困油 meaning in Chinese
packeted oil
pocketed oil
Examples
- If the coefficient of engagement overlap decreases , the flow aggrandize , trapping volume and the flow pulsating ratio decreases
随着齿轮啮合重合系数的减小，齿轮泵的流量增大，困油容积和流量脉动率减小。 - Then a formula about flow of the gear pump and the coefficient of engagement overlap to find is obtained by area method . through analysis contact ratio and overlap ratio has the effect on the volume oil and the flow pulsating ratio
然后采用面积法求得齿轮泵流量与齿轮啮合重合系数的关系式，研究了齿轮啮合重合系数对齿轮泵困油和流量脉动率的影响。 - On the condition the trapping characteristics of whole profile meshing helical pump are lucubrated by theory for the first time , and the select range of the helical angle that can eliminate completely the trapping of whole profile meshing helical gear pump is also obtained

首次对普通斜齿齿轮泵的困油特性进行深入的理论研究，分别讨论了有侧隙和无侧隙时普通斜齿齿轮泵转子的端面重合度与困油现象之间的理论关系，以及困油容积随转角的变化关系，得到了完全消除斜齿齿轮泵困油冲击的螺旋角机械科学研究院博士学位论文的选择范围。 - These characteristics and phenomenons have effect on the quality of gear pump , and it is difficult relatively to research them by theory . at present the research is limited to the phase of examination testing . theoretic research of the characteristics and the phenomenons of polymer gear pump are blank in china when the gear pump feeds the viscous polymer liquid of chemical flow with high temperature and high pressure
齿轮泵除具有流量和容积效率、扭矩和机械效率、功率和总效率等基本特性外，还存在着困油、噪声和气穴等现象，这些特性和现象直接影响齿轮泵的质量，对斜齿齿轮泵的这些特性和现象的理论研究难度较大，目前大多仍局限于实验测试研究阶段，而聚合物齿轮泵在输送化工流程中的高温、高压的粘流态聚合物时特性的理论研究在国内基本还处于空白。
