diffusion pump parts
Diffusion pump parts constitute essential components of high-vacuum systems, working together to create and maintain the extreme vacuum conditions necessary for various industrial and scientific applications. The primary components include the pump body, jet assembly, heater, cooling coils, and fluid reservoir. The pump body, typically constructed from stainless steel, houses the intricate jet assembly system where the working fluid is vaporized and condensed. The jet assembly, consisting of multiple nozzle stages, directs the high-velocity vapor streams that capture and transport gas molecules. The heater element, positioned at the base, provides the thermal energy required to vaporize the working fluid, while the cooling coils maintain optimal temperature gradients throughout the system. The fluid reservoir stores and supplies the specialized pump fluid, usually a silicon-based oil with specific vapor pressure characteristics. These components work in concert to achieve vacuum levels as low as 10^-7 torr, making them invaluable in applications ranging from semiconductor manufacturing to scientific research equipment.
