Shandong Hengmei Electronic Technology Co., Ltd. is committed to providing high-performance solutions for the industrial testing field. The HM-KR series emulsion resistance tester we have launched integrates advanced features such as high-precision temperature control, multi-channel parallel processing, and intelligent operation. It strictly follows international standards, has stable performance, and reliable data. This instrument has been widely used in multiple industries such as power, petrochemicals, shipping, and military.
Core technical principle: oil-water separation simulation under standardized conditions
The working principle of the emulsion resistance tester is based on international standards such as ASTM D1401, ISO 6614, etc. By precisely controlling the experimental conditions, the oil-water separation process is quantified
1. Emulsification preparation: Inject a certain volume of oil sample with distilled water (usually 40ml oil+40ml water) into a dedicated measuring cylinder and place it in a constant temperature bath.
2. Standard stirring: At a specific temperature (such as 54 ℃ or 82 ℃), the instrument uses a standardized stirring device (blade or paddle type) to stir at a speed of 1500 rpm for a certain period of time (such as 5 minutes) to fully emulsify the oil and water.
3. Static separation and observation: After stopping stirring, the instrument automatically starts timing. The operator or image sensor monitors the interface changes between the oil layer, water layer, and emulsion layer in real time, records the time required to separate a certain volume (such as 40ml) of water, or records the volume of residual emulsion after a certain time (such as 30 minutes).
Result interpretation: The shorter the separation time and the less residual emulsion, the better the anti emulsification performance of the oil. The core value of the emulsion resistance tester lies in its ability to provide highly reproducible and comparable quantitative data.
Technological advantages and innovative design
Modern anti emulsification testers have achieved high automation and intelligence, with significant technological advantages:
1. High precision temperature control system:
Technical implementation: By using an electric heating unit and a German A-level Pt100 high-precision temperature sensor, combined with PID algorithm, the temperature control accuracy of the constant temperature bath can reach ± 0.01 ℃.
Addressing pain points: Eliminating the impact of temperature fluctuations on emulsion formation and separation rates, ensuring the reproducibility of test results and comparability between different laboratories.
2. Multi channel parallel processing capability:
Technical implementation: Four experimental channel design, allowing for simultaneous testing of four samples.
Addressing pain points: Greatly improving detection efficiency, especially suitable for batch inspection of oil products or formula screening research and development, increasing work efficiency by 300%.
3. Fully automated and intelligent operation:
Technical implementation: Adopting a 7-inch industrial grade color touch screen, parameter settings are clear at a glance. The lifting mechanism adopts a precision slide table, and the sample grade conversion is driven by a stepper motor, with precise positioning and no need for manual intervention.
Addressing pain points: reducing the labor intensity and human error of operators, standardizing the testing process, and making the results more reliable.
4. High reliability and safety:
Technical implementation: The core control adopts high-performance MCU, which runs stably. Equipped with liquid level protection function, it automatically cuts off heating when the constant temperature liquid is below the safe liquid level to prevent dry burning.
Addressing pain points: Ensuring that the instrument can withstand the industrial environment requirements of long-term continuous operation and effectively extending the service life of the equipment.
Anti emulsification performance is one of the lifelines for measuring the quality of oil products. A high-performance emulsion resistance tester plays an irreplaceable role in oil research and development, production, procurement, and equipment status monitoring by providing accurate and reliable separation data. It is not only a laboratory equipment, but also a core decision-making tool for ensuring equipment safety, optimizing lubrication management, and controlling operating costs.
