Description

滑板弧面转子泵
技术领域
本发明涉及一种滑板弧面转子泵，尤其涉及一种利用滑板隔离吸、排液区的流体输送泵，属于流体输送设备技术领域，特别适用于高粘度、甚至有吸附性流体的输送。
背景技术
叶片泵是一种应用广泛的流体输送机械，它主要包括泵体、泵盖、转子、叶片、配流盘、泵轴等。工作时，利用离心力使叶片沿转子槽向外与泵体内表面内表面保持接触，从而形成一个密封的容腔，随着转子的旋转，容腔容积跟着变化，从而连续不断地吸入和排出流体。
单作用叶片泵转子旋转一周，容腔内的体积循环变化一次，由于泵体只有一个进口和一个出口，转子径向受力不平衡，径向力大，影响轴承及密封材料的使用寿命。双作用叶片泵转子旋转一周，容腔内的体积循环变化两次，由于泵体有两个进口和两个出口，转子径向受力平衡。但叶片泵叶片数量较多，且当相邻两叶片同时位于吸排口之间时，会形成封油区因而可能出现困油现象。
发明内容
为了改善单作用叶片泵中转子径向力不平衡，和叶片泵叶片数量多及可能引发困油现象的状况，本发明采用的技术方案是：一种滑板弧面转子泵，主要包括泵体、弧面转子、滑板、滑板槽、圆柱滚子、弹簧、转子轴等。弧面转子的形状类似于倒圆角后的凹弧边正四边形，其中四段小圆弧位于凹弧边正四边形的四个角上。泵体上两条滑板槽分别偏置于弧面转子中心的两侧，滑板安装于滑板槽内，在弹簧力作用下，滑板底部的滚子始终与弧面转子的表面保持接触。在远离吸、排液口的位置，大圆弧、小圆弧，和泵体内壁形成封闭的、且容积不变的容腔，该容腔将流体无压缩地从吸液口输送到排液口，并继而被滑板、圆柱滚子分隔为吸液腔和排液腔。工作时，弧面转子由转子轴驱动，在泵体的横截面内，两个排液区的逐渐面积变小，两吸液区的面积逐渐增大，因而使排液腔容积变小，挤出流体；吸液腔容积也变大，吸进流体。
上述方案中，所述弧面转子的截面由八段圆弧组成，四段相同的小圆弧和四段相同的大圆弧间隔相切联接而成。
上述方案中，所述两滑槽的彼此平行，并相对于弧面转子呈中心对称。
上述方案中，所述滑板槽相对于弧面转子的回转中心存在一定的偏心距。
上述方案中，所述的滑板的横截面为矩形，并在底部装有一个圆柱滚子，滚子的长度、滑板的宽度、弦线转子的厚度均相同。
本发明的有益效果是：两滑板对转子的作用力方向相反，可相互抵消；两吸液口和排液口相对于转子中心呈中心对称布置，转子所受径向力平衡，所以与单作用叶片泵相比，改善了转子轴的受力状况，可延长轴承和密封材料的使用寿命；转子容腔离开吸、排液口后，容积不再变化，所以可避免困油现象；因本发明滑板弧面转子泵只需两个滑板，且滑板槽开在固定的泵体上，滑板是在固定的泵体中移动，所以相比现有叶片泵(叶片多，且叶片是在转子中移动)结构简单；滑板与滑板槽之间的摩擦与磨损不会影响到泵的周向密封，所以相对于当前的叶片泵，实现周向密封的难度较小；当所输送介质粘度较大时，滑板槽对滑板、滑板对弦线转子还有刮下表面附着的物的功能。本发明滑板弧面转子泵，尤其适用于高粘度、甚至有吸附性流体的输送。

具体实施方式
参照附图1，一种滑板弧面转子泵，包括沿轴向开有两个滑板槽的泵体5，弧面转子8，轴10，键6，滑板2，圆柱滚子9。工作时，弧面转子8在键6的带动下，随轴10一起转动，弧面转子8与泵体5之间形成四个容腔7，当容腔7转到与滑板2相遇时，容腔就被滑板2分隔为排液腔(与排液口1相连通)和吸液腔(与吸液口4相连通)。如图3所示，随着弧面转子的转动，两排液腔容积越来越小，致使流体从由两个排液口1被挤出，同时两吸液腔容积越来越大，致使流体从由两个吸液口4排出被吸入。
如图2所示，滑板2底部装有圆柱滚子9，它使本来滑板2与弧面转子8之间的滑动摩擦变为圆柱滚子9与弧面转子8之间的滚动摩擦，大大减小摩擦和磨损。滑板在顶部弹簧压力的作用下，通过底部的滚子9与弧面转子8始终保持接触，同时弧面转子8通过滚子9推动滑板2在槽内移动。
如图1所示，左上角和右下角两个滑板2弧面对转子8的作用力大小相等、方向相反，可相互抵消；左上角和右下角两个吸液口4和排液口1相对于转子中心分别呈中心对称布置，使得转子所受径向力平衡，这改善了转子轴10的受力状况，并可延长其上轴承和密封材料的使用寿命；转子容腔7离开滑板2之后，容积不再变化，所以可避免困油现象。
