Forwards and backwards rotating water turbine and steam turbine

Abstract

The invention provides a forwards and backwards rotating water turbine and steam turbine. The forwards and backwards rotating water turbine and steam turbine comprises a volute shell, forwards rotating impellers, backwards rotating impellers, forwards and backwards gear sets, rotary connectors and a gear case. The working process of the forwards and backwards rotating water turbine and steam turbine is that pressure fluid enters the forwards rotating impellers from the rotary connectors and is sprayed out of spraying openings of the forwards rotating impellers to apply work, under the action of the pressure fluid, all stages of the concentric forwards rotating impellers and all stages of the concentric backwards rotating impellers generate mutually-pushed relative force in opposite directions, and the generated power in the opposite directions is combined by the forward and backward gear sets to be synchronously and coaxially output in the same direction. According to the forwards andbackwards rotating water turbine and steam turbine, impeller blades are simple in structure, no stationary blade exists, only movable blades exist, and the manufacturing material, the weight and the size are reduced. The forwards and backwards rotating water turbine and steam turbine is simple in structure, easy to manufacture, low in cost and high in efficiency. The forwards and backwards rotating water turbine and steam turbine can be applied to a plurality of fields such as water turbines, pneumatic equipment and steam turbines and can be manufactured into a small type and a mini type and can also be manufactured into a medium type and a large type.

Description

Technical field: [0001] The invention relates to the fields of turbine engines, water turbines and steam turbines. Background technique: [0002] Water turbines, also known as water turbine engines, are generally used in the hydropower industry. Steam turbines, also known as steam turbine engines, are generally used in thermal and nuclear power generation industries. They have a long history and play an important role in the development of human life and the progress of civilization. [0003] At present, there is not much improvement in the structure of this type of old machines, and most of them are used for medium and large scales. The production cost of traditional technology is high, the body is heavy, the structure is complicated, the production is difficult, and the efficiency is difficult to further improve. It also limits their more functions, such as: small and micro biomass power generation, small and micro distributed cogeneration of heat and power, small and micr...
