qjb latest offer submersible mixer Scope: Mixers under the following conditions shall be able to continuously run: 1, the maximum medium temperature does not exceed 40 ° C; 2, PH value of the medium in the 5 to 9; 3, liquid density does not exceed 1150kg / m3; 4, long-running diving, diving depth of not more than 20m. Focus Note: diving fully submersible mixer necessary work; do not work in the environment flammable or corrosive liquids; steel bolts shall require fixed, after installation, you must tighten the cable fixed diving. When push current selection, blade diameter of more than 2M, recommend the use of a gearbox reducer qjb submersible mixer latest offer Features: 1, compact structure, operation and maintenance is simple, easy installation and maintenance, long life; 2, the impeller has the most. good hydraulic design structure, high working efficiency, swept-back blade with a self-cleaning function, can prevent wound debris clogging; 3, mixing with aeration system can significantly reduce energy consumption, improve oxygenation was significantly effective prevent precipitation; 4, motor winding insulation class F, protection class IP68, high quality bearings and motor anti-condensation device, so that the motor work safer; 5, two mechanical seals; model representation: qjb submersible mixer latest offer install the system: Selection Considerations: submersible mixer selection is a more complex task, selection of correct or not directly affect the normal use of the device, as the principle of selection is to get fit to play in the volume mixer in full The mixing function, generally available to determine the flow rate. According to the sewage treatment plant different process requirements, blenders should ensure optimal flow rate between 0.15 ~ 0.3m / s, the flow rate is less than 0.15m / s are not up to stirring effect plug flow, the flow rate of more than 0.3m / s of it will affect the results and wasteful process. So before the selection is first determined using submersible mixer places, such as: sewage, sludge pond, biochemical pool; followed by medium parameters, such as: suspended solids content, viscosity, temperature, PH value; there are pools of shape, water depth. Mixer required supporting power is based on the volume size, the density of the liquid and stir mixing depth determined, according to the specific circumstances of the use of one or more mixers. Mixing and stirring type: 1, the correction coefficient is determined to be stirred sludge medium according to FIG B1 or table B1. 2, to determine the cell-type stirring tank according to a correction coefficient table in Fig. B2 or B2. 3, the power consumption per cubic meter of water required 5 w, multiplied by the correction factor sludge, and then multiplied by the pool type correction factor to be drawn per cubic meter mixing power consumption required for the actual value of the medium, and then multiplied by the wait stir the medium volume, draw the entire pool to be mixing medium power required. Low-speed plug-flow type: 1, according to the table in Figure B1 or B1 stirred tank POND determine the correction factor. 2, the correction factor is determined to be stirred sludge medium according to FIG B2 or Table B2. 3. The initial velocity stirred media y, determined by the unit flow chart B3 power consumption. 4, with the initial flow rate y multiplied by stirred media cross-sectional area formed by rotation of the impeller stirrer calculated flow. 5, with the mixer unit traffic flow multiplied by the power, and then multiplied by the correction factor and sludge tank type correction factor required to obtain the entire pool of media power.
