VISelection precautions:

Selection is a complex task, and the correctness of the selection directly affects the normal use of the equipment. The principle of selection is to ensure that the mixer can fully perform its mixing function in the appropriate volume, which can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants, the flow rate of the mixer should be ensured between 0.15~0.3m/s. If the flow rate is lower than 0.15m/s, the push flow mixing effect cannot be achieved. If the flow rate exceeds 0.3m/s, it will affect the process effect and cause waste. So before selecting, first determine the location where the submersible mixer will be used, such as sewage tanks, sludge tanks, and biochemical tanks; Next are the parameters of the medium, such as suspended solids content, viscosity, temperature, and pH value; Also, the shape and depth of the pool. The required matching power of the mixer is determined by the volume, density of the mixed liquid, and mixing depth, and one or more mixers are used according to the specific situation.

7、 Mixed mixing type

Determine the sludge correction factor for the medium to be mixed based on Figure B1 or Table B1.

2. Determine the tank type correction factor for the mixing tank based on Figure B2 or Table B2.

According to the required power consumption of 5 watts per cubic meter of clean water, multiply by the sludge correction factor, and then multiply by the tank type correction factor to obtain the power consumption for mixing and stirring per cubic meter

The actual value of power consumption required for mixing the medium is multiplied by the volume of the medium to be mixed to obtain the power required for the entire tank of mixed medium.

8、 Low-speed thrust flow pattern

Determine the tank type correction factor for the mixing tank based on Figure B1 or Table B1.

Determine the sludge correction factor for the medium to be mixed based on Figure B2 or Table B2.

Based on the initial flow rate y of the stirring medium, determine the power consumption per unit flow rate through Figure B3.

Calculate the flow rate of the mixer by multiplying the initial flow rate y of the stirring medium by the cross-sectional area formed by the rotation of the impeller.

Multiply the flow rate of the mixer by the power consumption per unit flow rate, and then multiply by the sludge correction factor and tank type correction factor to obtain the total amount of medium in the entire tank

Required power.
