Abstract

The gas turbine inlet guide page adjustment device includes a base (24), a motor (1) on the base (24), an oil tank (25), and a first accumulator (21), a first diaphragm accumulator ( 7), the first solenoid valve (8), the high-frequency response servo valve (9), the hydraulic control check valve (10), the second solenoid valve (11), the third solenoid valve (17), the first check valve (19), the first relief valve (20). The invention has the advantages of simple structure, reasonable design and high control precision, and the guide page can be adjusted at any angle between fully open and fully closed.

Description

Technical field: [0001] The invention relates to a hydraulic device, in particular to a device for adjusting the angle of a large gas turbine inlet guide leaf. Background technique: [0002] At present, the angle of the guide page of the large gas turbine inlet is mainly adjusted in the form of a motor acceleration and deceleration machine or a direct control method of an ordinary oil pressure system. The form of the motor acceleration and deceleration machine has the disadvantages of large volume, large inertia, and slow dynamic response; while the direct control of the ordinary hydraulic system has no intermediate process, poor control accuracy, and only two states of full open and full close. Invention content: [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a hydraulic device with simple structure, high precision, and the ability to adjust any angle of the inlet guide page of the gas turbine. [0004] In order to ac...
