  • Visualization Measurement of Rotational Motion of Pistons and Slippers of A Piston Pump (Preliminary Experiment)

説明

Hydraulic piston pumps are used in fluid power systems such as manufacturing machinery and construction machinery, which require long life and high efficiency. There is a need to reduce friction loss and to prevent seizure of the sliding parts. To overcome these problems, it is necessary to comprehend the motion and characteristics of the tribological parts in the pumps. This study aims to clarify the movement of the pistons and slippers under actual operating conditions by means of the visualization method. The test pump with the transparent windows was manufactured and the pistons and slippers were marked with ink. Under a specific operating condition, images were recorded with a high-speed camera, the rotational speed of the pistons and slippers was measured, and the ratios of the speed were examined. As a result, the possibility to observe the rotation of pistons and slippers by visualization was shown and the variation of the rotational speeds was obtained.
