oil-film whirl

基本解釋

The result shows that oil-film whirl of sliding bearing with the turbine generator is easily influenced by the boundary conditions.
針對(duì)某船用汽輪發(fā)電機(jī)組出現(xiàn)的振動(dòng)異常情況，通過(guò)機(jī)組振動(dòng)測(cè)試分析，確定機(jī)組振動(dòng)異常由軸承油膜渦動(dòng)引起。
The results show that the change of oil-film whirl angle makes the characteristics of journal bearing change greatly, and the more the whirl radius is, the more the influence is.
結(jié)果表明，油膜渦動(dòng)角度的變化對(duì)三油楔固定瓦滑動(dòng)軸承的靜、動(dòng)特性和穩(wěn)定性將産生很大的影響，且這種影響隨油膜渦動(dòng)半逕增大而增大。

It is concluded that the causes of sudden vibration are oil film whirl and thermal unbalance of generator rotor resulting from interturn short-circuit and hindered winding expansion etc.
認(rèn)爲(wèi)突發(fā)性振動(dòng)原因是運(yùn)行中轉(zhuǎn)子的油膜渦動(dòng)和匝間短路、線(xiàn)圈膨脹受阻等引起的熱不平衡。
