潜水员必须吸入压缩空气才不致受到周围海水压力的伤害。
Divers must breathe compressed air to keep from being crushed by the weight, or pressure, of the surrounding water.
高压泵自动欠压保护，当供水泵的海水压力低于0.05Mpa 时，设备自动停机并报警。
High pressure pump equipped with low-pressure protection device, when pre-treated sea water pressure is less than 0.05Mpa, the system will shut down automatically give alarm fattention.
在封井过程中，他们必须把用于在钻探过程里，保持钻井与海水压力相当的高密钻井泥更换掉：因为上方的海水的压力低于底下油气的压力。
As part of that process they had to replace the dense drilling mud, which was used to keep the well under pressure while it was drilled, with sea-water.
为了使水下液压系统适应不同深度下的作业要求，在系统中设置压力补偿器，使系统的回油压力与海水压力相等，并随海水深度变化自动调节，从根本上避免了海水压力的影响。
To make it adapt to full ocean depth, a pressure compensator is adopted to balance the pressure inside and outside of the tank, which makes system pressure be established on seawater pressure.
