Abstract
The present application disclose a device for preparing rock samples with different moisture contents, which comprises a sample container, wherein two ends of the rock sample are respectively connected with a first steam inlet and a first steam outlet of the sample container; the first steam outlet, a pump and a gas-liquid separator are connected in sequence, a gas outlet end of the gas-liquid separator, a steam compressor and the first steam inlet are connected in sequence, and a liquid outlet end of the gas-liquid separator, a steam generator and the steam compressor are connected in sequence. The water vapor in the sample container is pumped into the gas-liquid separator by the pump to separate low-temperature water vapor and condensate, and the low-temperature water vapor and condensate form high-temperature and high-pressure steam again and return to the inside of the sample container. The water in the steam generator always circulates inside the preparation device. The measuring instrument measures the reduction of the water in the steam generator, and subtracts the pre-recorded reduction of the water in the steam generator when the preparation device is idling, so as to obta…
