Suction cups are very common in our lives, but we may not know much about electric suction cups. In fact, the electric suction cup, also known as the vacuum spreader, is composed of a vacuum pump and a suction cup. It is one of the vacuum equipment actuators. It is a common component in the vacuum system and a product widely used in automation. Today, I will tell you how the electric sucker sucks firmly, and I hope it can bring you some help.

First understand the working principle of the electric suction cup hook. It can suck the wall because it discharges the air inside the suction cup when the suction cup is squeezed, so that the air pressure inside the suction cup is much lower than the outside air pressure, so that the external surface of the suction cup is extremely large The pressure presses the suction cup against the wall. If the wall surface is not smooth enough (dust, oil, stains, etc.), the outside air will be pressed into the suction cup through the small gap between the suction cup and the wall, and the internal air pressure will increase, while the external atmospheric pressure will not change. In this way, the pressure difference between the inside and outside is reduced, and the pressure on the outer surface of the suction cup is reduced. The suction cup is naturally easy to fall off, so it is better to suck it on a smooth surface.

How can I suck it firmly on the wall? First, wipe clean the adsorbed surface, and then dip some water on the adsorbed surface, so as to fill these small gaps. Because the surface of the water has tension, the pressure acting on the suction cup is not enough to overcome this tension, so the air is not It will enter the inside of the suction cup through these small slits to form a vacuum environment, which solves the problem that the suction cup is easy to fall off.

This is the end of the article on how to suck the electric sucker firmly. I believe everyone has already understood it. If you have any other questions, please contact us.
