Electric Percussion Testing Machine For Coarse Soil

Product introduction

DDJ30-6 coarse-grained soil electric compacted instrument conforms to the national standard of the People's Republic of China "Soil Test Regulations" GB/T 50123-2019, the Ministry of Electric Power of the People's Republic of China "Coarse-grained Soil Test Regulations for Hydropower projects" DL/T5356-2006. This instrument is suitable for compaction test of coarse soil samples containing clay soil with a maximum particle size of 60mm and which cannot be drained freely.

DDJ electric compactor is a new product upgraded on the basis of DDJ30-5B. The original hollow hydraulic cylinder is improved to be driven by variable frequency motor gear, and the hollow core rack and ratchet grab hammer head. Speed up the return speed and no leakage, simplify the mechanism, improve the compaction efficiency. The programmable controller is used to control the work of the system, and the touch screen controls the operation display and records the total number of hits. Photoelectric control to adjust hammer drop height, automatic control punching times, each round of punching automatic tracking control hammer drop height. The instrument has the advantages of uniform hammering and convenient operation. It is an ideal test instrument for the compaction test of coarse soil in survey and design, scientific research units and colleges and universities.
