The fully automatic lubricating oil evaporation loss tester is mainly applied in three core scenarios: lubricating oil production quality control, scientific research and development, and third-party testing. By replacing manual operations, it improves testing efficiency and data accuracy, and serves as a key piece of equipment for standardized testing in the modern lubricating oil industry.

I. Core Application Scenarios: Covering the Entire Industry Chain

The application of the fully automatic tester runs through the entire process of lubricating oil from R&D to end-use, focusing on the following three fields:

1. Lubricating Oil Production Enterprises (Quality Control Link)

• Incoming Raw Material Inspection: Conduct evaporation loss screening on raw materials such as base oils and additives to prevent substandard finished product performance caused by unqualified raw materials.

• Finished Product Factory Inspection: Batch-test the evaporation loss of finished lubricating oils (e.g., internal combustion engine oils, hydraulic oils) to ensure each batch of products meets national standards or enterprise internal control standards.

• Production Process Monitoring: Real-time monitor changes in the evaporation characteristics of oil products during the production process, adjust formulas or process parameters in a timely manner, and reduce the generation of unqualified products.

2. Scientific Research and Formula Development Institutions

• New Oil Product R&D: Quickly compare evaporation loss data of different base oil and additive combinations to accelerate the formula iteration of high-stability lubricating oils (e.g., long-life engine oils).

• Working Condition Simulation Testing: Use the adjustable temperature and time parameters of the equipment to simulate evaporation under different application scenarios (e.g., high-temperature engines, low-temperature refrigeration systems) and evaluate oil product adaptability.

3. Third-Party Testing and Supervision Institutions

• Product Compliance Certification: Provide enterprises with legally effective test reports to facilitate product market access.

• Market Quality Supervision: Entrusted by regulatory authorities, conduct sampling tests on lubricating oil products in the circulation field, crack down on unqualified products, and maintain market order.

Applicable Standards

• NB/SH/T0059-2010 Standard Test Method for Evaporation Loss of Lubricating Oils (Noack Method) — Method B

• ASTM D5800

Main Performance Features

1. The heating system of the instrument has obtained a utility model patent (Patent No.: ZL201621446810.0).

2. The pressure stabilization system of the instrument has obtained a utility model patent (Patent No.: ZL201621460301.3), ensuring stable pressure.

3. The control system of the instrument adopts an advanced PLC (Programmable Logic Controller) as the control core. Compared with similar instruments using a single-chip microcomputer as the core, it has significant advantages in terms of stability and accuracy.

4. The instrument is equipped with a 7-inch full-color, high-performance, high-definition TFT LCD touchscreen with highly sensitive touch response. All operations and data displays of the instrument can be realized on this touchscreen, and the touchscreen layout adopts a humanized design, making all functions clear at a glance.

5. The exterior of the instrument adopts a desktop integrated structure, requiring minimal placement space. The unique design of the control box on the right side, the differential pressure gauge on the rear side, and the heating bath forms a semi-enclosed space, which effectively blocks air flow around the crucible and enables more accurate and stable temperature control of the sample.

6. The automatic test system of the instrument integrates all operations required for the test, including heating, timing, constant pressure value maintenance, test result storage, and printing. With a single button press, the entire test process can be completed automatically.

7. The instrument is equipped with imported accessories such as a French imported inclined-tube differential pressure gauge and a Japanese SMC air filter.

8. The instrument is equipped with a specially customized micro-vacuum pump with advanced performance and stable negative pressure.

9. The instrument has high temperature control accuracy for samples. During the test, the pressure difference is automatically adjusted to keep it within the range of 20 mm ± 0.2 mm high mercury column.
