1、 Instrument composition

The testing device consists of a vertical sand guide tube, a calibration funnel, a filter screen, a sample rack, and a sand collector.

IIWear resistance tester for raised road signsMain parameters

Sand guide pipe: can use an inner diameter not less than150mmComposed of solid plastic pipes with smooth inner walls, with a length of2850mmThe non perpendicularity of the sand guide pipe shall not exceed0.2°.

Calibration funnel: The upper opening size of the calibration funnel is120mm×40mm, height100mm, Four sided slope angles45The four sides of the upper mouth should be straight and sharp, ensuring that the sand falling on the edge of the mouth does not change direction when it falls into the bucket. The function of this funnel is to ensure that the sand directly falling into the mouth does not deviate from the ground and impacts the protruding road sign as vertically as possible, while the sand falling out of the mouth is deviated outside the bucket and cannot impact the protruding road sign. The calibration funnel should be able to move up and down, left and right, and forward and backward, making it easy to adjust the amount and uniformity of sand passing through the funnel.

Filter screen: The filter screen is located at the upper part of the sand guide pipe, with a mesh size greater than850MmThe standard network. The function of this filter is to establish the starting point of sand falling and to limit the flow rate of sand falling. The distance between the falling sand and the grid should not exceed30mm.

Sample rack: used to firmly clamp the tested sample, keeping the base surface of the sample perpendicular, and conveniently aligning the sample with the sand guide tube and calibration funnel. It can freely adjust the height of the tested sample so that its upper edge is not greater than the upper opening of the funnel150mmAnd it can adjust the horizontal direction to make the bottom edge of the sample's reverse reflection surface parallel to the long side of the funnel. The sample rack should not obstruct the free flow of falling sand.

Collector: one available300mm×500mmEnamel trays or other containers. Objective: To collect sand outside the calibration funnel.
