Embodiment Construction

[0028] The specific embodiment of the present invention is as shown in the accompanying drawings; Take the control of the marine rotary vane steering gear as an example for further description; AC servo motor 1 is connected with bidirectional quantitative pump 3 through speed changer 2; ) is sealedly connected with the two inlets and outlets of the input end of the shuttle valve (4), and communicated with the pressure oil tank 10. Shuttle valve 4, lock valve 5, bypass valve 6, safety valve 7, 8; their oil passages are sealed and connected with connecting channels to jointly form an oil control unit, and the two interfaces A and B at the output end of the oil control unit are connected with the hydraulic actuator, that is, the marine Servo is connected. Since the AC servo motor 1 has the characteristics of stepless speed change, controllable direction change rotation, settable torque and position control, etc., its function is to realize the flow control, reversing control, pre...

Abstract

The invention belongs to a direct driving volume servo control power device which controls a rotary vane actuator system in an electro-hydraulic servo technical field. The invention consists of a servo motor, a bidirectional valve, a shuttle valve, a lock valve, a safety valve, an oil storage tank and a connecting oil path; two output terminals A and B of the oil path are connected with a hydraulic execution mechanism in positive or reversed rotation direction or steering; the servo motor receives the electric instruments to implement the flux control, steering control, pressure control, program control and position control of the hydraulic system; the invention is a fully novel electro-hydraulic servo control technology implementing the automatic control and integrating the machine, electricity and liquids into a whole. The invention can be widely applied to the fields such as ship marine engineering, mechanics, mines, metallurgy, nuclear power, pressure processing and automobile manufacture, etc.

Description

technical field [0001] The invention belongs to the field of electro-hydraulic servo technology and is a direct-drive volumetric servo control power device for controlling a marine rotary vane steering gear system. Background technique [0002] At present, the traditional electro-hydraulic servo system is composed of AC motor, variable pump, electro-hydraulic servo valve, overflow valve, etc.; because the traditional electro-hydraulic servo system is driven by an ordinary AC motor to drive the hydraulic variable pump to generate hydraulic power to push the actuator to work, The electro-hydraulic servo valve controls the variable pump according to the action command to realize the action of changing speed and direction. Because the oil circuit of the electro-hydraulic servo system in the prior art is an open oil circuit, it has low efficiency (≤30%), high working noise (above 90dB), large amount of working medium (tens of tons), and waste generated. Difficult medium handling...
