Sewage mixer purchase precautions can be summarized as follows:

First, understand the composition of sewage and treatment needs

Before purchasing a sewage mixer, we must first understand the chemical composition of sewage, pH and treatment objectives. This information will help determine the type of mixer, material and power required.

Second, choose the right type of mixer

According to the nature of sewage and treatment needs, choose the appropriate mixer type, such as propulsion, paddle, turbine, screw, etc. Different types of mixers have different mixing effects and scope of application.

Third, consider the corrosion resistance of the mixer

Since the sewage may contain acidic substances and chemical components, the material of the mixer should have sufficient corrosion resistance. For example, for highly corrosive sewage, you can choose a mixer made of corrosion-resistant materials such as stainless steel.

Fourth, pay attention to the structure and design of the mixer

1. The structure of the sealing box, stirring reactor and agitator should be reasonable to avoid unnecessary injury during operation.

2. Pay attention to whether the power of the motor and stirring reducer match the volume of the tank to avoid premature aging of the equipment caused by overload operation.

Fifth, ensure the appropriate installation position and maintenance

1. The installation position of the mixer should be considered when purchasing to ensure that it can play a full role and reduce interference with normal operation.

2. Maintain the mixer regularly to ensure its long-term stable operation.

Sixth, consider price and cost performance

In the purchase, in addition to paying attention to the performance and quality of the mixer, but also consider its price and cost performance. Choosing cost-effective products can help reduce the cost of sewage treatment.

To sum up, when purchasing a sewage mixer, you need to pay attention to the nature and treatment needs of the sewage, choose the right type of mixer, consider the corrosion resistance, pay attention to the structure and design, ensure the appropriate installation location and maintenance, and consider the price and cost performance factors. These precautions will help you choose a sewage mixer that suits your needs.
