Abstract
An active pressure compensator for deep-sea sampling includes a spring chamber, a cam piston pump, and a circuit chamber; the spring chamber is configured to provide compensation liquid for the cam piston pump; the cam piston pump is configured to be able to draw liquid from the spring chamber and pump liquid to the circuit chamber; the circuit chamber is configured to be connected to a mechanism to be pressurized, and is provided therein with a pressure sensor and a control circuit board, the pressure sensor is configured to detect pressures of the compensation liquid from cam piston pump and the mechanism to be pressurized, the control circuit board is configured to control working of the cam piston pump based on pressure data feedback from the pressure sensor and thereby realize active pressure compensation for the mechanism to be pressurized. A pressure compensation method using the compensator is further provided.
