These intelligent systems can adapt to variations in base oil viscosity and temperature, ensuring accurate and efficient blending and filling operations.

Lubricating Oil Automatic Quantitative Filling Technology

Automatic quantitative filling technology plays a crucial role in the final stage of the lubricating oil blending process. This technology ensures that the precisely formulated lubricant is dispensed into containers with exact and consistent volume.

The Significance of Precision

Inaccurate filling can have detrimental consequences. Overfilling containers leads to product waste and increased costs. Underfilling, on the other hand, compromises the effectiveness of the lubricant and can potentially damage machinery due to insufficient lubrication. Automatic quantitative filling technology eliminates these concerns by guaranteeing precise and consistent filling across every container.

Working Principle

The core of automatic quantitative filling technology lies in the utilization of high-precision metering devices. These devices can include:

• Flow Meters: These instruments measure the volumetric flow rate of the lubricant, ensuring the correct volume is dispensed into each container.
• Mass Flow Meters: By measuring the mass of the lubricant passing through the system, these meters provide an even more accurate filling solution, especially for lubricants with varying densities.
• Volumetric Positive Displacement Pumps: These pumps deliver a specific volume of lubricant with each cycle, guaranteeing consistent filling regardless of the lubricant’s viscosity.

These metering devices operate in conjunction with a control system that regulates the filling process. The control system receives pre-programmed data specifying the desired filling volume for each container size. Based on this information, the system controls the operation of the metering device and ensures the precise amount of lubricant is dispensed.
