 2, current A ----- 4 3, voltage ------- 380 4 speed r / min ----- 2900 5 frequency Hz ------- 50 6, insulation class ------ F 7, maximum immersion depth m ------- 4 8, intake air m3 / h ----- --509, intake manifold port mm ------- 50 six, selection and installation: it takes the company to assist selection, the user should provide pool type, media properties, the required amount of intake air, diving depth, etc. relevant data, to enable the company to design and provide high-quality equipment, to better meet the needs of users. Installation form QSB4.0 stainless steel 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.
