LZY Brick Permeability Coefficient Apparatus

summarize

LZY road brick permeability coefficient tester is suitable for the test method of determining the permeability coefficient of permeable road brick and permeable road slab according to GB/T25993-2010 Appendix C Test Method for Permeable Road Brick and permeable road slab. The instrument is mainly composed of water tank, electrical control box, sample fixture and sky level. The fixture is suitable for specimens with a cylindrical cross-section. The fixture ensures that the liquid can only pass through the surface of the specimen during the test without leaking from the edge of the specimen.

The working principle

Permeability coefficient: the ability of the material to penetrate through the liquid under the action of a certain pressure difference.

Under a certain pressure difference, the fluid with known dynamic viscosity coefficient passes through the sample in laminar flow state, and the flow rate is measured.

Permeability coefficient test device is shown in Figure 1:

1– water supply system;

2– overflow port;

3– Overflow tank: with a drain and maintain a certain water level of the tank;

4– support;

5– проба;

6– measuring cylinder;

7– water level difference;

8– Permeable cylinder: a cylinder with overflow mouth and can maintain a certain water level.
