First, the principle and purpose: the water produced by the submersible pump high-speed flow through the nozzle formed in the nozzle around a negative pressure of the intake air, the water flowing through the mixing chamber and the mixing of water generated by the formation of high-speed submersible pump water through the nozzle, the nozzle is formed around the negative intake air pressure, by mixing the mixing chamber with water ,, produce water vapor mixing flow in the diffuser tube flared, high-speed jet out many bubbles entrained flow vortex stirring in a larger area and depth of the waters, complete aeration , and the shaft power does not change with diving depth varies, intake air can be adjusted. Because of this, the jet aerator can vary widely applied in water level in the pool. Second, the submersible aerator Features: The submersible aerator by a submersible pump and a jet pump composition, so that the water agitation and oxygenation at the same time, can get a higher oxygen absorption rate, but also has the advantages of non-clogging impeller. Strong one-way flow, resulting in an effective convection cycle, and the motor load varies with the water level is small, easy to install. Third, the submersible aerators applicable conditions: QSB deep-water can lower self-priming submersible jet aerator in normal continuous operation under the following conditions: 1 maximum medium temperature does not exceed 40 ° C; 2 PH value of the medium at 5-9 ; 3 medium density does not exceed 1150kg / m3. Fourth, the submersible aerator selection and installation: it takes the company to assist the election diving aerators, users should provide POND, data media properties, the required amount of intake air, diving depth, etc., to enable the company to design and deliver high-quality equipment to better meet the needs of users. QSB deep-water installation in the form of self aspirating submersible jet aerator has auto and mobile two. Auto-mount is the aeration device and a dedicated base is fixed at the bottom of the pool, install a support block supporting the pool roof, so that the two are connected by rail, submersible pump bracket coupled with specific decline in the end after a good seat along the rail exports position, by a pump weight, the automatic coupling and sealing. Auto-installation without installing or maintenance personnel to enter the puddles to upgrade and install pumps. Mobile installation is deepwater submersible self-priming jet aerator is attached to the bottom of the pool, its own weight positioning, a mounting position may change, flexible, and low cost.
