A launch vehicle uses a turbopump that is driven by a hot gas turbine. Due to high levels of horsepower, RPM, flow rates and pressures in this system, specific design features, materials, and fabrication methods must be used to ensure high performance as well as space flight levels of reliability. For static sealing applications in this area, metal seals are used to prevent leakage of a fluid through a joint that has no relative motion of the mating surfaces.
Piston cup seals are critical due to two functions. Firstly, the seal must function as a bearing. If the seal is removed from the hardware, the piston will hit against the cylinder wall. Secondly, since compressors need to run completely dry, the seal provides leakage and wear control.
Supercritical Fluid Chromatography (SFC) with CO₂ Medium
A growing global market trend is the increase in pharmaceutical manufacturing and supercritical fluid chromatography (SFC) for purity testing. Many chemicals used in medicinal pharmaceuticals occur in extremely low concentrations and can be difficult to detect with accuracy. Analyses of these compounds are typically performed using gas chromatography (GC) or liquid chromatography (LC).
At different speed regimes in the jet engine, the airflow in the compressor is regulated by variable stator vanes (VSV), which are generally located at the initial stages of the high pressure compressor. This area experiences relatively high pressure and high temperaturethat progressively increases with modern engine performances.
Flying a helicopter in an unpredictable and changing environment such as the desert or above the sea can lead to the accumulation of several kinds of potential aggressive contaminants, which are not clearly visibly on the bearings of the main shaft of a helicopter rotor. These damaging substances may cause jamming, ultimately leading to crash. The sealing of the swashplate is critical as it protects this aviation equipment from dust, sand, and debris.
100% (CO₂) Certified Fluoropolymers For Carbon Capture & Storage Applications
Renewable Energy Solutions
Because Carbon Capture & Storage (CCS) can achieve significant carbon dioxide (CO2) emission reductions, this process is considered a key and viable option within the portfolio of approaches required to reduce greenhouse gas (CHG) emissions. CCS involves three major steps; capturing CO2at the source, compressing it for transportation, and then injecting into a deep reservoir at a carefully selected and safe site for permanent storage.
