Other AbstractThe invention belongs to the field of ocean engineering, and particularly relates to a vacuumizing and bubble-discharging device of an underwater hydraulic compensation system. The device comprises a vacuum pump, a vacuum meter, a vacuum cup, an oil inlet ball valve and an oil draining ball valve. The vacuum cup communicates with the vacuum pump and the underwater hydraulic compensation system through pipelines correspondingly. The vacuum meter is arranged on the pipeline between the vacuum cup and the vacuum pump, an oil inlet connector is arranged on the pipeline between the vacuum cup and the underwater hydraulic compensation system, and the oil draining ball valve is connected to the bottom of the vacuum cup. Negative pressure in the vacuum cup is achieved through the vacuum pump, gas entering the vacuum cup is pumped away through the vacuum pump, and hydraulic oil entering the vacuum cup is drained through the oil draining ball valve. According to the vacuumizing and bubble-discharging device, small bubbles hidden in the compensation system and air dissolved in hydraulic oil can be separated out through the negative pressure achieved through the vacuum pump, and then pre-pressure of the compensation system is used for discharging bubbles on the surface of the hydraulic oil. The vacuumizing and bubble-discharging device effectively improves work efficiency of the compensation system and has the advantages of being high in exhaust efficiency, easy to operate and the like.
