Main Hopper for Precision Propellant Metering and Charging Station

Product Specifications

Technical details and manufacturing context for Main Hopper

Definition

The Main Hopper is a component of the Precision Propellant Metering and Charging Station, serving as the central reservoir for bulk propellant material. It stores propellant and provides a controlled, consistent feed to downstream metering mechanisms, ensuring continuous material supply while maintaining propellant integrity through environmental protection features. The hopper is designed for use in other transport equipment manufacturing, where precise propellant handling is critical. It is available in Stainless Steel 316L or Aluminum Alloy, with material grade options of 304 or 316L per ASTM A240, depending on the corrosiveness of the propellant. The hopper has a capacity range of 500 to 2000 liters, with custom sizes available on request. Operating pressure ranges from 1.0 to 1.6 MPa per and operating temperature is -20 to 60 degrees Celsius, with non-freezing conditions and optional insulation. Dimensional tolerance is ±0.5 mm per ISO 2768-m, critical for metering accuracy. Electrical supply for level sensors and agitator is 24 V DC ±10%. Ingress protection is IP54 to IP65 per IEC 60529, suitable for washdown areas. Weight ranges from 150 to 450 kg, depending on capacity and material. Surface roughness is Ra 0.8 to 1.6 micrometers per ISO 4287, ensuring a smooth finish that prevents residue. Connection sizes are DN50 to DN150 per ISO 7005, with flanged or tri-clamp options. All listed parameters are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Propellant is loaded into the hopper and stored until needed. Controlled discharge is achieved through gravity feed, often assisted by vibration, agitation, or auger systems to prevent bridging and ensure consistent material flow to the precision metering unit. The hopper maintains material level and provides buffer capacity for continuous operation. The design includes environmental protection features to maintain propellant integrity, such as seals and insulation options. The hopper's discharge rate is influenced by the material's flow characteristics and the assist mechanisms. Level sensors monitor material level, and the agitator helps maintain uniform flow. The hopper operates within specified pressure and temperature ranges, and its structural integrity is ensured by material selection and manufacturing tolerances. Proper operation requires adherence to the specified electrical supply and ingress protection ratings. Maintenance signals include unusual flow interruptions, level sensor alarms, or visible wear on seals and agitator components. Failure boundaries include exceeding pressure or temperature limits, which could compromise the hopper's integrity, or using incompatible materials that may corrode or contaminate the propellant.
