Product description
Parameters
The rock free expansion tester is suitable for determining the swelling properties of rocks containing easily absorbent expansive minerals in the natural state, such as clay rocks. The test is the ratio of the radial and axial deformation of the specimen to the diameter and height of the specimen after immersion in water, respectively, expressed as a percentage.
Compliance with standard specifications:
GBT 50266-2013 Standard for Test Methods for Engineering Rock Mass;
JTG E41-2005 Highway Engineering Rock Test Regulations;
SL 264-2001 Water conservancy and hydropower engineering rock test regulations;
DLT 5368-2007 Rock Test Regulations for Hydropower and Water Conservancy Projects;
TB 10115-2014 Railway Engineering Rock Test Regulations.
Main technical parameters:
1. Dial gauge range: 0-3mm accuracy 0.001mm
2. Sink: 160×160×130mm
3. Specimen specifications: cylinder φ50~60mm, height is about equal to diameter
The side length of the cube is 50~60mm, and the two end faces should be parallel and smooth
4. Dimensions: 500×500×150mm
5. Weight: 50Kg
According to the needs of different users, you can choose to configure the automatic test data collection system, which adopts digital analog sensing, and the computer software automatically collects test data, which saves manpower and manpower and increases the accuracy of test data. This automatic data acquisition system is mainly composed of multi-channel acquisition instrument, computer data acquisition software, displacement sensor, etc.
The main technical parameters of the system
(1) Displacement sensor range: 0-10mm; Accuracy 0.001mm 5pcs
(2) Multi-channel collector and computer data acquisition software functions
Real-time acquisition, monitoring, displacement and deformation, and curve graphics;
Multi-channel acquisition displacement can be realized;
The test data can be exported freely for data analysis;
The test time can be arbitrarily preset, and the test will be automatically stopped when the time comes;
The sampling time period can be set arbitrarily
Voltage: 220V; Frequency: 50Hz
