Abstract

The invention relates to a diesel engine speed regulation control field, in particular to a device for controlling speed regulation of a guyed diesel engine, which solves the problem that the diesel engine of the prior guyed speed regulator can not meet a use requirement of a traction engine. The control device comprises a mechanical transmission unit and an electric control unit, the mechanical transmission unit comprises a throttle stayguy of the diesel engine, a stepping motor that a pinion is fixed on the motor shaft and a fixed base plate, wherein the fixed base plate is fixed with a sector gear which is meshed with the pinion, one end of a stayguy is fixed with the sector gear, the right lower side of the sector gear arranged on the fixed base plate is provided with a rectangular through hole; and the electric control unit comprises an encoded driver controller and a logic controller, and the output ends of the logic controller are connected with incoming line ends of three-phase power of the stepping motor through current-limiting resistance. The device has the advantages of rational and concise structure, convenient operation and installation, high accuracy of speed regulation, strong adaptability and high cost performance, and can be widely applied to the fields of diesel locomotives, track cars and subway tractors with small power.

Description

technical field [0001] The invention relates to the field of diesel engine speed regulation control, in particular to a pull-wire type diesel engine speed regulation control device capable of precisely controlling the speed of the diesel engine. Background technique [0002] In the application fields of automobiles and ships, the pull-wire governor is a traditional speed regulating device. Its speed regulation is smooth, simple and reliable, and it is widely used. It is suitable for occasions that do not need precise control of the diesel engine speed; Traction locomotives in the field need to accurately control the speed of diesel engines in stages to meet the needs of constant power control. Because the diesel engine adopting the existing stay-wire governor cannot meet the use requirements of the traction locomotive. For many years, special-purpose diesel engines or electronic injection diesel engines have been used to meet this special demand, and the cost is extremely h...
