The Engine Oil Boundary Pumping Temperature Meter is a specialized analytical instrument designed and manufactured in strict accordance with GB/T 9171 (Chinese national standard) and ASTM D3829 (international test method). It is primarily used for determining the yield stress and apparent viscosity of engine oils under low-temperature boundary pumping conditions — critical performance indicators that directly affect engine startup reliability in cold environments.
The instrument adopts a fully automatic temperature control system and supports PC-based operation. Users can monitor, configure, and execute tests through an intuitive human-computer interaction interface, which significantly reduces manual intervention and improves testing efficiency. The built-in new-generation intelligent control system enhances overall stability and repeatability, achieving more precise temperature regulation and higher calculation accuracy. The overall technical level of this analyzer is recognized as leading in the domestic petroleum testing industry.
1. Efficient and environmentally friendly refrigeration system
The instrument adopts a compressor refrigeration method, which provides faster cooling rates compared to traditional semiconductor or liquid nitrogen methods. It operates with low noise and reduced energy consumption. The heating module uses a stainless steel heating rod, offering high thermal efficiency, oxidation resistance, and long service life — ensuring both safety and reliability.
2. High-precision temperature control and intelligent automation
A microcontroller-based control system manages the entire temperature regulation process automatically. The system supports precise temperature stepping and stable holding, significantly improving the stability and reliability of the analyzer. This design minimizes temperature overshoot and fluctuation, leading to higher calculation accuracy for viscosity and yield stress values.
3. Built-in monitoring and durable mechanical design
An internal precision program continuously monitors temperature, test cycle, and rotor movement in real time. The rotor is made of a high-strength alloy, which is lightweight, resistant to deformation, and easy to clean. The cone tip is designed to resist damage during normal use and cleaning, extending the operational life of the consumable parts.
4. User-friendly operation and low maintenance
The system is designed for minimal daily maintenance. The alloy rotor and sample cell are easy to disassemble and clean. The software interface provides real-time curve display, data logging, and report generation, making it suitable for both research laboratories and quality control environments.
