High-pressure and high-speed gas enters the ejector tube assembly through the air inlet pipe assembly (high vacuum is generated by the air bag in the ejector tube assembly), which is to generate high vacuum in the tank body and absorb materials.

1. Yellow is the flow direction of compressed gas, red is the flow direction of gas in the tank, and orange arrow is thedirection of material entry;

2. The gas flows through the inlet pipe into the air distribution bag, and the air distribution bag generates vacuum (when the restricted flow passes through the reduced flow section, the flow rate of the fluid increases, and the flow rate is inversely proportional to the flow section. The increase of the flow rate is accompanied by the decrease of the fluid pressure, and the low pressure will be generated when the fluid is close to the high speed flow, resulting in adsorption)

3. When the low pressure is generated at the suction port of the air bag, the air in the tank flows to the air distribution bag and flows out with the compressed gas, that is, the vacuum is generated in the tank;

4. The internal pressure of the tank is lower than the external pressure, and the material will enter the tank under the action of atmospheric pressure (the suction height of clean water is 6-9 meters, and the specific gravity and viscosity of the material vary with the delivery distance)
