Overview
The XH-DH50 rock point load tester is a Portable test instrument of Tiandi Spark brand. It adopts liquid crystal display, force value accuracy of 0.01kN, fast charging battery, long standby, Continuous Operating Time of more than 400 hours. The instrument is suitable for rock point load test, which can measure the rock point load strength index, and then calculate uniaxial compressire strength, determine rock anisotropy, determine efflorescence zone, estimate rock drilling speed and rock classification.
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, meeting the testing requirements of high-strength and large-core samples.
3. The jack is installed on the cylinder shell body, and is processed with high-quality and high-strength materials. The structure is compact and reasonable, the appearance is beautiful, the weight is light, and it is 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 outdoor use.
Principle
Rock point load tester applies point load to rock samples by loading cones, uses strain Sensor measurement of force value, and displays and remembers peak value in real time through liquid crystal display instrument. According to the measured point load strength index, parameters such as uniaxial compressire strength of rock can be calculated, which is suitable for on-site rapid testing.
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, whether core or irregular, without the need for specialized machining.
2. Place the specimen between the loading points to ensure alignment.
3. Start the instrument and apply the load through the jack.
4. Observe the liquid crystal display meter and record the peak force value.
5. Calculate the point load strength index and related parameters according to the test data.
Notice
• Ensure that the minimum length of the specimen in the loading direction is not less than 40mm.
• The maximum width of the sample does not exceed 90mm.
• Operating temperature range is -20 ° C to 45 ° C.
• Regularly check the battery level to ensure battery life in the wild.
• To avoid overloading, the maximum output of the jack is 50kN.
