扩展资料

调速器用于减小某些机器非周期性速度波动的自动调节装置。可使机器转速保持定值或接近设定值。水轮机、汽轮机、燃气轮机和内燃机等与电动机不同,其输出的力矩不能自动适应本身的载荷变化,因而当载荷变动时,由它们驱动的机组就会失去稳定性。

这类机组必须设置调速器,使其能随着载荷等条件变化,随时建立载荷与能源供给量之间的适应关系,以保证机组作正常运转。

调速器的理论和设计问题,是机械动力学的研究内容。调速器的种类很多。其中应用最广泛的是机械式离心调速器。而以测速发电机或其他电子器件作为传感器的调速器,已在各个工业部门中广为应用。

Governor is a kind of automatic regulating device, its function is to automatically increase or decrease the fuel supply of fuel injection pump according to the change of diesel load, so that the diesel engine can run at a stable speed.

Governor has been widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting mediation, computer power cooling, DC fans, etc.

Extended data

An automatic regulator used to reduce aperiodic speed fluctuations in certain machines. Can make the machine speed to maintain a fixed value or close to the set value. Unlike electric motors, water turbines, steam turbines, gas turbines and internal combustion engines, their output torque cannot automatically adapt to their own load changes, so when the load changes, the unit driven by them will lose stability.

This kind of unit must be set up governor, so that it can change with the load and other conditions, at any time to establish the load and energy supply between the adaptive relationship, to ensure the normal operation of the unit.

The theory and design of governor is the research content of mechanical dynamics. There are many kinds of governors. One of the most widely used is the mechanical centrifugal governor. The speed governor, which takes the speed generator or other electronic devices as the sensor, has been widely used in various industrial sectors.
