In order to retain the activity of microorganisms from abyssal sediment samples, this paper proposes the first device that can be used for the pressure-retaining transfer of seabed sediment samples. The device can transfer sediment from the sampler to the sample processing container and maintain the in-situ pressure of the sample, with the maximum pressure up to 100 MPa. The sample is stirred in the lower cavity of the transfer container and divided into the culture container by pressure difference control. In order to maintain the internal pressure of the device, a pressure stabilization system was designed, and a self-designed conical seal and right-angle combined seal were proposed. The high-pressure test is carried out through the experimental platform, the pressure is maintained for 1.5 h, and the pressure is actively reduced to verify the stability of the pressure stabilization system. The experimental results show that the pressure-retaining performance of the device can meet the transfer of 10,000 m of seabed sediment samples. [ABSTRACT FROM AUTHOR] |
