Screw Pump Repair & Troubleshooting. Get A Free Quote. The screw pump is a more complicated type of rotary pump. The screw pump has two screws with opposing threads; one screw turns clockwise, and the other counterclockwise. The turning of the screws, and consequently the shafts to which they are mounted, draws the fluid through the screw pump.
Tunnel Boring Machines (TBMs) have revolutionized the way tunnels are constructed, making the process faster, more efficient, and less disruptive to the surrounding environment. One crucial component of TBM operations is the desanding plant, which plays a vital role in removing solids from the slurry that is used to support the tunnel face during excavation. In Portugal, TBM desanding plants are essential for ensuring the smooth operation of tunneling projects across the country.

Understanding TBM Desanding
TBM desanding involves the separation of solids from the slurry that is used to stabilize the tunnel face during excavation. As the TBM advances, it excavates soil and conveys the excavated material out of the tunnel. In slurry-supported tunneling, the bentonite suspension supports the tunnel face, preventing collapses and maintaining stability.
However, as the slurry is circulated back to the surface, it carries with it a significant amount of solids, including sand, gravel, and other debris. These solids need to be removed to prevent clogging of the system and ensure the efficient operation of the TBM. This is where the desanding plant comes in.
Importance of TBM Desanding Plant
A TBM desanding plant is a specialized facility that is designed to separate solids from the slurry, allowing the clean slurry to be recirculated back into the tunneling operation. Without an effective desanding plant, the TBM's performance can be severely impacted, leading to delays, increased wear and tear on equipment, and higher operating costs.
In Portugal, where tunneling projects are on the rise, the need for reliable and efficient desanding plants is more critical than ever. With the country investing in infrastructure development and underground transportation systems, the demand for TBMs and associated equipment, such as desanding plants, is expected to increase in the coming years.
TBM Desanding Plant in Portugal
Portugal boasts a growing market for TBM desanding plants, with both domestic manufacturers and international suppliers catering to the needs of tunneling projects across the country. These plants are equipped with advanced technology and efficient processes to ensure the effective separation of solids from the slurry, allowing for continuous and uninterrupted tunneling operations.
The TBM desanding plants in Portugal are designed to handle varying volumes of slurry and solids, depending on the specific requirements of the project. They are equipped with screens, hydrocyclones, and other separation mechanisms to efficiently remove solids of different sizes from the slurry, ensuring that only clean fluid is returned to the TBM for further excavation.
Advantages of TBM Desanding Plant
The use of a TBM desanding plant offers several advantages to tunneling projects in Portugal. Some of the key benefits include:
1. **Improved Efficiency**: By removing solids from the slurry, the desanding plant helps maintain the TBM's performance and efficiency, reducing downtime and increasing productivity.
2. **Cost Savings**: Effective desanding can lead to cost savings by preventing equipment failures, reducing maintenance costs, and optimizing the use of resources.
3. **Environmental Protection**: By ensuring that only clean slurry is discharged back into the environment, desanding plants help minimize the impact of tunneling operations on the surrounding ecosystem.
4. **Enhanced Safety**: Clean slurry reduces the risk of blockages and other operational issues, promoting a safer working environment for tunneling crews.
Future of TBM Desanding in Portugal
As Portugal continues to invest in infrastructure development and urban planning, the demand for TBM desanding plants is expected to grow. With advancements in technology and a focus on sustainability, the future of desanding plants in the country looks promising.
