Service life of rotary film deaerator

A rotary film deaerator is a common industrial device used to remove oxygen from water. It rotates the film to achieve a physical separation between oxygen and water molecules, effectively reducing the oxygen content of the water. However, the service life of a rotary film deaerator is an important consideration, as it directly affects the performance and economic benefits of the equipment.

1. Water quality will affect the life of the rotary film deaerator

First of all, the service life of the rotary film deaerator is affected by many factors. One of them is the impact of water quality. The oxygen content, hardness, PH value and the content of suspended matter in the water will affect the life of the rotary film deaerator. Water with high oxygen content will cause the oxygen permeability of the membrane to decrease, which will affect the deaeration effect. In addition, the hardness and PH of the water are too high, which can also lead to blockage and wear of the diaphragm, further shortening the service life. Therefore, regular detection and adjustment of water quality is an important measure to ensure the long life of the rotary film deaerator.

2. The material and structure of the rotary film deaerator will affect its service life

Secondly, the material and structure of the rotary film deaerator will also affect its service life. High quality materials and reasonable structural design can improve the corrosion resistance and wear resistance of the deaerator, thus extending its service life. Some common material choices include stainless steel, ceramics and polymers, which have good chemical stability and wear resistance. In addition, reasonable structural design can reduce the stress and fatigue of the diaphragm, thus slowing down the aging rate of the diaphragm. Therefore, when selecting a rotary film deaerator, the quality of its material and structure should be considered.

3. The correct operation and maintenance will affect the life of the rotary film deaerator

In addition, the correct operation and maintenance is also the key to ensure the service life of the rotary film deaerator. The operator should strictly follow the operation manual of the device to avoid high or low oxygen flux and high water pressure. In addition, regular maintenance and cleaning of the deaerator is also an important step to extend the service life. Clogging and wear of the diaphragm are common problems that can be solved by cleaning and replacing the diaphragm regularly. At the same time, regular inspection and maintenance of other components of the equipment, such as pumps and valves, is also key to ensuring the normal operation of the deaerator.

4. Regular testing and evaluation will affect the life of the rotary film deaerator

Finally, regular testing and evaluation of the performance of the deaerator is also an important means to extend the service life. By regularly testing the deaeration effect and water quality of the deaerator, problems can be found in time and corresponding measures can be taken. In addition, regular evaluation of the performance and economic benefits of the deaerator can determine whether it needs to be repaired or replaced in time. Through timely maintenance and update, the good performance and long life of the deaerator can be maintained.

In summary, the service life of a rotary film deaerator is affected by a variety of factors, including water quality, material and structure, operation and maintenance, and performance evaluation. In order to ensure the long life of the deaerator, we should regularly test and adjust the water quality, select high-quality materials and reasonable structural design, correctly operate and maintain the equipment, and regularly evaluate the performance and economic benefits of the deaerator. Only by taking these factors into consideration can we maximize the service life of the rotary film deaerator and improve its performance and economic benefits.
