Pneumatic diaphragm pump is a common type of pump equipment that drives diaphragm vibration through compressed air to achieve liquid transportation. The diaphragm is a very important component in pneumatic diaphragm pumps, which determines the performance and lifespan of pneumatic diaphragm pumps.
As a key component of pneumatic diaphragm pumps, the diaphragm needs to have certain physical characteristics. Firstly, it needs to have good corrosion resistance and be able to withstand the erosion of various chemical media. Secondly, it needs to have a certain degree of elasticity and wear resistance, and be able to withstand high-frequency vibration and long-term use. Finally, it also needs to have certain sealing performance to effectively prevent leakage and pollution.
At present, the common membrane materials on the market mainly include fluororubber, chloroprene rubber, silicone rubber, and polytetrafluoroethylene. Among them, fluororubber has excellent corrosion resistance and high temperature resistance, suitable for transporting chemical media such as strong acids and alkalis; Neoprene rubber has excellent wear resistance and elasticity, suitable for conveying abrasive media; Silicone rubber has excellent high-temperature resistance and oxidation resistance, suitable for conveying high-temperature and oxidizing media; PTFE has excellent corrosion resistance and high-temperature resistance, suitable for transporting extremely strong acids, alkalis, and high-temperature media.
In addition to material selection, the design of the diaphragm is also very important. A reasonable diaphragm structure can reduce pump energy consumption and noise, improve pump efficiency and lifespan. Usually, the design of a diaphragm needs to consider the following factors:
Thickness: The thickness of the diaphragm needs to be determined based on the working conditions of the pump and the properties of the medium. An excessively thick diaphragm will affect the output flow of the pump, while an excessively thin diaphragm is prone to wear and tear.
Aperture: The size and quantity of aperture on the diaphragm also need to be determined based on the working conditions of the pump and the properties of the medium. Excessive or insufficient aperture can affect the output flow rate and pump life.
Strength: The strength of the diaphragm needs to be sufficient to withstand high-frequency vibration and long-term use, while also having a certain degree of elasticity to ensure the output flow rate and pump life.
Material: Select appropriate materials based on the properties of the medium and the working conditions of the pump to ensure the corrosion resistance, wear resistance, and high temperature resistance of the diaphragm.
In short, as a key component of pneumatic diaphragm pumps, the diaphragm needs to be selected with appropriate materials and designed with a reasonable structure to ensure the performance and lifespan of the pump. In practical applications, it is necessary to select the diaphragm based on specific working conditions and the properties of the medium to ensure the safe and stable operation of the pump.
