求翻译：叶片密封为多层V型密封，保证叶片不漏油。轮毂高位油箱使转轮内保持稳定压力，且油压高于外部流道水压，从而使外部水不能内渗。是什么意思？

Blade seal for multi-layer v type seal to ensure that the blade is not leaking. Wheel high tank so that the runner to maintain steady pressure, and oil pressure is higher than the external flow water pressure, so that the external water seepage can not be within.

Multi-level Leaf seal V seal to ensure that leaf does not leak. Hub high fuel tank to maintain a constant pressure within the wheel, and oil pressure above the external pressure, flow, so that should not be placed in an external water seepage.

Leaf blade seal for multi-layered V seal, guarantee leaf blade not oil leak.The wheel hub top digit fuel tank makes in the runner to maintain the uniform pressure, also the flowing tubing head pressure is higher than exterior flow channel hydraulic pressure, thus enables exterior water in to infiltr

Blade sealing for multi-layer v-seal, ensure the blade does not leak oil. Wheel high runner remains stable pressure inside of the fuel tank, and oil pressure higher than the external pressure of the flow channel, so that external water seepage.
