Experimental Investigation on Friction Performance of O-ring Used in Compensatory Configuration of Mechanical Seal

Experimental results of O-ring frictional force under dry friction and water lubrication were obtained using INSTRON,based on knowing the principle of dry friction and water lubrication.The relationship of frictional coefficient with load and sliding speed was analyzed.The results indicated that water film could be developed between contacting surfaces under water lubrication,which led to less frictional force and stability of performance.
