Dual-pulse speed regulator

Abstract

The invention discloses a dual-pulse speed regulator. The dual-pulse speed regulator is suitable for series diesel engines with the power of about 5,000 kW, and is a multifunctional speed regulator which adopts mechanical, hydraulic and electronic compound control. The dual-pulse speed regulator can simultaneously receive mechanical signals and electric signals, and respectively control the rotating speed of a diesel engine independently. When electronic control fails, rapid and automatic switch of the electromechanical control can be realized; and an executing mechanism of the dual-pulse speed regulator adopts a mechanical-hydraulic structure, is similar to the structure of a mechanical-hydraulic speed regulator, and has the same interface size as that of the mechanical-hydraulic speed regulator. The dual-pulse speed regulator improves the reliability of a marine diesel engine electronic regulator remarkably, and contributes to realization of marine engine room automation.

Description

technical field [0001] The invention belongs to the field of diesel engines, and in particular relates to a double-pulse governor suitable for series diesel engines with a power of about 5000kW. Background technique [0002] With the rapid development of electronic technology, the governor for high-power diesel engine has developed to today, and great changes have taken place. From the earliest purely mechanical governors and hydraulic governors, electronic governors and electro-hydraulic governors are commonly used today. [0003] The speed sensing mechanism, control mechanism and actuator of the mechanical speed governor are all mechanical, which has the advantage of high reliability, but has the disadvantages of small working capacity and low precision of the speed governor, and is generally only used in small high-speed diesel engines. [0004] The speed sensing mechanism of the hydraulic governor adopts a mechanical method, while the control mechanism and the actuator ...

AI Technical Summary

Problems solved by technology

[0005] The speed sensing mechanism, control mechanism and actuator of the electronic governor all adopt electronic methods, which are characterized by high speed regulation accuracy, but small working capacity and poor reliability. It is generally used in small high-speed diesel engines with low reliability requirements.

[0006] The speed sensing mechanism of the electro-hydraulic speedometer adopts a mechanical method, the control mechanism adopts an electronic method, and the actuator adopts a hydraulic method, so it has high working capacity and speed regulation accuracy, but its reliability is average, and it has been widely used in Medium and low-speed high-power diesel engines with high requirements
