Application of EVP DLV series Liquid Ring Vacuum Pumps in Clay Industry
With the continuous development of the ceramics, sculpture, and clay product industries, the requirements for production efficiency and product quality are increasing. Vacuum degassing, as a core process in clay preparation, places higher demands on the performance, stability, and adaptability of vacuum equipment. EVP’ s DLV series double-stage liquid ring vacuum pumps, with their high vacuum levels, strong stability, excellent pollution resistance, and energy-saving features, are becoming the preferred equipment for an increasing number of clay product companies.
The following are specific applications of DLVdouble-stageliquid ring vacuum pumps in clay production:
1.Vacuum mud kneading (degassing) process
During the clay preparation process, the mixed clay contains a large amount of air bubbles and volatile gases. DLV double-stage liquid ring vacuum pumps create a high vacuum environment by evacuating the vacuum pug mill to completely remove the gas from the clay.
Pump function:
- Provide extremely high and stable vacuum environment to ensure thorough degassing.
- Eliminate bubbles and prevent defects such as cracking, deformation or pinholes in the product during the drying and sintering
- Improve the density and plasticity of the clay, making its structure uniform and facilitating subsequent throwing, extrusion or sculpture forming.
2.Continuous dehydration and homogenization process
While degassing, the vacuum environment helps to extract some of the free moisture in the clay and homogenize and knead the clay.
Pump function:
(1) Assist in reducing the moisture content of the clay, reducing drying shrinkage and energy consumption.
(2) Make the clay composition and hardness highly uniform, and improve the consistency and yield of the final product.
3.Centralized vacuum supply system
In large ceramic factories, multiple production lines may require a vacuum source simultaneously. DLV pumps can serve as the core of a centralized vacuum station, providing stable and reliable vacuum to multiple clay kneaders or molding stations.
Pump function:
- Reduce repeated investment in vacuum pumps and lower initial equipment costs.
- Through frequency conversion control and central management system, gas supply can be achieved on demand, significantly reducing overall energy consumption.
4.Adapt to harsh working conditions and ensure continuous production
Clay preparation is done in a humid environment, and small particles in the clay can enter the vacuum system along with the air. The DLV series pumps utilize a liquid ring principle and use water as the working medium, making them a natural fit for these conditions.
Pump function:
(1) No fear of water vapor and tiny particles, the liquid ring continuously flushes the pump cavity, effectively preventing blockage and wear.
(2) The sturdy structure supports 7*24 continuous high-intensity operation, ensuring the smooth execution of production plans.
(3) Significantly reduce downtime caused by equipment maintenance and improve overall production efficiency.
Core advantages of the DLV series in the clay industry
1.double-stagehigh vacuum, more thorough degassing
The DLV series adopts a double-stage series design, which can provide a vacuum degree far higher than that of a single-stage pump. This is crucial for removing micron-level bubbles and producing high-end ceramic products (such as electrical ceramics, special ceramics, and high-end daily-use ceramics). It can significantly improve the mechanical strength and yield rate of the product and is suitable for high-humidity and high-slurry environments without pump jams or blockages.
2.Excellent anti-pollution and anti-clogging capabilities
Its liquid ring seal principle gives it a natural advantage when pumping gases containing large amounts of water vapor and clay dust. The working fluid (water) continuously flushes the pump cavity, and particulate matter is discharged with the liquid, preventing the seizure or wear of precision components. This makes it particularly suitable for the harsh working conditions of clay preparation.
3.Stable operation, supporting unattended continuous operation
It adopts industrial-grade heavy-load design, and key components such as bearings and mechanical seals are reinforced, with low vibration and low noise during operation, which can fully match the 24-hour uninterrupted continuous production mode of the clay production line.
4. One machine for multiple uses, strong process adaptability
A single DLV vacuum pump can meet a wide range of needs, from small laboratory mud kneading machines to large-scale industrial centralized air supply systems, covering multiple process links such as vacuum mud kneading, dehydration, homogenization, etc., with a high return on investment.
5. Industry-proven, reliable
This series of products has a mature design and has been widely used in many fields such as ceramics, refractory materials, and sculpting clay at home and abroad. Its stability and durability have been widely recognized by the market.
Conclusion
The EVP DLV series Double-stage liquid ring vacuum pump, with its exceptional vacuum performance, excellent operating adaptability, and significant energy savings, has become a key piece of equipment for improving the quality and efficiency of clay preparation. Its two-stage design ensures thorough degassing, while its robust structure and liquid ring principle guarantee long-term stable operation in humid and dusty environments. It provides reliable equipment support for clay product companies to upgrade their products, reduce overall costs, and enhance their market competitiveness. When selecting equipment, it is recommended to precisely match it to the specifications of the clay kneading machine, the characteristics of the clay material, and the production cycle to maximize its performance.
