Impregnation Tank

Product Specifications

Technical details and manufacturing context for Impregnation Tank

Definition

The impregnation tank is a sealed pressure vessel used as the primary chamber in a vacuum impregnation system. It is designed to hold porous materials such as castings, composites, or wood products during a process that removes air and moisture from their pores and then introduces an impregnating resin or sealant under pressure. This treatment enhances material properties like strength, sealing capability, or corrosion resistance. The tank is typically constructed from stainless steel (e.g., 304, 316L) or carbon steel, with design parameters that must be verified for each specific application. Key specifications include a design pressure range of 1.0–1.6 MPa (with special design required above 1.6 MPa per GB 150), a design temperature range of 50–150°C, and a vacuum degree of -0.098 to -0.08 MPa. Effective volume ranges from 0.5 to 50 m³, with inner diameters from 600 to 3000 mm and cylinder lengths from 1000 to 12000 mm. Heating power varies from 15 to 120 kW, and temperature control accuracy is ±2°C, while pressure control accuracy is ±0.01 MPa. The tank operates on a three-phase 380 V AC supply (±10%, 50/60 Hz). Shell material is typically Q345R (per GB 713), and sealing material is FKM, resistant to oils and solvents. Weight ranges from 1500 to 25000 kg, and overall dimensions vary by model, from 2000×1500×2000 mm to 15000×3000×3000 mm. These values are reference ranges; actual specifications must be confirmed with the manufacturer for the intended model and application. The tank is a critical component of a vacuum impregnation system, ensuring a sealed environment throughout the cycle for effective penetration and curing.

Working Principle

The impregnation tank operates by first creating a vacuum inside the sealed chamber, which draws air and moisture out of the material's pores. After reaching the desired vacuum level, impregnation fluid is introduced, often under pressure, forcing it into the evacuated pores. The tank maintains a sealed environment throughout the cycle to ensure effective penetration and curing. The process is controlled by parameters such as vacuum degree, pressure, and temperature, which are monitored and adjusted to achieve consistent results.

Frequently Asked Questions

What materials are used to construct impregnation tanks?

Impregnation tanks are typically made from stainless steel (e.g., 304, 316L) or carbon steel. The shell material is often Q345R, as per GB 713. The sealing material is usually FKM, which is resistant to oils and solvents. The choice of material depends on the application and the media being processed.

What are the typical design pressure and temperature ranges?

The design pressure typically ranges from 1.0 to 1.6 MPa, with special design required above 1.6 MPa per GB 150. The design temperature ranges from 50 to 150°C. These values are reference ranges and must be confirmed for the specific model and application.

How does the vacuum impregnation process work?

The tank is evacuated to create a vacuum, removing air and moisture from the material's pores. Then, impregnation fluid is introduced under pressure, forcing it into the pores. The sealed environment is maintained throughout the cycle to ensure effective penetration and curing.

What standards apply to impregnation tanks?

The design pressure and temperature are referenced against GB 150, and the shell material is specified per GB 713. These standards serve as procurement and verification references. It is essential to verify compliance with the manufacturer for the specific model.
