Chemical corrosion-resistant diaphragm pumps have shown excellent performance in terms of chemical corrosion resistance, pumping performance, structural design, intelligent control, and application scenarios. The following is a detailed study of their performance:
1、 Chemical corrosion resistance
Material selection: All parts of the chemical corrosion-resistant diaphragm pump that come into contact with gas are made of chemically corrosion-resistant materials, such as polytetrafluoroethylene (PTFE), fluororubber (FKM), etc. These materials have excellent chemical corrosion resistance and can safely withstand corrosive gases such as strong acids, alkalis, and organic solvents.
Application scenarios: This chemical corrosion resistance makes chemical corrosion-resistant diaphragm pumps widely used in industries such as chemistry, pharmaceuticals, petrochemicals, etc., such as filtration, vacuum distillation, rotary evaporation, vacuum concentration, centrifugal concentration, solid phase extraction, etc.
2、 Extraction performance
Extraction speed: Chemical corrosion-resistant diaphragm pumps have a high extraction speed, which can meet the extraction needs in different scenarios. For example, some models of pumps can achieve a maximum pumping speed of 12.1/13.3m ³/h at 50/60Hz.
Extreme vacuum: This type of pump can achieve a lower ultimate vacuum, such as some models of pumps with an ultimate vacuum (absolute pressure) of 2mbar/1.5torr, suitable for applications that require high vacuum levels.
Stability: Chemical corrosion-resistant diaphragm pumps exhibit good stability during the pumping process, and can continuously and stably provide the required vacuum degree.
3、 Structural Design
Oil free design: The chemical corrosion-resistant diaphragm pump adopts an oil-free design, which avoids the pollution of oil stains on the vacuum environment and ensures a clean vacuum environment.
Sealing performance: This type of pump has excellent sealing performance, with no direct contact between the liquid and the driving mechanism, reducing the possibility of leakage and improving the safety and reliability of the equipment.
Modular design: Some chemical corrosion-resistant diaphragm pumps adopt modular design, which facilitates maintenance and component replacement, reducing maintenance costs and time.
4、 Intelligent control
Automated regulation: Some models of chemical corrosion-resistant diaphragm pumps are equipped with automated vacuum regulation function, which can automatically adjust the vacuum degree according to actual needs, improving the stability and efficiency of the process.
Intelligent monitoring: Some pumps are also equipped with intelligent monitoring systems that can detect the running status of the pump in real time, determine whether there are leaks or faults, and issue alarms, greatly improving the safety and efficiency of operation and maintenance.
5、 Application scenarios and case analysis
Chemical synthesis: During the chemical synthesis process, a corrosion-resistant diaphragm pump can be used for filtration and solvent recovery in the reaction vessel, ensuring the smooth progress of the synthesis process.
Pharmaceutical industry: In the pharmaceutical industry, this type of pump can be used in processes such as vacuum drying and distillation concentration, improving the production quality and efficiency of drugs.
Laboratory application: In the laboratory, chemical corrosion-resistant diaphragm pumps are often used in conjunction with equipment such as rotary evaporators and vacuum drying ovens, providing a stable and reliable vacuum environment for experiments.
