Nine, QJB-diving flowmakers Selection Considerations: Selection submersible mixer is a relatively complex task, normal use or not directly affect the selection of the right equipment, the principle is to make a selection in the submersible mixer stirred for a sufficient volume in function of the flow rate can generally be determined. According to the sewage treatment plant different technical requirements, submersible mixer should ensure optimum flow rate between 0.15 ~ 0.3m / s, the flow rate is less than 0.15m / s streams are not up to push the stirring effect, more than 0.3m / s of the effect of the flow rate will affect the process and wastage. So before the selection is first determined using submersible mixer QJB places, such as: sewage, sludge pond, biochemical pool; followed media parameters, such as: suspended solids content, viscosity, temperature, PH value; still pond shape , depth of installation and so produce even influence the selection, while also taking into account the energy efficiency factor, because this will affect the future operating costs to the user. Refer to the following submersible mixer flow field map. To ensure the best results submersible mixer, use a square to provide the following information: 1, the use of purpose 2, type 3 pools, pool size 4, media properties including viscosity, density, solids content. Submersible mixer matching power is required according to the volume size, the density of the liquid is stirred, the viscosity and mixing depth determined, should be used depending on the circumstances one or more mixer. Note: 1, selection problems, please contact our technical department. 2, submersible mixer work must be completely submerged in water, not in an explosive atmosphere or corrosive liquids environmental work, the minimum immersion depth 900mm. Ten, QJB submersible mixer Selection Method References: 1, according to Figure 1 or Table 1 to determine the sludge correction factor to be stirred media. 2, to determine the cell-type mixing tank 2 or the correction coefficient in accordance with Table 2. 3, the power consumption per cubic meter of water required to 4.8W, the correction coefficient is multiplied by the sludge, and then multiplied by the correction coefficient POND, per cubic meter to be obtained mixing the power consumption required for the actual value of the medium, and then to be multiplied stirring volume media, draw the entire pool to be medium mixing power required.

Thirteen, QJB submersible mixer running live: compared with traditional long axis of the mixer, the advantages QJB submersible mixer that can produce different flow. By different installation location mixer, multiple flow pattern obtained different effects. Thus in the pool to create a better flow patterns, eliminate stir corner. Blender supporting power is needed by the pool volume size, density of the medium, medium viscosity and pull row depth determined according to their body conditions should be used in one or more mixers. In order to ensure mention mixing machine running in different type of energy-efficient pool. Typical installation can refer to the following form. Round pool: the rotating cylinder flow equation is the most single one. Phase within a shorter operating time on the creation of high velocity, high solids insoluble in the medium, which is an efficient mixing methods. However, it must be noted that the heavier material may be deposited in the bottom center. The rotation is the most single-cylinder flow formula one. Phase within a shorter operating time on the creation of high velocity, high solids insoluble in the medium, which is an efficient mixing methods. However, it must be noted that the heavier material may be deposited in the bottom center. If the axis of the cell line mixer into 7-10 ° installation, pull the entire pool can be formed without causing rotation mix. Depth of the pool of the liquid to be 0.3 to 1 times the diameter of the pool between. Diagonally staggered to avoid short-circuiting the cycle square pool: If the figure mounted mixer in a square pool formation and efficient stirring effect. When using a blender, pool aspect ratio of not more than five. Otherwise it should be installed multiple mixer. If the aspect ratio is not greater than 2.5 to obtain the best operating results. Such as the case of the impeller is less than 5-8 times the width of the pool, while a larger map pool installation, mixers can be installed on a map using the wall reflection considering export jet cross using multiple mixers, according to the recommended QJB submersible mixer product advantages compared with similar products: Mixing plug flow equipment market similar products in 1 developed high starting point, intellectual property and more equipment to increase the capacity of domestic, import substitution as any, independent innovation to meet the requirements of market segments series products.
