I will introduce the working principle of the straight empty stone sucker. When the compressed air enters the straight air blower from the supply port, it will produce an acceleration effect when passing through the narrow internal mouth, so as to flow through the diffusion chamber at a faster speed, and drive the air in the diffusion chamber to flow out quickly together when accelerating through the diffusion chamber. As the air in the diffusion chamber flows out quickly along with the compressed air, instantaneous vacuum effect is produced in the diffusion chamber. When the vacuum pipeline is connected to the vacuum inlet, the vacuum generator can extract vacuum for the vacuum pipeline.

Suction cups are basically made of rubber. With a rubber material were the main reasons for rubber product is more dense mesh soft attributes of the mesh also has the characteristics of good restore elastic deformation in order to reuse, it is used on the surface of the object that chuck and absorb the essential conditions of forming the sealing between, if use hard material to make the suction cups, There is no way to seal through the soft deformation, and the air has to be sucked back through the gap between the sucker and the stone sucker on the surface of the object. The air in the diffusion chamber flows out of the diffusion chamber together with the compressed air and flows through the diffuser. As the air circulation space gradually increases, the air pressure out of the exhaust port decreases rapidly and melts into the ambient air. At the same time, when the dry accelerated air exits the exhaust valve, it generally produces a loud sound, so it is usually equipped with a muffler in the exhaust valve of the straight air generator to reduce the exhaust noise of compressed air. The working principle of the straight air stone sucker is analyzed and compared for your reference
