oil-less pump的意思|示意

This results in a much more benign forward start as less refrigerant is drawn into the compressor pump and the amount of oil pumped out of the compressor on start up is minimized.

这使得在更少制冷剂吸入到压缩机泵，并使启动时泵出压缩机的油量最小化时得到更良好的正向启动。

However, in research of water hydraulic axial piston pump, inertia items should play an important role because the viscosity of water is much less than that of oil.

然而，在水压轴向柱塞泵的研究中，由于水的粘度比油的粘度小得多，因此，惯性项就起着较大的作用。

Smaller does not mean less performance: the pump achieves the necessary oil volume and boosting outputs.

小并不意味着性能差，该泵将满足油量及输出量的要求。
