Foreword

Appendix A of this standard is a normative appendix. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee tractor (SAC/TC140) centralized. This standard was drafted. National Tractor Quality Supervision and Inspection Center. Drafters of this standard. Liu Hui, Liu Hua, Xie Zhi bridge, Liu Lingwen. Tractors anti-water leakage test methods

1 Scope

This standard specifies the tractor anti-water tightness test methods. This standard applies to floods, droughts and dual-use guide wheel radius or minimum static ground clearance ≤500mm wheeled tractors and tractor Crawler Tractors anti-water tightness test, Ship tractors and paddy field operations can be implemented by reference.

2 Test Equipment

In the facility can choose one of the following. a) an annular mud sink width should meet the operational requirements of 3.3 tests, mud tank depth adjustable. Mud clay content of about 25% (Mass percentage); Length and width b) mud pool can accommodate the entire tractor, mud pool depth adjustable. About 25% of clay mud content (percent by mass Division ratio). Stir in the mud pool mud mixing and loading of the tractor should have the means.

3 Test Method

3.1 The test shall be the date of shipment from the tractor does not exceed six months, and the working time is not more than 150h (including running, test time) love Carried out under conditions. 3.2 Tractor test in the mud duration of 2h. 3.3 When the annular slurry tank tested by the tractor driver's steering or traction device traction. To impose its rated towing tractor 30% of the power load, wheeled tractor close to 6km/h speed driving cycle; tractor close to 4km/h speed loop Driving. When wheeled tractor test, the water in line with the guide wheel center line, but when the guide wheel static radius greater than 400mm, adjust the water, So that each of the wheels with a draft of 400mm; when the tractor test, the water is consistent with the drive wheel axis. 3.4 when tested in the mud pool, the tractor should work at the state level, to impose its calibration tractor traction load of 30% The line speed for the Netherlands, each wheel tractor shall comply with the provisions of 3.3. When wheeled tractor test, the water in line with the guide wheel center line, but When static wheel radius greater than 400mm guide, adjust the water so that all the wheels with a draft of 400mm; when the tractor test, the water and flooding Fixed axle center line of the same. After 3.5 prototype test at dry place to stand more than 12h, allowed to percolate until external no residual traces of water, oil spills inspection and dismantling rounds Axis, carried into the mud examination steering oil seal section. 3.6 pairs of lubricating oil, grease and electric iron by visual exploration methods water testing. When the probe electric iron, electric iron should be fully preheated, to be After the first electric iron oiled surface fumes before use.

4 determine the test results

4.1 parts of a test by test seepage, leakage is determined that the oil spill. 4.2 Seal the inside edge and lubricants, grease seal cavity oil, tallow visible water droplets or electric iron exploration has crackle judged to feed Muddy water.

5 Test Report

Tractors anti-water tightness test should complete test report, test report format in Appendix A. ......
