Measurement of Oil Pressure Distribution between the Piston and Cylinder in Hydraulic Piston Pump

유압 피스톤 펌프의 피스톤과 실린더 사이에서의 압력측정

In this paper, an experiment was carried out to measure the hydrodynamic oil pressure distribution in the clearance gap between a piston and cylinder. The results showed that the pressure distributions are highly affected by the eccentricity of the piston. Therefore present experimental method can be used to enhance the performance of hydraulic piston pumps. Further experimental studies for various operating conditions and improvement in data acquisition methods are required to obtain more accurate results.
