Abstract

the invention provides a reversing power turbine rotating mechanism system and relates to the field of energy power equipment. The problem that a direct reversing function of an existing gas turbine cannot be realized as a power turbine duct cannot be perform through flow switching is solved. According to the reversing power turbine rotating mechanism system, an external casing, a middle casing and a front casing are connected with each other in sequence from left to right; a nozzle ring is connected with the left end surface of the external casing through a connecting ring; the internal casing is inserted in the external casing; the left end of the internal casing is connected with the nozzle ring; a movable leaf disc is matched with the nozzle ring; the left end of the movable leaf discis fixedly connected with an external power turbine rotor; a switching valve is connected to each first boss at the right end of a casing internal sleeve of the external casing in a rotatable manner;an input end of a connecting rod mechanism penetrates through the middle casing and is fixedly connected with a corresponding electric cylinder; and an output end of the connecting rod mechanism is connected with the upper part of the switching valve in a rotatable manner. The reversing power turbine rotating mechanism system is used for through flow switching of the power turbine duct of the gasturbine and realizes the reversing function of the gas turbine.

Description

technical field [0001] The invention relates to the field of energy power equipment, in particular to a reversible power turbine rotating mechanism system. Background technique [0002] Since its birth, gas turbines have been favored by navies of various countries due to their high power density and rapid response, and have become the main power equipment for large surface ships. The United States, Britain and Russia have developed multiple types of surface ships equipped with gas turbines, and the design technology of gas turbines is becoming more and more perfect. my country has greatly improved the technical level of my country's marine gas turbines through the introduction of advanced marine gas turbine technology and localized research and development, but the cutting-edge science and technology of gas turbines lags behind the aforementioned developed countries. Since the 1970s, Western countries have started to study gas turbine direct reversing turbine technology, an...
