Abstract: Aiming at the accuracy of the slurry ratio in the singlesealed test environment of the hub bearing, the experimental research on the slurry particle deposition amount in the slurry input pipe of the hub bearing single seal test machine was carried out.The measurement method of slurry particle deposition amount in the slurry input pipeline of the test machine slurry conveying system was proposed. The slurry flow in the pipeline of the test machine slurry conveying system and the slurry particle deposition amount in the slurry input pipeline under different flow rates were measured. The method obtained the relationship between the amount of slurry deposited and the flow rate.The results show that with the increase of slurry flow, the sediment concentration of slurry particles in the slurry input pipeline generally decreases. When the slurry flow reaches a certain amount, the decreasing trend becomes slower.Finally, the minimum slurry flow rate of the test machine with the accuracy of ensuring the matching ratio of the single bearing seal test mud of the hub bearing is 425.8 ml/s.
