Abstract

The invention discloses an engine air bleed valve control device and an engine control system. The engine air bleed valve control device comprises a rotation speed sensor, an electronic controller and an air bleed control valve. The electronic controller is connected with the air bleed electromagnetic valve. The air bleed electromagnetic valve is connected with an air bleed valve. The rotation speed sensor is used for sensing the rotation speed of an engine. The electronic controller is connected with the rotation speed sensor and used for collecting the rotation speed of the engine so as to control the air bleed electromagnetic valve to be switched on according to the rotation speed of the engine so that the air bleed valve can be opened or control the air bleed electromagnetic valve to be switched off according to the rotation speed of the engine so that the air bleed valve can be closed. According to the engine air bleed valve control device and the engine control system, the technical problems that when a traditional mechanical hydraulic control mode is adopted, the structure is complex, an air bleed valve is prone to being affected by oil pressure fluctuation, and the opportunity for opening or closing the air bleed valve is difficult to adjust are solved, the structure is simple, and the control precision and the reliability are high.

Description

technical field [0001] The invention relates to the field of gas turbine engines, in particular to an engine bleed valve control device. In addition, the present invention also relates to an engine control system comprising the above-mentioned engine bleed valve control device. Background technique [0002] In the existing technology, such as figure 1 As shown, the engine uses the working oil in the fuel regulator to control the opening or closing of the bleed valve. The fuel regulator is provided with a first diverter valve 159 and a second diverter valve 160, which respectively provide working lubricating oil to the oil chambers of the eighth stage air release valve 191 and the fifth stage air release valve 192 of the compressor. The upper end surfaces of the first diverter valve 159 and the second diverter valve 160 bear the pressure of Pn lubricating oil, and the lower end faces bear the pre-tightening force of the spring. When the engine starts to start, the rotating...
