Abstract

The invention discloses a working device of an engine waste gas power turbine driving water pump. The working device comprises a runoff power turbine, a centrifugal water pump and a common shaft; therunoff power turbine comprises a volute, a turbine impeller, a peripheral intake port and an axial exhaust port; the centrifugal water pump comprises a shell, a water pump impeller, an axial water inlet and a peripheral water outlet; the turbine impeller and the water pump impeller are arranged at the two ends of the common shaft; the axial exhaust port and the axial water inlet are oppositely arranged; the volute is fixedly connected with the shell through a mounting body; and the common shaft is supported by the mounting body. The device changes a driving mode of the centrifugal water pump without influencing a cooling path of a traditional cooling system and without influencing the engine power.

Description

technical field [0001] The invention relates to a working device for driving a water pump, in particular to a working device for driving a water pump driven by an engine exhaust gas power turbine, and belongs to the technical field of automobile energy saving. Background technique [0002] In the total heat of the engine fuel, only 25% to 40% of the heat is converted into effective work, and the remaining 60% to 75% are lost. Among them, it is mainly taken away by the exhaust gas, and secondly passed to the coolant; the heat taken away by the coolant accounts for 10% to 35% of the total heat, and the heat taken away by the exhaust gas accounts for 25% to 50% of the total heat. Utilization of waste energy has always been a hot topic in the research of engine energy saving; looking at the research on the utilization of engine waste heat at home and abroad, it can be divided into two ways: using exhaust waste heat and using waste heat in engine coolant in terms of heat source u...
