The main factors affecting the performance of vacuum suction cups include the following aspects:
1. Vacuum degree (negative pressure)
The higher the vacuum degree, the stronger the suction capacity of the suction cup. Affected by the efficiency of the vacuum pump, leakage, and pipeline sealing.
2. Suction cup material and structure
Material selection: such as silicone, rubber, polyurethane, different materials are suitable for different surfaces (rough, smooth, high temperature, etc.).
Structural design: The diameter and shape (flat, corrugated) of the suction cup determine the adsorption capacity and applicable scenarios.
3. Surface characteristics of the adsorbed object
1) Surface roughness: Smooth surfaces (such as glass) are more firmly adsorbed, and rough surfaces may cause air leakage.
2) Material: Porous materials (such as cartons, foam boards) are difficult to form a stable vacuum.
3) Shape: Flat surfaces are easier to form a vacuum than curved or irregular shapes.
4. Vacuum generation system
1) Capacity of vacuum pump or vacuum generator: flow, pressure, and response speed affect adsorption.
2) Pipeline design: Too small a pipe diameter, too long a pipe, and too many bends will affect vacuum efficiency.
3) Sealing performance: Leakage of joints, valves, and hoses will reduce the adsorption capacity.
5. Environmental factors
1) Temperature: High temperature may affect the flexibility of the suction cup material, and low temperature may make it brittle.
2) Humidity: Moisture may affect the sealing and reduce the adsorption force.
3) Dust and pollution: Dust and oil may cause poor sealing and affect the vacuum holding ability.
6. Load and working pressure
Load weight: The suction cup needs to match the appropriate load capacity, and overload may cause it to fall off.
Working pressure: The pressure of the vacuum source must be stable, otherwise it will affect the adsorption effect.
Optimizing these factors can improve the adsorption stability and work efficiency of the vacuum suction cup.
