Abstract
A sediment pressure-holding transfer device developed based on abyssal sediment fidelity sampler is disclosed, which uses a vacuum pump to discharge a gas in the device, uses a high-pressure pump as a power source to perform a pressurization process, uses gravity of a sample to perform a first transfer, and uses a high-pressure impurity pump and a safety valve to perform a second transfer of a sample mixture, in its structure, a high-pressure-resistant and corrosion-resistant material is used as a main material of the device, the device mainly comprises a mechanical system and a hydraulic system, the mechanical system is used as a main frame of the device and is a basis for ensuring operation of the device; the hydraulic system is used as a core of the device and is a key to ensure success of sediment transfer.
