Basic dataStandard ID: JB/T 7857-2006 (JB/T7857-2006)Description (Translated English): Hydraulic fluid power. Valves. Method of evaluating contaminant sensitivity Sector / Industry: Mechanical & Machinery Industry Standard (Recommended) Classification of Chinese Standard: J20 Classification of International Standard: 23.100.30 Word Count Estimation: 11,169 Date of Issue: 2006-12-31 Date of Implementation: 2007-07-01 Older Standard (superseded by this standard): JB/T 7857-1995 Quoted Standard: GB/T 8104; GB/T 8105; GB/T 8106; GB/T 14039-2002; GB/T 17446; GB/T 18854; ISO 12103.1 Regulation (derived from): NDRC Notice No. 97 of 2006 Issuing agency(ies): Ministry of Industry and Information Technology Summary: This standard specifies the hydraulic valve pollution sensitivity evaluation method. The method chucking from contaminated, contamination wear/erosion of both the hydraulic valve to evaluate the solid particle contamination caused by change in performance. The purpose of the method is to compare the same test conditions for different types of hydraulic valves particulate contamination sensitivity. Since it is impossible for all on-site conditions that may occur are tested, and thus test results are not as a quantitative assessment of hydraulic valve polluted conditions in actual field performance basis. Through this evaluation method obtain different particle size and concentration on the hydraulic valve pollution pollution and contamination clamping wear/erosion effects, in order to determine the hydraulic valves required for the protection of the filtering requirements. This standard applies to the hydraulic fluid as the working medium of the various types of hydraulic valves.
