Electromechanical redundancy electronic speed regulator

Abstract

The invention discloses an electromechanical redundancy electronic speed regulator, and the speed regulator is composed of an actuator (1), a sensor and a control unit, wherein the actuator (1) comprises a driving shaft (11), a front end cover (14), a rear end cover (112), a sleeve (17) and an electromagnetic driving assembly arranged in the sleeve (17). An elastic clamping ring accessory (13) isarranged at the top end of the driving shaft (11). The electromagnetic driving assembly is composed of a coil winding (19), an armature (110), a wiring terminal (111), a coil winding outgoing line (13), a rolling bearing (15), a limiting spring seat (16) and a spring (18). According to the electromechanical redundant electronic speed regulator, the actuator (1) can directly exchange with a mechanical speed regulator conveniently and quickly, also can carry out the composite control on devices together with the mechanical speed regulator. Moreover, the size is small, and the regulation precision is high.

Description

technical field [0001] The invention relates to an electronic governor, in particular to an actuator of an electromechanical redundant electronic governor. technical background [0002] Existing governors used for speed control of small and medium-sized vehicles, ships, fixed or mobile natural gas or diesel engines, and motion control in industrial processes can generally be divided into two types: mechanical governors and electronic governors. The speed governor has the characteristics of stable performance and strong anti-interference, but the control accuracy is not high, and the electronic speed governor is generally executed by the sensor installed on the monitoring object, the control unit that receives the sensor signal and processes it, and the controlled unit. It is composed of electronic governor, which has high control precision but is easily disturbed by external factors, such as unstable voltage or power failure, which may cause the electronic governor to not wo...

[0002] Existing governors used for speed control of small and medium-sized vehicles, ships, fixed or mobile natural gas or diesel engines, and motion control in industrial processes can generally be divided into two types: mechanical governors and electronic governors. The speed governor has the characteristics of stable performance and strong anti-interference, but the control accuracy is not high, and the electronic speed governor is generally executed by the sensor installed on the monitoring object, the control unit that receives the sensor signal and processes it, and the controlled unit. It is composed of electronic governor, which has high control precision but is easily disturbed by external factors, such as unstable voltage or power failure, which can cause the electronic governor to fail to work normally

[0003] Therefore, in the industrial control process, the combined effect control of the mechanical governor and the electronic governor is often used, but in the prior art, the actuators of the mechanical governor and the electronic governor are all rigid with the throttle lever. Connection, so when the mechanical governor and the electronic governor are used at the same time, mutual interference will occur, so that the mechanical governor and the electronic governor are installed on the machine and used separately according to specific needs, but the two The mutual switching of the governors cannot be carried out directly, and some adjustment work is required, which brings a lot of inconvenience to the use, especially in some occasions where the power cannot be interrupted, such as the auxiliary power generation of special vehicles
