Embodiment Construction

[0024] Such as figure 1 , figure 2 As shown, it is the turbine power automatic adjustment device of the present invention. The turbine pump power automatic adjustment device is composed of a lift valve and an air intake valve, and is integrated with the turbo pump, wherein the air intake adjustment valve is placed in the cavity of the turbine air intake housing Inside, the fastening method between the intake regulating valve and the turbine intake casing is fixed by locking and fixing the compression nut 7 and the lock nut 9 .

[0025] The lift valve is fixedly placed on the support of the turbine inlet casing, and the inlet control channel 13 and the outlet return channel 14 in the form of a through-rod are connected between the inlet valve and the oil passage of the two. The spool assembly (small spool 16, spool 19) is composed of two split pistons with different diameters. The small spool feels the force of the pressure difference between the front and rear of the pump li...

Abstract

The invention relates to a device for automatically adjusting the power of a turbine pump. The device comprises a lift valve arranged outside a turbine air inlet casing, an air inlet valve arranged in the turbine air inlet casing, and an inlet chamber control channel and an outlet chamber control channel which are used for connecting an air inlet valve oil circuit and a lift valve oil circuit. The device solves the technical problem that the jet pipe and air inlet passage of an aspirated engine, which works under large airspace, high Mach number and large-scale variable working conditions, are difficult to adjust, ensures that the output power of the turbine pump is within a rated value range and improves the processing and assembly manufacturability of the turbine pump.

Description

technical field [0001] The invention relates to a turbine pump power automatic adjustment device used in the engine hydraulic servo system in the field of aviation and aerospace, which can be widely used in various hydraulic servo systems using turbo pumps as power sources on aviation and aerospace engines, such as nozzles The adjustment system is an adjustable air inlet control system, which can be used for aircraft wings, hydraulic steering gear control and other systems, and can also be used for engine fuel supply adjustment systems. Background technique [0002] With the development of various types of air-breathing engines, especially the rapid development of sub-combustion / scramjet engine technology, its flight Mach number continues to increase, and the range of working airspace widens. The engine must adopt tail nozzle adjustment control technology, and Intake port adjustment control technology, so that the engine can better play its performance benefits. The power s...
