为了克服混合轴承中孔板式节流器和毛细管式节流器的空间限制，提出了一种非典型的长孔板式节流器并建立了其实验模型。通过对孔板式节流器和毛细管节流器的结构和流量分析，提出了一种用孔板代替整个轴承的长孔板式节流器和可行的实验建模方法。对长径比4～10、压差1.5～5.5MPa下的水膜节流器进行了流量测试，建立了长孔板节流器的实验模型。结果表明，非典型结构的限制器需要通过实验来建模。非典型节流器的流动规律与典型孔板式节流器相似，节流模型接近湍流模型。
To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of orifice plate instead of the whole bearing. The flow rate of water film restrictors are tested under the aspect ratio of 4-10 and the pressure difference of 1.5-5.5MPa and the experimental model of long orifice-type restrictor is established. The result shows that the restrictor of atypical structures needs to be modeled by experiment. The flow discipline of atypical restrictor is approximate to typical orifice-type restrictor and the throttling model is a nearly turbulent model.
