离心式增压压缩机需采用止推轴承,才能保证在止推轴颈线速度达120米/秒,单位负载达100公斤力/厘米2时,运转可靠,工作经济。离心式压缩机用的高速止推轴承的设计方法到现在也没有变。在这种场合上,采用已知的计算方法是困难的,因为许多参数,例如与转子自由部分同润滑液摩擦（圆盘损失）有关的功率损失,是根据半经验关系曲线〔1〕考虑的,而这些关系曲线的应用范围有局限性。
Centrifugal booster compressors need to use thrust bearings, in order to ensure that the thrust neckline speed of 120 m / s, the unit load up to 100 kg / cm 2, reliable operation, economic work. The design of high-speed thrust bearings for centrifugal compressors has not changed so far. In this case, the known calculation method is difficult because many parameters, for example the power loss associated with the free friction of the rotor with lubricating fluid friction (disc loss), are considered on the basis of the semi-empirical relation curve [1] , And the scope of application of these relationship curves has limitations.
