Vacuum Generator/Valve for Suction Gripping

Product Specifications

Technical details and manufacturing context for Vacuum Generator/Valve

Definition

This vacuum generator/valve is a component used in end-effector systems for material handling. It generates vacuum pressure through ejector, pump, or venturi-based methods and regulates vacuum flow via integrated valves, enabling precise control of suction force. The device operates by creating a pressure differential: compressed air expansion (ejector type), mechanical displacement (pump type), or fluid dynamics (venturi type). Valves control vacuum generation, release, and maintenance cycles. Typical operating pressure is 0.3–0.7 MPa, achieving a vacuum degree of -80 to -90 kPa relative to atmospheric pressure. Air consumption ranges from 50 to 200 L/min at operating pressure. Response time from signal to full vacuum is 10–50 ms. For solenoid valve versions, supply voltage is 24 V DC ±10%, power consumption 1–5 W, and protection class IP54–IP65 (IEC 60529). Operating temperature is -5 to 60 °C (non-freezing). Body materials include aluminum alloy, stainless steel, and engineering plastics, with corrosion resistance depending on material choice. Weight ranges from 0.2 to 1.5 kg depending on size. These values are reference ranges; verify model-specific specifications with the manufacturer or supplier. The component is suitable for suction gripping in automation, packaging, and assembly. Selection inputs include required vacuum level, flow rate, response time, and environmental conditions. Interfaces typically include compressed air supply, electrical connections for solenoid valves, and vacuum ports. Verification questions: confirm operating pressure range, vacuum degree, air consumption, response time, supply voltage, power consumption, protection class, operating temperature, body material, and weight for the specific model. Maintenance signals include reduced vacuum generation, increased air consumption, or slow response. Failure boundaries include operation outside specified pressure, temperature, or voltage ranges, which may cause insufficient vacuum or damage.

Working Principle

The vacuum generator/valve creates a pressure differential to produce vacuum. In ejector types, compressed air expands through a nozzle, creating a low-pressure zone that draws in air. Pump types use mechanical displacement to evacuate air. Venturi types rely on fluid dynamics to create suction. Integrated valves control the vacuum generation, release, and maintenance cycles, allowing precise regulation of suction force. The device operates within specified pressure and temperature ranges to ensure reliable performance.
