Overview
XH-DH100 rock point load tester is a Portable test instrument of Tiandi Spark brand, using liquid crystal display, force value accuracy of 0.01kN, using fast charging battery, Continuous Operating Time more than 400 hours, suitable for rock point load test, can measure any state sample, Measurement range 0mm-90mm.
Features
1. Adopt horizontal structure, convenient afterburner and good Stability
2. The reaction frame adopts a cylindrical structure, which is good for neutrality, not eccentric, and has a strong and compact structure
3. The jack is installed on the cylinder shell body, which is processed with high-quality high-strength materials, beautiful appearance, light weight and easy to carry
4. The loading cone is made of cemented carbide material, with high strength and durability
5. Using Strain Sensor and LCD instrument to form an independent electronic force measurement system with high resolution, High Test accuracy and convenient reading
6. Powered by rechargeable lithium batteries, convenient for field use
Principle
Rock point load tester applies point load to rock samples by loading cones, uses strain-type Sensor measurement of load force value, liquid crystal display instrument displays and memorizes peak value in real time, calculates rock uniaxial compressire strength according to point load strength index, and determines rock anisotropy and other parameters.
Applications
Field tests of geological, mining, hydropower, railway, transportation and other construction projects
Standards
International Society of Rock Mechanics Committee on Test Methods Standard
Steps
1. Prepare rock samples, which can be core samples or irregular samples
2. Place the specimen between the loading points and adjust the spacing
3. Start the instrument and apply the load through the jack
4. Observe the LCD display reading and record the peak force value
5. Calculate point load strength index and related parameters based on test data
Notice
• Ensure that the minimum length of the sample in the loading direction is not less than 40mm
• The maximum width of the sample does not exceed 90mm
• Operating temperature range -20 ° C to 45 ° C
• Charge regularly to ensure battery life
• Avoid overload use, the maximum output is 100KN
• Keep the loading cone clean to avoid damaging the carbide surface
