Application of two-stage rotary vane pump in testing instruments

Shanghai Bodong PfeifferDouble stage rotary vane pumpApplied to testing instruments, providing vacuum solutions for determining material properties

The Importance of Measuring Material Characteristics
For many manufacturing processes and end products, it is crucial to have a precise understanding of the characteristics of the materials used The characteristics of materials include density particle size distribution, porosity, pore size distribution, and surface area or reactivity of catalysts Different materials have different characteristics, which not only determine the purpose of the material, but also determine which material is suitable for manufacturing and producing products, which surface effect should be achieved, and the production cost of the product Only by understanding the characteristics of materials can we avoid material failure during use
For example, in industries such as chemical engineering, food, pharmaceuticals, geology, and materials research, it is necessary to accurately know the characteristics of materials used in manufacturing processes And analyzing these characteristics requires reliable and highly accurate detection instruments, which all require a stable vacuum environment for sample preparation and sample evacuation during the analysis process Shanghai Bodong PfeifferDouble stage rotary vane pumpDuoLine is widely used in detection instruments, providing vacuum solutions for determining material properties

Shanghai Bodong PfeifferApplication of rotary vane pumpCustomer Case:McMurdrick Limited's testing instruments require rotary vane pumps to meet high reliability, longer maintenance intervals, and lower noise levels. Ultimately, Pfeiffer two-stage rotary vane pumps were chosen to provide the required vacuum environment!

Pufa rotary vane pumpApplication in determining material properties
When conducting material testing PfeifferRotary vane pumpDuoLine is used for sample preparation and physical adsorption measurement, providing a vacuum environment of up to 10-2 mbar to evacuate the sample in the measurement container and remove interfering volatile deposits under medium vacuum and elevated temperature Measure adsorption by adding adsorption gas (e.g. N2, at 77K, i.e. -196 ⁰ C) at a constant temperature If the fixed space and the measured gas quantity and pressure are known, the proportion of gas adsorbed on the material surface can be calculated over the entire pressure range

In addition to Pfeiffer, which is used to provide a vacuum environmentRotary vane pumpIn addition, it can also be paired with OmniStarOnline gas mass spectrometerUsed for chemical adsorption If several products are formed through chemical adsorption reactions, it is no longer possible to distinguish between reactive gases and by-products OmniStar can be used for gas analysis here, which helps to qualitatively distinguish and quantify gas types
