Electric suction cups can be seen in many occasions. From the point of view of its working performance, it is because the compressed air is jetted at high speed through the nozzle and the entrainment effect is generated around the nozzle to generate a vacuum, and then the function of the electric suction cup is obtained. Everyone knows how to use and maintain electric suction cups. Let's introduce the factors that affect the performance of electric suction cups.
1. Adequacy of air supply flow
The vacuum generator of the electric suction cup is an original part that consumes compressed air. When the air supply is insufficient, it will lead to a lack of vacuum. Pay special attention to the electric suction cups with larger specifications. So everyone must do a good job of calculating the air consumption of the entire electric suction cup device. The lack of air supply will also lead to the lack of cylinder output and slow movement. The cross-sectional area of the air inlet piping of the vacuum generator should be several times larger than the cross-sectional area of the nozzle to maintain sufficient air flow and stable air supply pressure. Although the diameter of the electric suction cup represents the outer diameter of the suction cup, when vacuum pressure is applied to suck the object, the rubber will be deformed due to the vacuum pressure, and the suction area will be reduced accordingly. The reduced area is called the effective suction area, and the suction cup diameter at this time is called the effective suction cup diameter.
2. The patency of exhaust and suction
When nozzles and mufflers are blocked, it will cause a lack of vacuum. Therefore, the filter element of the electric suction cup and the filter element should be changed regularly; the pipeline of the electric suction cup (from the generator to the suction cup) should be shortened as much as possible, and the pipe diameter should be large without too much bending , If the flow is not smooth, it will form adsorption and affect the stability of the operation. Electric suction cups have a shorter lifespan during use, but fortunately, the operating temperature range of silicone rubber is wider, but its performance is stable when working under hot and humid conditions. Except for excessive use, it is mostly caused by heat or sunlight, so the suction cup is easy to keep in a cool and dark room.
All in all, the two factors that affect the performance of the electric suction cup are the adequacy of the air supply flow and the patency of the exhaust and suction. The future development prospect of electric suction cups mainly lies in the development prospect of suction of suction cups. It is determined by the degree of vacuum and the area of the suction cup. First of all, everyone must ensure that the electric suction cup is in good contact with the surface of the suction workpiece and maintain good air tightness.
