Working principle of high speed pipeline pump

High speed pipeline pump

High speed pipeline pump is a new type of chemical process pump. It can replace reciprocating pump and multi-stage centrifugal pump. The utility model belongs to a special centrifugal pump, which is widely used in oil refining and chemical equipment. 

High speed pipeline pump in the structure compared with ordinary centrifugal pump, more than the speed of the box, and the lubrication method for forced lubrication. Compared with the multistage centrifugal pump with the speed increasing box and the forced lubrication, the utility model has the advantages of compact structure and simple lubrication system. 
Similar to the ordinary centrifugal pump, high-speed pipeline pump to take a substantial increase in the speed of the way to improve the pump head, the pump speed of 10000r/min or more, some imported pump speed exceeds 30000r/min. 
High speed pipeline pump also exists hump curve and cavitation. Due to the high speed, high speed pipeline pump replacement prone to cavitation, so the operating range is smaller than the ordinary centrifugal pump. The single-stage impeller and high speed structure are adopted to replace the multi-stage pump, which reduces the volume loss and the mechanical loss of the impeller.
