Jinan Liling MGW-001 High-frequency Reciprocating Friction and Wear Tester is newly launched, which accurately realizes the standardized detection of diesel lubrication performance.

Recently, Jinan Liling Testing Machine Co., Ltd. launched a self-developed MGW-001 high-frequency reciprocating friction and wear testing machine (diesel lubrication performance evaluation testing machine). The equipment fully meets the domestic and foreign mainstream oil testing standards and is equipped with self-developed electromagnetic drive core technology, which can provide high-precision diesel lubrication one-stop testing solutions for oil refining enterprises, quality inspection institutions and university research institutes, and fill the domestic demand for localization and upgrading of precision oil friction and wear testing equipment.
The MGW-001 testing machine launched this time is designed in strict compliance with SH/T0765-2005, ISO 12156.1-2016 and ASTM D6079. Its core is used for quantitative evaluation of diesel lubrication performance, and it is also compatible with testing of friction and wear performance of various lubricating oils and metal materials. It can realize multiple core testing functions of SRV testing machine, and it is suitable for scenes covering ex-factory quality inspection of oil products, research and development of friction characteristics of new materials, and compliance testing of third-party testing laboratories.
The equipment relies on the principle of electromagnetic reciprocating friction detection to complete the test: the standard steel ball specimen is driven by the self-developed patented electromagnetic driver, and the standard specimen fixed in the oil tank of the lower specimen is pressed with controllable load to realize the adjustable high-frequency reciprocating motion of 10 ~ 200 Hz, and the key data such as friction, oil film contact resistance and oil temperature are collected in real time throughout the whole process; The oil tank is equipped with a constant temperature heating module, and the temperature control range covers room temperature to 200℃, which completely matches the standard test condition of 60℃ specified by the national standard. The whole machine adopts a thickened steel damping base, which effectively suppresses vibration interference during the test and ensures the stability of the test data.
In the core hardware configuration, this model has four core advantages. First, the core drive unit is equipped with an electromagnetic vibration exciter patented by Jinan Liling, which has stable thrust control and no jitter, and is equipped with a precision push rod made of composite material, which has a high reciprocating straightness and a protective structure for sample disassembly, thus greatly reducing equipment loss; Secondly, the whole set of measurement and control system is independently developed based on MATLAB algorithm, and the whole Chinese visual operation software can monitor the full-dimensional parameters of reciprocating stroke, frequency, load and temperature in real time, automatically record the curve of friction coefficient and oil film thickness, and automatically stop after the test; Thirdly, it is equipped with a professional metallographic wear mark measuring system with a graduation accuracy of 1μm, which can directly collect and observe the wear marks of metal specimens. The software automatically measures the wear mark diameter and generates standardized test reports, which supports data storage, export and printing. Fourthly, the complete set of samples and consumables are modularized. The standard 6mm test steel ball and φ10×3mm test piece have been finely polished and screened, and the surface roughness and hardness indicators have reached international standards. The oil box comes standard with 2ml scale marks, which is convenient and efficient to operate.
The whole set of equipment adopts integrated complete configuration, including testing machine host, special constant temperature and humidity box, EVOC industrial computer, metallographic wear mark measuring system, ultrasonic cleaning machine, printer, complete set of standard samples and tool consumables. The exclusive constant temperature and humidity box independently controls the temperature and humidity, and the temperature stability range is 23 ~ 30℃ and the humidity is 40% ~ 70%, which is isolated from the interference of the test heat source of the main engine, so that the refrigeration system of the imported compressor runs stably and the energy consumption is lower; The matching ultrasonic cleaning machine can quickly clean the sample after the test, and the high and low lubricity standard reference oil is provided synchronously, and the standardized comparison test can be carried out after the equipment is unpacked.
According to the technical person in charge of the enterprise, the repeatability and reproducibility of the test data of MGW-001 testing machine fully meet the ASTM D6079 specification, and the error between the test results and the theoretical value of standard reference oil is controlled within 10%, which solves the pain points of traditional imported equipment, such as high procurement cost, long after-sales maintenance period and no localization adaptation of software. The operation threshold of the equipment is low, the whole process is automatically controlled, and there is no need for manual continuous duty, which greatly improves the detection efficiency of the oil testing laboratory. At present, it has been open to the national refineries, material research laboratories and third-party quality inspection institutions.
With the standardized development of domestic automotive diesel and biodiesel industries, the detection of oil lubrication performance has become a key link in the quality control of refined oil. The MGW-001 high-frequency reciprocating friction and wear testing machine launched by Jinan Liling this time, with domestic core technology, high-standard testing accuracy and complete sets, provides a cost-effective domestic alternative for the field of oil friction performance testing, and helps the independent upgrading of testing equipment in energy and materials industries.
