Description

平动转子泵及发动机 技术领域
本发明涉及容积泵及发动机，尤其是真空泵，压缩泵，空压机，输送泵，燃气轮机、内燃机、透平机、计量泵等领域，具有压缩比高、余隙容积小、结构简单、容易加工、振动小噪音低、稳定可靠等特点。
背景技术
容积泵主要利用腔体容积的变化来吸入和挤出流体，同时完成能量转换过程，比如液体透平或气体透平装置将流体的动能及势能转换成机械能。现有的滑阀泵体积大振动大多用于低转速工况、滚动活塞式压缩机密封困难、稳定性差、余隙容积较大，多用于小功率工况，且需要止回阀工作，曲柄连杆式活塞发动机体积大、侧压力大、稳定性差。
发明内容
本发明主要解决的技术问题是在降低现有容积泵制造难度，提高工作稳定性及使用寿命的前提下还能减小机械装置体积，适用于高转速工况工作，在获得极小的余隙容积的基础上实现高性能密封，流体入口和流体出口可不需要止回阀工作，减小机械装置的振动及噪音。当本发明的平动转子泵及发动机具有多级递增或递减的工作容积结构时，设置前级的流体出口和次级流体入口连通可作为多级压缩机或多级膨胀做功机，作为往复式发动机使用时可消除活塞侧向压力，可较大范围调整缸径行程比同时提高发动机传动效率及热效率。
为实现上述目的，本发明提供以下的技术方案：
一种平动转子泵及发动机，包括偏心轴，转子和缸体，所述的偏心轴的偏心轴第一轴可转动的设置在缸体上，所述的偏心轴的偏心轴第二轴可转动的设置在转子上，在转子和缸体上分别设置有转子滑槽和缸体滑槽，滑块同时在缸体滑槽和转子滑槽内滑动，所述的转子的外壁面设置有一个与转子滑槽平行的平面或所述的缸体的内壁面设置有一个与缸体滑槽垂直的平面，且滑块与转子的外壁面平面或缸体的内壁面平面形成接合密封将位于滑块两侧的转子和缸体之间的空间隔开，同时与转子的外壁面和缸体的内壁面形成接合密封的区域使处于转子和缸体之间的 内部空间分割成2个独立的空间，所述的2个独立的空间容积随转子转动发生周期性变化。
作为对本发明的改进，在所述的缸体的内壁面或转子的外壁面上圆周分布设置有一个或多个弹性密封件，当缸体的内壁面或转子的外壁面接近或靠近且位于该弹性密封件时，该弹性密封件两侧的流体被隔开。
一种活塞平动转子泵及发动机，包括偏心轴，转子和缸体，所述的偏心轴第一轴可转动的设置在缸体上，所述的偏心轴第二轴可转动的设置在转子上，在转子和缸体上分别设置有转子滑槽和缸体滑槽，滑块同时在缸体滑槽和转子滑槽内滑动，在转子滑槽上设置有气缸，在对应气缸的滑块上设置有活塞，活塞在气缸内滑动。
作为对本发明的改进，在所述的缸体和转子圆周分布设置有多个转子滑槽及多个缸体滑槽，以及对应设置有多个滑块，每个滑块在对应的转子滑槽及缸体滑槽内滑动，在多个转子滑槽上设置有多个气缸，滑块上设置有多个活塞在对应的气缸内滑动。
作为对本发明的改进，在偏心轴上设置有流体入口和流体出口，在转子的气缸上设置有流体通道，当流体入口或流体出口旋转至所述的气缸的流体通道所在位置时，所述的流体入口或流体出口与该气缸直接贯通使该气缸处于进气或排期状态。
作为对本发明的改进，当平动转子泵及发动机具有多级递增或递减的工作容积结构时，设置前级的流体出口和下一级流体入口连通可作为多级压缩机或多级膨胀做功机。
采用以上技术方案的有益效果是：通过在缸体和转子上设置偏心轴及缸体滑槽和转子滑槽，滑块同时在缸体滑槽及转子滑槽内滑动使转子构成平动公转运动。在缸体或转子上设置与滑块作用的隔离密封构为平面结构，使滑块实现高效可靠的平面对平面的密封形式且滑块与对应的密封平面之间保持恒定的小间隙距离(或者采用恒定弹性补偿密封)从而达到良好的密封效果，当本发明装置作为发动机(柱塞泵)使用时在转子上设置有气缸，由于活塞在气缸内工作时其作用力合力过偏心轴第二轴的轴心线，所以消除了活塞的偏转/扭转作用力，使活塞处于无侧压 力作态，同时流体直接对偏心轴作用减少传动损失，当在缸体和转子圆周分布设置有多个转子滑槽及缸体滑槽，以及对应设置有多个滑块，在多个转子滑槽或缸体滑槽上对应设置有多个气缸，在对应的滑块上设置有多个活塞在对应的气缸内滑动时，设置有与气缸容积变化对应的偏心轴第二轴上的流体入口和流体出口时，可无需阀门作为柱塞泵、压缩机、透平机、燃气轮机等应用。
