The Development of Triaxial Seepage Equipment for Negative Pressure at Exit

Abstract:

Based on the existing triaxial seepage equipment, this paper choose the type of 2XZ-4 vacuum pump to provide negative pressure, type of CHF100A-1R5G-4 of Wei teng Ying transducer to control and make a constant negative pressure, and choose glass flowmeter to measure the flow of coal bed gas to explore the gas migration in coal reservoir during gas drainage. The triaxial seepage equipment after transformation can provide steady negative pressures on the range of-0.075MPa to-0.085MPa.The laboratory tests showed that the equipment can be used to conduct triaxial seepage experiments at different effective stress, different temperature and other conditions for negative pressure at exit.
