This invention discloses a continuous conductivity testing bench for lubricating grease and its testing method. The test bench includes a grease pump, a conductive base plate, a heating module, and an upper conductive plate. It can continuously measure the dynamic conductivity of the lubricating grease before and after breakdown and before and after blockage at a preset temperature, calculate the average conductivity during the continuous thickness change process, and conclude that the grease thickness is different when breakdown and blockage occur. It obtains the accurate values ​​of the grease thickness in the test area corresponding to each breakdown and blockage. In the blockage analysis, the volume of the grease to be injected into the test area is calculated by integration. Based on the instantaneous volume flow rate detected by the elliptical gear flow meter, the actual volume of the grease to be injected into the test area is calculated, and the flow rate of the grease pump is adjusted to ensure that the difference between the volume of the grease to be injected into the test area and the actual volume of the grease injected into the test area is within a preset range. This avoids the pressure changes caused by insufficient grease thickness or excessive grease affecting the test accuracy.
