Abstract

The invention provides a device for regulating a guide blade of a turbine, comprising a case (1), a regulating cam (3) arranged on the case (1) in a rotatable manner, as well as a follow-up valve (4) and an actuating mechanism (5) which are contained and arranged in the case (1), wherein the follow-up valve (4) and the actuating mechanism (5) interact to provide a rotating power for the guide blade. In the invention, the device for regulating the guide blade is hydraulically driven, and the angle of the guide blade can be continuously and steplessly regulated, thus the angle of the guide blade can be matched with the blade airflow air suction angle requirement at different rotating speeds and the thermal energy conversion efficiency of a turbine blade is greatly improved.

Description

technical field [0001] The invention relates to the field of turbomachines, in particular to a turbine guide vane adjuster. Background technique [0002] Guide vanes are installed in power turbines, and the function of the guide vanes is to change the direction of the airflow before entering the turbine blades. In order to allow the power turbine blades to obtain a better angle of intake airflow, an adjustable-angle guide vane (also called a vane) is usually designed in front of the turbine blades. At present, guide vanes are adjusted in multiple stages using guide vane regulators. However, the existing guide vane adjusters can only adjust the guide vane angle to a few fixed positions. Contents of the invention [0003] The purpose of the present invention is to provide a turbine guide vane adjuster to solve the technical problem that the existing guide vane adjuster can only adjust the guide vane angle to several fixed positions and can continuously adjust steplessly. ...
