| Abstract: | The pressurization method of setting pressurization point between two-stage series circu- lating pumps is introduced.Combined with engineering example,for the heat-supply system in complicat- ed terrain,the operation results of the pressurization method by bypass pipe and the pressurization method of setting pressurization point between two-stage series circulating pumps are compared,and the latter has better result. |
