冶金厂矿废水泵联运增效改造

Renovation of Wastewater Pump in Metal Plants and Mines

冶金厂矿输送废水的离心水泵常会在低效区工作。选择一台合适的小离心泵与主泵联运,使主泵工况点移到高效区,增效明显。介绍废水泵联运增效原理方法和实例。

The centrifugal pumps for transporting waste water in metal plants and mines often work at a low efficiency. However if they are cooperated with some small auxillary pumps, the operating point will be risen and the efficiency of the main centrifugal pumps will be increased dramatically. The paper introduces the principles and illustrations of the cooperated main pumps and auxillaries.
