| Abstract | The object of this study is to verify the restriction parameter and displacement coefficient of cylindrical spool-type restrictors. Using homemade open-type hydrostatic slideways to measure the inlet supply pressure, the out pressure, and the lubricant flow. Using the simultaneous linear regression equation obtains the restrictors of the restriction parameter, displacement coefficient. Among four test restrictors, design peripheral gap is different. Under three supply pressure, measured data of restrictors had measured. Measurement data was incorporated into the flow balance equation with linear regression least square error method to analyze the restriction parameter of restrictors. Under the supply pressure, referring to the Identification flow and displacement coefficient can obtain that the bearing load influence spring to the regulatory role of the out pressure and flow. Experimental results showed the peripheral gap affect the flow. The restriction parameter of restrictors is increased by increasing supply pressure and displacement coefficient trend down. The average flow error of restrictors between the identification and experiment was less than 5%, The restrictor with 5 kg /cm^2 supply pressure trend better, and the conclusion is the same as the theory of flow regulation. Furthermore, to improve the structure and built-in spring of restrictors finds the best restriction performance. |
