Circulation Type Vacuum Tank
Overview
Vacuum Tank is the updated equipment to apply in the soil improvement projects. The vacuum tank is mainly composite by pumping lines, water & gas separation tank, and the electrical control. This structure is designed in accordance with the soil improvement feature, to isolate the water and gas from the ground.
The difference between Vacuum Tank & Vacuum Pump as below picture shown:
Item | Vacuum Tank | Vacuum Pump |
Soil Consolidation Time | Shorten | Normal |
Automation System | Electrical System | Manpower |
Working Hours | Shorten | Normal |
Water & Gas Drainage Rate | High | Normal |
Equipment Arrangement in 10000m2 | 2 Sets/ 10000m2 | 7.5kW/10 Sets/ 10000m2 |

Operation Principle
The equipment include the Pumping Lines，Water & Air Separation Tank, Water Drainage Device and Electrical
Apparatus Control System.
1. To connect the Vacuum Pumping Units with the top of the Vacuum Tank;
2. To connect the pipeline which under the Geo-membrane with the Vacuum Tank, and Water Drainage Device;
3. To create the negative pressure under the Geo-membrane by Vacuum Pre-loading Lines, to absorb water to the Vacuum Tank and drainage out by the drainage device.
