Of course it’s an axial flow pump!!!! Our company has them, but they are entirely imported
Use an axial flow pump with low speed, high flow rate, and low head. Overall, foreign products are still better; the difference becomes more noticeable the larger the product. Whether it’s efficiency, mechanical seals, flow rate, or other aspects. However, the price is indeed much higher.
Chemical axial flow pumps can be connected directly or via a belt, depending on the site conditions.
Choose a high-flow axial flow pump with a head of 4 meters
What was said upstairs is correct; the head is generally 4 to 5 meters, and the flow rate is several hundred cubic meters.
Well, basically, axial flow pumps will work just fine
The evaporator uses a forced circulation pump, which is of course an axial flow pump. The flow rates mentioned above are too low; even the smaller ones amount to several thousand cubic meters per hour. Domestic manufacturers include Dalian Sulzer Pump and Compressor Factory and Sichuan Xinda Group Co., Ltd.
Choose a pump with high flow rate and low head; an axial flow pump is an excellent choice. Flow rate: Calculated based on 2 meters within the heat exchange tube; a head of 4 meters is sufficient.
The flow rate inside the heat exchange tubes is determined based on the properties of the material; the actual flow rate we use is 1 meter per second, and it works well.
