Problems solved by technology

However, compared with the gearbox connection method, this direct connection method lacks the buffer between the two. When the operation of the gas turbine is abnormal, such as when the main shaft torque of the gas turbine is abnormally increased, the inspiration motor is easily overloaded and blocked. burn out

[0064] Figure 5 The structure of the second embodiment of the present invention is shown. Wherein, the same or corresponding features as those of the first embodiment are denoted by the same or similar reference numerals, and the following disclosure mainly describes the features different from those of the first embodiment, without further detailed description of the same features . Unless stated to the contrary, the features described in the first embodiment are also applicable to the second embodiment.

[0065] Such as Figure 5 As shown, in the gas turbine 100 of the second embodiment, the motor shaft 213 of the generator 200 is supported on the motor base 214 through the magnetic suspension bearing 220'. The magnetic suspension bearing 220' can be an electrically activated magnetic suspension bearing, which is connected to a power source. When the magnetic suspension bearing 220' is energized, it generates a magnetic field, so that the motor shaft 213 is suspended in ...

Abstract

A gas turbine comprises a compressor, a turbo and a combustor. The gas compressor comprises a compressor impeller and a first rotating shaft; the turbo comprises a turbo impeller and a second rotatingshaft; the second rotating shaft and the first rotating shaft are fixedly connected or integrally formed, thereby forming a spindle of the gas turbine; the combustor is located at the downstream partof the compressor and the upstream part of the turbo; the gas turbine further comprises a starter / generator motor; and a rotating shaft of the starter / generator motor is connected onto the spindle through a rod-like connecting device. The gas turbine is high in operation reliability; moreover, the phenomenon that parts of the gas turbine are damaged due to operation fluctuation can also be prevented, and thus, safety is enhanced.

Description

technical field [0001] The invention relates to the field of power devices, in particular, the invention discloses a gas turbine. Background technique [0002] A gas turbine is an internal combustion powered mechanical device. The operating principle of a gas turbine is to use the fuel combustion product as a working medium to continuously flow into the impeller of the gas turbine to drive the impeller to rotate, thereby converting the chemical energy of the fuel into mechanical energy. [0003] Currently commonly used gas turbines can be divided into heavy-duty gas turbines, light-duty gas turbines, and micro gas turbines according to their structural forms, and these types of gas turbines can be used in various occasions, such as aeroengines, ship engines, or in generator sets, etc. . The advantage of the gas turbine is that it can easily carry out the integrated expansion of multiple gas turbines, it can adapt to a variety of fuels, the fuel consumption rate is low, the...
