Manhole cover tester JJICL

resistanceperformancecompression

This instrument is mainly used to determine the ability of plastic manhole base to resist axial load. It is used to apply a specified load along the axial direction of the sample and continue for a specified time to observe the deformation, collapse, cracks or silver streaks of the sample, and measure the axial deformation of the sample before and after the inspection. Calculate the deformation rate. Standard GB/T 9647 GB/T 16826 Features 1. Large test space: The test space is large, and it can be suitable for large-scale test objects with a width of 2000mm, a length of 2000mm and a height of 3000mm. It is very suitable for the test of the test objects with large length and width. 2. Strong load capacity: The high-strength mechanical structure of four lead screws + four frame support columns adopts a precisely controlled hydraulic system to provide load power, and the maximum load can reach 600kN. 3. Excellent precision: The electronic balance weighing structure composed of multiple high-quality force sensors not only has high force measurement accuracy, but also has strong anti-bias load capacity. The industry-leading sampling technology, the effective resolution is as high as 1/500,000, and the effective data collection rate is as high as 50 times per second. 4. Diverse functions: It can realize various performance tests such as static load, compression, bending, ring stiffness, ring flexibility, flatness, shear, and creep; It can be set to constant force, constant displacement, constant deformation, constant stress rate, constant strain rate and other control methods to meet various test requirements.
