摘要： A pneumatic liquid on-line automatic balancer of a rotor is disclosed in the invention, including a sealed balancing disk rotating with a balanced rotor about a central axis and a pressure transfer device mated with the sealed balancing disk. At least two pairs of centrosymmetric chamber filled with appropriate balancing liquid are evenly distributed in the sealed balancing disk. The pressure transfer device controls compressed gas in and out of the chamber and makes the balancing liquid controllably flow in each pair of chambers to achieve the dynamic balance of the rotor. A communicating channel of the balancing liquid is provided between the outer edges of each pair of the chambers. The communicating channel of the balancing liquid is one and the center of the communicating channel of the balancing liquid is communicated with the balancing channel pointed to the center of rotation. The other end of the balancing channel is communicated with an empty channel axially located near the center of rotation. The other end of the empty channel is opened to atmosphere. The invention is of permanence balance ability and is suitable for a high-speed rotating device.

摘要翻译： 在本发明中公开了一种转子的气动液体在线自动平衡器，包括一个围绕中心轴线的平衡转子旋转的密封平衡盘和与密封平衡盘配合的压力传递装置。 填充有适当平衡液体的至少两对中心对称室均匀分布在密封平衡盘中。 压力传递装置控制压缩气体进出室，并使平衡液体可控制地流入每对腔室，以实现转子的动平衡。 平衡液体的连通通道设置在每对室的外边缘之间。 平衡液体的连通通道是一个，平衡液体的连通通道的中心与指向旋转中心的平衡通道连通。 平衡通道的另一端与轴向位于旋转中心附近的空通道连通。 空通道的另一端向大气开放。 本发明具有永久性的平衡能力，适用于高速旋转装置。
