Precautions for selecting a submersible mixer
The selection of a submersible mixer is a complex task, and the correctness of the selection directly affects the normal use of the equipment. As a principle of selection, it is necessary to ensure that the mixer can fully perform its mixing function within the suitable 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.
