Xiangke LZY Road Brick Permeability Coefficent Tester Permeability Road Panel Testing Instrument

Xiangke LZY payment brick performance coefficient tester

1. Overview

The LZY pavement brick performance coefficient tester is suitable for testing the performance coefficient of suitable pavement bricks and suitable pavement panels in accordance with GB/T25993-2010 ^ ^ Appendix C Test Method for Suitable Pavement Bricks and Suitable Pavement Panels ^ ^ This instrument mainly consists of water tank, electrical control box, sample fixture, balance, and other parts The sample fixture is suitable for specifications with a cyclical cross section The fixture guarantees that liquid can only pass through the surface holes of the specifications during the test process and not leak from the edges of the specifications

2. Main technical parameters

1. Test pressure: 150mm water column,

2. Standard sample specification: Diameter: Φ 750-2mm, thickness 40-120mm,

3. Time: 0 to 99 hours,

4. Power supply voltage: 220V 50HZ,

2. Working principle

Permeability coefficient: The ability of a material to penerate through a liquid under a certain pressure difference

Under a certain pressure difference, let a fluid with a known dynamic visibility coefficient pass through the sample in a laminar flow state and measure the flow rate
