AI Technical Summary
Existing ejector-type vacuum pumps face challenges in efficiently managing vacuum levels for gripping operations with leaking surfaces and materials, leading to high energy consumption and potential object loss, while maintaining precise control over vacuum pressure is difficult due to friction-induced slipstick behavior.
An ejector-type vacuum pump assembly with a stabilized membrane flow valve system that uses a pilot flow of pressurized air to regulate the main flow, incorporating a pressure sensor and control unit to adjust the vacuum level dynamically, eliminating sliding parts and relying on air pressure for control, thus minimizing energy consumption and friction-related issues.
The system achieves precise control of vacuum levels with reduced energy use, minimizing wear and fluctuations, ensuring stable gripping operations even with leaking materials, and allowing for efficient size and airflow management.
