Abstract

The invention discloses a starting acceleration adjusting device. The starting acceleration adjusting device comprises a device body, wherein a channel is arranged in the device body, a supporting point base is arranged in the channel, the two ends of a lever extending into a first installation channel and a second installation channel correspondingly is arranged on the supporting point base in asupporting mode; the first installation channel is filled with first gas, and the second installation channel communicates with an oil return system; a third installation channel is further arranged in the device body, a membrane sheet is arranged between the third installation channel and the first installation channel, the membrane sheet is provided with a first ejector pin component with the bottom end abutting against the first end of the lever, and the third installation channel communicates with a gas compressor in an engine so as to introduce second gas; and a fourth installation channel and a fifth installation channel are further arranged in the device body, the fourth installation channel communicate with the fifth installation channel and a fuel oil metering device correspondingly so as to introduce fuel oil and control oil, a second ejector pin component with a bottom end abutting against the second end of the lever is arranged in the fourth installation channel, and a control oil valve with the bottom end connected with the second end of the lever is arranged in the fifth installation channel.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a start-up acceleration regulating device. Background technique [0002] China has a vast territory, with different climates and environmental conditions. Gas turbines, especially those used to power military vehicles, have a shorter start-up time, which means preemptive strikes. The length of start-up time of a gas turbine is an important indicator of whether the start-up performance is good. When the existing gas turbine starts, it is often unsuccessful due to rich or lean fuel, especially when it is applied in a new environment, due to the change of air pressure in the new environment, it will lead to a change in the pressure of the compressor output gas, which will eventually affect the gas entering the combustion chamber. The change of gas pressure and fuel ratio prolongs the start-up time of the gas turbine, and the success rate of start-up is low, requiring repeated start-ups m...
