Introduction: The test machine is designed in accordance with the technical indicators required by the industry standard SH/T0765-2005 "Diesel Lubrication Evaluation Method (High Frequency Reciprocating Tester Method)" (ISO12156-1:1997, MOD Standard Method) and the technical specifications are in accordance with Standard SH/T0765-2005 diesel lubrication evaluation method (high-frequency reciprocating testing machine) requirements, can meet the test requirements for assessing diesel lubricity, can be widely used in oil refineries, quality inspection agencies, research institutes and other units of diesel lubrication Sexuality assessment can also be used for the detection of lubricating properties of other oils or materials (with some of the functions of the SRV tester) MGW-001 high-frequency reciprocating friction and wear testing machine, the basic principle is the use of an electromagnetic drive, when a movement When the test piece is pressed against a fixed test piece, a smaller displacement reciprocates. The moving test piece, the reciprocating displacement and frequency, and the load are all adjustable. The device can measure the friction between the two test pieces. Force and electrical contact energy, the underlying fixed test piece is placed in a small sump equipped with a test lubricant and can be heated. Features: 1 Electromagnetic actuators (excitation shakers) with independent intellectual property rights and national invention patents, energy saving, stability, and high control accuracy (thrust controllability, no jitter); 2The push rod design adopts composite materials and customized guide rails. It has no lateral interference, high straightness of reciprocating displacement, stable displacement, high precision, and good repeatability of experiments. Push rod design card protection device to avoid damage to the exciter when disassembling the sample. 3 The test oil box is engraved with a 2ml oil scale to facilitate the addition of oil. 4 The design of the steel ball chuck is fully considered for ease of disassembly. 5 The heater adopts PTC chip ceramic heater, which is uniform in heating, safe in use, long in service life, and does not need to be replaced; 6 The entire system is mounted on a steel base that reduces any excess vibration in the mechanical structure. 7 Oil film resistance can be measured by both AC and DC measurement methods to facilitate selection; 8 Main functions of computer control software: All parameters of the experimental process are monitored throughout the entire process, data sampling cycles are stored, and the operating interface is full of Chinese culture.
