Water injector characteristic curves and their application to heating engineering

Obtains the water injector characteristic equation based on liquid-to-liquid ejector design method proposed by Sokolov. Develops four characteristic curves of water injector which apply to both the engineering design and the operational conditions, when five factors of the water injector characteristics are considered and the water injector efficiency equation is considered. Through the water injector characteristic curves, analyses the running status of the water injector. When the outside heating network is centrally regulated, the water injector can run normally with the actual operational efficiency equal to the design efficiency. When the heat user regulate the system locally, the water injector will operate in inefficient zone if the actual operating efficiency of the water injector is 20% less than the design efficiency, in which case the water injector should be regulated.
