Designing mechanical systems for high-volume manufacturing
Cryogenic LNâ‚‚ Reciprocating Pump System
Overview
Designed and developed a high-pressure cryogenic reciprocating pump system, integrating a customer-specified hydraulic drive for operation in a hazardous environment. Design considerations included high-pressure loading, cryogenic temperature effects, sealing performance, and vibration monitoring for system reliability.
Role & Contributions
Designed and validated a new crankshaft to meet updated load and drive requirements
Integrated a hydraulic motor drive system to meet customer requirements for hazardous-area operation
Developed new intermediate housings with integrated vibration and temperature sensor provisions for system monitoring
Designed supporting mechanical components for hydraulic integration, including mounting, coupling, and interface hardware
Coordinated mechanical interface with a new cold-end cylinder designed by a separate team
Created detailed assembly drawings and standard operating procedures (SOPs)
Supported factory acceptance testing (FAT) to verify system performance prior to shipment
