VACCUM EJECTOR

A pneumatic vacuum ejector (also known as a vacuum generator or venturi vacuum pump) is a compact, reliable device used to create a vacuum in a pneumatic system by utilizing the Venturi effect. ??? Operating Principle Supply: Compressed air is supplied to the ejector's inlet port. Venturi Nozzle: The air passes through a specially designed Venturi nozzle, causing it to accelerate and create a low-pressure zone. Vacuum Port: This low pressure is connected to a dedicated vacuum port, drawing air out of the connected vacuum line or chamber (e.g., suction cup). Exhaust: The supplied air and the drawn air are then exhausted to the atmosphere through a separate port. ?? Key Features and Applications Compact & Lightweight: They are smaller and lighter than mechanical vacuum pumps, making them ideal for robotics and small-scale automation. No Moving Parts: Because they use the Venturi principle, they have no mechanical moving parts, resulting in minimal maintenance and long service life. Applications: They are widely used for pick-and-place applications in manufacturing, especially when used with suction cups to grip and move non-porous objects like glass, metal sheets, and plastic components.
