Abstract

The invention relates to an electric motor equipment system and discloses an integrated diesel engine digital electronic governor. The digital electronic governor comprises a casing, a control panel, a tachometer wheel arranged on the main shaft of an injection pump, an electronic throttle module, an actuator body and a revolution speed transducer, wherein revolution speed transducer and the electronic throttle module are arranged on the control panel, the electronic throttle module is connected with the control panel through a throttle wire, the revolution speed transducer and the actuator body are connected with the control panel through wires, and the control panel and the actuator body are arranged on the casing to constitute a whole. The entire electronic governor system can be integrated by adopting the above structure; and the volume is smaller than that of the original mechanical governor, the speed-regulating fitness of the governor is good, the speed-regulating sensitivity is high and the inertia is small, thus the fuel oil can be completely combusted, the fuel consumption is low, the exhaust emission is little and the governor can be widely popularized and used while costing low cost.

Description

technical field [0001] The invention relates to a motor equipment system, in particular to an integrated diesel engine digital electronic governor. Background technique [0002] The operation of the diesel engine needs to be stabilized by a speed adjustment device, called a governor. The fuel supply amount of the diesel engine commonly used at present is determined by the position of the plunger of the fuel injection pump, and the position of the plunger of the fuel injection pump is determined by The plunger position controls the rack to adjust. The governor uses the "negative feedback" mode to stabilize the speed of the diesel engine and prevent the speed of the engine. The principle of the mechanical governor The speed is adjusted by the balance of the centrifugal force and the spring force generated when the flying block rotates; when the spring force is constant, the centrifugal force generated when the speed is high and the rapid rotation is high, and the position of t...
