intro
Vacuum components with vacuum pressure as a power source, as a means to achieve automation, has been widely used in electronics, semiconductor component assembly, automotive assembly, automatic handling machinery, light industry machinery, food machinery, medical machinery, printing machinery, plastic products machinery, packaging machinery, forging machinery, robots and many other aspects.
The vacuum generator has two kinds of vacuum pump and vacuum generator. Vacuum pump is a suction inlet to form negative pressure, the exhaust port directly through the atmosphere, the pressure ratio at both ends is very large pumping gas machinery. Vacuum generator is the use of compressed air flow to form a certain degree of vacuum pneumatic components, compared with the vacuum pump, its simple structure, small size, light weight, low price, easy installation, easy to combine with accessories, vacuum generation and release fast, should be engaged in small flow intermittent work, suitable for dispersed use
principle
The vacuum generator is a new, efficient, clean, economical and small vacuum component that uses a positive pressure air source to generate negative pressure, which makes it easy and convenient to obtain negative pressure where there is compressed air, or where both positive and negative pressure are needed in a pneumatic system. Vacuum generators are widely used in industrial automation machinery, electronics, packaging, printing, plastics and robotics and other fields.
The traditional use of the vacuum generator is the suction cup, for the adsorption of various materials, handling, especially suitable for the adsorption of fragile, soft, thin non-iron, non-metallic materials or spherical objects. In this type of application, a common feature is that the required suction volume is small, the vacuum requirement is not high, and the intermittent operation. The analysis and research of suction mechanism of vacuum generator and factors affecting its working performance have practical significance for the design and selection of positive and negative pressure gas paths. Automatic selection of vacuum generator is included.
