| Abstract: | Discusses the handling measures for the pressure pump failure occurred in a user branch and the adjustments of the pump or valve in heat source and other user branches needed to keep the constant flow in those branches,and the practicability of limited heating when the heat source circulating pump failed and the influence of performance curves of user pressure pump and zero pressure difference point on the heating capacity in the limited heating operation.Provides the selection principle of user pressure pump and the basis for the standby pumps. |

| Keywords: | heating system with distributed pumps failure condition limited heating zero pressure difference point |
