Mid-open pump is also called mid-open double suction pump. There is a gap at the edge of the inlet and the inner wall of the pump. The gap is high and low pressure area on both sides. The gap is relatively large. High-pressure water will leak into the low pressure area through this gap, which means the inlet position, so as to reduce the efficiency of mid-open pump.


In fact, from the point of view of reducing backflow and improving impeller condition, the smaller the leakage gap is, the better, but we need to pay attention to the gap is not too small, otherwise it will produce a lot of mechanical wear.


But if the gap between the middle and open pumps is relatively small, the impeller will friction with the pump when it rotates, causing a certain degree of wear and tear. Usually, leak detection is used, which requires professional inspection.


If the gap is large, the slight wear and tear will occur. Impeller faults may occur in the heavy pump, which will affect the efficiency of the pump. It is suggested that the gap should be within 5 mm.


      中开泵又叫做中开双吸泵在入口的边缘还有水泵的内壁连接处有一个缝隙,缝隙两侧是高低压区域,缝隙比较大,高压水就会通过这个缝隙漏到低压区,也就进口位置,从而达到降低中开泵的效率。

其实单单从中开泵缝隙来看,减少回流以及改善叶轮状态来看,中开泵的减少回流以及改善叶轮的状态来看,减漏缝隙越小越好,但是需要注意缝隙也不要太小,否则将会产生很大的机械磨损。

但是如果中开泵交接缝隙比较小的时候,叶轮转动时候会跟水泵内部发生摩擦,造成一定程度的磨损。通常情况下,会采用检漏,这就需要专业人士来检查。

中开泵如果要是缝隙较大的话,轻则磨损,重者可能会发生叶轮故障,影响水泵效率,建议缝隙在五毫米之内比较合适。
