How do the breathability and resistance characteristics of Polyester Needle Punched Filter Felt affect the performance of the filtration system?

1. The influence of breathability on the performance of filtration systems
Improve filtration speed:
Polyester needle punched filter felt with good breathability can reduce resistance during the filtration process, allowing liquids or gases to pass through the filter material more quickly, thereby improving filtration speed. This helps to improve the overall processing efficiency of the filtration system, especially when dealing with large amounts of fluids.
Reduce energy consumption:
Filter media with poor breathability will increase the resistance during the filtration process, resulting in the filtration system needing to consume more energy to overcome these resistances. On the contrary, polyester needle punched filter felt with good breathability can reduce the energy consumption of the filtration system, thereby saving a lot of energy costs for enterprises.
Improving the quality of filter cake:
Using breathable polyester needle punched filter felt can make the filter cake more uniform and delicate, improving the quality of the filter cake. At the same time, the discharge of filter cake is also smoother, reducing the clogging and cleaning frequency of filter cloth, and extending the service life of filter cloth.
2. The influence of resistance characteristics on the performance of filtration systems
Impact on filtration efficiency:
Resistance characteristics are one of the important indicators for measuring the filtration performance of filter media. Filter media with excessive resistance can lead to a decrease in filtration efficiency, as too much energy is consumed to overcome resistance rather than being used in the actual filtration process. Therefore, selecting a polyester needle punched filter felt with suitable resistance characteristics is crucial for ensuring the efficient operation of the filtration system.
Increase system burden:
Filter media with excessive resistance can also increase the burden on the filtration system, making it more prone to malfunctions and wear. This will increase the maintenance cost of the system and may affect its stability and reliability.
Affects fluid pressure:
The resistance characteristics also affect the pressure of the fluid in the filtration system. Filter media with excessive resistance can cause an increase in fluid pressure, which may impose additional pressure on other components of the system and even lead to system damage.
