The power of the vacuum is something that most people are extremely familiar with, in the form of that modern cleaning appliance that makes picking up stray bits of dirt and dust so easy. There are many other ways that we make use of vacuum in our daily lives yet seldom realize. If you have ever hung something up on a hook attached to a tile on the wall or fixed your in-car navigation unit to the inside of the windshield using the provided suction cup, then you were making use of vacuum technology. Convum suction cups and Convum vacuum pads take that technology one step further, applying pneumatic technology to create an active vacuum instead of merely a passive one. A passive vacuum refers to a vacuum created when air has been forced out of a space and prevented from returning by non-active means. In the case of a regular suction cup, when it is pressed glass or some other smooth surface, the air under it is pushed out and the seal formed between the edges of the cup and the surface prevents air from returning, without any further need for expenditure of effort on your part. How It Works Pneumatic suction devices work on the principle of creating a vacuum. Since it cannot simply depend on a passive vacuum, particularly if the object being picked up does not have a regular surface and a proper seal cannot be formed by the suction cup, it is necessary for the air to constantly be sucked into the cup. This is accomplished in much the same manner as a household vacuum cleaner does, with a motor that drives the air in one direction, so that more air is pulled up through an attached hose, which in this case is attached to a suction cup. Industrial Applications Vacuum-based equipment is used in industries that require a more delicate mechanical means of picking up objects and products than grippers can provide. Mechanical grippers are widely used to pick up and shift objects and raw materials through an assembly line or factory line, but if the materials are fragile, such as glass, then a mechanical gripper would most likely damage it. Suction, however, provides the means by which even fragile objects can be picked up by a machine without causing any damage. One of the good things about pneumatic suction devices is that the strength of the lift provided can be modulated by regulating the air pressure. If less air is drawn through the suction device, then the vacuum force created will be weaker. It is important in industrial applications to allow for some leeway, however, instead of making the suction force only just as strong as is necessary to lift whatever objects need to be lifted. Convum suction cups and Convum vacuum pads are at the very cutting-edge of pneumatic suction technology, and they can be of great use in pneumatic systems to handle delicate and fragile objects. When it comes to pneumatic suction devices, there are none better than Convum suction cups , Convum vacuum pads and other products developed by Convum, all of which are available from DAS Services Inc!
