The vacuum suction pad is a pneumatic actuator element with a sealing lip that forms a temporary sealed space when in contact with the suction object. It works by removing or thinning the air inside the sealed space to create a difference in internal and external pressure.
Vacuum suction cups can be classified into flat suction cups, oval suction cups, corrugated suction cups, and special-shaped suction cups based on shape, with corrugated suction cups further subdivided into double-layer vacuum suction cups, triple-layer vacuum suction cups, and multi-layer vacuum suction cups depending on the thickness of the sealed space. They can also be classified into pneumatic vacuum suction cups and manual vacuum suction cups based on the method used to remove or thin the air in the sealed space. The special structure of the vacuum suction cup allows a temporary sealed space to be formed when in contact with an object.
We can remove or thin the air inside the sealed space through a pneumatic circuit or a certain device. This will create a lower pressure in the sealed space than the atmospheric pressure outside. The outside atmospheric pressure will firmly press the object and the vacuum suction cup together. This is how we see the vacuum suction pad holding the object.
The application of vacuum suction cups is widespread and they can even be used in very special environments. However, special maintenance and precautions should be taken when using vacuum suction cups in special environments.
Use in low-temperature environments
When using vacuum suction cups in environments below 5℃, measures such as installing air dryers should be taken to prevent the solidification or freezing of the condensed water or water vapor in compressed air.
Shock and vibration
The shock applied to the vacuum element product should be less than 150m/s, and the vibration should be less than 40m/s. If it exceeds this value, it will cause misoperation.
The wiring of pressure sensors and other components should be kept away from high-voltage power machines, high-voltage lines, and power lines with larger interference. Otherwise, it will cause misoperation or failure.
Do not use in environments containing corrosive gases, chemicals, seawater, water, or water vapor, or environments containing these substances.
When exposed to direct sunlight, use a protective cover to block the sunlight.
When there is a heat source nearby, cut off the radiant heat.
When installing the solenoid valve on the control panel, take measures to dissipate heat to meet the temperature range specified in the product specifications.
When welding in an area with flying sparks, use a protective cover to prevent damage to the plastic parts of the solenoid valve, which can easily cause a fire.
If water droplets or other fluids directly drop onto the solenoid valve, it will cause leakage and coil burnout. Pay attention to protection, and install a protective cover or place the solenoid valve inside the control panel.
