Thestaticanddynamicfrictioncoeficientsandtheirdiferencesare importantindicatorsforevaluating theanti-stick-slip performance of guideway oils,which provide significant reference for judging the lubrication stability，anti-crawling performance and practical applicability of guideway oils under low-speed and heavy-load working conditions.

Lubricant Stick-Slip Characteristic Tester

FDH-9101

Functional Features

Adopts anautomatic loading mechanism to apply test force with high accuracy and stability.

·Equipped with a computer control system and touch-screen operation interface based on Windows operating system,which can display real-time variation curves of dynamic and static friction coefficients aswell as their differences.

Adopts guideway positioning and servo motor driving mode with high displacement control precision and stable operation.

Uses a spring force-measuring structure combined with a high-precision friction force sensor to measure friction force in real time and automatically calculate dynamic and static friction coefficients.

Both upper and lower friction pairs are made of Grade l cast iron with scraped contact surfaces. The dimensions and scraping requirements comply with standard specifications, featuring excellent wear resistance.

·The computer automatically completesdata acquisition, processing and result output, and supports test data storage and printing to facilitate analysis, traceabilityand presentation of test results.

Petroleum Products Carbon Residue Test

Scope of Application

This instrument is designed and manufactured in accordance with the requirements of GB/T17144,ISO10370 and ASTM D4530 standards.Itis suitable for the determination of carbon residueof petroleum products by the micro method.Under nitrogen protection,the sample is subjected to programmed heating and high-temperature pyrolysis, soas toevaluate the tendencyofpetroleum products to formcarbonaceous residuesandrelative coking performance under specified conditions.

Automatic Micro Carbon Residue Tester

FDR-1902

Functional Features

· Adopts a touch LCD display and programmed temperature control system,which can display temperature curves and operating status inreal time during the test, featuring simple and intuitive operation.

·Automatically switches nitrogen flow rate according to standard procedures to reduce manual intervention during testing and improve the consistency of the testing process.

· Equipped with a software control system supporting test data recording, result calculation, historical data storage and query functions.

· Provided with a safety protection program; the instrument can automatically stop the test in case of over-temperature or excessively low nitrogen flow rate during operation， improving operational safety.

Equipped with a condensation/waste liquid collection device，and waste gas can be connected to the laboratory exhaust system to reduce the impact of test emissions on the laboratory environment.

·Different specifications of sample tubes and sample racks can be configured in accordance with standard requirements to meet different sample volume and testing needs.
