Abstract

The invention provides an integrated type vacuum generator and a using method. The integrated type vacuum generator comprises an air supply device, a vacuum generating device and a control device. Thecontrol device comprises a vacuum pressure meter, a vacuum pilot valve, a destroying pilot valve, a valve element and a valve body. The vacuum generating device comprises an internally-arranged vacuum generating pipe and a vacuum cavity. The valve body is provided with a valve element cavity and a valve inner channel. The valve element is arranged in the valve element cavity. The air supply device communicates with the valve element cavity. The valve element cavity communicates with the vacuum pilot valve and the destroying pilot valve through the valve inner channel. According to the vacuumgenerator, the vacuum pressure meter with an energy-saving function can measure pressure of the vacuum pilot valve, after a pressure valve is compared with a preset pressure section, switching betweenthe connecting state and the disconnecting state of the vacuum pilot valve is carried out, thus the pressure in the vacuum cavity is kept within the set range, adsorbed objects are prevented from falling off, and consumption of positive pressure air is reduced greatly.

Description

technical field [0001] The invention relates to vacuum components, in particular to an integrated vacuum generator and its use method. Background technique [0002] 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 possible to use both positive and negative pressure in places where there is compressed air, or in a pneumatic system. It becomes very easy and convenient to obtain negative pressure anywhere. Vacuum generators are widely used in the fields of machinery, electronics, packaging, printing, plastics and robots in industrial automation. The traditional use of the vacuum generator is to cooperate with the suction cup to absorb and transport various materials, especially suitable for absorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects. In such applications, a common feature is that the vacuum flow rate is not hi...
