This section provides overview, applications, and principles of aspirators. Also, please take a look at the list of 17 aspirator manufacturers and their company rankings.
An aspirator is a device that generates a vacuum through the Venturi effect by using compressed air from a compressor.
Unlike vacuum pumps and other vacuum generating devices with complex mechanical structures, aspirators are characterized by their simple vacuum generating structure inside that uses the Venturi effect. Compressed air used in production is used to generate the Venturi effect, and the ejector provides the vacuum necessary for lifting parts.
Aspirators are generally not used as stand-alone devices, but are used with a suction pad at the end of the vacuum line extended by the aspirator. The shape and material of the suction pad must be selected according to the weight, size, and material of the workpiece, but the aspirator and suction pad are used to pick up parts and transport workpieces.
Aspirators and suction pads are also used to pick up and transfer heavy objects such as windshields in automobile production plants.
Unlike vacuum pumps and other vacuum generating devices with complex mechanical structures, aspirators feature a simple vacuum generating structure based on the Venturi effect inside.
The structure of an aspirator consists of a compressed air inlet, nozzle, diffuser, and compressed air outlet in a straight line, with a vacuum generation line installed vertically between the nozzle and diffuser to create the Venturi effect.
The principle of vacuum generation by the Venturi effect is that the nozzle, which has a smaller diameter than the compressed air inlet, squeezes the fluid at high speed, causing the pressure to drop in the space between the nozzle and the diffuser, which simultaneously generates a vacuum. The vacuum generated in the space between the nozzle and diffuser is obtained by the vertical vacuum line, and at the same time, the mixture of suctioned fluid and compressed air is discharged toward the diffuser and outlet at a high speed to obtain a high vacuum.
