Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] As shown in the figure, a new type of axial flow fan stator blade adjustment system includes a servo motor 1, a bidirectional quantitative gear pump 2, and an oil tank 14. The bidirectional quantitative gear pump 2 is fixed inside the oil tank 14 and driven by the servo motor 1 to rotate. It also includes two hydraulic cylinders 6 and adjusting oil cylinders 7 respectively connected thereto for adjusting the vane angle. The two hydraulic cylinders 6 are respectively connected to the adjusting oil cylinders 7 through couplings 12 .
[0024] Displacement sensors are arranged inside the two hydraulic cylinders 6, which are used to detect the displacement of the piston rod of the hydraulic cylinder and adjust the position of the hydraulic cylinder after the signal is fed back to the controller; A pressure sensor is provided to dete...
