GY-LHGR pouring type mixture penetration tester Introduction: Applicable standard: JTG/T 3364-02-2019 Appendix J "Penetration Test for Cast Asphalt Mixtures" JTG E20 has added a new standard "T 0776 Penetration Test for Cast Asphalt Mixtures. The floor standing structure is supported by four universal wheels and mainly consists of a frame, a 3-station loading and testing device, a constant temperature water tank, a gas supply part, a touch screen, control software, etc. characteristic: 1. This instrument is controlled by a 7-inch color touch screen PLC, with stable and reliable operation, simple interface operation, and flexible parameter modification. 2. The touch screen interface information can display and view real-time load time and displacement relationship curves and values. 3. Equipped with internal LED lighting below the crossbeam for easy and clear observation of the testing process below. 4. Equipped with three specimen testing devices, it can simultaneously test the penetration of three specimens, greatly reducing the testing time. 5. The penetration rod adopts a split design, with a counterweight filling area inside to ensure that the weight of the penetration rod is constantly pressed by a cylinder instead of a weight. The cylinder loading pressure is controlled by an electromagnetic valve through an air compressor, and the pressure transmitter collects real-time loading pressure data to ensure constant loading pressure, eliminating the need for workers to frequently move weights, reducing safety hazards, and achieving instrument automation and lightweight. 6. Real time collection of penetration rod displacement data through high-precision displacement sensors can achieve measurement accuracy, avoid errors in manual readings and calculations, and make the tested penetration values more accurate. 7. Separate the pre compression data and penetration data for recording and processing, making the data judgment clearer and more understandable. 8. Lower front storage cabinet, convenient for storing trial molds and testing equipment. 9. Semi closed water bath, equipped with magnetic pump to ensure uniform temperature and maintain the sample 10. Historical experimental data can be viewed with a micro printer, allowing for one click printing of experimental data or exporting and printing from a USB drive. Technical parameters: 1. Workstation: 3 or 5 2. Penetration rod diameter: 25.2mm 3. Penetrating rod weight: 24.5N 4. Total weight of load (weight+penetration rod): 515+9.8N 5. Temperature control accuracy: ± 0.2 ℃ 6. Displacement measurement range: 0-20mm 7. Displacement accuracy: ± 0.01mm 8. Internal dimensions of the trial mold: 70.7 (cube) ± 0.5mm 9. Pre pressing time: 10 minutes 10. Test time: 60 minutes
