Development of Temperature-controlled and Humidity-controlled three-body Abrasive Wear Testing Machine based on MLD-10 Dynamic Abrasive Wear Testing Machine

摘要

In order to simulate engineering machinery (such as mining machinery,feed pellet machine,building machinery and so on),which existence of different degrees of high temperature and humid corrosion three-body abrasive wear behavior in the laboratory environment.In view of the current three-body abrasive wear testing machine cannot simultaneously take into account the composite conditions characteristics of the three-body abrasive wear behaviour,high temperature and humidity,and make the optimization design,based on the MLD-10 dynamic abrasive wear tester.It includes corrosion and wear groove,fluid medium,temperature measuring and controlling device,stirring device,etc.A three-body abrasive wear testing Machine that can control temperature and humidity.Subsequently,the simulated working condition test of the ring die of feed pellet machine were carried out.The test results show that the wear appearance of the test sample is basically consistent with that of the real ring die of feed pellet machine.It indicates that the developed testing machine can simulate the high temperature and humid three-body abrasive wear behavior,and has good reliability and applicability.
