In today’s industrial environment, the reliability and stability of lubricating oils directly influence the performance and durability of mechanical systems. As engines and machines continue to operate under increasing thermal stress, understanding how lubricants behave under high temperatures becomes essential. One of the most crucial parameters in this regard is the evaporation loss, which affects oil longevity, engine cleanliness, and overall maintenance costs. The Lubricating Oil Evaporation Loss Tester, developed and supplied by Shijiazhuang Faith Machinery Co., Ltd., provides an essential solution for accurately determining the evaporation characteristics of lubricants under controlled thermal conditions.
Lubricating oil, when exposed to elevated temperatures in engines or gear systems, undergoes gradual degradation. Part of this degradation process is the loss of volatile components through evaporation. When these volatiles escape, the remaining oil becomes thicker and less effective in forming a protective lubricating film. This can lead to increased friction, higher operating temperatures, and accelerated wear of engine components.
Accurate measurement of this evaporation loss helps manufacturers, quality control laboratories, and researchers in developing lubricants that offer longer service intervals and improved thermal stability. The data obtained also aids in compliance with international standards such as ASTM D5800 or DIN 51581, which govern lubricant volatility testing procedures.
The Lubricating Oil Evaporation Loss Tester functions by exposing a measured quantity of oil to a regulated air flow at a specific elevated temperature for a predetermined time. This simulates real-world high-temperature operating conditions.
The key elements of the testing process include:
Precise thermal control, usually around 250°C, to mimic the temperatures encountered in an operating engine.
Air flow regulation, ensuring a constant and standard volume of air passes over the oil surface.
Weight measurement, before and after the test, to determine the percentage of oil lost due to evaporation.
The resulting data reflects the oil’s volatility and is particularly valuable in comparing formulations or validating production batches.
At Shijiazhuang Faith Machinery Co., Ltd., the Lubricating Oil Evaporation Loss Tester is designed for both efficiency and precision. The system includes:
High-accuracy heating blocks or baths with real-time temperature feedback.
A calibrated air delivery system to maintain uniform testing conditions.
Durable test chambers that support long-term usage without chemical degradation.
Integrated timing and weighing systems that simplify data collection and minimize operator errors.
In addition, the instrument is engineered to be user-friendly, allowing laboratory technicians to execute tests with minimal training. Its modular design enables easy cleaning and maintenance, improving operational uptime.
This testing equipment serves a broad array of sectors:
Automotive: Evaluating the thermal resistance of engine oils, transmission fluids, and greases.
Aerospace: Ensuring turbine oils maintain performance in extreme temperature conditions.
Industrial machinery: Monitoring and comparing lubricants used in compressors, hydraulics, and heavy-duty gear systems.
R&D laboratories: Developing new oil formulations that meet tightening environmental and performance standards.
By incorporating evaporation loss testing as a standard quality check, organizations enhance their product consistency, reduce warranty claims, and improve customer satisfaction.
As emission regulations tighten and synthetic lubricants become more prevalent, controlling volatility becomes increasingly important. Formulators are now experimenting with base oils and additive packages designed to minimize evaporative losses. The role of evaporation testing will expand further into hybrid and electric vehicles where gear oils and thermal fluids are subjected to new operational demands.
Shijiazhuang Faith Machinery Co., Ltd. remains committed to supporting its partners in the lubricant industry by providing advanced, dependable testing instruments that meet the demands of modern applications.
