Product Details
1、 Overview
The LZY pavement brick permeability coefficient tester is suitable for testing the permeability coefficient of permeable pavement bricks and permeable pavement panels in accordance with GB/T25993-2010 "Appendix C Test Method for Permeable Pavement Bricks and Permeable Pavement Panels". This instrument mainly consists of water tank, electrical control box, sample fixture, balance, and other parts. The sample fixture is suitable for specimens with a cylindrical cross-section. The fixture ensures that liquid can only pass through the surface holes of the specimen during the test process and not leak from the edges of the specimen.
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 penetrate through a liquid under a certain pressure difference.
Under a certain pressure difference, let a fluid with a known dynamic viscosity coefficient pass through the sample in a laminar flow state and measure the flow rate.
