Method for High-Pressure Pulsation Testing of Machinery Components

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for high-pressure pulsation testing of machinery components using ionic liquids instead of traditional oils as the pressure medium. The use of ionic liquids, which have much lower compressibility and higher temperature resistance, improves the efficiency and effectiveness of fatigue testing on components under pulsed high-pressure conditions.

Use CasesContent extracted from patent full text and abstract with AI.

• Fatigue testing of automotive engine components such as connecting rods, camshafts, and common-rail diesel parts
• Testing of turbine blades and other high-stress machine parts in aerospace or energy sectors
• Evaluation of large machinery components that require simultaneous high-pressure testing
• Assessment of new materials or components expected to endure high pressures and thermal loads
• Industrial quality control for mass-produced metal or composite parts

BenefitsContent extracted from patent full text and abstract with AI.

• Lower compressibility of ionic liquids allows for higher testing efficiency and throughput, enabling more components or larger parts to be tested with the same equipment.
• Improved temperature resistance enables testing at higher temperatures, which is beneficial for simulating real operating conditions.
• Increased test accuracy and reliability due to reduced losses and more stable pressure profiles.
• Enhanced chemical stability of ionic liquids minimizes risk of damage to machine parts and testing equipment.
• Potential for significant cost savings and reduced testing time by enabling the parallel testing of multiple components.
• Opportunity to use existing testing machines for testing larger components, eliminating the need for new equipment investment.
