I. Overview

YUC.YJZQZ16-1 intelligent pneumatic medium-pressure consolidation instrument based on the principle of pure pressure, using the rolling diaphragm in a specific cylinder suspension loading theory, by the sensing piston through the linear bearing and the guide sheath to apply axial consolidation pressure to the soil samples in the consolidation vessel, resulting in soil deformation, through data acquisition and processing can obtain a series of compressibility indicators, such as compression coefficient av, consolidation coefficient Cv, compression modulus Es, volume compression coefficient Mv. The practice shows that the pneumatic cementing instrument has the characteristics of light weight, small size, accurate output, stable performance and simple operation, and can reduce the labor intensity of the test personnel. is an ideal modern intelligent test instrument.

II. Performance characteristics:

• Wireless transmission (optional), data visualization
• Automatic computer control acquisition and processing, automatic completion of loading and unloading and data acquisition function
• The inlet proportional valve is used to control the air pressure. When the air pressure control is stable, the controller does not consume extra gas source, and the working time under the same gas source can be extended continuously
• Fast connection of line and pipeline, easy maintenance and easy field use
• Automatic zeroing to balance the weight of containers and soil samples
• Electrical pressure stabilizer valve from loading to stabilization <2 seconds, all containers can be pressurized at the same time, one step in place without grouping
• Medium pressure container and main engine: Double connection structure, stainless steel material, frame structure, small size and light weight, convenient for packing samples, convenient for field use
• Simultaneous control of 2-64 containers
