The oil cylinder will stop moving if the oil pressure is low .

如果油压低，油缸会停止移动。

Request stop climb at FL 220. 607. Our oil pressure reading is lower than normal.

请求在 FL 220 处停止爬升。607。的油压读数低于正常值。

They are high pressure fuel oil pipe breaking, crankcase explosion and loss of lube oil pressure.

是高压燃油管破裂、曲轴箱爆炸和失去润滑油压力。

For example, if we encounter low oil pressure, hydraulic fluid leak, we can follow QRH to deal with the problem.

例如，如果遇到油压低、液压油泄漏的情况，可以按照 QRH 来处理问题。

After he has started the engine, the pilot must check oil pressure and other indicators to be sure the engine is running properly at higher speeds.

动发动机后，飞行员必须检查机油压力和其他指示器，以确保发动机在较高转速下正常运行。

The cause may be hot bearing, seizure of pistons, scavenge fire and so on. Maybe the safety protection system functions due to low lube oil pressure and so on.

原因可能是轴承过热、活塞卡滞、扫气道火灾等。也可能由于润滑油压力过低等原因，导致安全保护系统动。

Even more importantly, relieving the  oil pressure from the rest of the pipe could allow gas bubbles to form inside the layers  of paper insulation, potentially damaging them and creating new places for faults to form.

更重要的是， 释放管道其余部分的油压可能会导致纸绝缘层内部形成气泡，可能会损坏并产生新的故障位置。
