Summary: This standard specifies test methods for measuring the flow of hydraulic transmission filter anti- fatigue properties. By adding a specific pollutant particles to test the system, so that the filter reaches a predetermined maximum pressure, and to consistently filter in under the alternating flow for anti- fatigue tests. This standard establishes a unified approach. For determining the filter element against the pressure fluctuations caused by the alternating flow and cause damage capability.

Foreword

This standard is identical with ISO 3724.2007 "Hydraulic filters use particle pollutants measured resistance to flow fatigue" (English Chinese Version). This standard is equivalent translation ISO 3724.2007. For ease of use, this standard does the following editorial changes. --- "2 Normative references" chapter, instead of the corresponding national standards with international standards; --- Delete ISO 3724.2007 Annex A and references. This standard is GB/T 17488-1998 "hydraulic filter verification of flow fatigue characteristics," the amendment. This standard replaces GB/T 17488-1998. This standard compared with GB/T 17488-1998, has the following changes. --- Change the standard name; --- Increase pollutants addition method; --- Of filter pressure - time waveform make provisions; --- On the viscosity of the test liquid make provisions; --- Removal of the test liquid temperature range specified; --- Flow pulsation frequency of the test to make more precise provision. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of hydraulic and pneumatic (SAC/TC3) centralized. This standard is drafted by. China Shipbuilding Industry Corporation seventh Research Institute of Jiujiang ○ seven divisions. Participated in the drafting of this standard.

Introduction

In the hydraulic drive system, the power is by pressure fluid in a closed loop to transfer and control. This is both a liquid lubricant and The power transfer medium. Filter to maintain clean fluid filtered through the insoluble contaminants. From the actual filter is in the filtering process Effect of porous devices. In addition to the efficiency of removal of contaminants the filter depends on its design itself, but also depends on its sensitivity to unstable operating conditions, such Unstable operating conditions often cause fatigue and damage filter. GB/T 17488-2008/ISO 3724.2007 Determination of particulate contamination of hydraulic filters use Resistance to flow fatigue

1 Scope

This standard specifies the test method for determining hydraulic transmission filter resistance to flow fatigue characteristics. By adding a specific particle pollution to the test system Pollutants, so that the filter reaches a predetermined maximum pressure, and the filter in a consistent alternating flow fatigue tests carried out. This standard establishes a uniform method for determining the filter against the flow fluctuations caused by changes in the pressure is alternately damage caused ability.
