三、单级泵输送系列高温冷凝水回收装置1．问题的提出在蒸气凝结水回收工作中，经常遇到须要将高温水输送或提升一段距离而不一定送进锅炉的情况。这时，如采用多级泵系列的回收装置，在运行上是很不经济的。为此，有必要研制一个扬程相对低的输送系列产品。与多级泵系列产品比
Third, single-stage pump series of high temperature condensate recovery device 1. PROBLEM PROBLEMS In the case of steam condensate recovery, it is often the case that the hot water needs to be transported or lifted a distance without necessarily being sent to the boiler. At this time, such as the use of multi-stage pump recovery device, in operation is very uneconomical. To this end, it is necessary to develop a relatively low lift delivery products. Compared with the multi-stage pump series
