Double axis bearing rotor pump blade, comprising a rotor shaft (1), (2), (3), disc shaft end cover (4) and shaft seat (5); a rotor (1) respectively with its axis through the coupling shaft (2) is engaged with a row is arranged in the pump body. (2) in the end of antithetical couplet shaft through the shaft disc (3) installed at the same time, the antithetical couplet axis (2) respectively through the outer end of the shaft seat (5) is installed in the end cap (4). The connecting shaft and extend through the end cap is fixed to the outer end of the rotor blade by mounting improved double bearing installation, greatly reducing the risk of deformation of the shaft, but also reduces the risk of rotor wear and mechanical seal leakage, prolongs the service life of the pump, reduce the operation cost. Between the rotor and the inner wall of the valve shell, the utility model can eliminate the influence of the foreign body clamping into the normal work of the pump body, and the utility model has the advantages of low cost, good quality and performance improvement, and stable operation of the rotor pump.

技术介绍
转子泵又称胶体泵、凸轮泵、三叶泵、万用输送泵等,转子泵属于容积泵。它是借助于工作腔里的多个固定容积输送单位的周期性转化来达到输送流体的目的的。电动机的机械能通过泵直接转化为输送流体的压力能,泵的流量只取决于工作腔容积变化值以及其在单位时间内的变化频率,而与排出压力无关;转子泵在工作过程中实际上是通过一对同步旋转的转子。转子由箱体内的一对同步齿轮进行传动,转子在主副轴的带动下,进行同步反方向旋转。使泵的容积发生变化,从而构成较高的真空度和排放压力。特别适合卫生级介质和腐蚀性、高粘度介质的输送。转子泵外壳内部的一对转子采用联轴整体组装,两转子将转子室分隔成几个小空间,并按a→b→c→d的次序运转。运转至位置a时,只有I室中充满介质;到位置b时,B室中封闭了部分介质;到位置C时,A室中也封闭了介质;到位置d时,A室B室与Ⅱ室相通,介质即被输送至出料口。现有技术中,通常应用的Q型泵的转子叶片采用悬挂式安装,转子运行过程中,由于受到外力,如大的重物卡在叶片与外 ...
