In industrial lubrication systems such as turbines, compressors, and hydraulic equipment, lubricants may become contaminated with water during operation. Oils with poor water separation ability may form stable emulsions, which can cause lubrication failure, corrosion, oxidation, and reduced equipment reliability. Therefore, evaluating the oil-water separation performance is an important part of lubricant quality control.

This automatic analyzer integrates microprocessor control, intelligent temperature regulation, automated stirring, and digital data management, providing stable and repeatable testing conditions for modern petroleum laboratories. The instrument features a touchscreen interface, automatic timing, automatic lifting stirring mechanism, and multi-sample testing capability, significantly improving testing efficiency and reducing operator workload.

The analyzer is widely used in petroleum refineries, lubricant production facilities, power generation plants, chemical laboratories, railway maintenance departments, and scientific research institutions.

The Automatic Oil Demulsibility Analyzer is used to evaluate the water separability of petroleum oils and synthetic lubricants in laboratory environments.

• Turbine oils
• Hydraulic oils
• Circulating oils
• Industrial lubricants
• Synthetic lubricants
• In-service turbine oils

Typical application environments include:

• Petroleum refining laboratories
• Lubricant manufacturing plants
• Power generation and turbine maintenance facilities
• Chemical industry laboratories
• Railway equipment maintenance departments
• Oil analysis and quality control laboratories
• Research institutions

The instrument adopts a color touchscreen interface with Chinese and English language options, allowing operators to easily input preset parameters such as temperature and test duration through guided menus.

The system is controlled by an STM microprocessor with adaptive PID temperature control algorithm, automatically adjusting the heating curve to meet standard testing requirements.

The instrument provides highly stable temperature regulation with an accuracy of ±0.01°C, ensuring precise and repeatable demulsibility testing conditions.

The analyzer performs automatic stirring and automatic timing, while the stirring motor arm automatically lifts and lowers the test tubes, greatly reducing manual operation.

The system supports four test positions, enabling simultaneous analysis of multiple samples and significantly improving laboratory productivity.

When the test time is completed, the instrument automatically triggers an alarm. Up to 500 test results can be stored, allowing convenient historical data review.

The mechanical transmission system operates smoothly with minimal noise, ensuring long-term stable performance.

Critical internal components including heating elements and stirring parts are made of corrosion-resistant stainless steel, ensuring durability and reliability.

Optional configuration allows adjustable stirring speeds from 300 r/min to 2000 r/min, providing flexible testing capability for different applications.

The instrument supports multiple language display options, and the internal software can be upgraded when testing standards are updated.

This Automatic Oil Water Separability Analyzer is designed and manufactured in accordance with the following testing standards:

• ASTM D1401 – Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids
• GB/T 7305 – Petroleum and Synthetic Fluids — Determination of Demulsibility Characteristics
• GB/T 7605 – Determination of Demulsibility of Turbine Oils in Service

These standards are widely applied in petroleum laboratories and lubricant testing facilities for evaluating the water separation performance of lubricating oils.
