Pneumatic high pressureConsolidation instrument (3200Kpa)

The pneumatic fully automatic consolidation instrument integrates mechanical, electronic technology, sensor automatic detection technology, and computer technology, automatically completes loading and unloading and data acquisition functions, and can replace traditional lever type consolidation instruments. The instrument has a compact structure, small size, light weight, and is easy to carry and use.

YUC. YJZG16-1Wtypewireless transmissionpneumatictallThe compression consolidation instrument, based on the principle of pure air pressure, utilizes the theory of suspended loading of rolling diaphragms in a specific cylinder. The axial consolidation pressure is applied to the soil sample in the consolidation container by the sensing piston through a linear bearing and a guide sheath. The resulting deformation of the soil sample can be obtained through data acquisition and processing, and a series of compressibility indicators such as compression coefficient can be obtainedav 、 compression modulusEs 、 Volume compression coefficientmV and so on. The practical surface pressure consolidation instrument has the characteristics of light weight, small volume, accurate output, stable performance, and easy operation, which can reduce the labor intensity of testing personnel. Therefore, it is an ideal modern intelligent testing instrument.

2.1 Air pressure controller

Using imported proportional valves to control air pressure, the controller does not consume additional air source during stable operation of air pressure control, and the working time of the same air source can be greatly extended. All containers can be pressurized simultaneously without the need for grouping, ensuring a monotonic increase in pressure and avoiding the drawbacks of loading in the order of grouping. This ensures precise synchronization of loading times for all containers. The range of air source pressure of the air compressor can be controlled, and the touch screen displays the air source pressure and current consolidation pressure data. It can receive software commands from the upper computer to automatically apply consolidation pressure step by step, and also supports manual operation. The entire test operation is convenient, simple, and fast.
